title: Intake of antioxidants in patients with rheumatoid arthritis.
abstract: OBJECTIVE
  to investigate dietary intake of antioxidants in patients with rheumatoid arthritis.
  
  
  METHODS
  this is a cross-sectional case series study with 53 women accompanied at the Rheumatology Outpatient Clinic, Hospital das Clínicas/UFPE, from January to October 2012. Demographic and anthropometric parameters (weight, height, body mass index, weight change) were collected by means of a form. The assessment of food consumption was conducted using a semi-quantitative food frequency survey, analyzed according to a food composition table. Database construction and statistical analysis were performed using Excel and SPSS version 18.0, using chi-squared test, Anova, and Student's t-test, at a confidence level of 5%.
  
  
  RESULTS
  the sample was composed of 53 women with a mean age of 54.51 ± 4.24 years and BMI of 25.97 ± 5.94 kg/m². In the sociodemographic variables, statistically significant differences in origin, occupation, and income were observed. Daily consumption showed significance for vitamins A, C, and zinc. In adults, vitamins A and C were in accordance with recommendations, while in the elderly a low intake of vitamin E and selenium was observed. The relation between vitamin E and origin was significant.
