ATTITUDES REGARDING EATING and ACTIVITY (AREA)
Childhood obesity is a national public health epidemic. Presently, obesity is estimated to affect nearly twenty-one percent of adolescents between the ages of twelve to nineteen years. One important but understudied risk factor for weight gain and obesity development is attitudes about healthy eating and physical activity participation. This study seeks to better understand how attitudes about eating and physical activity are formed in older adolescents. We are recruiting University of Michigan students 18-21 years old. This project is funded by the University of Michigan Childhood Disparities Research Laboratory. For more information on how to participate in this study, click here!
EXERCISES FOR A HEALTHY ASTHMA LIFESTYLE AND ENJOYMENT (ExHALE)
Children with asthma experience many barriers to physical activity, one of which is exercise itself can trigger an asthma attack. Asthma symptoms usually occur within 5 to 15 minutes after the initiation of exercise, making participation in sustained aerobic exercise difficult. This study examines the feasibility of short bouts of physical activity in children with and without asthma. Additionally, this study is examine differences in exercise tolerance, exercise enjoyment, and motor competency in children with and without asthma aged 8-16 years. This project is funded by the University of Michigan MCubed Program and School of Kinesiology. For more information on how to participate in this study click here!
INTERRUPTING PROLONGED SITTING with ACTIVITY (InPACT)
In collaboration with the Taubman College of Architecture and School of Education we are using a multidisciplinary approach to combat the current epidemics of childhood obesity and physical inactivity. INPACT is a novel classroom-based physical activity intervention to improve the fitness of both teachers and students, while simultaneously improving academic achievement. Our goal is to provide teachers with the necessary resources and instruction to lead their classes in 5, 4-minute activity breaks throughout the school day. These short duration activity breaks closely represent children's natural physical activity patterns and may be an effective tool at energizing and motivating students to be physically active. The aim is to provide students and teachers with a cumulative of 20 minutes of enjoyable exercise at a moderate-vigorous intensity each school day. INPACT has been implemented in four elementary schools: Anderson Elementary (Trenton), Eastabrook Elementary (Ypsilanti), Columbia Elementary (Brooklyn), and Munger Elementary-Middle School (Detroit). For more information, visit the study website at: www.inpact.kines.umich.edu. The project was funded by the University of Michigan School of Public Health Momentum Center, University of Michigan MCubed program and the Michigan School of Kinesiology.

THE EFFECT OF BUILT AND SOCIAL ENVIRONMENTS ON CHILDHOOD OBESITY AND RACIAL/ETHNIC DISPARITIES IN THE NATIONAL HEALTH COMMUNITIES STUDY
In collaboration with the Environment & Policy Laboratory in which we are expanding the Healthy Communities Study (HCS). We are examining the effects of the built and social environment on childhood obesity. We plan to obtain data on a broad range of current and historical built and social environment characteristics of the HCS communities (i.e., food availability, park availability, food prices, physical activity facilities, land use, street connectivity, and crime) and then spatially link these data to the 5,000 families living in 130 geographically and racially diverse communities. This study combined with the parent study, will be one of the most comprehensive childhood obesity studies in terms of its size, scale, quality of measures, and potential for scientific contributions to prevent childhood obesity. This project is funded by the National Institutes of Health.
USING TECHNOLOGY TO INCREASE THE REACH OF THE InPACT PROGRAM
With funding from the University of Michigan Center for Educational Outreach we are currently developing teacher training videos to expand the reach of the program. These videos will include instructional content and testimonials from teachers who successfully implemented InPACT in their classrooms. It is our hope that by including strategies and methods used by previous InPACT teachers, these videos will become a valuable resource for teachers across the state and country seeking to enhance movement and learning in their classrooms. Resources already available on our website (www.inpact.kines.umich.edu) include: teacher training manuals, classroom floor plans, activity videos, and parent education.
In collaboration with the University of Michigan Taubman College of Architecture & Urban Planning and School of Public Health’s Momentum Center, Active Class Space examined the classroom environments of 3rd - 5th grades with a goal of redesigning the typical classroom to make the environment conducive to increased movement and decreased sedentary behavior among students. This project was funded by the University of Michigan MCubed Program and the School of Public Health Momentum Center.

HEALTH & CULTURE PROJECT
This study sought to better understand the role of cultural identity and identity-based motivation. These two cultural factors may help to explain gender disparities in pediatric obesity among African-American adolescent boys and girls. This project utilized Identity-Based Motivation Theory to clarify the complex relationships between culture, physical activity, diet and obesity risk. This study was funded by the University of Michigan Office of the Vice President for Research.

STRESS REACTIVITY IN ADOLESCENCE
This project investigated the role of stress on the health of Latino, African-American, and non-Latino white adolescents. In the United States alone, pediatric obesity has more than tripled in the last 30 years, particularly among certain racial/ethnic groups including Latinos and African-Americans. This innovative research study will help to clarify the interdependent relationships between stress and health behavior that contribute to disparities in pediatric obesity. The University of Michigan's Nutrition Obesity Research Center funded this project.

STRESS, OBESITY & DIABETES IN ADOLESCENCE
Type 2 diabetes has emerged as a significant health issue in obese youth, especially among certain racial/ethnic groups including African-Americans and Latinos. This disparity is partially attributable to greater insulin resistance observed in these two groups (relative to non-Latino whites). This study investigates the role of the social environment, particularly psychosocial stressors in shaping racial/ethnic differences in type 2 diabetes. This project was funded by the American Diabetes Association.
