Most evidence on seasonal admission patterns for schizophrenia derives from the Northern Hemisphere with results from the Southern Hemisphere less documented. This study examines seasonal patterns in hospital admissions due to schizophrenia in Queensland, Australia, a large area that has a range of different climatic features. Daily hospital admissions data for people with the primary diagnosis of schizophrenia were collected from Queensland Health Department for the period from January 1996 to December 2015. A generalised linear regression model with Quasi-Poisson distribution was used to assess seasonal admission patterns across different climatic regions. The evidence for seasonality was also explored in subgroups that had different socio-demographic characteristics or history of prior hospitalisation for psychiatric disorders. Overall, a significant winter pattern (RR 1.05, 95%CI 1.01-1.13) was found with a peak in August (RR 1.08, 95%CI 1.03-1.17) in temperate Southeast Queensland. However, the hot humid North and Far North Queensland showed a peak in October (RR 1.10, 95%CI 1.02-1.22). Males (RR 1.11, 95%CI 1.07-1.14), people aged 40-59 years old (RR 1.10, 95%CI 1.05-1.15) and those who had never married (RR 1.09, 95%CI 1.06-1.12), were Australian by birth (RR 1.07, 95%CI 1.04-1.10) or were unemployed (RR 1.13, 95%CI 1.09-1.18) had significantly higher risk for hospital admissions, particularly during the winter months. The seasonal admission pattern for schizophrenia did not change significantly according to admission status and history of outpatient or community psychiatric treatment. The study found some evidence for seasonality of hospital admissions for schizophrenia that differed from northern tropical to southern temperate regions of Queensland.
大多数关于精神分裂症季节性入院模式的证据都来自北半球，而南半球的结果记录较少。本研究检查了澳大利亚昆士兰州因精神分裂症住院的季节性模式，该地区面积很大，气候特征多样。从昆士兰卫生部收集了 1996 年 1 月至 2015 年 12 月期间患有精神分裂症主要诊断的人的每日住院数据。使用具有拟泊松分布的广义线性回归模型来评估不同气候区域的季节性入院模式。还在具有不同社会人口统计学特征或以前因精神疾病住院史的亚组中探索了季节性的证据。总体而言，在温带东南部昆士兰州发现了显著的冬季模式（RR 1.05，95%CI 1.01-1.13），峰值出现在 8 月（RR 1.08，95%CI 1.03-1.17）。然而，炎热潮湿的北部和远北昆士兰州在 10 月出现峰值（RR 1.10，95%CI 1.02-1.22）。男性（RR 1.11，95%CI 1.07-1.14）、40-59 岁的人（RR 1.10，95%CI 1.05-1.15）、从未结婚的人（RR 1.09，95%CI 1.06-1.12）、出生于澳大利亚（RR 1.07，95%CI 1.04-1.10）或失业（RR 1.13，95%CI 1.09-1.18）的人住院的风险显著更高，尤其是在冬季。精神分裂症的季节性入院模式根据入院状态和门诊或社区精神治疗的历史没有显著变化。该研究发现了一些关于精神分裂症住院季节性的证据，这些证据与昆士兰州从北部热带到南部温带的地区有所不同。
