title: Socio-economic deprivation and the prevalence and prediction of depression in older community residents. The MRC-ALPHA Study.
abstract: BACKGROUND
  The Townsend index is a measure of social deprivation. It can be applied to postal districts and has been employed in studies examining the ecological associations of mental illness.
  
  
  OBJECTIVE
  We examine the utility of the Townsend index in identifying older populations with a high prevalence and risk of developing depression.
  
  
  METHODS
  The study was carried out in the context of a cohort study of an age- and gender-stratified sample of 5222 community residents aged 65 years and over. Subjects were interviewed at intervals of two years. The relationships between Townsend score and psychiatric diagnoses (in particular, depression) were examined.
  
  
  RESULTS
  High Townsend scores were associated with increased prevalence and incidence of depression and prevalence of organic psychiatric illness.
  
  
  CONCLUSIONS
  The Townsend index can be used to prioritize psychiatric and primary care resources so as to cater for older populations likely to suffer from depression and organic psychiatric conditions.
