Note. BMD, bone mineral density. BW, Birth weight. BHC, Birth Head Circumference. CBMI, Childhood body mass index. 10F + 12M, the take-off phase of the growth spurt height standard deviation score SDS at 10 years in girls and 12 years in boys. PGF + PGM, the overall contribution of growth across puberty to adult height change SDS between 8 years and adult. PTF + PTM, the timing of peak height velocity by looking at the height change SDS between age 14 years and adult. TS, Tanner stage. The genetic correlation coefficients with p values < 0.05 were included in this table.
