127AbstractBackground: Significant associations exist between psychological pain, unmet mental health need, and frequency and severity of substance use among people who use drugs (PWUD), but no studies have analyzed the relationship of these variables to non-fatal overdose. Methods: We conducted a cross-sectional survey of people who used opioids non-medically in Baltimore, Maryland (n = 563) as part of a broader harm reduction-focused evaluation (PROMOTE). The outcome was self-reported recent (past 6 months) non-fatal overdose; exposures of interest were recent self-reported unmet mental health need, experiencing daily “long-lasting psychological or mental pain” (vs. < daily), and daily multi-opioid use (vs. none/one opioid used). Path analysis was used to model direct relationships between these variables, personal characteristics (race, gender, experiencing homelessness, drug injection) and overdose. Results: 30% of the sample had experienced a recent non-fatal overdose, 46% reported unmet mental health need, 21% reported daily psychological pain, and 62% used multiple types of opioids daily. After adjusting for covariates, daily multi-opioid use (aOR = 1.78, p = 0.03) and unmet mental health need (aOR = 2.05, p = 0.01) were associated with direct, significant increased risk of recent overdose. Significant pathways associated with increased odds of unmet mental health need included woman gender (aOR = 2.23, p = 0.003) and daily psychological pain (aOR = 4.14, p = 0.002). In turn, unmet mental health need associated was with greater odds of daily multi-opioid use (aOR = 1.57, p = 0.05). Discussion: Unmet mental heath need and daily psychological pain are common experiences in this sample of PWUD. Unmet mental health need appears on several pathways to overdose and associated risk factors; improving access to mental healthcare for PWUD (particularly women) expressing need may be an important harm reduction measure.NIMBYism and Harm Reduction Programs: Results from Baltimore City

163AbstractDrug criminalization creates significant barriers to prevention and treatment of substance use disorders and racial equity objectives, and removal of criminal penalties for drug possession is increasingly being endorsed by health and justice advocates. We present empirical data estimating the share of U.S. adults who support eliminating criminal penalties for possession of all illicit drugs, and examine factors associated with public support. Data from the Johns Hopkins COVID-19 Civic Life and Public Health Survey, a probability-based nationally representative sample of 1222 U.S. adults, was collected from November 11–30, 2020. Support for decriminalizing drug possession was assessed overall and by sociodemographic factors and attitudes towards politics and race. Correlates of support were examined using multivariable logistic regression. Thirty-five percent of adults supported eliminating criminal penalties for drug possession in the U.S. In adjusted regression models, respondents who were younger or identified as politically liberal were more likely to support decriminalization relative to other groups, and respondents who were Hispanic or identified strongly with their religious beliefs were less likely to support decriminalization. Among white respondents, greater racial resentment was strongly associated with reduced support for drug decriminalization. Support for drug decriminalization varies considerably by beliefs about politics and race, with racial resentment among white Americans potentially comprising a barrier to drug policy reform. Findings can inform communication and advocacy efforts to promote drug policy reform in the United States.Selling sex in the context of substance use: social and structural drivers of transactional sex among men who use opioids in Maryland

1AbstractBackground: Transactional sex is an important driver of HIV risk among people who use drugs in the USA, but there is a dearth of research characterizing men’s selling and trading of sex in the context of opioid use. To identify contextually specific factors associated with selling or trading sex in a US population of men who use drugs, we cross-sectionally examined social and structural correlates of transactional sex among men who use opioids (MWUO) in Anne Arundel County and Baltimore City, Maryland. Methods: Between July 2018 and March 2020, we used targeted sampling to recruit men reporting past-month opioid use from 22 street-level urban and suburban recruitment zones. MWUO completed a 30-min self-administered interview eliciting substance use histories, experiences with hunger and homelessness, criminal justice interactions, and transactional sex involvement. We identified correlates of recent (past 3 months) transactional sex using multivariable log-binomial regression with cluster-robust standard errors. Results: Among 422 MWUO (mean age 47.3 years, 73.4% non-Hispanic Black, 94.5% heterosexual), the prevalence of recent transactional sex was 10.7%. In multivariable analysis, younger age (adjusted prevalence ratio [aPR] 0.98, 95% confidence interval [95% CI] 0.97–0.99, p < 0.001), identifying as gay/bisexual (aPR = 5.30, 95% CI 3.81–7.37, p < 0.001), past-month food insecurity (aPR = 1.77, 95% CI 1.05–3.00, p = 0.032), and injection drug use in the past 3 months (aPR = 1.75, 95% CI 1.02–3.01, p = 0.043) emerged as statistically significant independent correlates of transactional sex. Conclusions: Synergistic sources of social and structural marginalization—from sexuality to hunger, homelessness, and injection drug use—are associated with transactional sex in this predominantly Black, heterosexual-identifying sample of MWUO. Efforts to mitigate physical and psychological harms associated with transactional sex encounters should consider the racialized dimensions and socio-structural drivers of transactional sex among MWUO.The Epidemiology of Sapovirus in the Etiology, Risk Factors, and Interactions of Enteric Infection and Malnutrition and the Consequences for Child Health and Development Study: Evidence of Protection Following Natural Infection

1334-1341AbstractBackground. Sapovirus is one of the principal agents of acute viral enteritis in children. Because it has not been routinely included in diagnostic evaluations, the epidemiology and natural history remain poorly described. Methods. A birth cohort of 1715 children from 8 countries contributed surveillance samples (n = 35 620) and diarrheal specimens (n = 6868) from 0 to 24 months of age. Sapovirus was detected by quantitative polymerase chain reaction concurrently to other enteropathogens using multiarray cards. Logistic regression was used to identify risk factors, and longitudinal models were employed to estimate incidence rates and evaluate evidence of protective immunity. Results. Sapovirus was detected in 24.7% (n = 1665) of diarrheal stools and 12.8% (n = 4429) of monthly surveillance samples. More than 90% of children were infected and 60% experienced sapovirus diarrhea in the first 2 years of life. Breastfeeding and higher socioeconomic status were associated with reduced incidence of infection and illness. Specimens with sapovirus detected had an increased odds of coinfection with rotavirus (odds ratio [OR], 1.6 [95% confidence interval {CI}, 1.3–2.0]), astrovirus (OR, 1.5 [95% CI, 1.3–1.7]), adenovirus (OR, 1.3 [95% CI, 1.1–1.5]), and Shigella (OR, 1.4 [95% CI, 1.3–1.6]). Prior infection with sapovirus conferred a risk reduction of 22% for subsequent infection (hazard ratio [HR], 0.78 [95% CI, .74–.85]) and 24% for subsequent diarrhea (95% CI, 11.0%–35.0%; HR, 0.76). Conclusions. Sapovirus is a common cause of early childhood diarrhea. Further research on coinfections is warranted. Evidence of acquired immunity was observed even in the absence of genotype-specific analysis for this pathogen of known genetic diversity.Understanding the longitudinal relationship between substance use and violent victimization among street-based women who exchange sex in Baltimore, Maryland

109AbstractBackground: Women who exchange sex (WES) experience extensive interpersonal violence from multiple perpetrators. Violence towards WES contributes to poor mental and behavioral health outcomes, including high rates of drug use. However, it is difficult to disentangle the temporal relationship between drug use and violence among WES. Methods: We used data from 251 WES, who completed baseline and 6-month follow up surveys. WES reported baseline sociodemographic characteristics, including homelessness and hunger. Participants reported their drug use by type and violent experiences by perpetrator at each time point. We conducted a path analysis examining the associations between drug use and violent victimization over time. Results: Participants were on average 37.8 years old, non-Hispanic White (57.4%) and experiencing high levels of structural vulnerability (59.4% homelessness; 58.6% weekly hunger). Drug use and violence were significantly correlated within each time point. Prospectively, baseline violent victimization was significantly associated with drug use (ß (SE) = 0.13 (0.06)) and violence (ß (SE) = 0.47 (0.05)) at follow up. Baseline drug use was associated with drug use at follow up (ß (SE) = 0.45 (0.05)) but was not significantly associated with violence at follow up (ß (SE) = 0.10 (0.06)). Conclusions: Violence and drug use are closely linked in this population; and violence appears to facilitate sustained drug use. Interventions to address the dual epidemics of violence and substance use in this population should address underlying trauma as well as socio-structural drivers of violence as well as tailored harm reduction services for this population.Confirmatory Factor Analysis and Construct Validity of the Internalized Sex Work Stigma Scale among a Cohort of Cisgender Female Sex Workers in Baltimore, Maryland, United States

713-723AbstractInternalized sex work stigma among cisgender female sex workers (FSW) is produced within contexts of social marginalization and associated with a range of ill-effects, including psychological distress, and lower rates of healthcare-seeking. This study seeks to uncover latent domains of the new Internalized Sex Work Stigma Scale (ISWSS) using data from 367 FSW in Baltimore, Maryland, USA. The sample was 56% white with high substance use (82% smoked crack cocaine, 58% injected any drug). The average ISWSS score was 34.8 (s.d. = 5.8, possible range: 12–48) and internal consistency was high (0.82). Confirmatory factor analysis revealed four subscales: worthlessness, guilt and shame, stigma acceptance, and sex work illegitimacy. Internal consistency of subscales was high (0.69–0.90); the scale also demonstrated construct validity with depression and agency. In bivariate logistic regressions, higher ISWSS, worthlessness, shame and guilt, and acceptance scores predicted higher odds of rushing client negotiations due to police. In unadjusted multinomial regressions, feeling respected by police predicted lower ISWSS, worthlessness, guilt and shame, acceptance, and illegitimacy scores. Identified factors are congruent with existing literature about how FSW manage sex work-specific stigma. Understanding the unique dimensions and impacts of internalized sex work stigma can inform interventions and policy to reduce morbidities experienced by FSW.Food access among people who inject drugs in West Virginia

1AbstractBackground: The substance use epidemic in the United States continues to drive high levels of morbidity and mortality, particularly among people who inject drugs (PWID). Poor access to food often co-occurs with drug use and contributes to associated sequelae, such as risks for HIV and diabetes. The objective of this study was to examine factors associated with adequate food access among PWID in a rural Appalachian community. Methods: Cross-sectional surveys were used to collect data among PWID aged 18 and older in Cabell County, West Virginia. Frequency of hunger and sociodemographic, structural and drug use characteristics were measured. Adequate food access was defined as reporting ‘never’ going to bed hungry at night in the past six months. Pearson’s χ2 and t-tests and multivariable logistic regression were used to identify factors associated with food access. Results: Only 71 individuals (17%) reported never going to bed hungry at night in the past six months. Adjusted odds of having adequate food access were higher among PWID who completed high school (aOR 2.94; P = 0.010) and usually used drugs alone (aOR 1.97; P = 0.025), and lower among PWID who were female (aOR 0.51; P = 0.037), experienced homelessness (aOR 0.23, P < 0.001), were recently arrested (aOR 0.50 P = 0.047), and engaged in receptive sharing of injection equipment (aOR 0.52, P = 0.035). Conclusions: We found extremely low food access in a population of PWID in Appalachia who are vulnerable to overdose and infectious disease transmission. Integrated interventions promoting food access are needed to improve the public health and wellbeing of people who inject drugs in Appalachia.Homotypic and Heterotypic Protection and Risk of Reinfection following Natural Norovirus Infection in a Highly Endemic Setting

222-229AbstractBackground: Norovirus is a leading cause of acute gastroenteritis worldwide, yet there is limited information on homotypic or heterotypic protection following natural infection to guide vaccine development. Methods: A total of 6020 stools collected from 299 Peruvian children between 2010 and 2014 were tested by norovirus real-time reverse-transcription polymerase chain reaction followed by sequence-based genotyping. Cox proportional hazards models were used to derive adjusted hazard ratios (HRs) of infection among children with vs without prior exposure. Results: Norovirus was detected in 1288 (21.3%) samples. GII.4 (26%), GII.6 (19%), and GI.3 (9%) viruses accounted for 54% of infections. Homotypic protection for GI.3 (HR, 0.35; P=.015), GI.7 (HR, 0.19; P=.022), GII.4 (HR, 0.39; P<.001), and GII.6 (HR, 0.52; P=.006) infections was observed. Hazard analysis showed that children with prior GII.4 infection exhibited heterotypic protection with a 48% reduction of subsequent GI.3 infection (HR, 0.52; P=.005). Prior exposure to GI.3, GII.2, and GII.17 infections enhanced susceptibility to subsequent infections with several other norovirus genotypes. Conclusions: Children up to 2 years of age infected with GII.4 noroviruses demonstrated both homotypic and heterotypic protection to reinfection with other genotypes. These data support the need for ongoing vaccine development efforts with GII.4 as the main component and caution the inclusion of genotypes that may enhance susceptibility to infections.Implications of attitudes and beliefs about COVID-19 vaccines for vaccination campaigns in the United States: A latent class analysis

24AbstractUnprecedented global efforts in vaccine development have resulted in effective vaccines for COVID-19. The pandemic response in the US has been highly politicized, resulting in significant opposition to public health efforts, including vaccines. We aimed to understand patterns of attitudes and beliefs about the COVID-19 vaccine to inform vaccination campaigns. 583 English speaking United States adults were surveyed November 18–29, 2020. Participants answered 11 questions about their attitudes and beliefs about a COVID-19 vaccine, including perceived vaccine effectiveness, likelihood of getting vaccinated, and concerns that vaccine development was rushed/influenced by politics. We conducted a latent class analysis to identify profiles of attitudes/beliefs about a COVID-19 vaccine. We identified four classes of COVID-19 vaccine beliefs. The pro-vaccine class (28.8%) was willing to get vaccinated and had broadly positive beliefs about the vaccine. The development concerns class (27.8%) was willing to get vaccinated but was concerned about the development process. The third class (22.6%) was largely unsure if they would get vaccinated and if their peer groups would be vaccinated. The forth class (anti-vaccine, 20.8%) was dominated by an unwillingness to get vaccinated, vaccine distrust, vaccine development concerns, and peers groups with negative vaccine intentions. Given the large proportion of individuals who were concerned about the COVID-19 vaccine development process, messaging about rigor and approval processes may be critical to securing this group's commitment to vaccination. Having scientific and cultural leaders endorse vaccination may also be influential.Incidence and predictors of violence from clients, intimate partners and police in a prospective US-based cohort of women in sex work

160-166AbstractObjective Gender-based violence threatens women's health and safety. Female sex workers (FSWs) experience violence disproportionately, yet prospective data on violence predictors is lacking. In the first US-based prospective FSW cohort study, we examine incidence rates (IRs) and predictors of violence from distinct perpetrators: paying clients, non-paying intimate partners and police. Methods The parent cohort (Sex Workers and Police Promoting Health In Risky Environments) recruited street-based cisgender FSWs in urban Baltimore, MD (n=250) with 5 assessments at 3-month intervals through 12-month follow-up. Stratifying by violence perpetrator, we characterise violence at baseline, IR over the study period and time-varying predictors using Poisson models. Results The violence IR per person year was highest for client-perpetrated violence (0.78), followed by intimate partner violence (IPV; IR 0.39), and police violence (IR 0.25). Prevalence over the 12-month follow-up period among participants with complete visit data (n=103), was 42% for client violence, 22% for IPV and 16% for police violence. In adjusted analyses, risk factors for incident violence varied across perpetrators and included entry to sex work through force or coercion (adjusted IR ratio (aIRR) IPV 2.0; 95% CI 1.2 to 3.6), homelessness (aIRR IPV 2.0; 95% CI 1.3 to 2.9; aIRR police 2.7; 95% CI 1.3 to 5.8) and daily injection drug use (aIRR client 1.9; 95% CI 1.2 to 3.0). Risk of incident client violence and IPV was elevated by past abuse from each respective perpetrator. Help-seeking following abuse was limited. Conclusions FSWs face profound, enduring risk for violence from a range of perpetrators, likely enabled by criminalisation-related barriers to justice and perpetrator impunity. FSWs represent a priority population for access to justice, trauma-informed healthcare and violence-related support services. Structural vulnerabilities including homelessness and addiction represent actionable priorities for improving safety and health.Perceived vulnerability to overdose-related arrests among people who use drugs in Maryland

98AbstractBackground: People who use drugs (PWUD) must weigh complex legal scenarios when seeking help during overdose events. Good Samaritan laws (GSL) offer limited immunity for certain low-level drug crimes to encourage PWUD to call 911. Drug-induced homicide laws (DHL) allow for criminal prosecution of people delivering drugs that result in overdose death and may exert opposing effects on the decision-making process. We examined whether perceptions of these laws were related to overall perceived vulnerability to overdose-related arrests, which can impact help-seeking and overdose mortality. Methods: We conducted a cross-sectional study of PWUD (N = 173) in Anne Arundel County, Maryland and measured sociodemographic characteristics, structural vulnerabilities, and knowledge of GSL and DHL. Perceived vulnerability to overdose-related arrest was defined as self-reported concern arising from calling 911, receiving medical help, or supplying drugs in the event of an overdose. Multivariable logistic regression was used to identify significant correlates of perceived vulnerability to overdose-related arrest. Results: Most participants were aware of DHL (87%) and half were aware of GSL (53%). Forty-seven percent of PWUD expressed concern about arrest during or due to an overdose. After adjustment, positive correlates of perceived vulnerability to arrest were non-white race (aOR 2.0, 95% CI 1.5-2.5) and hearing of somebody charged with DHL (aOR 3.1, 95%CI 1.9-5.0), and negative correlates were history of drug treatment (aOR 0.6, 95%CI 0.4-1.0), receiving naloxone (aOR 0.6, 95% CI 0.4-1.0), and having made, sold or traded drugs in the past 3 months (aOR 0.4, 95% CI 0.2-0.9). Conclusions: We report persisting concern about arrest during overdose events among street-based PWUD facing a complicated landscape of legal protections and liabilities. Findings demonstrate clear racial disparities in concern outside of an urban centre, where impacts of policing on health are less studied, and present evidence that DHL may compromise overdose prevention efforts. Changes to drug policy and enforcement including police nonattendance at overdose scenes may be necessary to promote help-seeking among PWUD and reduce overdose fatalities.Practical implications of naloxone knowledge among suburban people who use opioids

1AbstractBackground: Naloxone distribution programs have been a cornerstone of the public health response to the overdose crisis in the USA. Yet people who use opioids (PWUO) continue to face a number of barriers accessing naloxone, including not knowing where it is available. Methods: We used data from 173 PWUO from Anne Arundel County, Maryland, which is located between Baltimore City and Washington, DC. We assessed the prevalence of recently (past 6 months) receiving naloxone and currently having naloxone, the type(s) of the naloxone kits received, and the perceived ease/difficultly of accessing naloxone. We also assessed participants knowledge of where naloxone was available in the community. Results: One third (35.7%) of participants had recently received naloxone. Most who had received naloxone received two doses (72.1%), nasal naloxone (86.9%), and education about naloxone use (72.1%). Most currently had naloxone in their possession (either on their person or at home; 78.7%). One third (34.4%) believed naloxone was difficult to obtain in their community. Only half (56.7%) knew of multiple locations where they could get naloxone. The health department was the most commonly identified naloxone source (58.0%). Identifying multiple sources of naloxone was associated with being more likely to perceive that naloxone is easy to access. Discussion: Our results suggest that additional public health efforts are needed to make PWUO aware of the range of sources of naloxone in their communities in order to ensure easy and continued naloxone access to PWUO.Resilience among Cisgender and Transgender Women in Street-Based Sex Work in Baltimore, Maryland

148-156AbstractIntroduction: Resilience represents adaptability and empowerment and can buffer against the consequences of traumatic events. Cisgender and transgender women in street-based sex work are at high risk for trauma, yet data on their resilience are sparse. A clearer understanding of resilience and its correlates is useful for informing sex worker-centered interventions. Methods: Using the Connor-Davidson 10-item Resilience Scale (range, 0–40), we describe resilience among 165 cisgender and 42 transgender street-based women sex workers in Baltimore, Maryland. Longitudinal cohort data were used to examine correlates of resilience in each population. Analyses are conducted using multiple linear regression. Results: The mean resilience score was 24.2 (95% confidence interval, 23.6–24.8) among cisgender women sex workers and 32.2 among transgender women sex workers (95% confidence interval, 30.8–32.7). Among cisgender participants, positive correlates of resilience were being Black, Hispanic, or other race (ß = 2.7; p = .004), having housing (ß = 1.9; p = .034), social cohesion score (ß = 0.18; p = .047), and daily drug injection (ß = 3.7; p < .001); negative correlates of resilience were sexual violence (ß = –4.8; p = .006) and exposure to egregious police acts (ß = –0.6; p = .015). Among transgender participants, higher education level (ß = 8.8; p < .001), food security (ß = 3.5; p = .005), and housing stability (ß = 2.0; p < .001) were associated with increased resilience, and daily noninjection drug use (excluding marijuana; ß = –3.3; p < .001) and physical violence (ß = –2.9; p < .001) were associated with reduced resilience. Conclusions: This study is the first to characterize factors that may influence resilience among cisgender and transgender women sex workers. Results highlight tangible intervention targets for promoting mental health and safety among a uniquely vulnerable population of women.Agency in the fentanyl era: Exploring the utility of fentanyl test strips in an opaque drug market

84AbstractBackground: In Baltimore, the emergence of fentanyl and its analogues exacerbated an existing heroin crisis and increased uncertainty about drug composition and potency. In an effort to reduce overdoses, harm reduction organizations and health departments across the U.S. began distributing fentanyl test strips, a low barrier, inexpensive drug checking strategy. Studies show that people who use drugs (PWUD) frequently suspect that their drugs contain fentanyl and are interested in using fentanyl test strips to check their drugs; however, some people question their usefulness in regions where fentanyl presence is assumed. Understanding the utility of fentanyl test strips in fentanyl-saturated markets is a priority to best tailor interventions. Methods: In-depth interviews (N = 20) were conducted with individuals who reported recent (past 30 days) opioid use in Baltimore, MD. Results: Fentanyl was viewed as pervasive, dangerous, and difficult to avoid in the local drug supply. This dominant narrative characterized PWUD as disempowered by the heightened unpredictability of the drug market. While several strategies are used to navigate the drug market, respondents wanted more information about their drugs. In this context, fentanyl test strips were used in unique and unexpected ways to empower PWUD to be savvier market consumers, including avoiding fentanyl when there could be negative social or legal consequences, negotiating with dealers, and helping others in their social network navigate the opaque drug market. Conclusion: These findings add nuance and place fentanyl preference and use in the context of the drug market. When fentanyl presence is assumed, people used fentanyl test strips in unexpected ways to gain some control over their drug use. Novel uses for fentanyl test strips strengthen existing strategies used to navigate the drug market and mitigate overdose risk, and highlight their potential to quickly disseminate valuable information about the local drug supply.Diarrhea as a potential cause and consequence of reduced gut microbial diversity among undernourished children in peru

989-999AbstractBackground. Detrimental effects of diarrhea on child growth and survival are well documented, but details of the underlying mechanisms remain poorly understood. Recent evidence demonstrates that perturbations to normal development of the gut microbiota in early life may contribute to growth faltering and susceptibility to related childhood diseases. We assessed associations between diarrhea, gut microbiota configuration, and childhood growth in the Peruvian Amazon. Methods. Growth, diarrhea incidence, illness, pathogen infection, and antibiotic exposure were assessed monthly in a birth cohort of 271 children aged 0-24 months. Gut bacterial diversity and abundances of specific bacterial taxa were quantified by sequencing 16S rRNA genes in fecal samples collected at 6, 12, 18, and 24 months. Linear and generalized linear models were used to determine whether diarrhea was associated with altered microbiota and, in turn, if features of the microbiota were associated with the subsequent risk of diarrhea. Results. Diarrheal frequency, duration, and severity were negatively associated with bacterial diversity and richness (P < .05). Children born stunted (length-for-age z-score [LAZ] ≤ -2) who were also severely stunted (LAZ ≤ -3) at the time of sampling exhibited the greatest degree of diarrhea-associated reductions in bacterial diversity and the slowest recovery of bacterial diversity after episodes of diarrhea. Increased bacterial diversity was predictive of reduced subsequent diarrhea from age 6 to 18 months. Conclusions. Persistent, severe growth faltering may reduce the gut microbiota's resistance and resilience to diarrhea, leading to greater losses of diversity and longer recovery times. This phenotype, in turn, denotes an increased risk of future diarrheal disease and growth faltering.Gut microbiota features associated with campylobacter burden and postnatal linear growth deficits in a peruvian birth cohort

1000-1007AbstractBackground. Campylobacter infection is associated with impaired growth of children, even in the absence of symptoms. To examine the underlying mechanisms, we evaluated associations between Campylobacter infection, linear growth, and fecal microbial community features in a prospective birth cohort of 271 children with a high burden of diarrhea and stunting in the Amazonian lowlands of Peru. Methods. Campylobacter was identified using a broadly reactive, genus-specific enzyme-linked immunosorbent assay. 16S rRNAbased analyses were used to identify bacterial taxa in fecal samples at ages 6, 12, 18, and 24 months (N = 928). Associations between infection, growth, and gut microbial community composition were investigated using multiple linear regression adjusting for withinchild correlations, age, and breastfeeding. Indicator species analyses identified taxa specifically associated with Campylobacter burden. Results. Ninety-three percent (251) of children had Campylobacter present in asymptomatic fecal samples during the follow-up period. A 10% increase in the proportion of stools infected was associated with mean reductions of 0.02 length-for-age z scores (LAZ) at 3, 6, and 9 months thereafter (P < .01). We identified 13 bacterial taxa indicative of cumulative Campylobacter burden and 14 taxa significantly associated with high or low burden of enteroaggregative Escherichia coli, norovirus, or Giardia. Conclusions. Campylobacter infection is common in this cohort and associated with changes in microbial community composition. These results support the notion that disruptions to the fecal microbiota may help explain the observed effects of asymptomatic infections on growth in early life.High willingness to use overdose prevention sites among female sex workers in Baltimore, Maryland

212AbstractBackground: Overdose Prevention Sites (OPS) operate worldwide as spaces where people can consume previously purchased drugs under supervision, and are linked to reductions in HIV/HCV transmission and fatal overdoses. As the United States weighs their merits and legality, research is needed to estimate acceptability and use among populations at high risk for overdose. We examine willingness to use OPS among street-based female sex workers (FSW) with prevalent drug use and associated morbidities. Methods: We describe self-reported willingness, barriers and conditions around use of a hypothetical OPS among 141 FSW engaged in active drug use in Baltimore City, and describe trends using Pearson's χ2 and Fisher's exact tests. Results: Most women had history of overdose (55 %) and were likely to use OPS (77 %). Willingness was higher among women who: were sexual minorities (97 %;P=0.002),experienced homelessness (82 %;P=0.019), injected drugs (82 %;P=0.013), shared syringes (82 %;P=0.007), experienced sexual violence (92 %;P=0.045) or reported heroin use (83 %;P=0.039) in the past 3 months. Common anticipated barriers included transportation (45 %) and fear of arrest (41 %). Conclusions: This study highlights a population of uniquely high-risk women who would benefit from an OPS integrated with other services. Conditions and barriers discussed are informative for planning and implementation.Preventive malaria treatment among school-aged children in sub-Saharan Africa: a systematic review and meta-analyses

e1499-e1511AbstractBackground: The burden of malaria infection in sub-Saharan Africa among school-aged children aged 5–15 years is underappreciated and represents an important source of human-to-mosquito transmission of Plasmodium falciparum. Additional interventions are needed to control and eliminate malaria. We aimed to assess whether preventive treatment of malaria might be an effective means of reducing P falciparum infection and anaemia in school-aged children and lowering parasite transmission. Methods: In this systematic review and two meta-analyses, we searched the online databases PubMed, Embase, Cochrane CENTRAL, and Clinicaltrials.gov for intervention studies published between Jan 1, 1990, and Dec 14, 2018. We included randomised studies that assessed the effect of antimalarial treatment among asymptomatic school-aged children aged 5–15 years in sub-Saharan Africa on prevalence of P falciparum infection and anaemia, clinical malaria, and cognitive function. We first extracted data for a study-level meta-analysis, then contacted research groups to request data for an individual participant data meta-analysis. Outcomes of interest included prevalence of P falciparum infection detected by microscopy, anaemia (study defined values or haemoglobin less than age-adjusted and sex-adjusted values), clinical malaria (infection and symptoms on the basis of study-specific definitions) during follow-up, and code transmission test scores. We assessed effects by treatment type and duration of time protected, and explored effect modification by transmission setting. For study-level meta-analysis, we calculated risk ratios for binary outcomes and standardised mean differences for continuous outcomes and pooled outcomes using fixed-effect and random-effects models. We used a hierarchical generalised linear model for meta-analysis of individual participant data. This study is registered with PROSPERO, CRD42016030197. Findings: Of 628 studies identified, 13 were eligible for the study-level meta-analysis (n=16 309). Researchers from 11 studies contributed data on at least one outcome (n=15 658) for an individual participant data meta-analysis. Interventions and study designs were highly heterogeneous; overall risk of bias was low. In the study-level meta-analysis, treatment was associated with reductions in P falciparum prevalence (risk ratio [RR] 0·27, 95% CI 0·17–0·44), anaemia (0·77, 0·65–0·91), and clinical malaria (0·40, 0·28–0·56); results for cognitive outcomes are not presented because data were only available for three trials. In our individual participant data meta-analysis, we found treatment significantly decreased P falciparum prevalence (adjusted RR [ARR] 0·46, 95% CI 0·40–0·53; p<0·0001; 15 648 individuals; 11 studies), anaemia (ARR 0·85, 0·77–0·92; p<0·0001; 15 026 individuals; 11 studies), and subsequent clinical malaria (ARR 0·50, 0·39–0·60; p<0·0001; 1815 individuals; four studies) across transmission settings. We detected a marginal effect on cognitive function in children older than 10 years (adjusted mean difference in standardised test scores 0·36, 0·01–0·71; p=0·044; 3962 individuals; five studies) although we found no significant effect when combined across all ages. Interpretation: Preventive treatment of malaria among school-aged children significantly decreases P falciparum prevalence, anaemia, and risk of subsequent clinical malaria across transmission settings. Policy makers and programme managers should consider preventive treatment of malaria to protect this age group and advance the goal of malaria elimination, while weighing these benefits against potential risks of chemoprevention.

700-746AbstractPolicy Points This article reconceptualizes our understanding of the opioid epidemic and proposes six strategies that address the epidemic's social roots. In order to successfully reduce drug-related mortality over the long term, policymakers and public health leaders should develop partnerships with people who use drugs, incorporate harm reduction interventions, and reverse decades of drug criminalization policies. Context: Drug overdose is the leading cause of injury-related death in the United States. Synthetic opioids, predominantly illicit fentanyl and its analogs, surpassed prescription opioids and heroin in associated mortality rates in 2016. Unfortunately, interventions fail to fully address the current wave of the opioid epidemic and often omit the voices of people with lived experiences regarding drug use. Every overdose death is a culmination of a long series of policy failures and lost opportunities for harm reduction. Methods: In this article, we conducted a scoping review of the opioid literature to propose a novel framework designed to foreground social determinants more directly into our understanding of this national emergency. The “continuum of overdose risk” framework is our synthesis of the global evidence base and is grounded in contemporary theories, models, and policies that have been successfully applied both domestically and internationally. Findings: De-escalating overdose risk in the long term will require scaling up innovative and comprehensive solutions that have been designed through partnerships with people who use drugs and are rooted in harm reduction. Conclusions: Without recognizing the full drug-use continuum and the role of social determinants, the current responses to drug overdose will continue to aggravate the problem they are trying to solve.The development of the Police Practices Scale: Understanding policing approaches towards street-based female sex workers in a U.S. City

1AbstractPolicing is an important structural determinant of HIV and other health risks faced by vulnerable populations, including people who sell sex and use drugs, though the role of routine police encounters is not well understood. Given the influence of policing on the risk environment of these groups, methods of measuring the aggregate impact of routine policing practices are urgently required. We developed and validated a novel, brief scale to measure police patrol practices (Police Practices Scale, PPS) among 250 street-based female sex workers (FSW) in Baltimore, Maryland, an urban setting with high levels of illegal drug activity. PPS items were developed from existing theory and ethnography with police and their encounters with FSW, and measured frequency of recent (past 3 months) police encounters. The 6-item scale was developed using exploratory factor analysis after examining the properties of the original 11 items. Confirmatory factor analysis was used to model the factor structure. A 2-factor model emerged, with law enforcement PPS items and police assistance PPS items loading on separate factors. Linear regression models were used to explore the relative distribution of these police encounters among FSW by modeling association with key socio-demographic and behavioral characteristics of the sample. Higher exposure to policing was observed among FSW who were homeless (β = 0.71, p = 0.037), in daily sex work (β = 1.32, p = 0.026), arrested in the past 12 months (β = 1.44, p<0.001) or injecting drugs in the past 3 months (β = 1.04, p<0.001). The PPS provides an important and novel contribution in measuring aggregate exposure to routine policing, though further validation is required. This scale could be used to evaluate the impact of policing on vulnerable populations' health outcomes, including HIV risk.Trends in opioid initiation among people who use opioids in three US cities

375-383AbstractIntroduction and Aims: The increased availability of prescription opioids (PO) and non-medical prescription opioids (NMPO) has fundamentally altered drug markets and typical trajectories from initiation to high-risk use among people who use opioids (PWUO). This multi-site study explores trends in opioid initiation in three US cities and associations with sociodemographic factors, current drug use and overdose risk. Design and Methods: We analysed survey data from a cross-sectional study of PWUO in Baltimore, Maryland (n = 173), Boston, Massachusetts (n = 80) and Providence, Rhode Island (n = 75). Age of first exposure to PO, NMPO and heroin was used to calculate opioid of initiation, and multinomial regression was employed to explore correlates of initiating with each. Results: Thirty-three percent of PWUO initiated with heroin, 24% with PO, 18% with NMPO and 24% with multiple opioids in their first year of use. We observed a reduction in heroin initiation and gradual replacement with PO/NMPO over time. Women were more likely to initiate with NMPO [relative risk ratio (RRR) 2.4; 95% confidence interval (CI) 1.1, 5.0], PO (RRR 2.2, 95% CI 1.1, 4.4) or multiple opioids (RRR 2.1, 95% CI 1.1, 4.2), than heroin. PWUO initiating with NMPO had significantly higher current benzodiazepine use, relative to those initiating with heroin (RRR 3.2, 95% CI 1.4, 7.4), and a high prevalence of current fentanyl use (30%). Discussion and Conclusions: Our study highlights women and PWUO initiating with NMPO as key risk groups amid the changing landscape of opioid use and overdose, and discusses implications for targeted prevention and treatment.Harm reduction measures employed by people using opioids with suspected fentanyl exposure in Boston, Baltimore, and Providence

1AbstractBackground: Exposure to potent synthetic opioids such as illicitly manufactured fentanyl (IMF) has fueled the escalating overdose crisis in the USA, particularly in the east coast. Drug checking services, which allow people who use drugs (PWUD) to learn about the contents of their drugs, remain limited and even criminalized in many states. Further, there is a persistent belief that PWUD are not willing or able to change their behaviors despite being aware of their potential exposure to fentanyl through drug use. Methods: We conducted a multi-site cross-sectional study among PWUD to assess what behaviors, if any, were employed in the case of suspected fentanyl exposure, and the correlates of engaging in harm reduction behaviors (HRB). PWUD (N = 334) were recruited in Boston (n = 80), Providence (n = 79), and in Baltimore (n = 175). At the time of the survey, no legal drug checking services were available in these cities. Results: The majority of PWUD (84%) expressed concern about fentanyl. Among those who suspected fentanyl exposure prior to using their drugs (n = 196), 39% reported employing HRB including using less of the drug (12%) or abstaining altogether (10%), using more slowly (5%), and doing a tester shot (5%). In adjusted logistic regression models, the odds (aOR) of practicing HRB after suspecting fentanyl exposure were increased among PWUD who were non-White (aOR 2.1; p = 0.004) and older (aOR 1.52 per decade of age; p < 0.001). Daily injection (aOR 0.50; p < 0.001), using drugs in public (aOR 0.58; p = 0.001), using drugs alone (aOR 0.68; p < 0.001), and experiencing multiple recent overdoses (aOR 0.55; p < 0.001) were associated with decreased odds of practicing HRB. Conclusions: These data illustrate that PWUD employ a number of practices to reduce overdose risk in a context of unknown drug purity and content. Results may also guide efforts to identify early adopters of drug checking services and engage them in peer-outreach to target the most socially and structurally vulnerable PWUD, who are not reporting behavior change, with harm reduction messaging.Police attitudes towards pre-booking diversion in Baltimore, Maryland

78-85AbstractBackground: In the context of high rates of drug-related incarceration that disproportionately affect urban communities of colour, advocates for drug policy criminal justice reform have called for alternatives to mass incarceration. The Law Enforcement Assisted Diversion (LEAD) program redirects low-level drug offenders to health and social services rather than immediately into the criminal justice system. In advance of piloting LEAD in Baltimore City, we assessed police perceptions towards harm reduction and specifically pre-booking diversion in effort to inform training and implementation activities in Baltimore City and elsewhere. Methods: We administered a survey to Baltimore City Police Officers (N = 83) in the planned implementation district using two scales: the first measured police attitudes toward people who use drugs (PWUD), current drug policies and public health measures, and the second measured police perceptions of pre-booking diversion programs. We calculated Cronbach's alpha (α) to assess internal consistency of both scales. Bivariate χ 2 tests and multivariate logistic regression examined correlates of scale items stratified by new and seasoned officers. Results: Seasoned officers were significantly less likely to believe that drug treatment is easily available (51% vs. 81%, p = 0.005). The belief that current policies are effective and that PWUD should be arrested for small drug purchases decreased significantly per year on the force (aOR: 0.92; 95%CI 0.85,0.99; aOR: 0.94, 95% CI 0.88, 0.99, respectively), as did concerns about needle-stick injuries (aOR: 0.85, 95% CI 0.74, 0.98). Seasoned officers were significantly more comfortable referring PWUD to social services (100% vs. 83%, p = 0.006), and agree that such pre-booking diversion could be effective in improving public safety within (72% vs. 43%; p = 0.009) and beyond the intervention area (56% vs. 33%, p = 0.04). Conclusions: The study indicates the value of intervening early and consistently throughout police career trajectories and engaging seasoned officers as allies to promote recognition and support of public health and harm reduction strategies within ongoing police reform efforts. LEAD provides important and broad opportunities for training police to enhance their understanding the intersection of public safety and public health.Preference for drugs containing fentanyl from a cross-sectional survey of people who use illicit opioids in three United States cities

204AbstractBackground: Death from fentanyl-related overdose is now a leading cause of mortality among US adults. We sought to characterize fentanyl preference among street-based people who use drugs (PWUD). Methods: Cross-sectional surveys were administered to PWUD (N = 308) who illicitly used heroin or prescription opioids in the prior six months. Recruitment occurred in 2017 in three US east coast cities with high overdose mortality: Baltimore, Boston, and Providence. Our main outcome was preference for fentanyl (yes/no); exposures included sociodemographics, drug use, and overdose history. Pearson's χ2, Shapiro-Wilk-Mann rank-sum tests, and tiered log-binomial regression determined sociodemographic and exposure-related factors associated with fentanyl preference. Results: Preference for nonmedical use of fentanyl was reported by 27% (n = 83) of the sample. Fentanyl preference was associated with non-Hispanic white race (adjusted risk ratio (ARR) = 1.68, 95% confidence interval (CI):1.18–2.40), daily illicit drug use (aRR = 2.2, CI:1.71–2.87), and overdose ≥1 year ago (aRR = 1.33, CI:1.18–1.50). Age (in decades; aRR = 0.77, CI:0.61–0.98) and overdose <1 year ago (aRR = 0.92, CI:0.87–0.97) were associated with a decreased likelihood of preference. In our model excluding sociodemographics, initiating opioid use with non-prescribed opioids was associated with fentanyl preference (aRR = 1.48, CI:1.26-1.73). Conclusion: In three cities with high levels of opioid use and overdose, a quarter of street based PWUD reported preferring fentanyl. An opioid use age cohort effect and disproportionate access to prescription opioids by race could be contributing to preference. Frequency of opioid use, not route of administration, was associated with preference. Our data demonstrate the need to consider preferences for fentanyl when targeting services and interventions for PWUD.
