Professional overview

Dr. Stephanie Cook’s overarching research focus is to understand how structural- and individual-level minority stressors contribute to mental health, physical health, and health behaviors across the life span. Further, she seeks to understand how features of close relationships can exacerbate or buffer the negative effects of minority stress on health. Her work primarily focuses on young adults transitioning to adulthood who are at the intersection of racial/ethnic and sexual orientation status. In addition, much of her current work examines the links between minority stress (i.e., daily experiences of discrimination) and biological markers of stress (e.g. cortisol and c-reactive protein).

Dr. Cook’s substantive methodological and statistical focus is in the development and application of longitudinal study designs (i.e., intensive longitudinal designs) for determining the ways in which dynamic changes in features of minority stress (e.g., daily and momentary discrimination events) are associated with changes in risk behaviors and physical health (e.g., sexual risk and substance use, pre-clinical cardiovascular disease, and biological stress) among racial/ethnic and/or sexual minority young adults. 

Dr. Cook is the Director of the Attachment and Health Disparities Research Lab (AHDL) which is currently made up of about 20 undergraduate, graduate, and postdoctoral fellows. She I developed an integrated theory of adult attachment (the Integrated Attachment and Sexual Minority Stress Model [IASMS]; i.e., the development, or lack, of strong socio-emotional bonds) and minority stress (i.e., social stress experienced by individuals in minority social groups) as a means to better understand and address the health needs of disadvantaged youth transitioning to adulthood. Dr. Cook and her team’s long-term goal is to continue creating, implementing, and refining sustainable interventions to reduce the influence of stress on health utilizing innovative methodologies.

Abstract
Abstract
Background: Young sexual and gender minorities (SGMs) of color may face unique experiences of discrimination based on their intersectional positions (eg, discrimination based on both racial or ethnic identity and sexual identity). Emerging evidence suggests that mindfulness practices may reduce stress from discrimination and improve overall well-being among young SGM. Moreover, the omnipresence of smartphone access among racial or ethnic and sexual minority communities provides a method through which to administer mindfulness-based interventions among young SGMs of color. Objective: This paper outlines the protocol of the Optimizing a Daily Mindfulness Intervention to Reduce Stress from Discrimination among Young Sexual and Gender Minorities of Color (REDUCE) study, a pilot optimization trial of a smartphone-based mindfulness intervention that was developed in conjunction with the Healthy Minds Program (HMP) with the aim of reducing stress from discrimination among young SGMs. Methods: In total, 80 young (ages 18-29 years) SGMs of color will be enrolled in the study. The HMP is a self-guided meditation practice, and participants will be randomized to either a control condition or an intervention that uses a neuroscience-based approach to mindfulness. We will use the multiphase optimization strategy to assess which combination of mindfulness interventions is the most effective at reducing stress from discrimination among young SGMs of color. A combination of mindfulness-based meditation intervention components will be examined, comprising mindfulness-based practices of awareness, connection, and purpose. Awareness refers to the practice of self-Awareness, which reduces the mind s ability to be distracted and instead be present in the moment. Connection refers to the practice of connection with oneself and others and emphasizes on empathy and compassion with oneself and others. Purpose encourages goal-making in accordance with one s values and management of behavior in accordance with these goals. In addition, we will assess the feasibility and acceptability of the HMP application among young SGMs of color. Results: The REDUCE study was approved by the Institutional Review Board of New York University, and recruitment and enrollment began in the winter of 2021. We expect to complete enrollment by the summer of 2022. The results will be disseminated via social media, journal articles, abstracts, or presentations, as well as to participants, who will be given the opportunity to provide feedback to the researchers. Conclusions: This optimization trial is designed to test the efficacy, feasibility, and acceptability of implementing an application-based, mindfulness-based intervention to reduce stress from discrimination and improve well-being among young SGMs of color. Evidence from this study will assist in the creation of a sustainable, culturally relevant mobile app based mindfulness intervention to reduce stress from discrimination among young SGMs of color.

Abstract
Uric acid levels during pregnancy have been examined as a potential indicator of risk for gestational diabetes mellites, hypertension, and related adverse birth outcomes. However, evidence supporting the utility of serum uric acid levels in predicting poor maternal and fetal health has been mixed. The lack of consistent findings may be due to limitations inherent in serum-based biomeasure evaluations, such as minimal repeated assessments and variability in the timing of these assessments. To address these gaps, we examined repeated measurements of diurnal salivary uric acid (sUA) levels in a sample of 44 healthy women across early-mid and late pregnancy. We assessed potential covariates and confounds of sUA levels and diurnal trajectories, as well as associations between maternal weight gain and blood pressure during pregnancy and sUA concentrations. Using multilevel linear models, we found sUA increased across pregnancy and displayed a robust diurnal pattern with the highest concentrations at waking, a steep decline in the early morning, and decreasing levels across the day. Maternal pre-pregnancy BMI, age, prior-night sleep duration, and fetal sex were associated with sUA levels and/or diurnal slopes. Maternal blood pressure and gestational weight gain also showed significant associations with sUA levels across pregnancy. Our results expand upon those found with serum UA measurements. Further, they demonstrate the feasibility of using at-home, minimally-invasive saliva sampling procedures to track UA levels across pregnancy with potential applications for the long-term monitoring of maternal cardiometabolic risk.

Abstract
This report examines associations between everyday discrimination, microaggressions, and CRP to gain insight on potential mechanisms that may underlie increased CVD risk among sexual minority male young adults. The sample consisted of 60 participants taken from the P18 cohort between the ages of 24 and 28 years. Multinomial logistic regression models were used to examine the association between perceived everyday discrimination and LGBQ microaggressions with C-reactive protein cardiovascular risk categories of low-, average-, and high-risk, as defined by the American Heart Association and Centers for Disease Control. Adjustments were made for BMI. Individuals who experienced more everyday discrimination had a higher risk of being classified in the high-risk CRP group compared to the low-risk CRP group (RRR = 3.35, p = 0.02). Interpersonal LGBQ microaggressions were not associated with CRP risk category. Everyday discrimination, but not specific microaggressions based on sexual orientation, were associated with elevated levels of CRP among young sexual minority men (YSMM). Thus, to implement culturally and age-appropriate interventions, further researcher is needed to critically examine the specific types of discrimination and the resultant impact on YSMM’s health.

Abstract
Background: African countries have the highest number of people living with HIV (PWH). The continent is home to 12% of the global population, but accounts for 71% of PWH globally. Antiretroviral therapy has played an important role in the reduction of the morbidity and mortality rates for HIV, which necessitates increased surveillance of the threats from pernicious risks to which PWH who live longer remain exposed. This includes cardiopulmonary comorbidities, which pose significant public health and economic challenges. A significant contributor to the cardiopulmonary comorbidities is tobacco smoking. Indeed, globally, PWH have a 2–4-fold higher utilization of tobacco compared to the general population, leading to endothelial dysfunction and atherogenesis that result in cardiopulmonary diseases, such as chronic obstructive pulmonary disease and coronary artery disease. In the context of PWH, we discuss (1) the current trends in cigarette smoking and (2) the lack of geographically relevant data on the cardiopulmonary conditions associated with smoking; we then review (3) the current evidence on chronic inflammation induced by smoking and the potential pathways for cardiopulmonary disease and (4) the multifactorial nature of the syndemic of smoking, HIV, and cardiopulmonary diseases. This commentary calls for a major, multi-setting cohort study using a syndemics framework to assess cardiopulmonary disease outcomes among PWH who smoke. Conclusion: We call for a parallel program of implementation research to promote the adoption of evidence-based interventions, which could improve health outcomes for PWH with cardiopulmonary diseases and address the health inequities experienced by PWH in African countries.

Abstract
The use of broad consent to store human biospecimens to be used in future research studies has increased over the years. However, it is currently unknown how young sexual minority men (YSMM) perceive broad consent in these specific types of studies. Therefore, in this study we aimed to determine the extent to which YSMM are comfortable with providing broad consent concerning their identifiable biological specimens to a variety of entities, including external researchers and pharmaceutical companies and to examine the relationship between mistrust based on racial/ethnic identity or sexual orientation and attitudes toward broad consent. YSMM (N = 239) ages 24–27 years were recruited from a prospective cohort study in New York City in 2018 to complete a survey assessing attitudes about the use of broad consent concerning biospecimens for secondary research. We found that YSMM were most willing to provide broad consent to the researcher from the study they were enrolled in (85.3%), other researchers within the same university (82.4%), and researchers at other universities (74.5%). Participants were least willing to provide broad consent to government organizations (64.4%) and pharmaceutical companies (53.8%). Further, we found that medical mistrust based on racial/ethnic identity or sexual orientation was associated with attitudes toward the use of broad consent. Research institutions should consider modifying consent procedures around the use of broad consent in order to maximize recruitment and retention, especially among minority populations.

Abstract
Abstract
Previous research has used cortisol, the major hormonal byproduct of the hypothalamic pituitary adrenal (HPA) axis system, to explore how environmental stressors influence daily physiological functioning. Most of the research focused on diurnal cortisol has examined specific cortisol markers, with little consideration of how different components of the diurnal pattern may co-occur. Morning level, cortisol awakening response (CAR), bedtime level, as well as the diurnal slope and total cortisol exposure throughout the day (area under the curve; AUC), are five common parameters of diurnal HPA axis functioning that have been individually linked to physical and mental health outcomes, with mixed results. The current study introduces a novel approach to capture heterogeneity in HPA axis activity by using latent profile analysis to generate empirically-derived, theoretically supported diurnal cortisol profiles based on all five indicators. We analyzed salivary cortisol data from 278 young adults during a time of heightened sociopolitical stress – the 2016 U.S. presidential election – and examined whether profiles differentially predicted mental health trajectories across six months. Findings suggest that a specific combination of cortisol parameters (i.e., flat slope, high AUC, and high CAR) may predict worse mental health risk over time. Overall, this work suggests that diurnal cortisol profiles likely reflect distinct physiological underpinnings with unique health consequences that may not be observed by studying individual cortisol parameters.

Abstract
This study assessed the modifying role of primary source of COVID-19 information in the association between knowledge and protective behaviors related to COVID-19 among adults living in the United States (US). Data was collected from 6,518 US adults through an online cross-sectional self-administered survey via social media platforms in April 2020. Linear regression was performed on COVID-19 knowledge and behavior scores, adjusted for sociodemographic factors. An interaction term between knowledge score and primary information source was included to observe effect modification by primary information source. Higher levels of knowledge were associated with increased self-reported engagement with protective behaviors against COVID-19. The primary information source significantly moderated the association between knowledge and behavior, and analyses of simple slopes revealed significant differences by primary information source. This study shows the important role of COVID-19 information sources in affecting people's engagement in recommended protective behaviors. Governments and health agencies should monitor the use of various information sources to effectively engage the public and translate knowledge into behavior change during an evolving public health crisis like COVID-19.

Abstract
The application of group-based trajectory analysis with a zero-inflation specification to understand adaptations in alcohol and marijuana use among sexual minorities during the emerging adulthood period is underutilized. We propose a series of four steps in the application of group-based trajectory analysis for outcomes that follow a zero-inflated distribution. In addition, using a longitudinal cohort study of emerging adult sexual minority men (n = 597) we provide an example of how to obtain group-based trajectory profiles of alcohol and marijuana use among emerging adult sexual minority men with a zeroinflated specification. In addition, we examined racial/ethnic differences in trajectory profiles. Findings suggest that there were five distinct alcohol and marijuana use trajectories that were reliably predicted by racial/ethnic identity for alcohol but not marijuana utilizing the zero-inflated specification. A summary of findings and concluding remarks related to the utility of this modeling technique are presented.

Abstract
Abstract
Background: Exposure to sexual orientation-related discrimination among sexual minorities may lead to elevated levels of C-reactive protein (CRP) as compared to their heterosexual counterparts. However, little is known about factors that may buffer the association between discrimination and CRP among sexual minorities versus heterosexuals. The current study examined if the association between discrimination, sexual orientation, and CRP differed across levels of social support from one's father/father-figure or mother/mother-figure between sexual minorities and heterosexuals. Methods: Data came from Wave IV of the National Longitudinal Study of Adolescent to Adult Health (Add Health). The sample sizes for father support and mother support was 3167 and 3575, respectively. Participants ranged in age from 24 to 33 years. Stratified linear regression models examined if father and mother support moderated the association between discrimination and CRP among sexual minorities and heterosexuals. Results: Father support significantly moderated the association between discrimination and CRP among sexual minorities but not heterosexuals. Sexual minorities with higher father support and who experienced discrimination had lower CRP as compared to those with lower father support and who experienced discrimination. Mother support did not moderate the association between discrimination and CRP among either sexual minorities or heterosexuals. Conclusion: Father support may mitigate the negative effects of stress from discrimination on CRP among sexual minorities. Future research should further examine the potential differential role that father support may play in reducing cardiovascular risk among sexual minorities versus heterosexuals who experience discrimination.

Abstract
We seek to move beyond a deficits-based approach, which has dominated our understanding of health and wellbeing in in young sexual minority males (YSMM), by examining how indicators of positive development are associated with development of positive self-rated health in YSMM. Using data from a prospective cohort study of YSMM (n = 514; 18–22 years old; 36.9% Hispanic/Latino, 15.6% non-Hispanic Black, 30.2% White, 16.9% other/multi-racial), we examined how three measures of positive development–the Life Orientation Test, the Satisfaction with Life Scale (SWLS) and the Social Responsibility Scale (SRS) were associated with self-rated health (SRH), a valid and reliable measure of self-assessed general health status. Findings suggest that YSMM who self-identified as homosexual reported higher SRH while those who reported higher levels of substance use and mental health burdens reported lower SRH. Second, in linear growth models controlling for mental health burdens and substance use, higher scores on all measures of positive development were associated with higher ratings of SRH over time. In conclusion, the presence of positive development characteristics, specifically generalized optimism, life satisfaction and social responsibility, may buffer against negative SRH assessments. Health promotion programs focusing on positive development may more effectively promote health and well-being among YSMM.

Abstract
Objectives: Attachment insecurity may be more pronounced among young gay and bisexual men (YGBM). Further, attachment insecurity is associated with dysregulated patterns of emotion regulation, which can lead to depression. However, pathways linking attachment insecurity to depression are underexplored among YGBM. Methods: This study used pilot data from N = 67 YGBM to examine if emotion dysregulation mediated the association between attachment insecurity and depression. Results: Results supported the study hypotheses. Attachment insecurity was associated with emotion dysregulation, which was associated with depression. Conclusion: Findings provide preliminary evidence that emotion regulation training may be a useful approach for addressing depression among YGBM.

Abstract
We conducted a mixed-methods study to identify factors that influence transitions in attachment style between childhood and adulthood among 28 young Black gay and bisexual men (YBGBM) in the United States. We used a phenomenological approach to data integration, with the major component to the results being garnered from the qualitative interviews. We organized our results by four attachment transition groups: stable secure (secure attachment in childhood and young adulthood), stable insecure (insecure attachment in childhood and young adulthood), secure to insecure (secure in childhood and insecure in adulthood) and insecure to secure (insecure in childhood and secure in adulthood). Within each of the typologies, two major themes emerged: social support and religion. Generally, transitions from secure to insecure attachment were related to experiences of perceived rejection by a parental figure during adolescence that corresponded with sexual orientation disclosure. Transitions from insecure to secure attachment appeared to be related to the absence of an attachment figure early in life, but with the acquisition of an attachment figure during early to late adolescence. The findings from our study suggest a need for attachment-based approaches to social support interventions, as well as for an increased understanding of social and cultural factors that impact attachment changes among practitioners who use attachment-based therapy models for YBGBM.

Abstract
Exposure to violence during adolescence is associated with increased risk behaviors and mental health problems in adulthood. Friendship attachment during adolescence may, however, mitigate the negative effects of exposure to violence on trajectories of depression and anxiety in young adulthood. In this study, we used growth curve modeling to examine associations between exposure to violence and mental health outcomes, followed by multi-group analyses with friendship attachment as the moderator. The sample was drawn from a longitudinal study (12 waves; 1994–2012) of 676 (54% female) urban high school students. We found strong positive associations between exposure to violence during adolescence and later self-reported depressive and anxiety symptoms. Notably, securely attached adolescents reported faster decreases in mental health symptoms as a function of violence relative to their insecurely attached peers as they transitioned into adulthood.

Abstract
Objective: Sexual minority men (SMM) in the United States continue to experience adverse health problems and psychosocial burdens. However, there is limited psychometric research seeking to quantify the life worries of this population. Informed by syndemic theory, the Life Worries Scale (LWS) was developed to measure the concerns of young SMM. Method: Analyses of the scale were undertaken using baseline data (n = 665) from an ongoing cohort study of emerging adult, SMM. Results: Exploratory factor analyses (EFA) of an initial set of 24 Likert-type items, followed by confirmatory factor analysis (CFA) and an exploratory structural equation model (ESEM), indicated a structure consisting of 6 domains of worries: financial stability, social stability, self esteem, loneliness, physical appearance, and physical health. These 6 subscales were highly correlated and also demonstrated high levels of internal consistency. Differences in life worries were noted across demographic states, specifically HIV serostatus, sexual attraction, housing status, and self-rated health. High levels of association were also detected between all 6 subscales with both depression and PTSD, while significant correlations were detected between suicidality and both self esteem and loneliness related worries. Conclusions: The results of our analyses provide evidence for the strong psychometric characteristics of the LWS. This newly developed instrument should be utilized in research to examine the extent to which life worries explain health outcomes and risk behaviors in sexual minority males, and may be potentially extended for use in other populations.

Abstract
This study examines how romantic relationship cognitions are associated with changes of condomless anal sex among emerging adult gay and bisexual men. The sample was drawn from four waves of a prospective cohort study (N = 598; M age = 18.2). Results suggest that condomless anal sex increased over the emerging adulthood period. Romantic relationship fear was associated with increased receptive condomless anal sex. Perceptions of greater romantic relationship control increased the likelihood of having insertive and receptive condomless anal sex. Findings suggest that romantic relationship cognitions are important to consider when understanding longitudinal changes in condomless anal sex in this population.

Abstract
Early experiences with parents may be particularly difficult for lesbian, gay and bisexual (LGB) individuals who face stigma that is linked to potentially distinct stress-related biobehavioural profiles. This study examined the association between parental bonding in relation to acute stress (cortisol reactivity) and chronic stress (allostatic load) in LGB and heterosexual individuals. The sample consisted of 87 healthy adults (mean [SD] age = 24.6 [0.6] years; LGB: n = 46, 43% women; and heterosexual n = 41, 49% women). Regressions tested the main effects of retrospectively assessed parental overprotection and care before the age of 16 on stress reactive cortisol (area under the curve) and allostatic load (indexed using 21 neuroendocrine, immune, metabolic and cardiovascular biomarkers), and whether sexual orientation status moderated this association. Results revealed that parental overprotection was associated with increased cortisol reactivity only for LGB participants, but not for heterosexual participants. By contrast, parental overprotection was associated with higher allostatic load only for heterosexual participants, but not for LGB participants. While the functional significance of this requires further study, these preliminary findings suggest that adaptive processes among LGB individuals may mitigate the negative effects of parental overprotection on markers of chronic stress.

Abstract
Objective: The objective of this study was to examine the association between perceived stress and sleep health among a sample of sexual minority men (SMM). Design: Cross-sectional survey. Setting: Paris, France. Participants: Gay, bisexual and other SMM users ≥18 years on a geosocial networking application in Paris, France (N = 580). Measurements: Participants were directed to a web-based survey measuring stress, sleep health, and socio-demographics. Multivariate log-binomial regression models were used to estimate the adjusted risk ratios (aRRs) and 95% confidence intervals (CIs) to examine how stress may affect different dimensions of sleep health: 1) poor sleep quality, 2) short sleep duration, 3) problems falling asleep, and 4) problems staying awake in the daytime. Results: Most participants (69.9%) reported at least sometimes feeling stressed (compared to never or rarely). Additionally, results demonstrate that higher perceived stress was associated with poorer sleep health; compared with those who reported feeling stress never or rarely, those who felt stress sometimes, often, or always were more likely to experience poor sleep quality (aRR = 6.67; 95% CI = 3.61–12.3), short sleep duration (aRR = 1.67; 95% CI = 1.17–2.38), problems falling asleep (aRR = 3.20; 95% CI = 2.26–4.52), and problems staying awake during the daytime (aRR = 3.52; 95% CI = 1.64–7.53). Conclusion: Elevated perceived stress can negatively influence sleep health among SMM in Paris, France.

Abstract
This study explored the extent to which private regard and religiosity beliefs serve as protective factors for school bonding among African American and Caribbean black adolescents who experience racial discrimination in school. Findings are drawn from a nationally representative sample of (n = 810) African American and (n = 360) Caribbean black adolescents (52% girls) aged 13–17 (Mage = 15, SD = 1.42) years.

For African American adolescents, perceiving more racial discrimination from teachers and reporting lower private regard beliefs was associated with less school bonding. The findings for Caribbean black adolescents revealed that endorsing moderate levels of religiosity and perceiving higher rates of teacher discrimination was associated with less school bonding. The developmental significance and implications for future research are discussed.
