Multivariate analysis of risk factors associated with genital ulcer disease among incarcerated males in Sindh.

Objective: To evaluate the potential risk behaviors associated with the lifetime risk of self reported genital ulcer disease (GUD) among prison inmates.

Setting: Prison inmates from 14 prisons of Sindh Province.

Methods: A cross-sectional study was conducted on 3395 prison inmates during July to December, 1994. A questionnaire was used to assess the lifetime risk of self-reported GUD (whether or not the subject was ever affected with GUD up to present age) and to investigate demographic markers and risk behaviors for their possible association with lifetime risk of GUD using logistic regression analysis.

Results: The reported lifetime risk of GUD in the study sample was 11.4% (386/3395). In final multivariate logistic regression model the sexual behaviors which were independently associated with GUD were having sexual intercourse with female (adjusted OR = 1.7; 95% CI: 1.3-2.3, P = 0.0002), sexual intercourse with a prostitute (adjusted OR = 1.5; 95% CI: 1.2-2.0, P = 0.0008), sexual intercourse with man (adjusted OR = 2.2; 95% CI: 1.7-2.7, P = < 0.001) and sexual intercourse with man during current incarceration (adjusted OR = 1.9; 95% CI: 1.2-2.9, P = 0.0071).

Conclusion: Health education needs to re-enforce monogamous relationship for high risk groups such as in our study. Although infrequent condom use was not a risk factor for GUD in this study, yet based on the results of previous studies, promotion of condom use should be the component of health education program.
