Blood lipids in Italy. Regional differences

Serum cholesterol and triglyceride levels have been evaluated in samples from fasting males aged 20--59 in Northern (Brisighella), Central (Rome) and Southern (Pozzuoli) Italy. Regularly performed quality controls between laboratories assured comparability of data. A statisitically significant difference of mean serum cholesterol and triglyceride levels was observed for most age-groups in the 3 different areas, lower values being found in the southern population as compared to the central and northern ones. These results support previous findings and the thesis that large differences in blood lipid levels may still exist even within the same country and that they at least in part may be culturally determined in connection with different dietary habits.
