title: Prevalence of premenstrual syndrome and premenstrual dysphoric disorder in a representative cohort of Spanish women of fertile age.
abstract: OBJECTIVE
  To assess the prevalence of premenstrual symptoms, premenstrual syndrome and premenstrual dysphoric disorder in a cohort of women of fertile age representative of the general Spanish population.
  
  
  METHODS
  During the period between November 27th and December 22nd, 2008, a cross-sectional nationwide survey was conducted among a cohort of Spanish women aged between 15 and 49 years. Participants were personally interviewed at home and completed the premenstrual symptoms screening tool.
  
  
  RESULTS
  Of the 2108 participants, 1554 women (73.7%) complained of some of the premenstrual symptoms during the last 12 menstrual cycles. A total of 1415 (91%) women presented isolated symptoms and 139 (8.9%) a moderate/severe premenstrual syndrome. Twenty-four (1.1%) women fulfilled criteria for a diagnosis of premenstrual dysphoric disorder.
  
  
  CONCLUSIONS
  The prevalence of premenstrual symptoms (73.7%) and premenstrual dysphoric disorder (1.1%) in Spanish women aged between 15 and 49 years is similar to that reported in other Western countries. Only women with moderate or severe premenstrual syndrome or premenstrual dysphoric disorder, however, had daily life activities significantly impaired by premenstrual symptoms.
