Table 2 Longitudinal effects, i.e. main effects and interaction effects with age, of the moveability index and its components (high: z-score ≥ 0 vs. low: z-score < 0) on moderate-to-vigorous physical activity (MVPA) and light physical activity (LPA) for N = 3394 Observations of n = 2488 3- to 15-year old children and adolescents stratified by sex

  1. Linear mixed models were adjusted for maximum ISCED level of both parents, parental safety concerns, sportsclub membership, valid wear time and season of accelerometer measurements, as well as study region; effect estimates not reported
  2. Bold significance is provided via confidence limits (significant if 0 is not included) which is similar to p-value
