确定超重和肥胖儿童的饮食、久坐和体育活动行为在工作日和周末是否不同。81名6-9岁的超重或肥胖儿童参加了体重管理计划，他们在两个工作日和一个周末完成了为期3天的食物日记和为期3天的前一天身体活动回忆（PDPAR）。所有数据均在干预实施前的基线时获得。儿童在周末从脂肪（t = 2.15，p = 0.04）中消耗的卡路里百分比更高，水果（t = 6.83，p <0.001），蔬菜（t = 2.91，p= 0.002），非营养密集（NND）零食（t = 5.58，p <0.001）和含糖饮料（t = 2.91，p = 0.005）较少。与工作日相比，孩子们在周末看更多的电视（t= 5.25，p <0.001），消耗更多的能量（t = 4.37，p <0.001），并花费更大比例的时间进行中度到剧烈的体力活动（p <0.001）。研究结果表明，儿童在周末和工作日的饮食和活动习惯存在一些差异。他们还建议，在工作日和周末分别关注食物摄入量和活动习惯的差异可能有助于确定高风险时期，这可以通过有效的干预方法进行修改。NCT 00259324、NCT 00200265。
To determine whether eating, sedentary, and physical activity behaviors differ on weekdays and weekends in a sample of children who are overweight and obese. Eighty-one children 6–9 years old who were overweight or obese and enrolled in a weight management program completed 3-day food diaries and 3-day Previous Day Physical Activity Recalls (PDPARs) for two weekdays and one weekend day. All data were obtained at baseline prior to intervention delivery. Children consumed a greater percentage of calories from fat (t = 2.15, p = .04) and fewer fruits (t = 6.83, p < .001), vegetables (t = 2.91, p=.002), non-nutrient dense (NND) snack foods (t = 5.58, p < .001), and sweetened drinks (t = 2.91, p = .005) on weekends. Children watched more television (t= 5.25, p < .001), expended more energy (t = 4.37, p < .001), and spent a greater percentage of time in moderate-to-vigorous physical activity (p < .001) on weekends compared to weekdays. Findings demonstrate a number of differences in children’s eating and activity habits on weekends and weekdays. They also suggest that attending to differences in food intake and activity habits separately on weekdays and weekends may help to identify periods of high risk, which could be modified with effective intervention approaches.
