AimSeveral studies have suggested that cigarette-smoking affects insulin sensitivity in Western populations. The present study evaluated glucose tolerance, pancreatic β-cell function and insulin sensitivity in relation to active and passive smoking among the Japanese.MethodsA total of 411 men and 586 women were recruited into a community-based cross-sectional study in Gifu, Japan. Diabetes, impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) were screened for by a 75 g oral glucose tolerance test. HOMA and insulinogenic (ΔI0−30/ΔG0−30) indexes were used to estimate insulin secretion and sensitivity. To assess the possible association of self-reported smoking status and parameters of glucose metabolism, logistic regression was applied after adjusting for potential confounders.ResultsCurrently smoking women were more likely to have diabetes, IGT or IFG compared with never-smoking women (OR: 2.26, 95% CI: 1.05–4.84). Heavy-smoking men (≥ 25 cigarettes/day) were likely to be in the lowest tertile group of ΔI0–30/ΔG0–30 compared with never-smoking men (OR: 2.64, 95% CI: 1.05–6.68, Ptrend = 0.04). The number of cigarettes/day was borderline significantly associated with diabetes in men. Also with borderline significance, never-smoking women with smoking husbands were more likely to have diabetes, IGT or IFG (OR: 1.62, 95% CI: 1.00–2.62) and significantly more likely to have lower HOMA-β (OR: 2.17, 95% CI: 1.36–3.48) than those without smoking husbands.ConclusionThe greater the number of cigarettes smoked per day appears to be associated with diabetes among men whereas, among women, both active and passive smoking appear to be associated with diabetic states, including IGT and IFG. An association between smoking status and insulin secretion is also suggested, whereas no significant association was observed with HOMA-IR in this Japanese subjects, suggesting that the influence of smoking on glucose metabolism may differ among races.
