Adjusted hazard ratios (95% CI) for incidence diabetes according to baseline smoking status.

CI, confidence interval; BMI, body mass index.
1Difference in age-adjusted incidence rate per 1000 person-years between never smoker and current or former smoker.
2Adjusted for age (years), sex, and worksite.
3Adjusted for all factors in model 1 plus BMI (kg/m2), waist circumference (cm), and hypertension (yes or no).
4Adjusted for all factors in model 2 plus alcohol intake (<23 g ethanol/d or ≥ 23 g ethanol/d), shift work (yes or no), sleeping time (<6 h/d, 6–7 h/d, or ≥7 h/d), leisure-time physical activity (<150 min/wk or ≥150 min/wk), family history of diabetes (yes or no).
5Data were available for 32373 subjects.
6P for interaction for dichotomized variable of BMI (<23 or ≥23 kg/m2) on the association between smoking and type 2 diabetes was based on model 2 and was examined using the likelihood ratio test.
