What this trial studies

This is a randomized controlled experiment conducted at Family Health Centers in the Atakum district of Samsun between January 2024 and January 2025. Eligible postpartum women (baby aged 9–18 months) who are married, sexually active, have a regular menstrual cycle, a primary-school education, and do not use modern contraceptive methods will be randomized to receive sanitary pads with written and visual family planning messages or to a control group that receives no materials. The intervention aims to use packaging as a repeated, low-cost communication channel to influence knowledge and attitudes about family planning. Outcomes will compare changes in knowledge and attitude measures between the intervention and control groups using the planned sample size of roughly 39 participants per arm (with additional participants to increase power).
