  1. P-values <0.05 are in bold and signify a statistically significant difference
  2. Models were adjusted for age of child, maternal educational attainment and maternal nationality
  3. KINDL-Scores: Higher values indicate more quality of life
  4. SDQ-Scores: Higher values indicate more difficulties, except for SDQ-prosocial-score, where it is the inverse. Physical activity-score: Higher scores indicate more physical activity
