Patterns of the triple burden of childhood malnutrition in Ecuador by age, sex, ethnicity, and poverty: a cross-sectional population survey
<h2>Summary</h2><h3>Background</h3> The triple burden of malnutrition (TBM)— the coexistence of undernutrition, overweight, and micronutrient deficiencies such as anaemia—is a growing public health challenge in low- and middle-income countries. Amid Ecuador's rapid nutrition transition, we examined the prevalence of TBM and its components among preschool children and assessed inequalities by sociodemographic characteristics and poverty. <h3>Methods</h3> We analysed nationally representative data from the 2022–23 National Survey on Child Undernutrition among children aged 0–59 months. Nutritional outcomes were defined using WHO standards. Weighted bi-probit, logistic and ordinal logistic regression models were used to examine associations between malnutrition and child, maternal, household characteristics and poverty indicators, adjusting for demographic factors. <h3>Findings</h3> Stunting or wasting affected 17.1% (95% CI: 17.2–19.1) of children under 5 (n = 1,293,325), initially higher in boys, then shifting to girls by age three, with the highest prevalence among Indigenous children. Overweight prevalence was 4.9% (95% CI: 4.5–5.4), higher in boys, and highest among White children aged 18–53 months. Coexistence of undernutrition and overweight affected 0.6% (95% CI 0.5–0.7) or ∼7760 children, primarily boys under three. Among children aged 6–59 months (n = 1,172,450), severe anaemia affected 14.8% (95% CI 13.9–15.7) and 0.33% (95% CI 0.24–0.40; n=3869) experienced TBM, disproportionately among socially disadvantaged Indigenous and Afro-Ecuadorian boys under three. <h3>Interpretation</h3> Childhood malnutrition in Ecuador exhibits overlapping, socially patterned, and spatially clustered burdens, concentrated in early childhood. Addressing TBM requires integrated, early, equity-focused "triple-duty" targeted strategies that concurrently tackle undernutrition, overweight, and anaemia as interconnected manifestations of structural inequities. <h3>Funding</h3> This research was funded by the NIHR (grant NIHR134801) using UK international development funding from the UK Government to support global health research.
