Life on Holidays: Fitness lost, fatness regained?

最近有证据表明，孩子们在学期中变得更瘦、更健康，但在暑假期间变得更胖、更不健康。这可能是因为活动和饮食的不同：在节假日，孩子们可能吃得更多，活动更少，屏幕上的时间更多。我们建议在三个学年跟踪9-11岁儿童的时间使用、饮食、健康和肥胖情况。如果这种模式得到证实，我们应该更多地关注家庭环境，或者或许鼓励夏令营。

There’s recent evidence that children get leaner and fitter during the school term, but become fatter and less fit over the summer holidays. This may be because of differences in activity and diet: on holidays, children may eat more, be less active and have more screen time. We propose to track the time use, diet, fitness and fatness of 9-11 year old children across three school years. If the pattern is confirmed, we should focus more on the home environment, or perhaps encourage summer camps.
