Risk factors for sexually transmitted diseases (STDs) were assessed among 54 male and 36 female patients attending a venereal disease clinic. Sociodemographic data and information on sexual behaviour/STD history were collected. Patients were examined and specimens taken for laboratory diagnosis. Multivariate logistic regression analysis revealed that the significant predictors of genital infections among the male patients were: being unmarried, having multiple sexual partners, exposure to a symptomatic sexual partner, high frequency of intercourse per week, having repeated episode(s) of STDs and practising coitus interfemoris. In the female patients, exposure to a symptomatic sexual partner and high frequency of intercourse per week were the only significant predictors.
