Abstract

INTRODUCTION

Whether a late distribution of food intake impacts obesity through increased energy intake remains uncertain and the behavioural characterization of late eating needs to be further investigated. The first objective of this study was to assess the associations between late eating and body mass index (BMI) and total energy intake (TEI), and whether TEI mediates the association between late eating and BMI. The second objective was to assess the associations between late eating and eating behaviour traits or psychosocial factors and whether eating behaviour traits mediate the association between late eating and TEI.

METHODS

Baseline data from 301 individuals (56% women, age = 38.7 ± 8.5 years; BMI = 33.2 ± 3.4 kg/m), who participated in four weight loss studies were used in this cross-sectional study. Total energy intake was assessed using a three-day food record from which the percentage of TEI after 17:00 and after 20:00 was calculated. Eating behaviour traits and psychosocial factors were assessed with questionnaires. Pearson correlations and mediation analyses adjusted for age, sex, underreporting of energy intake, sleep duration and bedtime were performed.

RESULTS

Percent TEI after 17:00 and after 20:00 were associated with TEI ( = 0.13, = 0.03 for both), and TEI mediated the association between percent TEI after 17:00 and BMI ( = 0.01 ± 0.01, 95% CI: 0.001, 0.02). Percent TEI after 17:00 was associated with disinhibition ( = 0.13, = 0.03) and percent TEI after 20:00 was associated with susceptibility to hunger ( = 0.13, = 0.03), stress ( = 0.24, = 0.002) and anxiety ( = 0.28, = 0.0004). In women, disinhibition mediated the association between percent TEI after 17:00 and TEI ( = 3.41 ± 1.43, 95% CI: 0.92, 6.47). Susceptibility to hunger mediated the association between percent TEI after 20:00 and TEI ( = 0.96 ± 0.59, 95% CI: 0.02, 2.34) in men and women.

CONCLUSION

Late eating is associated with TEI and suboptimal eating behaviours which could contribute to explaining the association between timing of food intake and obesity.

摘要

引言

食物摄入时间较晚是否通过增加能量摄入影响肥胖仍不确定，且晚餐行为特征有待进一步研究。本研究的首要目标是评估晚餐时间与体重指数（BMI）和总能量摄入（TEI）之间的关联，以及TEI是否介导晚餐时间与BMI之间的关联。第二个目标是评估晚餐时间与饮食行为特征或心理社会因素之间的关联，以及饮食行为特征是否介导晚餐时间与TEI之间的关联。

方法

本横断面研究使用了301名个体（56%为女性，年龄=38.7±8.5岁；BMI=33.2±3.4kg/m²）的基线数据，这些个体参与了四项减肥研究。使用为期三天的食物记录评估总能量摄入，并计算17:00后和20:00后TEI的百分比。通过问卷调查评估饮食行为特征和心理社会因素。进行了经年龄、性别、能量摄入低报、睡眠时间和就寝时间调整的Pearson相关性分析和中介分析。

结果

17:00后和20:00后的TEI百分比与TEI相关（两者均为r=0.13，P=0.03），且TEI介导了17:00后TEI百分比与BMI之间的关联（β=0.01±0.01，95%CI：0.001，0.02）。17:00后TEI百分比与去抑制相关（r=0.13，P=0.03），20:00后TEI百分比与饥饿易感性相关（r=0.13，P=0.03）、压力相关（r=0.24，P=0.002）和焦虑相关（r=0.28，P=0.0004）。在女性中，去抑制介导了17:00后TEI百分比与TEI之间的关联（β=3.41±1.43，95%CI：0.92，6.47）。饥饿易感性在男性和女性中介导了20:00后TEI百分比与TEI之间的关联（β=0.96±0.59，95%CI：0.02，2.34）。
