Balkrishnan and colleagues collected data from the National Ambulatory Medical Care Survey, which tracks Americans annual outpatient medical visits. The researchers identified 5,487 physician visits by patients with insomnia between 1995 and 2004, which was calculated to represent about 161 million U.S. patients over that 10-year period.

Of the visits examined, 38 percent of patients with insomnia were diagnosed with at least one other condition, and at least four of every 10 of those accompanying conditions related to mental health. The most common additional condition was anxiety (15.6 percent), followed by episodic mood disorders (14.9 percent), high blood pressure (10.1 percent), depression (7 percent) and diabetes (3.5 percent).

Those with anxiety were the least likely to receive a sleep aid, with a 45 percent decreased likelihood of receiving medication for insomnia compared to patients without anxiety.
