Diarrhoea mortality in rural Bangladeshi children
1International Centre for Diarrhoeal Disease Research, Bangladesh, Dhaka.
Insights
Diarrhoea causes significant mortality in young Bangladeshi children. A comprehensive approach beyond oral rehydration therapy (ORT) is crucial for reducing child deaths from diarrhoea.
Area of Science:
- Public Health
- Epidemiology
- Pediatrics
Background:
- Diarrhoeal diseases remain a leading cause of mortality in children under five globally, particularly in rural developing communities.
- Understanding the specific types and impacts of diarrhoea is essential for effective public health interventions.
Purpose of the Study:
- To describe diarrhoeal mortality and hospital admissions in young children in rural Bangladesh.
- To evaluate the potential impact of oral rehydration therapy (ORT) versus broader strategies on reducing child mortality from diarrhoea.
Main Methods:
- Retrospective analysis of mortality and hospital admission data for children under five years old.
- Categorization of diarrhoea by type: acute watery, acute non-watery (including dysentery), and persistent diarrhoea.
- Assessment of associations between diarrhoea types, malnutrition (wasting), and mortality.
Main Results:
- Acute watery diarrhoea accounted for 5-11% of deaths in infants and young children.
- Acute non-watery diarrhoea (dysentery) was associated with 16% of deaths in children aged 1-4 years.
- Persistent diarrhoea with severe wasting was linked to 63% of diarrhoea deaths and 34% of all deaths in children aged 1-4 years.
Conclusions:
- Exclusive reliance on oral rehydration therapy (ORT) is insufficient to significantly reduce diarrhoea mortality in this population.
- A multifaceted strategy incorporating preventive measures (e.g., measles immunization, nutrition education) and improved curative care (e.g., dietary management, dysentery treatment) holds greater potential for impact.
Abstract:
Diarrhoeal mortality and hospital admissions for diarrhoea are described among children under the age of 5 years in a large rural Bangladeshi community during 1986-87. Acute watery (dehydrating) diarrhoea was associated with 11 per cent of all deaths among infants aged 1-11 months and 5 per cent among children aged 1-4 years. Acute non-watery diarrhoea, including bloody dysentery and diarrhoea with mucoid stools, was associated with 16 per cent of all deaths among children aged 1-4 years. In this age group, persistent diarrhoea, particularly when accompanied by recent and/or severe wasting, was associated with 63 per cent of all diarrhoeal deaths and 34 per cent of all deaths. These data suggest that exclusive emphasis on ORT will have little impact on diarrhoea mortality among children in rural Bangladesh. A broader strategy, both preventive and curative, including measles immunization, nutrition education, dietary management of diarrhoea, and the treatment of dysentery in the community, carries a greater potential.
