Association of physiological recovery with nutrition has scarcely been studied. We investigated whether physiological recovery during sleep relates to eating habits, i.e., eating behaviour and diet quality.
Cross-sectional baseline analysis of psychologically distressed adults with overweight (N = 252) participating in a lifestyle intervention study in three Finnish cities. Recovery measures were based on sleep-time heart rate variability (HRV) measured for 3 consecutive nights. Measures derived from HRV were 1) RMSSD (Root Mean Square of the Successive Differences) indicating the parasympathetic activation of the autonomic nervous system and 2) Stress Balance (SB) indicating the temporal ratio of recovery to stress. Eating behaviour was measured with questionnaires (Intuitive Eating Scale, Three-Factor Eating Questionnaire, Health and Taste Attitude Scales, ecSatter Inventory™). Diet quality was quantified using questionnaires (Index of Diet Quality, Alcohol Use Disorders Identification Test Consumption) and 48-h dietary recall.
Participants with best RMSSD reported less intuitive eating (p = 0.019) and less eating for physical rather than emotional reasons (p = 0.010) compared to those with poorest RMSSD; participants with good SB reported less unconditional permission to eat (p = 0.008), higher fibre intake (p = 0.028), higher diet quality (p = 0.001), and lower alcohol consumption (p < 0.001) compared to those with poor SB, although effect sizes were small. In subgroup analyses among participants who reported working regular daytime hours (n = 216), only the associations of SB with diet quality and alcohol consumption remained significant.
Better nocturnal recovery showed associations with better diet quality, lower alcohol consumption and possibly lower intuitive eating. In future lifestyle interventions and clinical practice, it is important to acknowledge sleep-time recovery as one possible factor linked with eating habits.

生理恢复与营养之间的关联鲜有研究。我们调查了睡眠期间的生理恢复是否与饮食习惯相关，即饮食行为和饮食质量。
对芬兰三个城市中参与生活方式干预研究的超重心理困扰成年人（N = 252）进行横断面基线分析。恢复指标基于连续三晚测量的睡眠时间心率变异性（HRV）。从HRV得出的指标有：1）RMSSD（逐差均方根），表明自主神经系统的副交感神经激活；2）压力平衡（SB），表明恢复与压力的时间比。饮食行为通过问卷测量（直觉饮食量表、三因素饮食问卷、健康与口味态度量表、ecSatter量表™）。饮食质量通过问卷（饮食质量指数、酒精使用障碍识别测试消耗量）和48小时饮食回顾进行量化。
与RMSSD最差的参与者相比，RMSSD最佳的参与者报告的直觉饮食较少（p = 0.019），因身体而非情绪原因进食较少（p = 0.010）；与SB较差的参与者相比，SB良好的参与者报告的无条件进食许可较少（p = 0.008），纤维摄入量较高（p = 0.028），饮食质量较高（p = 0.001），酒精消耗量较低（p < 0.001），尽管效应量较小。在报告白天工作时间规律的参与者（n = 216）的亚组分析中，只有SB与饮食质量和酒精消耗量的关联仍然显著。
夜间恢复较好与饮食质量较好、酒精消耗量较低以及可能较低的直觉饮食有关。在未来的生活方式干预和临床实践中，认识到睡眠时间恢复是与饮食习惯相关的一个可能因素很重要。
