Although obstructive sleep apnea and cardiovascular disease have common risk factors, epidemiologic studies show that increases risks for independently of individuals' demographic characteristics (i.e., age, sex, race) or markers smoking, alcohol, obesity, diabetes, dyslipidemia, atrial fibrillation, hypertension).Individuals with severe are at increased coronary artery disease, congestive heart failure, stroke.The underlying mechanisms explaining associations between not entirely...
Epidemiologic studies show a curvilinear relationship between inadequate sleep (< 7 or > 8 hours) and obesity (Body Mass Index 30 kg/m2), which have enormous public health impact. Using data from the National Health Interview Survey, an ongoing nationally representative cross-sectional study of non-institutionalized US adults (≥18 years) (1977 through 2009), we examined hypothesis that is independently related to overweight/obesity, with adjustment for socio-demographic, risk, medical...
To determine the effect of self-reported clinical diagnosis obstructive sleep apnea (OSA) on longitudinal changes in brain amyloid PET and CSF biomarkers (Aβ42, T-tau, P-tau) cognitively normal (NL), mild cognitive impairment (MCI), Alzheimer's disease (AD) elderly.
Current evidence has shown that, overall, actigraphy is an excellent tool for unobtrusive documentation of sleep/wake activity in normal individuals. However, a number methodological issues remain to be resolved warrant its use clinical research. In this paper, we report the results study aimed at development new scoring software that can accurately identify sleep and wakefulness. Using total time as index comparison, was optimized on calibration sample prospectively tested validation...
Abstract: The effects of immediate‐release melatonin on circadian rest‐activity profiles, cognition, and mood were investigated in ten elderly individuals with self‐reported sleep‐wake disturbances. Melatonin (6 mg), administered 2 hr before habitual bedtime, enhanced the rhythm improved sleep quality as observed a reduction onset latency number transitions from to wakefulness. However, total time was not significantly increased nor wake within reduced. ability remember previously learned...
Abstract Study Objectives: To date, conflicting observations have been made regarding ethnic differences in sleep patterns. Plausibly, differing sampling strategies and disparity the cohorts investigated might help explain discrepant findings. our knowledge population-based studies investigating complaints not addressed within-group heterogeneity, although health disparities documented. Design Volunteers (n =1118) this study were community-residing older European Americans African residing...
Background: Ethiopia is one of the most notable family planning success stories in sub-Sahara Africa. In last fifteen year, there a fivefold increase use contraceptive method. Much this attributable to short term methods. This study was assess method mix, utilization and factors associated with use. Methods: A community based cross-sectional conducted among married women aged 15-49 years Gedeo zone 2015. Multistage sampling technique used select total 1056 participants. pre-tested structured...
Sleep plays a pivotal role in both physical and mental health. quality can be affected by many socio demographic factors, such as race and/or ethnicity, well economic status (SES). Chronic sleep deprivation is associated with unhealthy behaviors alcohol abuse also places individuals at risk for chronic diseases including obesity, cardiovasculardisease (CVD), depression, anxiety. This review explores the common factors SES that lead to disturbances. Among these are shift work, poor dietary...
Decades of empirical observations have established the validity actigraphy primarily in individuals without sleep disorders. Methodological problems encountered thus far coupled with widespread use signal need for concentrated efforts to establish a consensus regarding scoring procedures. Currently available methods show less reliability clinical populations. To address these issues two validation studies were conducted: one disorders and other patients diagnosed insomnia. The results using...
This study examined whether ethnic differences in insomnia symptoms are mediated by repressive coping styles. A total of 1274 women (average age = 59.36 ± 6.53 years) participated the study; 28% were White and 72% Black. Older Brooklyn, NY recruited using a stratified, cluster-sampling technique. Trained staff conducted face-to-face interviews lasting 1.5 hours acquiring sociodemographic data, health characteristics, risk factors. sleep questionnaire was administered individual styles...
<b><i>Background/Aims:</i></b> Psychological conditions are increasingly linked with cardiovascular disorders. We aimed to examine the association between psychological distress and hypertension. <b><i>Methods:</i></b> used data from National Health Interview Survey for 2004-2013. Hypertension was self-reported 6-item Kessler Distress Scale assess (a score ≥13 indicated distress). a logistic regression model test assumption that hypertension...
The prevalence of obesity has been continually increasing, as have its associated comorbidities and health care costs. Effective management early intervention measures are necessary to overcome this global issue. responsibility for preventing managing epidemic does not lie solely on an individual, but also the entire system. Policy makers-nationally globally-must play their roles solve In review article, we examine methods controlling through interventions, such a low caloric diet, physical...
The absence of circadian zeitgebers in the social environment causes misalignment, which is often associated with sleep disturbances. Circadian defined as a mismatch between sleep-wake cycle and timing system, can occur either because inadequate exposure to light-dark cycle, most important synchronizer or reduction light transmission resulting from ophthalmic diseases (e.g., senile miosis, cataract, diabetic retinopathy, macular degeneration, retinitis pigmentosa, glaucoma). We propose that...
Obstructive Sleep Apnea (OSA) is a common co-morbid condition in stroke patients. It represents very important risk factor for addition to the other established ones such as hypertension, cardiovascular disease (CVD), hyperlipidemia, atrial fibrillation (AF), type 2 diabetes mellitus (T2DM), stress, smoking, and heavy drinking. Although United States prevalence of OSA has somewhat decreased from previous years, globally its remains constant, or some cases, on rise. In this review we present...
Survey and laboratory evidence suggests several factors affecting sleep-wake patterns of college students. These include social academic demands, diminution parental guidance, reduction total sleep time, delayed bedtime, increased nap episodes. In this study, we examined the problem falling asleep in school as a correlate negative moods population ( N = 294). A multivariate analysis showed significant main effects sleepiness on mood states based Profile Mood States. Students who fell...
Few minority patients with sleep apnea have been evaluated or treated. This study ascertained adherence rate to referrals for evaluation by primary care physicians in a community-based sample of black patients; it also examined baseline characteristics likely influence rates.
We ascertained the prevalence of resistant hypertension (RH) among blacks and determined whether RH patients are at greater risk for obstructive sleep apnea (OSA) than hypertensives. Method . Data emanated from Metabolic Syndrome Outcome Study (MetSO), a study investigating metabolic syndrome in primary-care setting. Sample 200 (mean age = 63 ± 13 years; female 61%) with diagnosis provided subjective clinical data. was defined using JNC 7and European Society guidelines. assessed OSA Apnea...
