摘要: OBJECTIVES: To describe the epidemiology of Trichomonas vaginalis infection and its association with HIV infection, in women four African cities different levels infection. DESIGN: Cross-sectional study, using standardized methods, including a questionnaire laboratory tests, sub-Saharan Africa: two high prevalence (Kisumu, Kenya Ndola, Zambia), relatively low (Cotonou, Benin Yaounde, Cameroon). METHODS: In each city, random sample about 2000 adults aged 15-49 years was taken. Consenting men were interviewed their socio-demographic characteristics sexual behaviour, tested for HIV, syphilis, herpes simplex virus type 2 (HSV-2), gonorrhoea, chlamydial (women only) T. Risk factor analyses carried out trichomoniasis city separately. Multivariate analysis, however, only possible Kisumu Ndola. RESULTS: The significantly higher (29.3% 34.3% Ndola) than Cotonou (3.2%) Yaounde (17.6%). increased who reported more lifetime sex partners. an independent risk trichomonas [adjusted odds ratio (OR) = 1.8, 95% confidence interval (CI) 0.9-3.7] (adjusted OR 1.7, CI 1.1-2.7), but not A striking finding (40%) Ndola denied that they had ever sex. CONCLUSION: Trichomoniasis may have played role spread Africa be one factors explaining differences between regions Africa. remain unexplained, we lack data on men. More research is required interaction men, infections deny activity.
