title: Prevalence of angina pectoris in the Brazilian population from the Rose questionnaire: analysis of the National Health Survey, 2013.
abstract: OBJECTIVE
  To estimate the prevalence of angina pectoris in the Brazilian adult population with the use of the Rose questionnaire for angina in the National Health Survey (PNS 2013).
  
  
  METHODS
  Population survey representing the Brazilian population aged 18 years and older, with probability carried out sampling in three stages. The interview records of 60,202 individuals were obtained in the country. The respondent was presented with the short Rose questionnaire with three questions, adapted by Lawlor in 2003 and validated in Brazil, to identify angina pectoris grade I (mild) and II (moderate/severe). The prevalence rate was calculated with a 95% confidence interval (95%CI) according to sex, age, education, and race/color.
  
  
  RESULTS
  The prevalence of mild angina (grade I) was of 7.6% (95%CI 7.2 - 8.0) for the entire population, more frequently in women - 9.1% (95%CI 8.5 - 9.7) - than in men - 5.9% (95%CI 5.3 - 6.4). The frequency of moderate/severe angina (grade II) was of 4.2 (95%CI 3.9 - 4.5), also more common in women - 5.2% (95%CI 4.7 - 5.6) - than in men - 3.0% (95%CI 2.7 - 3.4). The prevalence of angina by age group increased progressively with age. The prevalence of angina of any sort was inverse to years of formal study. Despite the higher value of the presence of angina in black people, there was no significant difference by race/skin color.
  
  
  CONCLUSIONS
  The high prevalence rate of angina pectoris in the population aged 18 years and above was consistent with studies in other countries, revealing the importance of coronary heart disease as a public health problem.
