Abstract
Purpose: This study investigates the association between weekend catch-up sleep (CUS) and overweight/obesity in Korean adolescents, focusing on weekday sleep sufficiency.
Methods: A nationwide cross-sectional study was conducted among 12,434 high school students in South Korea. Sleep patterns including total sleep duration and weekend CUS were assessed using self-reported questionnaires. Body mass index (BMI) was calculated and categorized into overweight/obese and normal weight groups based on age- and sex-adjusted Z-scores. Logistic and linear regression models were used to assess the associations between sleep variables and overweight/obesity.
Results: Students with 3 or more h of CUS had lower odds of being overweight/obesity (odds ratio = 0.67, 95% confidence interval: 0.57-0.80) compared to those with non-CUS. This protective effect remained significant in the subgroup with perceived insufficient weekday sleep. Furthermore, students with 3 or more h of CUS had significantly lower BMI z-scores (β = -0.18, p < 0.001), an association that was also observed in those with perceived insufficient sleep (β = -0.16, p = 0.003). The analysis showed a dose-dependent pattern, with greater weekend CUS being associated with a stepwise reduction in BMI z-scores.
Conclusions: Weekend CUS may serve as an important compensatory mechanism for adolescents to reduce the risk of being overweight or obese. However, no additional benefits of CUS were observed in adolescents with sufficient sleep quality.
期刊介绍：
The journal Sleep and Breathing aims to reflect the state of the art in the international science and practice of sleep medicine. The journal is based on the recognition that management of sleep disorders requires a multi-disciplinary approach and diverse perspectives. The initial focus of Sleep and Breathing is on timely and original studies that collect, intervene, or otherwise inform all clinicians and scientists in medicine, dentistry and oral surgery, otolaryngology, and epidemiology on the management of the upper airway during sleep.
Furthermore, Sleep and Breathing endeavors to bring readers cutting edge information about all evolving aspects of common sleep disorders or disruptions, such as insomnia and shift work. The journal includes not only patient studies, but also studies that emphasize the principles of physiology and pathophysiology or illustrate potentially novel approaches to diagnosis and treatment. In addition, the journal features articles that describe patient-oriented and cost-benefit health outcomes research. Thus, with peer review by an international Editorial Board and prompt English-language publication, Sleep and Breathing provides rapid dissemination of clinical and clinically related scientific information. But it also does more: it is dedicated to making the most important developments in sleep disordered breathing easily accessible to clinicians who are treating sleep apnea by presenting well-chosen, well-written, and highly organized information that is useful for patient care.
