Association of IGF-1 (Insulin-Like Growth Factor-1) with Mortality, Cardiovascular Disease, and Cancer

IGF-1 (insulin-like growth factor-1) is a peptide hormone, produced predominantly by the liver in response to pituitary GH (growth hormone).[1] IGF-1 is involved in a wide variety of physiological processes. In adults, IGF-1 has metabolic and anabolic effects, and it mediates many of the effects of GH.[2-4]
 
GH and IGF-1 levels are reduced with normal aging, a phenomenon called somatopause.[5-7] It has been suggested that somatopause is an age-related GH deficiency state.[5] Somatopause has been considered to contribute to physiological deterioration seen with aging, like reduced muscle mass, reduced exercise tolerance, decreased strength, osteoporosis, increased fat mass, elevated cardiovascular risk, impaired quality of life, cognitive/memory decline and reduced immunity.[7-12] These changes are similar to those seen in classic (non-aging related) GH deficiency (GHD).[13, 14]
