Epidemiological status and influencing factors of chronic obstructive pulmonary disease in the surveillance area of Hubei Province from 2019 to 2020
Objective To investigate the epidemiological status and related influencing factors of chronic obstructive pulmonary disease(COPD)in five disease surveillance points of Hubei Province,China,from 2019 to 2020.Methods A multi-stage stratified cluster sampling method was used to conduct a questionnaire survey,physical measurement,and pulmonary function test on the monitored population.Logistic regression analysis was used to analyze the influencing factors of COPD.Results The prevalence of COPD in the monitored area was 12.59％.After weighting the sample,the prevalence rate in rural areas(15.74％)was significantly higher than that in urban areas(5.90％)(x2=38.542,P＜0.01),and the prevalence rate in males(19.19％)was significantly higher than that in females(3.97％)(x2=93.943,P＜0.01).The COPD prevalence rate increased with age(x2=31.690,P＜0.01),with the highest prevalence rate in the ≥70 age group(23.56％).Logistic regression analysis indicated that males(OR=4.07,95％CI:2.52-6.57),50-＜60 years old(OR=2.75,95％CI:1.45-5.19),60-＜70 years old(OR=4.06,95％C1:2.13-7.73),≥70 years old(OR=5.23,95％CI:2.53-10.82),smokers(OR=1.60,95％CI:1.08-2.40),family history of respiratory disease(OR=1.46,95％CI:1.04-2.07),and presence of any respiratory symptoms(OR=2.74,95％CI:1.88-4.00)were significantly associated with COPD.Conclusions The COPD prevalence in the monitoring regions of Hubei Province is affected by factors such as gender,age,smoking,environment,and genetics.Targeted comprehensive intervention measures should be taken to control the incidence and development of COPD in regions.
