Depression and anxiety were associated with respiratory disease in a cross-sectional prospective study of US adults.

Researchers gathered data from the Midlife Development in the United States survey, which provided a representative sample of US adults aged 18 to 74 years. Participants (n=2,101) were interviewed by telephone and mail on health issues during wave 1 (1994 to 1995) and then in wave 2 (2005 to 2006) to confirm the earlier findings.

Respiratory disease had a cross-sectional association with increased odds of depression and anxiety disorders during both periods.
