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.[21]

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:[22]

Reduced levels of anabolic hormones can contribute to aging and frailty. Most studies that have investigated this focused on the relationship between individual hormones and specific age-associated diseases. An interesting study in older women aged 70-79 years sought to examine the associations of individual anabolic hormonal deficiencies of free testosterone, IGF-1 and DHEA, and to assess their combined effects as well.[1]
