Genes Influence Body Fat More Than Lean Mass
-
Genetic variants — single-nucleotide polymorphisms (SNPs) indicating susceptibility to having larger body size in childhood and other SNPs indicating susceptibility to having larger body size in adulthood — were associated more strongly with adiposity than with lean mass in a longitudinal study of English individuals who underwent surveillance six times during the period when they were 9 to 25 years old.

@michell Among girls and women, genetic variants for larger childhood body size were associated more strongly with adiposity than genetic variants for larger adult body size during childhood and adolescence. Among boys and men, genetic variants for larger childhood body size and genetic variants for larger adult body size showed similar degrees of association with adiposity during the first decades of life.
