Exploring Behavioral Interventions to Improve Adherence to Multiple Micronutrient Supplements Among Pregnant Women in Cambodia

Plain-language summary

The goal of this mixed method study is to learn how three different behavioral interventions can help pregnant women in Cambodia take a daily multiple micronutrient supplement (MMS) as recommended during pregnancy and to understand how acceptable and useful these interventions are for them. The main questions it aims to answer are: * How do family support sessions, a tracking calendar, and short educational videos help pregnant women remember to take MMS every day and follow healthy pregnancy practices? * Which of these three interventions do pregnant women find most helpful and acceptable for supporting daily MMS use? Researchers will compare the three interventions (family support, tracking calendar, and educational videos) to see which approach best supports high MMS adherence and is most preferred by pregnant women. Participants will: * Take MMS tablets every day during pregnancy, starting from early pregnancy. * Invite two family members to attend a one-hour group session at the health center about MMS and healthy pregnancy, including how families can support daily supplement use. * Use a culturally tailored tracking calendar at home for three weeks to mark each day they take MMS and see reminders about clinic visits and healthy pregnancy behaviors. * Receive one short motivational video per week for three weeks via Telegram, featuring midwives who explain MMS, answer common concerns, and encourage daily supplement use. * Join focus group discussions after each intervention to share their experiences, preferences, and suggestions, and have remaining tablets counted to measure how many doses they took.
