ALT, alternative allele; BMI, body mass index; bp, base pair; Chr., chromosome; REF, reference allele; SE, standard error; SNP, single nucleotide polymorphism.
aPositions are based on Human Genome version 19 (hg19), build 37.
bAlternative alleles were treated as effect alleles.
cSignificant P-values (P ≤ 1.77E-04) are shown in bold.
dAdjusted model in current BMI were adjusted for age (continuous), age-squared (continuous), sex (male or female), birth year (continuous), and the first five principal components (continuous).
eAdjusted model in BMI at 20 were adjusted for sex (male or female), birth year (continuous), and the first five principal components (continuous).
fAdjusted model in BMI change were adjusted for age (continuous), age-squared (continuous), sex (male or female), birth year (continuous), the first five principal components (continuous), and BMI at 20 (continuous).
