Abstract：
BACKGROUND: Traumatic fractures occur frequently worldwide. However, research remains limited on the association between short-term exposure to temperature and traumatic fractures. This study aims to explore the impact of apparent temperature (AT) on emergency visits (EVs) due to traumatic fractures.
METHODS: Based on EVs data for traumatic fractures and the contemporary meteorological data, a generalized Poisson regression model along with a distributed lag nonlinear model (DLNM) were undertaken to determine the impact of AT on traumatic fracture EVs. Subgroup analysis by gender and age and sensitivity analysis were also performed.
RESULTS: A total of 25,094 EVs for traumatic fractures were included in the study. We observed a wide \"J\"-shaped relationship between AT and risk of traumatic fractures, with AT above 9.5 °C positively associated with EVs due to traumatic fractures. The heat effects became significant at cumulative lag 0-11 days, and the relative risk (RR) for moderate heat (95th percentile, 35.7 °C) and extreme heat (99.5th percentile, 38.8 °C) effect was 1.311 (95% CI: 1.132-1.518) and 1.418 (95% CI: 1.191-1.688) at cumulative lag 0-14 days, respectively. The cold effects were consistently non-significant on single or cumulative lag days across 0-14 days. The heat effects were higher among male and those aged 18-65 years old. The sensitivity analysis results remained robust.
CONCLUSIONS: Higher AT is associated with cumulative and delayed higher traumatic fracture EVs. The male and those aged 18-65 years are more susceptible to higher AT.

摘要：
背景：创伤性骨折在世界范围内经常发生。然而,关于短期温度暴露与创伤性骨折之间的关系的研究仍然有限.这项研究旨在探讨表观温度（AT）对创伤性骨折急诊就诊（EV）的影响。
方法：基于创伤骨折的电动汽车数据和当代气象数据，采用广义泊松回归模型和分布滞后非线性模型(DLNM)来确定AT对创伤性骨折EV的影响.同时进行性别、年龄亚组分析及敏感性分析。
结果：本研究共纳入25,094例创伤性骨折患者。我们观察到AT和创伤性骨折风险之间存在广泛的“J”形关系，由于创伤性骨折，AT高于9.5°C与电动汽车呈正相关。热效应在累积滞后0-11天时变得显著，和中度高温的相对风险(RR)(第95百分位数，35.7°C）和极端高温（99.5百分位数，38.8°C）在累计滞后0-14天时的效果为1.311（95％CI：1.132-1.518）和1.418（95％CI：1.191-1.688），分别。在0-14天的单个或累积滞后日中，寒冷的影响始终不显着。在男性和18-65岁的人群中，热效应更高。敏感性分析结果仍然稳健。
结论：较高的AT与累积性和延迟性较高的创伤性骨折EV相关。男性和18-65岁的人更容易患更高的AT。
