Abstract
BACKGROUND: This study is to longitudinally investigate the association between grip strength and mental health disorders in middle aged and aged population from the Korean Longitudinal Study of Aging. METHODS: Data from the Korean Longitudinal Study of Aging (KLoSA) from 2006 to 2016 was assessed using longitudinal data analysis and out of the 9279 research subjects gathered 1549 (16.7%) participants were reported as Q1 group and 2074 (22.4%) participants were reported as Q5 group. To analyze the association between grip strength and mental health disorders, generalized estimating equation (GEE) model was used. RESULTS: The association between grip strength and cognitive decline was statistically significant, with the following Odds ratio (OR) predicting decreased cognitive decline: OR = 4.99 (p < .0001) for Q1 group vs. Q5 group. The association between grip strength and MMSE and CESD was also statistically significant, with the following estimate (B) predicting decreased MMSE score: B = -0.12 (p < .0001) for Q1 group vs. Q5 group. In terms of CESD, CESD score was higher for Q1 group (B = 0.34, p < .0001) compared to Q5 group. CONCLUSION: This study shows a significant association between grip strength and risk of mental illness in Korean middle aged and aged population. Therefore, grip strength should be given more focus in terms of resistance training programs.
