Filter by:The purpose of this study is to teach primary care physicians effective ways to counsel overweight and obese adolescent patients to attain a healthy weight. Fifty physicians and up to 660 adolescent patients from Duke University Health System (DUHS) Primary Care Clinics will take part in this study. Patients will be identified by research study staff and asked if they would be willing to have their clinic visit audio recorded for research purposes. There are three phases of data collection. First, baseline encounters (n=200, 4 per physician) are audio recorded. Then, half of the physicians will be randomized to receive a tailored web-based intervention containing information about evidence-based techniques to help adolescents attain a healthy weight. A new set of 200 encounters (4 per physician) will be audio recorded. Then, all physicians will receive a Summary Report that outlines the adolescent's high risk behaviors that contribute to weight (sweetened beverages, fast food, breakfast, physical activity, screen time, and sleep) and a new set of 200 encounters will be audio recorded. Data will be collected by trained data technicians, in-person and over the phone. Data is collected on laptop computers and then downloaded into password protected electronic files on a secure network server. All participants (adolescent patients and physicians) will be assigned a code number that is the sole identifier on all study data forms. Prior to and after coding, digital files will be stored in password protected directories to which only the data technicians and project manager have access. The web-based intervention will be password protected.
The purpose of the proposed study is to determine whether the amount children sleep is associated with changes in hormones, hunger, motivation to eat, and food intake. Fifty children 8-11 years old who sleep 9-10 hours per night will be enrolled for a 3-week study. For 1 week each, children will be asked to sleep their typical amount, increase their sleep by 1-½ hours, and decrease their sleep by 1-½ hours. Half of the children will be asked to increase their sleep first and half to decrease their sleep first. During each week, the following will be gathered: sleep duration (measured by actigraphy, which is a small device that measures sleep), levels of hormones measured through blood draws, self-reported hunger and appetite, food intake (measured by 3 days of 24-hour recall), how motivated children are to eat (measured using a computer activity), and child height and weight. We believe that when children sleep less they will show changes in hormones associated with hunger and appetite, report being hungrier, be more motivated to eat, and eat more food.
The hypothesis for this study is that some individuals may be at much higher risk to develop type 2 diabetes and that the individual diabetes risk will be predicted by the individual level of slow wave sleep activity (SWA).
This study aims to determine whether abnormal bodily rhythms contribute to elevate the risk of diabetes, independently of the amount of sleep loss.
This study will examine the relationship between the amount of slow wave sleep (deep sleep) and the ability of the body to bring the blood sugar level to a normal range after receiving glucose.
Obesity is one of the biggest threats to health in the 21st century. Rapid weight gain in the first year of life tends to lead to overweight in children, which in turn leads to overweight in adults. This rapid early weight gain occurs most often at weaning when eating patterns emerge. Infant sleep problems also appear to be associated with the risk of becoming overweight, and contribute to maternal post-natal depression. We propose to undertake a 4-arm randomised controlled trial to determine whether extra education and support for families around weaning and development of early food and activity habits, with or without intervention to improve infant sleep, will decrease the current risk patterns of rapid excessive early childhood weight gain in New Zealand. This would provide strong evidence for the value of such a strategy in the long term control of the obesity epidemic and its consequent complications. This is a two-year intervention with follow-ups at 3.5, 5 and 11 years of age.
The purpose of the study is to determine whether individualized social activities, physical resistance training and walking, and a combination of both are effective in improving nighttime sleep in elders with dementia.
The purpose of this study is to determine whether participating in a Mindfulness-Based Stress Reduction (MBSR) program increases mindful attention and awareness, and whether anticipated changes in mindfulness relate to improved emotional well-being, sleep quality, physical symptoms of stress, sense of spirituality, and quality of life following MBSR.
The purpose of this project is to look at how sleep affects glucose values in children with Type 1 Diabetes Mellitus. It will also evaluate if glucose is affected by times of day due to the body's own internal rhythm also known as the circadian rhythm.
This study involves research to test how Vyvanse (study drug) affects sleep in 24 children aged 6 to 12 years who have ADHD. Vyvanse is approved by the FDA for the treatment ADHD of in children aged 6 to 12 years. The experimental part of this study is to determine how Vyvanse affects sleep.
