Change of poverty and outcome of persons with severe mental illness in rural China, 1994-2015.

Abstract

It is unknown whether and how poverty influences the long-term outcome of persons with severe mental illness (SMI). To explore the change of poverty status in persons with SMI from 1994 to 2015 and examine the impact of poverty status on patients' outcome in rural China. Two mental health surveys using identical methods and International Classification of Disease (ICD-10) were conducted in 1994 and 2015 in the same six townships of Xinjin County, Chengdu, China. The annual net income per person was 19.8% and 100.2% higher for the general population than for persons with SMI in 1994 and 2015 respectively. Compared with 1994 (48.2%), persons with SMI in 2015 had significantly higher rates of poor family economic status (<mean) (65.2%) (p < .001). Persons with SMI in poor family economic status were significantly more likely to be male, unmarried, unable to work, with no family caregivers or a smaller number of family members, and in poor mental status in 1994 and 2015 (p < .05). The risk factors significantly associated with patients' poor mental status included poor work ability, younger age of first onset, never-treated status and poor family economic status. Relative poverty of persons with SMI has become more severe during the rapid socioeconomic development in rural China. Relative poverty of household, poor work ability, younger age of onset and never-treated status are risk factors of poor outcome. Culture-specific, community-based interventions and targeted poverty alleviation programs should improve patients' early identification, treatment and recovery.
