The relationship between visual impairment and insomnia among people middle-aged and older in India

The correlation between insomnia and visual impairment has not been extensively studied. This study aims to investigate this relationship among individuals aged 45 and above in India. This investigation utilized data from the 2017–2018 Wave 1 of the Longitudinal Aging Study in India (LASI). Visual impairment was self-reported, including presbyopia, cataracts, glaucoma, myopia, and hyperopia. Insomnia symptoms were determined by at least one of the following: difficulty in initiating sleep (DIS), difficulty in maintaining sleep (DMS), or early morning awakening (EMA) occurring three or more times per week. Analytical methods involved multivariate logistic regression, subgroup analyses, and interaction tests to interpret the data. In our cohort of 65,840 participants, 29.6% reporting insomnia symptoms demonstrated a higher risk for visual impairment. There was a significant association between visual impairment and increased risk of insomnia symptoms after adjustment for confounders. Furthermore, age in the relationship between insomnia and cataracts, sex in the relationship between insomnia and myopia, and age, sex, and smoking status in the relationship between insomnia and hyperopia, was found to have a significant interaction effect, respectively. Visual impairment was significantly associated with a higher incidence of insomnia among middle-aged and older adults in India. These findings underscore the importance of timely interventions to improve sleep quality and overall well-being in visually impaired populations.

Outdoor Artificial Light at Night and Insomnia-Related Social Media Posts

Understanding the outcomes of artificial light at night (ALAN) on insomnia is crucial for public health, particularly in rapidly urbanizing regions. However, evidence of the association between ALAN exposure and insomnia is limited, despite the large number of people exposed to ALAN. To explore the association between outdoor ALAN exposure and insomnia among the Chinese population. This cross-sectional study used social media data from Weibo (Sina), a social media platform, and satellite-derived nighttime light images. The study period spans from May 2022 to April 2023. The study encompasses 336 cities across China's mainland, providing a comprehensive national perspective. Data include insomnia-related posts from the platform users, representing a large and diverse population sample exposed to varying levels of ALAN. Outdoor ALAN exposure (in nanowatts per centimeters squared per steradian [nW/cm2/sr]) was measured using satellite-derived nighttime light images at a spatial resolution of 500 m. The incidence of insomnia among residents at the city level was measured by the number of insomnia-related posts on social media. Multiple linear regression models were used to estimate the association between ALAN exposure and population insomnia, adjusting for population characteristics and meteorological factors at the city level. The study included data from 1 147 583 insomnia-related posts. Daily mean ALAN exposure across the 336 cities ranged from 3.1 to 221.0 nW/cm2/sr. For each 5 nW/cm2/sr increase in ALAN exposure, the incidence of insomnia increased by 0.377% (95% CI, 0.372%-0.382%). The association was greater in less populated cities and under extreme temperature and poor air quality conditions. The observed exposure-response functions between ALAN exposure and insomnia demonstrated an upward trend, with steeper slopes observed at low exposures and leveling off at higher exposures. This study provides evidence of the association between increased ALAN exposure and higher incidence of insomnia. These findings expand the current knowledge on adverse health outcomes of ALAN exposure and emphasize the potential health benefits of well-planned artificial nighttime lighting in China and other developing countries in the early stages of city planning.

Investigation of Depression, Anxiety, Sleep Quality, and Fatigue in Thalassemia Major Patients: A Study of the Correlation Between Sleep Quality and Laboratory Findings.

Thalassemia major (TM) experiences a high rate of psychiatric problems, with frequent occurrences of depression and anxiety as well as a high incidence of insomnia. In the present study, we aimed to investigate the severity of depression, anxiety, sleep disorders, sleep quality, and fatigue and explore the relationship between sleep quality and laboratory parameters. Twenty-eight patients and 37 healthy volunteers were included. Pittsburgh Sleep Quality Index (PSQI), Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), Beck Depression Inventory, Beck Anxiety Inventory, and Fatigue Severity Scale were used. We found 46.43% of TM patients had depression, 78.5% had mild anxiety, and 3.57% had severe anxiety. ISI score (p = 0.027), ISI subthreshold insomnia percentage (p = 0.027), PSQI global score (p = 0.002), PSQI insomnia percentage (p = 0.025), PSQI subjective sleep quality (p = 0.008), PSQI sleep latency (p = 0.003), fatigue score (p = 0.026), and chronic fatigue (p = 0.037) percentage were significantly higher in the patients group than in the controls group. Ferritin was positively correlated with PSQI subjective sleep quality (r = 0.478, p = 0.010) and fatigue score (r = 0.427, p = 0.023). Heart involvement in magnetic resonance imaging was positively correlated with ISI score (r = 0.426, p = 0.024) and ISI classification (r = 0.455, p = 0.015). Depression and anxiety were significantly higher in TM patients compared to healthy controls. Chronic fatigue and insomnia were more common in TM patients, with subjective sleep quality being impaired and sleep latency prolonged. Furthermore, it was observed that individuals with higher ferritin levels had higher scores of subjective sleep quality and fatigue. Additionally, as cardiac involvement increased, severity of insomnia also increased.

The mediating effect of resilience and COVID-19 anxiety on the relationship between social support and insomnia among healthcare workers: a cross-sectional study.

Insomnia in healthcare workers has become a topic of concern in the health system. The high infectivity and longevity of the COVID-19 pandemic have resulted in great pressure and a high incidence of insomnia among healthcare workers. Insomnia among healthcare workers has a negative impact on high-quality healthcare services in addition to their health. Thus, it's necessary to explore insomnia's underlying mechanisms. The present research's aims were threefold: explored the association between social support, resilience, COVID-19 anxiety, and insomnia among healthcare workers during the pandemic, elucidated the underlying mechanism of insomnia, and offered recommendations for improving the health of these workers. A cross-sectional design was adopted. From May 20 to 30, 2022, 1038 healthcare workers were selected to fill out the Oslo 3-item Social Support Scale, the eight-item Athens Insomnia Scale, the Coronavirus Anxiety Scale, and the Brief Resilience Scale. Descriptive statistics and correlations were analyzed by SPSS 25.0. Mediation analysis was conducted by Mplus 8.3 using 5000 bootstrap samples. Of the participating 1038 healthcare workers, the prevalence of insomnia was 41.62% (432/1038). Significant associations were found involving insomnia, resilience, COVID-19 anxiety, and social support. Insomnia was directly affected by social support. Moreover, three indirect pathways explain how social support affected insomnia: resilience's mediating role, COVID-19 anxiety's mediating role, and the chain-mediation role of resilience and COVID-19 anxiety. The results validated our hypotheses and supported the opinion of Spielman etal. 's three-factor model of insomnia. Social support of healthcare workers has an indirect impact on insomnia in addition to its direct one via independent and chain-mediation effects of resilience and COVID-19 anxiety.

The relationship between occupational stressors and insomnia in hospital nurses: The mediating role of psychological capital.

Nurses have a high incidence of insomnia. Insomnia not only damages the physical and mental health of nurses, but also reduces their productivity and quality of care, ultimately affecting patient care. Over the past 30 years, a large number of epidemiological surveys have shown that insomnia in nurses is associated with occupational stress. As an external feature of the role of a nurse, occupational stress is difficult to alter in a short period of time. Therefore, it is necessary to discuss the complex mediating variables in the relationship between occupational stress and insomnia in nurses in order to find different ideas to address the problem of insomnia caused by occupational stress. Psychological capital, the positive psychological strength of an individual, has been widely used in previous reports as a mediating variable between occupational stress and adverse psychological problems. This study aimed to explore the mediating effect of psychological capital on occupational stressors and insomnia among Chinese nurses. The Strengthening the Reporting of Observational Studies in Epidemiology statement was referred to conduct the study. A cross-sectional stratified sampling method was used to recruit 720 participants from a tertiary hospital in Jinan, Shandong province, located in the east of China, from June to August 2019. Questionnaires were used to obtain data on demographic variables, psychological capital, occupational stressors, and insomnia. The study findings revealed that work settings [department (F = 3.08, p = 0.006), working hours per week (t = -2.03, p = 0.043) and shift work (t = 3.66, p < 0.001)], decision latitude (r = -0.25, p < 0.001), psychological job demand (r = 0.15, p < 0.001), social support (r = -0.31, p < 0.001), and psychological capital (r = -0.40, p < 0.001) were differentially associated with insomnia experiences. This cross-sectional survey showed that psychological capital has significant mediation effects on the relationship between occupational stressors and insomnia. In the model of decision latitude - psychological capital - insomnia, the mediating effect was-0.04 (95%CI: -0.07 ~ -0.02), accounting for 50.0% of the total effect; In the model of job demands - psychological capital - insomnia, the mediating effect was 0.03 (95%CI: 0.01 ~ 0.06), accounting for 25.0% of the total effect; In the model of social support - psychological capital - insomnia, the mediating effect was -0.11 (95%CI: -0.16 ~ -0.07), accounting for 39.0% of the total effect. Psychological capital not only had a direct effect on both occupational stressors and insomnia, but also played mediating roles in relationship between occupational stressors and insomnia. It has been suggested that nurses themselves and nursing managers should improve the psychological capital of nurses by various means to alleviate the effects of occupational stress on nurses' insomnia.

Prevalence, risk factors and effects of restless legs syndrome in COPD patients.

Restless legs syndrome (RLS), a sensory motor disorder, is commonly seen amongst chronic obstructive pulmonary disease (COPD) patients. We conducted a study to know its prevalence in COPD and analyse the possible cause and effect of RLS. It is an analytical cross-sectional study conducted between July 2016-December 2020.The prevalence of RLS was evaluated in patients of COPD using RLS diagnostic criteria. Spirometry, iron profile and arterial blood gas analysis was performed in all the patients to evaluate the cause of RLS. The effect was evaluated with diagnostic criteria for insomnia and patient health questionnaire (PHQ2) for depression. There were 205 participants with a mean age of 59±8 years, 182 (88.7%) men and 23 (11.2%) women. The mean body mass index (BMI) was 29±3.9 kg/m2. The prevalence of RLS was 31.2%. RLS was more common amongst women compared to men (60.8% vs 27.4%). RLS was more prevalent among hypoxemic (PaO2<60 mm Hg) and hypercapnic (PaCO2>45 mm Hg) patients (p<0.016; p<0.017). The ROC curve plotted between PaO2 and RLS occurrence showed that the patients having PaO2 less than 76 mm of Hg were more prone to develop RLS. RLS patients had a higher incidence of insomnia as compared to those without RLS (68.8% vs 36.8%, p<0.001). COPD with RLS patients had more depressive symptoms with a higher patient health questionnaire 2 (PHQ2) score (35.9% vs 14.2%, p<0.001) compared to non-RLS COPD patients. The multiple regression analysis also confirmed that RLS led to insomnia and depressive symptoms in COPD patients. To conclude, RLS is common in COPD patients. RLS leads to insomnia and depression, thus should be identified and treated.

An exploration of patient experience of sleep, physical activity, and exercise in early psychosis

ABSTRACT Background Compared to the general population, people with experience of psychosis have poorer physical fitness, higher levels of sedation, lower levels of physical activity, more sleep problems, and higher incidence of insomnia. Methods Thirty-one early intervention psychosis (EIP) service patients took part in an eight-week intervention: provision of a Fitbit, Fitbit software apps, sleep and physical activity guidance, and three discussion sessions with clinicians. Fifteen participants consented to be interviewed, 9 males and 6 females, age range 19–51, average age 29. In-depth interviews investigating patient experiences of sleep and physical activity were conducted. Thematic analysis was employed. Results Patients using an EIP service experience particular issues, problems, and barriers to engaging in effective and healthy sleep and physical activity/exercise; these can have a negative effect on mental and physical health, wellbeing, recovery, and sociability. Patients used factors such as medication, social support, practical strategies, and motivation enhancement to overcome issues, problems, and barriers. Discussion Healthy effective sleep and physical activity/exercise is important to EIP service patients’ wellbeing and mental and physical health. EIP services should consider and assess sleep and physical activity/exercise issues, and promote healthy effective sleep and physical activity/exercise within recovery focused practice.

Effectiveness of a Fitbit Based Sleep and Physical Activity Intervention in an Early Intervention Psychosis (EIP) Service

Purpose: Compared to levels in the general population, people with experiences of psychosis have poorer physical fitness, more sedentary behaviour, lower physical activity, more sleep problems, and a higher incidence of insomnia. The aim of the current study was to examine the feasibility and impact of an intervention with the goal of addressing these issues. Method: Design: intervention with outcome measure data collection, with no control group. Forty-nine early intervention psychosis (EIP) service patients took part in an intervention: provision of a Fitbit, Fitbit software apps, sleep hygiene, and physical activity guidance, and three discussion sessions with clinicians. The sample consisted of 29 males and 20 females, with age range of 17 - 54 years, and average age of 29.5 years. Measures used were Fitbit activity and sleep data, and self-rated Warwick–Edinburgh Mental Wellbeing Scale (WEMWBS) and Positive and Negative Affect Schedule (PANAS). Results: WEMWBS scores significantly improved, with a medium effect size. PANAS negative affect (NA) dropped significantly. Analysis of Fitbit activity and sleep data yielded non-significant results. Conclusion: The intervention was acceptable to EIP patients and is feasible. Improvements in mental wellbeing and negative affect indicate the positive impact of the intervention on mental health. EIP services should consider assessing sleep quality and physical activity/exercise levels, and using this study’s intervention to promote wellbeing and mental health within recovery focused practice. Further research could be undertaken through a sufficiently powered randomised control trial (RCT) comparing this intervention and treatment as usual (TAU).

Effects of Trazodone on Sleep Quality and Cognitive Function in Arteriosclerotic Cerebral Small Vessel Disease Comorbid With Chronic Insomnia.

BackgroundChronic insomnia is common in patients with arteriosclerotic cerebral small vessel disease (CSVD) and aggravates the cognitive impairment caused by CSVD. Low-dose trazodone is effective in treating insomnia, but it is unclear whether it can also improve cognitive function in CSVD patients. This study was performed to explore the effects of trazodone on sleep quality and cognitive function in CSVD comorbid with chronic insomnia.MethodsThis was a randomized, double-blind, placebo-controlled pilot study. Forty patients suffering from arteriosclerotic CSVD and insomnia were recruited from an outpatient clinic. Participants were randomized individually to receive either trazodone (study group) or a placebo (control group) for 4 weeks. The primary outcome was the cognitive score on the Montreal Cognitive Assessment scale (MoCA). Secondary outcomes included sleep parameters measured with polysomnography (PSG) and the Pittsburgh Sleep Quality Index.ResultsTrazodone caused significantly better improvements in concentration and recall abilities, measured with MoCA, as well as in PSG parameters such as sleep efficiency, N3 sleep ratio, and sleep continuity than the placebo, with no significant differences in the occurrence of side effects. The improvement of sleep quality was correlated with increased concentration and recall abilities.ConclusionsA low dose of trazodone seems acceptable and effective in reducing insomnia severity and improving concentration and recall abilities in this pilot study. The improvement of cognition could be achieved by alleviation of insomnia severity. Considering the high incidence of insomnia in CSVD patients, the results of this preliminary study support the use of low-dose trazodone to deal with insomnia and cognitive impairment in CSVD.

Influence of new hire transition workload on insomnia in nurses.

In this study, we investigated the relationship of the prevalence and incidence of insomnia with the new hire transition workload in nurses. This retrospective study used the clinical diagnosis data of the entire nursing population in Taiwan for 2005 to 2008, drawn from the National Health Insurance Research Database. Adjusted logistic regression and Cox regression models were used to separately analyse factors related to the prevalence and incidence of insomnia. During this period, the prevalence of insomnia increased, whereas its incidence remained stable. After adjustment for demographic variables in the logistic regression models, the higher prevalence of insomnia was associated with a longer employment duration and a higher new hire ratio. In the Cox regression models, a higher incidence of insomnia was associated with a shorter employment duration and a higher new hire ratio. Nurses with a longer employment duration had a higher prevalence, but lower incidence, of insomnia. A higher new hire ratio was associated with a higher prevalence and incidence of insomnia. To mitigate the risk of insomnia, we suggest that additional support should be provided to non-new nurses to assist them in the new hire transition.

Restless legs syndrome in hemodialysis patients in Iran.

Restless legs syndrome (RLS) is a common sleep disorder that can present secondary to medical conditions such as renal failure. This study aimed to evaluate RLS frequency and its related factors in chronic renal failure patients treated with hemodialysis. In a cross-sectional design, 163 patients with chronic renal failure were consecutively enrolled from hemodialysis center at Rasool-Akram hospital. Demographics, clinical and laboratory data were recorded. Patients were screened for presence and severity of RLS according to the four International Restless Legs Syndrome Group (IRLSSG) diagnostic criteria and severity scale. Patients with and without RLS were compared using SPSS statistical software (Version 16.0). Sixty-one patients (37.4 %) were diagnosed with RLS. Mean age in RLS group was significantly higher (65.2 ± 9.3 years) than RLS-negative group (59.0 ± 14.7 years; P = 0.004). Serum creatinine level was significantly higher in patients with RLS (7.6 ± 2.1 mg/dl vs. 6.7 ± 1.8 mg/dl; P = 0.009). Glomerular filtration rate in RLS patients was lower than other patients (9.2 ± 3.1 ccs/min vs. 11.6 ± 4.8 ccs/min; P = 0.0001). Patients with RLS had shorter sleep duration, and higher incidence of insomnia, daytime sleepiness, and sedative-hypnotic medication usage (P < 0.05). There was no significant difference between RLS-positive and RLS-negative patients in terms of renal failure pathology, dialysis frequency per week, dose of dialysis, duration of dialysis, renal transplantation, and history of diabetes and hypertension. Hemodialysis patients have a high prevalence of RLS which deserves special attention and specific treatment.

Percepção dos pais sobre hábitos de sono de seus filhos – estudo piloto

Introdução: O sono normal varia ao longo do desenvolvimento humano, sendo uma função biológica fundamental na qualidade de vida do homem. Quando ocorrem distúrbios do sono, esses são, muitas vezes, subdiagnosticados, podendo ser identificados por meio de questionários específicos, que são ferramentas de avaliação autoaplicável, as quais podem identificar sintomas dessa anomalia e possuem baixo custo. Objetivo: Avaliar a percepção dos pais ou responsáveis quanto à existência de eventuais sintomas de distúrbios do sono em seus filhos. Métodos: Foi aplicado o questionário do sono em 65 pais ou responsáveis de crianças com idade entre 2 e 16 anos, atendidas na Clínica de Odontopediatria da Uninove. Resultados: Do total da amostra, 35% apresentaram alguma doença respiratória e dentre os distúrbios do sono encontrados, verificou-se alta incidência de insônia. Conclusão: Constatou-se que a maioria dos pais ou responsáveis, aparentemente, desconhece o que são distúrbios do sono.

The impact of somatic health problems on insomnia in middle age

Objective: The objective of this study is to assess the impact on insomnia symptoms of somatic diseases, psychological factors, living habits and life events during the previous year. Background: Although health problems are a significant cause of insomnia, psychosocial factors are considered to be even more important. The relative impact of these and other factors on insomnia calls for further evaluation. Methods: A questionnaire study in a randomly selected middle-aged population in Finland ( N=626, 264 men and 362 women). Results: In our study, 9.8% of men and 17.0% of women reported the occurrence of insomnia at least once a week during the previous 3 months. Insomniacs perceived their health as ‘poor’ or ‘rather poor’ more often than others and depression, allergic rhinitis, asthma, hypertension and heart symptoms such as arrhythmias were more common among them. Insomnia was not a side-effect of the treatment of these diseases; lack of medical treatment was associated with a higher incidence of insomnia. Work-related factors such as ‘moving to a poorer job or to poorer working conditions’ during the past year increased the possibility of insomnia, while moving house seemed to have a positive effect. When comparing these associations in logistic regression models, nervousness and tension were, however, the factors most significantly associated with insomnia. Conclusions: Psychosocial factors appeared to be more significantly associated with prolonged insomnia than somatic health problems.
