People suffering from depression or anxiety are more prone to be obese and to smoke, according to a study published in the journal General Hospital Psychiatry. The study, which compiled data from more than 200,000 adults, showed that those with current depression or a previous diagnosis of depression were 60% more likely to be obese and twice as likely to smoke as those who were not depressed. The research also found that people with an anxiety disorder were 30% more likely to be obese and twice as likely to smoke as those without anxiety.
