  1. a The variables of the number of incarceration (OR:1.39, CI95%: 1.20–1.62) and the prison term (OR:1.94, CI95%: 1.48–2.55) had a correlation with each other. The variable of the prison term was entered into multivariate logistic regression model because of its higher significant OR
  2. b Sexually transmitted diseases
