Recent cross-sectional studies found higher consumption of energy-dense foods among children with short sleep duration; however, longitudinal studies examining changes in sleep and diet over time are needed.
This study aimed to investigate prospective associations between changes in objectively measured sleep duration and alterations in proposed dietary risk factors for obesity in 8-11-year-old Danish children.
Four hundred forty-one children recorded dietary intake during seven consecutive days, along with accelerometer measurements estimating sleep duration at baseline and after ∼200 days.
Baseline sleep duration did not predict changes in dietary intake or vice versa (all P ≥ 0.69). However, 1-h lower sleep duration was associated with higher intake of added sugar (1.59 E%; P = 0.001) and sugar-sweetened beverages (0.90 E%; P = 0.002) after 200 days with no change in energy density of the diet (P = 0.78).
Our results suggest that a negative change in sleep duration is associated with higher intakes of sugar containing foods/beverages.
近期的横断面研究发现，睡眠时长较短的儿童食用能量密集型食物的量更多；然而，需要开展纵向研究来考察睡眠和饮食随时间的变化情况。
本研究旨在调查丹麦8至11岁儿童客观测量的睡眠时长变化与肥胖相关饮食风险因素变化之间的前瞻性关联。
441名儿童连续七天记录饮食摄入量，同时使用加速度计在基线期和大约200天后测量睡眠时长。
基线睡眠时长无法预测饮食摄入量的变化，反之亦然（所有P≥0.69）。然而，睡眠时长降低1小时与200天后添加糖摄入量增加（1.59E%；P=0.001）以及含糖饮料摄入量增加（0.90E%；P=0.002）相关，而饮食的能量密度没有变化（P=0.78）。
我们的结果表明，睡眠时长的负面变化与含糖食物/饮料的摄入量增加有关。
