Hip bones keep growing wider as adults age

May 27, 2011

A new study finds people continue to grow well into their 70s, but they are growing wider, not taller.

Scientists discovered that people's pelvic bones continue to grow long after they reach skeletal maturity.

The end result is extra inches at the waistline and many extra pounds on the scale.

Authors of the study in the Journal of Orthopedic Research say pelvic width was about one inch larger around age 70, and that increase alone could amount to three extra inches on the waist between the ages of 20 and 79 years. Authors add that this widening could also account for a significant portion of an annual one-pound weight gain.
