: Imposed sleep restriction leads to increased feelings of appetite and hedonic eating behaviors (or food rewards). No study to date has assessed home-based measures of sleep with appetite and food rewards exclusively in Black emerging adults (ages 18-28 years), despite higher risks of short sleep and obesity in this population. We examined associations between 6-month changes in sleep with changes in appetite and food reward in Black emerging adults. : Fifteen Black emerging adults (12 females; age, 21 ± 2.5 years; body mass index, 25.7 ± 4.5 kg/m; body fat, 25.8 ± 11.9%) completed two identical 7-day measurement bursts at baseline and 6 months. Sleep (duration, efficiency, and architecture) was captured via 7 days of actigraphy and 2 nights of in-home polysomnography. During a laboratory visit, participants completed appetite measures (desire to eat, hunger, fullness, and prospective food consumption) via visual analog scales before and for 3 h following standard breakfast intake. The food reward for the fat and sweet categories of food was measured before lunch with the Leeds Food Preference Questionnaire. : Fasting fullness scores decreased from baseline to 6 months (-8.9 mm, < 0.01) despite increases in body weight (2.6 kg, < 0.01) and waist circumference (2.4 cm, = 0.03). Increases in actigraph-measured sleep duration were associated with decreases in fasting desire to eat (r = -0.58, = 0.04). Increases in actigraph-measured sleep efficiency were also associated with decreases in explicit liking for sweet foods (r = -0.60, = 0.03). : Our findings suggest that improvements in sleep duration and sleep efficiency may lead to decreased feelings of appetite and food reward in Black emerging adults.
强制睡眠限制会导致食欲增加和享乐性饮食行为（即食物奖励）。尽管该人群存在睡眠不足和肥胖的较高风险，但迄今为止尚无研究专门评估黑人青年（18 - 28岁）基于家庭的睡眠测量与食欲和食物奖励之间的关系。我们研究了黑人青年睡眠6个月的变化与食欲和食物奖励变化之间的关联。15名黑人青年（12名女性；年龄21±2.5岁；体重指数25.7±4.5kg/m²；体脂25.8±11.9%）在基线和6个月时完成了两个相同的7天测量周期。通过7天的活动记录仪和2晚的家庭多导睡眠图记录睡眠情况（持续时间、效率和结构）。在一次实验室访视期间，参与者在标准早餐摄入前及摄入后3小时通过视觉模拟量表完成食欲测量（进食欲望、饥饿感、饱腹感和预期食物摄入量）。午餐前用利兹食物偏好问卷测量脂肪类和甜味类食物的食物奖励。尽管体重增加（2.6kg，P<0.01）和腰围增加（2.4cm，P = 0.03），但空腹饱腹感评分从基线到第6个月下降了（-8.9mm，P<0.01）。活动记录仪测量的睡眠时间增加与空腹进食欲望降低相关（r = -0.58，P = 0.04）。活动记录仪测量的睡眠效率增加也与对甜食的明确喜好降低相关（r = -0.60，P = 0.03）。我们的研究结果表明，睡眠时间和睡眠效率的改善可能会降低黑人青年的食欲和食物奖励感。
