Greene G, Gartner A, Farewell D, et al. - A longitudinal record-linkage study using a multistate model was designed to evaluate whether the direction of movement along the social gradient was correlated with changes in mental health status in Caerphilly, Wales, the UK between 2001 and 2015. The study population consisted of 10,892 (60.8% female) individuals aged 18–74 years. Researchers evaluated mental health in 2001 and 2008 using the Mental Health Inventory subscale of the short-form 36 V.2. Mental health selection was displayed in how individuals with common mental health disorders were less likely to shift to areas of lower deprivation but more likely to go to areas of greater deprivation. Poor mental health appears to encourage health selection in a similar way to poor physical health. Hence, funding targeted at areas of higher deprivation should recognize the requirement to be potentially higher as individuals with poor mental health may migrate into that area.
