Background: Stunting remains one of the crucial public health problems in Indonesia. The prevalence of stunting in East Java Province remained at 14,7% in 2024 and Sampang Regency, as one of the partner regions of Politeknik Negeri Madura, is included among the priority areas for stunting intervention, with a stunting prevalence of 18,5% in 2025.Objectives: This study aimed to assess changes in knowledge and attitudes toward stunting prevention after video-based health education among female students at Politeknik Negeri Madura.Methods: This study employed a quasi-experimental design with a one-group pretest-posttest approach. The study was conducted among 100 female students selected through purposive sampling at Politeknik Negeri Madura in October 2025. The intervention consisted of a 15-minute educational video covering topics on stunting, its risk factors, prevention strategies, balanced nutrition, and the first 1,000 days of life. Knowledge and attitudes were assessed using a structured questionnaire that had been tested for validity and reliability with a Cronbach's alpha of 0.839 and was administered before and after the intervention. Data were analyzed using the Wilcoxon Signed Rank Test.Results: The study results showed an increase in the mean knowledge scores of 10.23 points, from a pretest mean score of 30.17 to a posttest mean score of 40.40, with a p-value < 0.001. Similarly, the mean attitude scores increased by 6.66 points, from a pretest mean score of 32.08 to a posttest mean score of 38.74, with a p-value < 0.001. The median knowledge score also increased from 30 (IQR = 3) to 41 (IQR = 3), indicating a statistically significant difference (Z = −8.691; effect size (r) = 0.869). Likewise, the median attitude score increased from 32 (IQR = 4) to 39 (IQR = 3), with a statistically significant difference (Z = −8.526; effect size (r) = 0.853).Conclusion: Knowledge and attitude scores toward stunting prevention increased significantly after video-based health education among female students at Politeknik Negeri Madura (p < 0.001).
