研究问题
The accelerating global aging population has heightened the focus on sarcopenia as a major condition strongly associated with poor health in middle-aged and older adults.
方法
Throughout the data analysis and manuscript preparation, the authors had no access to any information that could identify individual participants.；Briefly, the survey initially included 17,708 respondents.
核心结论
The majority of participants were married (92.33%), resided in rural areas (64.27%), did not consume alcohol (64.31%), and were nonsmokers (68.35%).；Educational attainment was predominantly at the level of primary school or below (40.74%). ‖ 结论：These exploratory findings should be interpreted cautiously.
局限
The findings demonstrated that both confirmed sarcopenia and its preliminary stage (possible sarcopenia) were significantly associated with an increased risk of depressive symptoms.；The bidirectional relationship between sleep and depression warrants particular attention in interpreting our mediation findings.；Our mediation results should therefore be interpreted with caution, as the single baseline measurement of sleep duration cannot fully capture this dynamic and potentially reciprocal interplay.

A 级证据分级：A 级（同行评议人体研究）
本文属人体研究证据，但需注意：观察性或小样本干预的结论不等于已证实临床获益；效应量与长期安全性仍需更大规模、更长随访的试验验证。
