^*Data presented as number and percentage.

^†Self-reported weight and height used to calculate BMI. BMI categories were defined as follows: healthy weight (BMI, 18·5–24·9 kg/m²), overweight (25–29·9 kg/m²) and obese (≥30 kg/m²); P-values for χ ² tests were calculated among age, gender, education, work status, income, specialisation and BMI.
