Abstract

Summary

This study investigated the relationship between A body shape index (ABSI) and bone mineral density (BMD) in older Americans and found a negative linear association, which was particularly pronounced in diabetic population. An early focus on ABSI in the elderly population will help in the prevention of osteoporosis.

Objective

A body shape index (ABSI) is an abdominal obesity index developed based on epidemiological statistics and high ABSI indicates that waist circumference (WC) is higher than expected for a given height and weight and corresponds to a more central concentration of body volume. The objective of this study was to determine whether there is a linear or nonlinear relationship between ABSI and total femur bone mineral density (BMD) in older Americans and whether the relationship between the ABSI and total femur BMD varies across populations.

Methods

This cross-sectional study was based on data from the 2007–2018 National Health and Nutrition Examination Survey (NHANES). Weighted multiple linear regression, restricted cubic spline (RCS) curves, subgroup analysis, and interaction tests were used to examine the association between ABSI and total femur BMD.

Results

This study included 2505 older adults. This study found a negative linear correlation between ABSI and total femur BMD (β = -3.2, 95%CI: -5.0, -1.4, p < 0.001). When participants were grouped according to quartiles of ABSI, those in the upper quartile had lower total femur BMD compared to those in the bottom quartile of ABSI. This negative association remained consistent across gender, age, education level, smoking, physical activity and BMI subgroups. However, in the diabetes subgroup, ABSI showed a stronger negative association with total femur BMD.

Conclusions

The study shows a negative linear association between ABSI and total femur BMD in older Americans, with this negative association being stronger in the diabetic population.

体形指数与老年人股骨骨质密度的关系：Nhanes 2007-2018。

本研究调查了美国老年人的体形指数（ABSI）与骨质密度（BMD）之间的关系，发现两者之间存在负线性关系，这种关系在糖尿病人群中尤为明显。尽早关注老年人群的 ABSI 将有助于预防骨质疏松症：体形指数（ABSI）是根据流行病学统计得出的腹部肥胖指数，高体形指数表明腰围（WC）高于给定身高和体重的预期值，相当于身体体积更集中于中心部位。本研究旨在确定美国老年人的 ABSI 与股骨总骨矿物质密度 (BMD) 之间是否存在线性或非线性关系，以及 ABSI 与股骨总骨矿物质密度之间的关系在不同人群中是否存在差异：这项横断面研究基于 2007-2018 年美国国家健康与营养调查（NHANES）的数据。研究采用了加权多元线性回归、受限立方样条曲线（RCS）、亚组分析和交互检验等方法来检验 ABSI 与股骨总骨量之间的关系：这项研究包括 2505 名老年人。研究发现，ABSI 与股骨总骨量呈负线性相关（β = -3.2，95%CI：-5.0，-1.4，p 结论：ABSI 与股骨总骨量呈负线性相关：该研究表明，美国老年人的 ABSI 与总股骨 BMD 之间存在负线性关系，这种负相关在糖尿病人群中更为明显。
