Abstract:

Background

Body roundness index (BRI) is a simple measure of central obesity and is strongly associated with cardiovascular disease. People with metabolically obese normal weight (MONW) have a higher risk of cardiovascular disease and are significantly associated with central obesity. The triglyceride glucose (TyG) index is an indicator of insulin resistance. There are limited studies on the relationship between BRI, TyG index and MONW phenotypes in gender-specific elderly populations.

Objective

To explore differences in the risk of prevalence of the BRI and MONW phenotypes in the elderly population by gender, and to explore the TyG index as a potential factor in their differences by gender.

Methods

Permanent residents≥60 years of age who underwent physical examination in 10 cities and counties in Anhui Province from 2017-07-01 to 2021-06-30 were selected as study subjects. A unified questionnaire was used to collect information on gender, age, and disease history of the study subjects, collect information on physical examination and laboratory tests, and calculate BRI and TyG indices. Men and women will be classified into metabolically healthy normal weight (MHNW) phenotype and MONW phenotype according to metabolic status and BMI level, respectively: male MHNW phenotype (n=5 384), male MONW phenotype (n=6 251) ; female MHNW phenotype (n=4 498), female MONW phenotype (n=8 264). Males and females were divided into 4 levels according to BRI quartiles, males: M1, M2, M3, and M4, and females: F1, F2, F3, and F4, respectively. Logistic regression analyses were performed to explore the association between BRI quartile levels and the risk of elevated TyG index and the risk of prevalence of MONW phenotypes respectively, using the Z test was used to compare the differences between the OR value of male and female.

Results

A total of 24 397 investigators were included in this study, including 11 635 (47.7%) males and 12 762 (52.3%) females, with a median age of 67 (64, 70) years, and 9 882 (40.5%) with MHNW phenotype and 14 515 (59.5%) with MONW phenotype. The proportion of hypertension, diabetes mellitus, dyslipidaemia, systolic blood pressure, diastolic blood pressure, TyG index, BRI, fasting glucose (FPG), total cholesterol (TC), triglyceride (TG), and low-density lipoprotein cholesterol (LDL-C) in the elderly population of different genders with MONW phenotype were higher than in the MHNW phenotype, and smoking and high-density lipoprotein cholesterol (HDL-C) were lower than in the MHNW phenotype (P<0.05) ; prevalence of MONW phenotype, hypertension, diabetes mellitus, dyslipidaemia, TyG index, FPG, and TG were higher than those of low level BRI, and HDL-C was lower than those of low level BRI in the elderly population of different genders with high level BRI (P<0.05). The results of univariate Logistic regression analysis showed that the risk of elevated TyG index was increased at BRI M2/F2, M3/F3, and M4/F4 levels in elderly populations of different genders compared with BRI M1/F1 levels (P<0.05) ; and the risk of elevated TyG index increased with increasing BRI levels (Ptrend<0.001 for male, Ptrend<0.001 for female) ; and the risk of elevated TyG index was higher at BRI M2, M3, and M4 levels in older men than at BRI F2, F3, and F4 levels in older women (P<0.05). Multivariate Logistic regression analyses after correction for confounders showed that the risk of MONW phenotype prevalence was increased at the BRI M2/F2, M3/F3, and M4/F4 levels in the elderly population of different genders compared with the BRI M1/F1 level (P<0.05) ; and the risk of MONW phenotype prevalence increased with the increase of the BRI level (Ptrend<0.001 for male, Ptrend<0.001 for female) ; and the risk of the MONW phenotype was higher in older men at BRI levels M2 and M4 than in older women at BRI levels F2 and F4 (P<0.05) .

Conclusion

BRI levels are significantly and positively associated with the risk of the MONW phenotype in older adults of different genders, with high levels of BRI more strongly associated with the risk of the MONW phenotype in older men, with the TyG index being a potential factor contributing to the gender difference.

摘要:

背景

身体圆度指数(BRI)是一种衡量中心性肥胖的简易指标,与心血管疾病密切相关。体质量正常代谢异常(MONW)人群患心血管疾病的风险较高,且与中心性肥胖显著相关。三酰甘油葡萄糖乘积(TyG)指数是反映胰岛素抵抗的指标。目前在不同性别老年人群中BRI、TyG指数和MONW表型的关系研究较为有限。

目的

探讨老年人群BRI与MONW表型患病风险在不同性别中的差异,探究TyG指数作为其不同性别中差异的潜在因素。

方法

选取2017-07-01—2021-06-30在安徽省10个市县区体检的≥60岁的常住居民为研究对象。采用统一的调查表收集研究对象的性别、年龄、疾病史等资料,收集体格检查和实验室检查资料,并计算BRI、TyG指数。将根据代谢状态和BMI水平分别将男性和女性分为体质量正常代谢正常(MHNW)表型和MONW表型:男性MHNW表型(n=5 384)、男性MONW表型(n=6 251);女性MHNW表型(n=4 498)、女性MONW表型(n=8 264)。根据BRI四分位数分别将男性和女性分为4个水平,即男性:M1、M2、M3、M4,女性:F1、F2、F3、F4。采用Logistic回归分析分别探讨BRI四分位水平与TyG指数升高风险以及MONW表型患病风险的关系,采用R(version 4.1.1)软件中的Z检验比较男性和女性OR值之间的差异。

结果

本研究共纳入24 397例调查对象,其中男11 635例(47.7%)、女12 762例(52.3%),中位年龄67(64,70)岁,MHNW表型9 882例(40.5%)、MONW表型14 515例(59.5%)。不同性别MONW表型老年人群高血压比例、糖尿病比例、血脂异常比例、收缩压、舒张压、TyG指数、BRI、空腹血糖(FPG)、总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)高于MHNW表型,吸烟比例、高密度脂蛋白胆固醇(HDL-C)低于MHNW表型(P<0.05);不同性别高水平BRI老年人群MONW表型患病、高血压比例、糖尿病比例、血脂异常比例、TyG指数、FPG、TG高于低水平BRI,HDL-C低于低水平BRI(P<0.05)。单因素Logistic回归分析结果显示,与BRI M1/F1水平相比,不同性别老年人群BRI M2/F2、M3/F3、M4/F4水平TyG指数升高风险均增加(P<0.05);且TyG指数升高风险随着BRI水平升高而增加(男性P趋势<0.001,女性P趋势<0.001);老年男性BRI M2、M3、M4水平TyG指数升高风险高于老年女性BRI F2、F3、F4水平(P<0.05)。校正混杂因素后进行多因素Logistic回归分析结果显示,与BRI M1/F1水平相比,不同性别老年人群BRI M2/F2、M3/F3、M4/F4水平MONW表型患病风险均增加(P<0.05);且MONW表型患病风险随着BRI水平升高而增加(男性P趋势<0.001,女性P趋势<0.001);老年男性BRI M2、M4水平MONW表型患病风险高于老年女性BRI F2、F4水平(P<0.05)。

结论

在不同性别老年人群中,BRI水平与MONW表型患病风险呈正相关,其中老年男性高水平BRI与MONW表型患病风险关联更为密切,TyG指数是引起其性别差异的潜在因素。
