SNRG NHBS team concludes third year with 500 IDU interviews

On November 16, 2012, SNRG’s NYC National HIV Behavioral Surveillance (NHBS) IDU3 team concluded its third tri-annual round of interviews, and HIV and hepatitis B/C testing, with injection drug users (IDU) in New York City. More than 500 study participants were interviewed and tested at one of the three NYC NHBS field sites in Bushwick, Brooklyn; the Lower East Side, in Manhattan; and Mott Haven, in the Bronx.The NHBS study is a national CDC study conducted in cities with high rates of HIV prevalence that each year recruits a sample of a population at high risk for HIV (IDU, men who have sex with men, and heterosexuals at elevated risk for HIV). As in many SNRG studies, the study used respondent-driven sampling (RDS), a chain-referral strategy where study participants recruit future study participants. HIV and hepatitis B and C tests, and risk-reduction counseling were provided to all participants who agreed to testing. Participants were compensated for study participation and recruiting. Following the cyclical design of the NHBS, the SNRG NHBS team is now preparing for 2013 data collection with heterosexuals at elevated risk for HIV, in collaboration with the NYC Department of Health and Mental Hygiene, and the CDC.

SNRG’s NHBS NYC-team begins IDU Round (2012)

During 2012, the NYC National Behavioral Surveillance (NHBS) NYC team will recruit 500 New Yorkers who inject drugs, interview them about HIV risk and protective behaviors, and HIV testing history, and test them for HIV. As in past studies the team has conducted with NYC injection drug users (IDU), NHBS-IDU3 will use Respondent Driven Sampling to recruit the study sample, taking advantage of peer networks both to recruit study participants, and gain understanding of the network dynamics of HIV transmission in this high-risk population. The team recently received additional funds from the CDC to conduct Hepatitis B and C testing in conjunction with the main NYC NHBS-IDU3 study.

The team recently submitted a report to the CDC summarizing research about NYC IDU since the last such cycle in 2009. Of the 22 NYC IDU-related papers published from 2009-2011 identified through PubMed and Google Scholar searches, 5 were NHBS-based papers by the team, with another 6 by team members collaborating with others on other datasets.

The NYC NHBS team recently completed all data cleaning on the interview data from the 508 NYC MSM recruited during the 2011 recruiting cycle. Analysis and write-up will now get underway.

NHBS study surpasses 300 interviews

The National HIV Behavioral Surveillance study (NHBS) kicked off its venue based sampling of gay and non-gay identified men who have sex with men (MSM) in New York City on July 9, 2011. To date, roughly 304 men have agreed to participate in the study with roughly 290 eligible to participate; of those 290, roughly 275 also agreed to be tested for HIV. The team has sampled at bars, dance clubs, sex shops and stores, and parks, and in four of the five boroughs. To date, the most difficult populations to sample have been those men who identify as White, have higher than average incomes, and who frequent bars in midtown Manhattan. Conversely, the easiest populations to sample have been Black and Hispanic men with lower to no income and who frequent parks for sex. Participants who consent to HIV testing are given the option of receiving their results in 20 minutes via an oral swab called an Oraquick, or waiting two weeks for the results of an oral confirmatory test called an Orasure. Participants testing via Orasure can call on specified days to receive test results. To date, only three participants have tested positive via the Oraquick method; of those three, two departed before receiving their results because they decided they would rather not know their HIV status. Of those agreeing to be tested via Orasure, only five have called to receive their results, and all five were negative for HIV.

National HIV Behavioral Surveillance Study Among Men who Have Sex with Men

The New York City Department of Health and Mental Hygiene and its collaborators at John Jay College of Criminal Justice are conducting a large study of HIV risk among gay and non-gay identified men who have sex with men (MSM) in New York City. The study is part of a National HIV Behavioral Surveillance (NHBS) study funded by the Centers for Disease Control and Prevention (CDC), which is conducted in 20 cities in the United States with high rates of HIV.

The goals of the NHBS study are to understand the characteristics of MSM at risk of HIV infection in New York City and the factors associated with risk. This study will help plan for future health department efforts in preventing future HIV infections among MSM and address unmet needs in current HIV prevention activities.
