Objective: The high prevalence of sexually transmitted infections (STIs) including human immunodeficiency virus (HIV) among Nigerian young people has been linked to poor knowledge, attitudes and risk behaviour. This study evaluated the effectiveness of a sexuality education programme (SEP) in improving adolescents’ STI/HIV knowledge and attitudes and reducing risk behaviour. Design: A quasi-experimental pre–post study was conducted. The experimental group ( n = 189) and comparison group ( n = 195) comprised senior secondary school students. Data were collected via a validated self-report questionnaire. A paired t-test, an independent t-test and a one-way between-group analysis of covariance (ANCOVA) were used to analyse the data. Setting: Three hundred eighty-four young people aged 15–20 years at low and high risk for STI/HIV infection participated in the SEP in a school setting in Northeast Nigeria. Results: There were significant post-intervention improvements in students’ knowledge, attitudes and practices in the experimental group ( p < .001). A t-test showed that after the SEP, the mean scores of STI/HIV knowledge (11.25 ± 3.39 vs 8.23 ± 3.60) and attitudes (29.63 ± 6.21 vs 35.38 ± 7.86) were significantly higher in the experimental group than that in the control group. Similarly, the mean risk behaviour score (6.83 ± 2.10 vs 5.64 ± 2.27) was higher in the experimental group than that in the control group post-intervention. Conclusion: The school-based SEP increases STI/HIV knowledge, improves positive attitudes and reduces STI/HIV risk behaviour among school young people in Nigeria.

Background: Gestational diabetes mellitus (GDM) is a disease condition present during pregnancy and if not properly managed would have severe effect on the maternal and neonatal health. This research determined the effect of diabetes education program (DEP) on gestational diabetes mellitus knowledge (GDMK) among diabetic pregnant women (DPW) and significant differences within groups.Methods: This study was based on a pretest – posttest measures of experimental research design involving experimental (n=110) and control (n=110) groups. A total of 220 DPW were purposively recruited from public hospitals in Nigeria between October and December 2019. The DEP was delivered to DPW in experimental group. The Gestational Diabetes Mellitus Knowledge Questionnaire (GDMKQ) of 0.774 was used for data collection. The statistical analysis was completed using IBM SPSS version 22. Results: The results revealed that no statistically significant difference existed on GDM history (P=0.801>0.05), smoking habit (P=0.0615>0.05), parity status (P=0.503>0.05), and level of education (P=0.720>0.05), while difference was observed on alcohol status (P=0.011<0.05), and age by birth (P=0.009<0.05). Also, while no significant difference existed between the DPW in the treatment and control groups on GDMK pretest measures (P=0.901>0.05), difference existed between the DPW in the intervention and control groups on GDMK posttest scores (P=0.026<0.05). Also, the higher percentage score (78%) of DPW in the experimental group in the posttest GDMK measures which is higher than the score in the pretest measures (55%) of the same group were indications that DEP has significant effect on GDMK among DPW.Conclusion: This demonstrates that reliable interventions are effective in combating pregnancy-related complications. This requires collaborative efforts by concerned bodies to combat notable complications during pregnancy using reliable intervention.Trial Registration: In retrospect, the Pan African Clinical Trial Registry documented the study with registration trial code (Trial No.: PACTR201903003187005)
