Distributions, mean values and correlations of various coronary risk factors in a population of Veneto]

During the National Research Council (CNR) program called Atherosclerosis-Risk Factors 2 (ATS-RF2) a random sample of 1903 subjects (50.1% male) aged 20-59 years was examined in the general population of Mirano-Venice. Mean values of serum total cholesterol and triglycerides, body mass index, as well as systolic and diastolic blood pressure were assessed. On the whole these turned out to be higher in men and increased with age. The continuously distributed variables showed an approximately normal distribution and a close correlation. Comparing our results with those obtained by other Italian units co-operating in the same CNR program, different levels of serum total cholesterol and systolic blood pressure were observed. The overall risk factor pattern in northern Italian regions is closer to that reported in the literature for central European countries than to that of southern Italian regions. These findings might explain why mortality due to ischaemic heart disease is higher in northern Italy and becomes progressively smaller in central and southern Italy.
