The Behavioral Risk Factor Surveillance System (BRFSS) is a state-based system of health surveys that collects information on health risk behaviors, preventive health practices, and health care access primarily related to chronic disease and injury. For many states, the BRFSS is the only available source of timely, accurate data on health-related behaviors. BRFSS was established in 1984 by the Centers for Disease Control and Prevention (CDC); currently data are collected monthly in all 50 states, the District of Columbia, Puerto Rico, the United States Virgin Islands, and Guam. More than 350,000 adults are interviewed each year, making the BRFSS the largest telephone health survey in the world. States use BRFSS data to identify emerging health problems, establish and track health objectives, and develop and evaluate public health policies and programs. The BRFSS is a cross-sectional telephone survey conducted by state health departments with technical and methodologic assistance provided by CDC. States conduct monthly telephone surveillance using a standardized questionnaire to determine the distribution of risk behaviors and health practices among adults. Responses are forwarded to CDC, where the monthly data are aggregated for each state, returned with standard tabulations, and published at the year's end by each state. The BRFSS questionnaire was developed jointly by CDC's Behavioral Surveillance Branch (BSB) and the states. When combined with mortality and morbidity statistics, these data enable public health officials to establish policies and priorities and to initiate and assess health promotion strategies.

Hawaii Aging with HIV Cardiovascular Study (HAHCS) enrolled HIV-infected volunteer adults age 40 and over, recruited from the state of Hawaii. A natural history longitudinal study, HAHCS followed a cohort of 150 HIV positive subjects for five years. The study is based on observations that, while HIV-infected individuals now live longer because of the availability of highly active antiretroviral therapy, these individuals may be at increased risk of cardiovascular (CV) morbidity and mortality. Rates of well-accepted traditional CV risk factors such as diabetes/hyperglycemia, body morphology changes and smoking are high in the HIV population. Furthermore, there is growing concern that HIV per se may also contribute to CV risk.

HAHCS evaluated the cross-sectional and longitudinal impact of oxidative stress and inflammation on the development of subclinical atherosclerosis. Researchers assessed subclinical atherosclerosis functionally by brachial artery flow mediated vasodilatation (FMD) and structurally by intima-media thickness (IMT) as well as coronary artery calcium score obtained by dual source CT. Data include behavioral health indicators, medical history information, and medical test results. Demographic data include age, sex, and race.

Proyecto PACTo: Enhanced HIV Care Access and Retention for Drug Users in San Juan, Puerto Rico, 2013-2014 (ICPSR 39791)

Released/updated on: 2026-04-22

Geographic coverage: Puerto Rico

Time period: 2013-01-01--2017-01-01

This study evaluates the effectiveness of the Enhanced HIV Care Access and Retention Intervention in achieving HIV virologic suppression among HIV-infected substance users in San Juan, Puerto Rico. The implementation process and cost of the enhanced care approach, including implications for cost effectiveness, feasibility of expansion, and sustainability are also included in the evaluation process. This study consists of two multi-component phases: a pre-trial phase and a trial phase. The pre-trial phase consists of ethnographic and pre-implementation interviews, HIV provider surveys and a survey of employees within a community-based agency that is an integral part of trial implementation. Ethnographic and pre-implementation qualitative interviews were conducted prior to implementation of the trial to inform the development of assessment tools and the intervention, and to inform the selection of the appropriate neighborhoods/areas from which to recruit HIV-infected substance users. Employees of Iniciativa Comunitaria de Investigacion, Inc. (ICI), an existing community-based, non-profit organization that is responsible for conducting HIV testing, recruitment and outreach for the study, were invited to complete a survey to assess organizational readiness for change at ICI. HIV providers in major cities in Puerto Rico will be invited to complete a survey to assess their treatment practices and other issues pertaining to HIV care. The trial phase consists of an Assessment Cohort, a multicomponent Enhanced HIV Care Access and Retention Intervention, and an HIV Care Cohort.

Randomized Placebo-Controlled Trial to Assess the Impact of Oral Naltrexone on HIV Treatment Outcomes Among HIV-1 Infected Men Who Have Sex with Men and Transgender Women with Alcohol Use Disorders in Lima, Peru, 2014-2015 (ICPSR 39780)

Released/updated on: 2026-04-23

Geographic coverage: Lima, Peru

Time period: 2014-04-01--2015-12-01

The Seek, Test, Treat and Retain (STTR) Collaboration Project involved over twenty studies in the fields of HIV and drug abuse. These studies were independently developed, but were chosen for the collaboration because they focused on one or more steps of the HIV treatment cascade: Seek, Test, Treat and Retain. These studies were grouped into Criminal Justice-related studies and Vulnerable Population-related studies. The data collected by these studies included twelve common domains (e.g. demographic characteristics, mental health) in each of which a shared questionnaire or instrument was taken up by the studies and adapted to fit the study. This repository contains the collected data and documentation from the STTR collaboration.

This study in particular, assesses outcomes of Oral Naltrexone on HIV Treatment among HIV-1 infected men in Lima, Peru. A randomized blinded placebo-controlled clinical trial was conducted to determine if oral naltrexone (NTX) would improve the likelihood that HIV-infected participants with alcohol use disorders (AUDs) remain engaged in care and become highly adherent to antiretroviral therapy (ART), with acceptable safety.
