Abstract

Introduction: Given the importance of adolescent health, especially for girls, and the inadequacy of dairy consumption around the world, there is a need to examine the psychological factors associated with dairy behavior. Therefore, this study was performed on high school girls.

Methods: Descriptive-analytical research was performed on 385 female high school students in Shaft city in the academic year of 2019 in the census method. The survey questionnaire consisted of demographic information, knowledge structure, perceived self-efficacy, and dairy consumption behavior completed by students. To analyze the results, 21 SPSS software and Chi- Square tests, Spearman correlation coefficient and multiple logistic regression were used.

Results:n total, 221 people (57.7%) consumed less than 2 units and 162 people (42.3) consumed more than 2 units per day of dairy products. The average score of self-efficacy structures was 23.20 ± 6.6 (average) and knowledge 19.1± 3.05 (at a good level). There was no significant correlation between perceived self-efficacy and dairy consumption behavior r = 0. 199, but significant p <0.05, and no significant correlation was observed between knowledge and behavior (p> 0.05, r =- 0.25). The results of multiple logistic regression showed the predictive power of the perceived self-efficacy structure in dairy consumption behavior with a chance ratio of 1.052 (with a confidence interval of 95%: 1.089-1.016).

Conclusion:Understood self-efficacy predicted the behavior of dairy consumption in the students studied, educational interventions in schools should focus more on promoting perceptions and nutritional attitudes.
