Objectives: Maternal nutritional behavior before and during pregnancy plays an important role in improving the pregnancy outcomes and the health of newborns after birth. The theory of planned behavior is an appropriate model for use in pre-pregnancy and pregnancy.This study examined the effect of the Theory of Planned Behavior education on Nutritional Behaviors of Overweight and Obese Women before pregnancy
Materials and Methods: This randomized controlled trial was conducted on 100 overweight and obese women who were referred to a nutrition unit in Khansar city. Sampling method was convenient and samples were randomly assigned to two groups. Intervention group in addition to routine care, received 5 nutritional training sessions based on the theory of planned behavior. Data were collected with TPB questionnaire and nutritional behaviors questionnaire.Data were collected before, after and two month after education.The student t test, Fisher exact test,Mann -Whitney U test, chi-square test and Repeated-measure test were used for data analysis.
Results: The result of repeated measure test showed that the overall score of the theory of planned behavior over time was changed (P = 0.002), and there was a significant difference between the two groups (P = 0.002). The result of repeated measure test showed that the length of time affects the nutritional behavior score (P = 0.000) and there was a significant difference between the two groups (P=0.000).
Conclusion: Considering the effect of training based on the theory of planned behavior on nutritional behavior, it is suggested that the content of this training be included in the pre-pregnancy program.
