Summary: This study found that both short and long sleep durations are associated with demographic, medication use, personal habits, and chronic diseases. The impact of hypnotic drug use on sleep duration was also considered. The results showed that short sleep duration was significantly associated with age, BMI, physical activity, and depression, while long sleep duration was associated with female sex, opium consumption, and history of MI. Stratified analysis for hypnotic drug use revealed additional associations with education, physical activity, opium consumption, and thyroid dysfunction.

Summary: This study found an association between short sleep duration during early pregnancy and GDM, with short sleepers having a higher risk of GDM compared to normal sleepers. It is suggested that pregnant women with insufficient sleep should be given more attention to control the development of GDM.

Summary: This study aimed to investigate the association between sleep duration trajectories and cognitive performance in preschool-aged Chinese children. The results showed that children with a short total sleep duration trajectory had poorer cognitive performance on the Visual Spatial Index and an increased risk of a low full-scale intelligence quotient. Therefore, medium total sleep duration, adequate sleep at nighttime, and appropriate sleep in the daytime seem to be more beneficial for children's cognitive development.

Summary: A bidirectional relationship was found between sleep quality and aggressive behavior among early adolescents, while sleep duration did not predict aggressive behavior. This suggests that improving sleep quality should be the primary focus for managing aggressive behavior.

Summary: The study found a high prevalence of overweight/obesity and hypertension in rural South African youth, with over half of the adolescents at risk of developing cardiovascular disease. There is a significant association between cardiometabolic risk factors and pulse wave velocity. Early detection and preventive strategies are urgently needed to prevent the progression of vascular damage and manifestation of cardiovascular disease in underprivileged young people in rural Africa.

Summary: This study used objective sleep characteristics to identify sleep clusters in adolescents and examined their associations with cardiometabolic health. Five sleep clusters were identified, and the study found that the prolonged sleep latency cluster was associated with higher fat mass index (FMI), while the sleep irregularity and variability cluster was specifically linked to elevated triglycerides in male individuals.

Summary: This study aimed to establish the optimal cutoffs of sleep timing and duration to assess various cardiovascular disease risk factors. The findings showed that bedtime between 9:00 PM to 0:30 AM for men and 10:00 PM to 11:00 PM for women is appropriate. The cutoff range was slightly earlier for participants aged 65 years and older. Early MSFsc between 12:00 AM to 3:00 AM and sleep durations around 6 hours were associated with the optimal cutoffs for assessing CVD risk factors.

Summary: The study found that breastfeeding, having a bedtime after midnight, and being employed were associated with shorter sleep duration, while multiparity, being unmarried, being employed, breastfeeding, bedsharing, and responding to infant awakenings by getting up immediately were significant determinants of sleeping less than 7 hours per night. Bedsharing was the only variable identified from the multiple regression model that associated with poorer sleep efficiency.

Despite ongoing gaps in income and education levels, the reduction in child mortality and socioeconomic inequalities is largely attributed to government policies and programs that prioritize equity.

Summary: This study explored the differences between preterm and term-born individuals in birth size and adult height, weight, and blood pressure in a Brazilian birth cohort. Preterm participants had lower birth size and remained shorter in adulthood for males, but not for females. At 22 years, females born preterm had lower blood pressure compared to term-born females. These differences were not observed in males.

Summary: Compared to full-term infants, early-term infants have a higher risk of shorter exclusive breastfeeding duration and lower prevalence of any breastfeeding at 12 months. The study found that there was no difference in the prevalence of exclusive breastfeeding at 3 months between early-term infants and full-term infants, but early-term infants had a lower prevalence of any breastfeeding at 12 months. These findings indicate the increased risk of early weaning among preterm infants.

Summary: This study aimed to investigate the association between physical activity in early childhood (1-4 years) and chronic stress. The results showed no clear association between early physical activity and chronic stress at age 4. However, higher levels of physical activity throughout early childhood may have a positive impact on chronic stress.

Summary: This study examines decision-making impairments in individuals with central disorders of hypersomnolence (CDH), specifically narcolepsy type 1 (NT1). The results suggest that both NT1 and other CDH patients have decreased learning abilities to avoid losses, which is associated with alterations in vigilance. The study provides new insights into the nature of decision-making impairments in CDH and suggests the potential for minimizing these alterations by restoring adequate vigilance.

Using data from a randomized clinical trial, the model helps identify patterns of treatment progression and their association with baseline insomnia severity. The model holds potential for further research on various CBT-I processes that are currently not fully understood.

Summary: In recent years, there has been a growing interest in the influence of gut microbiota on sleep physiology. The gut microbiota affects the central nervous system and circadian rhythms, and can be associated with sleep disorders. This study observed the gut microbiota composition of patients with different types of narcolepsy and idiopathic hypersomnia, and found changes in beta diversity in these patient groups compared to healthy controls. However, after adjusting for confounding factors, the differences were no longer statistically significant. The study suggests that using metabolomics and proteomics approaches to study the role of microbiota in sleep disorders may be beneficial.

Summary: This study aims to investigate pulmonary arterial hypertension (PAH) phenotypes and their prognostic implications by clustering overnight cardiorespiratory signals in PAH patients. Three distinct clusters were identified, with patients in Cluster 3 exhibiting worse clinical outcomes. The presence of nocturnal hypoxemia and obstructive sleep apnea (OSA) in PAH patients was associated with increased risk of clinical worsening. Tailored management strategies addressing both PAH and nocturnal hypoxemia may improve clinical outcomes.

Summary: This study investigated the long-term impact of dopamine agonist treatment on altered central sensory processing in restless legs syndrome (RLS) patients. The results showed that dopamine agonist treatment effectively reduced RLS symptoms but did not reverse the altered central sensory processing observed on testing. These findings suggest that RLS pathophysiology is multifactorial and not solely driven by dopaminergic dysfunction.
