한국 성인에서 악력과 건강 관련 삶의 질과의 연관성

Abstract

We investigated the association between hand grip strength (HGS) and health-related quality of life (HRQOL). Atotal 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. Participantswere classified as normal HRQOL group or impaired HRQOL group according to the EQ-5D responses and theEQ-5D index scores. HGS was measured using Takei dynamometer. Impaired HRQOL group represented lowermean HGS than that of normal HRQOL group. According to the quintile groups of HGS, group with the lowestHGS showed the lowest mean EQ-5D index score in both sexes. And the more HGS increases, the more EQ-5Dindex score increases also (p-value for trend ＜0.001). Men and women with lower grip strength were more likelyto report ‘some’ or ‘extreme problem’ in EQ-5D domains (except anxiety/depression and pain/discomfort domainin men), and also more likely to belong to the lowest 20% level group in EQ-5D index score according to logisticanalyses. Our findings suggest that HGS is associated HRQOL. Low HGS is associated with impaired status ofHRQOL by EQ-5D and EQ-5D index score in Korean men and women. More research is needed to evaluate thespecific plausibility between HGS and HRQOL.
