This study aims to identify the relationship between health beliefs and diabetes preventive behaviors in individuals at high-risk for developing type 2 diabetes mellitus in Taft city. A study using the Health Belief Model [HBM] framework was undertaken with 114 subjects of both genders aged 30 years and above from three urban health centers who were diagnosed as at high risk for type 2 diabetes during the screening program. Research tool was a 66-item questionnaire. Data was analyzed with descriptive statistics, Spearman correlation and Mann-Whitney U-test. Of the total, 29.8% of subjects were male and 70.2% were female. Regarding education, 68.4% of the subjects had not completed high school and 89.4% of them was married.

There were significant correlations between preventive behaviors and perceived susceptibility, r=0.243[P<0.009], perceived severity, r=0.312 [P<0.001], perceived barrier, r=0.245 [P<0.006] and perceived self-efficacy, r=0.497 [P<0.001]. Preventive behaviors among the subjects at high-risk for developing type 2 diabetes despite the presence of risk factors was poor due to lack of susceptibility, severity, barriers and self-efficacy perception
