title: The Effect of Exercise in PCOS Women Who Exercise Regularly.
abstract: OBJECTIVE
  To determine the prevalence of polycystic ovary syndrome (PCOS) in women who exercise regularly.
  
  
  METHODS
  All women under age 45 from an industrial company who had past history of exercising more than 6 months enrolled in this cross-sectional study. Prevalence of PCOS and comparison of BMI between PCOS and non-PCOS subgroups was done. The diagnosis of PCOS was based on the revised 2003 Rotterdam ESHRE/ASRM consensus criteria and exclusion of related disorders.
  
  
  RESULTS
  The prevalence of PCOS in was 8.8%; 95% CI: 8.5%-9.1%. In obese subjects, mean BMI differed significantly between PCOS and non-PCOS women (29.3 ±3.3 kg/m(2) vs. 27.8 ± 2 kg/m(2), P=0.03). In lean subjects, there was no statistically significant difference in terms of BMI between PCOS and non-PCOS women (21.4 ± 1.9 kg/m(2) vs. 21.2 ± 2 kg/m(2), P>0.05).
  
  
  CONCLUSIONS
  Obese PCOS patients show more difficulty in losing weight by exercise than lean PCOS patients. The role of hormonal alterations and PCOS per se in the responsiveness of weight loss to exercise remains to be determined.
