Hand grip strength (HGS) is a means to assess health status and physical abilities indirectly. Various factors are known to be related to HGS, but data on the factors influencing HGS in the Korean population are lacking. Recently, the Korea National Health and Nutrition Examination Survey (KNHANES) conducted by the Korea Centers for Disease Control and Prevention surveyed social status, nutrition, physical status, and other medical history including HGS. This study aimed to investigate the social, physical, and individual health behavior factors associated with low HGS in the elderly Korean population. This population-based cross-sectional study was based on the 2014-2016 KNHANES. Community-dwelling Korean elderly (aged ≥65 years) were included in this survey. The relationship between HGS and socioeconomic status, nutrition, exercise, and other clinical characteristics were analyzed using multivariate logistic regression. The sample size was 3,634 (weighted: 6,006,406). Elderly men and women with low HGS showed lower body mass index, reduced physical activity and lower education level. Among elderly men, excessive carbohydrate and inadequate protein intake were observed in the low HGS group. Meanwhile, older women who did not drink alcohol and had diabetes were at higher risk of low HGS. In conclusion, various physical, nutritional, socioeconomic and comorbidity statuses were seemed to be the factors associated with HGS in Korean elderly. However, further cohort or case-control study will be necessary to determine the causal relationship of those factors and HGS.
握力是一种间接评估健康状况和身体能力的方法。已知许多因素与握力有关，但缺乏关于韩国人群影响握力的因素的数据。最近，由韩国疾病控制和预防中心进行的韩国国家健康和营养检查调查（KNHANES）调查了社会地位、营养、身体状况和其他包括握力在内的医疗史。本研究旨在调查与韩国老年人群握力低相关的社会、身体和个人健康行为因素。这项基于人群的横断面研究基于 2014-2016 年的 KNHANES。本调查纳入了居住在社区的韩国老年人（年龄≥65 岁）。使用多变量逻辑回归分析握力与社会经济地位、营养、运动和其他临床特征之间的关系。样本量为 3634 人（加权：6006406 人）。握力低的老年男性和女性的体重指数较低，体力活动减少，受教育程度较低。在老年男性中，握力低的组中存在碳水化合物摄入过多和蛋白质摄入不足的情况。另一方面，不饮酒且患有糖尿病的老年女性握力低的风险较高。总之，各种身体、营养、社会经济和合并症状况似乎是与韩国老年人握力相关的因素。然而，需要进一步的队列或病例对照研究来确定这些因素与握力之间的因果关系。
