Abstract
Summary: Objective: 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. Methods: 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. Results: 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. Conclusion: 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.
