Factors associated with smoking status (multinomial logistic regression).

	Former smokers OR (95% CI)	Current smokers OR (95% CI)
Age	0.98 (0.97–0.99)**	0.96 (0.95–0.98)###
Overweight/obesity	0.97 (0.72–1.31)	0.67 (0.48–0.94)#
Abdominal obesity	1.05 (0.75–1.48)	0.97 (0.67–1.40)
IGR	1.01 (0.80–1.27)	0.99 (0.75–1.33)
Hypertension	1.26 (1.03–1.56)*	1.15 (0.89–1.47)
Hypercholesterolaemia	1.26 (0.95–1.69)	1.40 (1.01–1.96)#
Hypertriglyceridaemia	1.10 (0.84–1.44)	1.14 (0.82–1.59)
Low HDL-C	0.97 (0.74–1.26)	1.39 (1.01–1.91)#
High LDL-C	0.81 (0.58–1.12)	1.07 (0.72–1.58)
CKD	1.23 (0.87–1.74)	0.96 (0.59–1.55)
IVD	1.48 (1.18–1.86)***	1.07 (0.79–1.43)

The analysis was adjusted for covariates (sex, educational level, marital status, alcohol drinking, and sedentariness). ‘Non-smokers’ was considered the reference category.

^*P < 0.05

OR: odds ratio; CI: confidence interval; HDL: high-density lipoprotein; LDL: low-density lipoprotein; IGR: impaired glucose regulation; IVD: ischaemic vascular disease; CKD: chronic kidney disease.
