title: The attitude of gynecologists in São Paulo, Brazil 3 years after the Women's Health Initiative study.
abstract: OBJECTIVE
  The objective of this study was to evaluate gynecologists' knowledge of the WHI study, and its repercussions on their attitudes and practice 3 years after publication.
  
  
  METHODS
  A self-administered, anonymous questionnaire containing 19 questions was sent to 6000 gynecologists, members of the São Paulo Society of Obstetrics and Gynecology.
  
  
  RESULTS
  The response rate was 24.2% (1453 completed questionnaires) with a sample error of 2.23% and confidence level of 95%. Although 95.9% of the respondents were aware of the WHI study, only 24.4% knew of all the other studies mentioned (HERS I, HERS II and Million Women Study). Although 84.6% stated that the results of the WHI study could not be extrapolated to other forms of HT, 23.1% and 25.2%, respectively, stopped prescribing CEE or MPA, 63.7% decreased the dose, 55.2% opted for drugs such as bisphosphonates, tibolone and SERMS, and 46.3% began to prescribe tranquilizers, isoflavone and other natural medications. Moreover, 59.2% agreed that HT should be used for only 4-5 years. Prescriptions decreased significantly for all indications (p<0.0001). The principal reason for physicians to discontinue HT in a patient was increased risk of breast cancer (62.3%), whereas, according to the physicians, the most important factor for the patients was fear of HT (80.3%).
  
  
  CONCLUSIONS
  A high percentage of gynecologists in this study knew of the WHI study and followed its recommendations concerning cardiovascular prevention; consequently they changed their management of the treatment of postmenopausal women by restricting indications for HT and decreasing its duration of use and dose.
