Abstract: Objective To investigate the relationship between extreme temperatures and daily number of cardiovascular deaths in Jinan City, and to provide theoretical basis for preventive measures. Methods Data of daily number of cardiovascular deaths and meteorological variables over the period of 2011-2014 were collected. Cold spells / Heat waves were defined as ≥3 consecutive days with mean temperature ≤5th percentile or ≥95th percentile, respectively. The time-series adjusted Poisson regression was adopted to assess the effects of extreme temperatures on cardiovascular deaths by controlling for lagged effects and other confounders. Results A clear seasonal distribution of daily number of cardiovascular deaths was observed. Extreme temperatures significantly increased the daily number of cardiovascular deaths(P<0.01). Both cold spell and heat wave significantly increased the risk of deaths with RR=1.06(95%CI: 1.03-1.10)and RR=1.03(95%CI: 1.00-1.06), respectively(P<0.05). The elderly group(≥65 years)was more vulnerable to heat wave exposure, while all population regardless of age and gender were vulnerable to cold spell. 山 东 大 学 学 报 (医 学 版)55卷11期 -韩京,等.极端气温对济南市心脑血管疾病死亡的影响 \=- Conclusion Both could spells and heat waves increase the risk of daily cardiovascular death in Jinan City. Our findings suggest that public health policies and interventions during extreme temperatures should target the whole population.
