“…Social jetlag represents a mismatch between socially driven behavioral schedules and the circadian system leading to circadian misalignment. By sleeping at irregular times, social jetlag disturbs the optimal alignment of behaviors such as sleep, eating, and physical activity relative to the circadian system and the related processes it controls 65,66 . For instance, such circadian misalignment caused by social jetlag may disrupt the hypothalamic–pituitary–adrenal (HPA) axis and glycemic and metabolic changes 65,67 .…”

SummarySocial jetlag, the weekly variation in sleep timing, is proposed to contribute to increased obesity risk, potentially because of the misalignment of behavioral cycles relative to the endogenous circadian timing system. This systematic review and meta‐analysis aim to determine the association between social jetlag and adiposity‐related measures using observational studies. We reviewed 477 references, of which 43 studies met inclusion criteria with a total sample size of 231,648. There was a positive association between social jetlag and body mass index (correlation coefficient [r]: 0.12; 95%CI, 0.07, 0.17; P < 0.001; I2 = 94.99%), fat mass (r: 0.10; 95%CI, 0.05, 0.15; P < 0.001; I2 = 0.00%), fat mass index (fat mass divided by height in meter squared, β: 0.14 kg/m2; 95%CI, 0.05, 0.23; P < 0.001; I2 = 56.50%), percent of body fat (r: 0.37; 95%CI, 0.33, 0.41; P < 0.001; I2 = 96.17%), waist circumference (r: 0.15; 95%CI, 0.06, 0.24; P = 0.001; I2 = 90.83%), and the risk of having overweight/obesity (odds ratio: 1.20; 95%CI, 1.02, 1.140; P = 0.039; I2 = 98.25%). Social jetlag is positively and consistently associated with multiple obesity‐related anthropometric measures. Further studies are needed to test causality, underlying mechanisms, and whether obesity interventions based on increasing regularity of the sleep/wake cycle can aid in the battle against the obesity pandemic.

Objectives The coronavirus disease (COVID-19) had a major impact on sleep and training behavior in adolescent athletes. A crucial sleep parameter is midsleep time, which illustrates the midpoint between sleep onset and offset. The aim of this investigation was to examine the impact of chronotype, age, sex, pandemic phase, weekend, and training habits on midsleep time. The sample consisted of German elite adolescent basketball athletes (N = 91, 15.75 ± 1.15 years, female = 39.46%). Method Data were collected through a 10-day subjective monitoring program during three different pandemic phases, with more severe restrictions in phase 1. In total, 1146 measurement points were analyzed. A linear mixed model approach was used for the evaluation. Results A negative linear association between chronotype and midsleep time was revealed. A negative effect was identified for phases 2 and 3. The weekend parameter showed a positive effect, which may illustrate the occurrence of social jetlag. The main finding of this investigation is that a morning chronotype distribution was associated with earlier midsleep timing throughout the entire survey period. Conclusion The results acknowledge that chronotype is one of the main influencing parameters for midsleep time. The study represents a useful contribution to the research of chronotype and sleep behavior in athletes, with a focus on the major impact of the COVID-19 pandemic.
