Sleep problems and subjective cognitive complaints among middle-aged and older adults in 45 low- and middle-income countries
2022
Background: Currently, a small body of evidence suggests that sleep problems are positively associated with subjective cognitive complaints (SCC). However, no studies on this topic exist from low- and middle-income countries (LMICs). Thus, we investigated the association between sleep problems and SCC in a large sample of middle-age and older adults from 45 LMICs. Methods: Cross-sectional, predominantly nationally representative, community-based data were analyzed from the World Health Survey. Sleep problems (such as difficulties falling asleep, waking up frequently during the night or waking up too early in the morning) in the last 30 days were self-reported. Two questions on subjective me…
Sleep Alterations in Non-demented Older Individuals: The Role of Cortisol
2017
Background: Sleep alterations can impair quality of life and contribute to disease progression but they, and their features and contributing factors, are rarely analysed in institutionalised older individuals. In this study, we investigated sleep alterations, the factors involved, and the role of cortisol in sleep-related problems in institutionalised individuals. Methods: We conducted a descriptive cross-sectional study in participants living in nursing homes in Valencia (Spain); sleep alterations were determined based on two validated tools: the Athens insomnia scale and Oviedo sleep questionnaire. Plasma cortisol was measured in the morning and determined by high performance liquid chrom…
Sleep quality in caregivers of patients with Alzheimer’s disease and Parkinson’s disease and its relationship to quality of life
2012
ABSTRACTBackground: Knowledge about sleep complaints of caregivers of patients with Alzheimer's disease (AD) and Parkinson's disease (PD) is limited, and we lack information about the relationship between caregivers’ sleep problems and their quality of life (QoL).Methods: We evaluated subjective sleep quality and its relationship to QoL in a group of 80 caregivers of patients with AD (ADCG, n = 40) and PD (PDCG, n = 40), and in 150 controls. Information about night-time complaints was collected using the Pittsburgh Sleep Quality Index (PSQI). QoL was measured using the McGill QoL Questionnaire.Results: Eighteen ADCG (45%), 22 PDCG (55%), and 45 (30%) controls reported poor sleep quality. Me…
Sleep and its relationship to health in parents of preterm infants: a scoping review
2018
Background: Sleep is essential for human health and functioning. Parents of preterm infants are susceptible to sleep disturbances because of stress related to the preterm birth. Poor sleep has the potential to affect parental health and well-being. The aim of this study was to identify and map evidence on sleep and its relationship to health in parents of preterm infants. No review has summarized the evidence on this topic. Methods: A scoping review was conducted. Seven health and medical electronic research databases were searched for relevant quantitative and qualitative primary studies, including grey literature. The search was performed March 2–7, 2017. Results: Ten American studies and…
Sleep disorders in advanced cancer patients: prevalence and factors associated.
2003
Sleep disorders have been invariably reported in cancer population. However, the prevalence of this problem in advanced cancer patients has never been assessed. The aim of this study was to evaluate the frequency of sleep disturbances in terms of quantity and quality, and possible associated factors.A consecutive sample of patients admitted to a pain relief and palliative care unit were surveyed. Patients with severe cognitive problems or who were too ill were excluded. Epidemiological and clinical data, including the performance status, habits, relevant symptoms, and drug use were recorded. Patients were asked to answer a small questionnaire regarding their sleep, and duration and characte…
Investigating the relation among disturbed sleep due to social media use, school burnout, and academic performance.
2019
Abstract Introduction Previous studies have revealed the significant influence of electronic devices, especially social media use, on sleep difficulties among adolescents. In this study, disturbed sleep due to social media use (DSSM) was defined as reduced or troubled sleep caused by nighttime-specific behaviors such as waking to check updates, being notified by incoming messages, or postponed bedtime because of social media activities. Inadequate and disturbed sleep during youth interferes with daytime academic efficiency and may be associated with school burnout, which were examined in this study. Methods Using two data waves collected from questionnaires on school burnout and DSSM and sc…
Polysomnographic Findings in Fragile X Syndrome Children with EEG Abnormalities
2019
Fragile X syndrome (FXS) is a genetic syndrome with intellectual disability due to the loss of expression of the FMR1 gene located on chromosome X (Xq27.3). This mutation can suppress the fragile X mental retardation protein (FMRP) with an impact on synaptic functioning and neuronal plasticity. Among associated sign and symptoms of this genetic condition, sleep disturbances have been already described, but few polysomnographic reports in pediatric age have been reported. This multicenter case-control study is aimed at assessing the sleep macrostructure and at analyzing the presence of EEG abnormalities in a cohort of FXS children. We enrolled children with FXS and, as controls, children wit…
Bidirectional relationship between caregiver burden and neuropsychiatric symptoms in patients with Alzheimer's disease: A narrative review
2019
Objective: The aim of this review is to make a state of the art of the potential influence of neuropsychiatric symptoms (NPs) on caregiver stress and vice versa. Methods: We searched PubMed and Google Scholar for potential eligible articles. Results: Patients with Alzheimer's disease (AD) usually need high levels of care in all activities of daily living, most of them provided by family members, friends, or informal caregivers. Caregivers have to cope with both age-related conditions and dementia-related factors. Therefore, caregiving in dementia is more difficult and stressful than caregiving for older adults, affected by other conditions. Neuropsychiatric symptoms, such as anxiety, agitat…
Perceived tiredness among adolescents and its association with sleep habits and use of psychoactive substances
1997
This study investigated the variation in perceived tiredness among 11, 13 and 15-year-old Finnish adolescents (n = 4187). Additionally interrelationships between sleep habits, use of psychoactive substances (alcohol, tobacco and coffee) and perceived tiredness among 15-year-olds were examined. This study is part of an international, WHO-coordinated survey of school children's health and lifestyle (the HBSC Study). In Finland, research data represented the whole country. The data were collected in March-May 1994. Pupils responded anonymously to a standardized questionnaire during a class period. Subjective tiredness was very common and increased with age among adolescents. Perceived tirednes…
Sleep Quality in Patients with Heart Failure in the Spanish Population: A Cross-Sectional Study
2020
Background: Heart failure is a major problem in western societies. Sleep Disorders maintain a bidirectional relationship with heart failure, as shown by studies conducted in other countries. This study aims to describe the quality of sleep in Spanish patients with heart failure. Materials and methods: We carried out a cross-sectional study to analyze the quality of sleep in a sample of 203 patients with a diagnosis of heart failure admitted to an Internal Medicine Service. The Pittsburg Sleep Quality Index (PSQI) was used to evaluate sleep quality in our sample over a one-month period. Results: 75% of the sample presented sleep disorders. The most common problems included the interruption o…
