• Definitions of overweight and obesity
• Prevalence of obesity
• Causes and risks of childhood obesityy
• Young children’s eating habits
• ENHANCE frameworkENHANCE framework
• Eat Healthy, Be Active
• What’s next?• What s next?
3. Body Mass Indexy
Overweight and obesity are measured in adults by Body
Mass Index (BMI)Mass Index (BMI)
BMI = weight (in kg) divided by height (in m), squared.
(BMI=kg/m2)(BMI=kg/m2)
An adult who is 5’5” tall and weighs 144 pounds has a
BMI f 24BMI of 24.

5. Overweight and Obesity in ChildrenOverweight and Obesity in Children
For children and adolescents (aged 2–19 years),g y
the BMI value is plotted on the CDC growth
charts to determine the corresponding BMI forg
age and gender.
Overweight is defined as a BMI at or above the 85th
percentile and lower than the 95th percentile.
Obesity is defined as a BMI at or above the 95th
percentile for children of the same age and sex.
7. Childhood Obesity: Consequences
Health concerns
Heart disease
An estimated 61% of overweight
children have one risk factor
Type 2 diabetes
It is estimated that 1 in 3American
children born in 2000 will developTypep yp
2 diabetes in their lifetime (JAMA, 2003)
Asthma
O th di blOrthopedic problems
Skin Disorders

9. Causes of Childhood OverweightCauses of Childhood Overweight
Genetic tendency, based on
differences in
Appetite
Activity levelActivity level
Metabolism rate
Proximal cause: taking in more
l h h b dcalories than the body uses
Eating too many calories
Not getting enough physical activityg g g p y y
Lack of physical activity has more
impact

food ads per year and 18,000-20,000 paid

15. Points of Intervention: Earlier is BetterPoints of Intervention: Earlier is Better
Multi-level approach
Family Context
Community Context
Community supports for healthy eating and PA
Systems with which families interact
WICWIC
Extension nutrition programs
Medical care

16. RATIONALERATIONALE
• We CAN reverse the trend and counter the current obesogenic
environment
• Need a systems approach
• Approximately half of US children 0-6 spend time in non-
relative (13.9%) or center-based (36.1%) child care making
hi i i l b i ithis a critical obesity prevention context.

19. Health Belief Model
Child id ld b t lik l t d t id b dChild care providers would be most likely to adopt evidence-based
practices related to healthy child eating if they:
viewed the failure of children to meet nutrition standards as potentially damaging
to children’s health and development;
believed they could make a meaningful difference in children’s eating habits;
were given the training and tools to effect change.
Transtheoretical Model
behavior change is conceptualized as a continuum consisting of a five-
stage process.
suggests that child care providers would be in varying stages of
readiness with regards to change and require different kinds ofg g q
support to move them along the continuum.

are amenable to regulation
Small changes add up to culture change

The potential for child care providers to serve as
trusted advisors and conduits for information
dissemination has yet to be fully realized.

Children can influence adults’
behaviors.

36. Why Eat Healthy, Be Active?y y,
The early childhood classroom is an ideal place toy p
teach about healthy habits.
Preschoolers have the cognitive capacity to learn about
nutrition and physical activitynutrition and physical activity.
Young children need hands-on exploration to learn essential
concepts.
C t h ld b i l d ifiConcepts should be simple and specific.
An integrated approach is most appropriate for ages
3 – 5.3 5.
The daily curriculum structures children’s learning.
Preschoolers need multiple opportunities to practice the same
conceptconcept.
