title: EQ-5D-3L as a health measure of Brazilian adult population.
abstract: OBJECTIVE
  This study explores the use of EQ-5D-3L as a measure of population health status in a Brazilian region with significant socioeconomic, demographic, and epidemiological heterogeneity.
  
  
  METHODS
  Data came from a study of 3363 literate individuals aged between 18 and 64 years living in urban areas of the state of Minas Gerais. Descriptive analysis and logistic and OLS regression models were performed to analyze the relationship between EQ-5D-3L (descriptive system and EQ VAS) and other health (self-assessed health status and 8 self-reported diagnosed chronic diseases), socioeconomic (educational level and economic class), and demographic (gender and age) measures. Additionally, a grade of membership (GoM) analysis was performed to identify multidimensional health profiles.
  
  
  RESULTS
  A total of 76 health statuses were identified in the Brazilian population. The most prevalent one is full health (44 % of the sample). Elderly people, women, and individuals with poor health and lower socioeconomic conditions generally report more health problems in the EQ-5D-3L dimensions. The GoM analysis demonstrated that health status of older individuals is associated with the socioeconomic condition. Arthritis exhibited the strongest association with the EQ-5D-3L instrument.
  
  
  CONCLUSIONS
  The results indicate that EQ-5D-3L is a good measure of health status for the Brazilian population. The instrument has a good discriminatory capacity in terms of demographic, socioeconomic, and health measures. The high prevalence of individuals with full health may indicate the presence of ceiling effect. However, this prevalence is smaller than that in other countries.
