Effects of water quality, sanitation, handwashing, and nutritional interventions on diarrhoea and child growth in rural Bangladesh: a cluster randomised controlled trial

Diarrhoea and growth faltering in early childhood are associated with subsequent adverse outcomes. This trial aimed to assess whether water quality, sanitation, and handwashing interventions alone or combined with nutrition interventions reduced diarrhoea or growth faltering. Overall the trial found that nutrient counselling and supplementation modestly improved linear growth, but that there was no benefit to the integration of water, sanitation, and handwashing with nutrition.
