THE EFFECTIVENESS OF GENTING VIDEOS THROUGH TIKTOK ON ADOLESCENT GIRLS' REPRODUCTIVE HEALTH KNOWLEDGE IN STUNTING PREVENTION

Abstract

Background: Stunting is a public health issue that remains a serious challenge in Indonesia, including in Riau Province, with long-term impacts on the quality of human resources. Prevention of stunting needs to begin in adolescence, as knowledge of reproductive health plays an important role in preparing for a healthy pregnancy and childbirth. Objective: This study aims to determine the effectiveness of Genting (Generation Without Stunting) videos via the TikTok application on adolescent girls' reproductive health knowledge in preventing stunting. Methods: The study used a quasi-experimental design with two groups, employing a pre-test and post-test approach in the experimental and control groups. A total of 200 respondents were selected using stratified random sampling, with 100 respondents in each group. The research instrument consisted of a validated reproductive health knowledge questionnaire. Data analysis was performed using univariate and bivariate analysis with the Wilcoxon and Mann-Whitney tests. Result: The results showed a significant increase in the experimental group with a p-value of 0.000 (<0.05), while the control group showed no significant change (p=0.120). The Mann-Whitney test showed a significant difference between the two groups (p=0.000). Conclusion: Videos posted on TikTok have proven effective in improving adolescent girls' knowledge of reproductive health and have the potential to contribute to early stunting prevention efforts. TikTok-based health education should be further developed, supported by active community involvement, and examined in future studies using additional variables.
