In adults, poor sleep quality is associated with increased obesogenic eating behaviours; less is known about this relationship in youth. The objectives of this study were to assess the strength of association between fatigue-related quality of life (QoL) and eating behaviours among youth and to describe the associations in participants with percent body fat (%BF) above and below the 90th percentile for sex and age.
Caregiver-reported measures of fatigue (Pediatric QoL Multidimensional Fatigue Scale) and eating behaviours (Child Eating Behaviour Questionnaire) were obtained from participants aged 8-17 years. %BF was measured by iDXA and grouped by sex- and age-specific percentiles. Multiple linear regression adjusting for age, sex and race/ethnicity was used.
Of the 352 participants (49% male), 44.6% had %BF >90th percentile. General, sleep/rest and cognitive fatigue QoL was inversely associated with food approach behaviours: food responsiveness, enjoyment of food, emotional overeating and desire to drink. For participants with %BF >90th percentile, higher general fatigue QoL was associated with higher satiety responsiveness (0.13; 95% confidence interval [CI 0.03, 0.24]). For participants with %BF ≤90th percentile, higher general fatigue QoL was associated with less satiety responsiveness (-0.16; 95% CI [-0.31, -0.01]).
Less fatigue symptoms were associated with less behaviours associated with food approach among paediatric participants. For participants with %BF >90th percentile, less symptoms of general fatigues corresponded with more satiety. Though causation has yet to be established, youth with elevated %BF should be screened for fatigue symptoms and offered counselling on sleep hygiene or a sleep medicine referral to help mitigate weight gain.
在成年人中，睡眠质量差与致肥胖的饮食行为增加有关；而关于青年人群中这种关系的了解较少。本研究的目的是评估青年人群中与疲劳相关的生活质量（QoL）和饮食行为之间的关联强度，并描述身体脂肪百分比（%BF）高于和低于性别及年龄第90百分位数的参与者之间的关联。
从8至17岁的参与者中获取由照料者报告的疲劳（儿童生活质量多维疲劳量表）和饮食行为（儿童饮食行为问卷）测量值。通过双能X线吸收仪测量%BF，并按性别和年龄特定百分位数进行分组。使用对年龄、性别和种族/民族进行校正的多元线性回归分析。
在352名参与者（49%为男性）中，44.6%的人%BF >第90百分位数。总体、睡眠/休息和认知疲劳生活质量与趋近食物行为呈负相关：食物反应性、对食物的喜爱、情绪化暴饮暴食和饮水欲望。对于%BF >第90百分位数的参与者，较高的总体疲劳生活质量与较高的饱腹感反应性相关（0.13；95%置信区间[CI 0.03, 0.24]）。对于%BF≤第90百分位数的参与者，较高的总体疲劳生活质量与较低的饱腹感反应性相关（-0.16；95% CI [-0.31, -0.01]）。
儿科参与者中较少的疲劳症状与较少的趋近食物行为相关。对于%BF >第90百分位数的参与者，较少的总体疲劳症状对应着更强的饱腹感。尽管因果关系尚未确立，但对于%BF升高的青年应筛查疲劳症状，并提供睡眠卫生咨询或转介至睡眠医学专科，以帮助减轻体重增加。
