Abstract
Kuller, L H. (Dept. of Epidemiology, U. of Pittsburgh, Graduate School of Public Hearth, Pittsburgh, PA 15261), S. B. Hulley, R. E. La Porte, J. Neaton and W. S. Dai. Environmental determinants, liver function, and high density lipo-protein cholesterol levels. Am J Epidemiol 1983; 117: 406–18. High density lipoproteln cholesterol (HDL-chol) is negatively associated with coronary heart disease. Environmental heart disease risk factors may partially be related to coronary heart disease through alterations in HDL-chol concentrations. Little is known about the underlying mechanisms by which environmental factors are related to HDL-chol. The authors investigated a possible mechanism: changes in liver function as a mediating link between risk factors and HDL-chol concentrations in marathon runners, alcoholics, and participants in the Multiple Risk Factor intervention Trial. Liver function, as measured by liver enzymes, was related to both coronary heart disease risk factors and alcohol consumption, suggesting that the increased levels of HDL-chol associated with alcohol were primarily the result of changes in liver function. The relationship of obesity to HDL-chol could not be explained by the alterations in liver function.
