Comparative study of sexual health knowledge and practices among sexually active adolescent girls in co-educational and girls-only secondary school in Calabar, Nigeria

Introduction: there is little or no progress towards the attainment of sexual and reproductive health (SRH) targets of the Sustainable Development Goals (SDGs) in many developing country settings. Key SRH gap in these settings includes suboptimal knowledge-based safe sexual practices, especially among adolescent girls as a vulnerable subpopulation. Unique features of school environmental settings including gender segregation have not been harnessed for costeffective sexual health education, perhaps due to the current paucity of literature. This study was aimed at comparing sexual health knowledge and practices, between sexually active adolescent girls in co-educational and girl-only secondary schools in Calabar, Nigeria. Methods: cross-sectional comparative study design was used. Sexually active adolescent girls were randomly recruited from coeducational and girl-only secondary schools in Calabar, Nigeria. Validated questionnaire developed by the United Nations Educational Scientific and Cultural Organization (UNESCO), was used to assess sexual health knowledge and behavioral practice. Factors associated with a satisfactory level of knowledge were assessed using the Chi-square test. Data analysis was done using SPSS version 24.0, with the p-value set at 0.05. Ethical approval was obtained before data collection. Results: one hundred and twenty respondents were studied, comprising an equal proportion of sixty (60) in co-educational and girlonly schools. Mean age and age at sexual debut were 16.4 +/- 1.8 and 14.3 +/- 2.2 years, respectively. Compared with group 1 (co-education), respondents in group 2 (girl-only) had significantly higher mean knowledge scores (26.1 vs. 30.4, p<0.05). Fifty respondents (41.7%) had a satisfactory level of knowledge of sexual health. There was no significant difference in mean practice scores comparing groups 1 and 2 (20.4 vs. 21.5, p>0.05). Internet use, unmarried parental status, and not living with both parents, were associated with unsatisfactory levels of knowledge on sexual health. Conclusion: compared with co-educational schools, girl-only schools have better sexual health knowledge, but a similar level of behavioral practices. There is a need for improvement in sexual health education efforts among adolescent girls, perhaps with more focus on coed schools, within the context of potential inherent disadvantage in the school environmental setting.
