DESCRIPTION (provided by applicant): Pediatric obesity has been labeled an epidemic with approximately 33% of children 6-11 years old being either overweight or obese. This marks a dramatic increase in pediatric obesity in the last 20 years. During this same time period, the number of children with insufficient sleep has also risen. Current estimates show that over one-half of school age children have shortened sleep duration. Epidemiological studies have found that shortened sleep duration is associated with increased risk of obesity in children. Experimental studies with adults suggest that less sleep may lead to increased risk for obesity through changes in the neuroendocrine control of hunger and appetite, which may influence food intake. Despite this mounting evidence, to our knowledge, no studies have assessed how an intervention to increase sleep duration affects children's eating behaviors. Furthermore, research has largely neglected to understand how enhancing sleep duration may affect engagement in physical and sedentary activities. The proposed study will therefore build upon previous research by determining whether enhancing sleep duration in children leads to changes in eating and activity behaviors. One hundred four children 8-11 years old who sleep 9 1/2 hours or less each night will be enrolled. Children will be randomly assigned to 1 of 2 conditions: 1) optimize sleep or 2) control (no change in sleep). Families of children in the optimize sleep group will receive effective behavioral strategies to increase sleep duration. At baseline, 2-week and 2-month follow-up, the following will be gathered: sleep duration, dietary intake, physical and sedentary activity, the relative reinforcing value (RRV) of food (i.e., how hard children work for food rewards), and child height and weight. Primary study aims are as follows: 1) to determine if the optimize sleep intervention leads to increases in sleep duration at 2-month follow-up, and 2) to determine if increased sleep leads to changes in caloric intake and percent calories from fat at 2-month follow-up. Secondary study aims will assess changes in the RRV of food, engagement in physical and sedentary activities, and changes in children's zBMI.

描述（由申请人提供）：小儿肥胖被标记为流行病，大约33％的6-11岁儿童超重或肥胖。这标志着过去20年的小儿肥胖症的急剧增加。在同一时期，睡眠不足的儿童人数也增加了。目前的估计表明，超过一半的学龄儿童的睡眠时间缩短了。流行病学研究发现，缩短睡眠持续时间与儿童肥胖风险增加有关。对成年人的实验研究表明，通过改变饥饿和食欲的神经内分泌控制的变化，可能会影响食物摄入量，可能会导致肥胖的风险增加。据我们所知，尽管有这种越来越多的证据，但没有研究评估了增加睡眠时间的干预措施如何影响儿童的饮食行为。此外，研究在很大程度上忽略了，以了解加强睡眠持续时间如何影响在身体和久坐活动中的参与。因此，拟议的研究将通过确定提高儿童睡眠时间是否导致饮食和活动行为的变化来基于先前的研究。每天晚上9 1/2小时睡觉的8-11岁的一百个孩子将入学。儿童将被随机分配到2个条件中的1个条件中：1）优化睡眠或2）控制（睡眠不变）。优化睡眠组中的儿童家庭将获得有效的行为策略，以增加睡眠时间。在基线，为期2周和2个月的随访中，将收集以下内容：睡眠持续时间，饮食摄入量，身体和久坐的活动，食物的相对增强价值（RRV）（即，辛苦的孩子如何为食物奖励工作）以及儿童身高和体重。主要研究目的如下：1）确定优化睡眠干预是否会导致2个月随访时的睡眠持续时间增加，而2）确定睡眠增加是否会导致卡路里摄入量的变化和2个月随访中脂肪的卡路里百分比的变化。二级研究目标将评估食物RRV的变化，参与身体和久坐活动的参与以及儿童ZBMI的变化。
