Insights
Child malnutrition, specifically wasting, significantly increases the risk of prolonged illness. Conversely, frequent illness exacerbates stunting, highlighting a critical cycle impacting child health.
Area of Science:
- Pediatrics
- Public Health
- Nutrition Science
Background:
- Limited evidence exists on the bidirectional relationship between child morbidity and under-nutrition.
- Childhood malnutrition and illness form a detrimental cycle affecting long-term health outcomes.
Purpose of the Study:
- To investigate the two-way association between morbidity and nutritional status in children under five.
- To explore the cyclical relationship between wasting, stunting, and illness duration over 24 months.
Main Methods:
- Longitudinal study design with four data collection periods over 24 months.
- Nutritional status assessed via anthropometric z-scores; morbidity measured by sick days.
- Mixed-effects models used to analyze the interchanged dependency between morbidity and nutritional status, adjusting for covariates.
Main Results:
- Wasted children (8.9% prevalence) were 35% more likely to experience prolonged illnesses (OR: 1.35).
- Children with high morbidity (frequent sick days) were 64% more likely to become stunted (29.9% prevalence) (OR: 1.64).
- Multiple anthropometric failures observed in 21.3% of children.
Conclusions:
- Acute illness appears to partly explain the link between wasting and stunting.
- Wasting elevates the risk of prolonged illness, which in turn elevates the risk of stunting.
- Interventions targeting both malnutrition and illness are crucial for breaking this cycle.
Abstract:
Even though limited evidence is available, the relationship between morbidity and under-nutrition among children under-five is likely to be a strong two-way association. This study aims to explore this vicious cycle by employing longitudinal data of four periods within a 24 month follow-up, whereby morbidity was captured between two subsequent anthropometric measures. Malnutrition was classified according to z-scores of anthropometric measures and morbidity by number of sick days experienced inbetween. Mixed-effects models were used to assess this relation, where dependency of morbidity and nutritional status were interchanged; models were adjusted for province, age, gender, wealth index score, maternal education level, diet, and Water, Sanitation, and Hygiene indicators. Stunting and wasting prevalences were 29.9% and 8.9%, respectively, where 21.3% of the children hadmultiple anthropometric failures. Children identified as wasted were 35% more likely to experience prolonged illness periods (OR: 1.35, 95% CI: 1.02-1.56). Those experiencing high proportion of sick days were found to be 64% more likely to become stunted (OR: 1.64, 95% CI: 1.18-2.29). This study suggests that the link between wasting and stunting could be partly explained by acute illness, where wasting increases the likelihood of prolonged epiosed of illness, which increases the risk of stunting.
