Efforts to build iron stores in adolescent girls will help them improve their prepregnancy hemoglobin level. To assess the effectiveness of school-based supervised weekly, bi&ndash;weekly, and daily regimen of iron folic tablets in the treatment of anemia among adolescent girls.</p><p><strong>Methods: </strong>This randomized clinical trial included 331 anemic school going adolescent girls of Shimla district of North India. Study subjects were randomized to once weekly, bi&ndash;weekly, and daily iron folic acid regimen group. An intent-to-treat approach was used to analyze the change in hemoglobin level and serum ferritin levels at the end of the trial period.</p><p><strong>Results: </strong>The rate of change of hemoglobin and serum ferritin levels from baseline to the end of the intervention was found to be similar in all the three groups (<em>P </em>= 0.64 and 0.98 for change in hemoglobin and serum ferritin). Bi-weekly treatment regimen results in comparatively more increase in hemoglobin levels (3.1 g/dl) as compared to once weekly (2.4 g/dl) and daily groups (2.3 g/dl) (ANOVA F statistics = 6.08, <em>P </em>= 0.003). Among the study subjects who reported side effects, more were from daily regimen group (55%) as compared to intermittent regimen group (25% in bi-weekly group; 18% in weekly group; <em>P </em>&lt; 0.001).</p><p><strong>Conclusions: </strong>In Shimla hills of North India, school-based intermittent iron-folic acid therapy is a feasible and effective intervention for increasing hemoglobin and serum ferritin levels of anemic adolescent girls.</p><p><strong>Keywords: </strong>Adolescent girls, anemia, intermittent, iron folic acid</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/1439http://ijpm.mui.ac.ir/index.php/ijpm/article/download/1439/1727
