Correlation between Activity Limitations due to Musculoskeletal Reasons and Grip strength in Korean Early- stage and Late-stage Elderly

초록

This study aims to examine the correlation between activity limitations due to musculoskeletal issues and grip strength among early-stage and late-stage elderly individuals in Korea. Data were extracted from the 7th National Health and Nutrition Examination Survey (2016–2018) conducted by the Korea Centers for Disease Control and Prevention. The study included 8, 374 adults aged 65 years or older who reported activity limitations. Activity limitations and grip strength were analyzed separately for early-stage (65–74 years) and late-stage (75 years and older) elderly individuals. Among the early-stage elderly, 15.4% reported activity limitations, while 23.1% of the late-stage elderly experienced such limitations. The most common causes of activity limitations were back and neck problems, arthritis and rheumatism, and knee and leg pain. In the early-stage elderly with activity limitations, grip strength of the dominant hand was 2.462 times lower than that of individuals without activity restrictions. For the late-stage elderly, grip strength was 1.562 times lower in those with activity limitations compared to those without. Additionally, in the late-stage elderly, grip strength was 3 times lower in cases where activity limitations were due to arthritis. Variability in grip strength based on the specific cause of activity restriction was observed, indicating inconsistencies in the relationship between activity limitations and grip strength across different age groups. The study highlights that while grip strength is generally lower in elderly individuals with activity limitations, the extent of this decrease varies by age and the specific musculoskeletal condition causing the limitation. The relationship between activity restrictions and grip strength is not uniform across all elderly populations, suggesting that activity restrictions do not uniformly lead to decreased grip strength. © (2024), (Elite Scientific Publications).
