目的探讨气象现象、污染水平与每日住院人数的关系方法利用1998- 2009年中国香港特别行政区（SAR）的住院人数、日平均气温、日平均风速、日平均相对湿度、结果在炎热的季节，入场人数增加了4.5%，每增加1摄氏度以上29 C;在寒冷的季节，入场人数增加了1.4%，每减少1摄氏度在8.2-26.9摄氏度的范围内。在亚组分析中，呼吸道和传染病的入院率在极热和极冷期间增加，但心血管疾病的入院率仅在低温期间增加。29摄氏度以上每增加1摄氏度，意外伤害的入院人数就增加1.9%。在寒冷季节，在8.2-26.9摄氏度范围内每下降1摄氏度，心血管疾病和故意伤害的入院率分别上升2.1%和2.4%。入院模式对性别不敏感。儿童呼吸道疾病的入院率在炎热和寒冷的气温下都有所上升，但老年人只有在寒冷的气温下才有所上升。在75岁或以上的人群中，传染病的入院率在两个极端温度期间都有所上升。应制定公共卫生干预措施，保护儿童、老年人和其他弱势群体免受过热和过冷的影响。
Objective To explore the relationship between weather phenomena and pollution levels and daily hospital admissions (as an approximation to morbidity patterns) in Hong Kong Special Administrative Region (SAR), China, in 1998-2009.Methods Generalized additive models and lag models were constructed with data from official sources on hospital admissions and on mean daily temperature, mean daily wind speed, mean relative humidity, daily total global solar radiation, total daily rainfall and daily pollution levels.Findings During the hot season, admissions increased by 4.5% for every increase of 1 C above 29 C; during the cold season, admissions increased by 1.4% for every decrease of 1 degrees C within the 8.2-26.9 degrees C range. In subgroup analyses, admissions for respiratory and infectious diseases increased during extreme heat and cold, but cardiovascular disease admissions increased only during cold temperatures. For every increase of 1 degrees C above 29 degrees C, admissions for unintentional injuries increased by 1.9%. During the cold season, for every decrease of 1 degrees C within the 8.2-26.9 degrees C range, admissions for cardiovascular diseases and intentional injuries rose by 2.1% and 2.4%, respectively. Admission patterns were not sensitive to sex. Admissions for respiratory diseases rose during hot and cold temperatures among children but only during cold temperatures among the elderly. In people aged 75 years or older, admissions for infectious diseases rose during both temperature extremes.Conclusion In Hong Kong SAR, hospitalizations rise during extreme temperatures. Public health interventions should be developed to protect children, the elderly and other vulnerable groups from excessive heat and cold.
