研究概览
简要总结
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).
详细描述
If you are eligible and you choose to participate in this study, you will be asked to come to the Pennington Biomedical Research Center in Baton Rouge between 7:00 and 11:00am after a 10-hour fast (nothing to eat or drink besides water for 10 hours prior to your appointment). The study visit will take approximately five hours. During the visit, you will complete the informed consent process and then complete several body measurements and body composition procedures immediately afterwards.
Description of study procedures
Body Measurements (about 10 minutes):
A series of body measurements will be taken by trained staff. These measurements include height and weight. These measurements will be completed twice during this time. You will wear a hospital gown and bathing suit for these measurements. Your BMI will be calculated from these measurements.
Body Composition and Circumference Measurements Deuterium Dilution (heavy water) This test is to measure the amount of water in your body. After a fasting urine sample is collected, you will drink a glass of water that has been enriched with an atom called a stable isotope (deuterium). After you drink this non-radioactive heavy water, you will provide urine samples several times over the next 4 hours.

结局指标
主要结局
The Primary purpose is to measure children and adult body composition data using different methods - bioimpedance analysis (Tanita®), DXA (GE Medical), BodPod (Life Medical).
时间窗: One five hour visit (Baseline)
Tanita® has several Bioelectrical Impedance Analysis (BIA) systems on the market. BIA is considered one of the most reliable and accessible methods of screening body fat. This study will collect data from the Tanita® systems, DXA, BodPod, and total body water to further improve the accuracy of Tanita® products for adults and children.
次要结局
- The secondary outcome measure it to improve the BIA body composition using deuterium dilution (heavy water), body circumferences (tape measure, TC2, Human Solutions), and tissue thickness by ultrasound (GE Medical, BodyMetrix).(One five hour visit (Baseline))
