Associations Between Vitamin D Deficiency and Sarcopenia in South Korean Adults: Based on the 2022 Korea National Health and Nutrition Examination Survey.

ABSTRACT: Background/Objectives: Although vitamin D has been associated with sarcopenia in older adults, evidence across age groups remains limited. This study evaluated the relationship between vitamin D deficiency (VDD) and muscle health in Korean adults aged ≥19 years. Methods: Data utilized in this study were obtained from the 2022 Korea National Health and Nutrition Examination Survey IX-1. Serum 25-hydroxyvitamin D [25(OH)D] levels were analyzed in relation to appendicular skeletal muscle mass (ASM), grip strength, and sarcopenia using multivariable regression models. Results: Among 3,920 participants, 46.5% had VDD, with the highest prevalence observed in younger adults. After adjusting for age, body mass index, energy intake, and other confounding factors, serum 25(OH)D
