Purpose:The identification and control of risk factors is a crucial measure to be able to act appropriately and reduce the risk of cardiovascular disease (CVD).
e_COR is a national study that will be performed in the 5 Portuguese sub-regions. This study aims to contribute to produce scientific evidence for decision in public health, in particular to better define strategies in the area of cardiovascular prevention.
The aim of the present report was to estimate the prevalence of major CVD risk factors and to evaluate the perception, treatment and control of diabetes, hypercholesterolemia, hypertriglyceridemia, and hypertension, using the data collected in three sub-regions (Norte, Centro and Lisboa regions).
Methods: This study was conducted on a sample of 1027 individuals of both genders (522 men, 505 women), between 18 and 79 years. The data collected were obtained from a fasting venous blood sample, a physical examination and a clinical questionnaire. Statistical analysis was performed using the SPSS version 22.0.
Results: The estimated prevalence rates were as follows: inadequate diet (68.4%), overweight/obesity (64.9%), hypertension (50%), physical inactivity (34.4%), smoking (active smoking 22,2%, passive smoking 25,4%), alcohol abuse (21.0%), hypercholesterolemia (LDL-C> 160 mg/dl, 16.2%; LDL-C> 1115 mg/dl, 69.9%), family history of premature CVD (15%), diabetes (11.3%) and hypertriglyceridemia (>200 mg/dl, 7,5%; >150 mg/dL 19,3%). About 4% (42) of our population has LDL-C=P95 and from these 1,8% (18) have both LDL-C=P95 and family history of severe hypercholesterolaemia, fulfilling this way clinical criteria for familial hypercholesterolamia. Additionally 11.4% have HDL-C160mg/dl); 23.4%, 11.7% and 33% for hypertriglyceridemia (>200 mg/dl); and 64.4%, 74.3% and 39.5% for hypertension.
About 55.2% of our population already has 2 or more vascular risk factors, considering only the most important risk factors: diabetes, hypercholesterolemia, hypertension, overweight / obesity and smoking.
The remaining two regions, Algarve e Alentejo, are under evaluation
Conclusion: High rates for all CV risk factors were observed in our population but the major concern are the low rates of control of all risk factors, especially hypertension and diabetes. This is a serious public health problem that needs to de addressed by our local health policies.
