Alive & Thrive Lagos Implementation Research Study- Cohort Survey Datasets

This was a longitudinal cohort study designed to evaluate and measure the implementation processes of a breastfeeding counseling and support intervention offered to pregnant and postpartum women in private health facilities in Lagos State, Nigeria. The study took place in 20 private health facilities. Ten facilities were assigned to intervention and 10 to comparison based on their location within the existing intervention and comparison local government areas (LGAs) for our overall impact evaluation of the Alive & Thrive program in Nigeria. To be included in the study, facilities had to provide maternity and pediatric services, such as antenatal care, postnatal care, and immunizations, and be registered with the Association of General and Private Medical Practitioners of Nigeria and the Health Facility Monitoring and Accreditation Agency. To ensure that the investigators would achieve their sample size, selected facilities had a monthly average of ≥40 antenatal clients and ≥20 deliveries over 3 months. All eligible women attending antenatal care on the days of data collection were invited to participate until the target enrollment at each facility was achieved. The investigators collected survey data from a cohort of 1,200 women (600 per study arm) during the third trimester of pregnancy and when their child was 6 weeks and 24 weeks. The purpose of the surveys were to obtain data on the women's breastfeeding intentions (third trimester) and practices (6 weeks and 24 weeks), their breastfeeding knowledge and attitudes, and their exposure to the intervention. Stata MP, Version 16 Sample and sampling procedures: The selected facilities provided the current number of pregnant women in their third trimester. In the three lowest volume facilities (i.e., those with <35 clients in the third trimester) in each study arm, we attempted to enroll them all. For all other facilities, the number of women sampled was proportional to the facility size within each study arm. All eligible women attending antenatal care on the days of data collection were invited to participate until the target enrollment at each facility was achieved. Women who were attending antenatal care at the study facilities were approached by interviewers in the waiting room and invited to a private area for recruitment into the study. Women were eligible to enroll if they were ≥18 years old, in their third trimester of pregnancy, and were current clients of a private health facility selected for the study. At 6 and 24 weeks postpartum, the women continued to be eligible if their infant was alive and neither the mother nor infant had a health condition that caused breastfeeding to be contraindicated. Women remained in the study regardless of where they sought postnatal care and/or well child services. // Weighting: No sampling weights.
