Abstract:

   Background & Objective: Cardiovascular disease (CVD) is the main cause of morbidity and mortality in most countries. By identifying the population attributable risk (PAR) of the main risk factors of CVDs, the overall effect of various exposures on a population can be determined; the findings could be used in CVD prevention. The present study aimed to explore the PAR of some factors, including physical exercise, hypertension, obesity, high cholesterol level, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglyceride (TG), cigarette, hookah smoking, and drug and alcohol abuse, for CVDs.  Materials & Methods: This study was done in Yazd Province, Iran. The PAR of the above-mentioned factors were assessed. The used data were obtained from the first stage of the Shahedieh Cohort Study, conducted on over 10 000 residents (aged 35-70 years) of Shahedieh and annexed cities. PAR and the related Bayesian credible interval were calculated using R 3.4.3 software.  Results: Of 9967 studied subjects, 7.95% had CVD. The most usual risk factors for CVDs were inadequate physical exercise and abdominal obesity (waist-to-hip ratio [WHR]). Age was the strongest determinant of CVD. PAR for inadequate physical exercise was 25.48% in women and 14.14 % in men; WHR PAR was 46.93% in women and 31.42 in men.  Conclusion: Age cannot be controlled, so that CVDs are mainly attributed to high blood pressure. Therefore, blood pressure control should be considered as a primary strategy to reduce CVD incidence.

Attributable Fractions of Risk Factors for Cardiovascular Diseases

BACKGROUND Cardiovascular disease (CVD) is a leading cause of death in Japan. To reduce the threat of CVD, it is important to identify its major risk factors. The population attributable fraction (PAF) is calculated from the prevalence and relative risk of risk factors and can be used to estimate the burden of these factors with respect to CVD. We analyzed the findings from several prospective ...

Population Attributable Fraction for Cardiovascular Diseases Risk Factors in Selected Countries: A comparative study

BACKGROUND Cardiovascular diseases are the most common cause of death. The prevalence of cardiovascular diseases was reported to be 3,500 per 100,000. And it is predicted that these numbers will increase in the near future. By removing the main factors responsible for non-communicable diseases, cardiovascular disease can be prevented by 80%. AIM The aim of this study was to compare the popula...
