COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
The aim of the research is to determine the level of sodium excretion and the food sources in the diet of people with coeliac disease. Participants will be provided with digital kitchen scales and asked to provide a three-day weighed food record. They will also be asked to provide a 24-hour urine sample in order to measure sodium excretion. A DEXA scan of forearm, hip and lumbar spine will be taken on one occasion to measure bone density.

Summary
Brief summary
High sodium intake, as measured by urinary sodium excretion, is associated with increased bone loss (Divine, 1995). In Australia, the national target for salt intake was achieved by only 6% of men and 36% of women (Beard, 1997). A positive relationship exists between urinary sodium and urinary calcium excretion, with repeated studies showing that a high level of salt in the diet increases calcium excretion (Ilich, 2000). Other studies have recognised that people following a gluten-free diet have a lower bone mineral density, likely related to calcium malabsorption (Scott, 2000). It is not clear from the research how much sodium is ingested by those following a gluten free diet.
