What this trial studies

This is a hybrid effectiveness-implementation study conducted as a cluster randomized trial in two Cambodian provinces. Health centers are randomized to either receive a six-month nutrition intervention delivered by Village Health Support Groups with supervision from health center staff, or to continue usual services. Participants are adults 20 years or older who are underweight or overweight/obese, assessed at baseline, 3 months, and 7 months. The study will measure dietary diversity and use mixed methods to evaluate acceptability, adoption, feasibility, fidelity, and cost of delivering the intervention.
