New Study Connects Aging and DHEA Levels in Men
New Study Reveals Compelling News about the Importance of DHEA
For years, researchers have examined the link between dehydropiandrosterone (DHEA) and aging. And up until now, the evidence has been inconclusive. But a new study published in the Journal of the American Geriatric Society may indicate something new.
Conducted in southwestern Japan over a 27-year period, the Tanushimaru Study, as it’s commonly known, analyzed the link between longevity and levels of blood serum dehydropiandrosterone sulfate (DHEAS), the sulfated form of DHEA. The largest and longest study of its kind to date, it tracked 940 subjects, aged 21 to 88, beginning with a baseline study in 1978. The participants received a complete physical exam, which included a measure of their serum DHEAS levels. Researchers continued to follow these subjects until the end of 2005.
Even after adjusting for factors like age, blood pressure and glucose levels, the study found a strong correlation between DHEAS levels and mortality risk in men. Men who began the study with less than 129 mcg/dL of DHEAS had about a 25% death rate, while the men whose DHEAS levels were over 200 mcg/dL had a death rate of less than 9%.
So if there is a link between DHEAS levels and longevity in men, why was the Tanushimaru Study the first such study to discover it? The researchers found that the benefits of higher DHEAS levels weren’t apparent until 15 years after the baseline study. And since all the previous studies were shorter than this, that may explain why the Tanushimaru Study was the first study to find this link.
