About this study

Body composition analysis is frequently used in both clinical and research settings for evaluation of nutritional status and follow-up. Bioelectrical impedance analysis (BIA) is one method that has been extensively used to measure body composition. To ensure the reliability of BIA results, several recommendations are proposed in the literature. One of them is to avoid coffee and caffeine prior the test. This instruction is primarily based on the potential diuretic effects of caffeine however few studies evaluated the impact of coffee on fluid balance. Research participants usually have several commitments, especially those enrolled in clinical trials. Simplified and evidence-based instructions can avoid unnecessary restrictions and lead to better participant compliance.

Read the detailed description

Body composition analysis is frequently used in both clinical and research settings for evaluation of nutritional status and follow-up. Using only anthropometric measures is outdated considering the increasing transition towards an individualized treatment and the recent advances in body composition assessment.

Methods to evaluate body composition in humans are chosen mostly based on compartment of interest, study population and feasibility. Bioelectrical impedance analysis (BIA) is one method that has been extensively used to measure body composition. This method uses an impedance that can penetrates both intra- and extracellular fluids to estimate total body water, fat-free mass and body fat.

To ensure the reliability of BIA results, several recommendations are proposed in the literature. One of them is to avoid coffee and caffeine prior the test. This instruction is primarily based on the potential diuretic effects of caffeine, which mechanisms are not completely understood. However, few studies evaluated the impact of coffee or caffeine (supplement) on fluid balance.

Coffee is a highly consumed beverage worldwide. Coffee is one of the most consumed beverage among adults in Canada, and most of the caffeine consumed by adults comes from this beverage. In addition, coffee bioactive compounds such as methylxanthines can influence BIA results due its diuretic effect. Research participants usually have several commitments, especially those enrolled in clinical trials. Simplified and evidence-based instructions can avoid unnecessary restrictions and lead to better participant compliance. To the best of our knowledge the current study is the first to explore the effect of coffee with two different amounts of caffeine on BIA-derived body composition parameters.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Body fat predicted by bioelectrical impedance

    To determine whether the consumption of coffee affects the predicted values of body fat derived by Bioelectrical Impedance Analysis in healthy adults

    Measured: up to 1.5 hours

  2. Body water predicted by bioelectrical impedance

    To determine whether the consumption of coffee affects the predicted values of body water derived by Bioelectrical Impedance Analysis in healthy adults

    Measured: up to 1.5 hours

Questions about this trial

What is this clinical trial studying?

A study testing Instant Coffee in people with Healthy, run by University of Alberta at 1 site in Canada.

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 2 inclusion and 5 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 19 Sep 2024. 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 Canada. 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. Some participants in this study may receive a placebo. 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.

What does the primary outcome measure?

Body fat predicted by bioelectrical impedance (time frame: up to 1.5 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

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 19 Sep 2024.
