Associate Professor of Social & Behavioral Sciences and Epidemiology

Dr. Mari Armstrong-Hough is Associate Professor in the Department of Social & Behavioral Sciences and in the Department of Epidemiology. She is a medical sociologist and epidemiologist of respiratory disease.

Dr. Armstrong-Hough’s global health research examines the epidemiologic interfaces among tuberculosis (TB), HIV, and non-communicable diseases. Combining training in epidemiology and sociology, her work develops and evaluates interventions to increase early case-finding, status awareness, and linkage to care in high-burden settings like Uganda and South Africa. She has published on predictors of evaluation for TB among high-risk groups, novel approaches to active case-finding for TB and HIV, the ways that providers and patients imagine and communicate risk for respiratory infection, and the availability of essential medicines in settings with double burdens of infectious and non-communicable disease. Her first book, Biomedicalization and the Practice of Culture: Globalization and Type 2 Diabetes in the United States and Japan (University of North Carolina Press, 2018), examined how the practice and experience of global evidence-based medicine is shaped by local cultural repertoires. Her recent work has appeared in the Journal of AIDS, International Journal of Tuberculosis and Lung Disease, and the The Lancet Respiratory Medicine. She also co-directs the NIH-funded Mixed-Methods Fellowship of the Pulmonary Complications of AIDS Research Training Program at Makerere University in Kampala, Uganda. She is PI of a prospective cohort study of patients initiating treatment for pulmonary TB in Uganda and a co-investigator on NIH-funded studies of contact tracing for TB.

Dr. Armstrong-Hough’s US-based research examines racial and ethnic disparities in survival of respiratory failure and seeks to develop interventions to ensure that all patients with respiratory failure receive evidence-based care. Approximately 750,000 Americans die each year from respiratory failure, and its 2.5 million survivors experience poor physical function and quality of life persisting five years after discharge. Minority patients are significantly less likely to survive respiratory failure, with up to twice the odds of death as non-Hispanic White patients. Dr. Armstrong-Hough co-PIs the Promoting Equity via Changes In Practice for Respiratory Failure (PRECIPICE) studies, which use large-scale, multicenter data from US ICUs to identify care processes associated with inequities in survival and long-term outcomes. Early work related to these studies has been accepted to Annals of the American Thoracic Society.

Before coming to NYU, Dr. Armstrong-Hough was an Associate Research Scientist in Epidemiology in the Department of Epidemiology of Microbial Diseases at Yale School of Public Health. She previously taught at Davidson College, Meiji University in Tokyo, and Duke University. She has conducted fieldwork in the United States, Japan, Uganda, Ethiopia, and Nepal and is a recipient of the Robert E. Leet and Clara Guthrie Patterson Trust Mentored Research Award in Clinical, Health Services and Policy Research.

Abstract

Abstract

Background: Smoking rates remain high in Vietnam, particularly among people living with HIV/AIDS (PLWH), but tobacco cessation services are not available in outpatient HIV clinics (OPCs). The research team is conducting a type II hybrid randomized controlled trial (RCT) comparing the cost-effectiveness of three tobacco cessation interventions among PLWH receiving care in HIV clinics in Vietnam. The study is simultaneously evaluating the implementation processes and outcomes of strategies aimed at increasing the implementation of tobacco dependence treatment (TDT) in the context of HIV care. This paper describes the systematic, theory-driven process of adapting intervention components and implementation strategies with demonstrated effectiveness in high-income countries, and more recently in Vietnam, to a new population (i.e., PLWH) and new clinical setting, prior to launching the trial. Methods: Data collection and analyses were guided by two implementation science frameworks and the socio-ecological model. Qualitative interviews were conducted with 13 health care providers and 24 patients in three OPCs. Workflow analyses were conducted in each OPC. Qualitative data were analyzed using rapid qualitative analysis procedures. Based on findings, components of the intervention and implementation strategies were adapted, followed by a 3-month pilot study in one OPC with 16 patients randomized to one of two intervention arms. Results: The primary adaptations included modifying the TDT intervention counseling content to address barriers to quitting among PLWH and Vietnamese sociocultural norms that support smoking cessation. Implementation strategies (i.e., training and system changes) were adapted to respond to provider- and clinic-level determinants of implementation effectiveness (e.g., knowledge gaps, OPC resource constraints, staffing structure, compatibility). Conclusions: Adaptations were facilitated through a mixed method, stakeholder (patient and health care provider, district health leader)-engaged evaluation of context-specific influences on intervention and implementation effectiveness. This data-driven approach to refining and adapting components aimed to optimize intervention effectiveness and implementation in the context of HIV care. Balancing pragmatism with rigor through the use of rapid analysis procedures and multiple methods increased the feasibility of the adaptation process.

Abstract

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.
