The trial will enroll 766 pregnant women aged 16 years or older before 28 weeks gestation with 1:1 allocation to intervention and comparator arms. The intervention arm will receive two integrated interventions: (a) food supplementation for pregnant and postpartum women and for infants and (b) behavioral counseling to optimize maternal weight and promote healthy nutrition, physical activity, and infant feeding practices. The comparator is enhanced usual care, which includes routine government prenatal and postnatal services along with care navigation and provision of fortified flour for infants. Mother-child dyads will be followed until 12 months after birth. Co-primary outcomes are maternal weight and child length-for-age at 12 months after birth. Complementing these trial outcomes, the study will collect mixed-methods data on implementation outcomes and apply implementation mapping to develop strategies for future scale-up. The trial will also include an economic evaluation to inform policymakers of costs and cost-effectiveness. A major feature of the trial is a focus on pragmatism and fairness, working to enroll vulnerable families from rural Guatemala who stand most to benefit from the intervention but who are commonly excluded from clinical trials.",[42,50],{"label":43,"type":44,"description":45,"interventionNames":46},"Intervention Arm","EXPERIMENTAL","Participants will receive two integrated interventions from enrollment through 12 months postpartum.
