Objective: The aim of this study was to identify associations between linear growth and relapse to acute malnutrition in children during the year following recovery from moderate acute malnutrition (MAM) in a longitudinal study. Nutrition programs frequently approach wasting and stunting as two separate conditions with distinct causes and effects; yet cross-sectional studies have identified an association between the two conditions. Longitudinal studies are useful to quantify the risk of relapse to acute malnutrition based on the trajectory of linear growth.
Methods: This was a secondary data analysis from a cluster randomized trial involving 1487 Malawian children 6-62 months old treated for MAM and enrolled upon recovery. Children were followed for one year, during which data were collected on anthropometric progress, symptoms of illness, and household food security. Multivariate fixed-effects logistic regression was used to identify associations between linear growth and relapse to acute malnutrition.
Results: Children who have recovered from MAM proved to be a high-risk population, with nearly half experiencing a decrease in height-for-age z-score (HAZ) for 12 months. Children whose HAZ was declining were more likely to relapse to MAM or SAM than those whose linear growth rate maintained or increased their HAZ (P
Conclusions: Our results add to the body of evidence suggesting that acute wasting is a harbinger of subsequent stunting. Children who experience poor linear growth following MAM are more likely to experience relapse. Given this bidirectional relationship between wasting and stunting, supplementary feeding programs should consider both when designing protocols, aiming to both optimize linear growth and achieve acute weight gain, as means to reduce relapse.
