Waist size signals diabetes risk

Having a large waist is an important early warning sign for diabetes, one that in some cases may be just as significant as body mass index (BMI), if not more so, a new study has found.

Waist size, which provides a rough measure of a person's body type, may be especially useful for identifying high-risk people who are overweight but not obese, the study suggests. Obesity is a clear-cut risk factor for diabetes, but doctors generally have a harder time determining which overweight people are most vulnerable to the condition.

"Waist circumference is very helpful in people who are obese, but exceptionally helpful in people who are overweight," says Dr. Abraham Thomas, M.D., head of endocrinology and diabetes at Henry Ford Hospital, in Detroit. Thomas was not involved in the study.

Phone therapy helps with depression, study says

Receiving psychotherapy over the phone is showing promise for people with depression, according to new research. A study published Tuesday found patients counseled over the phone were less likely to drop out of treatment compared to those who got face-to face counseling.  Researchers also found people who talked to their therapist on the phone got better at the same rate as those who spent time on the counselor's couch.

"This research gives us a pretty clear indication that providing therapy via technology can be a useful strategy," says Lynn Bufka, assistant executive director, practice research and policy at the American Psychological Association.

Researchers at Northwestern University in Chicago conducted the study which was the first large trial comparing face-to-face therapy with telephone therapy. Their findings were published in the Journal of the American Medical Association.

Americans' heads have been growing, scientists say

If you're American with an average-sized head, your noggin is likely bigger than your ancestor's was seven generations ago.

That's the implication of research by Richard Jantz and colleagues at the Forensic Anthropology Center at the University of Tennessee.

The scientists analyzed about 1,500 skulls, dated from various years in the 1800s and 1900s. The researchers focused on Caucasian individuals because there weren't as many skulls from blacks and Hispanics. Although their conclusions are about white Americans, there is no reason to believe these patterns don't pertain to other races, Jantz said. More research just needs to be done.

Chronic sun exposure damages trucker's skin through glass

The striking photograph of a 69 year old truck driver in a recent New England Journal of Medicine article shows just how damaging the sun can be to your skin.

While driving a delivery truck for the last 28 years, the driver was exposed to ultraviolet A rays through the window glass on just the left side of his face. The rays penetrated the epidermis and the dermis, the first and second layers of the skin, causing a condition called unilateral dermatoheliosis.

Dermatoheliosis, also called photoaging, refers to changes in your skin due to chronic exposure to UVA and UVB rays. The result is a gradual thickening and deep wrinkling of the skin.
