Abstract
BACKGROUND: Short-term anthropometric outcomes are well documented for children treated for severe acute malnutrition (SAM). However, anthropometric recovery may not indicate restoration of healthy body composition. OBJECTIVE: This study aimed to evaluate long-term associations of SAM with growth and body composition of children 5 y after discharge from community-based management of acute malnutrition (CMAM). METHODS: We conducted a 5-y prospective cohort study, enrolling children aged 6 to 59 mo discharged from CMAM (post-SAM) (n = 203) and nonmalnourished matched controls (n = 202) from Jimma Zone, Ethiopia in 2013. Anthropometry and body composition (bioelectrical impedance) were assessed. Multiple linear regression models tested differences in height-for-age (HAZ), weight-for-age (WAZ), and body mass index-for-age (BAZ) z-scores; height-adjusted fat-free mass index (FFMI); and FM index (FMI) between groups. RESULTS: Post-SAM children had higher stunting prevalence than controls at discharge (82.2% compared with 36.0%; P < 0.001), 1 y (80.2% compared with 53.7%; P < 0.001), and 5 y postdischarge (74.2% compared with 40.8%; P < 0.001). Post-SAM children remained 5 cm shorter throughout follow-up, indicating no HAZ catch-up. No catch-up in WAZ or BAZ was observed. Post-SAM children had lower hip (-2.05 cm; 95% CI: -2.73, -1.36), waist (-0.92 cm; CI: -1.59, -0.23) and mid-upper arm (-0.64 cm; CI: -0.90, -0.42) circumferences and lower-limb length (-1.57 cm; 95% CI: -2.21, -0.94) at 5 y postdischarge. They had larger waist-hip (0.02 cm; 95% CI: 0.008, 0.033) and waist-height (0.013 cm; 95% CI: 0.004, 0.021) ratios, and persistent deficits in FFMI at discharge and 6 mo and 5 y postdischarge (P < 0.001 for all). No difference was detected in head circumference, sitting height, or FMI. CONCLUSIONS: Five y after SAM treatment, children maintained deficits in HAZ, WAZ, BAZ, and FFMI, with preservation of FMI, sitting height, and head circumference at the expense of lower-limb length, indicating a “thrifty growth” pattern. Research is urgently needed to identify effective clinical and public health interventions to mitigate these consequences of malnutrition.
