Background Handling the growing epidemic of coronary heart disease in developing nations hinges on primary prevention, which logistically requires directing preventive interventions to those at the highest risk. Therefore, implementing cardiovascular risk assessment profiles is crucial to distinguish high risk groups who truly need extensive preventive measures. We aimed to draw a picture of the cardiovascular risk profiles in the Iranian adult population for the first time. Methods Demographic, anthropometric, and laboratory data as well as blood pressure and smoking status of 3944 subjects participating in the 2011 national surveillance of risk factors for non-communicable diseases were used to calculate the mean estimated risk of coronary artery disease and the relative frequency of low-, medium- and high-risk subjects based on FRS and SCORE indices in general population as well as different age, sex, and residence subgroups. Results The average 10-year risk of coronary artery disease (FRS) and 10-year risk of fatal coronary and cerebrovascular accidents (SCORE) in the 25 to 64 year-old population was 13.82 and 0.72 respectively. The relative frequency of the intermediate- and high- risk subjects was 25.8 and 22.6% based on FRS and 9.2 and 1.8% based on SCORE respectively. Average FRS and SCORE were significantly higher among men than women, but were not significantly different among urban and rural residents. Conclusions A significant proportion of the Iranian population, based on FRS model, will be at moderate to high risk of coronary events in the next 10 years. Urgent preventive plans are needed at the national level.

Background The burden of non-communicable diseases is rising globally. This trend seems to be faster in developing countries of the Middle East. In this study, we presented the latest prevalence rates of a number of important non-communicable diseases and their risk factors in the Iranian population. Methods The results of this study are extracted from the third national Surveillance of Risk Factors of Non-Communicable Diseases (SuRFNCD-2007), conducted in 2007. A total of 5,287 Iranian citizens, aged 15–64 years, were included in this survey. Interviewer-administered questionnaires were applied to collect the data of participants including the demographics, diet, physical activity, smoking, history of hypertension, and history of diabetes. Anthropometric characteristics were measured and serum biochemistry profiles were determined on venous blood samples. Diabetes (fasting plasma glucose ≥ 126 mg/dl), hypertension (systolic blood pressure ≥ 140 mmHg, diastolic blood pressure ≥ 90 mmHg, or use of anti-hypertensive drugs), dyslipidemia (hypertriglyceridemia: triglycerides ≥ 150 mg/dl, hypercholesterolemia: total cholesterol ≥ 200 mg/dl), obesity (body mass index ≥ 30 kg/m2), and central obesity (waist circumference ≥ 80 cm in females and ≥ 94 cm in males) were identified and the national prevalence rates were estimated. Results The prevalence of diabetes, hypertension, obesity, and central obesity was 8.7% (95%CI = 7.4–10.2%), 26.6% (95%CI = 24.4–28.9%), 22.3% (95%CI = 20.2–24.5%), and 53.6% (95%CI = 50.4–56.8%), respectively. The prevalence of hypertriglyceridemia and hypercholesterolemia was 36.4% (95%CI = 34.1–38.9%) and 42.9% (95%CI = 40.4–45.4%), respectively. All of the mentioned prevalence rates were higher among females (except hypertriglyceridemia) and urban residents. Conclusion We documented a strikingly high prevalence of a number of chronic non-communicable diseases and their risk factors among Iranian adults. Urgent preventive interventions should be implemented to combat the growing public health problems in Iran.
