The anabolic hormones testosterone, IGF-1 and DHEA (a pre-hormone) are receiving more and more attention by health professionals because the anabolic-catabolic imbalance that favors catabolism is a key factor in accelerated physical deterioration aging.[1, 2] Anabolic impairment can speed up the age-related decline in muscle mass and physical performance, increase in fat mass, development of insulin resistance, cardiovascular risk factors, metabolic syndrome and diabetes, conditions that in turn affect mortality.[3-18]
Interestingly, low levels of multiple anabolic hormones, rather than a single one, has a stronger association with age related muscle loss and the frailty syndrome. [19, 20] In men with chronic heart failure, deficiency of more than one anabolic hormone identifies patients with higher mortality rates.
An interesting study sought to investigate the relationship between parallel deficiency of several anabolic hormones and mortality in a general population of older men, regardless of coexisting disease:
