Evaluating Bundling of Nutrition-specific Interventions

Background: 1. Burden: The prevalence of stunting among the under-five children in Bangladesh was \>55% in 1997, which reduced to 41.9% in 2011. This reduction took 14 years to achieve with existing interventions, and till today Bangladesh remains among the countries with the highest stunting prevalence. 2. Knowledge gap: In the Lancet series on Maternal and Child Nutrition, Bhutta et al (2013) modelled the effect of 10 direct interventions on lives saved and economic costs in 34 countries which contains 90% of the children with stunted growth. Their findings suggested that at 90% coverage, these interventions could cut down under-5 year mortality by 15% and avert one-fifth of stunting. The total additional annual cost was estimated at $9.6 billion. There is a dearth of primary research, however, to determine a feasible, effective bundle of interventions for developing countries. 3. Relevance: This study will review and test different sets of nutrition-specific intervention bundles in a cohort of pregnant women and the subsequent impact on the length-for-age Z score (LAZ) of their offspring from that pregnancy. Hypothesis: Five selected nutrition-specific interventions implemented during early pregnancy and during first two years of child's life in different bundles will cause a shift of 0.4 in mean LAZ score among children at 24 months of age compared to those in comparison arm. Methods: The investigators propose a community-based randomized trial (cRCT) to evaluate the effectiveness of different combinations of the five selected nutrition-specific interventions and identify the best combination for improving childhood LAZ. Selected interventions include prenatal nutrient supplementation; intensive counselling on prenatal nutrition, exclusive breastfeeding and timely complementary feeding; and nutrient supplementation during 6-23 months of child's age.
