1. BACKGROUNDS: Currently, elderly people comprise more than 10% of the total Taiwanese population. However, within the context of self-reported sleep duration and health risks, research into the association between sleep duration and body composition changes in older people is limited. It is important to gain an understanding of such an association of older people to estimate the public health burden. 2. OBJECTIVES: To assess the association between self-reported sleep duration and sarcopenia as well as obesity in community-dwelling older adults. 3. HYPOTHESIS: Self-reported sleep duration is associated with prevalence of sarcopenia and obesity in community-dwelling older adults. 4. DESIGN: A cross-sectional investigation. 5. SETTING: Communities in Zhongzheng district, Taipei. 6. PARTICIPANTS: Four hundred and forty-eight community-dwelling adults (224 men and 264 women) aged 65 years and older. 7. MEASUREMENTS: The investigators evaluated self-reported sleep duration by deriving from the Pittsburgh Sleep Quality Index and 7-d recall physical activity diary. Skeletal muscle mass was estimated by the predicted equation from a bioelectrical impedance analysis measurement. The Groningen Activity Restriction Scale and the Chinese Geriatric Depression Screening Scale were used to evaluate physical disability and depression, respectively.
The study is to collect the body composition data using five different methods-bioimpedance analysis (Tanita®), DXA (GE Medical), BodPod (Life Medical), deuterium dilution (heavy water), body circumferences (tape measure, TC2), and tissue thickness by ultrasound (GE Medical, BodyMetrix).
The purpose of this study is to collect body composition data using bioimpedance analysis (Samsung) and DXA (GE Medical). Both of the methods are explained in more detail in section 5 of this consent. The data collected will help Samsung improve the products the company offers.
Inactivity among schoolchildren is a challenge to public health and for the municipality in particular. This study´s aim is to evaluate the cognitive and physical as well as social and fitness adaptations, and learning outcomes of short- and long term ball training for 9-11 years old girls and boys, and to determine to what extend the organisation (5x12 minutes og 3x40 minute a week) and type of training (ball games, circuit training or running) influence the magnitude of response.
Children born to obese women are at risk of increased adiposity and later adverse metabolic outcomes. We have conducted a follow-up study on an existing clinical trial, called the LiP study (Lifestyle in Pregnancy), registration number NCT00530439,in which 360 obese pregnant women were randomized to either lifestyle intervention or routine obstetric care. This present study follows the children until 3 years of age. We have the hypothesis, that the intervention during pregnancy results in a lower degree of adiposity and metabolic risk factors in the offspring. Clinical examination is taking place at age 2.5-3 years including anthropometric measurements, Dual energy x-ray (DXA) scans and blood samples measuring metabolic markers.
Prospective cohort, monocentric non-randomized and interventional clinical study in ICU assessing the evolution of body composition using bioelectrical impedance analysis.
Background: - Researchers want to collect information on diet, physical activity, and sun exposure in children and young adults. The data can provide information on the effect these factors might have on the development of cancer and other diseases. Information collected only from adults does not accurately measure these factors. To collect more accurate information, both mothers and children will provide information. Study participants will be from Hebei province in northeastern China and Jiangsu province in eastern China. Objectives: - To collect and study diet, activity, and sun exposure data from Chinese adolescents and their mothers. Eligibility: - Adolescents between 15 and 17 years of age from Hebei and Jiangsu provinces in China. - Mothers of the study adolescents. Design: - Participants will answer questions about their diet, physical activity, and time in the sun. - Participants will wear a pedometer to measure activity for 7 days. They will also wear a badge to measure sun exposure for 3 days. - Participants will record their activities and food and drinks consumed for 3 days. Urine samples will be collected for a full day. - Participants will have a grip strength test. On the last day of the study, they will provide blood, saliva, and toenail samples. - A smaller separate group of adolescents will provide saliva samples only and complete a food questionnaire.
This was a pilot study to validate the BC3 hydration factor which will be important for determining how well this value represents hydration status compared to assessment of total body water by D20.
The purpose of this study was to validate the Stayhealthy BC1 bioelectrical impedance analyzer to assess percent body fat in children and adults. The BC1 was compared to dual-energy x-ray absorptiometry assessment of body fat for adults and to hydrostatic weighing assessment of body fat for children. We hypothesized that the BC1 would provide similar measures of body fat between devices with acceptable limits of agreement.
