A latest research claims that shorter men tend to live longer.
Researchers at the Kuakini Medical Center, the UH John A Burns School of Medicine and U.S. Veterans Affairs focused on the data gathered from the Kuakini Honolulu Heart Program (HHP) and the Kuakini Honolulu-Asia Aging Study. The Kuakini HHP was started in 1965 and involved 8,006 Japanese-American men that were born between 1900 and 1919. In general, the researchers counted that around 1,200 men lived into their 90s and 100s. Roughly 250 of them are still alive today.
The findings showed that shorter men who were of Japanese descent residing in Hawaii lived longer than taller men of the same origins.
"We split people into two groups - those that were 5-foot-2 and shorter, and 5-4 and taller," Dr Bradley Willcox, one of the investigators for the study and a professor in the University of Hawai'i (UH) John A. Burns School of Medicine's Department of Geriatric Medicine, said in a press release. "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."
According to the researchers, the association between height and life expectancy might be because of genes. They found that shorter men were more likely to have the FOXO3 gene that is known for a smaller body size and a longer life expectancy. The researchers found that the shorter men were also less likely to have cancer and more likely to have lower blood insulin levels.
"This study shows for the first time, that body size is linked to this gene," said Dr Willcox. "We knew that in animal models of aging. We did not know that in humans. We have the same or a slightly different version in mice, roundworms, flies, even yeast has a version of this gene, and it's important in longevity across all these species."
The study, 'Shorter Men Live Longer: Association of Height with Longevity and FOXO3Genotype in American Men of Japanese Ancestry,' was published in 'PLOS ONE.'
