However, the association of hyperhomocysteinemia with decreased skeletal muscle mass remains unclear. We aimed to investigate the association of hyperhomocysteinemia with low skeletal muscle mass (LMM) in asymptomatic adults.Methods: This was a cross-sectional study of 114,583 community-dwelling adults without cancer, stroke, or cardiovascular diseases who underwent measurements of plasma homocysteine and body composition analysis from 2012 to 2018. Hyperhomocysteinemia was defined as &gt;15 \u03bcmol\/L. Skeletal muscle mass index (SMI) was calculated based on appendicular muscle mass (kg)\/height (m)&lt;sup&gt;2&lt;\/sup&gt;. Participants were classified into three groups based on SMI: \u201cnormal,\u201d \u201cmildly low,\u201d and \u201cseverely low.\u201dResults: The prevalence of hyperhomocysteinemia was the highest in subjects with severely LMM (12.9%), followed by those with mildly LMM (9.8%), and those with normal muscle mass (8.5%) (P for trend &lt;0.001). In a multivariable logistic regression model, hyperhomocysteinemia was significantly associated with having a mildly LMM (odds ratio [OR], 1.305; 95% confidence interval [CI], 1.224 to 1.392) and severely LMM (OR, 1.958; 95% CI, 1.667 to 2.286), respectively. One unit increment of log-transformed homocysteine was associated with 1.360 and 2.169 times higher risk of having mildly LMM and severely LMM, respectively.Conclusion: We demonstrated that elevated homocysteine has an independent association with LMM in asymptomatic adults, supporting that hyperhomocysteinemia itself can be a risk for decline in skeletal musculature.<\/jats:p>","DOI":"10.3803\/enm.2021.1202","type":"journal-article","created":{"date-parts":[[2022,2,9]],"date-time":"2022-02-09T03:27:52Z","timestamp":1644377272000},"page":"333-343","update-policy":"https:\/\/doi.org\/10.3803\/crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Association
