[摘要] Background: Inadequate nutritional intake can affect the body condition of young women, one of effects is increasing the incidence of anemia. The Health Belief Model theory can determine how a person will behave in deter­mining the nutritional intake consumed every day, especially foods that can prevent anemia. This study aimed to determine the effect of the iron-supplemented program, intra­personal and social factors on nutritional intake for anemia prevention among female adolescents in high school in Yogyakarta. Subjects and Method: This study was an observational analytic study with a cohort retrospective approach. The sample was select­ed by purposive sampling with a sample size of 120 study subjects. Data were analyzed using multilevel linear regression analysis with the Stata 16 program. Results: Nutritional intake for anemia pre­vention in female adolescents has increased with the iron supplement program (b= 0.24; 95% CI= 0.15 to 0.32; p<0.001), high family income (b= 0.16; 95% CI= 0.07 to 0.24; p= 0.001), high perceived susceptibility (b= 0.11; 95% CI= 0.02 to 0.20; p= 0.012), high per­ceived seriousness (b= 0.66; 95% CI= 0.56 to 0.76; p<0.001), and high perceived benefit (b= 0.23; 95% CI= 0.13 to 0.33; p<0.001). Nutri­tio­nal intake for the prevention of anemia among adolescent decreased with high perceived barrier (b= -0.09; 95% CI= -0.17 to -0.01; p= 0.040). There was no contextual effect of school on nutritional intake for anemia prevention among female adolescent (ICC=4.57%). Conclusion: There was an effect of the blood-supplemented program, family income, and the Health Belief Model construct (perceived susceptibility, perceived seriousness, perceived benefits and perceived barriers) on nutritional intake for anemia prevention among female adolescent.
