Heart rate variability based on risk stratification for type 2 diabetes mellitus

ABSTRACT Objective To evaluate heart rate variability among adults with different risk levels for type 2 diabetes mellitus. Methods The risk for type 2 diabetes mellitus was assessed in 130 participants (89 females) based on the questionnaire Finnish Diabetes Risk Score and was classified as low risk (n=26), slightly elevated risk (n=41), moderate risk (n=27) and high risk (n=32). To measure heart rate variability, a heart-rate monitor Polar S810i® was employed to obtain RR series for each individual, at rest, for 5 minutes, followed by analysis of linear and nonlinear indexes. Results The groups at higher risk of type 2 diabetes mellitus had significantly lower linear and nonlinear heart rate variability indexes. Conclusion The individuals at high risk for type 2 diabetes mellitus have lower heart rate variability.

摘要
研究目的：评估不同2型糖尿病（type 2 diabetes mellitus）患病风险水平成年人的心率变异性（heart rate variability）。
研究方法：基于芬兰糖尿病风险评分（Finnish Diabetes Risk Score）问卷，对130名受试者（其中女性89名）的2型糖尿病患病风险进行评估，将其划分为低风险组（n=26）、轻度升高风险组（n=41）、中度风险组（n=27）及高风险组（n=32）。采用Polar S810i®型心率监测仪采集受试者静息状态下5分钟的RR间期序列，随后对线性及非线性心率变异性指标开展分析。
研究结果：2型糖尿病患病风险更高的组别，其线性与非线性心率变异性指标均显著降低。
研究结论：2型糖尿病高患病风险人群的心率变异性更低。
