"Smoking prevalence and its combination with some cardiovascular risk factors "

Abstract

This study was carried out on 2200 men and women aged 20-70 years in isfahan who participatd in isfahan Cardiovacular Risk Facor survery, in order to find prevalence of cigarette smoking in this population and estimate the relation of smoking with other CAD risk factors. All information was obtained by standard questionnaires mainly concerning smoking habits of subjects and their personal characteristics, etc. Serum lipids and fasting blood glucose levels were measured from 12-14 hr fasting specimen by ELAN 2000 autoanalyzer. Blood pressure was measured according to WHO standardized method. The prevalence of cigarette smoking among Isfanhan population is 11.1% (0.92 in women, 23.3%) in men. Contrary to serum total cholesterol (T.cho) and fasting blood sugar (FBS), the mean levels of HDL cholesterol (HDL-C) systolic (SBP) and diastolic blood pressure (DBP) and body mass index (BMI) were significantly higher in non-smokers than smokers (P<0.05). Hypertension and obesity were significantly more prevalent in non-smokers than smokers. When the prevalence of risk factors were studied in two BMI levels, the prevalence of hypertriglyceridemia was significantly more in smokers than non-smokers opposite to hypertension in either BMI level. Higher prevalence of low HDL-C and hypertension in either BMI level. Higher prevalence of low HDL-C and hypercholesterolemia was observed in smokdrs than non-smokers when BMI <27 kg/m2 was considered. The results of the present study revaled that hypertensions is more prevalent in non-smokers than smokers. The observation that high blood pressure was less common among smokers than non-smokers may be related to the lower prevalence of obesity in smokers.We conclude that due to the low prevalence of smoking in Iranian women, it is better to present the data regarding smoking as sex-based in our society. On the other hand Cigarette smoking is not only considered as a major risk factor for CVD but also it may have a role in increasing some of other CVD risk factors in our population
