Although the seasonal patterns of admissions of affective disorder have been extensively studied, less attention has been given to the seasonal admission patterns of schizophrenia. The traditional method of aggregating the data over a study period, rather than analysing by year of admission may obscure potentially relevant fluctuations in the seasonal pattern. We examined the year-to-year variation in the admission patterns of schizophrenia and affective disorder in Ireland. Using the National Psychiatric Inpatient Reporting System (NPIRS), individuals admitted with an ICD-9/10 diagnosis of a first episode of schizophrenia or affective disorder during the 6-year period 1989-1994 were identified. Seasonal variations in their admission patterns were examined statistically and graphically. There was a significant seasonal variation in the monthly admission patterns of both schizophrenia and affective disorder. This pattern was more marked for individuals with affective disorder. However, the seasonal pattern was not constant from year to year, particularly for schizophrenia.
尽管情感障碍的住院季节性模式已得到广泛研究，但对精神分裂症的季节性住院模式关注较少。在研究期间汇总数据的传统方法，而非按入院年份进行分析，可能会掩盖季节性模式中潜在的相关波动。我们研究了爱尔兰精神分裂症和情感障碍住院模式的逐年变化。利用国家精神病住院报告系统（NPIRS），确定了在1989 - 1994年6年期间因国际疾病分类第9/10版诊断为精神分裂症或情感障碍首次发作而入院的个体。对他们的住院模式的季节性变化进行了统计和图形分析。精神分裂症和情感障碍的月度住院模式均存在显著的季节性变化。这种模式在情感障碍患者中更为明显。然而，季节性模式并非逐年恒定，尤其是对于精神分裂症而言。
