abstract="BACKGROUND: If an association between a decline in physical performance and subjective QOL is confirmed, the SPPB could be used as a predictor for declining QOL in older people. <br><br>OBJECTIVE: This study aimed to elucidate the association between the short physical performance battery (SPPB) and QOL (EQ-5D) to determine the utility of the SPPB as a predictor of declining QOL. <br><br>METHODS: The SPPB and the EQ-5D test were performed with a random sample of participants nested in the Korean Longitudinal Study of Aging (KLoSA) panel. Comparisons of the adjusted mean scores on the EQ-5D index between normal and abnormal SPPB groups were performed. We selected the quartiles of the EQ-5D index variables for the analysis. The association between the EQ-5D index and SPPB abnormality was examined using multinomial logistic regression analysis. Additionally, the associations between gait speed and chair stand time and the EQ-5D index were examined using the same analysis. <br><br>RESULTS: Four hundred and twenty-two subjects were included in the analysis. The adjusted means for the EQ-5D index were significantly lower when the SPPB score was abnormal (p=0.022 for men, p=0.047 for women). An abnormal SPPB score was significantly associated with the lowest quartile of EQ-5D index score (adjusted OR 3.54 in the lowest quartile for men; adjusted OR 2.50 and 3.37 in the lowest and second quartiles for women). Gait speed was significantly associated with the EQ-5D index for participants of both sexes, but standup time was associated with the EQ-5D index only for men. <br><br>CONCLUSIONS: An abnormal SPPB score was associated with lower QOL. Thus, the SPPB has the potential to be used as an early predictor of declining QOL in clinical settings and epidemiological studies.<p /><p>Language: en</p>",
