Prevalence, Risk Factors of Preserved Ratio Impaired Spirometry in adult in plateau: A Cross-Sectional Study.

ABSTRACT:

Background

Preserved ratio impaired spirometry(PRISm) is considered to be a precursor of COPD. The purpose of our study is to investigate the prevalence and risk factors of PRISm in high-altitude areas.

Methods

The adult residents of Hongyuan County were selected by random sampling method, and the lung function tests, questionnaires, blood tests were conducted. The prevalence of PRISm was compared among different factors of investigation, and binary logistic regression analysis was used to determine the independent influencing factors of PRISm.

Results

627 participants qualified for quality control, the prevalence was 10.06%. The independent factors of PRISm were age 40-49 years old(OR = 4.322,95%CI: 1.149-16.262),age ≧ 60 years (OR = 4.453, 95% CI: 1.003-19.762),Body
