Nutritional and environmental risk factors for diarrhoeal diseases in Ecuadorian children
Insights
Diarrhoea prevalence in Ecuadorian children under 5 is highest in 6-23-month-olds, linked to poor sanitation and hygiene. Nutritional status, particularly low weight-for-age, also impacts diarrhoea risk in better hygienic settings.
Area of Science:
- Pediatrics
- Public Health
- Nutrition Science
Background:
- Diarrhoea remains a leading cause of child mortality globally.
- Understanding risk factors is crucial for effective prevention strategies.
- Previous studies highlight the interplay between hygiene, nutrition, and child health.
Purpose of the Study:
- To identify risk factors for diarrhoea in Ecuadorian children under 5 years old.
- To examine the association between diarrhoea, hygiene, and nutritional status.
- To investigate age-specific variations in diarrhoea prevalence and risk factors.
Main Methods:
- Cross-sectional study of 1,620 Ecuadorian children under 5.
- Data collection included recall of recent diarrhoea episodes, demographic information, and environmental hygiene factors.
- Nutritional status assessed via anthropometry (weight-for-age Z-score) and blood chemistry (serum retinol, zinc).
Main Results:
- Diarrhoea prevalence peaked in children aged 6-23 months.
- Hygiene factors (water quality, sanitation, refuse disposal) were significantly associated with diarrhoea in this age group.
- Low weight-for-age Z-scores and low serum zinc were associated with diarrhoea in children with better sanitation.
- Multivariate analysis confirmed associations between sanitation, anthropometric nutritional status, and diarrhoea.
Conclusions:
- Hygiene and sanitation are critical determinants of childhood diarrhoea in Ecuador.
- Nutritional status, particularly anthropometry, plays a significant role, especially in environments with improved hygiene.
- Targeted interventions addressing both sanitation and nutritional support are essential for reducing diarrhoea burden in young children.
Abstract:
Risk factors associated with diarrhoea, based on the recall of a recent episode were evaluated from a cross-sectional national nutrition and health study in 1,620 Ecuadorian children less than 5 years old. Prevalence of diarrhoea varied with the age of the children; 6- to 23-months-old children showed the highest prevalence. In this age range the prevalence of diarrhoea was significantly associated with hygienic factors (quality of drinking water, sanitation and refuse system), but not with demographic factors (sex, altitude, population density, family size). The nutritional status of the children was determined by anthropometry and blood chemistry. After stratification for sanitation levels, a low weight-for-age Z-score and low serum retinol and zinc concentrations showed a statistically significant (p < or = 0.06) association with diarrhoea prevalence only in children living under better hygienic conditions. Multivariate analysis revealed significant associations between both sanitation levels and nutritional level as defined by anthropometry, but not by blood chemistry, and diarrhoea prevalence.
