Lifestyle and distribution of cardiovascular disease risk factors in an employee population

Lifestyle and dietary differences in smokers and non-smokers from an Italian employee population

In a sample of 200 subjects, representative of a population of 1936 civil servants, we tested differences in life style, dietary habits and distribution of risk factors for CHD between smokers and nonsmokers. The two groups (79 smokers) and (121 non-smokers) did not differ significantly by age or sex. The percentage of sedentary subjects, of hypercholesterolaemics and of hypertensives was found to be particularly high among smokers: 67%, 33% and 30% respectively (vs 59%, 27% and 19% in non-smokers). More smokers were obese (11% vs 5%) but mean BMI was the same in smokers/non-smokers but showed a higher fat mass; the association of CHD risk factors indicates only one significant correlation (P < 0.05) between obesity and hypertension. In male smokers, higher values of LDL and triglycerides and lower intake of energy, vitamins C and A are observed and these values are significantly different than those for non-smokers. In women HDL values are higher in non-smokers whereas, in female smokers, the food cholesterol intake is particularly high 271 +/- 295 mg. There are also correlations both for the anthropometric and clinical parameters and for energy and nutrients, indicating that the lifestyle of smokers is less healthy than that of non-smokers. Smokers cat vegetables and fruits less frequently and consume more alcohol than non-smokers, who prefer sweet foods.
