Summary of "Water, Sanitation, Hygiene, and Nutrition in Bangladesh: Can Building Toilets Affect Children's Growth?"

Core Content

This World Bank study explores the relationship between water, sanitation, hygiene (WASH) and nutrition in Bangladesh, with a focus on how improving WASH infrastructure can influence child growth and undernutrition. It emphasizes that while WASH improvements are essential, they alone are not sufficient to significantly reduce undernutrition and must be integrated with other interventions.

Main Points

• Undernutrition in Bangladesh remains a significant public health issue, with high prevalence among children under five years of age. In 2013, 38.7% were stunted and 35% were underweight.
• The health sector has been the primary focus for addressing undernutrition, but its interventions have had limited impact on nutritional outcomes.
• WASH interventions are increasingly recognized as important for reducing undernutrition, but their effect is not as strong as previously thought.
• A new hypothesis by Humphrey (2009) suggests that the main pathway from poor sanitation to undernutrition is through tropical/environmental enteropathy, a subclinical condition that affects nutrient absorption and utilization in the small intestine.
• Diarrhea is both a cause and effect of undernutrition, but recent evidence indicates a weaker link between the two than previously assumed.
• Hygiene promotion is identified as the weakest link in the WASH sector, despite improvements in sanitation and water access.

Key Findings

• Water and sanitation improvements have been significant in Bangladesh, with a notable reduction in open defecation (from 42% in 2003 to 3% in 2012). However, the use of improved sanitation facilities remains low at 57%, and hygiene practices are still lacking.
• Hygiene practices, such as handwashing with soap, are underutilized. Only 40% of households have access to water and soap for handwashing, and 13% of children aged 3–5 years wash hands with soap during key moments.
• The government has developed several policies and strategies for WASH, but implementation remains a challenge due to lack of coordination, limited resources, and insufficient incentives for cross-sectoral collaboration.
• Multisectoral approaches are essential for tackling undernutrition effectively. The study advocates for integrating nutrition-sensitive actions across various sectors, not just the health sector.

Recommendations

1. Make WASH activities more nutrition-sensitive:

   • Improve the quality of water and sanitation facilities to ensure they are safe and effective in preventing contamination.
   • Strengthen hygiene promotion efforts, including increasing the availability and use of handwashing stations.

2. Improve nutrition activities within the health sector:

   • Enhance the effectiveness of National Nutrition Services (NNS) by exploring alternative service delivery mechanisms.
   • Transition from IMCI&N corners to more outreach-based platforms like "well-child spots" to better serve all segments of the population.

3. Enact a multisectoral response to undernutrition:

   • Encourage cross-sectoral collaboration and alignment of efforts to reduce undernutrition.
   • Promote nutrition-sensitive policies across sectors such as education, agriculture, and local government.

Key Information

• Tropical/Environmental Enteropathy is a physiological condition that affects nutrient absorption and is linked to chronic exposure to fecal matter.
• WASH interventions are crucial for reducing undernutrition, but they must be complemented with improved food quality, childcare practices, and behavioral change.
• Hygiene promotion is vital but currently underdeveloped, with the DPHE (Department of Public Health and Engineering) focusing mainly on infrastructure rather than behavior change communication (BCC).
• Government financing and routine monitoring are needed to ensure the sustainability of WASH programs.
• Political stewardship and intersectoral coordination are key to achieving long-term improvements in nutrition and WASH outcomes.

Structure of the Report

• Chapter 1 provides an introduction, background, rationale, and objectives.
• Chapter 2 discusses the need for coordinated multisectoral responses to undernutrition.
• Chapter 3 examines the pathways and impacts of WASH on nutrition.
• Chapter 4 outlines the achievements and challenges in the WASH sector.
• Chapter 5 presents the conclusions and recommendations.
• Appendices include detailed policies, strategies, and interventions in the WASH sector.
• Glossary and bibliography are provided for clarity and reference.

Conclusion

The study concludes that while WASH improvements are important, they must be part of a broader, multisectoral approach to effectively address undernutrition in Bangladesh. The health sector must lead, but other sectors must also adopt nutrition-sensitive policies. Hygiene promotion is critical, and behavior change communication needs to be prioritized. The government must ensure funding, coordination, and political will to support these efforts.
