Event Description

Title talk: Multi-level Risk Factors for HIV Prevention and Care Among Black Sexual Minority Men: The N2 Cohort Study

Speaker: Dustin T. Duncan, ScD, Associate Professor, Co-Director of the Social and Spatial Epidemiology Unit and Director of the Columbia Spatial Epidemiology Lab at Columbia University's Mailman School of Public Health

This talk will describe the design, sampling methods, data collection, and main findings to-date of the ongoing 'Neighborhoods and Networks (N2) Cohort Study' including the recently launched follow-up study to the Neighborhoods and Networks (N2) study, which we refer to as N2 Part 2 (N2P2). N2 employs a prospective longitudinal design. The original sample includes Black sexual minority men (SMM) participants in Chicago recruited via respondent-driven sampling and assessed every six months over two years of follow-up. Participants enrolled in Jackson, New Orleans and Baton Rouge were originally recruited through existing health and community services and assessed every six months over one year of follow-up. Mobility within and between neighborhoods was assessed using global positioning system (GPS) technology, making the N2 study the largest GPS-based study of HIV disparities in any SMM population. Social and sexual networks among Black SMM were studied through egocentric network inventories as well as newer methods of creating meso-level networks that involve social media (Facebook) and mobile phone contacts.

We will also discuss how the N2P2 study will apply an observational-implementation hybrid design in order to help us achieve findings that support rapid translation, a critical priority among populations such as Black SMM that experience long-standing inequities, with regards to HIV and other health-related outcomes.
