Résumé :

Background: Little is known about the long-term outcome of children treated for severe acute malnutrition (SAM) after nutritional rehabilitation. Objectives: To explore the association between SAM in childhood, noncommunicable diseases (NCDs), and low human capital in adulthood. Methods: We identified 524 adults (median age: 22 y) who were treated for SAM during childhood in Eastern Democratic Republic of Congo between 1988 and 2007. They were compared with 407 community unexposed age- and sex-matched subjects with no history of SAM. The variables of interest were cardiometabolic risk markers for NCDs and human capital. For the comparison, we used linear and logistic regressions to estimate the association between SAM in childhood and the risk of NCDs and ordinal logistic regression for the human capital. Results: Compared with unexposed subjects, the exposed participants had a higher waist circumference [1.2 (0.02, 2.3) cm; P = 0.015], and a larger waist-to-height ratio [0.01 (0.01, 0.02) cm; P < 0.001]. On the other hand, they had a smaller hip circumference [-1.5 (-2.6, -0.5) cm; P = 0.021]. Regarding cardiometabolic markers for NCDs, apart from a higher glycated hemoglobin (HbA1c) [0.4 (0.2, 0.6); P < 0.001], no difference was observed in other cardiometabolic markers for NCD between the 2 groups. Compared with unexposed participants, exposed participants had a higher risk of metabolic syndrome (crude OR: 2.35; 95% CI: 1.22, 4.54; P = 0.010) and visceral obesity [adjusted OR: 1.44 (1.09, 1.89); P = 0.001]. The prevalence of hypertension, diabetes, overweight, and dyslipidaemia was similar in both groups. Last, the proportion of malnutrition survivors with higher socioeconomic status level was lower. Conclusion: SAM during childhood was associated with a high risk of NCDs and lower human capital in adulthood. Thus, policymakers and funders seeking to fight the global spread of NCDs in adults in low-resource settings should consider the long-term benefit of reducing childhood SAM as a preventive measure to reduce the socioeconomic burden attributable to NCDs.
