Abstract

An excess of schizophrenic births in winter or early spring is a well replicated finding in studies on Western populations. However, there are few studies on Asian populations, and their results are not consistent. We examined the seasonality of schizophrenic births in Japanese subjects (n = 1024) born between 1955 and 1960. Our results showed a significant inverse relationship between temperature and number of schizophrenic births, which is in line with the findings in Western populations. In our data, observed reduction of schizophrenic births in summer was more marked than excess births in winter. We suggest the possibility that birth in summer may have some advantage in brain growth early in life, which results in reducing the risk of developing schizophrenia.

摘要

冬季或早春精神分裂症患者出生人数过多，这在针对西方人群的研究中是一个反复得到验证的发现。然而，针对亚洲人群的研究较少，且结果并不一致。我们调查了1955年至1960年间出生的日本受试者（n = 1024）中精神分裂症患者出生的季节性。我们的结果显示，温度与精神分裂症患者出生人数之间存在显著的负相关关系，这与西方人群的研究结果一致。在我们的数据中，夏季精神分裂症患者出生人数的减少比冬季出生人数的增加更为明显。我们推测，夏季出生可能在生命早期的大脑发育中具有某些优势，从而降低患精神分裂症的风险。
