Observational study to understand the effect of timing and regularity on sleep metrics and cardiorespiratory parameters using data from a smart bed
This study highlights how sleep regularity and chronotype influence sleep quality and cardiorespiratory metrics. Irrespective of chronotype, sleep regularity demonstrated a substantial effect. Further research is necessary to confirm these findings.PMID:38153128 | DOI:10.1080/07420528.2023.2298267 (Source: Chronobiology International)

Lifestyle factors, dietary patterns, and social determinants of social and eating jetlag: A cross-sectional survey
Chronobiol Int. 2023 Dec 28:1-11. doi: 10.1080/07420528.2023.2298700. Online ahead of print.ABSTRACTSocial jetlag (SJL) and, more recently, eating jetlag have been linked with an increased risk of non-communicable diseases. Here we aim to investigate lifestyle factors (diet, eating behavior, smoking, perceived stress, time spent sedentary/day) and social determinants (education level, employment status, and place of residence) associated with SJL corrected for sleep duration (SJLsc) and eating jetlag. Self-declared data on age, gender, lifestyle, and eating behavior were collected online from March 2021 to February 2022 of...

Vaccination time does not influence total anti-SARS-CoV-2 antibodies response
Chronobiol Int. 2023 Dec 26:1-2. doi: 10.1080/07420528.2023.2298264. Online ahead of print.ABSTRACTWe measured total anti-SARS-CoV-2 receptor-biding domain (RBD) antibodies in 249 healthcare workers (mean age: 44 ± 13 years; 151 women), who received the first dose of mRNA-based Comirnaty COVID-19 vaccine at different times of the day. Compared with the reference vaccination time point (i.e. <10:00h), vaccine injection at the following times of day elicited a comparable response (all p > 0.05). Under our experimental conditions, we can therefore exclude a possible influence of the timing of primary mRNA-based COVID-1...

Effects of a simulated maritime shift schedule on vigilance, sleep, and sleepiness
Chronobiol Int. 2023 Dec 26:1-11. doi: 10.1080/07420528.2023.2298279. Online ahead of print.ABSTRACTShift work is associated with circadian misalignment, which causes sleep loss, impairs performance, and increases the risk of accidents. Shorter, more frequently shifting watch schedules, widely used in industries such as maritime operation, defense, and mining, may mitigate these risks by reducing shift length and providing sleep opportunities for all workers across the biological night. However, the effects of frequently shifting work on sleep and performance still need to be clarified. The current study investigated the v...

The effect of time of day on Special Judo Fitness Test in active judokas: Evaluation in terms of chronotype
In conclusion, coaches and exercise experts should consider judo athletes' chronotype when planning special training programs to improve judo-specific anaerobic capacity. Furthermore, to minimize the impact of time of day and chronotype on athletes' performance in competitions, it is recommended that MT athletes develop their judo-specific anaerobic capacity in the evening hours, when their performance is lower, while ET athletes should do so in the morning hours when their performance is lower via randori training.PMID:38124619 | DOI:10.1080/07420528.2023.2276196 (Source: Chronobiology International)

Relationship between mid-sleep time and depression, health-related quality of life, and sleep deprivation in the 2018 Korea Community Health Survey
This study included 173 284 adults aged ≥ 19 years who participated in the 2018 Korea Community Health Survey. The Patient Health Questionnaire-9 for depression, EuroQol-5 dimension for health-related quality of life, and the Pittsburgh Sleep Quality Index for MST, daytime sleepiness, and sleep quality were used. Regression and logistic regression analysis was used for complex sample analysis. The results showed that individuals with later MST had a higher risk of depression, poor quality of life, poor sleep quality, and excessive daytime sleepiness than intermediate-type individuals, whereas earlier MST was associated w...
