Analyses adjusted for age, sex, pubertal status and household socioeconomic position.

MVPA = moderate-to-vigorous physical activity; R = Geometric mean of remaining activities. HRQL = health-related quality of life. Adiposity is a composite of body mass index z-score, waist girth z-score and percentage body fat; HRQL is estimated as the PedsQL Total Scale Score; Academic achievement is the mean of Grade 7 numeracy and literary (mean of reading, writing, spelling, and grammar and punctuation NAPLAN scores).
