	Shift work patterns	Manual workers
		Crude OR (95% CI)	Model 1	Model 2
male	Day work	Reference	Reference	Reference
(n = 2094)	24-h shift	1.21 (0.49–3.02)	0.85 (0.31–2.37)	0.90 (0.31–2.63)
	Rotating 2 or 3 shifts	0.65 (0.22–1.93)	0.63 (0.17–2.33)	0.61 (0.17–2.22)

OR, odds ratio; CI, confidence interval. Model 1. Adjusted for age, body mass index, systolic blood pressure, fasting glucose, triglyceride, estimated glomerular filtration rate, history of hypertension, history of diabetes, smoking, alcohol. Model 2. Adjusted for age, body mass index, systolic blood pressure, fasting glucose, triglyceride, estimated glomerular filtration rate, history of hypertension, history of diabetes, smoking, alcohol, income, educational status, work hours for a week
