Title: SWITCH: Rationale, Design, and Implementation of a Community, School, and Family-based Intervention to Modify Behaviors Related to Childhood Obesity
Brief Summary: The purpose of this research is to increase community awareness about the relationship between physical activity, screen time, and nutrition and how these factors influence healthy weight management.

The problem of obesity is at epidemic proportions and has become the most important public health problem confronting the United States today. Of greatest concern is the 300% increase in obesity rates among children and youth over the past twenty years. Childhood obesity is a precursor of adult obesity.


Options:
A: Inclusion Criteria:

* All children in 3-5 grades who provide parental consent and child assent will be eligible to participate in the project.

Exclusion Criteria:

* Participants who meet the following exclusion criteria will not be considered for participation.
* Do not provide consent
* unable or unwilling to adhere to project procedures
B: Inclusion Criteria:

* Teens and parents of any gender, ethnicity/race, or socioeconomic status.
* Teens 14 to 16 years of age who are freshmen and sophomores taking a health class at one of the participating high schools.
* Teens who assent to participation.
* Teens with a custodial parent who consents for themselves and their teen's participation in the study.
* Teens who can speak and read in English (educational instruction in Arizona High Schools is conducted in English)

Exclusion Criteria:

* Teens who are under age 14 will be excluded because:

  * They are not likely to be enrolled in high school, and
  * They are unlikely to have sufficient cognitive development to benefit from the proposed intervention
* Teens who are over age 16 will be excluded for two key reasons:

  * We believe that the cognitive development of and social expectations for older teens requires a more complex and flexible intervention than that proposed, and
  * Teens need to be available for 12 month follow-up sessions (our pilot studies indicated that this becomes less likely once teens are old enough to leave/graduate from high school, emancipate from parents, and/or leave home).
C: Inclusion Criteria:

* Schools where at least 60 % of the pupils in three or more classes signs up to participate in the Study

Exclusion Criteria:
