To determine whether there are significant circadian, weekly or lunar variations in self-poisoning presentations and whether patients' names or dates of birth have an influence on the likelihood of self-poisoning by analysing biorhythms, numerology and star sign.
Hunter Valley, Australia.
Consecutive adult patients admitted with self-poisoning between January 1987 and June 1993.
There were 2215 patients admitted. There was a marked circadian variation. Over 6% of all admissions occurred in each of the hours between 6 p.m. and 1 a.m. compared with less than 2% per hour between 5 a.m. and 9 a.m. This pattern was not different for patients with a diagnosis of depression. Numerology, biorhythms and star signs had no significant correlations with self-poisoning, nor was there a significant weekly or yearly variation in presentations. There was a small but statistically significant sex difference in presentations analysed by lunar phases. At the new moon 60% of self-poisonings were in women, compared with 45% when the moon was full. The odds ratios (OR) for women to be admitted at full moon and at new moon were 1.27 (95% confidence interval [CI], 0.92-1.66; P value not significant) and 0.73 (95% CI, 0.57-0.92; P = 0.009) respectively. The mean illumination of the moon at the time of overdose was 50.63% +/- 0.91% for men, compared with 47.45% +/- 0.85% for women (P = 0.014).
The circadian cycle (but not weekly, yearly or mystical cycles) should be taken into account when determining staffing levels for poison information and casualty services. The full moon is protective for women.
通过分析生物节律、数字命理学和星座，确定自我中毒就诊情况是否存在显著的昼夜、每周或月度变化，以及患者姓名或出生日期是否会对自我中毒的可能性产生影响。
澳大利亚猎人谷。
1987年1月至1993年6月期间因自我中毒入院的成年连续患者。
共收治2215例患者。存在明显的昼夜变化。下午6点至凌晨1点之间的每小时入院人数均超过6%，而上午5点至9点之间每小时入院人数不到2%。抑郁症患者的这种模式并无差异。数字命理学、生物节律和星座与自我中毒均无显著相关性，就诊情况也没有显著的每周或年度变化。按月相分析，就诊情况存在微小但具有统计学意义的性别差异。新月时60%的自我中毒患者为女性，满月时这一比例为45%。女性在满月和新月时入院的比值比（OR）分别为1.27（95%置信区间[CI]，0.92 - 1.66；P值无统计学意义）和0.73（95%CI，0.57 - 0.92；P = 0.009）。男性服药过量时的平均月光照度为50.63%±0.91%，女性为47.45%±0.85%（P = 0.014）。
在确定中毒信息和急诊服务的人员配备水平时，应考虑昼夜周期（而非每周、每年或神秘周期）。满月对女性有保护作用。
