Summary: This study investigated the associations between social jetlag (SJL), dietary behavior, physical activity, and weight status in Chinese youth. The findings showed that adolescents with SJL may consume more unhealthy foods, engage in less physical activity, and have higher BMIs. Moreover, experiencing more than 2 hours of SJL significantly increased the risk of overweight or obesity in adolescents.

Summary: The travel restrictions and work from home orders imposed in Ireland in March 2020 had a significant impact on sleep timing and quality. Sleep start and end times were shifted to later, as well as the time of midsleep. Sleep duration was longer on work days, while shorter on free days, and there was a reduction in social jetlag during the restrictions. Individuals who worked from home had longer sleep duration on work days compared to essential workers who continued to attend their normal place of work.

Summary: This study examined the mediating effect of chronotype and social jetlag in the relationship between screen use before sleep and emotional problems. The results showed that adolescents who reported screen use before sleep exhibited later chronotype and greater social jetlag, which in turn were associated with higher levels of emotional problems. The serial indirect effect of chronotype and social jetlag explained 6.2%-16.7% of the total effect of screen use before sleep on emotional problems.

Summary: This study examined the distinct roles of chronotype and trait self-control in predicting sleep quality and found that trait self-control predicts sleep quality directly and indirectly through pre-sleep stress management and maintaining a restful sleep environment, whereas chronotype predicts sleep quality indirectly through pre-sleep stress management and bedtime media use. The study also showed that bedtime media use and irregular sleep timing are related to poor sleep quality in evening types, while environmental interference is more relevant to poor sleep quality in individuals low in self-control.

Summary: The aim of this study was to summarize findings from studies conducted in adolescents examining both sleep variability and regularity in relation to obesity and cardiometabolic health. Results showed that increased sleep variability and irregularity are associated with obesity, decreased physical activity, dysregulated eating and inadequate diet, metabolic dysfunction, impaired cardiac autonomic balance, and elevated blood pressure in adolescents. Future studies should focus on the underlying behavioral and biological mechanisms in the causal pathway between day-to-day deviations in the amount and timing of sleep and obesity.

Summary: The objective of this study was to evaluate the associations between preconception sleep characteristics and shift work with fecundability and live birth. The results showed that there does not appear to be a strong association between sleep characteristics, fecundability, and live birth. Although there may be weak and imprecise associations with some sleep characteristics, our findings should be evaluated in larger cohorts of women with extremes of sleep characteristics.

Summary: This study described the prevalence of depressive symptoms among Chinese college students and found a relationship between sleep and circadian rhythm disruption indicators and depressive symptoms. Evening types and short sleep duration were significantly associated with depression. The findings suggest that depressive symptoms are more severe when multiple circadian rhythm indicators are out of whack.

Summary: Younger adults naturally have a tendency to sleep and wake up later, which conflicts with early morning responsibilities. The COVID-19 pandemic and remote learning allowed for more flexibility in sleep timing and reduced differences in sleep patterns between school days and weekends. A study comparing three groups of students before, during, and after the shutdown found that the timing and duration of sleep remained consistent during the shutdown period and there was no increase in irregular sleep patterns.

Summary: This pilot study explored the associations between OSA severity and metabolites in obese women with GDM. Although there were no significant differences in metabolomics profiles between those with and without OSA, a targeted approach found that some metabolites such as oestradiols, lysophospholipids, and fatty acids were significantly associated with OSA severity. These metabolites may play a role in the pathogenesis of OSA in pregnant women with GDM.

Summary: Sleep duration was found to be associated with changes in gut microbiota composition, with shorter and longer sleepers showing higher levels of certain taxonomic features. These findings suggest a potential link between disrupted sleep patterns and gut microbiota composition, which may have implications for chronic inflammation associated diseases. Further research is needed to confirm these results and explore the underlying mechanisms.

Summary: Prediabetes is prevalent among people living with HIV, and insufficient and irregular sleep may impact glucose metabolism. This study found no significant differences in sleep characteristics between PLWH with normoglycemia and prediabetes, and demonstrated that a six-month intensive lifestyle intervention program was effective in reducing body weight and waist circumference in prediabetic individuals. Furthermore, an increase in sleep variability was associated with higher 2-h plasma glucose levels, independent of BMI and physical activity changes.
