Mothers' Action Project for Child Health

MAP-CH is a cluster randomized clinical trial. A total of 66 proximally dwelling clusters of approximately 7 mothers will be randomized 1:1 to the intervention and control arms (33 clusters/arm). One child per family will be enrolled, resulting in a total sample size of 460. The target population of this study is low-income SA mothers of young children aged 12-66 months.

Recruitment: To identify eligible families for recruitment, the MAP-CH research staff will conduct a Mapping Project. Outreach workers will identify clusters of eligible families living close together in SA neighborhoods. Accompanied by local contacts project staff will visit homes of potential participants and assess eligibility and recruit eligible consenting mothers.

Intervention: Mothers assigned to the intervention group will participate in a 12-month, multi-session, group-based intervention. Intervention meetings will take place in participant homes and will be led in Bengali (or the language spoken by that cluster), by a skilled bilingual facilitator from our research staff. The intervention is designed to: 1) improve knowledge, attitudes, and behaviors related to reducing dietary sugar; and 2) increase maternal assertiveness and parenting skills related to healthy feeding; and 3) build lasting social networks supportive of these norms and behaviors among participants. Eighteen sessions will be delivered over 12 months.

Control group: Mothers assigned to the control arm will receive a series of packages and mailings.

Data collection: Interviews will be conducted in the home, by RAs at T1/Baseline, T2 (12months' post baseline) and T3 (18 months' post baseline). Data collected at each interview includes anthropometric data collection; and questionnaires/interviews. Social network data will also be collected at T1, 3M, 6M, T1, and T3. Dental caries assessments will occur at baseline and T3.

Analyses: The primary outcome is reduced d2-4mfs increment at 18 months' post baseline in the intervention compared to the control group. A secondary outcome is reduced weight gain velocity. Other outcomes include servings of sweetened foods and beverages, servings of junk food, use of bottles, maternal feeding behaviors, oral hygiene, and dental utilization. The investigators will also evaluate potential mediators and moderators of treatment impact including knowledge, assertiveness, depression, household empowerment, and social network quality.
