Calcium DXA: Impact of Calcium Supplements on Lumbar Spine Bone Mineral Density
An observational study of Healthy, run by University of Wisconsin, Madison at 1 site in United States.
Trial summary
We, the investigators at the University of Wisconsin, hypothesized that ingesting calcium tablets prior to a spine bone density scan will not affect the bone mineral density as measured by dual energy x-ray absorptiometry (DXA). Read more about this study

About this study
Official title: Impact of Calcium Supplements on Lumbar Spine Bone Mineral Density
We, the investigators at the University of Wisconsin, hypothesized that ingesting calcium tablets prior to a spine bone density scan will not affect the bone mineral density as measured by dual energy x-ray absorptiometry (DXA).
Read the detailed description
We hypothesized that ingesting calcium tablets prior to a spine bone density scan will not affect the bone mineral density as measured by DXA. To test this, 36 subjects ingested various calcium supplements after a spine DXA scan and were then scanned again 15, 30 and 45 minutes after ingestion. Subsequently a subset of 15 subjects had three spine scans performed for instrument precision and subsequently ingested a calcium tablet with scans 15 and 30 minute intervals after ingestion.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 28 Mar 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
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.
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?
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 28 Mar 2016.
