U.S. Adult Mental Illness Surveillance Report
Mental illness is an important public health problem in the United States. A new CDC report describes the extent of mental illness among U.S. adults and recommends increased efforts to monitor mental illness and anxiety disorders.
The economic burden of mental illness in the United States is substantial—about $300 billion in 2002. Mental illness is an important public health problem in itself—about 25% of U.S. adults have a mental illness—but also because it is associated with chronic medical diseases such as cardiovascular disease, diabetes, and obesity. Mental illness surveillance by organizations such as CDC is a critically important part of disease prevention and control.
The new CDC report, Mental Illness Surveillance Among Adults in the United States, describes the extent of mental illness among U.S. adults and recommends increased efforts to monitor mental illness and anxiety disorders. Released September 2, 2011, in CDC’s Morbidity and Mortality Weekly Report (MMWR), the publication is the result of CDC’s first agency-wide compilation of data from selected CDC surveillance and information systems that measure the prevalence and impact of mental illness in the U.S. adult population.
What is mental illness?
The term mental illness refers collectively to all diagnosable mental disorders. Effects of the illness include sustained abnormal alterations in thinking, mood, or behavior associated with distress and impaired functioning. The effects of mental illnesses include disruptions of daily function; incapacitating personal, social, and occupational impairment; and premature death. The most common mental illnesses in adults are anxiety and mood disorders.
How widespread is mental illness?
According to the World Health Organization, mental illness results in more disability in developed countries than any other group of illnesses, including cancer and heart disease. Other published studies report that about 25% of all U.S. adults have a mental illness and that nearly 50% of U.S. adults will develop at least one mental illness during their lifetime.
Where in the United States is the level of mental illness highest?
Depression estimates generally are highest in the Southeastern states (e.g., 13.7% in Mississippi and West Virginia vs. 4.3% in North Dakota).
What is mental illness surveillance?
Public health surveillance is the ongoing and systematic collection, analysis, interpretation, and dissemination of data used to develop public health interventions that reduce morbidity and mortality and improve health. Surveillance for a particular condition—such as mental illness—might depend either on collecting new data or using data obtained from existing health information systems.
Why is monitoring mental illness important?
Surveillance activities that monitor mental illness are essential because mental illness is a significant public health problem. For example,
according to the World Health Organization, mental illnesses account for more disability in developed countries than any other group of illnesses, including cancer and heart disease; published studies report that about 25% of all U.S. adults have a mental illness and that nearly 50% of U.S. adults will develop at least one mental illness during their lifetime; mental illness is associated with increased occurrence of chronic diseases such as cardiovascular disease, diabetes, obesity, asthma, epilepsy, and cancer; mental illness is associated with lower use of medical care, reduced adherence to treatment therapies for chronic diseases, and higher risks of adverse health outcomes; mental illness is associated with use of tobacco products and abuse of alcohol; rates for both intentional (e.g., homicide, suicide) and unintentional (e.g., motor vehicle) injuries are 2 to 6 times higher among people with a mental illness than in the population overall; population-based surveys and surveillance systems provide much of the evidence needed to guide effective mental health promotion, mental illness prevention, and treatment programs; monitoring mental illness is an important way to provide appropriate organizations the data they need to assess the need for mental and behavioral health services and to inform the provision of those services; many mental illnesses can be managed successfully, and increasing access to and use of mental health treatment services could substantially reduce the associated morbidity; many chronic illnesses are associated with mental illnesses, and it’s been shown that treatment of mental illnesses associated with chronic diseases can reduce the effects of both and support better outcomes; and CDC surveillance systems provide several types of mental health information, such as estimates of the prevalence of diagnosed mental illness from self-report or recorded diagnosis, estimates of the prevalence of symptoms associated with mental illness, and estimates of the effect of mental illness on health and well-being.
