Title: Healthy Child Weight Through Improved Parent Practices and Environmental Change
Brief Summary: This purpose of this project is to determine whether this 8-month parenting for healthy weight intervention is able to help parents improve their parenting skills and make positive changes in the nutrition and physical activity environment at home.


Options:
A: Inclusion Criteria:

* Grade 4 students. We chose to intervene with youth in grade 4 for four primary reasons: (1) the large majority of youth in grade 4 are in tanner stage 1 and will not experience puberty-related weight gain during the school year; (2) previous experience by our group revealed that attendance throughout the school year is higher in students in grade 4 relative to students in grade 5 or 6; (3) students in grade 4 are old enough to perform low organized games included in the intervention; and (4) retention rates in the intervention are greater than students in grades 5 and 6.

Exclusion Criteria:

* While all students will be invited to participate in the intervention, for measurement purposes, we will exclude data from those students who may not respond to the intervention or would be unable to participate in the physical activity aspects of the component. This includes children with: (1) musculoskeletal injuries that limit physical activities; (2) treatment for chronic conditions that would elicit weight gain or limit participation in physical activity (insulin, corticosteroids, blood pressure medications); (3) poor attendance (\<60% of school days) in the first semester; (4) children whose parents are unwilling to provide consent. Note: the intervention will be offered to youth with chronic conditions, however their data will not be included in the final analysis, due to confounding effects of medications.
B: Inclusion Criteria:

* Families must have at least one child age 2-5 years. The scientific rationale for focusing on this young population is that this age range includes the period often referred to as the "adiposity rebound," which has been identified as one of the critical periods for obesity development. Additionally, children of this age are still subject to strong parent and family influences which may be amenable to intervention.
* At least one parent or caregiver in the household must be overweight (BMI ≥25); however, this does not have to be the participating parent. The scientific rationale for focusing on families with at least one overweight parent is that having an overweight parent increases the child's risk of becoming overweight.
* Parents must be willing to participate in measures and intervention activities, and give consent for child's and his/her own participation.

Exclusion Criteria:

* Parents who are unable to speak English or comprehend standard age-level materials will be excluded. Currently funds are not available to translate and provide the program in Spanish or other languages.
C: Inclusion Criteria:

Children participants 3rd or 4th grade student in participating school (during first school year of study)

Exclusion Criteria:

Not a 3rd or 4th grade student
D: Inclusion Criteria:

* Schools with at least one full course of 3rd of early childhood education and one of 1st primary school.
* The Boards of Governors (community participatory organ in each school) give its approval to the intervention and measurements at the beginning and end of the course.
* Children 4 to 7 years old.
* Children's parents/caregivers will give their written consent to the children's participation.
* Collaboration in the family to respond to questionnaires on family leisure habits, sleeping, eating, getting around town, etc., included in the measurement protocol of this project.

Exclusion Criteria:

* Have a malformation that prevents learning of the Spanish language (or Spanish sign language).
* Have some kind of physical or mental disorder identified by parents or teachers that prevent physical activity.
* Have a chronic illness such as heart disease, diabetes or asthma, as determined by your pediatrician/family doctor -after analysis of the activities program- prevents participation in them.
