“…In addition, people who sleep later or sleep poorly are more likely to change their eating habits, such as missing or not being in time for meals, which also indicates a higher frequency of skipping breakfast. It is obvious that the evening type is more likely to skip breakfast, which is consistent with previous research [ 36 , 37 , 38 , 39 , 40 ]. Different SCs represent different active hours: morning and intermediate types tend to be active in the morning or during the daytime, while evening types are active late at night.…”

Sleep disorders, which are prominent problems among college students, may be associated with skipping breakfast. Therefore, we aimed to explore the role of sleep chronotypes and depressive symptoms as mediators in the relationship between breakfast frequency and sleep quality. A cross-sectional survey enrolling random samples of 712 college students was conducted by the Questionnaire Star online platform. Statistical description and correlation analysis were performed by SPSS 25.0, and a chain mediation test was performed by model 6 in PROCESS 3.5. The result of the article demonstrated that breakfast frequency can affect sleep quality through two mediating pathways: ① sleep chronotypes, with a mediating effect of 32%; and ② depressive symptoms, with a mediating effect of 52.4%. However, the chain mediating effects of sleep chronotypes and depressive symptoms was not significant, and neither was the direct effect of breakfast frequency on sleep quality. Breakfast frequency can indirectly affect sleep quality by adjusting sleep chronotypes and depressive symptoms. Regular breakfast can increase morning and intermediate sleep chronotypes, reduce depressive symptoms, and thus improve sleep quality.

“…Notably, during the first COVID-19 lockdown in Italy, a cross-sectional study revealed a change in eating habits for 58% of its participants in terms of mealtimes or content of meals. Being an evening chronotype and experiencing poor sleep implied a higher risk of changing eating habits, including a delay in the timing of meals [59]. A nested casecontrol study also showed that during the COVID-19 pandemic, its participants consumed their breakfast less regularly than before the COVID-19 pandemic, suggesting that meal The main ways by which IF exerted positive effects on weight loss were reduced energy intake due to the limited eating window, depletion of liver glycogen, and activation of fat storage as energy fuel [53].…”

Background: The concept of time-restricted eating (TRE) or time-restricted feeding (TRF) promotes daily periods of feeding and fasting to determine whole-body physiology. Chronic misalignment of circadian rhythms or chrono-disruption is related to an increased risk of diverse metabolic disorders. The progression of non-communicable diseases seems to be affected by the timing of meals. As a result, intermittent fasting is a promising approach for their management. The aim of the present literature review is to examine and scrutinize the TRE protocols in the fields of prevention and management of metabolic disorders. Methods: This is a thorough literature review of the reported associations among circadian rhythm, metabolic disorders, diabetes mellitus, obesity, TRE, TRF, dietary habits, circadian disruption, cardiovascular diseases, atherosclerosis, and non-alcoholic fatty liver to find the already existing clinical studies from the last decade (2014–2024) in the most precise scientific online databases, using relevant specific keywords. Several inclusion and exclusion criteria were applied to scrutinize only longitudinal, cross-sectional, descriptive, and prospective clinical human studies. Results: The currently available clinical findings remain scarce and suggest that chrononutrition behaviors such as TRE or TRF may promote several metabolic benefits, mainly in body weight control and fat loss. Improvements in glucose levels and lipid profiles are currently quite controversial since some clinical studies show little or no effect. As far as liver diseases are concerned, the efficacy of intermittent fasting seems to be stronger in the management of non-alcoholic fatty liver disease due to body weight decline and fat loss. Conclusions: Even if there has been a gradual increase in clinical studies in the last few years, providing promising perspectives, currently, there is no conclusive evidence for the role of chrononutrition in metabolic disorders. Future studies should be well-designed with longer duration and larger sample sizes. Moreover, it is important to examine the best timing of the eating window and its feasibility.

Bu çalışmada, okul öncesi dönem çocuklarının koronavirüs hastalığı-2019 [coronavirus disease-2019 (COVID-19)] ile değişen yaşam tarzı alışkanlarını belirlemek ve beslenme alışkanlıkları riskini saptamak amaçlanmıştır. Gereç ve Yöntemler: Araştırma, 3-6 yaş arasındaki 739 okul öncesi dönem çocuğun katılımı ile gerçekleştirilmiştir. Katılımcıların genel özellikleri, yaşam tarzı ve beslenme alışkanlıkları bir anket formu aracılığıyla yüz yüze görüşme tekniği ile sorgulanmıştır. Beslenme Alışkanlıkları Risk İndeksi aracılığı ile beslenme riski değerlendirilmiştir. Vücut ağırlığı ve boy uzunluğu ölçülüp yaşa göre beden kitle indeksi z-skoru hesaplanmıştır. Bulgular: Çocukların yaş ortalamaları 4,73±1,05 yıl ve yaşa göre beden kitle indeksi z-skoru ortalamaları 0,51±1,84'tür. COVID-19 öncesinde ortalama Beslenme Alışkanlıkları Risk İndeksi puanının (8,96±2,79), pandemi sürecinde (10,26±2,89) anlamlı düzeyde arttığı belirlenmiştir (p<0,001). COVID-19 öncesine göre çocukların fiziksel aktivitelerinin azaldığı (p<0,001), öğün saati düzenlerinin bozulduğu (p<0,001), uyku sürelerinin ve ekran maruziyetinin arttığı (sırasıyla p=0,001; p<0,001) belirlenmiştir. Pandemi öncesi yüksek Beslenme Alışkanlıkları Risk İndeksi puanı (p<0,001), kahvaltıyı atlama (p=0,011), tokluk hissine rağmen atıştırma (p<0,001) ve erkek cinsiyet (p=0,019) pandemi sürecindeki Beslenme Alışkanlıkları Risk İndeksi puanını etkilemektedir. Sonuç: Pandemi sürecinde, okul öncesi dönem çocuklarında olumsuz sağlık sonuçlarına neden olabilecek yaşam tarzı alışkanlıklarında değişiklikler belirlenmiş ve beslenme riskinin arttığı saptanmıştır. Beslenme riskini azaltmak için sağlıklı beslenme alışkanlıkları ile düzenli fiziksel aktivite, yeterli uyku süresi ve düşük ekran maruziyeti gibi yaşam tarzı alışkanlıklarında da değişiklikler önerilmektedir. Anah tar Ke li me ler: Beslenme Alışkanlıkları Risk İndeksi; COVID-19; okul öncesi dönem çocukları ABS TRACT Objective: It was aimed to determine the changing dietary and lifestyle habits of preschool children with coronavirus disease-2019 (COVID-19) and to determine the risk of dietary habits. Material and Methods: The study was conducted with the participation of 739 preschool children aged 3-6 years. Participants' general characteristics, lifestyle, and nutrition habits were questioned through a questionnaire form using a face-to-face interview technique. Dietary risk was assessed using the Dietary Habits Risk Index. Body weight and height were measured and body mass index z-score for age was calculated. Results: The mean age of the children was 4.73±1.05 years and the mean body mass index z-score for age was 0.51±1.84. The average Dietary Habits Risk Index score before COVID-19 (8.96±2.79) was shown to have increased significantly throughout the pandemic (10.26±2.89) (p<0.001). It has been determined that children's physical activities have decreased (p<0.001), mealtime patterns have been disrupted (p<0.001), and their sleep duration and screen exposure have increased compared to before COVID-19 (respectively p=0....
