Encouraging Calcium Absorption and Bone Formation During Early Puberty Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for qualified medical advice, visits or professional assistance by using a real mD. We are not docs. Always confer with your physician about Encouraging Calcium Absorption and Bone Formation During Early Puberty conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Encouraging Calcium Absorption and Bone Formation During Early Puberty Clinical research trials and Encouraging Calcium Absorption and Bone Formation During Early Puberty health trials occur in many of cities throughout the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally evaluate the effectivity of new does drugs. The intent of the studies / undertakings is to resolve particular human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to detect remedies for all sorts of conditions, including Encouraging Calcium Absorption and Bone Formation During Early Puberty. Encouraging Calcium Absorption and Bone Formation During Early Puberty Clinical Trials and other clinical trials permit volunteers to obtain healthcare treatment alternatives before they are available to the masses. Most times the participants undergo professional assistance for without cost, and occasionally they are compensated for their time. Occasionally there is a cost for a Encouraging Calcium Absorption and Bone Formation During Early Puberty clinical trial. Test subjects typically receive the most expert healthcare available for their Encouraging Calcium Absorption and Bone Formation During Early Puberty condition. Dangers are a reality, however, and may include more or frequent mD visits, healthcare dangers (perhaps life-endangering), and/or the treatment being ineffectual. Trials are federally regulated with rigid guidelines to protect clinical trials patients.

Encouraging Calcium Absorption and Bone Formation During Early Puberty
For Condition: Osteoporosis,Osteopenia
Status: No longer recruiting
Sponsor(s): National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) ,
Synopsis: Increasing bone mass during puberty can ultimately decrease the risk of developing osteoporosis, which causes bones to weaken and break more easily later in life. The purpose of this study is to compare calcium absorption and bone growth in boys and girls on diets including either a nondigestible oligosaccharide (NDO) or simple sugar.
Details: Rapid increases in bone mass occur during calcium absorption and bone calcium deposition during puberty, and these increases can enhance peak bone mass and ultimately decrease the lifetime risk of osteoporosis. However, dietary, hormonal, and genetic factors likely affect increased bone mass. This study will examine if adding NDO to a pubertal diet allows more absorption of calcium by the body, producing stronger bones. The study will also assess how the hormones produced by the body during puberty affect bone growth and whether genetic factors affect calcium absorption or bone growth. This study will last 2 years. At study entry, baseline pubertal hormone levels and bone mass will be assessed. Both a dual-energy X-ray absorptiometry (DEXA) scan and a calcium stable kinetic study measuring calcium absorption will be performed. Participants will then be randomly assigned to receive calcium fortified food with or without added NDO for 1 year. Calcium absorption will be measured again at 2 months. After the first year, calcium kinetic, hormonal, and DEXA studies will be performed and compared to baseline results. A final DEXA scan will be performed at the end of 2 years.
