Cigarette smoking and its association with serum lipid/lipoprotein among Chinese nonagenarians/centenarians

Abstract

Objective. Cigarette smoking had been confirmed as an increased risk for dyslipidemia, but none of the evidence was from long-lived population. In present study, we detected relationship between cigarette smoking habits and serum lipid/lipoprotein (serum Triglyceride (TG), Total cholesterol (TC), Low-density lipoprotein (LDL) and high-density lipoprotein (HDL)) among Chinese Nonagenarians/Centenarian. Methods. The present study analyzed data from the survey that was conducted on all residents aged 90years or more in a district, there were 2,311,709 inhabitants in 2005. Unpaired Students t test, 2 test, and multiple logistic regression were used to analyze datas. Results: The individuals included in the statistical analysis were 216 men and 445 women. Current smokers had lower level of TC (4.050.81 vs. 4.210.87, t=2.403, P=0.017) and lower prevalence of hypercholesteremia (9.62% vs. 15.13%, 2=3.018,P=0.049) than nonsmokers. Unadjusted and adjusted multiple logistic regressions showed that cigarette smoking was not associated with risk for abnormal serum lipid/lipoprotein. Conclusions: In summary, we found that among Chinese nonagenarians/centenarians, cigarette smoking habits were not associated with increased risk for dyslipidemia, which was different from the association of smoking habits with dyslipidemia in general population. © 2012 Yan-Ling et al.; licensee BioMed Central Ltd.
