Exclusion Criteria:

Local authorities:

* Areas which have plans to decommission the HENRY intervention during the course of the trial; or who are not planning on running HENRY programmes during the trial period.

Children's Centres:

* Centres where ethnography has taken place during Study 2

* The schools must be public
* The schools must have, at the least, two classes for Preschool Education, for children 3, 4 and 5 years of age
* The schools must make available the use of the cafeteria.

C: Inclusion Criteria:

* parents having a four year old child and living in Östergötland; having the ability to have their child measured at baseline at 4.5 years ± 2 months of age
* at least one parent had to able to speak and read Swedish sufficiently well (i.e. be able to provide informed consent and understand the intervention content)

Exclusion Criteria:

* A child with a neurological or endocrine disease effecting weight
* A child with a parent suffering from a serious physical or psychological disease making the study too demanding for the family.
D: 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.

Answer: C
