This study aimed to analyze the influence of workload and burnout on nurses’ sleep quality while controlling for age, gender, and education as potential confounding variables. A quantitative analytic study with a cross-sectional design was conducted among 156 nurses working in a private hospital in Depok City. Data were collected using a workload questionnaire, the Maslach Burnout Inventory (MBI), and the Pittsburgh Sleep Quality Index (PSQI). The data were analyzed using Chi-Square tests and multiple logistic regression. The findings showed that both workload and burnout had significant effects on sleep quality (p < 0.05), with burnout identified as the most dominant factor. Age and gender were also significantly associated with sleep quality, whereas education did not show a statistically significant effect. The regression model demonstrated excellent fit, indicated by a McFadden pseudo R² value of 0.908. These results suggest that occupational factors, particularly burnout, play an important role in determining nurses’ sleep quality. Therefore, effective stress reduction and workload management strategies are needed to support nurses’ well-being and improve sleep quality.

Sleep duration and sleep quality are essential physiological needs that play a significant role in the emotional and behavioral development of children aged 3–6 years. Adequate sleep supports brain development, cognitive functioning, emotional regulation, and social interaction skills in early childhood. Conversely, poor sleep duration and low sleep quality may negatively affect children’s attention, mood stability, and ability to interact socially with peers and caregivers. This article is a literature review using a systematic review approach that analyzes 10 scientific articles published between 2016–2026 to evaluate the relationship between sleep duration and sleep quality with emotional and behavioral problems in preschool children. The article selection process followed the PRISMA flow diagram, with articles sourced from Google Scholar, PubMed, and ScienceDirect databases. The findings consistently indicate that inadequate sleep duration and poor sleep quality are associated with increased emotional and behavioral problems, including hyperactivity, anxiety, emotional dysregulation, and difficulties in social interaction among children. Furthermore, sleep disturbances were found to negatively influence children’s emotional self-regulation abilities, which are crucial for adaptive behavior. Therefore, ensuring adequate sleep duration and improving sleep quality are important strategies to support optimal emotional and behavioral development in preschool-aged children.

Old age is the final phase in the human life cycle, characterised by a decline in physiological function. Global data shows that the prevalence of old age will increase from 33.69 million to 48.19 million by 2035. One of the effects of this decline in physiological function is a disruption in the quality of sleep among the elderly. As many as 50-60% of elderly people in Indonesia experience sleep disorders. One way to overcome sleep disorders is through relaxation therapy. Progressive Muscle Relaxation is a technique performed by stretching and relaxing certain muscles to relax the body. The purpose of this study was to determine the effectiveness of progressive muscle relaxation on the quality of sleep in elderly people. This research method involved a nursing care process from assessment to evaluation using a case study design. The research sample consisted of one elderly person with moderate sleep quality. The intervention was given for 10-15 minutes using eight movements with a frequency of twice a week for one month. The data were analysed using pre-test and post-test PSQI questionnaires to determine sleep quality. The results of this study indicate that progressive muscle relaxation training has an effect on improving sleep quality in the elderly.

Anxiety disorders are common mental health problems among adolescents, particularly high school students who face academic demands, social pressure, and emotional changes. Family support, sleep quality, and academic stress are considered factors related to students’ anxiety levels. This study aimed to examine the relationship between family support, sleep quality, academic stress, and anxiety disorders among students of SMAN 1 Sumbawa Besar. An analytical study with a cross-sectional design was conducted involving 114 students selected through stratified random sampling. Data were collected using the Perceived Social Support–Family (PSS-Fa), Pittsburgh Sleep Quality Index (PSQI), Educational Stress Scale for Adolescence (ESSA), and Depression Anxiety Stress Scale (DASS-42). Bivariate analysis was performed using the chi-square test, while multivariate analysis employed binary logistic regression. Bivariate results indicated significant associations between family support, sleep quality, academic stress, and anxiety disorders (p < 0.05). However, multivariate analysis revealed that only family support and sleep quality were significantly associated with anxiety disorders, while academic stress was not significant after controlling for other variables. These findings suggest that anxiety prevention efforts should prioritize strengthening family support and improving sleep quality, alongside academic stress management within the school environment.

Hypertension is one of the most common health problems among the elderly and has the potential to cause serious complications such as heart disease and stroke. Dietary patterns and lifestyle factors are known to play an important role in increasing blood pressure, particularly fat intake and sleep quality. This study aimed to analyze the relationship between fat intake and sleep quality with the incidence of hypertension among elderly individuals in the coastal area of Tuban District. This study used an analytical observational design with a case-control approach. The total number of respondents in this study was 136 elderly individuals, consisting of 68 cases (elderly with hypertension) and 68 controls (elderly without hypertension). Data on fat intake were obtained using a 24-hour food recall method, while sleep quality was measured using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Data were analyzed using the Pearson Chi-Square test with a significance level of α ≤ 0.05. The results showed that there were significant relationships between fat intake (p = 0.000) and sleep quality (p = 0.000) with the incidence of hypertension among the elderly in the coastal area of Tuban District. Elderly individuals with high fat intake and poor sleep quality were more frequently found in the hypertension group compared to the non-hypertension group. In conclusion, fat intake and sleep quality are associated with the occurrence of hypertension among the elderly. Hypertension control efforts can be carried out through limiting fat intake and maintaining good sleep quality.

Sleep is a fundamental biological need for adolescents and plays a crucial role in supporting cognitive function, emotional regulation, and overall mental health. Despite its importance, sleep quality among adolescents has increasingly declined due to the interaction of individual characteristics, social environments, and daily sleep behaviors. This article aims to analyze the factors influencing adolescent sleep quality using the Social Cognitive Theory framework through a literature review of national and international journals published between 2021 and 2025. The findings show that adolescent sleep quality is shaped by personal factors, including attitudes toward sleep, self-efficacy, and psychological conditions. Environmental factors, such as parental support, peer influence, and academic demands, also significantly affect sleep patterns. In addition, behavioral factors, particularly sleep hygiene practices, play a key role in determining sleep quality. Consistently, unhealthy sleep behaviors are associated with poor sleep quality. Therefore, comprehensive interventions are needed, involving the improvement of sleep habits, strengthening adolescents’ self-regulation abilities, and enhancing family and school support to promote better sleep quality.

Sleep quality is a crucial component of health and overall well-being among older adults, as the aging process is commonly associated with various physiological, psychological, and environmental changes that may significantly disrupt normal sleep patterns. Declining bodily functions, increased health problems, and changes in daily routines often contribute to sleep disturbances in later life. This literature review aims to analyze the factors influencing sleep quality in the elderly by synthesizing findings from relevant national and international studies published in recent years. Various factors were identified, including physiological conditions such as chronic diseases, pain, and hormonal changes; psychological factors such as anxiety, depression, stress, and cognitive decline; lifestyle-related factors such as levels of physical activity, dietary habits, medication use, and caffeine consumption; and environmental aspects including noise exposure, lighting conditions, temperature, and overall bedroom comfort. The reviewed literature consistently indicates that poor sleep quality is strongly associated with impaired physical health, reduced cognitive function, increased fatigue, and decreased emotional well-being in older adults. This review highlights the importance of comprehensive, multidisciplinary interventions that address both intrinsic and extrinsic determinants of sleep to effectively improve overall sleep quality among elderly populations.

Background: Sleep disorders in adolescents are a significant health problem, with a global prevalence reaching 57.8% and particularly high rates in several cities in Indonesia. Poor sleep quality negatively impacts physical health, such as the risk of cardiovascular disease and anemia, as well as mental and cognitive health. Sleep behavior is influenced by a dynamic interaction between personal and environmental factors, as explained in Social Cognitive Theory (SCT). Research Objective: To identify the determinants of sleep deprivation in adolescents, specifically individual and environmental factors, based on a Social Cognitive Theory (SCT) perspective through a literature review from 2019 to 2025. Method: This study utilized a literature review. To obtain research data, the authors searched for scientific articles through Google Scholar, PubMed, and ScienceDirect databases, then analyzed 10 articles that met the inclusion criteria, published between 2020 and 2025. Results: Factors significantly associated with adolescent sleep quality were identified, with individual factors being the most dominant determinant (found in 7 studies), including academic stress and smartphone addiction. Furthermore, a positive association was found with environmental factors (found in 4 studies), such as bright lighting, noise, and uncomfortable room temperature. Conclusion: Within the framework of Social Cognitive Theory, adolescent sleep quality is the result of a reciprocal interaction between personal factors (perceived stress and self-control over gadgets), the physical environment, and sleep behavior. Individual factors such as stress and nighttime gadget use reduce self-efficacy for regular sleep, which is exacerbated by an unfavorable environment.

Anxiety is an excessive state of tension characterized by feelings due to a response to stress or conflicting conditions. This study aims to investigate the relationship between anxiety disorders and sleep quality among nursing students during the Objective Structured Clinical Examination (OSCE) in the Diploma III Nursing Program, Faculty of Health Sciences, Abulyatama University. This study consisted of 168 individuals. The sample was 65 respondents selected using a purposive sampling technique. The research was conducted from July 25th to 29th, 2025. This study employed a descriptive analytical method with a cross-sectional approach. The research instruments were the Zung Self-Rating Anxiety Scale (ZSAS) and the Pittsburgh Sleep Quality Index (PSQI). The data was analyzed using the Chi-Square test. The research results indicated a significant relationship between anxiety disorders and the sleep quality of students during the OSCE at the Diploma III Nursing Program, Abulyatama University, with a p-value of 0.025 (p < 0.05). Based on this finding, this study proves a relationship between anxiety disorders and sleep quality among the Diploma III students during the OSCE preparation. This study suggests that students and the university provide counselling sessions before the test to reduce the effects of anxiety disorders in students. Therefore, this study serves as a resource to raise awareness on how to manage emotions during exam preparation.

Cognitive concentration constitutes a pivotal determinant within the educational process; when an individual exhibits impaired attentional capacity, the instructional input received is unlikely to be effectively encoded into neural pathways or long-term memory, thereby rendering the expenditure of effort, time, and resources essentially futile. This investigation sought to elucidate the associative dynamics among breakfast consumption patterns, levels of physical activity, and sleep quality in relation to academic concentration among students in Grades X and XI within the North Bogor District. Employing a cross-sectional methodological framework, the study encompassed 101 participants whose selection adhered to an observational analytic approach. Empirical data pertaining to breakfast behavior, physical activity, sleep quality, and concentration performance were acquired through standardized self-administered questionnaires. Analytical procedures were conducted using the chi-square statistical test. The inferential findings demonstrated a statistically significant association between breakfast habits (p = 0.002) and sleep quality (p = 0.008) with learning concentration, whereas physical activity exhibited no significant correlation (p = 0.831). Accordingly, the study substantiates that breakfast regularity and sleep quality are meaningfully interrelated with students’ concentration levels, while physical activity does not manifest a measurable relationship with concentration outcomes

Blood transfusion requires the availability of high-quality blood, which is determined, among others, by the donor's hemoglobin (Hb) level. One factor that may affect Hb is sleep quality. Objective: This study aims to determine the relationship between sleep quality and hemoglobin levels among prospective blood donors at UDD PMI South Sulawesi Province in 2025. Methods: An observational analytic study with a cross-sectional design was conducted involving 100 respondents selected using purposive sampling. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI), while Hb levels were measured using a hemoglobinometer. Data analysis was performed using the Chi-Square test with a significance level of p ≤ 0.05. Results: The majority of respondents (75%) had good sleep quality, while 25% had poor sleep quality. Normal Hb levels (12.5–17 g/dL) were found in 96% of respondents, while 3% were low and 1% were high. The Chi-Square test showed a significant relationship between sleep quality and Hb levels (p = 0.050). Conclusion: Good sleep quality is significantly associated with normal hemoglobin levels in prospective donors. Educational programs about healthy sleep patterns before donation are necessary to improve donor eligibility and ensure a safe blood supply.

Aging is often accompanied by sleep problems that have a negative impact on the well-being of older adults, such as reducing their quality of daily life and triggering a higher risk of chronic diseases, depression, and cognitive decline. To address this issue, the physiotherapy team held an educational program at the Arjosari Village ILP in Malang City, which aimed to equip older adults with knowledge about the value of quality sleep. The material was delivered through simple brochures, two-way discussion sessions, and assessments through initial and final tests. A total of 15 people participated, and from the opening discussion, about 80 percent of them admitted to having frequent sleep disturbances. Before the event, a survey showed that their understanding was still minimal, especially regarding what healthy sleep is, the triggers of sleep disturbances, the benefits of good sleep, the signs of sleep disturbances, and steps to overcome them. After the counseling, there was a significant increase, with the level of understanding reaching more than 86 percent on all topics. These results prove that community-based educational approaches such as this are very effective as a means of empowerment and early prevention. Activities such as this should be made a routine to support the overall health of the elderly.

Based on the analysis of the coefficient of determination, it was found that the sleep quality variable contributes effectively to the peak performance variable by 17.9%, while the remaining 82.1% comes from other factors not studied in this research.

Anxiety in patients undergoing preoperative vitrectomy can have a significant impact on biological, psychological, social, and spiritual aspects, manifesting as increased blood pressure, pulse rate, respiratory rate, and sleep quality disturbances that can affect physiological and psychological balance. Blood pressure is influenced by the autonomic nervous system, making anxiety and sleep quality important factors related to cardiovascular stability. This study aims to explain the relationship between sleep quality and anxiety with blood pressure in preoperative vitrectomy patients. The research design used was a cross-sectional correlation study involving 108 respondents. The instruments used included the Pittsburgh Sleep Quality Index (PSQI) to assess sleep quality, the Zung Self-Rating Anxiety Scale (ZSAS) to assess anxiety, and blood pressure measurements before surgery. The analysis used the Spearman test. The results showed that most respondents were in the early elderly age category (34.3%), had a high school education (54.6%), and were employed (57.4%). Most experienced mild sleep disturbances (81.5%) and mild anxiety. The average systolic blood pressure of respondents was 133.50 mmHg (SD 11.569) and diastolic blood pressure was 84.29 mmHg (SD 11.081). Spearman's test showed a relationship between sleep quality and systolic blood pressure (r=0.237; p=0.014) and diastolic blood pressure (r=0.428; p=0.001), as well as between anxiety and systolic blood pressure (r=0.502; p=0.001) and diastolic blood pressure (r=0.326; p=0.001). It was concluded that there was a relationship between sleep quality and anxiety with the blood pressure of patients undergoing preoperative vitrectomy. Nurses are advised to conduct early screening and simple interventions to reduce anxiety and improve the sleep quality of patients

Dependence on smartphones, characterized by excessive anxiety when unable to access them, known as Nomophobia, has become a common problem among students aged 18 to 24 years. One significant consequence of this condition is a decline in sleep quality. This study aimed to examine the correlation between the level of Nomophobia and the degree of sleep quality among third-year students of the Diploma Three Nursing Study Program at Abulyatama University. The research employed a correlative descriptive design with a cross-sectional survey method. Out of 177 third-year students, 64 participants were selected as samples using proportional random sampling. The Nomophobia Questionnaire (NMP-Q) was used to assess the level of Nomophobia, while the Pittsburgh Sleep Quality Index (PSQI) was utilized to measure sleep quality. Data collection occurred at the Diploma Three Nursing Study Program, Faculty of Health Sciences, Abulyatama University, from May 7 to 30, 2025.
