- Equity and the prevalence of chronic pain in PortugalPublication . Teixeira, Catarina de Oliveira; Gouveia, Miguel Rebordão de AlmeidaThe aim of this thesis is to estimate inequalities in chronic pain prevalence in Portugal, through data analysis of a representative stratified probabilistic sample of 18 204 valid answers from National Health Survey of 2014. To obtain accurate estimates design weights were applied in all the estimates below. Throughout this study it was possible to establish a relationship between chronic pain and socioeconomic status. For that, a logistic regression model was used, including sociodemographic characteristics and information concerning relevant chronic diseases. An analysis based on concentration curves and indexes was developed examining the association between chronic pain, income and education. After applying the methodologies mentioned above it was concluded that there are variables that do not contribute to explain chronic pain prevalence such as marital status, income, body mass index and heart attack or stroke incidence. As for significant variables, it was shown that age, gender, the education level, region and the prevalence of chronic diseases as bronchitis, urinary incontinence or renal failure could influence chronic pain prevalence. To improve the detail of the analysis, the sample was standardized for age and gender in order to develop concentration curves and indexes, based on the regression model stated before. It was possible to conclude that inequalities in chronic pain distribution are higher when education is taken into account, comparing with income level. It was also designed an income adjusted index concerning education level that revealed a trend for higher concentration of pain across groups with lower socioeconomic status.
