To determine if sleep difficulties are associated with overweight/obesity status among preadolescents.
A total of 606 (288 males, 318 females) students, ages 11-13 years from southern Ontario, Canada, were included in this analysis. Overweight/obesity status was determined using age- and gender-specific criteria. Sleep difficulty status was determined if the parents reported children 'sometimes' or 'often' experiencing waking up at night, snoring or breathing loudly, and restlessness while sleeping. Logistic regression analysis was used to examine the association of childhood overweight status and sleep difficulties adjusting for age, gender, total physical activity score, total calories intake, maternal education level, and total hours of sleep.
In this sample, 28% of children (76 boys and 95 girls) were identified as being overweight or obese. Relative to their normal-weight peers, overweight and obese individuals reported a higher prevalence of sleep difficulties (10.3% vs. 26.3%, p < 0.0001), reduced hours of sleep (9.4 vs. 9.2 hrs, p < 0.001), and a lower physical activity score (17.2 vs. 19.1, p < 0.01). Using a multiple logistic regression model, in comparison to children reporting none of the three sleep behaviour problems, the odds ratios (95% CI) of being overweight or obese for those having any one, two, or all three sleep behaviour problems were 1.04 (0.46-2.36), 1.35 (0.58-2.10), and 3.52 (1.42-8.74), respectively.
The results suggest that the risk of overweight/obesity is associated with sleep difficulties among preadolescents. Further study is needed to determine the direction of this relationship.
确定青少年前期睡眠困难是否与超重/肥胖状况有关。
本分析纳入了来自加拿大安大略省南部的 606 名（男 288 名，女 318 名）年龄在 11-13 岁的学生。使用年龄和性别特异性标准来确定超重/肥胖状况。如果父母报告孩子“有时”或“经常”夜间醒来、打鼾或呼吸声大以及睡眠不安，则确定睡眠困难状况。使用逻辑回归分析，在调整年龄、性别、总体力活动评分、总卡路里摄入量、母亲教育水平和总睡眠时间后，检查儿童超重状况与睡眠困难的关联。
在该样本中，28%的儿童（男 76 名，女 95 名）超重或肥胖。与正常体重的同龄人相比，超重和肥胖个体报告睡眠困难的发生率更高（10.3%比 26.3%，p < 0.0001），睡眠时间减少（9.4 比 9.2 小时，p < 0.001），体力活动评分降低（17.2 比 19.1，p < 0.01）。使用多因素逻辑回归模型，与报告三种睡眠行为问题均无的儿童相比，报告有一种、两种或三种睡眠行为问题的儿童超重或肥胖的比值比（95%可信区间）分别为 1.04（0.46-2.36）、1.35（0.58-2.10）和 3.52（1.42-8.74）。
结果表明，超重/肥胖的风险与青少年前期的睡眠困难有关。需要进一步的研究来确定这种关系的方向。
