Severe wasting among Indian infants

Abstract

Burden and risk factors for wasting in the first 6months of life among Indian children are not well documented. We used data from India's National Family Health Survey 4 to estimate the prevalence of severewasting (weight for length<-3 SD) among 18,898 infants under 6months of age. We also examined the association of severe wasting with household, maternal, and child-related factors using multivariable logistic regression analysis. Prevalence of severe wasting among infants less than 6months of age was 14.8%, ranging from 3.5 to 21% across states. Low birth weight (<2,500g; adjusted odds ratio [AOR] 1.40, 95% CI [1.19, 1.65]), nonutilization of supplementary nutrition by mother during lactation (AOR 1.23, 95% CI [1.05, 1.43]), and anthropometric assessment during summer (AOR 1.37, 95% CI [1.13, 1.65]) and monsoon months (AOR 1.53, 95% CI [1.20, 1.95]) were associated with higher odds of severe wasting. Infants aged 2 to 3months (AOR 0.78, 95% CI [0.66, 0.93]) and 4 to 5months (AOR 0.65, 95% CI [0.55, 0.73]) had lower odds of severe wasting as compared with the 0- to 1-month category. This analysis reveals a high burden of severe wasting in infants less than 6months in India. Preventive interventions must be targeted at reducing low birth weight due to fatal growth restriction and prematurity. Appropriate care practices at facilities and postdischarge with extra attention to those born small and sick can prevent further deterioration in nutritional status.
