Purpose: This study aimed to evaluate the prevalence, trends, and factors of preserved ratio with impaired spirometry (PRISm) by using a nationally representative sample. Patients and methods: The datasets of the Korea National Health and Nutrition Examination Survey 2010–2019 were used: of total 32,949 participants aged ≥40 and no missing data on spirometry, 24,523 with normal, 4,623 with obstructive, and 3,803 with PRISm were identified. PRISm was defined as FEV
1 /FVC ≥70% and FEV1 % of the predicted value (%pred) <80. PRISm-lower limit of normal (LLN) was defined when FEV1 /FVC ≥LLN and FEV1 2, metabolic syndrome, hypertriglyceridemia, abdominal obesity, low HDL-choleterol, hypertension, and diabetes were associated with the increased probability of PRISm. Conclusion: Whenever a PRISm pattern is identified in a clinical context, it may be necessary to measure absolute lung volumes to investigate underlying physiological abnormalities and to identify factors that is modifiable.
