目的 血清同型半胱氨酸（Hcy）水平与慢性肾脏病（CKD）的进展相关,但中年人群的非线性关联研究较少,本研究旨在寻找慢性肾脏病危险因素。方法 本研究基于NHANES 1996—2006年数据,纳入5 361例45~65岁参与者,以估算肾小球滤过率（eGFR）<60 mL/（min·1.73 m²）和尿白蛋白/肌酐比值（uACR）≥30 mg/g评估肾功能下降。结果 通过逻辑回归及平滑曲线拟合分析发现,Hcy每升高1 µmol/L,eGFR降低的风险增加8%（OR=1.08,95%CI：1.06~1.10）,uACR升高的风险增加2%（OR=1.02,95%CI：1.00~1.04）。非线性分析显示,Hcy对eGFR的阈值效应拐点为13.4 µmol/L（拐点左侧OR=1.59,95%CI：1.49~1.70;右侧无显著关联）。亚组分析表明,性别、高血压、糖尿病等协变量无交互作用,然而,在敏感性分析中,糖尿病患者中Hcy与eGFR降低的关联更强（交互P=0.015 8）。结论 本研究提示,控制Hcy水平或可延缓美国中年人群（尤其是糖尿病患者）的肾功能衰退。

Objective Elevated serum homocysteine（Hcy）levels are linked to chronic kidney disease（CKD）progression,yet the nonlinear relationship in middle-aged populations remains underexplored．Methods This study analyzed data from 5 361 participants aged 45-65 years in the NHANES 1996-2006 cohort．Renal dysfunction was defined as an estimated glomerular filtration rate（eGFR）<60 mL/min/1.73 m² and urinary albumin-to-creatinine ratio（uACR）≥30 mg/g．Results Logistic regression and smoothed curve fitting revealed that each 1 µmol/L increase in Hcy elevated the risk of reduced eGFR by 8%（OR=1.08,95% CI：1.06-1.10）and uACR by 2%（OR=1.02,95% CI：1.00-1.04）．A nonlinear threshold effect was identified at 13.4 µmol/L,with a stronger association below this threshold（OR=1.59,95% CI：1.49-1.70）and no significant effect above it．Subgroup analyses showed no interactions with gender or hypertension,but a stronger Hcy-eGFR association was observed in diabetics（interaction P=0.0158）．Conclusions These findings suggest that controlling Hcy levels may mitigate renal decline,particularly in diabetic populations,warranting further causal investigations．
