title: Premenstrual syndrome and fibromyalgia: the frequency of the coexistence and their effects on quality of life.
abstract: OBJECTIVE
  We aimed to investigate the association between Premenstrual syndrome (PMS) and fibromyalgia syndrome (FMS), to assess common symptoms and quality of life (QOL) of them.
  
  
  METHODS
  Patients with PMS formed the PMS group and age-matched healthy normal controls were included in the control group. The diagnosis of the FMS and PMS were based on new American College of Rheumatology FMS criteria and DSM-IV PMS criteria. FMS-related symptoms assessed by visual analog scale and number of tender points (TePs) were analyzed. QOL, PMS severity and FMS severity were assessed with SF-36, fibromyalgia impact questionnaire (FIQ) and premenstrual assessment form (PAF), respectively. Patients with PMS were divided into two subgroups according to coexistence of FMS or not.
  
  
  RESULTS
  The frequency of FMS in PMS and control group were 20 and 0%, respectively (p = 0.002). FMS-related symptoms, number of TePs in the PMS group were higher than those in the control group. The mean mental component summary (MCS) score of SF-36 was low in the PMS group. The mean PAF score in PMS with FMS subgroup was higher than those in without FMS subgroup. The mean physical component summary of SF-36 was low in the PMS patient with FMS. There was correlation between PAF score and FIQ score (r = 0.476, p < 0.001).
  
  
  CONCLUSIONS
  FMS was common among the patients with PMS and frequently seen in the PMS patients having severe premenstrual complaints. Mental QOL was distressed in the patients with PMS but while FMS accompanied to PMS, the physical QOL was decreased.
