Abstract

Purpose: The effect of the diurnal temperature range (DTR) on human health in diverse geographic areas and the potential confounding factors are not fully understood. Additionally, while a robust association has been reported between temperature and cardiomyopathy (CM), evidence of the impact of DTR is relatively limited. Here, we determined whether an association exists between DTR and CM hospitalisations in vulnerable populations.

Methods: CM admission data (2016-2021) were collected from seven tertiary hospitals in Henan.We used a GAM combined with a distributed lag non-linear model (DLNM) to investigate the delayed effects of DTR on daily hospitalisations for CM.Stratified analysis was performed in subgroups according to sex, age, and season. Attributable fractions (AF) and attributable numbers (AN) were employed to illustrate the disease burden and investigate the association between temperature and DTR.

Results: Overall, 5,757 CM cases were identified. DTR and CM admissions exhibited a non-linear correlation. High DTR (P95: 15.5 °C) and low DTR (P05: 3 °C) increased CM admission risk, with low DTR having a stronger effect. Males and warm seasons were significantly more susceptible to DTR, and low DTR affected youth and adults more than older adults. AF and AN of low DTR on CM admissions were 51% and 2,936, respectively.

Conclusion: Our results revealed a significant association between DTR and CM hospitalisations, providing valuable insights for the development targeted prevention and control measures.

中国河南省昼夜温度范围与心肌病住院风险的关系：一项时间序列研究

目的：不同地理区域的昼夜温差对人体健康的影响及其潜在的混杂因素尚不完全清楚。此外，虽然有报道称温度与心肌病（CM）之间存在密切关联，但有关DTR影响的证据相对有限。在这里，我们确定了弱势人群中DTR和CM住院之间是否存在关联。方法：收集河南省7家三级医院2016-2021年CM住院数据。我们使用GAM结合分布滞后非线性模型（DLNM）来研究DTR对CM每日住院的延迟效应。根据性别、年龄和季节进行分层分析。采用归因分数（AF）和归因数（AN）来说明疾病负担，并探讨温度与DTR的关系。结果：共发现5757例CM病例。DTR与CM录取呈非线性相关。高DTR （P95: 15.5°C）和低DTR （P05: 3°C）增加CM入院风险，低DTR影响更强。雄性和温暖季节对DTR更敏感，低DTR对青年和成人的影响大于老年人。低DTR对CM录取的AF和AN分别为51%和2936。结论：我们的研究结果揭示了DTR与CM住院之间的显著关联，为制定有针对性的预防和控制措施提供了有价值的见解。

期刊介绍： Risk Management and Healthcare Policy is an international, peer-reviewed, open access journal focusing on all aspects of public health, policy and preventative measures to promote good health and improve morbidity and mortality in the population. Specific topics covered in the journal include: Public and community health Policy and law Preventative and predictive healthcare Risk and hazard management Epidemiology, detection and screening Lifestyle and diet modification Vaccination and disease transmission/modification programs Health and safety and occupational health Healthcare services provision Health literacy and education Advertising and promotion of health issues Health economic evaluations and resource management Risk Management and Healthcare Policy focuses on human interventional and observational research. The journal welcomes submitted papers covering original research, clinical and epidemiological studies, reviews and evaluations, guidelines, expert opinion and commentary, and extended reports. Case reports will only be considered if they make a valuable and original contribution to the literature. The journal does not accept study protocols, animal-based or cell line-based studies.
