Association of total cholesterol, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol with atherosclerotic cardiovascular disease and cancer in a Chinese male population

Abstract

This prospective study included 68,759 Chinese male adults from Kailuan cohort of China who had a standardized medical examination between 2006 and 2007 and were followed up for approximately 8 years until occurrence of ASCVD, cancer or death or until December 31, 2014. Subjects were divided into four categories based on the quartiles of TC, LDL-C and non-HDL-C. Cox regression models were used to estimate hazard ratios (HRs) and their 95% confidence intervals (CIs). During follow-up, 2,916 males developed ASCVD and 1,884 developed cancer. Compared with the lowest quartile, the upper-most quartiles of TC, LDL-C and non-HDL-C were all associated with increased ASCVD risk (HR 1.53; HR 1.16; HR 1.55); however, the upper-most quartiles of TC, LDL-C and non-HDL-C were all negatively associated with cancer (HR0.84; HR 0.82; HR 0.80) and these associations were present after exclusion of incident cancers during the first 4 years of follow-up. In a word, we report that high TC, LDL-C and non-HDL-C concentrations increased ASCVD incidence in a male population and that these lipid profiles were inversely associated with total cancer and several individual cancers.
