β values are standardized regression coefficients. Analyses were adjusted for sex, peak height velocity (year) and parent education university level (neither/one/both). Statistically significant values are shown in bold (P < 0.05)
FA Fractional anisotropy, MD mean diffusivity, RD Radial diffusivity, AD Axial diffusivity, Ref. reference
*Statistically significant values surpassed multiple comparisons using the Benjamini and Hochberg method
†Combined physically active patterns were calculated as the sum of performing active commuting to school and physical activity before school
‡Combined non-physically active patterns were calculated as the sum of having breakfast and good sleep
