摘要:Adolescence is generally agreed to be the period between the ages of ten and nineteen Adolescents are atrisk of unintended pregnancies, sexually transmitted infections including HIV/AIDS, poor pregnancyoutcomes with consequent disrupted education and career goals. This descriptive cross-sectional studyexamined institutional behaviours as factors influencing the methodological approaches to sexualityeducation in semi-urban secondary schools in the study location. All the teachers in the five schools in thelocality were recruited for the study. A pretested interviewer administered questionnaire was employed toelicit information in each school. Data were analysed using independent t- test. The mean age of therespondents was 33.94 and 154 (71.3%) of them agreed that there was no deliberate official plans forsexuality education in secondary schools. Sixty-one percent of the participants also agreed that there wasno time to handle academics and sexuality issues at the same time, due to the workload, while154(71.3%) disagreed that the counselling unit was adequately staffed. A significant difference existedbetween Christian and Muslim schools in the pattern of methodological approaches to sexualityeducation. There was also a significant difference between private and public schools in the pattern ofmethodological approaches to sexuality education. It was therefore recommended that teachers shouldundergo sex education training, and necessary methodological approaches should be implemented ineach school to improve adolescents’ sexuality knowledge.
