  1. Legend: Each unit increase in age, district of residence, marital status, residing in a female headed household, condom use, genital ulcers and active syphilis were identified as the main socio-behavioural, sexual histories and STI related factors for HIV infection in this study population
  2. *Adjusted for age, sex, district of residence, religion and marital status
  3. *Note: Sex was forced to remain in the final model
