title: [Factors associated with the failure to use condoms among a population of parenteral drug addicts].
abstract: Use of condom in sexual intercourse by intravenous drug users has been assessed among a clinical population (n = 139). The multiple logistic regression results show that being a female (OR = 5.1, 95% CI = 2.0-13.2), on drug dependence for a 5-year period or more (OR = 3.0; 95% CI = 1.3-6.9) correlates with non-condom use. Less than 25% of females use condom in their sexual contacts. On the contrary a higher educational level seems to protect subjects against non-condom use (R = 0.3; 95% CI = 0.1-0.8). The most parsimonious model fitting to data at hand includes such variables as sex, educational level, partnership and frequency of sexual intercourse, as well as years on addiction. Other set of variables such as living and working status, age, and previous sexually-transmitted diseases experience are not required for the final model. Emphasis is placed on the need for developing programs aimed at modifying the high risk behavior intravenous drug users resort to in their sexual intercourse, stressing that the main dissemination cause of the human immunodeficiency virus among such a population is due to their sharing drug injections equipment.
