Admissions for mania over a 9-year period in New Zealand were analysed, including data from four separate regions spanning nine degrees in latitude. A spring/summer peak of admissions for mania was found. The four regions showed marked, unexpected variability in seasonality. Regression analyses were performed to test the association of admissions for mania, in the month of admission and the previous month, with mean daily temperature, day length, hours of bright sunshine and mean relative humidity plus the rate of change of each of these variables.
对新西兰9年期间的躁狂症入院情况进行了分析，包括来自四个不同地区的数据，这些地区跨越了9个纬度。发现躁狂症入院存在春/夏高峰。这四个地区在季节性方面表现出明显的、意想不到的差异。进行了回归分析，以检验入院当月和前一个月的躁狂症入院情况与日平均温度、日照时长、日照小时数、平均相对湿度以及这些变量各自的变化率之间的关联。
