Hypothesis
What is the effect of sweltering conditions on mortality from cardiovascular diseases in Huizhou City?
Conclusion
Sweltering conditions increase the mortality of cardiovascular diseases in Huizhou City, particularly affecting women more than men.
Supporting Evidence
- Sweltering conditions increase the risk of death from cardiovascular diseases.
- The greater the temperature-humidity index (THI), the more pronounced the increase in mortality.
- The lag effect of sweltering conditions on mortality peaks at 2-3 days.
- The effect of sweltering on stroke mortality is longer and deeper than that of coronary heart disease.
Takeaway
When it's really hot and humid, more people can get sick and die from heart problems, especially women.
Methodology
The study used descriptive statistics, distributed lag non-linear models (DLNM), and general algebraic modeling systems (GAMs) to analyze mortality data and meteorological data from 2015 to 2021.
Limitations
The study focused only on Huizhou City and did not include individuals from different climatic regions, which may limit the generalizability of the findings.
Participant Demographics
The study included permanent residents of Huizhou City, with a population of about 6,042,900 people.
