Abstract

This cross-sectional study was conducted to examine the association between weather temperature and the number of elderly being hospitalized due to COPD in Danang city in the year of 2019. Five hospitals were selected in our study. On average, daily mean temperature increased from January to June, and then decreased towards December. The highest daily mean temperature was in June, July and August, and the lowest temperature was in January and December. Our result showed for each 1oC increase in temperature, the relative risk of getting COPD increased by 4% among the elderly (95%CI: 0.08% - 8.1%). However, the associations between the number of elderly hospitalized due to COPD and the daily mean temperature, maxium temperature, and minium temperature were not observed.
