[Food habits and cardiovascular risk factors in 2 population samples of western Sicily].
Two population samples in western Sicily, one rural and one urban, were studied to evaluate the influence of dietary habits on cardiovascular risk factors. One hundred and fifty-five rural subjects (73 males, 82 females) and 155 age- and sex-matched urban subjects (71 males, 84 females) were enrolled. All subjects related their personal and familial history, physical activity levels, and had a complete physical and instrumental examination. Blood was collected after an overnight fast, without stasis. The following parameters were measured: blood glucose, total cholesterol, HDL-cholesterol, triglycerides, apolipoproteins A1 and B100, fibrinogen, factors VII and VIII, tissue plasminogen activator, plasminogen activator inhibitor, and plasminogen. Dietary habits were recorded on two occasions by means of a week diary (7-day food record). The rural sample followed the so-called "Mediterranean diet", while the urban sample followed a diet with significantly higher cholesterol and fat (in particular saturated fatty acids) intake and a significantly lower fiber intake. Both males and females in the rural population had significantly lower total cholesterol and apolipoprotein B100 levels than those in the urban sample, although rural males had significantly higher HDL-cholesterol levels. Both males and females in the rural sample had significantly lower factor VII and plasminogen activator inhibitor levels, although rural males had lower tissue plasminogen activator and fibrinogen levels than their urban counterparts. The positive effects of the "Mediterranean diet" on lipid, coagulation and fibrinolytic parameters which play a key role in the pathogenesis of atherosclerosis indicate that this dietary pattern should be adopted by the entire population.
