Socioeconomic status and the prevalence of coronary heart disease risk factors.
South Asian countries have a high prevalence of coronary heart disease (CHD) in line with their economic development. India, in particular, has a high burden of CHD. Hence, the aim of the present study was to assess the prevalence of CHD risk factors in a semiurban population of Andhra Pradesh, India, in different socioeconomic status (SES) groups. Information was collected on socioeconomic status, physical activity, cigarette smoking, body mass, blood pressure (BP) and serum lipid profiles among a healthy sample of 440 men and 210 women with an age range of 20-70 years. Mean levels of serum cholesterol (SC), high density lipoprotein cholesterol (HDLC), low density lipoprotein cholesterol (LDLC) and skinfold ratio were found to be higher among women, whereas triglycerides (TG), systolic BP and diastolic BP were higher in men. No statistically significant differences in body mass index (BMI) or pulse rate were observed between the sexes. In men, a significant positive rank correlation (rho = P < 0.05) was observed between SES and SC, TG, systolic and diastolic BP, pulse rate and BMI, but in women, the same trend was found only with SC, TG, skinfold ratio and age. The prevalence (age standardized to the world population of Segi, 95% CI) of obesity was 14.37% (11.06-17.68), hypertension 13.13% (9.11-17.15), hypercholesterolemia 18.56% (13.88-23.24), hypertriglyceridemia 45.98% (36.47-55.49) and low HDLC 31.01% (24.25-37.77). In both sexes, the prevalence of hypercholesterolemia, hypertriglyceridemia and sedentary life style increased among higher SES groups (P < 0.05). Also, an increase in the level of social class was positively associated with mean levels of serum cholesterol and triglycerides in both men and women. The results demonstrate that higher SES groups have greater prevalence of CHD risk factors than lower SES groups. Preventive measures are required to reduce the risk factors among higher SES groups.
