Purpose: Preconception health during adolescence determines future maternal and neonatal outcomes. In many low- and middle-income countries, adolescent girls face high rates of anemia, undernutrition, early marriage, and limited access to reproductive health information. In rural Bangladesh, inadequate awareness and poor health behaviors among adolescent girls contribute to long-term reproductive risks. Community health programs mainly focus on pregnant women and young children, overlooking adolescents and limiting early behavioral change opportunities. Mobile health education offers a scalable strategy to deliver timely, culturally appropriate information and promote improvements in preconception knowledge, attitudes, and practices (KAP). However, evidence targeting rural school-going adolescents remains limited.
Objective: To evaluate the effectiveness of mobile phone-based education in improving preconception knowledge, attitudes, and practices among adolescent girls in rural Bangladesh.
Methods: A school-based quasi-experimental study will be conducted from April 2026 to March 2027 in Kalapara Upazila, Bangladesh. A total of 190 adolescent girls aged 14-19 years will be recruited from two secondary schools, with one assigned as experiment and the other as control group. This design ensures equitable educational access while minimizing information contamination. Community health workers will implement a six-month mobile health education with weekly phone calls, SMS messages, and group counseling sessions. Educational modules will cover preconception KAP, including balanced nutrition, iron and folic acid intake, menstrual hygiene, reproductive awareness, prevention of early marriage, and healthy lifestyle behaviors. Outcomes will be assessed at baseline and endline using validated questionnaires. The control group will receive routine school health information. Ethical approvals will be obtained from institutions in Bangladesh and Japan.
Expected Outcomes: The intervention is expected to enhance preconception knowledge, foster positive attitudes, and promote healthy practices among adolescent girls, providing evidence for a scalable digital education model to strengthen adolescent reproductive health in resource-limited settings.
