摘要:


文题释义:
握力体质量比:是通过测量个体的握力和体质量,计算握力占体质量的比值,以反映一个人肌肉力量和体质量的关系。计算公式为:握力成绩(kg)/体质量(kg)。
三酰甘油-葡萄糖指数(TyG):是一种用于评估胰岛素抵抗和代谢综合征的指标,它结合了三酰甘油和空腹血糖的水平,反映个体胰岛素敏感性和代谢状态信息,其计算公式为:TyG指数=Ln[空腹三酰甘油(mg/dL)×空腹血糖(mg/dL)/2]。

背景:肌肉疏松性肥胖是中老年心脑血管疾病患者的重要特点,单纯握力测试可能无法准确评估肌肉质量。骨骼肌作为胰岛素敏感组织,肌肉力量、胰岛素抵抗与心脑血管疾病风险之间可能存在着多重关系。
目的:分析中老年人握力体质量比、握力、坐起测试与心脑血管疾病之间的风险关系,此外探究三酰甘油-葡萄糖指数(TyG)在其中的中介作用。
方法:此次研究来源于中国健康与养老追踪调查,纳入了4 543例无心脑血管疾病史的中老年人,观察在基线调查后的7年内是否新发生了心脑血管疾病。根据基线时的TyG指数、握力、坐起测试时间、握力体质量比进行COX回归分析,此外以TyG指数为中介变量,基于回归分析进行中介效应检验。
结果与结论:①研究人群中有675例在随访中新发生了心脑血管疾病,发病率为14.9%;②风险关系分析中,TyG指数(HR=1.18,95%CI:1.05-1.32)、可能肌少症(HR=1.22,95%CI:1.03-1.44,P=0.02)、坐起测试(HR=1.302,95%CI:1.104-1.536,P=0.002)、握力体质量比(HR=1.288, 95%CI:1.083-1.531,P=0.004)均显著,而握力(HR=0.988,95%CI:0.776-1.258,P=0.92)结果不显著;③此外TyG指数在握力体质量比与新发心脑血管疾病之间存在介导作用(总自然间接效应:HR=1.024,95%CI:1.005-1.043),且作用方向一致,握力体质量比降低增加心脑血管疾病风险的机制中有部分是通过影响TyG指数实现的;④提示中老年人可通过握力体质量比评估肌肉力量与体质量的匹配程度,为评估胰岛素抵抗和心脑血管疾病风险提供了参考。

Abstract: BACKGROUND: Middle-aged and elderly individuals are particularly susceptible to sarcopenic obesity, a significant characteristic observed in patients with cardiovascular and cerebrovascular diseases. Grip strength tests may not provide an accurate assessment of muscle quality. Given that skeletal muscle is an insulin-sensitive tissue, there may be complex relationships between muscle strength, insulin resistance, and cardiovascular diseases.
OBJECTIVE: To analyze the relationship between grip strength to weight ratio (GSWR), grip strength, chair-stand test, and cardiovascular and cerebrovascular diseases in middle-aged and elderly individuals, and to explore the mediating role of the triglyceride-glucose index (TyG) in this context.
METHODS: This study, derived from the China Health and Retirement Longitudinal Study, included a total of 4 543 participants with no history of cardiovascular and cerebrovascular diseases and observed whether there are new-onset cardiovascular and cerebrovascular diseases within 7 years following the baseline survey. COX regression analyses were performed based on TyG index, grip strength, chair-stand test, and GSWR ratio at baseline. In addition, the TyG index was used as a mediating variable to test the mediating effect based on regression analysis.
RESULTS AND CONCLUSION: (1) Of the 4 543 participants, 675 were newly diagnosed with cardiovascular and cerebrovascular diseases, with the incidence of 14.9%. (2) In the multivariate COX proportional hazard regression adjusted for all covariates, TyG [hazard ratio (HR): 1.18, 95% confidence interval (CI): 1.05-1.32], suspected sarcopenia (HR: 1.22, 95% CI: 1.03-1.44, P=0.02), chair-stand test (HR: 1.302, 95% CI: 1.104-1.536, P=0.002), GSWR (HR: 1.288, 95% CI: 1.083-1.531, P=0.004) were all significant, while grip strength (HR: 0.988, 95% CI: 0.776-1.258, P=0.92) was not significant. (3) In addition, TyG was found to mediate the relationship between GSWR and new-onset cardiovascular and cerebrovascular diseases (total natural indirect effect: HR: 1.024, 95% CI: 1.005–1.043), with the direction of effect being consistent. Part of the mechanism by which an increased GSWR raises the risk of cardiovascular and cerebrovascular diseases is through its impact on TyG. To conclude, middle-aged and elderly individuals can assess muscle quality through the GSWR, which provides a reference for evaluating insulin resistance and the risk of cardiovascular and cerebrovascular diseases.

Key words: middle-aged and elderly individuals, muscle strength, grip strength to body weight index, 5-time chair-stand test, triglyceride-glucose index, insulin resistance, cardiovascular disease
