The Effect of Melatonin on Reducing the Frequency and Severity of Migraine Attacks: A Double-Blind, Randomized Clinical Trial.

There is no definite recommendation for melatonin supplementation in episodic migraine. This study aimed to evaluate the effect of melatonin on reducing the frequency and severity of migraine attacks. This randomized, double-blind clinical trial was conducted at Golestan Hospital of Ahvaz, Iran, in 2021. A total of 60 patients with episodic migraine were randomly assigned into 2 groups of receiving 3 mg melatonin (intervention group; n=30) or the same dose of placebo (control group; n=30) along with baseline therapy (propranolol 20 mg, BID) for two months. The attack frequency, attack duration, attack severity (based on VAS), the number of analgesic intakes, drug complications, Migraine Disability Assessment score (MIDAS), and Pittsburgh sleep quality index (PSQI) were evaluated at baseline and in the first, second, third, and fourth months of follow-up. The independent t test, chi-square, and analysis of variance (ANOVA) with repeated measures were used to compare variables between the two groups. In both groups, the frequency, duration, and severity of attacks, taking analgesics, MIDAS, and PSQI scores during follow-up decreased significantly (P<0.001). After treatment, the mean frequency (P=0.032) and duration of attacks (P=0.001), taking analgesic (P<0.001), and MIDAS (P<0.001) and PSQI scores (P<0.001) in the melatonin group were lower than placebo. Only the attack severity was not significantly different between the two groups (P=0.126). Side effects were observed in two patients (6.7%) in the melatonin group and one patient (3.3%) in the placebo group (P>0.999). Our study shows that melatonin was more efficacious than the placebo in the reduction of frequency and duration of migraine attacks. It was equally safe as the placebo and might be effective in the preventive treatment of episodic migraine in adults.Trial Registration Number: IRCT20190107042264N5.

Xiao-Yao-San improves sleep quality in insomnia patients with and without moderate-to-severe obstructive sleep apnea-A pilot polysomnography study

IntroductionThis single-arm pilot study aimed to investigate the effects of a 1-month Xiao-Yao-San (XYS) treatment with on objective and subjective sleep parameters among insomnia patients with and without moderate-to-severe obstructive sleep apnea (OSA). MethodsThis single-arm pre-post study included fourteen participants (average age, 48.2±15.5 years). All participants received XYS (3 g × 3 times/day, after meals) for 28 days. Among them, 7 participants had an apnea-hypopnea index (AHI) ≥15 events/hour and were classified as having moderate-to-severe OSA, while 7 patients had an AHI <15 events/hour. Polysomnography was performed to evaluate the AHI, sleep stage, sleep efficiency, and sleep latency at the beginning and after 28 days of usage. Subjective questionnaires were also administered, including the Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale (HADS-A and HADS-D), and Epworth Sleepiness Scale (ESS). The Wilcoxon test was used to compare the pre-treatment and post-treatment differences. ResultsOur 14 insomnia participants, with an average AHI of 21.2 events/hour at baseline, who were taking XYS, exhibited a statistically significant reduction in PSQI scores (reduction of -3.0; p=0.002) compared to the corresponding baseline values. The objective sleep evaluations did not show differences between participants with or without moderate-to-severe OSA after receiving XYS treatment. For subjective sleep parameters, only participants without moderate-to-severe OSA exhibited statistically significant improvements in sleep quality (PSQI score pretest/posttest: 10.0±3.5/7.0±3.5; p=0.012). ConclusionsXYS treatment may significantly improve sleep quality in participants without moderate-to-severe OSA. Further studies with larger sample sizes and longer durations are needed.

The Effects of Aromatherapy Massage in Menopausal Women With Knee Osteoarthritis: A Randomized Controlled Study

ObjectiveKnee Osteoarthritis (OA)’s prevalence increases during menopause. Aromatherapy massage with different oils is applied in the treatment of knee OA. The aim of this study was to determine the effects of aromatherapy massage with Bergamot essential oil (BEO) on pain, functionality, sleep quality and menopausal symptoms in menopausal women with knee OA. Materials and methodsThis study included 60 menopausal participants diagnosed with grade II-III OA. Participants were randomly divided into three groups: BEO(n=20), placebo(n=20) and control(n=20). The participants in the BEO group, received aromatherapy massage with BEO, in the placebo group aromatherapy massage with sweet almond oil was applied twice a week for 4 weeks. All participants underwent conventional physiotherapy. Visual Analog Scale was used to assess the severity of pain, Osteoarthritis Index to assess functionality, Pittsburgh Sleep Quality Index to assess sleep quality and Menopausal Symptoms Rating Scale to assess menopausal symptoms. All measurements were performed before and after the study. ResultsThe results of the study showed that all three groups were effective on pain, functionality, sleep quality and menopausal symptoms (p<0.001). The results of the study showed that, aromatherapy massage with BEO was found to be more effective on functionality(p<0.001), pain(p<0.001) and menopausal symptoms (somatic and psychological symptoms) (p<0.001) compared to the control and placebo groups. It was determined that aromatherapy massage with BEO did not create a significant difference between the sleep quality scale scores in the control group and the placebo group (p=0.454). ConclusionThis study found that aromatherapy massage with BEO improved functionality, reduced pain and menopausal symptoms, and did not affect sleep quality. We consider that its application in addition to routine treatment may be useful to reduce symptoms.

Assessing sleep quality in elite and junior cyclists.

In the pursuit of optimal recovery, the significance of sleep cannot be overstated for elite cyclists, including high-level cyclists within the junior category. This study aims to assess the sleep quality of elite athletes of different categories and disciplines, including junior. The sleep quality of 112 high-level cyclists (males n = 80; females n = 32) participating in endurance and sprint disciplines was evaluated using the Pittsburgh Sleep Quality Index (PSQI). A noteworthy 41% of both elite and junior cyclists displayed poor sleep quality. No significant differences were observed between elite and junior cyclists in terms of sleep quality, but there was a medium effect size, indicating greater sleep efficiency in junior cyclists [0.36 (0.16, 0.53)]. Gender differences were found, with females exhibiting worse PSQI scores (males = 4.00 [2.25]; females 5.00 [3.00]; p = 0.035). Endurance cyclists spent more time in bed compared to cyclists from sprinting disciplines (8:30 [1.00] and 8:00 [1:03], respectively; p = 0.019). These findings reveal poor sleep habits, even among individuals classified as good sleepers by the PSQI, emphasizing the importance of preventing sleep disorders in cyclists. This study provides valuable insights into athlete sleep quality, encompassing various categories, genders, and cycling disciplines. In conclusion, elite cyclists demonstrate suboptimal sleep quality, suggesting the potential for interventions utilizing the PSQI. These findings advocate for the incorporation of sleep quality assessments into routine evaluations for athletes.

Prediction of Treatment Response and Effect on Clinical Manifestations for Normal Pressure Hydrocephalus of Sleep Related Breathing Disorders

Objectives: Sleep disorders and normal pressure hydrocephalus (NPH) are increasingly important issues observed in neurological disorders. However, the correlation between these diseases has not been sufficiently studied. Thus, we discuss the correlation between sleep disorders and the clinical features of NPH. Methods: Overall, 40 patients with idiopathic NPH were included in the study. To evaluate the sleep disorders and psychiatric problems, surveys were administered, including the 36-Item Short Form Survey, Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISI), Berlin Questionnaire, STOP-Bang Questionnaire, Hospital Anxiety and Depression Scale (HADS), Morningness-Eveningness Questionnaire, and the REM Sleep Behavior Disorder Screening Questionnaire. To evaluate the severity of dementia and ataxia, all of the patients completed the Korean mini-mental state examination; Korea frontal assessment battery score, amd unified Parkinson’s disease rating scale-motor scores before and after cerebrospinal fluid (CSF) drainage. The Pearson’s chi-square test, independent Student’s t-test, Mann–Whitney U test, and linear regression analysis were used to analyze the relationship between sleep disorders and symptom improvement after CSF drainage. Results: Of the 40 patients, 21 patients had poor sleep quality (PSQI&gt;5), 8 patients had insomnia (ISI≥8), 11 patients had daytime sleepiness (ESS≥11), 9 (STOP-Bang≥3) to 13 (Berlin≥2 categories) patients had sleep apnea, 13 patients were anxious (HAS≥8), and 27 patients were depressed (HDS≥8). A linear regression analysis showed that sleep apnea was significantly correlated with cognitive function, and insomnia was correlated with cognitive, motor, and frontal lobe functions. Additionally, patients with severe sleep apnea demonstrated a greater recovery of cognitive function after CSF drainage. Conclusions: Obstructive sleep apnea (OSA) is closely related to the clinical symptoms and treatment effectiveness of NPH. The diagnosis and proper treatment of OSA is expected to improve the prognosis of patients with NPH.

The relationship between sleep quality and depressive symptoms among young adults of India

The study aimed to understand the relationship between Sleep Quality and Depressive symptoms Among Young Adults of India. The data was collected from 310 participants aged between 18 to 27 years through convenience sampling. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), while depressive symptoms were measured using the Beck Depression Inventory (BDI). The analysis revealed a significant positive correlation (r = 0.661, p &lt; 0.001) between PSQI and BDI scores, indicating a meaningful relationship between sleep quality and depressive symptoms. Individuals with poorer sleep quality tended to report higher levels of depressive symptoms, and vice versa. This finding underscores the bidirectional association between sleep disturbances and depression.

Progressive muscle relaxation alleviates anxiety and improves sleep quality among healthcare practitioners in a mobile cabin hospital: a pre-post comparative study in China.

To investigate the anxiety levels, sleep quality and potential risk factors of healthcare practitioners involved in the management of COVID-19 patients in a mobile cabin hospital, and further to assess the impact of progressive muscle relaxation (PMR) on their anxiety levels and sleep quality. We conducted a pre-post self-controlled trial. Healthcare practitioners meeting the inclusion criteria underwent daily 30-min PMR sessions for seven consecutive days. The Pittsburgh Sleep Quality Index (PSQI) and Hamilton Anxiety Scale (HAMA) were used to assess the anxiety and sleep quality of subjects pre- and post-intervention. Statistical analysis was performed using the Wilcoxon test, Mann-Whitney U test, Kruskal-Wallis H test, and Spearman rank correlation. A total of 94 participants completed the study. No statistically significant differences in HAMA or PSQI total scores were observed between groups categorized based on demographic variables such as age, sex, and years of education (p > 0.05). The PSQI total score and its components (excluding sleep medication usage) exhibited a positive correlation with the HAMA total score and its psychological anxiety component (p < 0.05), and a correlation was observed between somatic anxiety manifestations and several components of the PSQI. The PSQI total scores before and after intervention were 10.0 (8.0, 13.0) and 8.0 (6.0, 9.0) respectively (p < 0.001); the HAMA total scores were 8.0 (5.0, 13.0) and 6.0 (4.0, 9.5) respectively (p < 0.001). The detection rates of poor sleep and anxiety states, along with their severity, significantly decreased post-intervention (p < 0.001). Healthcare practitioners experience prominent anxiety and sleep issues in the mobile cabin hospital. PMR can be an effective intervention for improving the anxiety and sleep quality of healthcare professionals during support periods in the mobile cabin hospital. However, trials with larger samples are necessitated to further affirm these preliminary findings.

A mobile app providing individually-tailored psychoeducation about sleep for older adults with chronic health conditions and low health literacy.

This paper reports on a study of a mobile app that provides tailored information about sleep to individuals aged 40 and older who have chronic health conditions and low health literacy. The sleep module was a part of a multitopic app focused on chronic disease self-management. Participants were randomly assigned to receive sleep psychoeducation at reading levels equivalent to 3rd, 6th or 8th grade. The primary outcome measure was the Pittsburgh Sleep Quality Index (PSQI), which was completed at baseline, after the intervention, and again three months later. Outcomes were assessed using repeated measures mixed effects models. Most participants were Black, Indigenous, or Other Persons of Color (BIPOC; 87%); they had average reading level at the 7th grade. Health literacy, socioeconomic status, and number of health conditions were related to the PSQI. The PSQI score decreased over the course of the three study visits for all groups, consistent with a small to medium effect size (d = 0.40). No effect of treatment group was observed. Participants were positive about the usefulness and helpfulness of the app. Results suggest that a brief tailored information intervention may be beneficial for individuals aged 40 and older who have low health literacy and chronic health conditions. Further development of the intervention may enhance its clinical effectiveness.

Association between stressful life events and sleep quality in Chinese university students: Mediating and moderating roles of emotion regulation.

This study investigated whether emotion regulation mediates or modulates the relationship of SLEs with sleep quality and potential sex differences. A total of 1447 Chinese university students completed the Adolescent Self-Rating Life Events Checklist, the Pittsburgh Sleep Quality Index, and the Emotion Regulation Questionnaire. The results indicated that both cognitive reappraisal and expressive suppression significantly mediated and moderated the negative association between SLEs and sleep quality. Additionally, sex differences were found for the mediating role of cognitive reappraisal and for the modulating roles of cognitive reappraisal and expressive suppression in the relationship between SLEs and sleep quality. Although the present cross-sectional data does not allow us to test any causal relationships, these results help clarify the underlying emotion-regulation process between SLEs and sleep in university students and highlight the importance of considering sex differences in emotion regulation.

Sleep Quality and Attentional Function in Adolescent Gamers Aged 13-14 Years in Makassar

The prevalence of adolescents who spend &gt;5 hours per day playing games has a higher risk of developing sleep disorders. Gaming addiction can cause sleep deprivation and the inability to concentrate, which can lead to attention disorders and impulsive behavior. This study is an analytical observational study with a cross-sectional design that aims to determine the relationship of sleep quality in adolescent gamers to impaired attentional function at SMP Negeri 30 Makassar which was conducted in January 2023. The total subject in the study was 64 people. Most of the subject had a duration of playing games of 3-6 hours per day, which totaled 35 (54,6%) people. Gamers who have abnormal sleep quality are 43 (67,2%). We found that the longer duration of gaming caused the sleep quality to decrease (p-value=0,032). There was a significant relationship between the Pittsburgh Sleep Quality Index (PSQI) score with the visual attention test score (p-value=0,001) and the digit span word test score (p-value=0,006). This study concludes that poor sleep quality is associated with impaired attentional function in the accuracy and reaction domain and impaired attentional function in the working memory domain.

Kualitas Tidur dan Hipersomnia Pada Mahasiswa Profesi Ners di Masa Pandemi COVID-19

Background: Poor sleep conditions are common among nursing students, especially those in professional nursing program who have a long duration of clinical practice and direct contact with patients. Various factors have contributed to this condition and the possibility of more severe situation being experienced during the COVID-19 pandemic. Purpose: The study purpose was to identify factors related to sleep quality and hypersomnia among professional nursing students in time of COVID-19 pandemic. Methods: This was a descriptive correlational and cross-sectional design with consecutive sampling on 107 students. The Pittsburgh Sleep Quality Index (PSQI) and the Epworth Sleepiness Scale (ESS) were the questionnaires in this study. Results: Most of respondents experienced poor sleep quality (78,5%) and high normal hypersomnia (36,4%). There were a significant differences of sleep quality based on ethnicity (H(2) = 11,00; p &lt; 0,01). There were a significant differences of hypersomnia based on ethnicity (F = 5,32; p &lt; 0,01) and knowledge of COVID-19 (F = -2,39; p = 0,02). A significant correlation were found between age with sleep duration (r = -0,19; p = 0,04), daytime dysfunction (r = -0,24; p = 0,01), sleep quality (r = -0,23, p = 0,02), and hypersomnia (r = -0,28; p &lt; 0,01). Conclusion: Poor sleep quality and hypersomnia had high prevalences among professional nursing students. Daytime dysfunction was the worst dimension of sleep quality in this study. Students who were younger, Minahasan, and had more knowledge about COVID-19 also had a poorer sleep status.

THE MEDIATING ROLE OF POOR SLEEP QUALITY IN THE RELATIONSHIP BETWEEN POSTTRAUMATIC STRESS DISORDER AND AGGRESSION IN COMBATANTS

Introduction. Stress-related mental disorders pose a significant risk to a patient's social, emotional, and physical well-being. One of the most vulnerable categories of the population to the development of stress-related mental disorders, including post-traumatic stress disorder, in wartime is military personnel who are constantly faced with events that threaten their lives and health. The most common complaints of combatants with PTSD include sleep disturbances and aggression. Therefore, we hypothesized that poor sleep quality may mediate the association between PTSD and aggression in combat veterans. Methods and materials. We conducted a clinical study of 45 combatants, who were divided into the following groups: group 1 (n=24) – combatants with PTSD, and group 2 (n=21) – combatants without stress-related mental disorders. We measured sleep quality by the Pittsburgh Sleep Quality Index and aggression by the Buss-Perry Aggression Questionnaire. Statistical analysis was performed using Jamovi Desktop. The mediation analysis was performed using the medmod 1.1.0 and advanced mediation models 1.0.5. Results. We found a strong statistically significant effect of PTSD on physical aggression (p&lt;0.001). However, the mediating role of sleep was not found (p=0.264), as the effect of sleep disturbance on physical aggression was not confirmed (p=0.257), despite the strong effect of PTSD on sleep disturbance (p&lt;0.001). It was found that the indirect effect of mediation through poor sleep quality accounted for 74.1% of the mediation of the relationship between PTSD and hostility. We established a partial mediation of the relationship between PTSD and aggressiveness by poor sleep quality. The direct effect accounts for 47.6% of the mediation, and the indirect effect through sleep disturbances accounts for 52.4%, which confirms the role of poor sleep quality as a mediator in this model. Concluions. Our findings emphasize that sleep disturbance is a significant symptom of PTSD that can affect other aspects of the disease in combatants. In this study, we demonstrate that poor sleep quality mediates hostility fully and general aggression partially in combatants with PTSD.

Sleep quality and associated factors among undergraduate medical students in Delhi

Background: Sleep disturbances are common among medical students worldwide and affects their health and academic performance. The objective of this study was to assess the quality of sleep in undergraduate medical students of Delhi. Methods: A cross-sectional study was conducted among 234 undergraduate students from medical college in New Delhi. A pre-designed, pre-tested questionnaire was used to collect socio-demographic and life style details and Pittsburgh Sleep Quality Index (PSQI) was used to study the quality of sleep. Data was analyzed by SPSS software version 25.0 and for qualitative data analysis chi-square test was used. Results: Mean age of study subjects was 21.99±1.74 years and males (67.5%) were more as compared to (32.5%) females. Most of the participants 47.4% were in first and second year, 35.5% were from third and final year and 17.1% were interns. Out of 234 participants, only 44% of study participants has good quality of sleep. Most of study participants (56%) were suffering from poor sleep quality. Batch of MBBS, relationship status, BMI and dietary habits of participants were found to be significant predictors of quality of sleep. Conclusions: This study shows that 56% of study participants were suffering from poor quality of sleep. Professionals and medical students who suffer from poor sleep quality have a higher risk of misjudgements, substance abuse, accidents, burnout, anxiety, and depression. So, there is a need to improve knowledge regarding importance of good sleep quality among medical students.

Sleep quality as a mediator between family function and life satisfaction among Chinese older adults in nursing home

BackgroundThe life satisfaction of the elderly in nursing home is the focus of social concern.The purpose of this study was to evaluate the effects of family function and sleep quality on life satisfaction among elderly individuals in nursing homes and examine the mediating effect of sleep quality between family function and life satisfaction.MethodsA cross-sectional observational study was conducted .A total of 127 older adults who completed the Life Satisfaction Index A (LSI-A), the Family APGAR Index and the Pittsburgh Sleep Quality Index (PSQI) were recruited from four nursing homes in Chongqing, China.ResultsLife satisfaction was positively correlated with family function (r=0.434, p<0.01) and negatively correlated with PSQI (r = -0.514, p<0.01). PSQI was found to be negatively associated with family function (r=-0.387, p<0.01).Family function had a significant effect on PSQI (path a: β=-0.8459, 95% CI=-1.2029, -0.4889), and PSQI had a significant effect on life satisfaction (path b: β=-0.3916, 95% CI=-0.5407, -0.2425). The total effect (path c) and direct effect (path c') of family function on life satisfaction were significant (β=0.8931, 95% CI=0.5626, 1.2235 and β=0.56181, 95% CI=0.2358, 0.8879, respectively). The coefficient for the indirect effect of family function on life satisfaction through PSQI was statistically significant (β=0.3312, 95% CI=0.1628, 0.5588). PSQI played a partial mediating role between family function and life satisfaction, and PSQI mediated 32.58% of the total effect of family function on life satisfaction.ConclusionsFamily function and sleep quality were significant predictors of elderly people's life satisfaction in nursing homes. Sleep quality partially mediated the relationship between family function and life satisfaction.The interventions focused on promoting family function and improving sleep quality may be more helpful in improving elderly people's life satisfaction in nursing homes.

The Relationship Between Sleep Quality, Sleep Duration, Social Jet Lag and Obesity in Adolescents.

The frequency of obesity and poor sleep quality among adolescents is increasing and causes many chronic problems. The objective was to investigate the correlation between body mass index (BMI), sleep quality, sleep duration and social jet lag (SJL) among adolescents. This study is cross-sectional. A cohort of 416 adolescents, ranging in age from 12 to 18 participated in the study. Adolescents were divided into three groups according to BMI SDS: adolescents with normal weight, adolescents with overweight and adolescents with obesity. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used to determine the sleep quality of the adolescents. The calculation of SJL and sleep-corrected social jet lag (SJLsc) was performed. The mean age of the adolescents was 15.0 ± 2.9 years.There were 222 males (53.4%). SJL and PSQI scores were significantly higher in the adolescents with obesity compared to the adolescents with normal weight and overweight (p < 0.001). An analysis of the relationship between the PSQI and BMI SDS revealed a correlation that was statistically significant (r = 0.667; p < 0.001). Adolescents with obesity reveal poorer sleep quality and a longer duration of SJL compared to adolescents with normal-weight. Moreover, increased SJL was linked to an increase in BMI. Maintaining good sleep quality and less exposure to SJL may help reduce the risk of obesity.

Prediction of half-marathon performance of male recreational marathon runners using nomogram.

Long-distance running is a popular competitive sport. We performed the current research as to develop an easily accessible and applicable model to predict half-marathon performance in male recreational half-marathon runners by nomogram. Male recreational half-marathon runners in Zhejiang Province, China were recruited. A set of literature-based and panel-reviewed questionnaires were used to assess the epidemiological conditions of the recruited runners. Descriptive and binary regression analyses were done for the profiling and identification of predictors related to higher half-marathon performance (completing time ≤ 105min). Participants were assigned to the training set (n = 141) and the testing set (n = 61) randomly. A nomogram was used to visually predict the half-marathon performance, and the receiver operating characteristic (ROC) was used to evaluate the predictive ability of the nomogram. A total of 202 participants (median age: 49 years; higher half-marathon performance: 33.7%) were included. After multivariate analysis, three variables remained as significant predictors: longer monthly running distance [adjusted odds ratio (AOR) = 0.992, 95% confidence interval (CI): 0.988 to 0.996, p < 0.001], faster mean training pace (AOR = 2.151, 95% CI: 1.275 to 3.630, p < 0.001), and better sleep quality [the Pittsburgh Sleep Quality Index (PSQI), AOR = 2.390, 95% CI: 1.164 to 4.907, p = 0.018]. The AUC of the training and testing sets in nomogram were 0.750 and 0.743, respectively. Further ternary and linear regression analyses corroborated the primary findings. This study developed a nomogram with good potential to predict the half-marathon performance of recreational runners. Our results suggest that longer monthly running distance, faster mean training pace and better sleep quality notably contribute to better half-marathon performance.

Ethnic disparities in the prevalence of diabetes and its association with sleep disorder among older adults in rural southwest China.

This study aimed to examine ethnic disparities in the prevalence of diabetes and its association with sleep disorders among the older adults Han and ethnic minority (Bai, Ha Ni, and Dai) population in rural southwest China. A cross-sectional survey of 5,642 was conducted among the rural southwest population aged ≥60 years, consisting of a structured interview and measurement of fasting blood glucose, height, weight, and waist circumference. The Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep quality. The overall prevalence of diabetes and sleep disorder was 10.2% and 40.1%, respectively. Bai participants had the highest prevalence of diabetes (15.9%) and obesity (9.9%)(P < 0.01), while Ha Ni participants had the lowest prevalence of diabetes (5.1%) and obesity (3.4%)(P < 0.01). The highest prevalence of sleep disorder (48.4%) was recorded in Bai participants, while Dai participants had the lowest prevalence of sleep disorder (25.6%)(P < 0.01). In all four studied ethnicities, females had a higher prevalence of sleep disorder than males (P < 0.01), and the prevalence of sleep disorder increased with age (P < 0.01). The results of multivariate logistic regression analysis indicated older adults with sleep disorder had a risk of developing diabetes (P < 0.05). Moreover, the higher educational level, family history of diabetes, and obesity were the main risk factors for diabetes in participants (P < 0.01). There are stark ethnic disparities in the prevalence of diabetes and sleep disorders in southwest China. Future diabetes prevention and control strategies should be tailored to address ethnicity, and improving sleep quality may reduce the prevalence of diabetes.

The Relation of Sleep Characteristics and Cognitive Impairment in Community-Dwelling Middle-aged and Older Adults: Ardakan Cohort Study on Aging (ACSA)

Introduction: The rise in the elderly population has brought attention to mild cognitive impairment (MCI). Sleep disorders also affect many older adults, indicating an important area of research for disturbed sleep and faster brain aging. This population-based study aims to investigate the association of several sleep indicators with cognitive performance. Methods: This cross-sectional study focused on adults over 50 in the Ardakan Cohort Study on Aging (ACSA). MCI was evaluated using the Mini-Mental State Examination (MMSE) and the Abbreviated Mental Test score (AMTS) in literate and illiterate individuals. Sleep characteristics were collected using the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale, and Berlin questionnaire. The logistic regression models were used to analyze the data. Results: Overall, 3380 literate and 1558 illiterate individuals were included. In both groups, participants with MCI had a significantly higher PSQI global score (p&amp;lt;0.05). Also, among the literate individuals, a significantly higher risk of having sleep-disordered breathing and poor sleep quality was observed in participants with MCI (p&amp;lt;0.05). In illiterate individuals, higher sleep latency than 15 minutes increased odds of MCI (p&amp;lt;0.05). However, after adjusting for all variables, only literate individuals with a sleep duration of more than eight hours had 66 percent increased odds of having MCI (p=0.033). Conclusion: Sleep duration might be associated with cognitive function in the older Iranian population. Our findings underscore the importance of considering sleep patterns in relation to cognitive health.

The Relationship Between Post-Earthquake Anxiety Status with Sleep Problems, Low Back and Neck Pain in Victims of the Kahramanmaraş-Centred Earthquakes

Background: This study aims to examine the relationship between the post-earthquake anxiety status of victims of the Kahramanmaraş-centered earthquake and sleep problems, low back and neck pain. Materials and Methods: Individuals with a mean age of 27.9±9.1 years who experienced the Kahramanmaraş-centered earthquake were included in the study. The individuals included in the study was evaluated with the Beck Anxiety Inventory (BAI), the Oswestry Disability Index (ODI), the Neck Disability Index (NDI), and the Pittsburgh Sleep Quality Index (PSQI). Results: Of the participants, 67% were determined to have mild, moderate, and severe anxiety, and all of them had poor sleep quality (6.9±3.8). While the mean PSQI score of 57% of the participants sheltered in their own homes was 5 and above, this rate was 75% for those sheltered outside their homes. Of the individuals sheltered in their own homes, 27% and 37% of those sheltered outside their own homes had the ODI score percentages above 20%. A statistically moderate correlation was determined between the BAI score and the ODI score, the NDI score, and the PSQI score (r=0.511, r=0.604, r=0.539, respectively). Conclusions: Post-earthquake anxiety was revealed to be associated with sleep problems and low back and neck pain. Considering the relationship between the presence of anxiety, sleep problems, low back and neck pain in the support approaches to be adopted toward earthquake victims, approaches involving these parameters should be planned.
