Objective : This study attempted to identify differences in performance in daily life activities and participation in leisure activities according to grip strength for the elderly by age and gender group in Korea, and to present basic data on the actual conditions of the elderly in Korea. Methods : Based on the 8th year survey data of the Korean Longitudinal Study of Ageing (KLoSA) collected from August 2020 to December of the same year, 3,789 elderly people over 65 years of age were targeted. The elderly were divided by gender, age, dominant hand, and non-dominant hand to check the grip strength, the degree of performance of basic activities of daily living and instrumental activities of daily living, and the degree of participation in leisure activities, and the relevance of each variable was analyzed. Continuous variable analysis by grip strength for the elderly was analyzed using an independent t-test. Results : In the difference in activities of daily living by the grip strength, there was a significant difference in instrumental activities of daily living of both men and women over the age of 75 (p<.05). The elderly under the age of 75 showed no significant difference by the grip strength in both activities of daily living and instrumental activities of daily living (p>.05). In the difference in leisure by the grip strength, there was a significant difference in the number of travel, tourism, and outing experiences for men of all ages and women aged 75 to 84, and there was a significant difference in the viewing number of movies, performances, concerts, exhibitions, and sports games for men aged 75 to 84, and for women aged 65 to 74, there was a significant difference in the time to participate in hobbies and entertainment-related meetings or programs for women aged 75 to 84 (p<.05). Conclusion : Since the elderly with high grip strength were found to have high activities of daily living and leisure, efforts to improve grip strength are needed to improve the elderly's daily functions.
