Title: Translational Investigation of Growth and Everyday Routine in Kids (TIGER Kids)

Sponsor: USDA

Principal Investigator: Amanda E. Staiano, Ph.D.

Co-Investigators: Robert Newton Jr., Ph.D., Peter Katzmarzyk, Ph.D., Stephanie Broyles, Ph.D., Catherine Champagne, Ph.D., RD, LDN

Medical Investigator: Daniel  Hsia, M.D.

Summary: TIGER Kids enrolled 342 boys and girls ages 10 to 16 years from every weight category (normal weight, overweight, and obese). Researchers at Pennington Biomedical are using state-of-the-art technology, including activity trackers and global positioning system (GPS) information, to track physical activity, imaging to measure body fat, and messages sent through a mobile phone app (called ecological momentary assessment) to identify what motivates or prevents kids from being physically active. Participants attended an orientation session at Pennington Biomedical to learn about the study, sign consent and receive their activity tracking tools. These tools were returned at clinic visit approximately 1 week later. Assessments include body measurements, blood pressure, surveys, blood draw, dietary recall and body composition. Participants will repeat the activity monitor tracking and a second clinic visit 2 years later.

 

Recruitment is closed for this study and longitudinal data collection is underway.

Title: Painted Playgrounds: A scalable approach to increasing physical activity and motor skills in Louisiana preschool aged children

Sponsor: Blue Cross Blue Shield Foundation, American Council on Exercise

Investigators: Maura Kepper, Ph.D. (Lead Investigator), Amanda Staiano, Ph.D., Stephanie Broyles, Ph.D., Elizabeth ("Kip") Webster, Ph.D.

Summary:  Preschool is a critical period during which children develop fundamental motor skills, build confidence in their movement, and start a physical activity trajectory that follows through adolescence and beyond. Unfortunately, few sustainable interventions have succeeded in increasing preschool children’s physical activity, and subsequently children are developing obesity at alarming rates. A simple, low-cost strategy is the addition of colorful markings (i.e. hopscotch, foursquare, fun trails) to existing playgrounds or open spaces. These “painted playgrounds” have been shown to be effective to increase physical activity in older school-aged children but remain understudied in preschool children. The proposed project will implement and test the effectiveness of a scalable playground stenciling intervention to increase physical activity and fundamental motor skills and decrease sedentary behaviors among preschool aged children attending childcare centers.

 

Four childcare centers are participating in this study in fall 2018.

GameSquad

Title: Gaming Technology to Encourage Healthy Weight and Activity in Youth

Sponsor: American Heart Association (Grant-in-Aid – Southeast Affiliate)

Principal Investigator: Amanda E. Staiano, Ph.D.

Co-Investigators: Robert Newton Jr., Ph.D.

Medical Investigator: Daniel  Hsia, M.D.

Summary: The goal of this randomized controlled trial is to test the efficacy of exergaming, i.e. video gaming that involves physical activity, to reduce adiposity in overweight and obese children. The study is a 6-month, 2-arm randomized controlled trial among 46 overweight/obese children (aged 10 to 12 years) assigned to: 1) 3 hours/week of in-home exergaming or 2) a control group. An innovative aspect is the inclusion of a fitness trainer who will regularly videochat with the participant and virtually monitor gameplay. The primary aim is to test the hypothesis that after 6 months, children randomized to an exergaming-based physical activity intervention will decrease BMIz compared to a control group. Body fat and ideal health factors (i.e. blood pressure, total cholesterol, fasting glucose) and behaviors (i.e. physical activity, diet, and smoking status) will be investigated as secondary outcomes between baseline and month 6 of the intervention.

Recruitment is closed for this study and results are under review.

 

 

Pause & Play

Title: Physical Activity and Screen-Time Regulations in Child Care Centers: Influence on Young Children’s Health Behaviors

Partner Organization: Mayor's Healthy City Initiative

Sponsor: NIH National Institute on Minority Health and Health Disparities (U54MD008602), Gulf States Health Policy Center

Principal Investigator: Amanda E. Staiano, Ph.D.

Co-Principal Investigator: Andy Allen (Director of the Mayor's Healthy City Initiative; Community Outreach Coordinator for the Office of the Mayor-President)

Co-Investigator: Corby Martin, Ph.D.

Summary: Louisiana’s Department of Education (DOE) is implementing new regulations for children in childcare settings in 2015 to comply with national recommendations: 1) physical activity of at least 1 hour/day and 2) screen-time limited to 2 hours/day. The DOE is also providing extensive training and programmatic support to the centers. Together with the Office of the Mayor-President of Baton Rouge, we propose the following aims: 1) to examine the physical activity and screen-time environment of licensed childcare centers before and after the enactment of new state regulations; 2) to examine the physical activity and screen-time behaviors of children enrolled in childcare centers before and after the enactment of new state regulations; and 3) to establish community strategies to improve young children’s health behaviors.

Improving Access to Pediatric Obesity Treatment  

Title: Evidence-Based Childhood Obesity Treatment: Improving Access and Systems of Care

Sponsor: Agency for Healthcare Quality and Research (R13 HS022816)

Principal Investigator: Denise Wilfley, Ph.D.

Summary: The United States Preventive Services Task Force (USPSTF) recommends clinicians screen children aged 6 years and older for obesity and offer or refer them to intensive counseling and behavioral interventions to improve their weight status. However, few children are receiving the treatment they need and obesity remains a leading public health crisis. We propose a small conference to serve as an intensive meeting of thought-leaders and stakeholders with a shared investment in increasing access to effective, evidence-based childhood obesity treatment. Deliverables will be disseminated to the broader community of childhood obesity stakeholders, including researchers, clinicians, policymakers, and the public, through publication, presentation at national meetings and via targeted webinars, and use of partner organization member networks and advocacy channels. Dr. Staiano serves on the Steering Committee and Planning Committee, along with members of The Obesity Society and the American Academy of Pediatrics.

ClinicalTrials.gov Identifier: NCT02003963

Project Summary: Klub Kinect was the pediatric pilot study for the Childhood Obesity & Diabetes Research Program at Pennington Biomedical. The purpose of Klub Kinect was to evaluate the feasibility of a 12-week exergaming dance program for adolescent girls. A dance-based exergame was selected because dance physical activity interventions have demonstrated acceptability and enjoyment by adolescent girls, most notably in the Stanford Girls’ health Enrichment Multi-site Studies (GEMS), which observed improved cardiometabolic health following a 2-year dance intervention. We aimed to determine the feasibility of recruiting, enrolling, and following overweight and obese adolescent girls in a 12-week exergaming program versus self-directed care. We also assessed changes in body weight, body fat, visceral adiposity, cardiovascular risk factors, physical activity, peer support, health-related quality of life, and self-efficacy towards exercise.
