Study Says Shorter Men Live Longer

A new study suggests being short could actually make you live longer than your peers.

According to the research based on the Kuakini Honolulu Heart Program (HHP) and the Kuakini Honolulu-Asia Aging Study (HAAS), short height and long life have a direct connection in Japanese men.

"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 Hawaii (UH) John A. Burns School of Medicine's Department of Geriatric Medicine said.

"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," he said.

Researchers at the Kuakini Medical Center, the UH John A. Burns School of Medicine and U.S. Veterans Affairs worked on the study.

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.

"This study shows for the first time, that body size is linked to this gene," Dr. Willcox said.

The study is published in PLOS ONE, a peer-reviewed medical journal.

I have studied longevity and height for about 40 years and I have published in about 40 medical, nutritional, and scientific journals and books. My work has found a longevity advantage for shorter people. A number of biological mechanisms are at work to promote longevity for smaller people. These include: 1. Fewer cell replications allow a reserve of cells for use during old age. 2. Insulin and other growth factors are lower and low levels are related to greater longevity. 3. Smaller left ventricular mass of the heart is related to reduced heart failure and all-cause mortality. 4. Lower levels of C-reactive protein, homocysteine, and glucose reduce mortality. 5. Lower blood pressure. 6. Lower damage to DNA. 7. Lower free radical generation with reduced cell damage. 8. Higher sex hormone binding globulin [low levels have a variety of harmful effects.] The above assumes similar economic status, lifestyle, and body proportions. Height is about 10% of the longevity picture. Therefore, tall people can offset their tall height by improved nutrition, lower weight and lifestyle habits. However, I found that we lose about 1.3 years per inch of increased height. For more information on how our physiology, performance and impact on resources and the environment change with increasing body size, see www.humanbodysize. The book, The Truth About Your Height, provides information on height as well.
