Significant results are highlighted in bold.

^aThe mean telomere length, relative to the reference DNA, was calculated and expressed as the mean T/S ratio.

^bLA is low adiposity, HA is high adiposity, LM is low muscle mass and HM is high muscle mass.

^cTrFM is truncal fat mass, ASM is appendicular skeletal mass.
