Abstract
This study examines the factors influencing sexual and reproductive health (SRH) knowledge among in-school adolescents in Nigeria. Data were collected from a sample of 1,133 adolescents through a semi-structured survey questionnaire. Descriptive statistics, and logistic regression analysis were employed to analyze the data. Adolescents' knowledge levels on critical aspects of SRH education reveal varying levels of comprehension across domains. While 35.7% of adolescents demonstrate understanding of the anatomy and physiology of the reproductive system, only 8.0% display comprehension of contraception and birth control methods. Logistic regression coefficients unveil significant predictors of SRH knowledge, with senior secondary students demonstrating higher odds of SRH knowledge compared to junior secondary students (OR = 2.482, 95% CI [1.335, 3.693]). Urban residence is associated with higher odds of SRH knowledge (OR = 1.172, 95% CI [0.084, 1.350]). Healthcare providers significantly influence adolescents' SRH knowledge (OR = 3.519, 95% CI [2.853, 4.271]), while comfortable discussing SRH topics with teachers predicts higher odds of SRH knowledge (OR = 3.101, 95% CI [2.245, 3.355]). These findings underscore the need for tailored and comprehensive SRH education programs to address knowledge gaps and empower adolescents with accurate information and skills necessary for making informed decisions regarding their sexual health.
