Importance of Breakfast and Physical Activity in Children
• Key behaviors associated with excess weight gain among youth and adolescents
• Infrequent breakfast consumption
• Infrequent physical activity

Current Childhood Obesity Rates
• United States
• 16% overweight
• 17% obese
• Philadelphia, PA
• 15% overweight
• 25% obese
• 57% of children, 6 to 11 years of age, categorized as overweight or obese
• Multi-component, community-based approaches show promise to be effective
• School-based
• Institute of Medicine recommends that schools be the focal point for childhood obesity prevention
• No other institution has as much contact with children
• Play a pivotal role in promoting healthy behaviors to prevent obesity

Purpose
• To assess the changes in the number of days of breakfast consumption and days spent participating in 60 minutes of physical activity per week, over the 2014 to 2015 school year, in children in the fifth grade provided a school-based health intervention
Methods
• 13 schools recruited to participate in a three-year school-based intervention
• From five counties in Greater Philadelphia Area
• Chester, Delaware, Montgomery, Bucks, Philadelphia
• Mixture of public, charter and parochial schools
Fit Essentials One 45-minute fitness period per month, with one take-away fitness
assignment to complete outside of school
Biannual cardiovascular health, muscular strength, balance and
flexibility measurements
Philadelphia Union 1 coach/player visits per year (90 minutes each)
Villanova Unviersity No programming
Partner Programs for Control Schools
Vetri Foundation For
Children
No programming
Greener Partners No programming
Fit Essentials No programming
Philadelphia Union No programming
Villanova University No programming
Measurements
• Population analyzed
• Children in 5th grade
• During 2014 to 2015 school year
• Health behaviors
• Youth Behavior Survey Questionnaire
• 26-question multiple choice survey
• Beginning and end of school year
Example Questions fromYouth Behavior Survey Questionnaire
• During the past 7 days, on how many days did you eat breakfast?
• During the past 7 days, on how many days were you physically active for a total of at least 60 minutes per day? (Add up all the time you spent in any kind of physical activity that increased your heart rate and made you breathe hard some of the time)

Conclusions
• No significant changes were observed in children in the 5th
grade, from the beginning to the end of the school year in
• Daily breakfast consumption
• Number of days engaged in 60 minutes of physical activity
• Although this school-based intervention may not have resulted in significant changes in healthy behaviors over one school year, the larger three-year intervention may result in positive changes
