Insights
Children in high-risk disaster districts in Bangladesh face increased stunting and underweight. Addressing multi-hazard risks is crucial for child nutrition.
Area of Science:
- Public Health
- Environmental Health
- Pediatrics
Background:
- Child undernutrition and natural disasters are significant public health issues in Bangladesh.
- Limited research exists on the relationship between natural disaster risk and child undernutrition in the region.
Purpose of the Study:
- To assess the association between residential district multi-hazard risk and undernutrition in children under five years old in Bangladesh.
Main Methods:
- Utilized data from 22,055 children under five from the 2019 Multiple Indicator Cluster Survey of Bangladesh.
- Calculated a multi-hazard risk score based on tornado, cyclone, earthquake, and flood data.
- Categorized districts into low, moderate, and high multi-hazard risk levels.
Main Results:
- Children in high multi-hazard risk districts showed a 19% increased likelihood of stunting and a 23% increased likelihood of being underweight compared to those in low-risk districts.
- No significant association was found between multi-hazard risk and wasting in children.
- The study highlights a clear link between environmental hazards and specific forms of child undernutrition.
Conclusions:
- High multi-hazard risk districts are associated with increased stunting and underweight in children under five in Bangladesh.
- Interventions focusing on agricultural adaptation, post-disaster nutritional support, and enhanced maternal and child care are recommended.
- Mitigating disaster risks is essential for improving child nutrition outcomes in vulnerable populations.
Abstract:
Child undernutrition and natural disasters are major public health concerns in Bangladesh, but research into their relationship is lacking. This study assessed the association between residential district multi-hazard-risk and undernutrition among children aged less than 5 years (under-5) in Bangladesh. Data for 22,055 under-5 children were extracted from the 2019 Multiple Indicator Cluster Survey of Bangladesh. Multi-hazard risk was categorized as low (score<10), moderate (score 10-20), and high (score>20) using a combined score of four major hazards: tornado, cyclone, earthquake, and flood. We found that children from high multi-hazard risk districts were 19% more likely to be stunted and 23% more likely to be underweight compared to low-risk districts. However, wasting was not associated with multi-hazard risk. Strategies such as agricultural adaptation and coping mechanisms, long-term post-disaster nutritional response, extended periods of relief supports, and enhanced quality maternal and child care services may help to reduce undernutrition burdens in Bangladesh.
