To explore the impact of temperature on the number of hospital admissions for stroke in Hengshui City, Hebei Province, and to provide scientific support for relevant prevention and control efforts.
We collected data on the number of hospital admissions for stroke in a region of Hebei Province, daily meteorological data, and air quality data. A distributed lag non-linear model (DLNM) was employed to analyze the effects of temperature on hospital admissions among different genders, age groups, and subgroups.
During the warm season (May to October), temperature had a significant impact on the number of hospital admissions for stroke across various populations. With a cumulative lag of 15 days, the cumulative relative risk (RR) of hospital admission for stroke at a relatively low temperature of 20 ℃ in the warm season was 1.291 (95%CI: 1.030-1.619), at 21 ℃ it was 1.216 (95%CI: 1.016-1.456), and at 22 ℃ it was 1.154(95%CI: 1.003-1.327). For females, the RR was 6.422 (95%CI: 1.910-21.588) at 10 ℃. For the population aged ≥ 65 years, the RR was 4.286 (95%CI: 1.401-13.112) at 10 ℃ and 1.117 (95%CI: 1.016-1.228) at 24 ℃. The relatively low temperature range of 20 ℃-26 ℃ in warm seasons could significantly increase the hospitalization risk of cerebral ischemia subtype (RR: 1.09-2.31). The risk peaked at 20℃, when RR was 2.315 (95%CI: 1.338-4.003).
Temperature during the warm season influences the number of hospital admissions for stroke, with relatively low temperatures (20-22 ℃) in the warm season identified as potential risk factors for stroke patient admissions. Moreover, temperature has specific impacts on females, individuals aged 65 and above, and those with cerebral ischemia.
