The aim of this study is to measure the prevalence of cardiovascular risk factors in Tavazzano (Lodi) inhabitants, in order to implement efficacious and preventive strategies at community level. In 1998 the target population consisted of 2055 adults (males and females) aged 35-64, living in Tavazzano (Lodi province). The examined population was made of 856 subjects (399 males and 457 females), with a participation rate equal to 41,6%. A questionnaire concerning medical history and life habits such as: smoking, alcohol consumption and physical activity was administered to each participant. Height, Weight, Systolic and Diastolic Blood Pressure, Fasting Blood Glucose, Total Cholesterol and triglycerides were collected. A 12-leads electrocardiogram, evaluated both with standard clinical criteria and Minnesota Code, was done for each subject. The results show a high prevalence of modifiable cardiovascular risk factors: hypertension (25,2%), smoking (26,1%), obesity (14,6%), hypercholesterolemia (27,5%), low physical activity (39,6%) mainly in males and with an increasing trend with age. These data indicate the need of preventive programmes addressed to the general population and to "subjects at risk", according to the National Health Plan 2003-2005.
