Objective To analyze the epidemiological characteristics of elderly hospitalized patients with bronchial asthma in Northern Theater Command General Hospital, and to provide reference for the prevention and treatment of elderly hospitalized bronchial asthma. Methods Clinical data of 724 hospitalized patients with bronchial asthma in Northern Theater Command General Hospital were retrospectively analyzed, and general data of 724 patients with bronchial asthma were collected. According to the age of the patients, they were divided into the elderly group (≥60 years old, n=308) and the non-elderly group (< 60 years old, n=416) for analysis and comparison. Multivariate logistic regression was used to analyze the influencing factors of asthma control and attack severity in the elderly. Results There were 308 elderly patients, including 128 males (41.56%) and 180 females (58.44%). The control of asthma was good in 108 cases (35.06%), general in 136 cases (44.16%) and poor in 28 cases (9.09%). The severity of asthma attack was mild in 16 cases (51.95%), moderate in 184 cases (59.74%), severe in 92 cases (29.87%), and critical in 0 cases (0.00%). There were 416 non-elderly patients, including 224 males (53.85%) and 192 females (46.15%). The asthma control in the non-elderly patients was good in 40 cases (9.62%), general in 140 cases (33.65%), and poor in 132 cases (31.73%). The severity of asthma attack was mild in 100 cases (24.04%), moderate in 208 cases (50.00%), severe in 72 cases (17.31%), and critical in 4 cases (0.96%). There were statistically significant differences between the two groups in gender, smoking status, obesity, education level, basic diseases, asthma control and asthma attack severity (P<0.05). The average age, average hospitalization cost, average length of stay and average course of disease in the elderly group were significantly higher than those in the non-elderly group (P<0.05). Logistic regression analysis showed that age, obesity, and education level were independent risk factors for asthma control (P<0.05). Conclusion The prevalence of elderly asthma patients in Northern Theater Command General Hospital region is high and the condition control is general. Age is an independent risk factor affecting the control of the disease condition and the severity of attacks in elderly asthma patients. In addition, obesity and education level are independent risk factors affecting the control of asthma in elderly patients.
