Abstract
INTRODUCTION: Trichomoniasis is a relatively neglected area of research in Sri Lanka. Given the number of infections observed, an analysis of sociodemographic characteristics of patients would be valuable in prevention. MATERIALS AND METHODS: Data were collected from 359 newly registered women at a tertiary level sexually transmitted diseases clinic over a period of 18 months. Trichomoniasis was diagnosed by culture of vaginal swabs collected from the posterior fornix. RESULTS: The prevalence of trichomoniasis in the sample was 7.2%. Of those who tested positive for trichomoniasis, 76% were in the age group of 21-45 years, 68% were married and living with a spouse and 60% were unemployed. A diagnosis of Trichomoniasis was associated with being married (OR, 1.6; CI, 0.56-4.41), age over 33 years (OR=1.3, CI, 0.55-2.9), being employed (OR, 1.3; CI, 0.56 - 2.94), having an education of less than ten years at school (OR, 3.0; CI 1.28-7.26) and not using condoms during the last sexual act (OR 2.0, CI 0.84-4.86). The risk was less among commercial sex workers (OR, 0.3, CI: 0.14-0.85), those with multiple sexual partners (OR, 0.2; CI; 0.073-0.408) and women reporting extramarital sexual relationships (OR, 0.3; CI, 0.128-0.733). CONCLUSIONS: Education on safe sex and recognition of symptoms is currently targeted at high risk groups such as commercial sex workers. Extending these programmes to the rest of the community will further reduce the risk of transmission of trichomonas.
