Abstract

We investigated the association between hand grip strength (HGS) and health-related quality of life (HRQOL). A total number of 9,211 participants from the sixth Korean National Health and Nutrition Examination Survey (2014– 2015) were included. HRQOL was measured by EuroQol-5 dimension (EQ-5D) and EQ-5D index score. Participants were classified as normal HRQOL group or impaired HRQOL group according to the EQ-5D responses and the EQ-5D index scores. HGS was measured using Takei dynamometer. Impaired HRQOL group represented lower mean HGS than that of normal HRQOL group. According to the quintile groups of HGS, group with the lowest HGS showed the lowest mean EQ-5D index score in both sexes. And the more HGS increases, the more EQ-5D index score increases also (p-value for trend <0.001). Men and women with lower grip strength were more likely to report ‘some’ or ‘extreme problem’ in EQ-5D domains (except anxiety/depression and pain/discomfort domain in men), and also more likely to belong to the lowest 20% level group in EQ-5D index score according to logistic analyses. Our findings suggest that HGS is associated HRQOL. Low HGS is associated with impaired status of HRQOL by EQ-5D and EQ-5D index score in Korean men and women. More research is needed to evaluate the specific plausibility between HGS and HRQOL.
