Cancer Survivors with Low Hand Grip Strength Have Decreased Quality of Life Compared with Healthy Controls: The Korea National Health and Nutrition Examination Survey 2014-2017.

Abstract

BackgroundCancer survivors experience decreased physical function and reduced muscle strength, which leads to lower quality of life (QOL). The hand grip strength (HGS) can be a predictor of poor health-related QOL as a parameter of sarcopenia. The purpose of this study was to investigate the relationship between low HGS and QOL in cancer survivors and healthy controls.MethodsWe analyzed 392 cancer survivors and 1,176 healthy controls from the Korea National Health and Nutrition Examination Survey, 2014–2017. We defined low HGS as 2 standard deviation values for healthy young Korean adults from a previous study. QOL was evaluated using the European Quality of Life Scale-Five Dimensions. A complex sample logistic regression model was used to assess the relationship between each dimension of low HGS and QOL.ResultsThe odds ratios (ORs) for decreased QOL were significantly higher in male cancer survivors with low HGS on self-care (OR, 8.51; 95% confidence interval [CI], 1.69–42.83) and usual activities (OR, 6.63; 95% CI, 1.22–36.03). The ORs for problems in mobility (OR, 5.87; 95% CI, 2.04–16.91), usual activities (OR, 14.46; 95% CI, 3.84–54.44), pain/discomfort (OR, 4.90; 95% CI, 2.00–12.01), and anxiety/depression (OR, 6.43; 95% CI, 2.16–19.12) were significantly high in female cancer survivors with low HGS. However, healthy controls showed no significant relationship between low HGS and QOL.ConclusionFor cancer survivors, low HGS was associated with poor QOL in some domains. Strategies to increase muscle strength must be considered to improve the QOL of cancer survivors.
