Virtual Reality as a Dietary Education Adjunct for Pediatric Patients With Obesity

Not Applicable

Completed

Brief Summary: Childhood obesity is a national crisis, effecting up to 1 in 5 of children in the US. In the Lucile Packard Children's Hospital Pediatric Weight Management Clinic, the investigators educate parents and caregivers about the importance of dietary modification. In addition to physician guidance, the investigators partner with registered dieticians to counsel families during an hour-long interview. However, traditional methods of education are limited by long-term recall. A typical person only recalls 2- 3% of didactic content after a period of 30 days. In order to improve recall and increase involvement of our pediatric patients in their own dietary modifications, the investigators propose a pragmatic, randomized pilot study investigating the effectiveness of Virtual Reality (VR) in changing dietary choices and improving recall.

Recruitment & Eligibility

Inclusion Criteria

Exclusion Criteria

Arm && Interventions

Group	Intervention	Description
Dietary Consult with Virtual Reality (intervention)	Virtual Reality Application	Those in the VR group will receive the same educational dietary review by the registered dietician, and additionally participate in a VR experience through an application called Chaos Café. In Chaos Café, patients are immersed into a computer-generated kitchen environment. A humorous robotic chef serves children different food groups. Gameplay is advanced by choosing healthy foods, while eating unhealthy foods does not advance the application.

Primary Outcome Measures

Name	Time	Method
Immediate behavior modification	Duration of appointment, typically 2-3 hours	Immediate behavior modification will be assessed by comparing the selection of an appointment exit reward the end of the study visit. Participants will be presented with two options, either a bag of chips or a healthier alternative. Selection of reward will be recorded.

Secondary Outcome Measures

Name	Time	Method
Nutritional knowledge survey	Duration of appointment, typically 2-3 hours	15-item survey based on the counseling sessions with questions such as "If I have vegetables at home, a healthy way to eat them would be: a) fresh, b) fried, c)with cheese dip, d)in a smoothie"
Pediatric Adapted Liking Survey	Duration of appointment, typically 2-3 hours	The survey uses a continuous scale from -100 to 100 to indicate patients' like or dislike of certain foods. The survey was completed by participants after their dietary counseling. The responses were categorized into seven groups, 3 negative, 1 neutral, and 3 positive. -3=\[-100,-67\], -2=\[-66,-34\], -1=\[-33,-1\], 0=0, 1=\[1,33\], 2=\[34,66\], 3=\[67,100\]. Likability of foods were also categorized into fruits, fatty/salty/sugary (FSS), proteins and vegetables.
Satisfaction Survey	Duration of appointment, typically 2-3 hours	5-point satisfaction survey for participants who completed VR experience with questions such as "The technology helps me remember what good food choices are (select one option): (1) Not at all, (2), (3) A little bit, (4), (5) A lot"
