Coronary heart disease risk factors in a random sample of Athenian adults. The Athens Study

Abstract

Risk factors for cardiovascular diseases not previously investigated in Greece were studied in a random sample of 4,097 Athenian adults. Mean systolic and diastolic blood pressures increased with age in both sexes. Similar findings were observed for mean serum total cholesterol up to age 50 years, but no significant changes were observed in older persons. Smoking was more common for men than for women and less common in those aged more than 50 years. Mean values of body mass index were higher for men than for women in those less than 45 years, but the opposite was observed for the older age groups. The age-adjusted prevalence rate of borderline hypertension was 10.1% for men and 9.1% for women and of stable hypertension (greater than 160/95 mmHg), 8.1% and 8.6%, respectively; the age-adjusted prevalence rate of obesity was 23.5% for men and 23.2% for women and of hypercholesterolemia (total cholesterol greater than or equal to 260 mg/100 ml), 20.1% for men and 17.3% for women. The associations of age and systolic blood pressure and of age and diastolic blood pressure persisted even after controlling for body mass index, total cholesterol, and smoking. In the examined representative sample, the prevalence rates of risk factors for cardiovascular diseases are the same or greater than those in industrialized countries.
