摘要

导言生物电阻抗分析（BIA）是临床营养学中使用的一种工具，相位角（PA）等纯电数据具有预后价值。材料和方法对 2014 年 4 月至 2022 年 8 月期间莱昂大学综合医院肥胖和营养科的 1079 名患者以及 86 名健康对照者进行了回顾性观察研究。研究人员收集了人口统计学和人体测量变量，并使用 BIA Tanita MC780® 进行了 BC 分析。结果肥胖组的 PA50KHz 为 5.98°，DRM 为 4.79°，对照组为 6.08°。DRM 组和对照组之间以及 DRM 组和肥胖组之间的 PA 差异具有统计学意义（p < 0.001）。体重指数（BMI）和运动量（PA）之间在总人口（r = 0.452，p < 0.001）和对照组（r = 0.463，p < 0.001）中存在微弱的正相关关系。在总人口（r = -0.408，p < 0.001）、DRM（r = -0.268，p < 0.001）和肥胖（r = -0.342，p < 0.001）中，年龄与 PA 之间呈弱负相关。肥胖组和对照组的 PA 没有明显的统计学差异，肥胖组的 BMI 和 PA 之间也没有相关性。需要进行更多的研究，以便在不同的环境和人群中统一截断点。

Ángulo de fase: diferencias entre desnutrición relacionada con la enfermedad, obesidad y población sana

Introduction

Bioelectrical Impedance Analysis (BIA) is a tool used in clinical nutrition and pure electrical data such as phase angle (PA) has shown prognostic value. It relates resistance and reactance indicating cellular health.

Objective

To determine differences in PA between patients with obesity and disease-related malnutrition (DRM) compared to the healthy population, and to establish associations between PA and other body composition (BC) parameters.

Materials and methods

Retrospective observational study with 1079 patients from the Obesity and Nutrition Department of the Complejo Asistencial Universitario de León between April/2014 and August/2022 as well as 86 healthy controls. Demographic and anthropometric variables were collected and BC was performed with BIA Tanita MC780®. Diagnosis of malnutrition according to GLIM criteria and obesity with body mass index (BMI).

Results

PA50KHz in obesity group is 5.98°, DRM 4.79° and control group 6.08°. Statistically significant differences in PA between DRM and control groups, as well as DRM and obesity (p < 0.001). Weak positive correlation in total population (r = 0.452, p < 0.001) as well as control group (r = 0.463, p < 0.001) between BMI and PA. Weak negative correlation in the total population (r = -0.408, p < 0.001), DRM (r = -0.268, p < 0.001) and obesity (r = -0.342, p < 0.001) between age and PA.

Conclusions

In this study, significantly lower PA was observed in the DRM group than in the control and obesity groups. No statistically significant differences between PA in the obesity and control groups and no correlation between BMI and PA in the obesity group. More studies are needed to standardise cut-off points in different contexts and populations.

期刊介绍： Endocrinología, Diabetes y Nutrición is the official journal of the Spanish Society of Endocrinology and Nutrition (Sociedad Española de Endocrinología y Nutrición, SEEN) and the Spanish Society of Diabetes (Sociedad Española de Diabetes, SED), and was founded in 1954. The aim of the journal is to improve knowledge and be a useful tool in practice for clinical and laboratory specialists, trainee physicians, researchers, and nurses interested in endocrinology, diabetes, nutrition and related disciplines. It is an international journal published in Spanish (print and online) and English (online), covering different fields of endocrinology and metabolism, including diabetes, obesity, and nutrition disorders, as well as the most relevant research produced mainly in Spanish language territories. The quality of the contents is ensured by a prestigious national and international board, and by a selected panel of specialists involved in a rigorous peer review. The result is that only manuscripts containing high quality research and with utmost interest for clinicians and professionals related in the field are published. The Journal publishes Original clinical and research articles, Reviews, Special articles, Clinical Guidelines, Position Statements from both societies and Letters to the editor. Endocrinología, Diabetes y Nutrición can be found at Science Citation Index Expanded, Medline/PubMed and SCOPUS.
