Abstract: Background: We investigated population-based data on grip strength, analyzed for demographic factors, and proposed a formula to estimate grip strength that could be generalized to a population with different anthropometric and background characteristics. Methods : This study used a complex, stratified, multistage probability cluster survey with a representative sample of the population. Select household Korean participants ( n = 6577) over age 10 who were able to perform daily tasks without issue were included. Grip strength was measured in both hands, alternately, three times using a digital grip strength dynamometer. Results : There was a curvilinear relationship between grip strength and age, and grip strength was higher in males than females ( p = 0.001). Hand preference significantly affected grip strength ( p = 0.001). Weight and height were positively correlated with strength in both hands ( p = 0.001), but waist circumference was negatively correlated with strength in both hands ( p = 0.001). The intensity of occupational labor did significantly affect grip strength in both hands ( p = 0.001). The formulas for estimating grip strength of each hand are presented as main results. Conclusions: To determine normative data on grip strength, we may consider factors such as occupations with different physical demands, underlying medical conditions, anthropometric characteristics, and unmodifiable factors such as age and sex.
