چکیده

Shift work is associated with irregular eating behaviors, increased energy intake, and impaired sleep quality. Poor dietary patterns may elevate systemic inflammation, contributing to long-term metabolic and cardiovascular risks. The aim of this study was to investigate differences in the Dietary Inflammatory Index (DII), sleep quality, dietary intake, and anthropometric and body composition measures between fixed daytime workers and rotating shift workers and to examine the associations among these parameters. This cross-sectional study included 52 male workers employed at a defense industry factory in Ankara, Türkiye, who worked either fixed daytime or rotating shifts. Dietary intake was assessed using 24-h dietary recalls for three non-consecutive days, from which macronutrient and micronutrient intakes were calculated. DII scores were computed to assess the inflammatory potential of the diet. Sleep quality was evaluated using the Pittsburgh Sleep Quality Index (PSQI). Anthropometric measurements, body composition, blood pressure, and biochemical parameters, including fasting plasma glucose, lipid profile (total cholesterol, HDL-C, LDL-C, and triglycerides), C-reactive protein, and homocysteine, were measured using standardised protocols. Rotating shift workers had significantly higher total energy intake and higher daily intakes of fructose, total fat, saturated and monounsaturated fatty acids, cholesterol, and several micronutrients, including vitamin A, folate, iron, calcium, and phosphorus compared with fixed daytime workers (p < 0.05). Mean DII scores did not differ significantly between the groups (Fixed daytime: 0.2 ± 1.86; rotating shift: −0.2 ± 2.25). DII scores were positively correlated with global PSQI score (r = 0.278, p = 0.046), the PSQI sleep duration component score (r = 0.319, p = 0.021), and daytime dysfunction component score (r = 0.287, p = 0.039); however, the association between DII and overall sleep quality was no longer statistically significant after adjustment for potential confounding factors (age, BMI, smoking status, physical activity, and work schedule). These findings suggest that dietary habits, pro-inflammatory dietary patterns, and poor sleep quality may represent co-existing factors associated with metabolic risk, and addressing these factors may contribute to better overall metabolic health.

چکیده به فارسی

کار شیفتی با رفتارهای نامنظم غذایی، افزایش دریافت انرژی و کاهش کیفیت خواب همراه است. الگوهای غذایی نامطلوب ممکن است التهاب سیستمیک را افزایش داده و در نتیجه خطرات متابولیک و قلبی‌عروقی بلندمدت را افزایش دهند. هدف این مطالعه بررسی تفاوت‌های شاخص التهابی رژیم غذایی (DII)، کیفیت خواب، دریافت غذایی و اندازه‌گیری‌های آنتروپومتریک و ترکیب بدن بین کارکنان مرد با شیفت ثابت روزانه و کارکنان شیفت چرخشی و همچنین بررسی ارتباط میان این پارامترها بود. این مطالعه مقطعی شامل ۵۲ کارگر مرد شاغل در یک کارخانه صنایع دفاعی در آنکارا، ترکیه بود که به صورت شیفت ثابت روزانه یا شیفت چرخشی کار می‌کردند. دریافت غذایی با استفاده از یادآوری غذایی ۲۴ ساعته برای سه روز غیرمتوالی ارزیابی شد و دریافت درشت‌مغذی‌ها و ریزمغذی‌ها محاسبه گردید. امتیازهای DII برای ارزیابی پتانسیل التهابی رژیم غذایی محاسبه شد. کیفیت خواب با استفاده از شاخص کیفیت خواب پیتسبورگ (PSQI) ارزیابی گردید. اندازه‌گیری‌های آنتروپومتریک، ترکیب بدن، فشار خون و پارامترهای بیوشیمیایی شامل گلوکز پلاسمای ناشتا، پروفایل لیپیدی (کلسترول تام، HDL-C، LDL-C و تری‌گلیسرید)، پروتئین واکنشی C و هموسیستئین با استفاده از پروتکل‌های استاندارد اندازه‌گیری شد. کارکنان شیفت چرخشی دریافت انرژی کل و دریافت روزانه فروکتوز، چربی کل، اسیدهای چرب اشباع و تک‌غیراشباع، کلسترول و چندین ریزمغذی از جمله ویتامین A، فولات، آهن، کلسیم و فسفر به طور معناداری بالاتری نسبت به کارکنان شیفت ثابت روزانه داشتند (p < 0.05). میانگین امتیازهای DII بین دو گروه تفاوت معناداری نداشت (شیفت ثابت روزانه: ۰.۲ ± ۱.۸۶؛ شیفت چرخشی: ‎−۰.۲ ± ۲.۲۵). امتیازهای DII با امتیاز کلی PSQI (r = 0.278, p = 0.046)، امتیاز مؤلفه مدت خواب PSQI (r = 0.319, p = 0.021) و امتیاز مؤلفه اختلال عملکرد روزانه (r = 0.287, p = 0.039) همبستگی مثبت داشت؛ با این حال، پس از تعدیل برای عوامل مخدوش‌کننده بالقوه (سن، BMI، وضعیت سیگار کشیدن، فعالیت بدنی و برنامه کاری)، ارتباط بین DII و کیفیت کلی خواب از نظر آماری معنادار نبود. این یافته‌ها نشان می‌دهد که عادات غذایی، الگوهای غذایی پیش‌التهابی و کیفیت پایین خواب ممکن است عوامل هم‌زمان مرتبط با خطر متابولیک باشند و پرداختن به این عوامل می‌تواند به بهبود سلامت متابولیک کلی کمک کند.

Supporting life beyond the finish line: A cross-sectional analysis of retirement transition policies for professional riders in European cycling

Michael Liebrenz Journal Of Science & Cycling, 2026

چکیده

Transitioning out of professional sport can present challenges for athletes and their wider environments, frequently necessitating coordinated physical, psychological, and economic support. Although these concerns have been documented in elite cycling, the extent to which structured transition programmes exist within the sport remains insufficiently understood, particularly in Europe, the historical centre of professional cycling. We conducted a cross-sectional qualitative documentary analysis, distributing a standardised inquiry to all European Cycling Federations (ECFs; N = 51) between December 2024-March 2025. Federations were asked whether they had formal strategies, policies, or resources related to athlete retirement. Responses were categorised as “ECF-level literature or initiative”, “No ECF-level provision”, or “No response” and relevant materials were descriptively synthesised. Amongst the 21 federations that responded, the majority (n = 17; ≈81%) reported no ECF-level retirement initiatives. Common reasons included limited resources, low perceived demand, or reliance on national or international bodies (i.e., Olympic Committees or sport-specific unions). Four ECFs (~19%) described transition-related structures, though these varied considerably in scope, definition, and delivery. Despite well-documented needs, structured retirement support for professional cyclists remains uncommon across European national federations, and existing programmes appear heterogeneously applied. As cycling expands globally, effective transition planning becomes increasingly important for athlete wellbeing and the long-term sustainability of the sport. Holistic, international collaborations led by cycling’s major governance bodies could strengthen career-long support systems, reinforce the public image of cycling as a health-promoting discipline, and create responsible, athlete-centered ecosystems.

Sukamdani Amanjaya; Nazaruddin; Asbath Jurnal Riset Keperawatan dan Kesehatan, 2026, Vol. 3, Issue 5, pp. 442-452 https://doi.org/10.71203/jrkk.v3i5.193

چکیده

Background: Patients with chronic kidney disease undergoing hemodialysis frequently experience physical and psychological complaints that may affect their sleep quality. Uremic pruritus, restless legs syndrome, anxiety, and post-hemodialysis fatigue are potential factors that may disrupt sleep quality. Objective: This study aimed to identify the factors influencing the sleep quality of patients with chronic kidney disease undergoing hemodialysis at Bahteramas Regional General Hospital, Southeast Sulawesi Province. Methods: This study employed a quantitative analytical approach with a cross-sectional design. The sample consisted of 83 respondents. Data were collected using the Pittsburgh Sleep Quality Index (PSQI), 5-D Itch Scale, International Restless Legs Syndrome Rating Scale (IRLS), Hospital Anxiety and Depression Scale-Anxiety (HADS-A), and a post-hemodialysis fatigue assessment instrument. Data were analyzed using the Chi-square test and binary logistic regression. Results: Bivariate analysis showed that uremic pruritus (p = 0.046), restless legs syndrome (p = 0.015), anxiety (p = 0.029), and post-hemodialysis fatigue (p = 0.049) were statistically significant factors associated with sleep quality. Simultaneously, the four variables had a statistically significant effect on sleep quality (p = 0.007), with a Nagelkerke R Square value of 0.217. In the multivariable analysis, only anxiety showed a statistically significant independent effect (p = 0.019). Conclusion: Uremic pruritus, restless legs syndrome, anxiety, and post-hemodialysis fatigue were statistically associated with sleep quality in the bivariate analysis. The four variables were jointly significant in the multivariable model, whereas only anxiety remained statistically significant after adjustment for the other variables.

Digital dinacharya and workplace burnout: a cross-sectional analytical study of occupational health

Neha S. Maske; Kirti Bhausaheb Gaikwad; Meera K Bhojani International Journal of Research in Medical Sciences, 2026, Vol. 14, Issue 11, pp. 5233-5240 https://doi.org/10.18203/2320-6012.ijrms20264183

چکیده

Background: Prolonged screen exposure, after-hours connectivity, and sedentary work are linked to poor sleep and occupational burnout among Indian working professionals. Ayurvedic Dinacharya regulates waking, Vyayama, Bhojana Vidhi, and Nidra Vidhi; however, digital-era disruption of these domains among working adults remains unstudied. This study aimed to assess digital lifestyle behaviours mapped to Dinacharya principles as behavioural markers of Pragyaparadha, in relation to sleep quality and occupational burnout among working adults, and to identify behaviours independently associated with poor sleep and higher burnout. Methods: A cross-sectional analytical survey (STROBE-reported) was conducted at the All-India Institute of Ayurveda (AIIA), New Delhi, during (January 2026 to July 2026), among 400 working adults aged 25-40 years with ≥1 year of occupational experience. A structured proforma captured sociodemographic details and Dinacharya-mapped digital behaviours across five domains (morning routine, bedtime device use, after-hours connectivity, screen breaks/sedentary time, mealtime practices). Sleep quality and burnout were assessed using the PSQI and Copenhagen burnout inventory. Results: Of 400 participants, 56.8% had poor sleep quality, 61% personal burnout, and 55.8% work-related burnout. Bedtime device use and inadequate screen breaks/sedentary behaviour independently predicted poor sleep (aOR 1.76 and 1.98). After-hours connectivity, sedentary behaviour, and mealtime digital engagement predicted personal burnout; bedtime device use, sedentary behaviour, mealtime digital engagement, and digital overload predicted work-related burnout (all p<0.05). Conclusions: Digital lifestyle behaviours reflect patterns of Pragyaparadha in daily digital conduct. Interpreted through Dinacharya and Nidra, the findings support a culturally grounded, preventive Digital Dinacharya framework for digital-era occupational health.

Childhood Emotional Neglect, Psychological Distress: Moderating role of Peer Support in Young Adults

Saba Noreen; Zarrin Atif International Journal of Emerging Multidisciplinaries Social Science, 2026, Vol. 5, Issue 6, pp. 18-45 https://doi.org/10.54938/ijemd-ss.2026.05.6.875

چکیده

Psychological distress during young adulthood may be influenced by early emotional experiences and current interpersonal relationships. The current study investigates the relationship between childhood emotional neglect, peer support and psychological distress in young adults. A quantitative research design was used with 200 participants aged 18-25 years selected through purposive sampling from educational institutions of Lahore. Childhood emotional neglect, peer support and psychological distress were measured with the Childhood Emotional Neglect Questionnaire (CENQ), Multidimensional Scale of Perceived social support (MSPSS), and Kessler Psychological Distress Scale (K10), respectively. Data were analyzed using Pearson- product moment correlation, hierarchical regression, PROCESS moderation analysis and one way ANOVA. Childhood emotional neglect was significantly and positively associated with psychological distress while peer support was not significantly and directly associated with psychological distress. Hierarchical regression indicates that psychological distress was significantly predicted by childhood emotional neglect, while peer support was not a significant direct predictor. The regression model explained 12.5% of variance in psychological distress. Moderation analysis showed significant interaction effects of friends’ support (P= .017) and family support (P= .032), indicating that these sources of support moderated the relationship between childhood emotional neglect and psychological distress. There were significant socio-economic differences for childhood emotional and peer support, but not for psychological distress. The findings highlight the importance of considering childhood emotional experiences and interpersonal resources when understanding psychological distress among young adults.
