Data are presented as OR and 95 % CI.
1Irregularity score: higher score indicates higher irregularity in energy intake.
Model 1: Adjusted for age, gender and energy intake.
Model 2: Additionally, adjusted for marital status, education, disease history (diabetes, hypertension and hyperlipidaemia) and occupation.
Model 3: Additional adjustment for physical activity and smoking.
Model 4: Additional adjustment for BMI.
*Obtained from ordinal logistic regression model.
