Numerous studies have reported that admission rates in patients with affective disorders are subject to seasonal variation. Notwithstanding, there has been limited evaluation of the degree to which changeable daily meteorological patterns influence affective disorder admission rates. A handful of small studies have alluded to a potential link between psychiatric admission rates and meteorological variables such as environmental temperature (heat waves in particular), wind direction and sunshine. We used the Kruskal-Wallis test, ARIMA and time-series regression analyses to examine whether daily meteorological variables--namely wind speed and direction, barometric pressure, rainfall, hours of sunshine, sunlight radiation and temperature--influence admission rates for mania and depression across 12 regions in Ireland over a 31-year period. Although we found some very weak but interesting trends for barometric pressure in relation to mania admissions, daily meteorological patterns did not appear to affect hospital admissions overall for mania or depression. Our results do not support the small number of papers to date that suggest a link between daily meteorological variables and affective disorder admissions. Further study is needed.
众多研究报告称，情感障碍患者的入院率存在季节性变化。尽管如此，对于多变的每日气象模式对情感障碍入院率的影响程度，评估仍较为有限。少数小型研究提及了精神科入院率与气象变量之间的潜在联系，如环境温度（尤其是热浪）、风向和日照。我们使用了Kruskal-Wallis检验、自回归积分移动平均模型（ARIMA）和时间序列回归分析，来检验在31年期间，每日气象变量（即风速和风向、气压、降雨量、日照时长、太阳辐射和温度）是否会影响爱尔兰12个地区的躁狂症和抑郁症入院率。尽管我们发现气压与躁狂症入院之间存在一些非常微弱但有趣的趋势，但每日气象模式似乎并未对躁狂症或抑郁症的总体入院情况产生影响。我们的结果不支持迄今为止少数几篇表明每日气象变量与情感障碍入院之间存在联系的论文。还需要进一步研究。
