OBJECTIVE: The purpose of this study is to find factors affecting stunting (height/age < -2 SD; based on WHO growth chart) in North Kayong toddlers. There is no data of prevalence and factors affecting stunting among toddlers in North Kayong Health Profile before.
METHOD: This pilot study is a cross-sectional, analytical quantitative study, was held on August–December 2018 in RSUD Sultan Muhammad Jamaludin I.

Chi-square test revealed that there are significant association between preterm birth, low birth weight, incomplete immunization status, no exclusive breastfeeding, stopping breastfeeding before 2 years old, low family income, and low maternal educational status with stunting among 24-59 months old children in RSUD Sultan Muhammad Jamaludin I North Kayong (p < 0,05). Logistic regression test showed risk factor for stunting in this study were low birth weight (OR=58,340; 95% CI: 5.707-596.357) and low maternal educational status (OR=6,901; 95% CI: 1.726-27.592).
CONCLUSION: Prevalence of stunting among 24-59 months old children in RSUD Sultan Muhammad Jamaludin I North Kayong is 45,6%.
