title: A case-control analysis of risk factors in HIV transmission in South India.
abstract: A case-control study was done among patients attending our clinic for sexually transmitted diseases in South India to assess risk factors for human immunodeficiency virus (HIV) infection. Of 5,876 patients tested, 105 (1.79%) were HIV antibody positive (87 men, 18 women) by enzyme-linked immunosorbent assay and Western blot. They were compared with an equal number of age- and sex-matched patients without HIV antibody. Risk factors significant in the crude odds ratio analysis were occupation (truck drivers and truck cleaners), age at first exposure, and sexual contact with commercial sex workers. In the logistic regression analysis, only a history of past genital ulcer was a significant risk factor. Other important findings of this study were that (a) the spread of HIV to women is mostly from their infected husbands and (b) regular condom use was reported by less than 8% of patients and controls. Obviously, the current methods of education of the population are far from adequate.
