Body Mass Index as a Determinant of Lower Limb Function and Community Well-Being in Older Adults: Analysis of 2020 National Older Korean Survey Data

초록

This epidemiological research investigated the relationship between body mass index (BMI) and lower limb function and community well-being among the older population (≥65 years old) in South Korea. Using the 2020 National Survey of Older Koreans (N = 10 097; Mage = 73.6 ± 6.63; MBMI = 23.6 ± 2.61), the study identified underweight (2.3%), normal (72.8%), and obese (24.9%) groups. Findings revealed significant associations between BMI and lower limb function, with underweight individuals facing greater physical challenges (P < .05–.01). Underweight participants were also found to live farther from key community locations, possibly reflecting social and environmental factors (P < .01) and expressed higher dissatisfaction with community environments (Ps < .05–.01). The study emphasizes the need for tailored community planning and health care strategies, focusing on the unique needs of the underweight older adults, considering South Korea’s rapidly increasing older population.
