[Trends in social inequalities in health in Catalonia, Spain].

The aim of this work is to analyze the evolution of social class inequalities in men and women in health status, health related behaviours and utilization of health services in Catalonia between 1994 and 2006. This is a study of trends based on the analysis of the Encuesta de Salud de Cataluña. To examine the association between 12 dependent variables and social class in each survey, robust Poisson regression models were fitted. People belonging to manual class showed the worst indicators. Over the period, social class inequalities in health status and health services utilisation tended to remain constant or to decrease (performing breast cancer screening). Conversely, inequalities in smoking increased. In Catalonia there are social class inequalities in health, among men and women, that tend to remain stable over the years.
