<title>Objectives</title>
<p>This study was performed to test the association between lung function and type 2 diabetes mellitus (T2DM) in Korean patients.</p></sec>
<sec>
<title>Methods</title>
<p>Data from the 6<sup>th</sup> Korea National Health and Nutrition Examination Survey (2013 to 2015) was used in this study. There were 3,466 individuals aged between 40 and 80 years, with T2DM, who had a smoking and alcohol status listed, and blood analysis (including blood pressure), were included in this study. Lung function, measured by spirometer ventilatory dysfunction was categorized into 3 patterns: normal, restrictive ventilatory dysfunction, and obstructive ventilatory dysfunction (OVD).</p></sec>
<sec>
<title>Results</title>
<p>Based on multivariate logistic regression analysis, individuals with restrictive ventilatory dysfunction had an increased odds ratio (OR 1.615, 95% CI 1.137–2.294) for T2DM compared with individuals with normal ventilatory function, whereas OVD had no increase in the odds ratio (OR 1.169, 95 % CI 0.857–1.594). Model 1, which adjusted for age and gender, showed that the probability of having restrictive disorder was 1.559 times (95% CI 1.617–2.082) higher for prediabetes patients, and 2.320 times (95% CI 1.611–3.343) higher for T2DM patients, compared to normal individuals. For Model 4, which was fully adjusted for variables, the probability of having a restrictive disorder was 1.837 times higher for T2DM patients (95% CI 1.260–2.679).</p></sec>
<sec>
<title>Conclusion</title>
<p>Restrictive ventilatory dysfunction, but not OVD, was associated independently with T2DM.</p></sec>
