Abstract

Background: Iron deficiency anemia (IDA) is one of the most common problems during pregnancy. The aim of this research was to determine the effect of educational program based on Theory of Planned Behavior (TPB) on promoting nutritional behaviors preventing anemia in a pregnant woman in Shiraz city, Iran.

Methods: This quasi-experimental study was done on 150 pregnant women (75 experimental and 75 control groups) who were selected using randomly sampling method in in Shiraz city, Iran, in 2020-2021. The educational intervention for the experimental group included six educational sessions for 50 or 55 min-based TPB model. A questionnaire consisted of items about demographic information, TPB constructs (attitude, perceived behavioral control, subjective norms and behavioral intention) was used to measure the nutritional behaviours preventing iron deficiency anemia in pregnancy women before and 3 months after the intervention.

Results: The results showed that before the educational intervention, there was no significant difference between the two groups in terms of knowledge, attitude, perceived behavioral control, subjective norms, behavioral intention and nutritional performance; however, three months after the educational intervention, the experimental group showed a significant increase in each of the mentioned variables. For example the mean and standard deviation score of behavioral intention after intervention in the experimental group was significantly increased (25.57 ± 1.66, P = 0.001),and the mean and standard deviation score of performance after intervention in the experimental group was significantly increased (31.03 ± 2.19, P = 0.001), (P < 0.05).

Conclusions: After the educational intervention, the experimental group showed a significant increase in of the knowledge, attitude, perceived behavioral control, subjective norms, behavioral intention and nutritional performance. Therefore the results of the study showed positive effect of nutrition educational intervention program base on TPB model on improvement of iron deficiency anemia preventive behaviours in the pregnancy women.
