<![CDATA[Background: Low body weight (underweight) in toddlers remains a nutritional challenge in Indonesia, with a national prevalence reaching 16.9% in 2024. Local food-based Supplementary Feeding (PMT) is one of the government-recommended nutrition intervention strategies to address this problem in an affordable and sustainable manner. Objective: This study aimed to determine the effect of local PMT in the form of chicken nuggets enriched with egg and vegetables on changes in body weight among underweight and at-risk-of-underweight toddlers in the working area of UPTD Puskesmas Topoyo in 2025. Methods: This study used a pre-experimental design with a one-group pretest-posttest. The sample consisted of 35 underweight toddlers who received local PMT for 28 days. Data were analyzed using the Wilcoxon Signed Rank Test to examine differences in body weight before and after the intervention, and the Mann-Whitney U test to analyze the relationship between PMT consumption compliance and the magnitude of weight gain. Results: Mean body weight increased from 9.2 kg (SD=2.1) to 9.8 kg (SD=2.2) after 28 days of intervention, with a mean increase of 0.6 kg (SD=0.6). The Wilcoxon test showed a significant difference between body weight before and after PMT administration (p=0.000). A total of 85.7% of toddlers were classified as compliant in consuming PMT (≥75%), but no significant difference in weight gain was found between compliant and non-compliant toddlers (p=0.536). Conclusion: Local PMT had a significant effect on increasing the body weight of underweight and at-risk-of-underweight toddlers within a 28-day period, so it can be considered as a routine nutrition intervention program at the community health center, while still taking into account the need for a longer intervention duration to achieve a comprehensive improvement in nutritional status.]]>
