Summary of Project: 
The National HIV Behavioral Surveillance System is a multisite project funded by the Centers for Disease Control and Prevention (CDC).  NHBS was established to identify behaviors that place individuals at-risk for contracting HIV/AIDS. NHBS operates through activities designed to monitor HIV risk behaviors in order to assist in prevention education, service initiatives, and allocation of prevention resources. Nationally, data is collected in 21 metropolitan areas2 that have the highest prevalence of HIV/AIDS cases. The project occurs in multiple cycles with each year targeting one of three high-risk populations including: a) men who have sex with men (NHBS-MSM); b) intravenous drug users (NHBS-IDU); and c) heterosexuals at risk for contracting HIV (NHBS-HET).

NHBS activities include:  a) core questionnaire that addresses the following areas: demographics, sexual history, alcohol and drug use history, HIV testing history, incarceration history, and prevention activities; b) local questionnaire that was developed based on input from service providers, community leaders, and individuals living in the metro Detroit areas; and c) HIV testing. All activities are anonymous.  NHBS recruitment methodologies vary according to cycles. Respondent Driven Sampling (RDS) was implemented for IDU1 and HET1 cycles and Venue Based Sampling was used for MSM1 cycle. 

Inception of Behavioral Surveillance in Michigan: 
Michigan has participated in numerous HIV surveillance activities and interview studies since 1986.  Prior to National HIV Behavioral Surveillance (NHBS), Michigan participated in the HIV Testing Survey (HITS) where we interviewed STD clients, injecting drug users (IDU) via street intercepts and men who have sex with men (MSM) in gay bars. After HITS, Detroit was one of three sites selected to do a pilot for the IDU cycle of NHBS.  We successfully tested 2 recruitment methodologies: Respondent Driven Sampling (RDS) and Targeted Driven Sampling (TDS).  Our shared experience was instrumental in choosing the sampling method that would be used for all sites during data collection for the IDU1 cycle.   In 2005, we received funding to participate in NHBS. Under the name of Project ASK, we successfully interviewed and collected data from 512 IDU's for the first cycle of NHBS. In 2005, we also participated in the High Risk Area (HRA) pre-pilot for the HET cycle to explore strategies for identifying HRAs. The pre-pilot involved mapping a variety of data using GIS software, and the results were presented at the CDC's National Principal Investigator meeting in October 2005. Michigan has been instrumental in providing service/ support for data collection methodologies in relation to NHBS. We have received funding for NHBS since 2005 and have completed data collection for NHBS- IDU1 (2005), HET1(2007), and MSM2 (2008)cycles.

2009 Data collection activities:
