A study of menstrual cycle phase on the day of acute admission to a psychiatric hospital for 121 women aged 20-39 showed an unequal distribution of admissions. More admissions than expected took place in the menstrual period, and correspondingly fewer intermenstrually. The difference was significant, and points to a certain degree of cyclicity in female psychiatric disturbance. This cyclicity was not significantly influenced by age, diagnosis, oral contraceptives or tendency for premenstrual symptoms. In the age group 20-39 one and a half times as many men as women are admitted to Danish psychiatric departments. Thus, in view of a common baseline, the most conspicuous feature is, that remarkably few women were admitted intermenstrually.
一项针对121名年龄在20至39岁之间、因急性病入住精神病院的女性的研究表明，入院分布不均衡。月经期入院人数多于预期，而经间期入院人数相应较少。这种差异具有统计学意义，表明女性精神障碍存在一定程度的周期性。这种周期性不受年龄、诊断、口服避孕药或经前症状倾向的显著影响。在丹麦的精神病科，20至39岁年龄组的男性入院人数是女性的1.5倍。因此，鉴于共同的基线，最显著的特征是经间期入院的女性极少。
