  1. BMI, body mass index; FM%, fat mass percentage; VAT, visceral adipose tissue; B, unstandardized beta; CI, confidence interval; AvAcc, average acceleration; IG, intensity gradient; MX metrics (M2, M5, M15, M30, M60, M120, and M1/3Day), the acceleration above which the most active 2, 5, 15, 30, 60, and 120 min, and 8 h are accumulated, respectively
  2. Analyses were adjusted for sex, maternal education level, maternal overweight and obesity, and wear time. The model with average acceleration was in addition adjusted for intensity gradient and vice versa. Boldfaced values: p < 0.05
