If association between the decline in physical performance and the decline in pulmonary function is confirmed, the SPPB could be used as a predictor for pulmonary functional declines in aging people because of its convenient use. This study aimed to elucidate the association of the SPPB with the pulmonary function test (PFT) to determine the usefulness of the SPPB as a predictor of PFT decline. The SPPB and PFT were performed on random sample nested in the Korean Longitudinal Study of Aging (KLoSA) panel, a national representative sample of aging people in Korea. Comparisons of adjusted means of forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), forced expiratory ratio (FER) defined as FEV1/FVC between normal and abnormal SPPB groups were performed using the t-test. The association between PFT and SPPB abnormality was examined using multiple logistic regression analysis. Additionally, the associations of gait speed and chair stand time with FEV1 and FVC were examined using multiple linear regression analysis. Five hundred and eighteen subjects were included in analysis. Approximately 43% (222/518) of the subjects were male and 65% (338/518) were 60 years or older. Adjusted means of FEV1 and FER were significantly or marginally lower when SPPB score was abnormal in both overall and non-smoking men (p= 0.009 and 0.053 for overall, p< 0.001 and p< 0.080 for non-smokers), but FVC was lower only in non-smoking men (p= 0.024). Abnormal SPPB score was significantly associated with abnormal PFT regardless of sex. (adjusted odds ratio = OR = 3.76, 95%CI = 1.96-7.22 for men, adjusted OR = 2.11, 95%CI 1.28-3.47 for women). Gait speed was significantly or marginally associated with FEV1 and FVC in participants 60 years or older, regardless of sex. We conclude that abnormal SPPB score was associated with abnormal pulmonary function. Thus, the SPPB has the potential to be used as an early predictor of abnormal pulmonary function in clinical settings and epidemiological study.
