Model 1: adjust for age, smoking and drinking status, fruit and vegetable, high-salt foods, high-fat foods, late evening snack, body mass index, sleep duration, physical activity, blood pressure, ECG, fasting plasma glucose, haemoglobin.
Model 2: based on model 1, adjust for importance of noise protection equipment, long working hours, dust, benzene series, shift work.
