 Abstract
Introduction: Recent studies show that even small amount of smoking increases the risk of lung cancer and cardiovascular disease. However, the association between low-intensity smoking (ie, <1 or 1-10cigarettes per day(CPD)) and metabolic syndrome (MS) is not known.
Methods: 4,130 men over 18 years old were recruited from the Korea National Health and Nutrition Examination Survey, 2015-16 and divided into never smoker, former smoker, intermittent smoker(<1CPD), light smoker(1-10CPD), moderate smoker(11-20CPD) and heavy smoker(>20CPD) by smoking history. We tried to explore the association between current amount of smoking, duration of cigarette smoke, pack year and MS and its components. Logistic regression analysis was done to evaluate association between smoking status and MS with an adjustment for age, body mass index, house income, marital status, alcohol consumption, physical activity and comorbidity.
Results: In multivariate analysis, there are dose-response association with intensity of smoking and abdominal obesity, low-HDL cholesterol, high triglycerides, and MS (all p for trend<0.01), but not with high blood pressure and high fasting glucose. The amount of smoking that increased the risk was different for each component; significant from intermittent smoking (high triglycerides), light smoking (low-HDL cholesterol), moderate smoking (metabolic syndrome), and heavy smoking (abdominal obesity). Similar dose-response association between pack-year and MS was also present (p<0.001)
Conclusion: Smoking has dose-response association with MS, but inconsistent among its components. The risk of high triglycerides and low-HDL cholesterol may increase from even low-intensity of smoking, but the association of smoking with high blood pressure and glucose is not definite.
