Association of chronotype, breakfast habits, and sleep quality with BMI-for-Age in adolescents

This study aims to evaluate the relationship between sleep quality and breakfast habits among students at the School of Health. A cross-sectional descriptive study was conducted with 291 students at Tekirdağ Namık Kemal University School of Health between January and May 2020. Data was collected through a questionnaire that included sociodemographic characteristics, anthropometric information, breakfast habits, and sleep patterns. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Multiple linear regression was used to understand breakfast behaviour and other factors affecting the PSQI total score. The mean age of the participants was 20.78 (±2.33) years, and 75% were women. The study revealed that 68% of the participants had poor sleep quality, and 76% of those with good sleep quality had regular breakfast habits (p<0.05). Multiple linear regression analysis showed that consuming eggs less than 1-2 times a week (β=1.45) and consuming filter coffee every day (β=1.44) increased PSQI scores, indicating poorer sleep quality. Conversely, regular breakfast (β=-0.78) and lunch (β=-0.62) consumption were associated with lower PSQI scores, indicating better sleep quality (R²=0.21, p<0.01). This study found a significant bidirectional relationship between sleep quality and breakfast habits among university students. Regular breakfast consumption, adherence to meal timing, and minimizing the time interval between the last meal and bedtime are associated with better sleep quality.

Introduction: The nutritional status of school-age children is still a problem and a global concern, the incidence of malnutrition in the world reaches 149.2 million children. One of the influencing factors is breakfast habits. The importance of a healthy breakfast can meet 15-30% of the recommended daily nutritional needs. This study aims to analyze the relationship between breakfast habits and the nutritional status of school-age children. Methods: This type of research is a correlational analytical study with a cross-sectional approach. A total of 90 elementary school students were recruited by total sampling. Data collection was carried out using a breakfast habit questionnaire filled out by respondents and nutritional status was determined based on body weight and height measurements. Data analysis was carried out to determine the frequency distribution and percentage of each variable studied. The statistical analysis used was the Spearman rho test (p value <0.5). Results: The results showed that most students had poor breakfast habits (66.7%) and poor nutritional status (60%). The results of the relationship test showed that there was a relationship between breakfast habits and nutritional status (p = 0.000). Conclusion: Breakfast habits related to the nutritional status of elementary school students, it is expected that parents can improve their parenting patterns and knowledge of the importance of breakfast for children properly and balanced nutritional intake so that nutritional status is in the good category.

Background: In Indonesia, a country that has been listed as one of the least concentrated due to the lack of economy to provide the necessary food, 40% of the students were found to have no breakfast and 50% of the students were found to have no concentration, affecting 50% of the learning performance. this study was to determine the relationship between the breakfast habits and the quality of sleep with the learning concentrationMethod: This research was conducted in May 2024, the site selected was class XI students of SMAN 10 Tanjung Jabung Timur with cross-sectional design. Subjects was 94 people by filling a questionnaire on breakfast habits, sleep quality and learning concentration. The sampling technique used was the convenience sampling technique. Data analysis employs univarian and bivariat statistical test, using spearman correlation.Result: The results showed that as many as 59.6 per cent of the respondents had good breakfast habits, as many as 57.4 per cent of the respondents had poor sleep quality and 55.3 per cent of the respondents were not concentrated. The results of the correlation test between breakfast habits and study concentration showed a p-value of 0.093>0.05. However, the correlation test between sleep quality and study concentration shows a p-value of 0.004 <0.05.Conclusion: There is no relationship between breakfast habits and study concentration and a significant relationship between sleep quality and study concentration.

Background: The relationship between certain breakfast consumption habits and mental health has been reported previously, many observational studies showed association between breakfast routine and academic performance.

Background: With increased life expectancy and changes in lifespan, now women spend more years after menopause. Women with menopausal symptoms may experience a lower quality of life (QoL) and complain about poor sleep quality. This study aimed to examine the relationship between QoL and sleep quality in postmenopausal women. Methods: This research was a predictive correlational study. The study sample was 200 postmenopausal women referred to the healthcare centers affiliated with Mashhad University of Medical Sciences in Mashhad City, Iran, in 2021. The subjects were selected through multistage cluster sampling. To assess the quality of sleep and life quality, the Pittsburgh Sleep Quality Index (PSQI) and Menopause-Specific QoL questionnaire (MENQOL) were used. The obtained data were analyzed by the Pearson correlation coefficient and multiple linear regression in SPSS software, version 21. The significance level was set at P<0.05. Results: The mean±SD age of the subjects was 53.92±6.13 years. Their mean±SD scores of sleep quality and QoL were 48.62±21.98 and 4.93±2.74, respectively, and 37% of women had sleep disorders. The multiple determination coefficient for the linear regression model was equal to 0.35, and there was a significant direct relationship between sleep quality and QoL (b=3.72, 95% CI =2.70-4.74, P<0.001). So for each unit change in sleep quality, the average QoL score increased by 3.72 units. Conclusion: Considering the relationship between sleep quality and QoL in postmenopausal women, it is recommended that these women use appropriate methods to improve sleep quality. Also, health professionals should keep this issue in mind when examining the health status of this group of women.

A saffron extract has been found to be effective in the context of depression and anxiety, but its effect on sleep quality has not been investigating yet using objective approaches. For this purpose, a randomized double-blind controlled study was conducted in subjects presenting mild to moderate sleep disorder associated with anxiety. Sixty-six subjects were randomized and supplemented with a placebo (maltodextrin) or a saffron extract (15.5 mg per day) for 6 weeks. Actigraphy was used to collect objective data related to sleep quality at baseline, at the middle and at the end of the intervention. Sleep quality was also assessed by completion of the LSEQ and PSQI questionnaires and quality of life by completion of the SF-36 questionnaire. Six weeks of saffron supplementation led to an increased time in bed assessed by actigraphy, to an improved ease of getting to sleep evaluated by the LSEQ questionnaire and to an improved sleep quality, sleep latency, sleep duration, and global scores evaluated by the PSQI questionnaire, whereas those parameters were not modified by the placebo. In conclusion, those results suggest that a saffron extract could be a natural and safe nutritional strategy to improve sleep duration and quality.

Games online can be accessed wherever and whenever . Playing games can make players happy, because it gives psychological satisfaction. The more interested in playing the game, the more time is spent to achieve pleasure. It can be said that someone is experiencing addiction if the individual is stopped from play will feel anxiety.

Objective: Elementary school age children nutrition problems are the impact of an imbalance between food intake and nutrients released by the body. This can be caused by not having breakfast habits. Eating breakfast has the benefit of maintaining endurance and increasing learning concentration. The breakfast habit provides the energy and nutrients needed to carry out various activities throughout the day such as school, study, and play optimally. This study aims to determine the relationship between breakfast habits and nutritional status of elementary school children.Methods: This research was conducted at SD Muhammadiyah Terpadu Ponorogo class 4 and 5 with a sample of 113 students. The measuring instrument used was a questionnaire to explore the variables of breakfast habits, while to determine the nutritional status of students using a weighing scale. Nutritional status was calculated IMT/U. The bivariate analysis test used the Chi Square test of significance level 0.05Results: Chi square test results obtained p-value 0.406 means that there is no relationship between breakfast habits and nutritional status of school age children at SD Muhammadiyah Terpadu Ponorogo. Many factors influence nutritional status. Respondents do not usually eat breakfast, but during recess they eat by buying a canteen and in their daily life they like to eat vegetables and fruit so there is no problem with nutritional intake.Conclusion: Researchers recommend to the next researchers to dig deeper about the composition of the food at the time the respondent had breakfast.

The Pittsburgh Sleep Quality Index (PSQI) is the most common measure of sleep quality. Its questions refer to "usual" sleep habits during the last month. Considering how different sleep-wake behavior can be between workdays and work-free days, we hypothesized that sleep quality should show similar differences. We investigated these potential differences in a cross-sectional online study using the original and two adapted versions of the PSQI that replaced "usual" by explicitly referring to sleep on workdays or work-free days. Additionally, we investigated how these scores relate to chronotype and social jetlag assessed by the Munich ChronoType Questionnaire. Participants were recruited online, they had to be older than 18 years, following regular weekly work schedules, and they should not be shift workers. Repeated-measures analysis of variance was used to compare the three different versions of the PSQI (usual, work, and work-free). To find out whether PSQI score differences could be predicted by chronotype and/or social jetlag a mediation analysis was carried out. Workday PSQI scores were similar to the original "usual" scores, two points higher than the PSQI score on work-free days and above the cutoff designating poor sleep quality. PSQI components and time variables also differed between workdays and work-free days. Chronotype correlated with the difference between PSQI scores on workdays and on work-free days, an association mediated by social jetlag. Our results suggest that the original PSQI predominantly reports sleep quality on workdays and that work schedules may affect sleep quality. The mediation of social jetlag on the association of chronotype and PSQI score differences could mean that not chronotype per se, but rather the collision of an individuals' chronotype with fixed work schedules explains the differences between sleep on workdays and work-free days. Understanding how sleep quality differs between workdays and work-free days, how this difference can adequately be assessed through directing participants to focus on their sleep specifically on workdays vs. work-free days, and how circadian factors modulate this difference, is crucial to improve sleep quality.

To analyse whether poor breakfast habits in adolescence predict the metabolic syndrome and its components in adulthood. Previous studies suggest that regular breakfast consumption improves metabolic parameters. Prospective. Breakfast habits and other lifestyle variables at age 16 years were assessed from questionnaires. Poor breakfast habits were defined as skipping breakfast or only drinking or eating something sweet. At age 43 years, the effective sample consisted of 889 participants defined as having the metabolic syndrome or not, using the International Diabetes Federation criteria. Logistic regression was used to calculate odds ratios and confidence intervals. The Northern Swedish Cohort, a longitudinal population-based cohort with 27-year follow-up. Adolescents (age 16 years). Prevalence of the metabolic syndrome at age 43 years was 27·0 %. Of the participants, 9·9 % were classified with poor breakfast habits at age 16 years. Adjusted odds for the metabolic syndrome at age 43 years was OR = 1·68 (95 % CI 1·01, 2·78) for those with poor breakfast habits at age 16 years compared with breakfast eaters. Looking at the metabolic syndrome components, poor breakfast habits at age 16 years were associated with central obesity (OR = 1·71; 95 % CI 1·00, 2·92) and high fasting glucose (OR = 1·75; 95 % CI 1·01, 3·02) at age 43 years, even after multivariate adjustments. Poor breakfast habits in adolescence predicted the metabolic syndrome in adulthood. Of the metabolic syndrome components, poor breakfast habits in adolescence predicted central obesity and high fasting glucose in adulthood. Further research is needed to fully understand the relationship between early breakfast habits and adult metabolic syndrome.

ObjectivesThis study explores the relationships among chronotype, sensation seeking, sleep quality and depressive symptoms in adolescents with diagnosed depression, aiming to clarify the mechanisms by which chronotype is associated with depression.MethodsThis cross-sectional study assessed 216 adolescents with diagnosed depression using a demographic questionnaire, the Morningness-Eveningness Questionnaire, the Sensation Seeking Scale, the Pittsburgh Sleep Quality Index, and the Beck Depression Inventory. Descriptive and correlational analyses were performed using SPSS 27.0, and structural equation modeling was conducted via AMOS to explore the mediating roles of sensation seeking and sleep quality in the relationship between chronotype and depression.ResultsThe study found that 60.6% of adolescents with depression were evening chronotypes. Evening chronotype was associated with higher sensation seeking (r = -0.134, p < 0.05), poorer sleep quality (r = -0.303, p < 0.01), and more severe depressive symptoms (r = -0.376, p < 0.01). Chronotype showed a direct effect on depressive symptoms (effect size = -0.318, 95% CI = -0.602 to -0.049, p < 0.05) and an indirect effect via sleep quality, accounting for 80.5% of the total effect. While sensation seeking alone was not a significant mediator, it contributed to a chain mediation with sleep quality, accounting for 13% of the total effect (combined effect size = -0.053, 95% CI = -0.163 to -0.005, p < 0.01).ConclusionsChronotype may play a significant role in adolescent depression, with both direct and indirect effects mediated by sleep quality and sensation seeking. The findings highlight the potential importance of sleep quality as a mediating factor, indicating that interventions targeting sleep improvement could be a promising avenue for further exploration in alleviating depressive symptoms in adolescents.
