title: [Pain prevalence in patients with and without OSAHS subjected to a polysomnogram: A cross-sectional study].
abstract: OBJECTIVE
  Sleep disturbances apparently have a negative effect on pain or the appearance of pain itself. This suggests the need to determine whether there could be a relationship between obstructive sleep apnea-hypopnea syndrome (OSAHS) and this phenomenon. The objective of this study was to determine the pain prevalence in a population who underwent polysomnography.
  
  
  METHODS
  A cross-sectional study of patients who underwent polisomnography, pain prevalence was measured with Mcgill pain questionnaire.
  
  
  RESULTS
  Data was obtained from 259 patients, and it was found that 69% suffered pain, and there was a prevalence of 81% OSAHS. Those with OSAHS had a 70% pain prevalence, with 64% for those without OSAHS.
  
  
  CONCLUSIONS
  A high pain prevalence was found this population, possibly related to the characteristic of the population, how the information was gathered, and not controlling for other illnesses related with pain.
