Studies mainly performed in adults have shown an association between the amount of sleep and obesity.
To determine if there is an association between nocturnal sleep deprivation during the week and the weekend, eating habits, physical activity and nutritional status among Chilean schoolchildren.
POPULATION, MATERIAL AND METHODS: Crosssectional study. An anthropometric assessment was done among 6-11 year-old students; the Pittsburgh Sleep Quality Index (PSQI) was used among parents to measure their children's quality of sleep; they were asked about eating habits and physical activity.
One thousand eight hundred and ten schoolchildren of both sexes, attending public schools in Santiago, were assessed. Out of these schoolchildren, 49.9% slept fewer hours per night than recommended. An association in the crude model (crude OR 1.82; CI 95%: 1.29-2.56), in model 2 adjusted for cola drinks (OR 1.83; CI 95%: 1.30-2.59) and in model 3 adjusted for dinner, cola drink and caffeine beverage consumption and nocturia (OR 1.85; CI 95%: 1.30-2.62) was observed. It was also noticed that exercising was a protective factor against overweight and obesity; however, periodic limb movement during sleep was a risk factor.
This study showed an association between fewer hours of sleep and an increase in the risk of overweight/obesity.
主要在成年人中进行的研究表明，睡眠量与肥胖之间存在关联。
确定智利学童在工作日和周末夜间睡眠不足与饮食习惯、身体活动及营养状况之间是否存在关联。
研究对象、材料与方法：横断面研究。对6至11岁的学生进行人体测量评估；让家长使用匹兹堡睡眠质量指数（PSQI）来衡量其子女的睡眠质量；询问他们有关饮食习惯和身体活动的情况。
对圣地亚哥公立学校的1810名男女学童进行了评估。在这些学童中，49.9%的人每晚睡眠时间少于建议时长。在未调整模型（未调整比值比1.82；95%置信区间：1.29 - 2.56）、在调整了可乐饮料的模型2（比值比1.83；95%置信区间：1.30 - 2.59）以及在调整了晚餐、可乐饮料、咖啡因饮料消费和夜尿症的模型3（比值比1.85；95%置信区间：1.30 - 2.62）中均观察到了这种关联。还注意到，锻炼是预防超重和肥胖的保护因素；然而，睡眠期间周期性肢体运动是一个风险因素。
本研究表明睡眠时间减少与超重/肥胖风险增加之间存在关联。
