目的

评估温度变异(TV)对心脑血管疾病(CVD)的死亡效应,并进一步量化其归因死亡风险。

方法

收集广州市2013年1月1日至2017年12月31日逐日CVD死亡数、气象资料和空气污染数据,采用广义线性模型分析TV对CVD死亡的风险,并基于风险计算可归因于TV的CVD死亡数和百分比。

结果

TV与CVD死亡呈近线性关系,随着TV的升高,CVD死亡风险增加。以结局前6 d的温度变异作为暴露水平时(TV06)的死亡风险最高。TV06每升高1℃,CVD死亡风险增加2.30%(95%CI:1.42%~3.19%),归因死亡百分比为11.50%(95%CI:10.54%~12.47%)。在亚组分析中,女性的归因死亡百分比(11.85%,95%CI:10.49%~13.22%)稍高于男性(11.10%,95%CI:9.81%~12.41%);65岁以上人群的归因死亡百分比(13.20%,95%CI:12.13%~14.28%)高于0~64岁人群(2.15%,95%CI:-0.01%~4.36%);不同病因中,高血压病的归因死亡百分比最高(21.14%,95%CI:17.71%~24.67%)。

结论

广州市TV可导致CVD死亡风险增加,加重疾病负担。65岁以上人群和高血压病患者的归因死亡风险更高,应针对易感人群,开展有针对性的防护措施。

Objective

To evaluate the effect of temperature variation (TV) on the mortality of cardiovascular diseases (CVD), and further quantify its attributable mortality risk.

Methods

The daily CVD mortality, meteorological data,and air pollution data in Guangzhou from 1st of January 2013 to 31st of December 2017 were collected, and the generalized linear model was used to analyze the relationship between TV and CVD. The number of CVD deaths attributable to TV and the attributable fraction (AF) were calculated from their relationship.

Results

There was a nearly linear relationship between TV and CVD mortality; the mortality increased with the rise of TV, especially exposure to TV in the preceding 6 days (TV06). We estimated 2.30 % (95% confidence interval [CI]: 1.42%-3.19%) increased mortality risk per 1 ℃ increase in TV06, and the AF was 11.50% (95%CI: 10.54%-12.47%). In the subgroup analysis, the AF of CVD mortality in female (11.85%, 95%CI: 10.49%-13.22%) was slightly higher than that of male (11.10%, 95%CI: 9.81%-12.41%); people over 65 years (13.20%, 95%CI: 12.13%-14.28%) was higher than those of 0-64 years (2.15%, 95%CI: -0.01%-4.36%); among cause-specific CVD, hypertension had the highest AF (21.14%, 95%CI: 17.71%-24.67%).

Conclusion

In Guangzhou, the effect of TV on CVD mortality was significant. People over 65 years and patients with hypertension have a higher attributable risk of TV. Those results indicate that targeted protective measures to TV should be implemented for susceptible people.
