Just 'weight' until menopause
Date:3/27/2013

This press release is available in French.

Montreal, March 27, 2013 Women tend to carry excess fat in their hips and thighs, while men tend to carry it on their stomachs. But after menopause, things start to change: many women's fat storage patterns start to resemble those of men. This indicates that there's a link between estrogen and body fat storage. This connection is well documented, but the underlying mechanisms remained poorly understood until now.

New research conducted by Sylvia Santosa, assistant professor in Concordia University's Department of Exercise Science and Canada Research Chair in Clinical Nutrition, gives us a new look at the connection between fat storage and estrogen. By examining the fat storage process at a cellular level, Santosa and co-author Michael D. Jensen of the Mayo Clinic in Rochester, Minnesota, reveal that certain proteins and enzymes are more active in post-menopausal women. These proteins correspond with fat storage. Their findings were published in the March 2013 issue of Diabetes.

"The fat stored on our hips and thighs, is relatively harmless," explains Santosa, who is also a member of Concordia's PERFORM Centre for better health through prevention. "But the fat stored around the abdomen is more dangerous. It has been associated with diabetes, heart disease, stroke and even some cancers. When post-menopausal women put on more abdominal fat, they dramatically increase their risk for these health problems. Given these dangers, it is very important to understand the how the lower levels of estrogen associated with menopause changes where fat is stored."

Santosa's research compared fat storage in pre- and post-menopausal women. The 23 women who participated in the study were in the same age range, and had similar Body Mass Indices and body fat composition. These similarities allowed S
