Abstract

Consistently it has been reported that a depressed mood and low heart rate variability (HRV) are linked.However, studies have not considered that the association might be explained by dietary behaviour. Theresting inter-beat interval data of 266 adults (Study 1: 156 (51 M), Study 2: 112 (38 M)) were...

Abstract: Consistently it has been reported that a depressed mood and low heart rate variability (HRV) are linked.However, studies have not considered that the association might be explained by dietary behaviour. Theresting inter-beat interval data of 266 adults (Study 1: 156 (51 M), Study 2: 112 (38 M)) were recorded forsix minutes and quantified using linear (HF power: 0.15–0.4 Hz) and nonlinear indices (Sample entropy).Participants also completed the Profile of Mood States and the Three Factor Eating questionnaires. TheAlternative Healthy Eating Index was used to quantify diet quality. In study 1 mood was associated withHRV; an effect partially mediated by diet. Study 2 replicated the finding: disinhibited eating (the tendencyto lose control over one’s eating) and diet sequentially mediated the association between mood and HRV.Diet plays a role in the link between mood and HRV and studies should consider the influence of thisfactor.
