摘要

研究目的在这项多城市研究中,我们旨在阐明影响高环境温度与急性病救护车出动相关性的城市特定因素:我们使用了日本除东京以外的27个人口超过50万的城市在2012年至2015年5月至9月期间的救护车派遣数据。我们纳入了 20 岁及以上(≥20 岁)的患者,并将他们分为三个年龄组(20-59 岁、60-79 岁和≥80 岁)。我们使用分布式滞后非线性模型探讨了每个年龄组的日相对气温(以气温百分位数表示)和救护车出动风险的城市特定模式,并估算了在 95/99 百分位数气温下与被定义为参考气温 (Tref) 的 77.6 百分位数气温下救护车出动的城市特定相对风险。然后,通过对每个年龄组进行元分析,将估算结果进行合并。我们还应用元回归模型来探讨城市的特定特征是否会改变气温与救护车出动之间的关联:在所有年龄组(≥20 岁)和年龄分层组(20-59 岁、60-79 岁和≥80 岁)中,第 95 百分位数与 Tref 的相对风险分别为 1.14(95% 置信区间 (CI):1.12, 1.16)、1.16(95% CI:1.13, 1.20)、1.13(95% CI:1.10, 1.16)和 1.13(95% CI:1.00, 1.16)。我们观察到,在单身老人、单身母亲和单身父亲家庭比例较高的城市,≥20 岁年龄组的相对风险较高。我们还发现,在蓝领工人比例较高的城市,20-59 岁年龄组的相对风险较高:本研究提供了有关城市特定特征对高温相关健康影响的见解。

[Effect of City-Specific Characteristics on Association between Heat and Ambulance Dispatches].

Objectives: In this multicity study, we aimed to elucidate the city-specific factors affecting the association of high ambient temperature with ambulance dispatches due to acute illnesses.

Methods: We used the data of ambulance dispatches in 27 cities in Japan with more than 500,000 population excluding Tokyo, from May to September from 2012 to 2015. We included patients 20 years and older (≥20 years) and stratified them into three age groups (20-59, 60-79, and ≥80 years). We explored the city-specific pattern of the daily relative temperature (in temperature percentiles) and the risk of ambulance dispatches for each age group using a distributed lag nonlinear model and estimated the city-specific relative risks of ambulance dispatches at the 95/99 percentile temperature compared with the 77.6 percentile temperature defined as the reference temperature (Tref). Then, the estimates were combined by performing meta-analyses for each age group. We also applied meta-regression models to explore whether the city-specific characteristics modified the association of temperature with ambulance dispatches.

Results: The relative risks of the 95th percentile with respect to Tref were 1.14 (95% confidence interval (CI): 1.12, 1.16), 1.16 (95% CI: 1.13, 1.20), 1.13 (95% CI: 1.10, 1.16), and 1.13 (95% CI: 1.00, 1.16), for all-age (≥20) and age-stratified groups (20-59, 60-79, and ≥80 years), respectively. We observed a higher relative risk for the ≥20 years age group in the cities with higher proportions of single-elderly, single-mother, and single-father households. We also found that the relative risk for the 20-59 years age group was higher in the cities with a higher proportion of blue-collar workers.

Conclusions: The present study provides insights into city-specific characteristics modifying heat-related health effects.
