Abstract

BACKGROUND AND OBJECTIVE

Diabetes mellitus is one of the most common non-communicable diseases (NCDs) and may influence the autonomic nervous system. This study aims to analyze the autonomic control, through heart rate variability (HRV), from community-dwelling elders with (DM+) and without diabetes mellitus (DM-).

MATERIALS AND METHODS

This cross-sectional study, in which 205 elders (≥ 60 years old), from the urban area of Aiquara municipality gave their written consent to participate. HRV data was collected through a Polar RS800CX monitor with a 5-min initial record at rest, followed by the command to quickly stand up.

RESULTS

The mean age was 71 years (SD, 7.32). The population was mostly made up of women 121 (59%), with low or no schooling 123 (60%), and low income 166 (81%). HRV analysis in a frequency domain showed no difference when comparing the two groups of DM+ and DM-. Henceforth in a time domain, the rMSSD showed a median value of 16.09 (interquartile range, 9.91-30.68); pNN50 median of 0.79 (interquartile range, 0.00-6.62), with a statistical significance between the group of DM+ and DM-.

CONCLUSIONS

There is a difference between the studied groups principally in what concerns the time domain, which reflects the parasympathetic activity, suggesting that elders with diabetes mellitus may have a worse parasympathetic control.

摘要

背景与目的

糖尿病是最常见的非传染性疾病之一，可能会影响自主神经系统。本研究旨在通过心率变异性（HRV）分析居住在社区的糖尿病患者（DM+）和非糖尿病患者（DM-）的自主神经控制情况。

材料与方法

这项横断面研究中，来自艾夸拉市市区的205名60岁及以上的老年人书面同意参与。通过Polar RS800CX监测仪收集HRV数据，先在静息状态下初始记录5分钟，然后下达快速站立指令。

结果

平均年龄为71岁（标准差7.32）。人群主要由女性121名（59%）、低学历或无学历者123名（60%）和低收入者166名（81%）组成。频域中的HRV分析显示，DM+和DM-两组之间没有差异。在时域中，rMSSD的中位数为16.09（四分位间距，9.91 - 30.68）；pNN50中位数为0.79（四分位间距，0.00 - 6.62），DM+组和DM-组之间具有统计学意义。
