Brief summary
Globally, populations are experiencing increases in the double burden of malnutrition, commonly defined as maternal overweight/obesity and child stunting in the same household. This study will evaluate an integrated intervention combining food supplementation for pregnant and postpartum women and their infants with behavioral counseling to promote healthy maternal weight, nutrition, physical activity, and infant feeding practices. The goal is to reduce the double burden of malnutrition in rural Indigenous communities in Guatemala.
Detailed description
K'ASLEM (meaning "life" in the Kaqchikel Mayan language) is an individually randomized, parallel-group Hybrid Type 1 effectiveness-implementation clinical trial conducted in Indigenous Maya communities in Guatemala that have among the world's highest levels of double burden of malnutrition. 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.
Interventions
Monthly household food rations containing 5 food groups (eggs, fortified blended flour, oil, legumes, and fresh fruits and vegetables), providing approximately 150 kcal per capita per day assuming a median household of 5.
Individually tailored monthly home visits by trained educators addressing healthy gestational weight gain, postpartum weight management, maternal nutrition, physical activity, and infant feeding practices.
Usual care: Free pregnancy, postnatal, and infant care through the Ministry of Health services, including vitamin supplementation, infant vaccinations, and growth monitoring. Enhancements: Care navigation for high-risk or emergency conditions and ensuring infants aged 6 to 12 months receive government-recommended fortified blended flour.
