Beyond mechanical causes, central sensitization (CS) has been recognized as a key mechanism in chronic pain. This study investigated the relationship between chronotype (morning, intermediate, evening) and CS severity in NSLBP patients, and whether chronotype is associated with pain intensity and disability. A total of 131 patients (aged 18-65) were assessed using the Morningness-Eveningness Questionnaire (MEQ), Central Sensitization Inventory (CSI), Pain Catastrophizing Scale (PCS), Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), Visual Analogue Scale (VAS), and Roland-Morris Disability Questionnaire (RMDQ). Three-way ANCOVA (controlling for age, gender, and occupation) revealed that evening-type individuals had significantly higher CSI, PCS, BDI, PSQI, and RMDQ scores (all p < 0.05). Hierarchical regression analysis showed that evening chronotype (β = 0.193, p = 0.004), pain catastrophizing (β = 0.508, p < 0.001), and depressive symptoms (β = 0.435, p < 0.001) were independent predictors of CS severity. These findings suggest that eveningness is associated with more severe central sensitization and adverse psychosocial outcomes in NSLBP. Chronotype may play a role in pain modulation and should be considered in assessment and management strategies.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"913-920"},"PeriodicalIF":2.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144246677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As previous studies have reported that young adults are more susceptible to sleep deprivation, so the goal of the present study was to investigate the prevalence of chronotype, and its associations between circadian preferences, sleep and its physiological implications, cognitive performances and metabolic profiles among university-level students in the north-eastern parts of the Indian subcontinent. Majority of the students fall in intermediate chronotype in our study with the evening chronotypes having poor sleep quality, leading to low cognitive function that in turn causes periods of anxiety and stress which was reflected in salivary cortisol levels. The evening chronotypes also exhibited lower nocturnal melatonin levels compared to morning types and had difficulty in falling to sleep with elevated oral temperatures. Elevated BMI status and frequencies of fast-food intake were also high in evening chronotypes, which may increase the chances of obesity in them and also prone to hyperglycemia as indicated by higher fasting blood sugar and salivary amylase levels. The metabolic profiles were also altered in late chronotypes as evidenced by low thyroid hormone profiles and higher triglyceride levels. Our study reports intermediate chronotypes along with evening types are at the risk of developing sleep deprived disorders in the future, and it is important that researchers should develop tailored sleep interventions that consider demographic, psychological, and socio-behavioral factors contributing to poor sleep quality, excessive daytime sleepiness, and short sleep duration among students.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"840-863"},"PeriodicalIF":2.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A sample of 306 children aged 1.5 to 5 years was recruited through the Health and Social Welfare Division, A City. Caregivers reported sleep patterns using daily activity logs, and behavioral problems were assessed using the Child Behavior Checklist 1½-5. Main sleep measures included total sleep time and weekly standard deviations of bedtime, wake time, and total sleep time, reflecting sleep IIV. Logistic regression analyses adjusted for confounding factors (e.g. child age, birth order, maternal age at birth) indicated that higher IIV in bedtime was significantly associated with increased internalizing problems, while greater IIV in total sleep time was linked to externalizing problems. Both indicators of IIV were also associated with overall behavioral problems, independent of average nighttime sleep duration. These findings underscore the relevance of consistent sleep-wake rhythms for emotional and behavioral stability in early childhood and indicate that addressing sleep IIV could support efforts to foster healthier behavioral development.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"905-912"},"PeriodicalIF":2.2,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144224546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An important and widely used questionnaire for measuring chronotype is the Munich Chronotype Questionnaire for Shift workers (MCTQShift); however, it has neither been validated nor is it available in Norwegian or any other Scandinavian language. Therefore, we translated the MCTQShift into Norwegian and assessed its validity against subjective and objective sleep measures. We adhered to established methodological guidelines to translate the questionnaire. The final Norwegian version was administered to 60 workers (85% responders) on a three-shift schedule (21.7% women, median age 28 y) at an industrial plant. Sleep duration and mid-sleep from the MCTQShift were compared with sleep diary and a multisensory sleep tracker (the Oura ring). Construct and criterion validity were evaluated. Sleep duration measured by the MCTQShift was highly correlated (r > 0.6) with sleep duration calculated from both the Oura ring and sleep diaries after morning shifts. On free days, the MCTQShift correlated moderately with the sleep diary but weakly with the Oura ring. Mid-sleep correlations from MCTQShift compared to the Oura ring data were high (r > 0.7) for sleep periods after morning and night shifts, and moderate (r = 0.5) sleep periods between free days following morning shift. Bland-Altman analyses indicated that the MCTQShift overestimated sleep duration and underestimated mid-sleep, with the largest discrepancies on free days after morning shifts. Night shifts showed the most pronounced outliers. The Norwegian MCTQShift shows promising validity for assessing sleep habits in shift workers, particularly on workdays. However, reduced accuracy on free days after morning shifts suggests limitations in capturing sleep patterns across all shift types.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-12"},"PeriodicalIF":2.2,"publicationDate":"2025-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144526574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 421 nurses were selected from 10 Grade secondary public hospitals in Shanghai, China. The 12-item General Health Questionnaire (GHQ-12) was used to assess mental health status. Additionally, psychological flexibility and well-being were assessed using the Chinese version of Personalized Psychological Flexibility Index and Chinese version of the 5-item WHO Well-Being Index, respectively. Correlation analysis showed that psychological flexibility was positively associated with well-being (r = 0.220, p < 0.05) and negatively correlated with mental health issues (r = ‒0.225, p < 0.05). Night shift frequency was linked to mental health issues (r = 0.276, p < 0.05) and lower psychological flexibility (r = ‒0.165, p < 0.05). Structural equation modeling demonstrated that age had direct positive effects on psychological flexibility (β = 0.130) and mental health (β = 0.541), while night shift frequency directly worsened mental health (β = 0.618) and reduced psychological flexibility (β = ‒0.198). Psychological flexibility significantly influenced both mental health (β = ‒0.674) and well-being (β = 0.418), with indirect effects on well-being (β = 0.268). Mental health was the strongest predictor of well-being (β = 0.718).

However, these clocks can partly reduce this loss by advancing sleep phase due to advancing the pattern of 24-h exposure to light caused by earlier risetimes. In an in silico study, a model of sleep-wake regulation was applied to show that the difference between earlier and later weekday risers in weekday risetime is equal to the sum of differences between them in sleep loss and sleep phase advance that can be measured as their differences in weekend-weekday gap in risetime and in weekend risetimes, respectively. Such differences in sleep loss and sleep phase advance were estimated from bed- and risetimes self-reported for weekdays and weekends by 4940 university students and lecturers subdivided into subsamples with different weekday risetimes and chronotypes. We also estimated, for these subsamples, the percentages of weekday sleep insufficiency and circadian misalignment determined as a less than 6 hours in bed on weekdays and a larger than 3-h weekend-weekday gap in risetime, respectively. Additionally, advance phase shifts of the circadian clocks were predicted by model-based simulations of self-reported sleep times.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"770-783"},"PeriodicalIF":2.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144180449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
