Diet Intake Estimation of Tweens and Teens: The DIETT Study

Completed

• Conditions: Diet Intake Assessment

• Registration Number: NCT02818933
• Lead Sponsor: Children's Hospital Medical Center, Cincinnati

Brief Summary

The purpose of this pilot study is to assess the quality of self-report data obtained using the Automated Self Administered 24-Hour Recall (ASA24-Kids-2014) relative to an interviewer administered 24-hour recall in a sample of adolescents ages 12-17 years, to determine their method preference, and to assess issues related to each method.

Detailed Description

Self-reported dietary intake currently provides the best approach to quantify foods and nutrients for many nutrition research studies. The interviewer administered 24-hour diet recall is generally considered the best available method; however, it is limited by a high degree of participant burden and cost. A web-based, automated, self-administered 24-hour recall (ASA24-Kids-2014) was recently designed by researchers at the National Cancer Institute (NCI) to mimic the interviewer administered 24-hour recall approach to collecting high quality dietary intake data in children and adolescents while minimizing time and cost. Although the ASA24-Kids-2014 is a potentially useful and cost-effective tool for collecting dietary data for research studies in children and adolescents, it has not been validated for use in pediatric populations. A total of 30 adolescents will be recruited to achieve the study aims. For Aim 1, 10 participants will complete one diet recall using ASA24-Kids-2014 and one interviewer administered 24-hour recall. Their feedback on both methods and preference will be assessed. For Aim 2, 20 participants will be randomly assigned to complete six (one per week) web-based or interviewer administered 24-hour recalls. Data from Aim 2 will be analyzed to determine whether the reporting quality decays over time for each method. In addition, feedback from participants in both aims will be collected on specific factors related to the recall methods such as ease of use, technical challenges, flexibility, duration, and database completeness. Results obtained from this pilot study could provide critical information to design a larger method comparison study to rigorously assess the performance of the ASA24-Kids web-based diet recall.

Recruitment & Eligibility

• Status: COMPLETED
• Sex: All
• Target Recruitment: 30

Inclusion Criteria

• Adolescents at least 12 years old and no greater than 17 years old who have access to a phone and a desktop or laptop computer.

Exclusion Criteria

• Persons having prior experience completing food recalls, either for a research study, or for personal use
• persons having prior experience with mobile food apps, either for research or for personal use
• persons following a special diet
• persons having a mental, physical, or visual limitation that would hinder their ability to use a computer or recall from memory
• Non-English speakers are excluded because using an interpreter could increase the length of time it takes to complete a dietary food recall thus, possibly skewing the data.
• those with self-reported body mass index (BMI) less than the 5th or greater than the 85th percentile (as determined during telephone screen)

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Reporting decay	6 weeks	Change (decline) in self-reported energy intake and number of foods consumed over the six-week study duration (Aim 2)
Method preference	2 weeks	Participants identify which diet recall method - interviewer-administered or web-based - they prefer overall, and on specific factors, via a qualitative feedback survey at the end of their study involvement (Aim 1)

Secondary Outcome Measures

Name	Time	Method
Feedback on recall methods	2 or 6 weeks	Participants in both study aims answer questions about different aspects of using each recall method (Aim 1) or on using their assigned method (Aim 2), such as ease of use, technical challenges, flexibility, duration, and database completeness.
