Abstract
Calcium and phosphorus intake showed a significant negative relationship with osteosarcopenia and osteosarcopenic adiposity in Korean adults aged 50 years or older. PURPOSE: Osteosarcopenic adiposity (OSA) is a syndrome accompanied by low bone mass, low muscle mass, and adiposity, and the association of the individual OSA components with dietary factors is considerable. The aim of this study was to investigate the association between the intake of dietary calcium and phosphorus and individual and/or combined bone-, muscle-, and fat mass-related abnormalities in body composition (components of OSA). METHODS: This study investigated the relationship between OSA-related components and the intake of calcium and phosphorus in subjects aged 50 years and older (n = 7007) using the Korea National Health and Nutrition Examination Survey (KNHANES) from 2008 to 2011. RESULTS: After adjusting for various confounding factors that affect OSA, the groups with a low calcium intake (below the median value) had a significantly higher risk of osteosarcopenia (OR = 1.768, 95% CI: 1.018-3.073; p = 0.0432) and OSA (OR = 1.505, 95% CI: 1.040-2.180; p = 0.0304) compared to the groups with a high calcium intake (equal to or above the median value). In addition, phosphorus intake showed a significant negative relationship with sarcopenic adiposity. CONCLUSION: In conclusion, the intake of calcium is associated with a lower risk of osteosarcopenia and OSA in Korean adults aged 50 years and older. These results will serve as baseline data on mineral intake for the management of multiple OSA-related components.
