Adipose tissue seems to be a pivotal organ in the aging process. We investigated whether healthy aging could have its roots in a sound metabolic condition from the first year of life by evaluating leptin and adiponectin levels in neonates [33 adequate for gestational age (AGA) and 29 small for gestational age (SGA)], 48 centenarians, and 50 healthy elderly subjects. At birth, SGA neonates showed lower leptin levels (SGA 0.88 +/- 0.28; AGA 2.22 +/- 0.91 ng/mL; p < 0.05) and comparable adiponectin levels with respect to AGA. At 1 year, SGA showed increased leptin (SGA 1.74 +/- 0.28; AGA 1.31 +/- 0.19 ng/mL) and slightly reduced adiponectin concentrations (SGA 35.51 +/- 2.53; AGA 38.56 +/- 3.18 microg/mL) than AGA. Centenarians showed lower leptin (centenarians 18.71 +/- 3.78; elderly 34.81 +/- 7.27 ng/mL; p < 0.05) and higher adiponectin levels (centenarians 55.63 +/- 7.7; elderly 33.51 +/- 4.1 microg/mL; p < 0.05) than elderly subjects. Centenarians, like AGA infants during the first year of life, show a favorable adipokine profile, suggesting that the metabolic condition at early age could affect the longevity of an individual.

Abstract
Adipose tissue seems to be a pivotal organ in the aging process. We investigated whether healthy aging could have its roots in a sound metabolic condition from the first year of life by evaluating leptin and adiponectin levels in neonates [33 adequate for gestational age (AGA) and 29 small for gestational age (SGA)], 48 centenarians, and 50 healthy elderly subjects. At birth, SGA neonates showed lower leptin levels (SGA 0.88 +/- 0.28; AGA 2.22 +/- 0.91 ng/mL; p < 0.05) and comparable adiponectin levels with respect to AGA. At 1 year, SGA showed increased leptin (SGA 1.74 +/- 0.28; AGA 1.31 +/- 0.19 ng/mL) and slightly reduced adiponectin concentrations (SGA 35.51 +/- 2.53; AGA 38.56 +/- 3.18 microg/mL) than AGA. Centenarians showed lower leptin (centenarians 18.71 +/- 3.78; elderly 34.81 +/- 7.27 ng/mL; p < 0.05) and higher adiponectin levels (centenarians 55.63 +/- 7.7; elderly 33.51 +/- 4.1 microg/mL; p < 0.05) than elderly subjects. Centenarians, like AGA infants during the first year of life, show a favorable adipokine profile, suggesting that the metabolic condition at early age could affect the longevity of an individual.Pubblicazioni consigliate
