P18-016 - Acceptability of a Wearable Dietary Monitoring Device in Patients of a Pediatric Obesity Clinic

Sunday, Jun 10
8:00 AM – 6:00 PM

Objectives: To assess the acceptability of a wearable dietary monitoring device in patients of a comprehensive pediatric obesity clinic.
The study participants were 13 to 17 year old boys (n=7) and girls (n=6) who were patients of a pediatric obesity clinic in Los Angeles, CA. Two gender-specific focus groups were conducted and audio recorded for data collection purposes. The participants were provided a brief explanation of the functionality of the prototype and were shown different prototype designs. Participants tried on the prototypes and viewed a demonstration on how the prototype and phone application worked. The participants were then asked a series of questions regarding comfort, design, functionality, others’ perceptions, interest in using the device, and if they thought it would contribute to a change in their eating and drinking habits. The two-audio recorded sessions were transcribed. The content was coded by systematically analyzing the transcripts to draw out themes within the two groups using Grounded Theory. 
Analysis of the focus group transcripts indicated that both boys and girls found the concept of the wearable dietary monitoring device and phone application potentially beneficial and conceptually innovative. However, the participants found the prototype necklaces to be uncomfortable and lacking visual appeal. Designs that mirrored commercially sold necklaces were found to be more attractive. Suggestions to enhance the functionality of the phone application included reminders, incentives, positive reinforcement, and multipurpose features. Both groups desired customization capabilities to individualize the color and style of the prototype necklace and phone application. 
The development of wearable dietary self-monitoring devices may allow for increased adherence to dietary recommendations to support patients participating in weight management programs.  However, further improvements to the comfort, design, and functionality of these prototypes should be made to increase acceptability. Additional studies should be conducted after modifications are made to distinguish an operational prototype for larger scale trials.
