背景:短睡眠与儿童肥胖有关,可能是通过破坏食欲激素和增加食物反应性。很少有研究客观地检查了儿童早期的这种关联。目标:在86名学龄前儿童(年龄4.0±0.8岁;42%女性;93%非西班牙裔白人,新英格兰北部,美国)。方法:通过家长报告评估儿童的睡眠时间和质量(儿童睡眠习惯问卷,CSHQ)在基线和6个月随访以及在基线通过加速法。父母还填写了儿童饮食行为问卷,以评估儿童的食欲特征。EAH,客观衡量暴饮暴食,在当面访问期间观察到基线。使用线性混合效应或线性回归模型检查睡眠测量与食欲性状之间的关联,在适当的情况下,适应儿童年龄,性别,和家庭收入。结果:每个父母报告的睡眠时间越短与饱腹感反应性越低相关(标准化β=0.14,95%CI:0.01,0.26;p=0.03)。Further,饱腹感反应与EAH呈负相关(Pearson'sr=-0.35,p=0.02)。在加速度计测量的睡眠参数和食欲特征之间没有发现关联,没有睡眠测量与EAH有关。结论:通常睡眠较短,根据父报告,在这个高收入学龄前儿童样本中,横截面与饱腹感反应性降低相关。未来的研究应该考虑社会经济地位是否可以改变睡眠不良对儿童早期食欲特征的影响。
BACKGROUND: Short sleep is consistently linked with childhood obesity, possibly via disrupting appetite hormones and increasing food responsiveness. Few studies have objectively examined this association in early childhood.
OBJECTIVE: To evaluate associations of sleep quantity and quality with child appetitive traits and eating in the absence of hunger (EAH) in a higher-income cohort of 86 preschool-age children (age 4.0 ± 0.8 years; 42% female; 93% non-Hispanic white, Northern New England, US).
METHODS: Children\'s sleep duration and quality were assessed via parent report (Children\'s Sleep Habits Questionnaire, CSHQ) at baseline and 6-month follow-up and via accelerometry at baseline. Parents also completed the Child Eating Behaviors Questionnaire to assess the child\'s appetitive traits. EAH, an objective measure of overeating, was observed at baseline during an in-person visit. Associations between sleep measures and appetitive traits were examined with linear mixed-effect or linear regression models, as appropriate, adjusting for child age, sex, and household income.
RESULTS: Shorter sleep duration per parent report was associated with less satiety responsiveness (standardized ß = 0.14, 95% CI: 0.01, 0.26; p = 0.03). Further, satiety responsiveness was inversely related to EAH (Pearson\'s r = -0.35, p = 0.02). No associations were found between accelerometer-measured sleep parameters and appetitive traits, and no sleep measures were related to EAH.
CONCLUSIONS: Shorter usual sleep, per the parent report, was cross-sectionally associated with reduced satiety responsiveness in this sample of higher-income preschoolers. Future studies should consider whether socioeconomic status may modify the impact of poor sleep on appetitive traits in early childhood.
