We aimed to understand the relationships of the weather as biometeorological and hospital admissions due to common mental and behavioural disorders in a national setting in recent years.
This is an ecological study. Ten percent of daily hospital admissions from the included hospitals (n = 1618) across Germany that were available between 1 January 2009 and 31 December 2011 (n = 5,235,600) were extracted from Statistisches Bundesamt, Germany. We identified F01-F51 mental ad behavioural disorders by International Classification of Diseases version 10 as the study outcomes. Daily weather data from 64 weather stations covering 13 German States including air temperature, humidity, wind speed, cloud cover, radiation flux and vapour pressure were obtained and generated into physiologically equivalent temperature (PET). We then plotted two-way fractional-polynomial regression.
For the most subtypes, the highest admissions were recorded in spring. There were small peaks in autumn or late winter for a few subtypes as well. Admissions of delirium peaked when PET was at 0 °C. Admissions of personality disorders peaked at the coldest - when PET was at -10 °C. Admissions of schizophrenia and nonorganic sleep disorder peaked when PETs were between 0 and -10 °C while admissions of eating disorders dropped when PETs were above 10 °C. Admissions of depression and anxiety disorder did not vary much across PETs. Moreover, admissions of reaction to stress and dissociate disorder peaked when PETs were between 0 and 10 °C as well.
More medical resources could have been needed for mental health on days when PETs were <10 °C than on other days.
我们旨在了解近年来在全国范围内，作为生物气象因素的天气与因常见精神和行为障碍导致的住院情况之间的关系。
这是一项生态学研究。从德国联邦统计局提取了2009年1月1日至2011年12月31日期间德国境内纳入研究的医院（n = 1618）中10%的每日住院数据（n = 5235600）。我们将国际疾病分类第10版中的F01 - F51精神和行为障碍确定为研究结果。获取了覆盖德国13个州的64个气象站的每日天气数据，包括气温、湿度、风速、云量、辐射通量和水汽压，并将其转换为生理等效温度（PET）。然后绘制双向分数多项式回归图。
对于大多数亚型，春季的住院人数最多。少数亚型在秋季或冬末也有小高峰。谵妄的住院人数在PET为0°C时达到峰值。人格障碍的住院人数在最冷时达到峰值——PET为 - 10°C时。精神分裂症和非器质性睡眠障碍的住院人数在PET为0至 - 10°C之间时达到峰值，而饮食障碍的住院人数在PET高于10°C时下降。抑郁症和焦虑症的住院人数在不同的PET值之间变化不大。此外，应激反应和分离障碍的住院人数在PET为0至10°C之间时也达到峰值。
与其他日子相比，PET < 10°C的日子可能需要更多的心理健康医疗资源。
