RESUMEN
PURPOSE: High density lipoprotein-cholesterol (HDL-C) is a strong predictor of cardiovascular risk. We investigated the distribution of HDL-C in a French general population according to age, sex, and the risk factors associated with low HDL-C values. METHODS: A group of 18,483 men and 22,047 women 16-79 years of age were investigated during a medical check-up. Relevant parameters were studied in three groups according to age and gender-specific percentile classes (≤5th [HDL5] median and >95th). Gender-specific logistic regression models selected variables associated with HDL5. RESULTS: Using the National Cholesterol Education Program Adult Treatment Panel III criteria (threshold: 40 mg/dL in men, 50 mg/dL in women) the prevalence of low HDL-C was 11.1% and 26.4% in men and women and it decreased with age. Mean HDL-C levels increased with age. HDL5 was positively associated with a sedentary lifestyle and deprivation (p < 0.00001) even after adjustment on alcohol consumption and smoking. Abdominal obesity, smoking, hypertriglyceridemia, hyperleucocytosis, and low alcohol consumption were associated with HDL5 for both genders. CONCLUSIONS: The prevalence of low HDL-C was similar to that observed in other Europeans but lower than in the United States. HDL5 was associated with cardiovascular risk factors, metabolic syndrome, and social deprivation. A prevention policy to increase HDL-C levels should focus on reducing smoking and abdominal obesity, particularly in deprived subjects.
