Objective: To examine the effect of nutritional program based on Pender's Health Promotion Model on nutritional behaviors of pregnant women referred to health centers in Hamadan city, Iran.
Methodology: This was a quasi-experimental study. Hundred pregnant women (primigravidae) referred to health centers in Hamadan city, Iran, from October 2015 to March 2016 were randomly assigned to two groups (study and control). Nutritional program was presented within 04 sessions in two weeks. Data were gathered using three-part (demographics, program and nutritional behavior) questionnaire. Four nutritional program sessions were carried out in the study group. Assessment was done in three steps (before, immediately, and six weeks later to interposition). Processing of the data was carried out by SPSS version16 and ANOVA was used to compare the groups.
Results: The mean scores of the two groups were matched based on Pender's Health Promotion Model (HPM). The scores after the intervention in both nutritional behaviors and Pender's HPM components improved as compared to control group (p <0.001).
Conclusion: There was significant difference between the scores on various components after the Pender's HPM based nutritional education on nutritional behavior of pregnant women in the study group as compared to control group.
