The relationship between hours in bed to examination scores of first year osteopathic medical students

Medical students frequently encounter high levels of stress and pressure, which can negatively affect their mental health and sleep quality, a key determinant of cognitive function and academic success. This study assesses the relationship between hours spent in bed to academic performance among medical students. An observational, cross-sectional survey took place at A.T. Still University - School of Osteopathic Medicine in Arizona (ATSU-SOMA), involving participants from the 2027 cohort. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used and exam scores from the second exam of the fourth block were analyzed. For the purpose of our inquiry, the “Hours in Bed” component score of the PSQI was used for our analysis. The results indicated a significant relationship between sleep effectiveness and exam performance (R² = 0.071, p =4.6×10-48), demonstrating that increased hours in bed was associated with higher exam performance. This research does not address the many other factors that likely play an important role in a student’s academic success. Future studies should investigate the long-term effects of sleep deprivation and explore interventions beyond sleep hygiene, including stress and time management strategies. Understanding the broader impact of sleep on medical education is essential for fostering better outcomes for students in both academic and clinical settings.

Oxytocin Receptor Polymorphism Is Associated With Sleep Apnea Symptoms

Abstract Context Oxytocin supplementation improves obstructive sleep apnea (OSA), and animal studies suggest involvement of oxytocin in respiratory control. However, the relationship between endogenous oxytocin signaling and human sleep status remains undetermined. Objective In this study, we approached the contribution of the intrinsic oxytocin-oxytocin receptor (OXTR) system to OSA by genetic association analysis. Methods We analyzed the relationship between OXTR gene polymorphisms and sleep parameters using questionnaire data and sleep measurements in 305 Japanese participants. OSA symptoms were assessed in 225 of these individuals. Results The OXTR rs2254298 A allele was more frequent in those with OSA symptoms than in those without (P = .0087). Although total scores on the Pittsburgh Sleep Quality Index questionnaire did not differ between the genotypes, breathlessness and snoring symptoms associated with OSA were significantly more frequent in individuals with rs2254298 A genotype (P = .00045 and P = .0089 for recessive models, respectively) than the G genotype. A multivariable analysis confirmed these genotype-phenotype associations even after adjusting for age, sex, and body mass index in a sensitivity analysis. Furthermore, objective sleep efficiency measured by actigraph was not significantly different between genotypes; however, subjective sleep efficiency was significantly lower in the rs2254298 A genotype (P = .013) compared with the G genotype. The frequency of the A allele is higher in East Asians, which may contribute to their lean OSA phenotype. Conclusion The OXTR gene may contribute to OSA symptoms via the respiratory control system, although it could be in linkage disequilibrium with a true causal gene.

Sleep quality and associated factors in adults living in the southern Brazil: A population-based study

ObjectiveTo analyze sleep quality and associated socio-demographic and lifestyle factors in participants from a city originally colonised by Germans in southern Brazil. MethodsA cross-sectional population-based study of 2333 individuals aged 20 to 79 years. Data was collected by interview using a structured questionnaire. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The prevalence of poor sleep quality (PSQI score five or more) was estimated and the associations with study variables were measured by crude and adjusted prevalence ratios using Poisson regression. Resultsparticipants were mostly women (50.9 %), with an average age of 43.3 years. The median total PSQI score was 4 (IQ = 3-7). The frequency of poor sleep quality was 32.7 % (95 % CI 30.7-34.4), higher in older adults (44.0 % vs 30.7 %; p<0.001) and women (40.0 % vs 25.2 %; p<0.001). Multivariate analysis showed that women (PR = 1.3; 95%CI 1.1- 1.5; p<0.001), former smokers (PR = 1.2; 95%CI 1.0-1.4; p = 0.014), current smokers (PR = 1.3; 95%CI 1.1-1.5; p = 0.006), depression (PR = 1.5; 95%CI 1.3-1.7; p<0.001), taking 5 or more medications (PR = 1.2; 95%CI 1.1-1.4; p = 0.001), self-perceived fair health (PR = 2.1; 95%CI 1.8-2.4; p<0.001) or poor/very poor health (PR = 2.6; 95%CI 2.1-3.1; p<0.001) were risk factors for poor sleep quality. Germanic culture (PR = 0.8; 95%CI 0.7-0.9; p<0.001), high school (PR = 0.8; 95%CI 0.6–1.0; p = 0.046) or elementary school (PR = 0.7; 95%CI 0.6-1.0; p = 0.025) or being at work (RP = 0.8; 95%CI 0.7-0.9; p = 0.002) were inversely associated with poor sleep quality. ConclusionsWomen, older adults and some clinical, social, cultural and behavioural conditions are associated with poor sleep quality.

Correlates of perceived stress with anxiety symptoms sleep quality and academic performance among Moroccan students

IntroductionThe main objective of this study was to verify the association of perceived stress with anxiety, sleep quality, and academic performance among Moroccan medical students. MethodsThis cross-sectional study included 222 students enrolled at the Faculty of Medicine and Pharmacy of Fez in Morocco. An online self-administrated questionnaire, for the sociodemographic characteristics, Perceived Stress Scale (PSS-10), Test Anxiety Scale, and Pittsburgh Sleep Quality Index questionnaire were used for the assessment. A descriptive and correlational design was used in this investigation. ResultsOne hundred and thirty-two students completed the survey. A high level of stress was found. A significant positive correlation was observed between the stress level among our population and their levels of anxiety. Stress was also positively correlated with the decrease of students’ sleep quality and academic performance. ConclusionThe results of this investigation present worthy data that highlight the need for this subset of students to anti-stress programs that must be integrated into their curriculum to help them to better manage this psychological issue.

The Correlation between Sleep Quality and Acne vulgaris Incidence in Medical Students of Universitas Tarumanagara

Background: Acne vulgaris is still occurred among medical students worldwide, with a prevalence range of 34,38% to 97,9%. Acne vulgaris, which affects the pilosebaceous unit, is suspected to be related to sleep quality because it involves many hormones, including melatonin, which is associated to sleep. Melatonin can suppress androgens, which play a crucial role in Acne vulgaris pathogenesis. Besides, some studies said that melatonin has a role to suppress inflammation. Medical students also often experience poor sleep quality. Previous studies on the correlation between sleep quality and Acne vulgaris have shown varied results. Objective: This research was conducted to confirm the correlation between sleep quality and Acne vulgaris. Methods: A total of 195 medical students from Tarumanagara University classes of 2021 and 2022 participated in this study by answering the Pittsburgh Sleep Quality Index (PSQI) and Acne vulgaris questionnaires. Samples were taken using non-random consecutive sampling. This research used an analytical observational method with a cross-sectional design. Results: The study found that 92 respondents (47,2%) had good sleep quality, while 103 respondents had poor sleep quality (52,8%). A total of 123 respondents (63,15) experiences Acne vulgaris. Chi-square statistical analysis using SPSS software showed a significant correlation between sleep quality and Acne vulgaris (p-value &lt;0,05; PRR = 1,261; 95% CI = 1,261-1,576). Conclusion: Poor sleep quality can increase the risk of developing Acne vulgaris.

The effect of sleep effectiveness on examination scores of first year osteopathic medical students

Medical students frequently encounter high levels of stress and pressure, which can negatively affect their mental health and sleep quality, a key determinant of cognitive function and academic success. This study assesses the relationship between sleep effectiveness and academic performance among medical students. An observational, cross-sectional survey took place at A.T. Still University - School of Osteopathic Medicine in Arizona (ATSU-SOMA), involving participants from the 2027 cohort. The Pittsburgh Sleep Quality Index (PSQI) questionnaire was used and exam scores from the second exam of the fourth block were analyzed. For the purpose of our inquiry, the “Sleep Effectiveness” component score of the PSQI was used for our analysis. The results indicated a significant inverse relationship between sleep effectiveness and exam performance (R² = 0.087, p =0.000262), demonstrating that increased sleep effectiveness was associated with lower exam performance. The study highlights the sheer amounts of confounding variables in the preconceived notion that “,Sleep is the key for academic success.” This research suggests that academic performance is best explained by multiple variables rather than simply one. Future studies should investigate the long-term effects of sleep deprivation and explore interventions beyond sleep hygiene, including stress and time management strategies. Understanding the broader impact of sleep on medical education is essential for fostering better outcomes for students in both academic and clinical settings.

Endothelial dysfunction in acute coronary syndrome: a complex association with cardiovascular risk factors, sleep quality and cardiorespiratory capacity

Abstract Introduction It is widely acknowledged that normal endothelial function plays a pivotal role in conferring cardioprotective effects against ischemia-reperfusion injury following acute myocardial infarction (AMI) treated by a primary percutaneous coronary intervention (PCI), thereby limiting infarct size (1). However, endothelial dysfunction (ED) has been extensively documented in patients with cardiovascular (CV) risk factors (2). This study proposes a novel perspective, positing that ED could be intricately linked not only with traditional CV risk factors, but also it can be associated with poor sleep quality. Consequently, this interplay might significantly contribute to the attenuation of exercise capacity. Objective The aim of this study was to assess endothelial function following AMI treated with a PCI and investigate the link between endothelial function, CV risk factors, sleep quality and exercise capacity. Furthermore, the study aimed to determine if endothelial function could serve as a predictive factor for future major adverse acute cardiac events (MAACE) following AMI. Materials and methods Sixty-three patients with AMI (56.21 ± 7.6 years) volunteered to participate in this study, . Endothelial function was assessed using the Endothelium Quality Index (EQI) . Sleep quality was evaluated using both actigraphy and the PSQI (Pittsburgh Sleep Quality Index) questionnaire. Exercise capacity was quantified through the 6-minute walking test (6mwt). Results ED was evident, as indicated by an EQI of 1.4 ± 0.7. Furthermore, ED was notably influenced by CV risk factors such as low physical activity level, age, and smoking. A significant correlation was found between EQI and both sleep efficiency (r = 0.340; p = 0.006) and PSQI score (r = -0.533; p &amp;lt; 0.001). Additionally, a strong association was observed between endothelial function and the results of the 6mwt (r = 0.291; p = 0.021). Furthermore, during a follow up period ( near 4 months) following PCI, MAACE were observed in patients with severe ED only. Conclusion In summary, findings of this study may emphasize the importance of enhancing sleep quality and advocating for an active lifestyle as modifiable elements to enhance endothelial function, which can be regarded as a prognostic tool subsequent to AMI, ultimately contributing to improved clinical outcomes. Moreover, this study concluded that AMI patients with severe endothelial dysfunction were more likely to develop MAACE.Endothelial Dysfunction after AMIED following AMI : Causes and effect

Hubungan Kualitas Tidur dengan Kejadian Anemia pada Remaja Putri di SMK Batik 2 Surakarta

This study aims to determine the relationship between sleep quality and the incidence of anemia in adolescent girls at SMK Batik 2 Surakarta. The research was conducted using a cross-sectional design. Samples were selected from 9 classes using Proportional Random Sampling and Simple Random Sampling methods to find research subjects who met the inclusion criteria, namely young women aged 15-19 years and not menstruating. The sample size was determined using the Lameshow formula of 60 young women. Sleep quality data was obtained by filling out the Pittsburgh Sleep Quality Index (PSQI) questionnaire and interviews, the incidence of anemia using the Cyanmethemoglobin method was taken by laboratory staff. To test normality, the Kolmogorov-Smirnov test was used. The research hypothesis was tested using Pearson Product Moment. The results of this study show that there is no correlation between sleep quality and the incidence of anemia, the relationship between these two variables is negative, meaning that the worse the sleep quality, the lower the hemoglobin level value.

Impact of switching from EFV/F/TDF to B/F/TAF on psychiatric symptoms and neurocognition.

The aim was to investigate whether switching from EFV/F/TDF to B/F/TAF may improve neuropsychiatrc symptoms and neurocognition. Pilot, single-arm, prospective study of persons with HIV (PWH) on the efficacy and safety of switching from EFV/F/TDF to B/F/TAF. Participants underwent neuropsychological assessment (NPA) at switch (T0) and after 48 weeks (T1). NPA was carried out through a standardized battery of 12 tests. Neurocognitive impairment (NCI) was defined by a score ≥1 standard deviation (SD) below the normal mean on at least 2 tests or ≥2 SD below on 1 test. Individual z-scores were determined, NPZ-12 was calculated as the average of 12 test z-scores and change of NPZ-12 was the outcome. HIV-associated Neurocognitive Disorder (HAND) was classified by Frascati's criteria. Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI-II), and Pittsburgh Sleep Quality Index (PSQI) were administered. Paired-Wilcoxon and McNemar tests were used for comparisons, and logistic regression for associations with NCI changes. Out of 126 participants, BAI, BDI-II, and PSQI questionnaires revealed an improvement at T1. NPA revealed NCI in 40.5% of persons at T0 and 42.1% at T1 (p = 0.746). Specifically, at T0, among participants with NCI, 35% improved; among those without, 26% worsened at T1; NPZ-12 score worsened at T1. 5.6% of ANI was observed at T0 and 7.9% at T1. No factor associated with these changes was found. Our results suggest switching from EFV/F/TDF to B/F/TAF significantly improves psychiatric symptoms and sleep quality. Neurocognitive performance remained stable, although a decline in NPZ-12 and in specific domains was observed.

Compliance with 24 h Movement Behavior Guidelines for Pregnant Women in Saudi Arabia: The Role of Trimester and Maternal Characteristics.

Complying with 24 h movement behavior guidelines for pregnant women may prevent pregnancy complications. This single time point, cross-sectional investigation assessed compliance with the 24 h movement behavior guidelines in pregnant women in Saudi Arabia and examined the role of trimester and maternal characteristics. Pregnant women (n = 935; age = 30 ± 5.6 years; first trimester = 24.1%, second trimester = 33.9%, third trimester = 42.0%) self-reported their characteristics (nationality, region, degree, occupation, smoking status, health status, having children, previous birth). The short-version International Physical Activity Questionnaire, Sedentary Behavior Questionnaire, and Pittsburgh Sleep Quality Index Questionnaire measured moderate physical activity (MPA), sedentary behavior (SB), and sleep duration, respectively. Compliance with the 24 h movement behavior guidelines was reported using frequencies and percentages. Prevalence ratios compared the prevalence of compliance by trimester and maternal characteristics. Approximately half of the participants did not comply with MPA or sleep duration guidelines (n = 524, [56.0%] and n = 424, [45.5%], respectively). In contrast, about two-thirds of participants (n = 648, [69.3%]) adhered to the SB guideline. Only 154 (16.5%) participants complied with all 3 24 h movement behavior guidelines. Pregnant women in their second trimester, living in Al-Ahsa Governorate, and currently smoking with a bachelor's degree were the most likely to comply with the guidelines. These findings underscore the need for tailored efforts to promote healthy 24 h movement behavior guidelines for pregnant women in Saudi Arabia, especially early in pregnancy, while accounting for important maternal characteristics.

Efficacy and safety of auricular acupressure on reduction of estazolam in patients with insomnia: a study protocol for a three-arm, blinded randomized controlled trial

BackgroundDrug-dependent insomnia refers to insomnia patients taking sedatives and sleeping pills regularly for a long period. Auricular acupressure (AA) has attracted growing attention as a complementary treatment for insomnia. Nevertheless, there is a lack of rigorous studies evaluating AA specifically for estazolam-dependent insomnia. Our proposed trial aims to assess the therapeutic effect of AA on estazolam-dependent insomnia.MethodsThis study is a randomized, single-blinded, three-arm controlled trial. No less than 108 participants will be randomized into one of three groups: AA group, sham auricular acupressure (SAA) group, and conventional dosage reduction group. All treatments will be administered for 4 weeks, with a follow-up period of 1 month. The primary clinical outcomes will be estazolam dosing and reduction rates, serum gamma-aminobutyric acid (GABA) and cortisol (CORT) levels. Secondary outcomes will concern the Pittsburgh sleep quality index (PSQI) and Benzodiazepine Withdrawal Symptom Questionnaire (BWSQ). Both intention-to-treat and per-protocol analyses will be performed, with the significance level determined as 5%.DiscussionThe study results will provide evidence on the efficacy and safety of AA in managing estazolam-dependent insomnia by analyzing its immediate effect, time-effect relationship, and reduction of estazolam use.Trial RegistrationClinicaltrials.gov (identification number: NCT06258226; Registered 5 February 2024, https://clinicaltrials.gov/ct2/show/NCT06258226).

8352 Association Between Sleep and Physical Activity Among Women with Obesity and Infertility

Abstract Disclosure: K. Brûlé: None. F. Jean-Denis: None. M. Belan: None. M. Langlois: None. S. Ruchat: None. J. Baillargeon: Grant Recipient; Self; Ferring Pharmaceuticals. BACKGROUND: Infertility affects up to 15% of couples and a major modifiable risk factor is obesity. Thus, it has been recommended that women with obesity should be assisted to adopt healthy lifestyle behaviors prior to conception. Also, individuals with obesity often present reduced sleep quantity and quality, which could affect their physical activity (PA) practice. On the other hand, PA seems to improve sleep quality. Regular practice of PA could also improve an individual’s functional capacity, and thus could be an objective measure of a person's level of PA. Hence, our study aimed to: 1) compare the sleep quantity of women with obesity and infertility to the Canadian population; and 2) determine the relationship between their PA practice, functional capacity and sleep quantity and quality. Methods: This cross-sectional study is nested within a multicenter randomized controlled trial recruiting women of 18-40 years old with obesity and infertility in Canadian fertility clinics. At their initial research visit, they were assessed for body mass index (BMI), functional capacity (distance at 6-min walk test); total energy expenditure (EE, kcal/day), total PA (steps/day) and time spent in light (min/day) or moderate-to-vigorous physical activity (MVPA, min/day) or sedentarity (min/day) (Fitbit monitor); as well as sleep quality and duration (Pittsburgh Sleep Quality Index questionnaire and Fitbit monitor), and total time asleep per night (Fitbit monitor). For the Canadian population, we used the mean sleep duration of women aged 18-60 years reported in the Canadian Community Health Survey of 2020. Associations were tested using Pearson’s correlations (some measures were made normally distributed by square root transformation). Results: A total of 98 women (mean age = 31.5 years and mean BMI = 39.2 kg/m2) from 5 centers were included, 48% of whom were recruited in Sherbrooke (Qc). Their sleep duration was significantly lower than that of Canadian women (7.2±1.1 vs 8.1 h; p&amp;lt;0.001). Poor perceived sleep quality was negatively associated with EE (r=-0.271; p=0.020) and steps (r=-0.280; p=0.026), but directly with sedentary time (r=0.277; p=0.033). Light PA was negatively associated with measured sleep duration (r=-0.241; p=0.016), but positively associated with measured sleep efficiency (r=0.237; p=0.036). Functional capacity is positively associated with measures of EE, steps and MVPA (r=0.239 to 0.347; p=0.005 to 0.031), and there is a tendency with total time asleep (r=0.238, p=0.061). Conclusion: Canadian women with obesity and infertility have, on average, less sleep time than women in the general Canadian population. Their PA practice is associated with better perceived sleep quality but does not improve their sleep quantity per se. Furthermore, the association between their functional capacity and PA practice suggests that it is a valid objective indirect measure of PA practice. Presentation: 6/1/2024

The psychometric properties of the Pearlin Mastery Scale in persons living with restless legs syndrome.

Restless Legs Syndrome (RLS) is a neurological disorder characterized by an urge to move arms and legs, commonly combined with distress, pain and motor restlessness. It can cause fragmented sleep, daytime symptoms, and decreased quality of life. Pharmacological treatment can suppress symptoms, but not cure. When challenged with illness, people may turn to their inner psychological resources such as self-esteem and mastery. The Pearlin Mastery scale was developed to study stress and coping, is commonly used in people with chronic illnesses, however, not yet validated in people with RLS. The aim was to test reliability and construct validity of the Pearlin Mastery Scale in persons with RLS. A cross-sectional postal survey including the Pearlin Mastery Scale, Restless Legs Syndrome-6 Scale, Pittsburgh Sleep Quality Index and Patient Health Questionnaire was sent out to members (n = 1500) of the national RLS association and 788 (52.5%) agreed to participate. Data were analyzed using classical test theory, Confirmatory factor analysis and Rasch measurement theory analysis. Hypothesis testing for construct validity was done by bivariate correlation analyses. Most respondents were women (65%), retired (71%) and had a mean-age of 70.8 years (SD 11.4). The 7-item version of the Pearlin Mastery Scale showed poor fit to the one factor model. After omitting the two positively worded items (i.e., item 4 and 6), the 5-item version was found to be unidimensional, with satisfactory internal consistency. However, all items showed considerable ceiling effects. No measurement variance was seen regarding age-groups or sex. Higher level of mastery was moderately correlated with less depressive symptoms but only weakly correlated to RLS-related sleep problems. The 5-item version of the Pearlin Mastery Scale is suggested to be used in persons with RLS due to its acceptable psychometric properties. The instrument could be applied as an outcome measure for behavioral change interventions aiming to support mastery in RLS.

The Relationship Between Poor Sleep and Memory Impairment Among Shift Nurses in China: A Cross-Sectional Study.

Many shift nurses experience poor sleep quality, and the effect on nurses' cognitive function remains unclear. The study aims to investigate sleep status and explore its association with cognitive function. This descriptive cross-sectional study was conducted in a tertiary care hospital in Fujian, China between March and September 2022. By convenience sampling method, 588 shift nurses participated in this study. The Pittsburgh Sleep Quality Index (PSQI) and Bergen Shift Work Sleep Questionnaire (BSWSQ) were used to assess sleep quality, while the Chinese version of Ascertain Dementia-8 (AD-8) was used to evaluate cognitive function. A PSQI score ≤7 is classified as good sleep quality, and a score >7 indicates poor sleep quality. An AD-8 score≥ 2 is considered indicative of memory impairment. Multivariate logistic regression analysis was conducted to explore the association between sleep status and memory impairment. A total of 310 (52.6%) participants presented poor sleep quality. Among them, 52.2% of participants had day shift-related sleep problems, 45.9% had evening shift-related sleep problems, 61.9% had night shift-related sleep problems, and 15.0% reported rest-day/vacation-related sleep problems. The prevalence of poor sleep quality and each shift-related sleep problem in the memory impairment group were higher than in the normalmemory group (P<0.05). Multivariate logistic regression analysis indicated that poor sleep quality (OR=2.073, 95% CI: 1.398~3.072), evening shift-related sleep problems (OR=1.707, 95% CI: 1.028~2.835), night shift-related sleep problems (OR=1.859, 95% CI:1.104~3.129), and rest-day/vacation-related sleep problems (OR=2.069, 95% CI:1.170~3.659) was significantly associated with memory impairment. This study highlights the prevalence of poor sleep quality among clinical nurses and identifies poor sleep quality and shift-related sleep problems (excluding day shift) as risk factors for memory impairment. Nurse managers should prioritize sleep quality and focus on cognitive function to enhance nurses' occupational health.

DETERMINANT FACTORS OF THE MENSTRUAL CYCLE IN GRADUATE NURSING STUDENTS

According to WHO, more than 75% of women experience menstrual disorders and on average occur at the age of 17-29 years. One of the factors that influence the occurrence of irregular menstrual cycles is poor sleep quality. This study aims to determine the relationship between sleep quality and menstrual cycle in undergraduate nursing students at Harapan Bangsa University. This type of research is an analytic survey with a cross sectional design. The population in this study were 316 undergraduate nursing students and a sample of 174 students with Proportional random sampling method. Instruments used Pittsburgh Sleep Quality Index (PSQI) and menstrual cycle questionnaire. Data analysis used bivariate analysis for frequency distribution and univariate data analysis with chi square to determine the relationship. The results of this study obtained the frequency distribution of sleep quality obtained the highest results (79.3%) in the bad category and the menstrual cycle obtained results (67.8%) in the normal menstrual cycle category, with a p value = 0.151 (p&gt; 0.05). The conclusion is that there is no significant relationship between sleep quality and menstrual cycle in Nursing Study Program Undergraduate Students at Harapan Bangsa University.

The Relationship of Sleep Quality with Severity Level Acne Vulgaris in Students Aged 17-21 Years Faculty of Dentistry Prima Indonesia University

Acne vulgaris is chronic inflammation of the sebaceous glands. Many factors cause acne vulgaris, one of which is sleep quality. Poor sleep quality will cause an increase in androgen hormones which are associated with an increase in the incidence of acne vulgaris. Purpose: This study aims to determine the relationship between sleep quality and the severity of Acne vulgaris in students aged 17-21 years. This research is an analytical observational research with a cross-sectional method and sampling using a purposive sampling method. Research instruments using the Pittsburgh Sleep Quality Index (PSQI) questionnaire and the severity of acne vulgaris using the Lehmann classification. The result showed that of the 70 samples collected, there were 9 men and 61 women. There were 30 people with mild degree acne, 37 people with moderate degree and 3 people with severe degree. Based on sleep quality, there were 24 people with good sleep quality and 46 people with poor sleep quality. The results of Spearman's analytical correlation showed that there was a relationship between sleep quality and the severity of Acne vulgaris (P-value = 0.005). So, it can be concluded that sleep quality is related to the severity of Acne vulgaris in students aged 17-21 years.

Smartphone addiction, sleep quality and musculoskeletal disorders in students

Objective: Smartphone addiction may lead to many health issues. Excessive smartphone usage has been linked to musculoskeletal disorders and sleep problems. We aimed to examine the correlation between smartphone addiction, sleep quality and musculoskeletal disorders. Materials and Methods: 60 university students were included in the study. Individuals' smartphone addiction, sleep quality and musculoskeletal disorders were evaluated with the Smartphone Addiction Scale (SAS), Pittsburgh Sleep Quality Index (PSQI) and Cornell Musculoskeletal Discomfort Questionnaire (CMDQ), respectively. Results: There was a weak correlation between SAS and PSQI’s sleep efficiency, sleep disturbance, daytime dysfunction subscales, PSQI total score, and CMDQ’s lower extremity and spine subscales (p=0.021; p=0.020; p=0.008; p=0.008; p=0.029; p=0.019). There was a well correlation between SAS and CMDQ’s upper extremity subscale and CMDQ total score (p=0.001) Conclusion: It was concluded that as smartphone addiction increases in students, musculoskeletal disorders increase. Smartphone addiction was particularly associated with the neck, shoulder, back, upper arm, wrist and hip regions. It was also concluded that smartphone addiction worsens sleep efficiency, sleep disturbance, daytime dysfunction and general sleep quality.

Hubungan Kualitas Tidur dengan Derajat Keparahan Acne Vulgaris pada Siswa-Siswi Kelas X di Sma Muhammadiyah 2 Bandar Lampung Provinsi Lampung Tahun 2024

Acne vulgaris is a multifactorial chronic skin condition, characterized by inflammation in the pilosebaceous units, such as the formation of comedones, papules, pustules, nodules, and cysts, which typically present on the face, upper body, and upper arms. Sleep quality is defined by an individual's capacity to sleep adequately and achieve the necessary amount of rest. This study aims to identify the correlation between sleep quality and the severity of acne vulgaris among tenth grade students at Muhammadiyah 2 Senior High School of Bandar Lampung, Lampung Province in 2024.The research adopts a quantitative approach and analytical survey method with a cross-sectional design.

The analysis indicates a significant correlation between sleep quality and the severity of acne vulgaris among tenth-grade students at Muhammadiyah 2 Senior High School in Bandar Lampung, Lampung Province in 2024, with a p-value of 0.000 ≤ 0.05. The results of this research provide useful information and may serve as a supplementary resource for future research.

A closer look at depression and sleep quality relation: A cross-sectional study of taxi drivers in Tabriz metropolis.

Taxi drivers play a significant role in urban mobility and safety as professional drivers. They typically have poor incomes, long work hours, lack of sleep, and high levels of stress, which increase the risk of physical and mental illnesses. The goal of this study was to explore the relationship between sleep disorders and depression among Tabriz metropolis taxi drivers. Using the street intercept technique, a cross-sectional study was conducted with the participation of 402 taxi drivers in Tabriz during January and March 2020. Data collection tools included the Pittsburgh Sleep Quality Index (PSQI) and Patient Health Questionnaire as well as demographic information. Twenty taxi stops were used as sampling sites, and the method used was random sampling based on the number of drivers at each stop. Statistical analysis was performed using Stata 13. The majority of drivers worked an average of 6 days each week, with a mean tenure of 13.3 years. The sleep quality mean score for drivers was 5 (SD = 2.3). Approximately, 21% of them had sleep disorder (PSQI >6). Moderate depression was recognized in 13% of drivers and moderately severe depression has been found in 5% of them. Drivers were more likely to experience sleep disorders if they had mild (odds ratio [OR] = 3.9), moderate (OR = 16.4), or fairly severe depression symptoms (OR = 35.3). A seven times higher risk of depression was identified among drivers with sleep disorders. It might be contended that a mutual relationship has been found between sleep disorders and depression, and disregarding this will deteriorate sleep turbulences. Considering the pivotal role of taxi drivers in urban mobility, accommodating initiatives that give a break time for drivers and improve their mental health is recommended.

The relationship between adolescents' physical activity, circadian rhythms, and sleep.

To explore the correlation between physical activity, circadian rhythms, and sleep in adolescents, and analyze the influencing factors of sleep quality in this population. A total of 381 high school students were selected through cluster sampling in a specific high school. The Pittsburgh Sleep Quality Index (PSQI) was employed to categorize the participants into a good sleep quality group (n=199) and a poor sleep quality group (n=182). Comprehensive assessments were conducted using the Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), PSQI, Morningness-Eveningness Questionnaire-5 (MEQ-5), and International Physical Activity Questionnaire Short Form (IPAQ-SF). The prevalence of poor sleep quality is 47.8%. The BMI in the poor sleep quality group is higher than that in the good sleep quality group, and the male ratio is lower than that in the good sleep quality group. The poor sleep quality group exhibits significantly higher levels of depression, anxiety, evening chronotype, and low physical activity compared to the good sleep quality group.Spearman rank correlation analysis revealed a positive correlation between the PSQI total score and HAMA and HAMD scores, and a negative correlation with physical activity and MEQ-5 scores. Binary logistic stepwise regression analysis identified lack of physical activity, eveningness chronotype, anxiety, and depression as risk factors for poor sleep quality. Adolescent sleep quality is correlated with gender, BMI, anxiety, depression, chronotype, and physical activity levels. The findings highlight the importance of considering these factors in interventions aimed at improving sleep health in adolescents.
