Children at risk of developing dehydration from diarrhoea: a case-control study

Area of Science:

• Pediatrics
• Public Health
• Infectious Diseases

Background:

• Diarrhea remains a leading cause of dehydration in young children globally.
• Identifying specific risk factors for dehydration is crucial for effective prevention and management.

Purpose of the Study:

• To pinpoint factors associated with dehydration in Bangladeshi children under two years old presenting with diarrhea.
• To develop a predictive model for identifying children at high risk of developing diarrhea-associated dehydration.

Main Methods:

• A hospital-based case-control study involving 80 cases with dehydration and 160 age-matched controls without dehydration.
• Data collection included clinical examination and maternal interviews, with a 14-day follow-up.
• Statistical analysis employed bivariate analysis and stepwise logistic regression to identify significant prognostic factors.

Main Results:

• Seventeen of thirty-eight studied factors were significantly associated with dehydration development.
• A combination of vomiting, inadequate home oral rehydration therapy, poor maternal hygiene (dirty fingernails), and long distance (>3 km) to the hospital showed high predictive accuracy (77.5% sensitivity, 91.2% specificity).

Conclusions:

• Vomiting, lack of home oral rehydration therapy, maternal hygiene, and distance from healthcare facilities are significant predictors of diarrhea-associated dehydration in young children.
• These identified prognostic factors can empower community health workers to recognize high-risk children and implement targeted preventive strategies.
