Background: Intrauterine growth restriction may be reduced by supplementing maternal diets during pregnancy, but few studies have assessed the impact of combined prenatal and postnatal interventions on child growth. Objective: We tested a hypothesis that provision of small-quantity lipid-based nutrient supplements (SQ-LNSs) to mothers in pregnancy and 6 mo postpartum and to their infants from 6 to 18 mo of age would promote infant and child growth in the study area in rural Malawi. Methods: We enrolled 869 pregnant women in a randomized trial in Malawi. During pregnancy and 6 mo thereafter, the women received daily 1 capsule of iron-folic acid (IFA), 1 capsule containing 18 micronutrients (MMN), or one 20-g sachet of SQ-LNS [lipid-based nutrient supplements (LNS), containing 21 MMN, protein, carbohydrates, essential fatty acids, and 118 kcal]. Children in the IFA and MMN groups received no supplementation; children in the LNS group received SQ-LNSs from 6 to 18 mo. Primary outcome was child length at 18 mo. Results: At 18 mo, the mean length in the IFA, MMN, and LNS groups was 77.0, 76.9, and 76.8 cm (P = 0.90), respectively, and the prevalence of stunting was 32.7%, 35.6%, and 37.9% (P = 0.54), respectively. No intergroup differences were found in the mean weight, head circumference, or midupper arm circumference or the proportions with low z scores for these variables (P > 0.05). Covariate adjustment did not change the analysis results, and the associations between the intervention and child length were not modified by maternal parity, age, or nutritional status (P > 0.10). Conclusions: The findings do not support a hypothesis that provision of SQ-LNSs to women in pregnancy and postpartum and to children from 6 to 18 mo of age would promote child growth in this Malawian study area.
