This study characterizes the positive relationship between daily temperature and bipolar disorder in a cohort of Taiwanese psychiatric inpatients.
Meteorological data, provided by the Central Weather Bureau (CWB) of Taiwan, were interpolated to create representative estimates of mean diurnal temperatures for 352 townships. Psychiatric inpatient admissions enrolled in the national health-care insurance system were retrieved from the 1996-2007 Psychiatric Inpatient Medical Claim (PIMC) dataset. The generalized linear mixed models with Poisson distribution were used to evaluate the relative risks of mean diurnal temperature with respect to increased admissions for bipolar disorder, while adjusting for internal correlations and demographic covariates.
Increased relative risks of bipolar disorder admissions were associated with the increasing trends of temperature over 24.0 °C (50th ‰), especially for adults and females. The highest daily diurnal temperatures above 30.7 °C (99th ‰) had the greatest risks of bipolar hospitalizations.
Understanding the increase of bipolar disorder admissions occurring in extreme heat is important in the preparation and prevention of massive recurrences of bipolar episodes.
本研究旨在描述台湾地区精神科住院患者中，每日气温与双相情感障碍之间的正相关关系。
气象数据由台湾中央气象局（CWB）提供，用于对 352 个乡镇的日平均气温进行插值，以得出有代表性的估计值。从 1996 年至 2007 年的精神科住院医疗保险索赔（PIMC）数据集中检索了参加国家医疗保险计划的精神科住院患者入院情况。使用具有泊松分布的广义线性混合模型来评估相对于双相情感障碍入院人数增加的日平均温度的相对风险，同时调整了内部相关性和人口统计学协变量。
双相情感障碍入院的相对风险增加与 24.0°C 以上（第 50 个百分位数）的温度升高趋势相关，尤其是在成年人和女性中。最高的每日日温差超过 30.7°C（第 99 个百分位数），与双相住院的风险最高。
了解在极端高温下双相情感障碍入院人数的增加，对于预防双相情感障碍发作的大规模复发的准备和预防非常重要。
