Abstract
Background: Childhood malnutrition is common in Malawi, and the standard treatment, which follows international guidelines, results in poor recovery rates. Higher recovery rates have been seen in pilot studies of home-based therapy with ready-to-use therapeutic food (RUTF). Objective: The objective was to compare the recovery rates among children with moderate and severe wasting, kwashiorkor, or both receiving either home-based therapy with RUTF or standard inpatient therapy. Design: A controlled, comparative, clinical effectiveness trial was conducted in southern Malawi with 1178 malnourished children. Children were systematically allocated to either standard therapy (186 children) or home-based therapy with RUTF (992 children) according to a stepped wedge design to control for bias introduced by the season of the year. Recovery, defined as reaching a weight-for-height z score > −2, and relapse or death were the primary outcomes. The rate of weight gain and the prevalence of fever, cough, and diarrhea were the secondary outcomes. Results: Children who received home-based therapy with RUTF were more likely to achieve a weight-for-height z score > −2 than were those who received standard therapy (79% compared with 46%; P < 0.001) and were less likely to relapse or die (8.7% compared with 16.7%; P < 0.001). Children who received home-based therapy with RUTF had greater rates of weight gain (3.5 compared with 2.0 g · kg−1 · d−1; difference: 1.5; 95% CI: 1.0, 2.0 g · kg−1 · d−1) and a lower prevalence of fever, cough, and diarrhea than did children who received standard therapy. Conclusion: Home-based therapy with RUTF is associated with better outcomes for childhood malnutrition than is standard therapy.
