Brief summary
The National Heart, Lung, and Blood Institute (NHLBI) of the National Institute of Health (NIH) has sponsored a consortium of four sites across the United States, entitled Childhood Obesity Prevention and Treatment Research (COPTR). Each site has its own protocol. Case Western Reserve/Cleveland's project is entitled Targeting Obesity and Blood Pressure in Urban Youth. The site name is IMPACT (Ideas Moving Parents and Adolescents to Change Together). The project assesses the effects of three interventions on Body Mass Index(BMI) in overweight and obese urban 5th-8th grade youth: a cognitive-behavioral intervention (HealthyChange), a systems improvement intervention (SystemsChange), and an education-only intervention (Tools4Change). In addition the study assesses the potential additional impact of a school-community based intervention on outcomes. The project has two phases: a formative phase (including focus groups and a pilot) and the main trial. The main trial will take place over approximately four years.
Detailed description
The IMPACT trial will involve a 3-arm randomized controlled trial of three behavioral and educational interventions: (1) HealthyCHANGE, a behavioral approach focusing on building skills and increasing intrinsic motivation (based on cognitive-behavioral theory with motivational interviewing components); (2) SystemCHANGE, an innovative behavioral approach focusing on system re-design of the family environment and daily routines (based on social-ecological and personal process improvement theories); and (3) education-only (representing usual care, called Tools4CHANGE). In the main trial, approximately half of the children will also be in schools that take part in the We Run This City (WRTC)Marathon program, a school-based fitness program administered by the YMCA, and half will be in schools that do not take part in the WRTC program. This study will assess the impact of the interventions on the main trial's (1) primary outcome, Change in Body Mass Index (BMI). (2) secondary outcomes including diet, physical activity, sedentary behavior, sleep, blood pressure, cardiovascular risk, body composition, fitness, and quality of life (3) mediators including : child's self-efficacy, social support, motivation, family problem solving ability, systems thinking, and self-regulation;(4) moderators including: socioeconomic status, demographic factors, environmental factors, personal and psychosocial characteristics of child and parent.
Interventions
Cognitive behavioral strategies to address diet, physical activity, sedentary behavior and sleep for children. It involves an intensive series of group sessions, followed by rotating monthly face-to-face meetings or phone calls.
Intervention (based on systems improvement and choice architecture theories) System improvement and choice architecture theories seek to teach a set of skills using family self-designed experiments to redesign daily routines regarding eating, activity and sleep.

Dietary Intake- Percent Calories From Fat
The annualized change of percent of calories from fat over 3 years. Percent calories from fat slope (trajectory over 3 years) was created for each participant with outcomes multiply imputed for children without diet recall data post-baseline. An F test with two numerator degrees of freedom was used to test for between-group differences using an alpha of .05.
Time frame: Baseline, 12 months, 24 months, 36 months

Dietary Intake- Sodium
The annualized change in sodium intake (mg) per day over 3 years. Sodium intake slope (trajectory over 3 years) was created for each participant with outcomes multiply imputed for children without diet recall data post-baseline.

Fitness
The annualized change in pacer laps completed during PACER test over 3 years. PACER test slopes (trajectory over 3 years) were created for each participant with outcomes multiply imputed for children without PACER test measurements post-baseline. An F test with two numerator degrees of freedom was used to test for between-group differences using an alpha of .05.

Physical Activity
Annualized change in physical activity measures of moderate to vigorous minutes per day and bed rest/sedentary minutes per day as measured by accelerometer. Physical activity slopes (trajectory over 3 years) were created for each participant with outcomes multiply imputed for children without accelerometer readings post-baseline. An F test with two numerator degrees of freedom was used to test for between-group differences using an alpha of .05.

Quality of Life- Perceived Stress
The annualized change in perceived stress over 3 years. Participants are asked to rate individual scale items on their perception of how often they feel specific stressors on a scale from 0 (never) to 4 (very often). Individual scale items are summed for a total score. Higher scores indicate higher perceived frequency of stressors, therefore higher perceived stress. Outcomes are reported as the mean of the slope estimates for total perceived stress score over 3 years (from baseline to 36 months). The perceived stress slope (trajectory over 3 years) was created for each participant with outcomes multiply imputed for children without stress scores post-baseline. An F test with two numerator degrees of freedom was used to test for between-group differences using an alpha of .05.
Time frame: [Baseline, 12 mos, 24 mos and 36 mos]

Sleep
The results reflect the annualized change in adolescent sleep wake scale and pediatric daytime sleepiness scale. The items of the adolescent sleep wake scale are recoded to have a minimum of 0 and maximum value of 5, in which a higher scores for both the individual items and the overall sum score indicate a better outcome. The items of the pediatric daytime sleepiness are recoded to have a minimum of 0 and maximum value of 4, in which a lower score for both the individual items and the overall sum score indicates a better outcome. Sleep slopes (trajectory over 3 years) were created for each participant with outcomes multiply imputed for children without post-baseline measures. An F test with two numerator degrees of freedom was used to test for between-group differences using an alpha of .05.
