title: An assessment of the role of perceived benefits, barriers and self-efficacy in predicting dietary behavior in male and female high school students in the city of Izeh, Iran.
abstract: BACKGROUND
  Paying attention to improving the nutritional status of adolescents can be one of the most effective fundamental measures for preventing chronic diseases, particularly cardiovascular diseases in later life. Identifying the predicting elements in different behaviors is one of the most effective ways that can be considered in prevention programs in different communities, particularly in developing countries. The purpose of was to determine the perceived efficacy, benefits and barriers related to a healthy nutrition pattern and the relation of these variables with a healthy diet in male and female high school students in Izeh city.
  
  
  METHODS
  In this cross-sectional descriptive and analytic study conducted throughout high schools in Izeh City, the subjects were 500 students (300 girls and 200 boys) from the 1390-91 school years who were selected through the multistage random sampling method; the acquired data was then studied and analyzed. The data for this study was gathered through a multi-sectional questionnaire (that included demographic characteristics, self-efficacy, perceived benefits and barriers). The Independent t-test, Spearman's Correlation, Pearson's Correlation Coefficient and Linear Regression were used to interpret and analyze the data.
  
  
  RESULTS
  Data analysis showed that the mean age of male participants was 15.67 ± 0.95 years and females 15.86 ± 1.16 years. The mean score for healthy eating patterns in male students was 46.83 ± 14.86 and in female students 44.20 ± 14.16 respectively. The mean score for perceived benefits of healthy eating in girls was significantly higher than that in boys. There was a direct meaningful relationship between the mean score of benefits and perceived self-efficacy with the healthy eating behaviors in the two sexes, (P < 0.001). The results of the multiple linear regression analysis revealed that the most important predictive factors in the students' healthy eating behavior are self-efficacy and perceived benefits respectively and that perceived barriers is not an influencing predictor in healthy eating patterns.
  
  
  CONCLUSIONS
  The results of this study showed that many factors influence students' diet pattern and undeniably the role of these factors are not alike in the two sexes. The results also showed that perceived self-efficacy and benefits of healthy nutrition strengthens healthy eating behavior in students and thus these factors should be considered by health authorities in the country in any future programming.
