An Analysis of Specific Nutritional Interventions as a Regional Development Program and Their Impact on Stunting Prevalence in Batu Bara Regency

Abstract

Stunting is a persistent public health issue in Indonesia, particularly in districts such as Batu Bara, which has historically reported high prevalence rates. This study examines the effectiveness of specific nutritional interventions—namely Vitamin A supplementation and supplementary feeding—in reducing stunting prevalence from 2021 to 2023. Utilizing a cross-sectional design, secondary data from 12 sub-districts were analyzed through multiple regression modeling using EViews version 10, employing the Fixed Effect Model to determine statistical significance. Results indicate a substantial reduction in stunting prevalence, from 30.9% in 2021 to 15.7% in 2023. Vitamin A supplementation coverage reached 87.6%, while supplementary feeding achieved 78.6% coverage. Both interventions were found to significantly contribute to stunting reduction (p < 0.05), with the most notable impact observed in Medang Deras and Ujung Kubu. These findings underscore the importance of sustained inter-sectoral coordination and community engagement to close implementation gaps and meet Indonesia’s national target of 14% by 2024.
