Methods	Cluster‐randomised trial recruiting women from 29 communes in Vietnam
Participants	Women recruited when registering for marriage
Interventions	Food supplement 5 days/week from marriage to term (˜18 months) Food supplement 5 days/week from 16 weeks' gestation to term (˜5 months) Routine prenatal care
Outcomes	The primary outcome is birthweight and the secondary outcome is the prevalence of prematurity. Other outcomes include maternal micronutrient status (iron, zinc, folic acid, vitamins A and B12), the incidence of infections; infant growth and infections from 0‐6 months of age are also assessed. Maternal data and information are measured at recruitment, 16, and 34 weeks' gestation. Infant anthropometric status is measured at birth, 1, 3, and 6 months. Infant gestational age is assessed at birth to determine the prevalence of pre‐term deliveries, and the mother’s activity or physical work during pregnancy is also determined.
