Mortality among Hispanic drug users in Puerto Rico

This paper assesses mortality rate for a cohort of drug users in Puerto Rico compared with that of the Island's general population, examining causes of death and estimating relative risk of death. Date and cause of death were obtained from death certificates during 1998. Vital status was confirmed through contact with subjects, family, and friends. HIV/AIDS was the major cause of death (47.7%), followed by homicide (14.6%), and accidental poisoning (6.3%). Females had higher relative risk of death than males in all age categories. Not living with a sex partner and not receiving drug treatment were related to higher mortality due to HIV/AIDS. Drug injection was the only variable explaining relative risk of death due to overdose. Puerto Rico needs to continue developing programs to prevent HIV/AIDS among drug users. Special attention should be given to young women, who appear to be in greatest need of programs to prevent early mortality.

Crack use in Puerto Rico: evidence of a recent epidemic

This study examines the prevalence of crack use among out-of-treatment drug users in the San Juan metropolitan area. Of the sample of 849 drug users, 310 (36.5 percent) were crack users only, 179 (21.1 percent) were drug injectors and crack users, and 360 (42.4 percent) were drug injectors only. To study the characteristics of crack users we selected the subjects who reported the use of crack only. Of the 310 subjects, 193 (62.3 percent) men and 117 (37.7 percent) women, the mean age was 29 years. Significant differences were observed by gender. Females reported higher education, living in a nuclear family, crack/cocaine as the first drug used, history of sexually transmitted diseases and higher rates of HIV seropositivity. Males were more likely to report income from illegal activities, incarceration, use of multiple drugs, and more years of drug use. Among those sexually active, females were more likely to practice unprotected vaginal sex, have multiple sex partners, engage in prostitution (exchange of sex for money and/or drugs) and use condoms

Mycobacterium tuberculosis infection among crack and injection drug users in San Juan, Puerto Rico

This study aims to determine the prevalence of Mycobacterium tuberculosis infection and its association with HIV and other health risk factors among drug users. A sample of 716 IDUs and crack users were enrolled from community sites. Consenting subjects were tested for HIV serum antibody status. Drug users with an unknown PPD status were administered a PPD skin test and an anergy panel of three antigens (Candida, mumps and tetanus). Overall, 68 (10.3 percent) were reactive to the PPD skin test, 240 (34.7 percent) were HIV positive and 195 (29.5 percent) showed cutaneous anergy. Participants infected with tuberculosis (TB) were more likely to be HIV seropositive, and to have a history of incarceration and residential drug treatment than those not infected. In addition, TB infection was more prevalent among intravenous drug users (IDUs) and shooting gallery managers. These findings suggest that drug users should be considered at high risk for TB and HIV infection. Innovative programs to monitor both infections among drug users are needed to arrest what can become a dual epidemic of HIV and TB in the near future
