A statistically significant season of birth variation is found in an unselected nationwide sample of 1,939 eating disorders patients, with peak season of birth occurring in May. However, among younger patients (n = 882), peak season of birth is in March, which is statistically significantly different to that expected from the general population season of birth cycle. This finding may imply links between etiology of earlier-onset eating disorders and the psychoses; similar first quarter peak seasonal patterns of birth have been found in schizophrenic and affective psychoses--with birth peaks in January and February. In contrast, for the neuroses and personality disorders, birth peaks have been found to be in June and August, similar to the June birth peak found in this study for later-onset eating disorders (n = 1,057), which was not statistically significantly different to season of birth peaks expected from general population data.
在一项对1939名饮食失调患者的全国性非选择性样本研究中，发现了具有统计学意义的出生季节差异，出生高峰期出现在5月。然而，在较年轻的患者（n = 882）中，出生高峰期在3月，这与一般人群出生周期所预期的情况在统计学上有显著差异。这一发现可能意味着早发性饮食失调的病因与精神病之间存在联系；在精神分裂症和情感性精神病中也发现了类似的第一季度出生高峰季节性模式，出生高峰在1月和2月。相比之下，对于神经症和人格障碍，出生高峰出现在6月和8月，这与本研究中晚发性饮食失调患者（n = 1057）的6月出生高峰相似，与一般人群数据预期的出生季节高峰在统计学上无显著差异。
