Short height and long life have a direct connection in Japanese men, according to new research based on the Kuakini Honolulu Heart Program (HHP) and the Kuakini Honolulu-Asia Aging Study (HAAS).
“We split people into two groups – those who were 5-foot-2 and shorter, and 5-4 and taller,” said Dr. Bradley Willcox, one of the investigators for the study and a UH Mānoa Professor at the John A. Burns School of Medicine’s (JABSOM’s) Department of Geriatric Medicine. “The folks that were 5-2 and shorter lived the longest. The range was seen all the way across from being 5-foot tall to 6-foot tall. The taller you got, the shorter you lived.”
Researchers at the Kuakini Medical Center, JABSOM and U.S. Veterans Affairs worked on the study, which was recently published in PLOS ONE, a peer-reviewed medical journal.
The researchers showed that shorter men were more likely to have a protective form of the longevity gene, FOXO3, leading to smaller body size during early development and a longer lifespan. Shorter men were also more likely to have lower blood insulin levels and less cancer.
