A cohort of 158 patients was identified from 723 patients admitted in 1990 or treated as outpatients in 1991 for affective disorders in three university hospitals in Copenhagen, covering a well-defined catchment area. The cohort was subclassified for seasonal pattern according to DSM-III-R. Meteorological data of temperature, hours of sunshine, rainfall and wind-velocity expressed as mean values/month were obtained from the Institute of Meteorology in Copenhagen. There was no relationship between the annual dis- tribution of affective episodes and meteorological data, neither in the total cohort nor in the subgroup of patients with seasonal patterns The present study does not support the hypothesis that a relation exists between start of a new episode and the season or climatic condition.
从哥本哈根三家大学医院1990年收治或1991年门诊治疗的723例情感障碍患者中确定了158例患者组成队列，这些患者来自明确界定的集水区。根据《精神疾病诊断与统计手册》第三版修订本（DSM-III-R），该队列按季节模式进行了亚分类。从哥本哈根气象研究所获取了温度、日照时长、降雨量和风速的气象数据，以每月平均值表示。情感发作的年度分布与气象数据之间没有关系，无论是在整个队列中还是在有季节性模式的患者亚组中都是如此。本研究不支持新发作的开始与季节或气候条件之间存在关联的假设。
