Rural communities in the southern U.S. suffer a disproportionate burden of morbidity and mortality from cardiometabolic disease, with traditional risk factors explaining only a modest proportion of the excess burden of disease. There is considerable evidence that multiple dimensions of sleep health, including sleep duration, efficiency, timing, and regularity, as well as the disorders sleep apnea and insomnia, affect cardiometabolic disease risk. However, there is currently a lack of systematically developed sleep data in rural populations. The RURAL Sleep Study is an ancillary study to a recently initiated longitudinal epidemiology study in rural Appalachia and Mississippi Delta (the RURAL Study). The RURAL Sleep Study will add measures of sleep health to the complex individual, social and environmental factors and health outcome measures being evaluated by the RURAL Study, by incorporating minimally burdensome measures of multiple dimensions of sleep health. The results are expected to inform health care providers, public health officials, and the general public of the prevalence, risk factors, and consequences of impaired sleep health in these rural communities, providing a critical basis for prevention, recognition, and management of sleep disorders and improvement of sleep and cardiometabolic health.
Sleep is a physiological state that is essential for human performance, including academic, occupational, interpersonal, and psychological aspects. Sleep disruption or deprivation leads to a loss of psychomotor skills and an increased association with various diseases. Therefore, it is critical to assess how chronic sleep deprivation affects medical residents who work long shifts, including those assigned during their training.
Investigators developed a brief, scalable, behavioral Sleep Promotion Program (SPP) for adolescents with short sleep duration and sleep-wake irregularity, which relies on two individual sessions and smart phone technology to deliver evidence-based strategies. This R34 will test the feasibility and initial effectiveness of the SPP program and provider training via pilot randomized controlled trial (RCT, n=50) comparing SPP to Sleep Psychoeducation, a brief session on healthy sleep habits. Participants will be adolescents (12-18 years) with short sleep duration, sleep-wake irregularity, and depression.
Investigators developed a brief, scalable, behavioral Sleep Promotion Program (SPP) for adolescents with short sleep duration and sleep-wake irregularity, which relies on one individual session and smart phone technology to deliver evidence-based strategies. This open trial portion of the R34 will focus on conducting an open trial (n=8) to iteratively refine provider training, implementation procedures, and SPP program, per participant and staff feedback.
The current study will determine protein nutritional status (MPS and WBPB) in response to military-relevant sleep loss, and whether an even protein nutrition distribution during recovery optimally supports MPS and WBPB. Adults (n=20) will complete a 7d sleep satiated phase (~7-9h target/d), a 4d military-relevant sleep restriction phase (~4h /d), and a 3d recovery phase (~7-9h target/d) in a randomized, parallel design. During recovery, volunteers will consume 1.6 g protein/kg/d as an even (~0.4/0.4/0.4/0.4 g/kg) or skewed (~0.11/0.27/1.15/0.07 g/kg) distribution. Sleep will be monitored throughout the study using wrist actigraphy and diaries. During each phase, integrated daily MPS will be estimated using ingested deuterium oxide, salivary and blood sampling, and muscle biopsies, while WBPB will be estimated using ingested 15-N alanine and urine collections. At the end of each phase, metabolic testing will be used to assess the effects of sleep loss on substrate utilization and include consuming a carbohydrate beverage, serial blood draws, indirect calorimetry, and steady-state aerobic exercise. The knowledge products derived from the proposed effort will be informative to next generation ration development and support military-specific recovery nutrition guidance following operations involving sleep loss.
Sleep is not simply the absence of wakefulness. Sleep is an active procedure, normally happening every night, and is absolutely vital. Good sleep is essential for our well-being. Survival without food can be further than without sleep. Work time and commuting time seem to affect total sleep time and night bedtime. Social and work obligation can, therefore, suppress sleep time. Sleep deprived individuals may be facing anxiety and depression symptoms. The aim of this study is to investigate the presence of anxiety and depression symptoms among adults with the use of the smartphone application Onar. Onar app will be used to gather information from wearable devices of the users including total sleep time, sleep efficiency, wake after sleep onset time. An established questionnaire (Hospital Anxiety Depression Scale/ HADS) will be used to quantify and detect the presence of anxiety and depression in the study population.
In a laboratory protocol in healthy adults, exposed to a prolonged period of wakefulness with a restricted opportunity for sleep (40h of wakefulness / 3h of sleep / 21h of wakefulness), we hypothesize that the relative increase in spectral power of Delta waves [ 1 - 4 Hz] in NREM in the frontal territory, identified as a potential marker of the restorative function of sleep, during a night of sleep with limited recovery (3 h of time in bed) after sleep deprivation (40 h of continuous wakefulness), will be less important in subjects with poor recovery in terms of cognitive performance than in those with good recovery.
The overall objective of this application is to develop a mobile health platform for the pediatric care setting to promote longer sleep duration for childhood obesity prevention.
The goal of this clinical study is to assess the effects of different photobiomodulation (PBM) conditions in men and women between 25 and 65 years old with daytime sleepiness/drowsiness and /or mild mood complaints but be otherwise healthy. The main question it aims to answer are: 1. Does PBM significantly affect health and well-being? 2. Are PBM effects wavelength dependent? 3. Are PBM effects pulse dependent? 4. Are the eyes needed to assert an PBM effect or is exposure only to the skin sufficient? 5. What are the cellular, metabolic pathways underlying the systemic effects of PBM. Participants will have to: 1. Exposed themselves 5 times per week during 2 weeks to the PBM stimuli between 9:30 and 12:30. 2. A week before the baseline measurement, participants will have to start wearing a Fitbit Versa 3, and will have to continuously wear until the end of the study. 3. In the afternoon of the baseline day as well as in the afternoons after 5 and 10 PBM sessions (week 1 and week 2, respectively), participants will have to go to the lab for blood withdraw. 4. In the evening of the baseline day as well as in the evenings after 5 and 10 PBM sessions (week 1 and week 2, respectively), participants will have to collect saliva samples as well as to complete questionnaires. It will be a double-blind placebo-controlled field study with a between subject comparison.
