Mental distress and functional health in the United States

- There are wide disparities in mental and functional health in the US.
- Variations are seen by location, race, employment and other demographic variables.
- Frequent mental depression increased from 2000 to 2014.
- Frequent mental depression had the highest rise from 2008 to 2013 due to economic adversity.
- Programs and policies to address MH at the state level are urgently needed.

IntroductionMental illness prevalence is increasing in USA. Understanding the relationship between functional status and mental health is crucial in optimizing psychiatric treatment.MethodsWe used 2000-2014 BRFSS data to examine the relationship between functional health and frequent mental distress in 51 states.ResultsEast-South-Central US (14.88%) had the highest prevalence of frequent mental distress and West-North-Central (9.42%) the lowest. Tennessee (15.7%) had the highest prevalence of frequent mental distress and North Dakota (7.4%) the lowest. East-South-Central had the highest prevalence on all functional limitation items. West Virginia had the highest prevalence of functional limitation (29.1%), use of special equipment (14.0%), blindness (8.6%), walking difficulty (23.0%), and difficulty running errands (12%). Females were more likely to report frequent mental distress in all states and more likely to report functional limitations in 32 states. Those who were divorced, smoker, unemployed, and of African American/American Indian/Alaskan native/other race were more likely to have a functional limitation. The prevalence of frequent mental distress increased steadily from 2000 for males and females but showed a decline from 2013 to 2014. The rate of increase was higher between 2008 and 2013 compared to previous years.ConclusionsOur study showed a high prevalence of mental distress and poor functional health in the US with a large variation between states and socio-demographic groups. Moreover, our findings showed a strong association between poor mental health and functional limitations. Our findings call for integrating mental and physical health research and clinical care to reduce the burden of mental health in the US.
