Obesity tied to risk of psychiatric disorders

Obesity is a well known risk factor for certain physical health problems, but a new study suggests that heavy adults also have higher rates of psychiatric disorders.

Using data from a national health survey of more than 40,000 Americans, researchers found that obese adults were up to twice as likely to suffer from depression, anxiety and other mental health conditions as normal-weight adults.

In addition, even moderately overweight people had elevated rates of anxiety disorders, the study found.
