Abstract Background: The association between diurnal temperature range (DTR) and hospitalization for exacerbation of chronic respiratory diseases (CRD) was rarely reported. Objectives: To examine the association between DTR and daily hospital admission for exacerbations of CRD and find out the potential effect of modifications on this association.Method: Data on daily hospitalization for exacerbation of chronic obstructive pulmonary disease (COPD), asthma and bronchiectasis and meteorology measures from 2013 through 2017 were obtained from 21 cities in South China. After controlling the effects of daily mean temperature, relative humidity (RH), particulate matter < 2.5 µm diameter (PM2.5) and other confounding factors, a standard generalized additive model (GAM) with a quasi-Poisson distribution was performed to evaluate the relationships between DTR and daily hospital admissions of CRD in a two-stage strategy. Subgroup analysis was performed to find potential modifications, including seasonality and population characteristics.Result: Elevated risk of hospitalization for exacerbation of CRD (RR=1.09 [95%CI: 1.08 to 1.11]) was associated with interquartile range (IQR) increase in DTR. The effects of DTR on hospital admissions for CRD were strong at low DTR in the hot season and high DTR in the cold season. The relative risk (RR) of hospitalization was 1.11 (95%CI: 1.08 to 1.12) for exacerbations of COPD and 1.09 (95%CI: 1.05 to 1.13) for asthma per IQR increase in DTR. The adverse effect of DTR on hospitalization for bronchiectasis was only observed in female patients (RR=1.06 [95%CI: 1.03 to 1.10]). Conclusion: Our study provided additional evidence for the association between DTR and daily hospitalization for exacerbation of CRD, and these associations are especially stronger in COPD patients and in the cold season than the hot season. Preventive measures to reduce the adverse impacts of DTR were needed for CRD patients.

Abstract Background: Diurnal temperature range (DTR), an important index of climate change, has been widely applied in exploring its effect on cardiovascular disease (CVD). However, few studies have investigated the correlations between DTR and CVD in poor rural areas in China. Methods: Therefore, using a distributed lag nonlinear model and a Poisson regression model, we evaluated this relationship among farmers living in the city of Dingxi (Northwest China). From 2016 to 2019, we obtained outpatient visits for CVD and meteorological data from the New Rural Cooperative Medical Insurance of Gansu Province (NRCMI) and Meteorological Science Data Sharing Service, respectively. The effects of DTR were examined in subgroups stratified by gender and age. Results: We observed nonlinear M-patterns between DTR and CVD hospitalizations among all subgroups when DTR was at the median level (13°C). Estimated effect of a relatively low DTR (5th percentile, 4°C) on the hospital admissions of CVD was stronger than the effect of a relatively high DTR (95th percentile, 19°C). We also found that the adverse effect of DTR on CVD risk was more pronounced in females and elderly than males and younger adults at the low DTR, and vice versa at the high DTR. Conclusions: These results could guide the local authorities to improve CVD preventive strategies in the rural areas.
