About this study
Official title: Incorporating More Physical Activity and Calcium in Teens (IMPACT): A School-Based Osteoporosis Prevention Program for Adolescent Girls
The Incorporating More Physical Activity and Calcium in Teens (IMPACT) study was a behaviorally-based middle school nutrition and physical activity program for the prevention of osteoporosis. The goal of IMPACT was to increase calcium intake and physical activity to help build bone mass in girls.
Read the detailed description
Peak bone mass is achieved during the first twenty years of life, and dietary and activity patterns that contribute to the formation of peak bone mass are developed during childhood. The IMPACT intervention was designed to increase bone density and ultimately prevent osteoporosis during adulthood. IMPACT included physical education, food service, and classroom environmental and behavioral components and was delivered by physical education (PE) specialists, food service personnel, and classroom teachers.
A group of 718 sixth grade girls (mean age 11.1) from twelve middle schools in central Texas participated in the study. The group was 72% non-Hispanic white, 12% Hispanic, 5% African American, and 11% other ethnicity. After baseline measurements were completed in the fall of 2000, the twelve middle schools were pair-matched based on school characteristics (ethnicity, % economically disadvantaged, % girls in athletics) to a control (usual health education program) or the IMPACT program. The intervention was implemented for 18 months and consisted of three major components: a PE component, which emphasized daily weight-bearing activities (WBA); a health lessons component consisting of sixteen behaviorally-based lessons which emphasized WBA, calcium-rich foods, and osteoporosis prevention; and a food service component.
Outcome measures included physical properties of the students' heel bones, calcium consumption, physical activity, and psychosocial factors believed to be precursors to these behaviors. Changes at the school environmental level, such as the number of calcium rich foods offered in the cafeteria and the number of opportunities offered for weight-bearing and aerobic activity, were also assessed.

The record says: finished, as of the sponsor's last update on 19 Oct 2010. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00067925, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2010.
