“…In this study, behavioral intention also showed a significant increase in the experimental group three months after the educational intervention. This is consistent with the results of other similar studies [ 8 , 17 , 19 ].…”

“…In the present study, the mean score of knowledge, attitude, subjective norms, perceived behavioral control, behavioral intention and nutritional performance in both experimental and control groups before the intervention were not statistically significant. This is consistent with the results of some other studies [ 8 , 17 , 19 , 20 ]. Perhaps the low mean score of these constructs before the educational intervention is due to the lack of codified and model-oriented training programs using participatory programs and combined educational methods [ 21 ].…”

“…Our intervention program in the present study could improve the perceived behavioral control in the experimental group. The results of this study were consistent with the results of the study by Alami et al [ 17 ]. Of course, several studies have examined this issue from different aspects.…”

“…Similar studies have also considered the role of spouses and friends in subjective norms [ 8 , 29 ]. Based on Table 4 , the mean score of subjective norms in the experimental group was significantly different after the educational intervention, which is consistent with the results of some other studies [ 17 , 19 ]. However, this is not consistent with the results of studies by Ahmadi et al [ 30 ] and Pawlak et al [ 27 ].…”

“…Of course, numerous successful studies have been conducted worldwide to improve nutritional behaviors associated with iron deficiency anemia using TPB [ 8 , 12 , 17 ]. Therefore, considering that anemia is one of the causes of maternal mortality during pregnancy and that maternal mortality is considered as one of the important indicators of the quality of health services in a country [ 18 ] And due to nutritional problems during pregnancy, including the high prevalence of anemia in Iranian pregnant women [ 3 ] and it becomes a serious concern for their health [ 4 ].…”

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.
