BACKGROUND: Cardiovascular diseases (CVD) are the second leading cause of death, after accidents, in Iran. This study was performed to assess the change in levels of knowledge about 8 risk factors of CVD and its associated determinants the Iranian general population.METHODS: The current repeated cross-sectional study included 3014 people in 2004, 3012 in 2005, and 4719 in 2007, aged older than 19 years. Knowledge about 8 risk factors (high blood pressure, nutrition, physical inactivity, smoking, diabetes, heredity, stress, and obesity) as the major causes of CVD was evaluated using latent transition analysis (LTA).RESULTS: The most widely known CVD risk factors were nutrition and physical inactivity followed by stress. In addition, old age, low level of education, male gender and low socioeconomic status (SES) level were the significant determinants of low knowledge levels of CVD risk factors. Besides, individuals’ knowledge of CVD risk factors increased across the time.CONCLUSION: Public knowledge of CVD risk factors has increased; however significant gaps continue to exist, particularly among the elderly, less-educated people, people in low socioeconomic status level and men. Future intensified educational efforts by policymakers are necessary for improving knowledge of CVD, particularly among high-risk groups.
