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.
