Poor growth and severe childhood stunting is very common in rural Malawi and elsewhere in Sub-Sahara Africa. To date, few interventions have proven successful in promoting linear growth in early childhood. Our preliminary results from Malawi suggest that a year-long daily complementary feeding of infants with a high-energy, micronutrient-fortified spread (FS) may markedly reduce the incidence of severe stunting before the age of 18 months. In the present study the investigators will more carefully analyze the efficacy in linear growth promotion and other health benefits of this product when provided as a complementary food to infants between 6 and 18 months of age.
The study will be conducted in Lungwena area, Mangochi District, rural Malawi. Six-month old healthy infants are identified through community surveys in the study area. 840 infants meeting set criteria are randomized into receiving the following intervention between 6 and 18 months of age: 1) standard treatment ie no extra food supplements (but dietary supplementation between 18 and 30 months of age) (ST-DI, control group), 2), "standard" fortified spread with milk-powder as the protein source (FSm), 3) modified fortified spread with soy-powder as the protein source (FSs), or 4) fortified maize-soy flour (likuni phala, LP). The families receive the food supplements at 2-weekly intervals and the participants undergo an anthropometric and developmental evaluation and laboratory analyses at 12-week intervals. Outcome analyses are done at 18 and at 36 months of age.
The impact of the dietary interventions will be primarily assessed by comparing the incidence of severe stunting in the four study groups. Secondary outcomes include a number of anthropometric variables, morbidity, developmental milestones, and laboratory parameters. The study will also produce descriptive data on possible mechanisms for growth failure among the trial subjects.
