Filter by:Adiposity is a key link between lifestyle factors (like diet and exercise) and cardiovascular (CV) disease. However, little is known about the link during the juvenile years, when the processes leading to CV disease are at an early stage of development. The specific aims are as follow: (1) to determine the relations of free-living diet and exercise to total body percent fat ( percentBF), visceral adipose tissue and CV fitness in black and white boys and girls of varying socioeconomic status. (2) to determine the relations of fatness and fitness to different CV disease risk factors. Design and methods: (1) Recruit 800 14 to 18 year olds, 200 in each ethnicity and gender subgroup. (2) Assess diet with seven 24-hour recalls, and exercise with two seven-day recalls and heart rate monitoring. (3) Measure percent body fat with dual-energy x-ray absorptiometry, visceral adipose tissue with magnetic resonance imaging and CV fitness with a multi-stage treadmill test. (4) Measure major fatness- and fitness-related CV disease risk factors (e.g., total cholesterol:HDL cholesterol ratio, insulin, systolic blood pressure, left ventricular mass indexed to height, fibrinogen). (5) Conduct multivariate and univariate analyses to determine relationships.
The purpose of this study is to evaluate the effectiveness of a neuromuscular training program in decreasing sport and recreational injuries and improving healthy outcomes in junior high school students (grades 7 to 9). The neuromuscular training program is implemented as a 15-minute warm-up at the beginning of the students' physical education classes over a three-month period. This study is a randomized controlled trial design, involving twelve schools over a three-year period. Upon enrolment into the study, schools are randomly assigned to the intervention (neuromuscular training) group, or the control group. The control group includes a standard-of practice warm-up consisting of aerobic components and static stretching. A study athletic therapist visits the schools each week to assess and record information on any injuries sustained by study participants. Baseline health and physical fitness is measured at baseline, and again at 3-month follow-up in study participants to assess changes over the course of the program.
The primary objective of this study is to determine the efficacy of a novel enteral nutrition (EN) protocol (delivering 75% of patient's caloric needs through EN) for induction of remission in patients with active childhood-onset Crohn's disease (CD) and compare it to the standard protocol with exclusive enteral nutrition (EEN). This novel approach allows patients to consume remaining calories (25%) from an antiinflammatory diet for CD (AID-CD). The hypothesis is that no significant difference in the remission rate between the novel EN protocol with partial enteral nutrition (PEN) and standard protocol with EEN will be observed.
This research study examines the feasibility of using an in-vehicle mobile technology monitoring system to measure teen secondary task engagement during on-road driving as the outcome measure for a web-based intervention to prevent risky driving in novice teen drivers.
The specific aim of this study is to assess the feasibility of a web-based intervention to prevent risky driving with teen drivers licensed in the previous 90 days.
Accumulating evidence suggests a role of G protein-coupled inwardly-rectifying potassium (GIRK) channel in the pathology of excitement of nerve, and the medicine with the action (like the Tipepidine Hibenzate) is expected as a new curative medicine of adolescent depression. The purpose of this research is to confirm the effect by carrying out the additional dosage of the Tipepidine Hibenzate to the adolescent patients with depression. If suggestion is obtained by this research about the effect on adolescent patients with depression of Tipepidine Hibenzate, it can contribute to development of the medical treatment of adolescent patients with depression.
Research has shown that questionnaires completed on the internet have the potential to provide more complete and honest data with fewer errors in a more efficient manner than questionnaires completed using the paper and pencil format. Despite the numerous advantages of internet-administered questionnaires, it is important to make sure that the internet questionnaires will yield comparable results to the well-established paper and pencil versions. No one has studied internet administration of scoliosis specific questionnaires in adolescents with scoliosis. The investigators will test whether the internet administration of scoliosis questionnaires is as reliable as the traditional paper and pencil version. The investigators predict that the internet-administered questionnaire will provide the same reliability as the paper-administered questionnaires.
Our goal is to investigate how hormones that control blood sugar, hunger, and stomach emptying change with puberty and being overweight. These substances change with a meal. - For this, we need to compare lean and overweight children. - We need to study them before and during puberty. - All children in the study will be tested before and after a liquid meal.
The primary purpose is to estimate the prevalence of depression and subsyndromal states among adolescents 13 to 17 years consulting to hospital emergency rooms for any reason, for they are another way of tracking this suffering, as they host many troubled teens at once for health problems and accidents sometimes iterative, reflecting their risk behaviour. Secondary purposes are to assess the feasibility and desirability of a post-emergency medical consultation for adolescents who scored high on a self-administered questionnaire, and to assess the impact of this approach by later monitoring.
The global epidemic of obesity in childhood continues to evolve and threaten future health and life expectancy primarily due to the increased incidence of cardiovascular disease. Obesity is strongly related to high blood pressure (hypertension) and both conditions pose a risk for target organ damage, which can follow a subject from childhood into adult life. The AORTA study will investigate central hemodynamics and organ damage in 100 obese children and adolescents in order to gain insight to the complex interplay of hypertension, obesity and subclinical damage in order to intensify more precise prevention, thereby reducing the future development of cardiovascular disease.
