Volume 18, Issue 5 (8-2015)
Abstract

Background: Exclusive breastfeeding for the first six months after delivery plays a crucial role in preventing infants morbidity and mortality. Exclusive breastfeeding intention during pregnancy is one of predictors of this behavior. Determining the effective factors in exclusive breastfeeding intention helps plan for promoting breastfeeding intention and behavior. The aim of this study is to determine predictive factors of exclusive breastfeeding intention in pregnant women, based on the theory of planned behavior.

Materials and Methods: This analytical study was conducted in 2014 on 224 primigravide women referred to Health Centers of Kashan. The samples were randomly selected from 16 health centers. The mothers completed the questionnaires of demography, intention, attitude, subjective norms and the perceived behavior control. A linear regression analysis was used to identify independent predictors of the exclusive breastfeeding intention.

Results: In regression model, the perceived behavior control (&beta=0.42, p<0.001), attitude (&beta=0.27, p<0.01) and subjective norms (&beta=0.18, p=0.059) were predictors of the exclusive breastfeeding intention. This model could explain 63% of the variance of the exclusive breastfeeding intention. The knowledge and demographic factors were not predictors of the intention.

Conclusion: The results reveal the perceived behavior control, attitudes and subjective norms could predict exclusive breastfeeding intention, so they should be considered as general guidelines in designing educational interventions in order to improve exclusive breastfeeding in women.

Volume 18, Issue 11 (2-2016)
Abstract

Background: Today, the consumption of junk food as a snack among children, especially in elementary school students is on the rise. This research has measured Theory of Planned Behavior constructs in this field.

Materials and Methods: This is a cross-sectional and analytical study that was carried out on 217 primary school students in Arak city in 2015. Students were selected according to cluster sampling method. Data collection instrument was a researcher-developed questionnaire consisting of theory of planned behavior constructs such as attitudes, subjective norms, perceived behavioral control, behavioral intention and performance. Reliability and validity of the questionnaire was studied before the study. Multivariate linear regression model was used to determine the most important predictive constructs of students behavior.

Results: In this study, the mean and standard deviation score of attitude (75.41±12.42), subjective norm (78.25±11.20), perceived behavioral control (63.69±17.06), behavicral intention (76.26±15.44), and performance (48.84±24.44) were observed. Based on the results, perceived behavioral control could predict 23 percent change in behavior. There was a direct correlation between the score of constructs and performance(p<0.05). Moreover, there were not any significant differences(p>0.05) between students nutrition and age(r=0.019), weight (r=0.07), height (r=0.12) and BMI (r=0.07).

Conclusion: The results of this study suggested that positive attitude and self-esteem must taken into account to control students diet, in the design of interventions to prevent consuming junk food.

Volume 21, Issue 5 (10-2018)
Abstract
Background and Aim: Iron deficiency is one of the most common nutritional problems during pregnancy. The purpose of this study was to assess the theory of planned behavior structures on nutritional prophylactic treatment of anemia in pregnant women of Arak city in 2018.
Materials and Methods: This is a cross-sectional study that was carried out on 199 pregnant women in Arak city using simple random sampling in 2018. The data were gathered with valid and reliable researcher-made questionnaire including demographic information and the theory of planned behavior structures. The study was conducted to determine the most important predictive constructs of pregnant womens’ behavior using a multivariate linear regression model.
Findings: The finding showed that mean age of mothers was 28.81 ± 5.1 years and the mean weekly gestation was 28.04 ± 8.9 weeks and the gestational interval with previous pregnancy was 5.18 ± 3.9 years. Mean±standard deviation of attitude score (3.61 ± 0.62), subjective norm (3.60 ± 0.74), perceived behavior control (3.50 ± 0.58), behavioral intention (3.49 ± 0.61), performance (3.55 ± 0.76) and awareness (0.57±0.2) were observed. Linear regression model showed that the performance score of pregnant women improved for each unit of attitude and subjective norms and perceived behavioral control, respectively, by 0.463, 0.343 and 0.347, respectively.
Conclusion: The results emphasize the provision of educational programs on the prevention of anemia in pregnant women with an emphasis on attitudinal structures, mental norm, and perceived behavioral control. It is suggested that at the time of designing interventions to improve the prevention of anemia in pregnancy, the structures of the theory of planned behavior should be considered.

Volume 23, Issue 6 (11-2020)
Abstract
Background and Aim: Iron deficiency is among the most prevalent nutritional problems during pregnancy. Besides, it can significantly affect pregnant women’s health. Therefore, this study aimed to determine the effect of education based on the Theory of Planned Behavior (TPB) on promoting anesthetic prevention nutritional behaviors in the pregnant woman.
Methods & Materials: This was an educational randomized controlled trial study. In total, 80 pregnant women were randomly divided into two groups of test and control (n=40/group). Data collection with reliable and validity questionnaire consist of demographic factors, knowledge, the construct of TPB (attitude, subjective norms, perceived behavior control, intention), and performance. Before performing the intervention, pre-test data were collected from the study groups. Then, the educational intervention was performed based on the results of the needs assessment for the test group, within a month and in the form of four 60-minute training sessions based on the TPB. The results were collected 3 months after the intervention and analyzed using the Mann-Whitney U test, Chi-squared test, and correlation coefficient.
Ethical Considerations: The present study was registered with the code IRCT2017052334106N1 in the Clinical Trial Registration Center of Iran and was approved by the Research Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1395.445).
Results: The present research results indicated that before the intervention, all variables were the same in the study groups. However, after the intervention, the research groups significantly differed concerning all the studied structures (P<0.05). Moreover, the Mean±SD pre-test performance score of the intervention group was equal to 2.88±0.415 (out of 5); accordingly, it was significantly improved after training to 3.64±0.216 (P<0.001).
Conclusion: Educational intervention based on the TPB improved anesthetic anxiety behaviors in the studied pregnant women; such a modification can be attributed to the provided educational program in the intervention group.
