About this study

Official title: The Influence of Dietary Restraint, Social Desirability and Food Type on Accuracy of Reported Dietary Intake

The purpose of this study is to evaluate the influence of dietary restraint, social desirability, and food type on the accuracy of dietary intake reported during a 24-hour recall.

Read the detailed description

The purpose of this study is to investigate the influence of the interaction among dietary restraint, social desirability, and food type ("healthy" vs. "unhealthy") on the accuracy of reporting consumption of a laboratory meal during a 24-hour dietary recall. The automated multiple-pass method (AMPM) of 24-hour dietary recall is considered the gold standard of dietary assessment however the potential for error and biases is widely acknowledged with a tendency towards underreporting. Underreporting has been linked to many factors including two individual characteristics, dietary restraint and social desirability. Both dietary restraint and social desirability have been extensively studied however the influence of their interaction on reported dietary intake is not fully understood. In addition, a relationship to the types of foods (healthy vs. unhealthy) has also been found. For this study, 40 normal-weight female participants will be recruited at The University of Tennessee using flyers inviting volunteers. Participants will be categorized by dietary restraint, high or low, and social desirability, high or low, based on questions during the initial screening. In a laboratory setting participants will consume a meal of pre-weighed foods, including both "healthy" and "unhealthy" foods. The following day, an AMPM 24-hr dietary recall will be conducted with the participant over the telephone. Accuracy of the reported dietary intake of the laboratory meal will be determined by the equation [(reported intake - measured intake)]/measured intake] x100 for amount (weight or volume) and energy (kilocalories) with comparisons between groups and within food types using mixed factorial analysis of variance.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lunch meal with 24 hour dietary recallOther

    Each participant will come into the laboratory for a buffet-style lunch meal, where they are instructed to sample each of the foods served. On the next day, a 24 hour dietary recall is performed to test the participants ability to accurately report amounts and types of food consumed. Measures of dietary restraint and social desirability are taken prior to the laboratory meal via phone interview.

Questions about this trial

What is this clinical trial studying?

A study testing Lunch meal with 24 hour dietary recall in people with Dietary Assessment and 24-hour Dietary Recall, run by The University of Tennessee, Knoxville at 1 site in United States.

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 5 Apr 2018. 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.

What does the primary outcome measure?

Accuracy of reported dietary intake compared to measure intake of a laboratory meal. (time frame: 1 day.). 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 5 Apr 2018.
