A study of 1,300 children between the ages of 11 and 17 in the U.S. has found that those who had asthma were nearly twice as likely to suffer from anxiety and depression. Previous studies have suggested a link between asthma and other mental-health problems such as panic disorder. After controlling for other variables children with asthma were found to be 1.9 times as likely to suffer from anxiety and depression. Children with asthma and a mental-health problem are more likely to smoke making it harder to treat their asthma. Girls and children living in a single-parent household were more likely to suffer from anxiety and depression as were those who had recently been diagnosed with asthma and those who had higher levels of physical impairment because of the condition.
