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.</span></span></span></span></span><br> <span style="font-size:12pt"><span style="tab-stops:7.1pt"><span new="" roman="" style="font-family:" times=""><b><span style="font-size:10.0pt"><span cambria="" style="font-family:"><span style="color:#4f81bd">Findings:</span></span></span></b> <span style="font-size:10.0pt"><span cambria="" style="font-family:">The intervention group&rsquo;s knowledge scores increased from a baseline of 55.40&plusmn;7.25 to 78.20&plusmn;8.10 post-intervention (p<0.001).
