Abstract

Autonomic nervous system activity is involved in body weight regulation. We assessed whether the body mass index (BMI) is related to the autonomic nervous system activity as assessed by heart rate variability (HRV). Twenty-five adult normotensive, euglycemic healthy males (M) and females (F) were studied (M/F=13/12). BMI was assessed in each individual. HRV was assessed and the domains of low frequencies (LF, index of the sympathetic modulation) and high frequencies (HF, index of the parasympathetic modulation) were measured. Data were statistically analyzed and are presented as mean+/-s.d. Mean BMI did not correlate with either HF or LF. It inversely related to HF (r=-0.50, P<0.01), whereas its relationship with LF was marginally significant (r=-0.39, P=0.05). The HF in individuals with BMI <20 kg/m(2) was significantly higher from those measured in the remaining subjects (P<0.05). The results support the role of parasympathetic activity in influencing BMI through likely modulation of body weight.

摘要

自主神经系统活动参与体重调节。我们评估了心率变异性（HRV）评估的自主神经系统活动与体重指数（BMI）之间的关系。研究了 25 名成年血压正常、血糖正常的健康男性（M）和女性（F）（M/F=13/12）。对每个人进行 BMI 评估。评估 HRV，并测量低频（LF，交感神经调节指数）和高频（HF，副交感神经调节指数）两个频段。对数据进行统计学分析，并以平均值±标准差表示。平均 BMI 与 HF 或 LF 均无相关性。它与 HF 呈负相关（r=-0.50，P<0.01），而与 LF 的关系则略微显著（r=-0.39，P=0.05）。BMI<20kg/m2 的个体的 HF 明显高于其余受试者（P<0.05）。结果支持副交感活动通过可能调节体重对 BMI 的影响作用。
