*Obesity was defined as body mass index (BMI)>30 kilogrammes (kg) / square metres (m2), and severe obesity as BMI>40 kg / m2.
†Adjusted for gender (male or female), age (grouped in ten years), education level (high school or above), non-communicable disease (NCD) diagnosis (having hypertension, diabetes or dyslipidaemia), income (>200 Australian dollar (AU$) or not), and smoking. Frequent consumers are people with response as “almost daily” or “several times a week” for each food item.
‡Weighted for gender (male or female), age (grouped in ten years), education level (high school or above), NCD diagnosis (having hypertension, diabetes or dyslipidaemia), income (>200 AU$ or not), and smoking.
