Effects of health education intervention on menstrual hygiene knowledge and practices among the adolescent girls of Pokhara Metropolitan, Nepal

Background Poor menstrual hygiene practices are one of the major public health problems in Nepal. Due to persistent taboos and socio-cultural constraints, adolescent girls are often unaware of scientific facts, knowledge, and practices related to menstrual hygiene. This paper aims to assess the effects of health education intervention on menstrual hygiene knowledge and practices among adolescent girls in Pokhara Metropolitan, Nepal.Materials and methods A true experimental study was conducted in two government basic schools in Pokhara Metropolitan, Nepal. The study population was adolescent girls who had attended the menarche. Firstly, a pretest with the help of a self-administered questionnaire was done to find out the socio-demographic information, knowledge and practices of menstrual hygiene. Next, health education sessions were conducted among the intervention group. Finally, after one month of intervention, a post-test was conducted among the intervention and non-intervention group. Data analysis was done through descriptive and inferential statistics.Results The findings showed significant improvement in the knowledge and practice level of adolescent girls on menstrual hygiene after health education intervention. Participants in the intervention group showed a significant increase in knowledge scores from 10.0% to 67.0%, while the non-intervention group remained unchanged at 7.5%. Good menstrual hygiene practices scores in the intervention group increased significantly from 22.5% to 67.0%, whereas the non-intervention group saw a slight rise from 20.0% to 22.5%. Regarding observed practice scores in menstrual hygiene, significant improvement was observed in the intervention group (45.0% to 100.0%) in contrast to the non-intervention group (25.0% to 27.5%).Conclusions This study highlights the crucial role of school health education interventions in promoting menstrual hygiene among adolescent girls. It emphasizes the importance of comprehensive educational programs tailored to early teenage girls, addressing timing, content, and delivery methods alongside ensuring the availability of Water, Sanitation and Hygiene (WASH) facilities.
