GORBATCHEV, Denis et al. Prevalence of dislipidemia in smokers from a Smoking-Cessation Clinic. Rev. Inst. Nal. Enf. Resp. Mex. [online]. 2006, vol.19, n.2, pp.102-107. ISSN 0187-7585.

Background: Tobacco smoking is one of the major modifiable cardiovascular risk factors. The relationship between smoking and lipid disorders has been studied; however, its prevalence among smokers from our Smoking Cessation Clinic (SCC) "Dra. Carmen Gutiérrez de Velasco " at the Instituto Nacional de Enfermedades Respiratorias Ismael Cosío Villegas is unknown. Objective: To describe the lipid profile of smokers at our SCC and its prevalence in this population. Methods: 700 medical records from patients admitted to the clinic during a three- year period from 2003 to 2005 were studied. We analyzed the prevalence of their atherogenic lipid profile defined as high serum total cholesterol and triglycerides and low HDL-cholesterol. In addition, we studied the prevalence of each component of the lipid profile, according to a gender and a number of cigarettes (cig) smoked per day. Results: The prevalence of atherogenic lipid profile, hypercholesterolemia, hypertriglyceridemia and low HDL-cholesterol was 21%, 50% 56% and 55%, respectively. Their total serum cholesterol and triglycerides levels were high and HDL-cholesterol was low (CT 204 ± 44 mg/dL, TG 208 ± 155 mg/dL, HDL 46 ± 14 mg/dL). Those who smoked more than 20 cig/day had higher triglycerides and lower HDL-cholesterol than those smoking less than 20 cig/day (225 ± 162 mg/dL vs 185 ± 134 mg/dL, p = 0.02 and 44.2 ± 12 mg/dL vs 48 ± 14 mg/dL, p<0.001, respectively). Women had higher HDL-cholesterol than men (51 ± 14 mg/dL vs 40.3 ± 11 mg/dL, p < 0.001). Conclusion: The high prevalence of an atherogenic lipid profile in smokers makes them prone to develop premature atherosclerosis. This study underscores the importance of lipid disorders research in smokers.
