Crack-cocaine use and health status as defined by the SF-36.

The Medical Outcomes Study Short Form 36 (SF-36) was administered to 443 not-in-treatment, crack-cocaine smokers to explore the relationship between frequency of crack, alcohol, and tobacco use, addiction to these drugs, and health status. The reliability of the SF-36 with crack smokers was also assessed. Statistically significant, negative associations emerged between frequency of crack use and all SF-36 subscales except physical functioning. There were not significant associations between frequency of alcohol or tobacco use and any SF-36 subscale. Self-assessed addiction to crack was strongly and negatively associated with all SF-36 subscales: alcohol and tobacco addiction were also negatively associated with health status, but not to the degree of crack. The SF-36 produces reliable data on the health status of crack users and, as such, may have a useful role in assessments involving crack-using populations.

Injection drug users in the Midwest: an epidemiologic comparison of drug use patterns in four Ohio cities.

Variations in the drug use patterns of injection drug users (IDUs) can have important implications for public health efforts aimed at reducing drug abuse and the transmission of the human immunodeficiency virus. This article describes and compares the characteristics of IDUs living in four Ohio cities and compares African-American and White IDUs at a statewide level. Data from 2,001 IDUs who were recruited for the National AIDS Demonstration Research project between 1989 and 1991 in Columbus, Cleveland, Cincinnati, and Dayton were compared on a number of variables by city and by ethnicity using descriptive statistics and ANCOVA analysis. Significant differences among IDUs in the four cities exist for the use of alcohol, marijuana, cocaine, crack, heroin, speedball, other opioids, shooting gallery use, "safer" needle practices, treatment history, and self-help participation. Differences by ethnicity emerged on all variables except marijuana use, overall injection frequency, and incarceration experience. The results suggest that dramatic differences exist between African-American and White IDUs, and among IDUs in cities relatively close together, regardless of ethnicity. These findings should be considered when developing policy and programs for prevention and treatment activities targeting IDUs.

HIV needle risk behaviors and drug use: a comparison of crack-smoking and nonsmoking injection drug users in Ohio.

This study compares the drug use and needle risk behaviors among 733 crack-smoking injection drug users (IDUs) and 518 nonsmoking IDUs. Participants were recruited in Dayton and Columbus, Ohio, for the Cooperative Agreement for AIDS Community-Based Outreach/Intervention Research Program from 1992 to 1996. Crack-smoking IDUs were more likely to be male, African-American, and 30 to 40 years of age, but less likely to be married or living with a sex partner compared to nonsmokers. Daily crack users were less likely to be daily injectors but more likely to use alcohol daily when compared to non-crack users and less-than-daily crack smokers. IDUs who smoked crack less than daily were more likely to have injected with needles and syringes used by others. There is an urgent need for additional research on the relationship between drug injection and crack smoking as well as improved HIV risk-reduction interventions that include drug abuse treatment components focusing on issues surrounding crack-cocaine addiction.

History of sexually transmitted diseases infection, drug-sex behaviors, and the use of condoms among midwestern users of injection drugs and crack cocaine.

BACKGROUND AND OBJECTIVES: This study describes self-reported histories of sexually transmitted diseases (STD) with respect to gender and ethnicity and examines the factors that influence the use of condoms among heterosexual users of injection drugs and/or crack cocaine. STUDY DESIGN: A cross-sectional design was used to interview 1046 active users of illicit drugs living in Columbus and Dayton, Ohio. RESULTS: STD was common among 29% of the white men, 53.6% of the black men, 55.9% of the white women, and 64.7% of the black women self-reporting previous infection. Among women, stepwise logistic regression showed that cohabitating with a spouse or a sex partner (OR 0.28; 95% CI, 0.06 to 0.77) and exchanging sex for drugs (OR 0.31; 95% CI, 0.11 to 0.88) were associated negatively with always using a condom during vaginal sex in the previous month, whereas exchanging sex for money (OR 4.48; 95% CI, 1.88 to 10.95) was associated positively. Among men, cohabitating with a spouse or a sex partner (OR 0.13; 95% CI, 0.06 to 0.31), having had an STD (OR 0.53; 95% CI, 0.33 to 0.85), and currently using injection drugs (OR 0.52; 95% CI, 0.33 to 0.84) were associated negatively with condom use. CONCLUSIONS: Users of illicit drugs are at high risk for the acquisition and transmission of STD. More research is needed to understand better the sex practices of users of injection drugs and crack cocaine so that appropriate interventions can be developed.

Differences in drug use among rural and suburban high school students in Ohio.

This exploratory study examines differences in the prevalence of drug use by gender among twelfth grade students (n = 464) in selected rural and suburban high schools in west-central Ohio. The lifetime use of alcohol and other drugs is common among all groups. Proportionally fewer boys in rural schools than boys in suburban schools reported the use of marijuana, inhalants, and LSD, or recent episodes of drunkenness. No statistically significant differences emerged between girls in rural and suburban schools. Afterschool employment practices may help explain the observed differences.
