Evolution of socioeconomic inequalities in smoking: results from the Portuguese national health interview surveys

摘要

BackgroundSouthern European countries were traditionally characterized by a higher prevalence of smoking among high socioeconomic groups. Though, recent studies show a reversal of inequalities in Italy and Spain, for example. We investigated whether this evolution also applied to Portugal by describing the evolution of socioeconomic inequalities in smoking between 1987 and 2006.
