RESUMO
BACKGROUND: Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. The disease affects all ages and both sexes but more prevalent among the sexually active age group of 15-49 years. The purpose of the current study was to determine the prevalence and factors associated with syphilis infection among outpatients 15-49 years in the Asikuma Odoben Brakwa District of Ghana where high levels of infection were earlier reported among antenatal women. METHODS: A descriptive cross-sectional study was carried out in 13 randomly selected health facilities. Blood samples were collected and tested for syphilis infection and a questionnaire administered to determine factors associated with the disease. RESULTS: A total 277 patients aged 15-49 years participated in the study. The overall prevalence of syphilis infection was 3.2% (9/277), with 5.7% (6/105) and 1.7% (3/172) among males and females respectively. Significant factors associated with syphilis infection included sub-district of residence, (χ2 (4) = 31.20, p < 0.001) and history of coerced sexual intercourse (χ2 (1) =7.49, p = 0.006). CONCLUSIONS: The prevalence of syphilis infection was high among male patients who lived in rural areas. Having a history of coerced sexual intercourse was a strong predictor for syphilis infection. Access to sexually transmitted infection control interventions in rural communities including health education may help control the disease.
