Notes: Variables are median and interquartile range except for height-for-age Z-score, body mass index-for-age Z-score, total weekly sedentary time, which are mean and standard deviation

n-values: Anthropometry: Control n = 79; AUDs n = 79; Physical activity and inactivity and Energy intake: n = 80 per group; males n = 33 and females n = 47

Height-for-age and body mass index-for-age expressed in Z-scores of the World Health Organisation Growth Reference for ages 5 to 19 years [20]

Smoking group includes light smokers (lifetime < 100 cigarettes) and regular smokers (lifetime > 100 cigarettes)

Multilevel mixed-effects linear regression used to compare groups, adjusting for gender, smoking status, physical activity (total weekly active time) and total estimated energy intake (including alcohol energy)

a Total weekly active time: sum of minutes per week spent doing regular (weekly) organised sporting activities

b Total weekly sedentary time: sum in minutes per week spent watching television and using a computer

c Energy intake, excluding estimated average daily alcohol energy

d Total estimated energy intake, including average daily alcohol energy estimated from average daily alcohol intake (grams) per participant in the alcohol use disorder group

* No significant differences between Control and AUD groups using χ2 or Fischer's exact test
