Background: IDA is a preventable disease but its consequences can't be prevented or treated easily. Aim of the study: to evaluate the impact of management protocol on pregnant women with IDA using health promotion model (HBM) through changing their perception and behavior regarding the risk of IDA. Subjects and Methods: Research design: A quasi-experimental design. Setting: the study was carried out in El-nahaal MCH Center in Zagazig. Subjects: a representative sample of 180 pregnant women diagnosed with IDA . Tools of data collection: Six tools were used in data collection namely: An interview questionnaire form, Assessment of women knowledge, Observation checklist for assessing women dietary habits and cooking practices, HBM constructs, follow up assessment record & an educational health program. Results: According to their mean hemoglobin level before and after the intervention, it is obvious that the mean hemoglobin level did statistically increase (p=0.001*) among the study group after the second and third visit compared to those in the control group, There's was statistically significant improvements in the mother knowledge about IDA at the post-test from only 7.0% at the pre-test to the majority of women (85.0%) at the post-test compared to those in the control group. Statistically significant improvements in the study group at the post-test regarding the level of perception about IDA compared to those in the control group. Conclusion: low level of perceiving risk of IDA is associated with poor dietary practices as a preventive behavior. Using HBM to change pregnant women's behavior and dietary practices; produce significant changes at post intervention assessment, in the level of pregnant women's perceptions regard the risk of iron deficiency anemia. Recommendations: further study should be conducted, using a sample with a large size, different levels of IDA and in different geographical settings to generalize the study result.
