Risk Factors for AIDS Among Intravenous Drug Users Study, New York City, 1991-1995 (ICPSR 36215)

Principal Investigator(s): Des Jarlais, Don, Beth Israel Medical Center

Summary:

The Risk Factors for AIDS among Intravenous Drug Users study is an ongoing series of cross-sectional studies that recruits participants from a storefront research site and from one of New York City's largest detoxification facilities. The goal of the study was to assess the potential effectiveness of HIV interventions by examining participants' drug use, risk behavior, and AIDS prevention knowledge and activities.

The dataset combines survey responses taken from interviews conducted at the Bellevue Methadone Maintenance Treatment Program, the Beth Israel Medical Center and from a high drug use area in Lower East Side of Manhattan. All participants were at least 18 years of age or older. Participants from the Beth Israel Medical Center and the Lower East Side were given face-to-face interviews based on a World Health Organization Multi-Centre questionnaire. Data from the Bellevue Methadone Maintenance Treatment Program were extracted from patients' clinical files. Minimal demographic and HIV risk behavior were included in the methadone patient responses in these data to protect their anonymity. Blood samples were taken from participants to test for HIV.

These data also contain information on topics including participant demographics, alcohol use, drug use, substance abuse treatment, needle sharing habits, sexual behavior, social networks, HIV testing services, as well as mental and physical health. Drugs use explored in this study includes heroin, cocaine, crack, methadone, amphetamines, ice, tranquilizers, barbiturates and other drugs.

This dataset is public-use. A restricted-use version of the dataset is also available with the associated study number 35078. There are 2,907 respondents and 902 variables in the dataset.

Access Notes

  • The public-use data files in this collection are available for access by the general public. Access does not require affiliation with an ICPSR member institution.

Scope of Study

Subject Terms:    AIDS, cocaine, drug treatment, drug use, health behavior, health education, heroin, HIV, intravenous drug use, prostitution, sexual behavior, sexually transmitted disease, social behavior, social networks

Geographic Coverage:    New York City, United States

Time Period:   

  • 1991--1995

Date of Collection:   

  • 1991--1995

Universe:    Intravenous drug users age 18 years and older in New York City.

Data Type(s):    clinical data, survey data

Data Collection Notes:

This dataset contains waves 3 and 4 of the survey. However, question text is only available for wave 4. The wave 3 questionnaires were destroyed in an accident. The variable order follows the questionnaire for wave 4. ICPSR staff added wave 3 variables in a pattern that follows the wave 4 questionnaire.

The Principal Investigator computed variables to reflect the number of times the respondent did certain activities. These variables have the same variable names and labels as the originals except the letter "K" is added to the end of the variable names and "(Converted to number of times)" is added to the end of the variable labels.

The Principal Investigator computed variables to reflect the percentage of the time the respondent did certain activities. These variables have the same variable names and labels as the originals except the letter "F" is added to the end of the variable names and "(Converted to Percentage)" is added to the end of the variable labels.

At the end of the dataset there are 16 variables that are listed in the codebook under the bookmark "Test Results". These variables relate to HIV testing results.

In order to create a public use file ICPSR made changes to the original dataset to protect respondent confidentiality. ICPSR top and/or bottom coded variables, recoded variables into or combined categories, restricted the SEX variable values to male and female, and masked variables that posed a confidentiality risk. Please see the notes in the PDF codebook for further details.

Dr. Des Jarlais is willing to discuss potential analyses if needed. He can be reached at DDesjarlais@chpnet.org.

There is a restricted version of this study that contains fewer confidentiality protections performed by ICPSR compared with the public-use file provided here. Please visit ICPSR 35078 to view the codebook and apply for access to this restricted data.

Methodology

Sample:    The respondents were convenience sampled from the Bellevue Methadone Maintenance Treatment Program, the Beth Israel Medical Center and from a high drug use area in the Lower East of Manhattan.

Time Method:    Longitudinal: Trend / Repeated Cross-section

Weight:    There are no weight variables associated with this study.

Mode of Data Collection:    face-to-face interview, on-site questionnaire

Response Rates:    90 percent

Extent of Processing:   ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:

  • Standardized missing values.
  • Created online analysis version with question text.
  • Performed recodes and/or calculated derived variables.
  • Checked for undocumented or out-of-range codes.

Restrictions: Users are reminded that these data are to be used solely for statistical analysis and reporting of aggregated information and not for the investigation of specific individuals.
