Education level and coronary risk factors in Australians.

Abstract

There is an inverse association between social class ranking and mortality from coronary heart disease in Australia and in some other countries. To explain whether this association is related to differences in risk factors, the relationship between coronary risk factors and the highest level of education completed was explored for a reasonably representative cross-section of the adult Australian population. After adjustment for the effects of age, relative weight and alcohol intake, blood pressure was found to vary inversely with education level in both sexes. In men only plasma cholesterol, triglycerides and high density lipoprotein cholesterol levels showed no significant variation with education level. In women, plasma triglycerides and high density lipoprotein cholesterol levels varied inversely with education level after adjustment. There was less cigarette smoking among more highly educated men but no clear smoking trends among women. The findings broadly confirm the results of similar analyses which used occupation as the measure of social class and have implications for future community education programmes in that present strategies may be inappropriate for less highly-educated members of society.
