title: [Socio-economic inequalities and mental health. I. Concepts, theories, and interpretations].
abstract: OBJECTIVE
  Reconstructing the models used for approaching the inequalities issues in health, identifying the most relevant theoretical and conceptual contributions.
  
  
  METHODS
  Literature electronic-search on Medline, Psyclit, Econlit, Social Science Index and SocioSearch using the key-words inequalities, deprivation, poverty, socio-economic status, social class, occupational class, mental health for the period 1965-2002; integrated with manual search. The material was classified according to the conceptual and theoretical interpretative models or to the analyses of the association 'inequalities-health' where health was expressed as mortality, morbidity or services utilisation.
  
  
  RESULTS
  Four different interpretative models about the genesis of inequalities were identified. Further theoretical developments overcome the distinction among conceptuals contrapositions selection versus causation, statistic artefactual versus real differences, individual behaviours versus material context. Since the 80's the concept of material deprivation has been enlarged to include social deprivation to explain health inequalities. The social exclusion is related to material deprivation and to social fragility enlarging the traditional aspects of poverty. The theories that better adapt to the psychiatric field are the social selection and social causation.
  
  
  CONCLUSIONS
  The social exclusion and the new methodologies for measuring the inequalities seems to be an effective way for understanding of the inexplored aspects of the mental health inequalities.
