Background.: Recent studies promisingly indicate that adiponectin plays an important and fundamental role in the development and progression of metabolic and atherosclerosis disorders. Smoking is known as one of the most important risk factors of atherosclerosis, and its relation with metabolic disorders has also been reported. We therefore investigated the association between cigarette smoking and adiponectin concentration in a large sample of Japanese men and women. Method.: The cross-sectional study was carried out in 2002. The subjects were 3260 men and 953 women local government workers aged 35 to 59 in Japan. Lifestyle-related variables including detailed smoking history were inquired in a self-administered questionnaire. Results.: Significant differences in adiponectin levels related to smoking status were observed in both men and women (p = 0.001). A dose-dependent association was found between the intensity of smoking and adiponectin levels in current smokers, and was statistically significant in men (p for trend = 0.006 in the multivariate-adjusted model). Men who quit smoking for more than 20 years and women for more than 10 years had an adiponectin concentration similar to that observed in non-smokers. Conclusion.: We not only revealed that current smoking habit was associated with low adiponectin level but also found a dose-dependent association between smoking intensity and adiponectin level in current smokers. The present finding may provide further evidence of the importance of a causal relationship between smoking status and adiponectin concentrations.
