Predictors and disturbances of sleep quality between men and women: results from a cross-sectional study in Jordan

BackgroundSleep disturbances, a public health concern that may lead to critical physiological conditions, are associated with personal characteristics such as gender. Limited evidence is available from the Middle East population on the gender disparities in sleep quality. Therefore, the current study examined gender-specific differences in sleep quality and disturbances among Jordanian citizens.MethodA cross-sectional design was used to recruit a convenient sample of 1,092 adults from different Jordanian cities. Data was collected using a self-reported questionnaire comprising the Pittsburgh Sleep Quality Index (PSQI), which was distributed online via social media networks. The participants were categorized according to their global PSQI scores into poor (PSQI ≥ 5) and good sleepers (PSQI < 5). The analysis focused on finding differences between women and men in terms of sleep quality and the effects of demographic, lifestyle, and socioeconomic factors on reported sleep problems.ResultsWomen were revealed to have a higher prevalence of all types of sleep disturbances than men. Women who were over 55 (compared to younger than 20 years), did not smoke, had multiple jobs or part-time employment (compared to unemployed women), and had a monthly income of more than 500 JD (compared to those with an income of < 500 JD) were less likely to experience poor sleep than other women. In contrast, men who neither smoked nor drank coffee, ate no sweets or only one to two pieces daily (compared to participants who ate more than two pieces daily), and worked fixed night shifts (compared to alternating shifts workers) were less likely to experience poor sleep than other men.ConclusionThis study builds a more nuanced understanding of how different demographic, lifestyle, and socioeconomic factors - such as a participant’s age, time of working duty, income, daily sweet consumption, daily caffeine consumption, and smoking - affect the sleep quality of men and women. Thus, promoting a healthier lifestyle for both genders by modifying risk factors - such as smoking cessation, as well as reducing their intake of caffeine and sweets - is the first step toward improving their sleep quality. Further studies are needed to examine how the social role of Arabic women affects their sleep.

Effectiveness of Dexmedetomidine vs Propofol in Post-Open Heart Surgery Patients: A Prospective, Randomized, Double-Blind Study at the PLA Army Central Hospital in Beijing, China

Introduction: Dexmedetomidine and propofol are sedation drugs commonly used in patients after open heart surgery. The aim of this study was to compare the effectiveness of dexmedetomidine and propofol in patients after open heart surgery in terms of sleep quality, delirium, and hemodynamics.&#x0D; Methods: A prospective, randomized, double-blind study was conducted on 120 patients after open heart surgery at the PLA Army Central Hospital in Beijing, China. Patients were randomized to receive dexmedetomidine (n = 60) or propofol (n = 60). Sleep quality was measured using the Pittsburgh Sleep Quality Scale (PSQI), delirium was measured using the confusion assessment method for the intensive care unit (CAM-ICU), and hemodynamics were monitored continuously.&#x0D; Results: Patients receiving dexmedetomidine had lower PSQI scores (p &lt; 0.05) and a lower incidence of delirium (p &lt; 0.05) compared with patients receiving propofol. There were no significant differences in hemodynamic parameters between the two groups.&#x0D; Conclusion: Dexmedetomidine is more effective than propofol in improving sleep quality and reducing delirium in patients after open heart surgery.

The Effect of Baby Massage on Nursing Care for Healthy Babies to Improve Sleep Quality and Smooth Defecation

Baby massage is a form of physical touch that provides many benefits for babies, including improving sleep quality and smooth bowel movements. This study aims to determine the effect of baby massage on nursing care for healthy babies to improve sleep quality and smooth defecation in babies in Purwakarta Regency, Indonesia. This research is experimental research with a pre-test and post-test design. The research sample was 30 healthy babies aged 3-12 months who were grouped into two groups, namely the intervention group (15 babies) and the control group (15 babies). The intervention group was given baby massage for 10 minutes every day for 7 days. The control group was not given any treatment. Data on sleep quality and bowel movement were collected before and after the intervention. The results showed that there were significant differences between the intervention group and the control group in terms of sleep quality and smooth defecation. The intervention group showed greater improvements in sleep quality and smooth defecation compared to the control group. Based on the results of this research, it can be concluded that baby massage has a positive influence on improving sleep quality and smooth defecation in healthy babies.

Healthy Nutrition Attitude, Sleep Quality and Musculoskeletal Disorders in University Students During Covid-19 Pandemic

This study aims to college students' healthy nutrition attitude, sleep status, and musculoskeletal disorders during the COVID-19 pandemic.&#x0D; In total, 165 university students participated in this research. The students filled out the Attitude Scale for Healthy Nutrition, Pittsburgh Sleep Quality Index (PSQI), and Cornell Musculoskeletal Discomfort Questionnaire. The attitude toward healthy eating of 34 (20.6%) students was found to be moderate, 100 (60.6%) high, and 31 (18.8%) very high. There was no meaningful difference between groups according to having COVID-19 disease (p&gt;0.05). Among the participants, 43 (26.06%) students were found to be good and 122 (73.94%) to be poor in terms of sleep quality. The global PSQI and sleep duration subgroup scores of those who had COVID-19 were statistically higher (p=0.010 and 0.043, respectively). The five regions with the most musculoskeletal symptoms were the upper back (78.18%), lower back (70.91%), neck (69.09%), right shoulder (55.76%) and left shoulder (49.09%). Significant differences were observed in the scores of the right wrist (p=0.009), left wrist (p=0.007), right lower leg (p=0.024), left lower leg (p=0.026), right foot (p=0.001), and left foot (p=0.009). The COVID-19 pandemic partially affected university students in terms of healthy eating attitudes and, to a greater extent, in terms of sleep and musculoskeletal disorders.

Sleep at high altitude: A bibliometric study and visualization analysis from 1992 to 2022

BackgroundAs an important monitoring index for adaptation to hypoxia, sleep may reflect the adaptive state of the body at high altitudes. The literature has shown a link between altitude and sleep problems, and sleep changes have become a common problem for individuals at high altitudes, negatively impacting their physical and mental health. As research on high-altitude sleep has gained attention in recent years, the publishing volume has increased worldwide, necessitating a more comprehensive understanding of this field. This manuscript evaluates the key themes and emerging trends in high-altitude sleep over the past few decades and predicts future research directions. MethodsArticles related to high-altitude sleep published from 1992 to 2022 were retrieved from the Web of Science Core Collection, and the relevant literature characteristics were extracted after the screening. Then, bibliometric analyses and visualizations were performed using Microsoft Excel, CiteSpace, VOSviewer, and an online analysis platform (http://bibliometric.com). ResultsA total of 1151 articles were retrieved, of which 368 were included in the analysis, indicating a gradually increasing trend. The United States, Switzerland, and China have made significant contributions in this field. Bloch KE from the University of Zurich was determined to be the most productive and academically influential author in this field. The highest-yielding journal was High Altitude Medicine & Biology. Initially, altitude training was the primary research topic. Currently, research focuses on sleep disorders and sleep apnea. In the coming years, keywords such as “sleep quality,” “prevalence,” and “obstructive sleep apnea” will attract more attention. ConclusionOur findings will assist scholars to better understand the intellectual structure and emerging trends in this field. Future developments in high-altitude sleep research are highly anticipated, particularly in terms of sleep quality at high altitudes and its associated prevalence. This research is also crucial for the improvement and treatment of symptoms during nocturnal sleep in patients with chronic hypoxia due to cardiopulmonary diseases at high altitudes.

Insomnia and behaviorally induced sleep syndrome in undergraduates tested during the COVID-19 pandemic: associations with health, stress, and GPA.

This study was conducted to determine (1) whether the distribution of undergraduates who endorse insomnia or behaviorally induced insufficient sleep syndrome (BIISS) varied during the coronavirus disease 2019 (COVID-19) pandemic relative to normal sleepers and in comparison to values reported pre-pandemic and (2) whether group (insomnia, BIISS, and normal sleepers) was differentially associated with health, stress, and academic achievement mid-pandemic. Two hundred ninety-three undergraduates completed online questionnaires assessing demographics, global sleep quality, insomnia severity, health, and perceived stress; cumulative grade point averages (GPAs) were also collected for each participant. The proportion of participants in each group did not differ from the pre-pandemic values reported in Williams etal (2020). Relative to the normal-sleepers group, the insomnia group reported poorer sleep quality, greater insomnia severity, poorer functioning on measures of physical health, and increased stress; only 1 significant difference was found concerning the BIISS group. Group differences were not found on GPA. Despite the various challenges brought about by the COVID-19 pandemic, the distribution of participants by group was similar to those reported pre-pandemic. The insomnia group fared most poorly in terms of sleep quality, insomnia severity, physical health, and stress. As such, additional effort should be devoted to identifying undergraduates with insomnia to provide treatment that may improve their sleep and their health. Lukowski AF, Kamliot DZ, Schlaupitz CA.

Is There a Link Between Sleep Quality and a Tendency for Eating Disorders?

Aim: Poor sleep quality has been associated with an increased risk of developing eating disorders, and unhealthy eating behaviours. The aim of the study was to explore the potential link between sleep quality and eating disorders. Subjects and Method: This descriptive, observational, and cross-sectional study was conducted with 357 (84 male; 273 female) university students between the ages of 18-25 years. Exclusion criteria included being diagnosed with chronic disease and psychiatric disorders, being pregnant and lactating, using drugs that affect sleep patterns, being shift workers, and participants who did not complete the questionnaire. The questionnaire consisted of six parts including Pittsburgh Sleep Quality Index (PSQI), Three-Factor Eating Questionnaire (TFEQ-21), SCOFF (REZZY) Eating Disorders Scale, anthropometric measurements, demographic properties, and nutritional habits. Results: The prevalence of poor sleep quality was found to be 63% and there was no significant difference between gender in terms of sleep quality (p=0.769). There was significant relationship between total TFEQ 21 (p=0.02), SCORF (REZZY) (p&lt;0.001) scores and sleep quality. Uncontrolled eating behaviours was found higher in students with poor sleep quality (p&lt;0.05). Age, body mass index (kg/m2), and smoking were not significant predictors of sleep quality. However, participants with a tendency towards eating disorders behaviour were found to have a significantly higher risk of poor sleep quality (odds ratio [OR]: 2.338, 95% confidence interval [CI]: 1.444-3.785, p=0.001), as were those with a tendency towards emotional eating behaviour (OR: 1.575, 95% CI: 1.022-2.427, p=0.040). Conclusion: Students with poor sleep quality had higher levels of uncontrolled eating behaviour and a tendency towards unhealthy eating attitudes than those with good sleep quality.

Comparison of Coronavirus Anxiety, Sleep Quality and Quality of Life in Pregnant Women with Healthy Controls

Objective: In the pandemic, pregnant women are at the forefront of the disadvantaged groups and need special needs related to more mental problems. This study aims to evaluate the pandemic anxiety of pregnant women and how their sleep and quality of life are affected. &#x0D; Materials and Methods: 200 pregnant and 200 control patients were included in the study. Informed consent was obtained from the participants. They were asked to fill out the sociodemographic data form, The Coronavirus Anxiety Scale (CAS), the Pittsburgh sleep quality index (PSQI), and the 12-Item Short Form Survey (SF-12) Quality of Life scale. &#x0D; Results: No statistically significant difference was found in the CAS between pregnant and healthy controls (p=0.093). While the physical score subscale of the SF-12 Quality of Life Scale (SF12-PCS) scored statistically significantly higher in pregnant women compared to the healthy controls, the mental score subscale (SF12-MCS) scored significantly lower (respectively: p

How can sleep disorders affect our reaction towards external stressors: a lesson from the COVID-19 outbreak.

The COVID-19 outbreak produced extensive psychological consequences, especially among vulnerable populations. Sleep was identified as one of the most common "indirect targets" of the pandemia, with up to 74.8% of patients surviving from COVID-19 complaining of new-onset sleep disorders. However, so far, the clinic-psychological impact of the outbreak in patients affected by pre-existing sleep disorders has not been examined in details. In the present study, we aim to assess the effect of the COVID-19 outbreak in a cohort of 190 adult patients affected by sleep disorders, compared to 265 age and sex-matched healthy sleepers. The assessment was implemented throughout the use of ad hoc anamnestic questions, exploration of dream content, and validated questionnaires, aiming to capture the broad range of the neuropsychological nuances of the COVID-19 impact. Subjects with pre-existent sleep disorders faced a more severe impact in terms of sleep quality and amount compared to healthy sleepers, presenting longer sleep latency, reduced sleep efficacy, and greater use of hypnotics and medications. On the other hand, healthy sleepers experienced deeper variation in sleeping habits, sleep duration, and greater impact on dream activity in terms of content, emotionality, and presence of recurrent dreams. Finally, in our sample, being female represents an important aggravating factor in the pandemic experience, both in terms of sleep deterioration and with respect to physical and mental health. For instance, females indeed presented the highest scores of Pittsburgh Sleep Quality Index (PSQI) both in cases and control groups (respectively 10 ± 3.8 vs 7.3 ± 3.9 in cases and 6.6 ± 3.6 vs 6.0 ± 3.4 in controls, p-value < 0.001). Pre-existent sleep disorders and the female sex might represent risk factors increasing the clinic-psychological burden in dramatic scenarios, such as the COVID-19 pandemia, requiring dedicated attention from clinicians.

The effect of cognitive-behavioral counseling with or without Citrus aurantium essential oil on sleep quality in pregnant women: a randomized controlled trial.

Sleep disorder is very common during pregnancy. Non-pharmacological treatments are a priority to improve the sleep pattern. This study aimed to determine the effect of cognitive-behavioral counseling with or without Citrus aurantium essential oil on sleep quality (primary outcome) and anxiety and quality of life (secondary outcomes). This randomized controlled trial was performed on 75 pregnant women in Tabriz, Iran. Participants were randomly assigned to the intervention and control groups. The first intervention group received 8 sessions of cognitive-behavioral counseling and aromatherapy with Citrus aurantium essential oil 15-20min before bedtime. The second intervention group received cognitive-behavioral counseling and aromatherapy with placebo and the control group received only routine prenatal care. Pittsburgh Sleep Quality Index, Pregnancy-Specific Quality of life Questionnaire, and Pregnancy-Specific Anxiety Scale were completed before and after intervention. After the intervention based on ANCOVA test and by adjusting the baseline score, the mean score of anxiety in the intervention group 1 (AMD: - 4.54; 95% CI - 6.79 to - 2.28) and intervention group 2 (AMD: - 3.30; 95% CI - 5.60 to - 0.97) was significantly lower than the control group. Also, the mean score of quality of life in intervention group 1 (AMD: 2.55; 95% CI 0.45-4.65) and intervention group 2 (AMD: 2.72; 95% CI 0.60-4.83) was significantly higher than the control group, but there was no statistically significant difference between the study groups in terms of sleep quality (P > 0.05). Also, there was no statistically significant difference between the two intervention groups after the intervention in terms of anxiety (P = 0.379) and quality of life (P = 0.996). Cognitive-behavioral counseling reduced anxiety and improved quality of life. However, further trials are required to reach a definitive conclusion.

Does the presence of radiculopathy affect sleep quality and lower extremity functionality in neuropathic low back pain?

Sleep disturbance in chronic neuropathic low back pain is a well-known condition. In this study, we aimed to investigate the effect of lumbar radiculopathy on sleep quality and lower extremity functionality in the presence of neuropathic low back pain. A total of 79 patients diagnosed with disk herniation, needle electromyography, and neuropathic pain were included in the study. Visual Analog Scale, Pittsburg Sleep Quality Index, and Lower Extremity Functionality Scale were applied to the patients. Of the 79 patients who participated in the study, 34 (43%) were females and 45 (57%) were males. No significant difference was found between the group with and without radiculopathy in terms of sleep quality and lower extremity functionality (p=0.245 and p=0.092, respectively). In our study, a negative correlation was found between night pain and the presence of radiculopathy (p=0.006). The number of lumbar herniated disk levels was higher in the group without radiculopathy and was statistically significant (p=0.023). We found that the presence of radiculopathy did not affect sleep quality and lower extremity functionality in disk herniation patients with neuropathic pain. Although it was not statistically significant in our study, we think that the degree of herniation may affect sleep and lower extremity functionality rather than the number of disk herniation levels with the available data. The fact that neuropathic pain is not limited to disk herniation and radiculopathy, and that neuropathic pain is intertwined with clinical conditions such as anxiety, sleep disorders, and depression are among the conditions that make the studies difficult.

PS-BPR02-10: SYMPATHETIC NERVE TONE AND THE INDOOR ENVIRONMENT IN A HIGHLY INSULATED AND AIRTIGHT MODEL HOUSE DURING THE COLD WINTER SEASON

While evidence for lifestyle modification such as salt reduction, weight loss, exercise, sobriety, and smoking cessation has accumulated for perfect blood pressure control, there is a lack of evidence on blood pressure fluctuations due to housing environments such as thermal protection and heating. In particular, blood pressure fluctuation due to the difference in room temperature between the living room and the dressing room, toilet, and bedroom is known to be a major risk during the winter season. Therefore, this study focused on the autonomic nervous system as one of the factors causing blood pressure fluctuations, and compared the fluctuations when the same subjects spent two days each at home and in a highly insulated, airtight model house. JOURNAL/jhype/04.03/00004872-202301001-00877/figure1/v/2023-10-24T163949Z/r/image-jpeg Subjects were 6 males and 5 females with 20–70 years old. Autonomic activity was measured and calculated using portable electrocardiography (Heartnote: JSR corporation, Tokyo) for the 8 subjects for whom it was possible to measure heart rate, CVRR (Coefficient of variation of R-R interval) and LF(low frequency)/HF(high frequency) ratio. An sympathetic hyperactivation was defined to show more than +2SD for distribution within an individual in LF/HF calculated every 10 seconds. The salivary amylase was measured at several times per day. The indoor environment temperatures were recorded by installing data loggers equipped with temperature sensors in various rooms and taking continuous measurements at 10-min intervals. In the model house, room temperatures were kept constant at 18°C or more. However, in the home, there were large temperature differences between rooms, and in one case, a room temperature in the bedroom was recorded at 6.3°C. In the overall analysis of heart rate and CVRR, there were large individual differences in both absolute values and diurnal variations, and no obvious differences by housing environment. In a detailed analysis focusing on early morning (2 hours after waking), two subjects showed excessive sympathetic activation in the early morning at home, but not in the model house. There was no correlation between this change and salivary amylase. In terms of sleep quality, there were no differences by housing environment. This case of early morning sympathetic activation in a residential setting suggests the importance of the residential setting in the management of early morning hypertension.

Chronotype preference, sleep quality, and night-eating behaviors in patients with metabolic dysfunction-associated steatotic liver disease: Assessing the relationship with disease severity and fibrosis.

Our primary objective is to examine the variance in chronotype, night-eating patterns, and sleep quality in patients with biopsy-proven metabolic dysfunction-associated steatotic liver disease. In addition, we aim to establish a correlation between these variables and the severity of the disease and fibrosis. Patients who were following up with biopsy-proven metabolic dysfunction associated steatotic liver disease (MASLD) were included in the study. Histologically severe disease is characterized by a Steatosis, Activity, and Fibrosis activity score of ≥3 or the presence of advanced fibrosis (≥F3). Participants who met the inclusion criteria were given the Morningness and Evening Questionnaire (MEQ), the Pittsburgh Sleep Quality Index, and the Night Eating Questionnaire to complete. A total of 93 patients were included in this study. According to the MEQ, 48 patients were morning type (51.6%), and 42 (45.2%) were neither type. Sleep quality was determined to be inferior in the non-morningness group (p=0.002). A significantly higher proportion of patients with nocturnal eating syndrome had a non-morningness chronotype preference (n=22, 23.7%), compared to those with a morningness chronotype (n=9, 9.7%) (p=0.001). In the multivariate analysis, both age and poor sleep quality had significant impacts on advanced fibrosis, with odds ratios of 1.11 and 3.81, respectively. Despite the non-morningness chronotype demonstrating poorer sleep quality and a higher prevalence of night-eating behavior, our findings revealed no statistically significant differences in terms of sleep quality, nocturnal eating habits, or chronotype preferences among patients with varying degrees of MASLD severity. On the other hand, advanced fibrosis was significantly impacted by poor sleep quality.

The Effect of Autogenic Training in a Form of Audio Recording on Sleep Quality and Physiological Stress Reactions of University Athletes—Pilot Study

Despite the growing popularity of relaxation training, the effectiveness of an autogenic training (AT) as a method of dealing with sleep problems in group of student athletes is unknown. Therefore, this study aimed to fill this gap. University athletes with decreased sleep quality (selected from 209 participants) were randomly assigned to the experimental (EG, n = 11) and control (CG, n = 11) groups similar in terms of sleep quality, age, gender, type of sport discipline and sport experience. During the 14 days dedicated to performing relaxation training in the form of an audio recording, electronic daily logs and actigraphy were used to monitor the athletes' sleep and daily activity. The EG listened to the recording with suggestions based on AT and CG only to the background music. Pre- and post-measurements of sleep quality by means of the Pittsburg Sleep Quality Index (PSQI) and physiological stress reactions by biofeedback device were performed. In EG and CG, the parameters of sleep and daily activity obtained by actigraphy and daily logs as well as physiological indicators of emotional reactivity did not differ. Sleep quality in PSQI significantly increased after AT usage in EG. AT seems to be an effective method for university athletes in improving subjective sleep quality, but further studies are necessary.

Physiological impacts of social media platforms on adolescent health: a review of key studies and possible directions for future research

There has been rapid growth in the literature surrounding the psychological implications of social media (SM) platforms on adolescent well-being. The physiological effects, however, have not been adequately explored. This review examines the implications of SM on i) neural responses, ii) sleep quality, iii) cellular aging, and iv) the adoption of risky health behaviors, with the overall goal of highlighting novel findings within these domains, identifying gaps in current literature, and providing possible directions for future research. The review was conducted using articles extracted from Google Scholar, PubMed, and NCBI searches. In terms of neural responses, the results demonstrate a decreased activation in the cognitive-control region of the adolescent brain while viewing risky images on SM, however, longitudinal data is required to form causal relationships between SM usage and long-term neurodevelopment. In terms of sleep quality, better insight could be gained if pre-sleep arousal in relation to specific content consumed is analyzed. Increased instances of stress induced due to SM call for the inclusion of this factor when examining markers of cellular aging, as there is no study thus far that has aimed to do so. Lastly, the most direct way in which SM can impact adolescents is through the adoption of risky behaviors being broadcast on these platforms. Analysis of these results suggests that SM platforms hold considerable potential to harm the physiological development of adolescents and warrant further investigation to better understand their full ramifications. Awareness of related issues is important for healthcare professionals and public health organizations.

Changes in the Work Schedule of Nurses Related to the COVID-19 Pandemic and Its Relationship with Sleep and Turnover Intention.

Background: This study aimed to investigate whether different types of changes in the work schedule of nurses working rotating shifts during the COVID-19 pandemic were associated with sleep duration, sleep quality, and turnover intention. Methods: Cross-sectional questionnaire data from 694 nurses participating in the SUrvey of Shift work, Sleep and Health (SUSSH) were collected between the first and the second wave of the COVID-19 pandemic in Norway. A total of 89.9% were female, and mean age was 44.6 years (SD = 8.6 years). Changes in the shift work schedule related to the pandemic comprised reports of more long workdays (>8 h), less days off between work periods, more night shifts, more quick returns (i.e., 11 h or less between two consecutive shifts), more day shifts, and more evening shifts compared to no change in the respective shift characteristics. Change in sleep duration, sleep quality, and turnover intention as well as demographics were also assessed. Logistic regression analyses were performed to investigate whether changes in the specific work schedules were associated with sleep duration, sleep quality, and turnover intention, controlling for sex, age, cohabitation, children living in household, percentage of full time equivalent and other changes in the work schedule. Results: A total of 17% reported experiencing one or more changes in their work schedule during the pandemic. Experiencing any change in the work schedule predicted worse sleep quality (OR = 2.68, p < 0.001), reduced sleep duration (OR = 4.56, p < 0.001), and higher turnover intention (OR = 1.96, p = 0.006) compared to experiencing no change in work schedule. Among the specific changes in work schedules, experiencing an increase in quick returns had the highest odds ratio for worse sleep quality (OR = 10.34, p = 0.007) and higher turnover intention (OR = 8.49, p = 0.014) compared to those who reported no change in quick returns. Nurses experiencing an increase in long workdays were more likely to report higher turnover intention (OR = 4.37, p = 0.003) compared to those experiencing no change in long workdays. Conclusions: Change in work schedule related to the pandemic was associated with worse sleep quality, reduced sleep duration, and higher turnover intention. Increase in quick returns emerged as especially problematic in terms of sleep quality and turnover intention, along with long workdays, which were associated with higher turnover intention.

Research progress in the relationship between sleep during pregnancy and gestational diabetes mellitus

Sleep regulates many body processes, including neuroendocrine immunity. There is increasing evidence that sleep can affect glucose metabolism. Pregnant women are more prone to sleep problems than the general population, and therefore the relationship between sleep during pregnancy and gestational diabetes mellitus is gradually under attention. This paper reviews the associations between sleep during pregnancy and gestational diabetes mellitus in terms of sleep quality, sleep duration, sleep rhythm, and possible biological mechanisms to provide references for preventing and controlling gestational diabetes mellitus.

Associations between obesity and academic enthusiasm and social emotional competence: Moderating effects of gender and sleep quality

ABSTRACT The purpose of this study was to report if there is a difference in obesity according to the gender and sleep quality of primary school students. The participants of this study were 2,607 primary school students in the 4th grade shown in the 2018 (Korean Children and Youth Panel Survey) data. The results of this study are as follows: First, obesity showed a difference according to gender, and there was no difference in terms of sleep quality according to obesity. Second, obesity impacts academic enthusiasm, aggression, and attention of primary school students. In contrast, it was shown that obesity did not impact children’s physical symptoms and self-esteem. Third, according to gender, the associations between obesity and social emotional development and self-esteem were different except for primary school children’s academic enthusiasm, attention, and aggressions. Fourth, sleep quality showed a moderating effect on the social emotional development, including the relationship between obesity and academic enthusiasm and self-esteem.
