Cataract is the first cause of blindness and the major cause of visual impairment worldwide. Under conditions of global warming, researchers have begun to give attention to the influence of increasing temperature on cataract patients. Our paper aimed to investigate the association between extreme heat and hospital admissions for cataract in Hefei, China. Based on data from the New Rural Cooperative Medical System and National Meteorological Information Center, we used a generalized additive model and a distributed lag nonlinear model to examine the relationship between extreme heat and hospitalizations for cataract, with consideration of cumulative and lagged effects. When current mean temperature was above 28 °C, each 1 °C rise was associated with a 4% decrease in the number of cataract admissions (RR = 0.96, 95% CI = 0.94-0.98). The cumulative relative risk over 11 days of lag was the lowest, which indicated that every 1 °C increase in mean temperature above 28 °C was associated with a 19% decrease in the number of hospital admissions for cataract (RR = 0.81, 95% CI = 0.75-0.88). In subgroup analyses, the negative association between extreme heat and hospital admissions for cataract was stronger among patients who were not admitted to provincial-level hospitals. In conclusion, this paper found that extreme heat was negatively associated with cataract hospitalizations in Hefei, providing useful information for hospitals and policymakers.
白内障是全球失明的首要原因和主要致盲因素。在全球变暖的情况下，研究人员开始关注温度升高对白内障患者的影响。我们的论文旨在研究极端高温与中国合肥白内障住院人数之间的关系。基于新型农村合作医疗制度和国家气象信息中心的数据，我们使用广义加性模型和分布式滞后非线性模型，考虑到累积和滞后效应，研究了极端高温与白内障住院之间的关系。当当前平均温度高于 28°C 时，每升高 1°C，白内障住院人数减少 4%（RR=0.96，95%CI=0.94-0.98）。11 天滞后的累积相对风险最低，这表明平均温度每升高 1°C 以上 28°C，白内障住院人数减少 19%（RR=0.81，95%CI=0.75-0.88）。在亚组分析中，在未入住省级医院的患者中，极端高温与白内障住院人数之间的负相关关系更强。总之，本文发现极端高温与合肥白内障住院人数呈负相关，为医院和决策者提供了有用的信息。
