title: Prevalence of premenstrual syndrome and premenstrual dysphoric disorder in a population-based sample in China.
abstract: OBJECTIVE
  To investigate the prevalence of premenstrual syndrome (PMS) and premenstrual dysphoric disorder (PMDD), and the frequency and severity of the symptoms in a population-based sample of Chinese women of reproductive age.
  
  
  METHODS
  Women aged 18-45 years were screened for suspected PMS and PMDD based on the ACOG recommendations for a diagnosis of PMS and diagnostic and statistical manual of mental disorders, fourth edition (DSM-IV). For those who were consistent with PMS diagnostic criteria, the daily record of severity of problems (DRSP) questionnaire was used to assess the symptoms prospectively over 2 months. Participants were then categorized as having no perceived symptoms, mild PMS, moderate PMS, and PMDD, based on a validated algorithm.
  
  
  RESULTS
  Among the study group, the incidence of PMDD was 2.1% and PMS was 21.1%. The most common symptoms were irritability (91.21%), breast tenderness (77.62%), depression (68.31%), abdominal bloating (63.70%) and angry outbursts (59.62%).
  
  
  CONCLUSIONS
  The prevalence of PMS/PMDD and the frequency and severity of the symptoms have their own characteristics in Chinese women.
