Risk factors for wasting and stunting among children in Metro Cebu, Philippines
Insights
This study on child malnutrition in the Philippines found that maternal factors primarily influence wasting and stunting in infants under six months. After six months, socioeconomic factors become key determinants of malnutrition risk.
Area of Science:
- Pediatrics
- Public Health
- Nutritional Epidemiology
Background:
- Child malnutrition, specifically wasting and stunting, remains a significant global health challenge.
- Understanding the distinct risk factors for wasting and stunting is crucial for effective interventions.
- Previous research suggests differing etiological pathways for wasting and stunting.
Purpose of the Study:
- To identify and analyze the risk factors associated with wasting and stunting in young children (under 30 months) in Metro Cebu, Philippines.
- To differentiate the determinants of wasting and stunting based on child age and socioeconomic context.
- To inform targeted public health interventions for child malnutrition.
Main Methods:
- Longitudinal study design involving 18,544 children under 30 months in Metro Cebu, Philippines.
- Cross-sectional analysis of demographic, socioeconomic, maternal, and child biological variables.
- Logistic regression modeling applied to six child age-residence strata.
Main Results:
- Wasting and stunting appear to be distinct nutritional processes with different risk factor profiles.
- For infants under 6 months, maternal behaviors (e.g., breastfeeding) and child biological factors (e.g., birth weight) were primary risk factors.
- After 6 months, household socioeconomic characteristics (e.g., father's education, media access) became significant determinants of malnutrition.
- Socioeconomic influence on stunting risk emerged earlier in rural than urban settings.
Conclusions:
- Maternal and child biological factors are critical in early infancy, while socioeconomic status gains importance later in childhood.
- Interventions should be age-specific, addressing maternal and infant factors early, and socioeconomic determinants in older infants.
- The findings highlight the complex interplay of biological, behavioral, and socioeconomic factors in child malnutrition.
Abstract:
Risk factors for wasting and stunting were examined in a longitudinal study of 18 544 children younger than 30 mo in Metro Cebu, Philippines. Measures of household demographic and socioeconomic characteristics, maternal characteristics and behavior, and child biological variables were analyzed cross-sectionally in six child age-residence strata by using logistic regression. Our results support biological and epidemiologic evidence that wasting and stunting represent different processes of malnutrition. They also indicate that the principal risk factors for stunting and wasting in infants < 6 mo of age were either maternal behaviors or child biological characteristics under maternal control, eg, breast-feeding status and birth weight. After 6 mo of age, household socioeconomic characteristics emerged with behavioral and biological variables as important determinants of malnutrition, eg, father's education and presence of a television and/or radio. Household socioeconomic status influenced the risk of stunting earlier in rural than in urban barangays. Implications of the results for interventions are discussed.
