title: [Prevalence of premenstrual syndrome in reproductive women and its influential factors].
abstract: OBJECTIVE
  To investigate the prevalence of premenstrual syndrome and its influential factors in reproductive women.
  
  
  METHODS
  A questionnaire was used in 454 reproductive women aged 15-49 in Beijing.
  
  
  RESULTS
  The prevalence of premenstrual syndrome in these women was 30.4%, among which 61.6% was mild, 34.1% moderate, and 4.3% severe. The order of frequency of the symptoms occurring in premenstrual syndrome was irritation, depression, anxiety, diarrhea, lack of concentration and hypersomnia. Women with higher cultural level, greater stress in life (work or study), dysmenorrhea, dislike menstruation and those with depression symptom had a higher incidence than those with lower cultural level, no stress in life, no dysmenorrhea, no dislike toward menstruation and no depression symptom (P < 0.05).
  
  
  CONCLUSIONS
  Premenstrual syndrome is a common disease in reproductive women. Clinical doctors should pay attention and adopt comprehensive measures in order to reduce its incidence and improve the quality of life especially for women with high risk factors.
