Aims: This study assessed the impact of the JUMINTEN TABAH intervention on anemia-related knowledge, adherence to iron-folic acid supplementation, and hemoglobin levels among adolescent girls.
Materials & Methods: This quasi-experimental study, employing a nonequivalent control group with pretest-posttest measurements, was conducted between January and August 2025 in selected public senior high schools in Muaro Jambi District, Jambi Province, Indonesia. One hundred female students aged 15-18 years participated and were assigned to either intervention or control groups at the school level. The intervention incorporated structured weekly iron-folic acid intake, educational reinforcement, reminder tools (including a Friday calendar and a pocket handbook), and peer monitoring facilitated by Youth Red Cross cadres. The comparison group received routine school-based iron-folic acid distribution and standard health education. Data were obtained using validated questionnaires and hemoglobin assessments. Statistical analyses included paired and independent t-tests with effect size estimation.
Findings: The intervention group’s knowledge scores increased from a baseline of 55.40±7.25 to 78.20±8.10 post-intervention (p<0.001). Adherence scores in the intervention group rose from 54.50±7.10 to 77.40±7.95 (p<0.001). In contrast, the control group experienced modest, non-statistically significant changes: knowledge scores increased from 56.10±7.40 to 60.20±6.85 (p=0.056), and adherence scores increased from 55.20±7.25 to 59.10±6.70 (p=0.056). Between-group analysis confirmed substantially greater gains in both knowledge and adherence among students receiving the JUMIN TEN TABAH model (p<0.001).
Conclusion: The development of the JUMIN TEN TABAH model is effective in improving knowledge and compliance behavior regarding iron-folic acid tablet consumption among female adolescents in high schools in Muaro Jambi Regency.
