Summary
Written by AI, not yet AICS's view · claude-sonnet-5-5The study builds a Child Stunting Risk Index from the 2023 Indonesian Health Survey to flag children aged 0–59 months who are at risk before stunting can be measured. The index combines two groups of risks: biological and infection risks, and nutrition and care risks. It is meant as a screening tool, not a diagnosis or a measure of how common stunting is. Among 82,678 children with valid scores, about one in four was classed as high or very high risk. Risk was highest among children aged 6–23 months and in Maluku-Papua, Sumatra and Sulawesi.
Key points
- Among 82,678 children with valid scores, the weighted mean index was 0.126 (12.56 on a 0–100 scale), with mean indicator coverage of 96.45%.
- 25.64% of children were classified as high or very high risk.
- Risk was highest among children aged 6–23 months and in Maluku-Papua, Sumatra and Sulawesi.
- Higher scores were consistently seen among children with low birth weight, prematurity, incomplete immunization, inadequate dietary diversity, limited growth monitoring, and suboptimal breastfeeding and feeding practices.
- Current policy and surveillance mostly identify children only after growth deficits have occurred.
Limitations
The index is a formative screening tool based on cross-sectional survey data and a sample-relative classification, so it does not diagnose stunting, estimate prevalence or show that it predicts later stunting. The abstract does not report any test of whether using it improves child outcomes.
Abstract
Indonesia has made progress in reducing child stunting, but current policy and surveillance systems largely identify children only after anthropometric growth deficits have occurred. This approach overlooks the accumulation of biological, infection, nutritional, and caregiving risks that precede measurable stunting. This study develops a Child Stunting Risk Index (CSRI) using the 2023 Indonesian Health Survey to support early and preventive risk prioritization among children aged 0–59 months. The CSRI is designed as a concurrent vulnerability screening tool rather than a diagnostic measure or an estimator of stunting prevalence. The formative index combines age-eligible proximal indicators within two dimensions: biological/infection risks and nutrition/care risks. Indicators are aggregated using nested equal weighting, subject to minimum data-coverage requirements. Risk categories are determined using a sample-relative traffic-light classification and assessed through leave-one-out known-group validation against established child growth risk markers. Among 82,678 children with valid scores, the weighted mean CSRI was 0.126 (12.56 on a 0–100 scale), with mean indicator coverage of 96.45%. Overall, 25.64% of children were classified as having high or very high risk. Risk was highest among children aged 6–23 months and in Maluku-Papua, Sumatra, and Sulawesi. Higher scores were consistently observed among children exposed to low birth weight, prematurity, incomplete immunization, inadequate dietary diversity, limited growth monitoring, and suboptimal breastfeeding and feeding practices. Theoretically, the study extends stunting assessment from outcome-based measurement to a multidimensional vulnerability framework. Practically, the CSRI provides a scalable tool for targeting preventive interventions before growth failure becomes observable.
