Sleep problems during adolescence affect current and subsequent mental health and are associated with experiences of psychotic symptoms. Recent studies have suggested that short sleep duration increases the risk of experiencing psychotic symptoms in the general adolescent population; however, whether long sleep duration is associated with an increased risk of psychotic symptoms in adolescence remains unclear. The present study aimed to examine the relationships between long sleep duration, short sleep duration, and the risk of experiencing psychotic symptoms in adolescence. Cross-sectional survey data from 15,786 junior and senior high school students (12- to 15-year-olds and 15- to 18-year-olds, respectively) in Japan were collected and analyzed using logistic regression analysis after controlling for covariates, including depressive symptoms. Long sleep duration was associated with a 1.6- to 2.8-fold increased risk of psychotic symptoms in male but not in female adolescents. Short sleep duration was also related with a 1.6- to 2.9-fold increased risk of experiencing psychotic symptoms, except for 15- to 18-year-old female adolescents. The present study suggested that adolescents with long and short sleep duration should be assessed for their risk of experiencing psychotic symptoms regardless of concurrent depressive symptoms.

Sleep Patterns Among Athletes and Non-Athletes During Ramadan intermittent fasting: Systematic Review, Meta-Analysis and Meta-Regression.
Ann Ig

Multidisciplinary Laboratory in Education Sciences and Training Engineering (LMSEIF). Sport Science Assessment and Physical Activity Didactic. Normal Higher School (ENS-C), University Hassan II, Casablanca, Morocco.
Background: Ramadan fasting is a religious observance practiced regularly by Muslims and may have an effect on sleep quality, especially for athletes. Our systematic review with meta-analysis aims to identify the effect of Ramadan observance on the sleep patterns of athletes and non-athletes during Ramadan fasting over the teen years (2014-2024).
Study Design: A systematic search of Scopus, Web of Science, and Pubmed, was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses.
Hypotensive Episodes Identified on 24-Hour Ambulatory Blood Pressure and Impaired Cognitive Function: Insights From the SPRINT Study.
Hypertension

Department of Epidemiology, Harvard T.H. Chan School of Public Health, Boston, MA (W.Z., D.H., M.A.M., Y.M.).
Background: Hypotensive episodes detected by 24-hour ambulatory blood pressure (BP) monitoring capture daily cumulative hypotensive stress and could be clinically relevant to cognitive impairment, but this relationship remains unclear.
Methods: We included participants from the Systolic Blood Pressure Intervention Trial (receiving intensive or standard BP treatment) who had 24-hour ambulatory BP monitoring measured near the 27-month visit and subsequent biannual cognitive assessments. We evaluated the associations of hypotensive episodes (defined as systolic BP drops of ≥20 mm Hg between 2 consecutive measurements that reached <100 mm Hg) and hypotensive duration (cumulative time of systolic BP <100 mm Hg) with subsequent cognitive function using adjusted linear mixed models.
U-shaped association between sleep duration and frailty in Chinese older adults: a cross-sectional study.
Front Public Health
January 2025
School of Athletic Performance, Shanghai University of Sport, Shanghai, China.
Objective: As the population ages, understanding the association between sleep patterns and physical frailty in older adults is crucial for formulating effective health interventions. This study aimed to explore the relationship among nap time, nighttime sleep duration, and physical frailty in older Chinese individuals; establish recommended sleep times; and provide a scientific and reasonable basis for the prevention and management of frailty in older adults.
Methods: On the basis of the 2020 China Health and Retirement Longitudinal Study database, demographic information, health data, and lifestyle information of the research subjects were obtained.
Threshold effects of sleep duration and cognitive function in older adults with BMI ≥ 25 kg/m.

Department of General Medicine, Huashan Hospital, Fudan University, Shanghai, China.
Background: It has been demonstrated that older adults' cognitive capacities can be improved with sleep duration. However, the relationship between overweight, obesity, and cognitive decline remains a subject of debate. The impact of sleep duration on cognitive performance in seniors with a body mass index (BMI) ≥ 25 kg/m is largely unknown.
