Effect of smoking on the blood lipid level of male patients with type 2 diabetes / 安徽医科大学学报

ABSTRACT

Objective To explore the effect of smoking on the triglyceride ( TG ) , cholesterol ( TC ) , high density lipoprotein-cholesterol(HDL-C) and low density lipoprotein-cholesterol(LDL-C) with the male type 2 diabetes. Methods Selected 144 male patients with type 2 diabetes, then divided them into four groups, including non-smokers, former smokers,current mild(≤20 per day) smokers and current heavy ( >20 per day) smokers. All of them were investigated about the age, diabetes pathogenesis, exercise, diet, smoking, lipid-lowering drugs used and checked with TG, TC, HDL-C, LDL-C and so on. The difference of TG, TC, HDL-C, LDL-C among these four groups was compared by the methods of covariance analysis, regression analysis and partial correlation to evalu-ate the relationships of smoking with blood lipid. Results TG of heavy smokers was higher than the non-smokers and HDL-C was lower after correcting the effects of other possibly relative factors(P<0. 05). HDL-C of the former smokers was higher than smokers and TG was lower than heavy smokers(P<0. 05). Smoking was an independent risk factor for HDL-C ( P<0. 05 ,β= -0. 213 ) , and there was a significantly negative relationship between daily cigarette consumption and HDL-C ( r= -0. 223 , P<0. 05 ) . Conclusion Smoking is an important risk factor for the diabetic male patients’ metabolism of the TG and HDL-C,independent of age, body mass index, blood pres-sure,exercise,diabetes pathogenesis, percentage of body fat and blood glucose. Smoking promotes the type 2 diabet-ics’ disorder of blood lipid and smoking cessation is of significance for the diabetics’ regulation of blood lipids.
