Prevalence of Mental Health Disorders in Adults

摘要

In developed countries, mental illnesses constitute a more sizable proportion of disability than other types of disease. They also can exacerbate the morbidity of coexisting disorders. Mental illness, therefore, is a significant public health problem that requires prompt and accurate identification. Prevalence: In 2009, U.S. adults experienced an average of 3.5 mentally unhealthy days during the previous 30 days. The mean number of mentally unhealthy days was highest in southeastern states. According to the CDC, 25% of adults have reported having a mental illness, and nearly half of adults will develop at least one mental illness during their lifetime.
