title: [Prevalence of clinical and subclinical hypothyroidism during pregnancy in a pregnant women population].
abstract: OBJECTIVE
  To determine the prevalence of hypothyroidism during pregnancy in a group of pregnant patients attending antenatal care at the National Institute of Perinatology and to meet cases not detected by universal screening.
  
  
  METHODS
  Was conducted from October 2012 to March 2013, in a group of pregnant patients attending to National Institute of Perinatology, thyroid profile was performed according to the recom- mendations of the American Thyroid Association. Patients were referred to endocrinology consultation and treatment was started in case of abnormal thyroid profile. We used central tendency and non-parametric measures for description of the sample.
  
  
  RESULTS
  The prevalence of thyroid disease in pregnancy was 33.9% (n = 37), 12.8% (n = 14) with clinical hypothyroidism and 21.1% (n = 23) subclinical hypothyroidism. The 87.1% (n = 95) of patients reported at least one symptom or risk factor history for thyroid disease, only 12.8% (n = 14), had no history or symptoms related to thyroid disease. There is no relationship between a history or symptoms reported and the presence of thyroid disease.
  
  
  CONCLUSIONS
  The prevalence of thyroid clinical and subclinical disease is greater than that reported in the literature. There is not relationship with each risk factor for thyroid disease. Perform universal screening detects almost twice thyroid disease during pregnancy.
