- †from latent class analysis; *P ≤ 0.05, ***P ≤ 0.001 (all 2-sided); aphysical activity scores were derived from self-reported frequency and intensity of leisure-time physical activity and categorized as sedentary < 40 MET/minutes per week, low = 40- 600 MET/minutes per week, moderate = 600-1,200 MET/minutes per week, high >1,200 MET/minutes per week; bBMI = weight in kilograms/height in metres2 and categorised as underweight = BMI <18.5, healthy weight = BMI ≥18.5 - <25, overweight = BMI ≥25 - <30 and obese = BMI ≥30; crarely = drinks less than 1/week, low-risk ≤ 14 drinks/week, risky ≥ 15 drinks/week; S2 = asked at survey 2; all variables had ≤4% missing data except for physical activity (18.1%).
