Mean Hand Grip Strength and Cut-off Value for Sarcopenia in Korean Adults Using KNHANES VI

View Article: PubMed Central - PubMed

ABSTRACT

The purpose of this study was to report age- and gender-specific distribution of the hand grip strength (HGS) using data from the Korea National Health and Nutrition Examination Survey (KNHANES) VI-3 (2015) survey and determine cut-off values for low muscle strength of HGS of Koreans. Of a total of 7,380 participants, 4,553 were subjected to measurements of HGS, including 1,997 men and 2,556 women with a mean age of 49.3 years (range, 19–80 years). The mean ages of men and women were 49.0 and 49.5 years, respectively. HGS was measured using a digital hand dynamometer. It was defined as maximal measured grip strength of the dominant hand. The cut-off value for low muscle strength was defined as the lower 20th percentile of HGS of the study population. Maximum grip strength of men was significantly higher than that of women (40.2 kg in men vs. 24.2 kg in women, P < 0.001). The mean HGS was increased from the age of 19 to 39 years. It was peaked in the age of 35 to 39 years range for both men and women. It was then decreased after 39 years. The cut-off values of HGS in male and female elderly healthy populations were 28.6 and 16.4 kg, respectively. These data might be used as reference values when evaluating sarcopenia and assessing hand injuries.

Mentions: Of 4,553 healthy participants, 1,997 were in men and 2,556 were women. The mean age of this study population was 49.3 ±16.5 years (range, 19–80 years). The mean ages of men and women were 49.0 ±16.8 and 49.5 ±16.3 years, respectively. BMI of men was significantly (P < 0.001) higher than that of women. Education level also showed a significant (P < 0.001) difference between men and women (Table 1). The mean HGS was increased from 19 years to 39 years. It peaked in the range of 35 to 39 years in both men and women. After 39 years, it was decreased. The mean HGS of men was significantly higher than that of women (40.2 kg in men vs. 24.2 kg in women, P < 0.001; Table 2). A total of 935 (20.5%) participants (415 men and 520 women with mean age of 72.2 ± 5.1 and 72.6 ± 5.1 years, respectively) were included in the healthy elderly population to determine the cut-off values of HGS (28.6 kg for men and 16.4 kg for women; Fig. 2).
