Abstract:
Objective To discuss the relationship between chronic bronchitis and meteorological conditions in Nanjing. Methods Took the record of the recrudescing time of 200 old chronic bronchitis patients for a year. The correlation between the changing of air temperature and pressure and the monthly chronic bronchitis recrudescing in a year was analyzed. The main meteorological conditions by which recrudescing were affected in different season were selected with multiple stepwise correlation analysis. Results There were chronic bronchitis patients recrudescing the whole year, but the most were in winter and the least in summer. The most recrudescing happened in December and April, and the least in May and July. The meteorological factors that affected chronic bronchitis patients recrudescing were air temperature, pressure and wind speed. The relative coefficient of case numbers between 24 hours variations of air temperature and pressure was 0.5762(P=0.0499) and 0.5841(P=0.0461), respectively. Conclusion The steady meteorological conditions are not good for recrudescing of chronic bronchitis patients. And temperature descent and high air pressure are the main meteorological factors that induce chronic bronchitis recrudescing.
