Relationship between Acute Attack of Elderly Bronchial Asthma and Air Pollution, and Climatic Change

Abstract

The study was aimed at investigating the relationship between the acute attack of elderly bronchial asthma and air pollution, and climatic change. 126 Old people who were treated and confirmed with the acute attack of bronchial asthma in Respiratory Outpatient Department of Jilin City Central Hospital were chosen as the research subjects. The relationship between the acute attack of elderly bronchial asthma and air pollution, and climatic change was studied by conducting a questionnaire survey to analyzing the inducing factors. The results showed that the morbidity of acute attack of elderly bronchial asthma in the winter was higher than that in the summer, and there were also differences in it among the different areas, namely, the morbidity in Longtan District (Industrial Area) > that in Changyi District (living area) > that in Fengman District (tourism areas) (P <0.05); the first factor to induce the acute attack of elderly bronchial asthma was the cold stimulation, followed by the air pollution, upper respiratory infection, emotional and unknown. There is a direct relationship between the acute attack of elderly bronchial asthma and air pollution, and climatic change. The acute attack of elderly bronchial asthma can be prevented by improving the elderly patients’ lifestyle to reduce the stimulation of air pollution and climatic change.
