Chicago African-American Network Health Study

The Chicago African-American Network Health Study (CAANHS) also known as uConnect is a NIDA funded study of the effect of social network dynamics on HIV risk of young (16-29 year old) Black men who have sex with men (YBMSM) from the Southside of Chicago, carried out in partnership with researchers at the University of Chicago.  YBMSM have the highest rate of new HIV infection of any single demographic group in the U.S. in spite of similar or even lower levels of individual risk than White MSM.  CAANHS used Respondent Driven Sampling (RDS), a network based rigorous chain referral sampling methodology for sampling hard to reach populations, to recruit the largest single site sample of YBMSM to date.

Over 600 YBMSM were recruited at baseline and over 80% of the baseline sample completed interviews in each subsequent round.  The interview collected information on both personal (confidant) and sexual networks as well as Facebook friends (using a custom designed application) along with bio-measures including HIV and syphilis.  It also collected extensive information on social support and influence, family relationships, social context, and HIV risk/reduction practices.  The ultimate goal is to better understand the social drivers that account for the high rates of HIV in this population and develop social network based interventions to reduce the transmission of HIV.
