Variations in circadian rhythmicity and students' gender-related psychological conditions during the COVID-19 lockdown

In the face of the COVID-19 pandemic experienced around the world, new student lifestyles have had an impact on their daily behavior. The purpose of this study was to examine post-traumatic stress associated with the initial COVID-19 crisis in students (N = 280) with a mean age of 13 +/- 1.70 and to determine the relationship between their reported daily behaviors in terms of their gender. The study was conducted primarily in Casablanca and Marrakech, the two cities most affected by the pandemic at the time of the study in Morocco in May 2020. Our sample consists of 133 high school students and 147 middle school students, 83.6% of whom are females. Students were asked to answer questions based on an Activity Biorhythm Questionnaire, the Post-Traumatic Stress Scale (Weathers et al., 1993), the Hamilton Scale (Hamilton, 1960), the Worry Domains Questionnaire (Tallis, Eyzenck, Mathews, 1992), and the Visual Analog Scale of Moods (VASM) (Stern et al., 1997). The results obtained confirm that there is a significant relationship between the circadian rhythm of some variables and gender in some activities such as academic study (p < 0.05) and TV and Internet use (p < 0.05) and was highly significant for physical activity (p = 0.001), while others are not significant in relation to other schedules of the same variables or in relation to others. Likewise, for the psychological conditions, significant relationships with mood states and depressive tendencies were confirmed. In lockdown, the students' daily lives underwent changes in circadian rhythm and lifestyle. Therefore, it is necessary to treat their current psychological problems and avoid future complications.

Effect of COVID-19 lockdown on sleep behavior and screen exposure time: An observational study among Indian school children

Lockdown is an important measure that has been globally adopted to reduce the spread of the contagious disease caused by SARS CoV-2. The imposed schedule and confinement led to extensive use of digital media and rise in sedentary activity drastically. The escalated duration of screen exposure causes disruption in sleep behavior. An online survey was conducted to comprehend the effect of lockdown on sleep behavior and screen exposure time on school children. Screen exposure time involved with various electronic gadgets was also analyzed. It was observed that the social jet lag and sleep debt were significantly less during lockdown than before it. Inertia during lockdown significantly increased. The difference between screen exposure time on weekdays before lockdown and weekends during lockdown was identified to be the highest. Three clusters based on sleep behavior and duration of screen time were identified of which Cluster 2 revealed simultaneous existence of high sleep duration and screen time. These baseline data on sleep parameters and duration of exposure to the screen will help us in devising approaches to mitigate the evident disruption this unprecedented phase has brought about.

Reliability and validity of the Arabic version of the biological rhythms interview of assessment in neuropsychiatry.

BACKGROUND: Disruptions in biological rhythm (BR) are considered a factor in the spread of many chronic diseases such as hypertension, diabetes, and depression. It has been shown that imbalance in BR disrupts the body's physiological timings; therefore, it is essential to have a tool for BR evaluation. METHODS: A cross-sectional study was conducted on a sample of 403 Jordanian participants (200 depressed people and 203 control groups). Classical test theory (CTT) was used to evaluate the psychometric properties of the Arabic version of BRIAN. We aimed to validate the Arabic version of Biological Rhythms Interview Assessment in Neuropsychiatry (BRIAN) by investigating its internal consistency and validity, assessing its factor structure, and exploring its relationships with depression and sleep disorders. RESULTS: The internal consistency (α) was 0.91. The concurrent validity was supported by the severity of depression and sleep disorders (r = 0.87, r = 0.83, p < 0.001). The BRIAN's ability to differentiate between depressed people and the control group supported its discriminant validity (t = 21.2, p = 0.001). With a sensitivity of 75 and a specificity of 95.57, BRIAN revealed good accuracy in distinguishing between depressed and non-depressed persons at cutoff 44. The exploratory factor analysis (EFA) and the confirmatory factor analysis (CFA) analyses supported its proposed three-factor solutions. CONCLUSIONS: The results demonstrated that the BRIAN-A has acceptable validity in detecting BR and could be useful in examining the impact of circadian disturbance on the Arabic population.

Effect of the COVID-19 Lockdown on Asthma Biological Rhythms.

Asthma has a striking temporal character, in which time-of-day, patient age, and season each influence disease activity. The extent to which rhythms in asthma activity reflect exposure to specific disease triggers remains unclear. In this study, we examined how virus mitigation strategies enacted during the COVID-19 pandemic ("lockdown measures") affected rhythms in asthma clinical activity in children. To this end, we retrospectively analyzed asthma clinical presentations in children aged <18 years to our regional academic medical center, comparing 4 years of medical records prior to COVID-19 lockdown measures with the 12 months immediately after the institution of such measures. We correlated these data to positive viral test results, febrile seizures, and allergic clinical surrogates (allergic reaction visits and Emergency Department [ED] antihistamine prescriptions, respectively) over the same time frame. In the 12 months following the institution of the COVID-19 lockdown, positivity rates for common respiratory viruses dropped by 70.2% and ED visits for asthma among children dropped by 62% compared to pre-COVID years. Lockdown suppressed seasonal variation in positive viral tests and asthma ED visits, while diurnal rhythms in asthma visits were unchanged. Asthma seasonality correlated most strongly with rhinovirus positivity both before and after the institution of COVID lockdown measures. Altogether, our data support a causal role for viruses in driving seasonal variability in asthma exacerbations in children.
