Background: Stunting remains one of the most significant nutritional status issues among wasting, underweight, and obesity that endangers children's growth and development. Father involvement in parenting in Indonesia is still relatively low parenting patterns that mothers solely carry out without involving fathers will affect the child's nutritional status, as this can occur due to the lack of monitoring received by the child. This study aims to analyze the association between father involvement in feeding and stunting prevalence in children aged 24-59 months in families in Jember Regency.

Materials and Method: This research design uses a descriptive analytic approach with a cross-sectional method. Data collection was conducted using the IYCF questionnaire to determine the level of father's involvement in feeding, while the stunting status was measured using a digital scale and microtoise. The sample for this study consisted of 212 father-child pairs, where the unit of analysis was the father-child pair. Stratified random sampling technique across villages and posyandu was used in this study. Data were analyzed using the Chi-square test to determine the unadjusted bivariate association between variables.

Results: The research findings indicate that 52% of fathers have low involvement in feeding children. Stunted children categorized as stunted (-3≤"HAZ"<-2) accounted for 70.8%, while 29.2% fell into the severely stunted ("HAZ"<-3)category. The unadjusted bivariate chi-square test results showed a significant association (χ^2=5.599; p-value = 0.018).

Conclusion: This study provides evidence of the protective association of fathers’ involvement in child feeding practices with stunting status, underscoring the need for education and empowerment programs targeting fathers as a strategy to address stunting.
