摘要:

目的 探讨基于多种临床生物标志物不同组合的表型年龄(PA)模型的构建方法,阐明PA加速的影响因素。 方法 利用美国国家健康与营养检查调查(NHANES)数据库,收集NHANES Ⅲ(1988-1994年)和NHANES Ⅳ(1999-2018年)中研究对象的实足年龄(CA)及白蛋白(ALB)、碱性磷酸酶(ALP)、肌酐(Cr)、血清葡萄糖(Glu)、C反应蛋白(CRP)、白细胞计数(WBC)、淋巴细胞百分比(LYM%)、平均红细胞体积(MCV)和红细胞分布宽度(RDW)9种临床生物标志物的测定结果。在NHANES Ⅲ数据集中,对9种临床生物标志物进行不同子集组合,针对每种组合构建并训练PA模型。在NHANES Ⅳ数据集中应用训练完成的模型计算PA和PA加速。采用Pearson相关分析和组内相关系数(ICC)评估各组合PA和全指标组合模型PA的相关性及其一致性。通过加权线性回归模型分析PA加速的影响因素。基于超文本标记语言(HTML)、层叠样式表(CSS)和JavaScript技术,使用HBuilder软件建立PA动态评估交互式网站。 结果 9种生物标志物共有502种组合,优质组合324种,其中相关系数及ICC大于0.990 0的优质组合有142种。加权线性回归模型结果显示,女性和高教育水平是PA加速的保护因素(β=-0.85,95%CI:-0.97~-0.73;β=-1.14,95%CI:-1.37~-0.90),高体质量指数(BMI)和吸烟是PA加速的风险因素(β=2.45,95%CI:2.26~2.64;β=1.09,95%CI:0.94~1.24),其他西班牙裔比墨西哥裔美国人的PA加速水平高(β=0.84,95%CI:0.55~1.12)。 结论 成功构建了基于多种临床生物标志物不同组合的PA模型,并建立PA动态评估交互式网站,为个体衰老评估提供了有效工具;高BMI和吸烟是加速机体生物衰老的危险因素。

Abstract:

Objective To discuss the construction method of phenotypic age (PA) models based on different combinations of multiple clinical biomarkers, and to clarify the influencing factors of PA acceleration. Methods Using the National Health and Nutrition Examination Survey (NHANES) database, the chronological age(CA) and the measurement results of nine clinical biomarkers including albumin(ALB), alkaline phosphatase(ALP), creatinine(Cr), serum glucose(Glu), C-reactive protein(CRP), white blood cell count(WBC), lymphocyte percent(LYM%), mean cell volume(MCV), and red cell distribution width(RDW) were collected from NHANES Ⅲ (1988-1994) and NHANES Ⅳ (1999-2018). In the NHANES Ⅲ dataset, different subset combinations of the nine clinical biomarkers were constructed, and PA models were built and trained for each combination. The trained models were applied in the NHANES Ⅳ dataset to calculate PA and PA acceleration. Pearson correlation analysis and intraclass correlation coefficient(ICC) were used to assess the correlation and consistency between PA of each combination and PA of the full-indicator combination model. A weighted linear regression model was used to analyze the influencing factors of PA acceleration. An interactive website for dynamic PA assessment was established using HBuilder software based on hyper text markup language(HTML), cascading style sheets(CSS), and JavaScript technologies. Results A total of 502 combinations of the nine biomarkers were generated, and 324 high-quality combinations were identified. Among them, 142 high-quality combinations had correlation coefficients and ICC greater than 0.990 0. The weighted linear regression model results showed that female and higher education level were protective factors for PA acceleration (β=-0.85, 95%CI: -0.97--0.73; β=-1.14, 95%CI:-1.37--0.90), while higher body mass index(BMI) and smoking were the risk factors for PA acceleration (β=2.45, 95%CI: 2.26-2.64; β=1.09, 95%CI: 0.94-1.24). Other Hispanic individuals had significantly higher PA acceleration levels compared with Mexican Americans (β=0.84, 95%CI: 0.55-1.12). Conclusion PA models based on different combinations of multiple clinical biomarkers have been successfully constructed, and an interactive website for dynamic PA assessment has been established, providing an effective tool for individual aging assessment. Higher BMI and smoking are the risk factors that accelerate biological aging of the body.
