BACKGROUND: Parathyroid hormone plays a key role in muscle metabolism and function, yet its precise association with sarcopenia remains controversial. This meta-analysis evaluated the relationship between serum parathyroid hormone levels and the risk of sarcopenia. METHODS: We systematically searched PubMed, Embase, and Web of Science until April 2025 for observational studies on the link between parathyroid hormone levels and sarcopenia. Using random-effects models, we derived pooled odds ratios with 95% confidence intervals and conducted subgroup analyses. Sensitivity analyses were performed to ensure robustness by excluding small or low-quality studies. Study quality was assessed with modified Newcastle-Ottawa scales, and publication bias was checked using funnel plot symmetry. RESULTS: This meta-analysis included 11 studies involving 4,759 participants, with mean ages ranging from 57.5 to 76.4 years and 50.37% of participants being female. Our meta-analysis showed a positive association between serum parathyroid hormone levels and the risk of sarcopenia (odds ratios = 1.10, 95% confidence intervals 1.03-1.17, P < 0.001). Subgroup analyses indicated a consistently positive association across diagnostic definitions and study settings, although the effect size was greater in studies using alternative diagnostic criteria (OR = 1.94, 95% confidence intervals 1.21-3.13) and in hospital-based populations (OR = 2.19, 95% confidence intervals 1.27-3.77).
