Abstract:

Objective To explore the correlation between the daily mean temperature (DMT) and the hospital admissions of the patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD) in different seasons in Changchun City,and to clarify the effect of DMT on AECOPD.Methods The clinical data of 2 564 AECOPD patients and meteorological variables in the same period were collected. A case-crossover study design was used to investigate the association between different meteorological variables and AECOPD in different seasons.Results Under the conditions of adjusting the influences of the daily mean relative humidity (DMRH),daily mean wind speed (DMWS),and daily mean atmospheric pressure (DMAP),when the DMT was increased by 1%,the hospital admissions of the patients with AECOPD in spring and summer were increased by 18.9% (OR=1.189,95%CI=1.152-1.228) and 14.2% (OR=1.142,95%CI=1.074-1.214) (P<0.05),and it was decreased by 9.7%(OR=0.903,95%CI=0.874-0.933) in autumn (P<0.05). But there was no significant association between the DMT and the hospital admissions of the patients with AECOPD in winter (P>0.05).Conclusion The increasing of DMT may be a risk factor of the patients with AECOPD in spring and summer;however,it may be a preventive factor in autumn and winter.

Key words: meteorological variables, daily mean temperature, chronic obstructive pulmonary disease, case-crossover study
