(S)Partners for Heart Health: Promoting Nutrition & Physical Activity in 5th Grade
Spartners for Heart Health is a school-based intervention designed to increase percentage of students achieving national recommendations for nutrition and physical activity behaviors in addition to maintaining or improving cardiovascular disease risk factor status. The purposes of this investigation are to further hone and demonstrate sustainability and dissemination of the intervention.

Identifying Physical Activity and Activity Context via Wearable Wireless Networks
The major goals of the project are to create a wearable wireless network for physical activity assessment, to determine if the network can detect various physical activities, and to establish biological relevance of the output from the network (i.e., develop an energy expenditure prediction equation).

R21 HL090705 (Lorraine Robbins, PI) 04/01/2009–03/31/2011
Middle School Physical Activity Intervention for Girls
The major goals of this project are to test the feasibility of and obtain preliminary evidence of efficacy for a 6-month “Girls on the Move” intervention (guided by the Health Promotion Model and Social Cognitive Theory) that uses monthly motivational, individually tailored counseling sessions plus after-school physical activity (PA) to increase MVPA and fitness, as well as improve body composition and cognition and affective responses related to MVPA among 6th-grade girls.

Project FIT
The major goals of the project are to work with community organizations to increase access to safe and affordable physical activities, to improve affordability and availability of nutritious food, and to increase knowledge, attitudes, and beliefs associated with healthy living. Participants are low-SES students in grades 3-5 in elementary schools in Grand Rapids, MI.

Short and Long Term Effectiveness of Exergames for Young Adults
There are two main purposes of this investigation. The first purpose is to design a physically active video game for college students, both male and female, and test how much energy is expended while playing the game. The second purpose is to devise an intervention to increase physical activity in sedentary college students using the finished product of the game.

Multi-Component Intervention to Increase Physical Activity in Preschool Children
The purpose of this project is to examine the effects of a multi-component intervention that is designed to increase physical activity energy expenditure in 3- to 5-year-old children. Preschool-based components include high-quality physical education, active recess periods, physical activity integrated into learning, and changes to the physical and social environment to promote physical activity.

Longitudinal Validity of Accelerometry in Youth
One major goal of the project is to assess the longitudinal validity of accelerometer energy expenditure prediction equations and physical activity count cutpoints in children and adolescents. The other major goal is to examine the sensitivity to change of accelerometry as a measure of physical activity.

Community and School Partnership to Increase Activity and Improve Nutrition
The goals of this project will be to: 1) Conduct formative assessment with community stakeholders interested in addressing health disparities in minority children and families in Flint, Michigan; 2) Develop and implement a community-based intervention to increase physical activity and improve dietary behaviors in minority children and families in four neighborhoods of Flint, Michigan; and 3) Assess the effects of the intervention on health-related variables (physical activity, dietary behaviors, BMI z-score, etc.) in minority children and primary caregivers.

Girls on the Move Intervention
The purpose of this school-based cluster randomized controlled trial (RCT) will be to test the efficacy of our intervention multi-component intervention including motivational interviewing by school nurses and an after-school physical activity club to increase MVPA among middle school girls. Secondary outcomes will include CV fitness (number of laps run), body mass index (BMI), and % body fat (% BF).We will also examine if MVPA is mediated by cognitive and affective variables.
