Have We Substantially Underestimated the Impact of Improved Sanitation Coverage on Child Health? A Generalized Additive Model Panel Analysis of Global Data on Child Mortality and Malnutrition. PLoS One, October 2016. | Summary in Science Daily | Improving sanitation coverage may be one of the more effective means to reduce childhood mortality, but only if high levels of community coverage are achieved. Studies of the impact of sanitation that focus on the individual’s use of improved sanitation as the predictor variable rather than community coverage is likely to severely underestimate the impact of sanitation.

Risk Factors for Childhood Stunting in 137 Developing Countries: A Comparative Risk Assessment Analysis at Global, Regional, and Country Levels. PLoS Medicine, November 2016.
Efforts to further reduce stunting should be focused on fetal growth restriction and poor sanitation, and this will require refocusing prevention programs on interventions that reach mothers and families and improve their living environment and nutrition.

Costs of Diarrhoea and Acute Respiratory Infection Attributable to Not Handwashing: The Cases of India and China. Tropical Medicine and International Health, November 2016. Results from this study suggest large economic gains relating to decreases in diarrhea and acute respiratory infection for both India and China from behavior change programs to increase handwashing with soap in households.

Early Childhood Diarrhea Predicts Cognitive Delays in Later Childhood Independently of Malnutrition. American Journal of Tropical Medicine and Hygiene, September 2016. This study assesses the independent contributions of early childhood diarrhea (ECD) and malnutrition on cognitive impairment in later childhood. It provides evidence that ECD and stunting may have independent effects on children’s intellectual function well into later childhood.
