OBJECTIVE
In the context of childhood obesity progression, sleep patterns have been associated with unhealthy eating habits and energy intake. The association between several eating habits and sleep patterns in children has been recently studied. The aim of this study was to explore the association between sleep patterns, eating habits, and physical fitness in primary school children.
METHODS
A total of 236 children of 6 to 10 years old were recruited. Anthropometric characteristics and body composition were measured, and cardiorespiratory (20-m shuttle run test) and musculoskeletal (squat jump and cycling peak power) fitness tests were performed. Parents were asked to fill out an eating habits questionnaire, and children were classified into 4 categories as a function of the number of eating risk factors they presented. Parents completed a questionnaire about their child's bedtime and waking hours during weekdays and weekends.
RESULTS
Weight (p < .01), waist circumference, and fat mass (p < .05) were significantly higher in late sleepers (27.6 ± 6.3 kg; 60.1 ± 7.6 cm; 19.52 ± 7.44) compared with normal sleepers (25.4 ± 3.7 kg; 58.2 ± 4.9 cm; 17.44% ± 6.23%). None of the physical fitness parameters were associated with sleep duration, bedtime, wake-up time, nor were they significantly different between late and normal sleepers. Bedtime was significantly earlier in children consuming breakfast everyday (08:30 vs. 09:00 PM, p < .01); later in children snacking (09:15 vs. 09:30 PM, p < .05) or watching TV at lunch (10:00 vs 09:30 PM, p < .05). There is an association between the proportion of normal and late sleepers and the accumulation of healthy eating habits (p < .001).
CONCLUSION
Bedtime and sleep timings (normal or late sleepers) are associated with eating habits in primary school children. It seems necessary to consider the number of unhealthy eating habits adopted by children when studying these associations.
目的
在儿童肥胖症进展的背景下，睡眠模式已与不健康的饮食习惯和能量摄入相关联。最近对儿童的几种饮食习惯与睡眠模式之间的关联进行了研究。本研究的目的是探讨小学生的睡眠模式、饮食习惯和身体素质之间的关联。
方法
共招募了236名6至10岁的儿童。测量了人体测量学特征和身体成分，并进行了心肺功能（20米穿梭跑测试）和肌肉骨骼功能（深蹲跳和骑行峰值功率）测试。要求家长填写一份饮食习惯问卷，并根据儿童呈现的饮食风险因素数量将其分为4类。家长完成了一份关于孩子平日和周末就寝时间和起床时间的问卷。
结果
晚睡者（27.6±6.3千克；60.1±7.6厘米；19.52±7.44）的体重（p<.01）、腰围和脂肪量（p<.05）显著高于正常睡眠者（25.4±3.7千克；58.2±4.9厘米；17.44%±6.23%）。没有一项身体素质参数与睡眠时间、就寝时间、起床时间相关，晚睡者和正常睡眠者之间也没有显著差异。每天吃早餐的儿童就寝时间显著更早（晚上8:30对9:00，p<.01）；吃零食的儿童就寝时间更晚（晚上9:15对9:30，p<.05）或午餐时看电视的儿童就寝时间更晚（晚上10:00对9:30，p<.05）。正常睡眠者和晚睡者的比例与健康饮食习惯的积累之间存在关联（p<.001）。
结论
就寝时间和睡眠时间（正常睡眠者或晚睡者）与小学生的饮食习惯相关。在研究这些关联时，似乎有必要考虑儿童采用的不健康饮食习惯的数量。
