title: Determinants of sexual activities and contraceptive usage among adolescents in high schools in Ogbomoso, a semi-urban settlement in Nigeria.
abstract: BACKGROUND
  Abortion complications constitute 13% of maternal deaths worldwide and 40% of maternal deaths in Nigeria, while 80% of patients with abortion complications are adolescents.
  
  
  OBJECTIVE
  Assessing the adolescents' knowledge and attitude and the determinants of their sexual activities and contraceptive usage.
  
  
  METHODS
  This was a cross-sectional study conducted among high school students of Ogbomoso - a semi-urban settlement. Stratified multistage randomization was used to select one high school from each of five local government areas of the study site. Students were interviewed with pretested questionnaire to sought information on demographic status, family type, knowledge of sexuality, and contraceptive usages.
  
  
  RESULTS
  The age range of the respondents was 10-19 years with mean±SD age 13.7±1.9 years. Among them, 6.5% were sexually active. Of the respondents, 56.8% scored good knowledge about sexuality and contraception and 57.5% respondents had good attitude to contraception. Age (p=0.004) and father's education (p=0.001) were factors associated with knowledge about sexuality and contraception, while mothers' occupation (p=0.02) and fathers' occupation (p=0.001) and education (p=0.04) were significantly associated with positive attitude toward contraception.
  
  
  CONCLUSIONS
  This study revealed that a significant percentage of the studied adolescents had poor knowledge and attitude toward contraception, and many of the sexually active respondents had inaccurate knowledge on the use of contraceptives and where it could be obtained.
