The objective of this study was to investigate the relationship between smoking history expressed by pack-years, metabolic and inflammatory markers, parameters of body composition (BC) and muscle strength among heavy smokers. A detailed smoking history was obtained from 49 heavy smokers (age ¼ 44 ± 12, pack-years ¼ 31 ± 23). Blood samples were analyzed for levels of glucose, lipids, liver enzymes and C-reactive protein (CRP). Anthropometric measurements included waist circumference and assessment of BC by dual energy X-ray absorptiometry (DEXA) and bioelectrical impedance analysis (BIA). Muscle strength was assessed by handgrip dynamometry and predicted one-repetition maximum (p1RM) tests. Positive correlations were found between pack-years of smoking, fasting glucose, alkaline phosphatase and CRP levels. Packyears were also positively correlated with waist circumference, body mass index (BMI), whole-body and trunk fat mass measured by both DEXA and BIA. A negative correlation was found between pack-years of smoking and muscle strength measured by p1RM for the leg press exercise. After adjustment for age, sex and BMI, a positive correlation remained between pack-years of smoking and CRP levels. In conclusion, after controlling for possible confounders, smoking history was found to be positively associated with CRP levels among heavy smokers.
