Thus, it is necessary to promote the health of this group in society by creating proper nutritional behaviors, especially the consumption of dairy products. This study was conducted with the purpose of investigating the determinants of dairy use status and effective factors on consumption behaviors on the basis of Health Belief Model among health care providers of health centers Urmia, Iran.Methodology: Throughout this descriptive-analytical study, ۳۰۳ health care providers working in the health centers of Urmia, were included in the study by the census sampling method, on the basis of inclusion criteria of the study. The instruments of data collection were researcher-made reliable and validated questionnaires in three groups of: personal profile, consumption status of different types of dairy, and health belief model (HBM). Data were collected by using the structured interviews, then ultimately analyzed by SPSS۲۴ as well as the descriptive analytical tests (ANOVA, Linear Regression).Findings: The average age of the participants was (۳۸.۵۷±۶.۳۶). Among the structures of Health Belief Model (HBM), the dimension of self-efficiency showed significant relationship with the score of the dairy consumption behavior (p=۰.۰۰۰). Additionally, there was a meaningful significant relationship between the mean score of dairy consumption behavior with the occupational status, marital status, and ethnicity (P<۰.۰۵). According to the Linear Regression Test, totally, the structures of HBM indicated ۲۰% of the variance of the dairy consumption behavior. The predicting power of perceived self-efficiency was more than other structures of the model.Conclusion: Regarding the findings of the studying the particular role of self-efficiency in promoting the dairy consumption behavior of health care providers, as well as the low effect of the Health Belief Model on predicting the dairy consumption behavior of health care providers, it is recommended to implement other health educational programs in order to promote the health status of the healthcare staff, and to improve their dairy consumption behaviors
