In India, nearly 40 percent of all children are stunted — of extremely low height for their age — and nearly 30 percent are underweight. A new study from Harvard T.H. Chan School of Public Health has now pinpointed the five top risk factors responsible for more than two-thirds of the problem.
The study — the first to comprehensively analyze and estimate the relative importance of known risk factors for child undernutrition — appears online in Social Science & Medicine.
Examining an array of 15 well-known risk factors for chronic undernutrition among children in India, the study found that the five top risk factors were essentially markers of poor socioeconomic conditions as well as poor and insecure nutritional environments in children’s households.
Specifically, using data on nearly 29,000 children aged 6–59 months from the third India National Family Health Survey, conducted in 2005-06 (the latest data that is publicly available), the researchers found that the five most important predictors of childhood stunting and underweight were:
Meanwhile, factors such as Vitamin A, breastfeeding, use of iodized salt, improved water and sanitation, and even immunization — all currently high priority interventions in the global discourse on addressing undernutrition — accounted for less than 15 percent of the cases of undernutrition.
