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: In this study, the mean HGSs of Korean men and women older than 20 years were 40.2 kg and 24.2 kg, respectively. Comparing our data to those of other countries, data from France (46.2 kg in men and 28.2 kg in women) and Canada (44.1 kg in men and 26.4 kg in women) were higher than our results. However, data from Taiwan (35kg in men and 21.2 kg in women) and Japan (36.6 kg in men and 23.7 kg in women) were lower than our findings (Fig. 3A and B). (12131415) Comparing other studies performed in Korea, our findings were slightly lower than those of other studies using Koreans. For example, Shim et al. (16) measured HGS using 300 healthy participants between 20 and 77 years of age and reported that the mean HGS was 43 kg in men and 26.6 kg in women. Han et al. (17) have reported that the mean HGS using 515 healthy participants (234 men and 281 women) between 10 and 84 years was 41.8 kg in men and 25.2 kg in women. Lee et al. (18) have reported that the mean HGS using 479 healthy participants (248 men and 231 women) between 20 and 74 years was 40.8 kg in men and 25.1 kg in women. Although measurement methods, instrument, and participant's demographics were diverse in most studies, these studies all showed that HGSs had ethnic differences.
