背景：精神障碍已被发现与凉爽到寒冷气候地区的温度呈正相关，但在温暖地区的关联尚不清楚。本研究探讨年平均气温超过21°C的亚热带城市气温与精神障碍住院的短期关系。方法：采用poisson -广义加性模型和分布滞后非线性模型，对2002 - 2011年香港精神障碍患者的日平均气温、相对湿度和空气污染物进行回归分析，并对季节趋势、长期趋势、星期数和节假日进行调整。分析按疾病类别、性别和年龄组进行分层。结果：44,600例入院患者被纳入分析。温度与总体精神障碍住院率呈正相关（28°C时的累积相对风险vs. 19.4°C（四分位数间距，滞后0-2天）= 1.09(95%置信区间1.03,1.15)），对老年人（≥75岁）的影响最大。在其他地方分类的短暂性精神障碍和偶发性情绪障碍也显示出与温度的强烈正相关。结论：本研究发现，在温暖的亚热带地区，温度与精神障碍入院呈正相关，且在老年人中关系最为显著。随着全球变暖和人口老龄化的双重影响，应该制定有针对性的战略来降低疾病负担。
Background: Mental disorders have been found to be positively associated with temperature in cool to cold climatic regions but the association in warmer regions is unclear. This study presented the short-term association between temperatures and mental disorder hospitalizations in a subtropical city with a mean annual temperature over 21 °C. Methods: Using Poisson-generalized additive models and distributed-lagged nonlinear models, daily mental disorder hospitalizations between 2002 and 2011 in Hong Kong were regressed on daily mean temperature, relative humidity, and air pollutants, adjusted for seasonal trend, long-term trend, day-of-week, and holiday. Analyses were stratified by disease class, gender and age-group. Results: 44,600 admissions were included in the analysis. Temperature was positively associated with overall mental-disorder hospitalizations (cumulative relative risk at 28 °C vs. 19.4 °C (interquartile range, lag 0–2 days) = 1.09 (95% confidence interval 1.03, 1.15)), with the strongest effect among the elderly (≥75 years old). Transient mental disorders due to conditions classified elsewhere and episodic mood disorders also showed strong positive associations with temperature. Conclusion: This study found a positive temperature–mental-disorder admissions association in a warm subtropical region and the association was most prominent among older people. With the dual effect of global warming and an aging population, targeted strategies should be designed to lower the disease burden.
