Disease burden and mental health system capacity: WHO Atlas study of 117 low- and middle-income countries

Abstract

BackgroundTreatment coverage for mental disorders ranges from less than 10% to more than 90% across low- and middle-income (LAMI) countries. Studies have yet to examine whether the capacity of mental health systems might be adversely affected by the burdens of unrelated conditions such as HIV/AIDS.AimsTo examine whether the magnitude of disease burden from communicable, perinatal, maternal and nutritional conditions - commonly referred to as Group 1 diseases - is inversely associated with mental health system capacity in LAMI countries.MethodMultiple regression analyses were undertaken using data from 117 LAMI countries included in the 2011 World Health Organization (WHO) Mental Health Atlas. Capacity was defined in terms of human resources and infrastructure. Regressions controlled for effects of political stability, government health expenditures, income inequality and neuropsychiatric disease burden.ResultsHigher Group 1 disease burden was associated with fewer psychiatrists, psychologists and nurses in the mental health sector, as well as reduced numbers of out-patient facilities and psychiatric beds in mental hospitals and general hospitals (t= −2.06 to −7.68, P < 0.05).ConclusionsEvidence suggests that mental health system capacity in LAMI countries may be adversely affected by the magnitude of their Group 1 disease burden.
