The purpose of this study was to compare the anthropometric and sleep-wake rhythm characteristics of schoolchildren that attend school in morning and afternoon school shifts.
We recruited 18 481 individuals (females: 56.4%) aged 11 to 18 years old with an average age of 14.4 ± 1.7 years old. In total, 812 (4.2%) questionnaires were incomplete. The self-reported height and weight were used to assess the sex- and age-corrected body mass index of the participants. The Munich ChronoType Questionnaire was used to assess the chronotype, social jetlag, and sleep duration of the participants.
In total, 12.6% of the participants were affected by overweight or obesity. The overweight and obesity incidence rate was higher among the students studying in the afternoon (odd ratio [95%CI]: 1.33 [1.16-1.52]). The afternoon school shift had a negative impact on the anthropometric indicators only in the 11-14-year-olds (1.29 [1.11-1.50]) and girls (1.26 [1.04-1.54]) with an early (1.27 [1.03-1.56]) and intermediate (1.30 [1.07-1.58]) chronotype.
The data obtained indicated that the afternoon school shift is not ideal, especially for female children and adolescents under 15 years old with an early and intermediate chronotype.
本研究旨在比较上午和下午上学的学童的人体测量和睡眠-觉醒节律特征。
我们招募了18481名年龄在11至18岁之间的个体（女性：56.4%），平均年龄为14.4±1.7岁。总共有812份（4.2%）问卷不完整。使用自我报告的身高和体重来评估参与者经性别和年龄校正的体重指数。使用慕尼黑时间类型问卷来评估参与者的时间类型、社会时差和睡眠时间。
共有12.6%的参与者受到超重或肥胖的影响。下午上学的学生中超重和肥胖的发生率更高（比值比[95%置信区间]：1.33[1.16-1.52]）。下午上学仅对11至14岁（1.29[1.11-1.50]）以及具有早起型（1.27[1.03-1.56]）和中间型（1.30[1.07-1.58]）时间类型的女孩（1.26[1.04-1.54]）的人体测量指标有负面影响。
所获得的数据表明，下午上学不理想，尤其是对于15岁以下具有早起型和中间型时间类型的女童和青少年。
