How concerned are you that childhood obesity is a
major problem for America's children?
15
Who has primary responsibility for ensuring
children develop good eating habits?
16
Who bears primary responsibility for addressing
the problem of childhood obesity in America?

22
Childhood Obesity Summary Areas of Agreement
  • Responsibility for ensuring good eating habits -
    parents
  • Childrens physical activity level is a top cause
    of obesity
  • Other top causes are parental role modeling,
    parental oversight, and passive entertainment
  • Television and childrens friends/peers have
    strong influence on food choices and eating
    behavior
  • Strong support for government to mandate school
    programs to address obesity problem
  • Schools should strengthen physical education
    programs

23
Childhood Obesity Summary Areas of Disagreement
  • Seriousness of the problem - dietitians and
    pediatricians more concerned than teachers and
    parents
  • Teachers and parents believe its parents
    responsibility to respond to problem Dietitians
    and pediatricians are split (parents, government
    and medical profession)
  • Dietitians think parental role modeling is much
    more important than do parents (who favor
    parental oversight)
  • After physical education there is no agreement on
    the role of schools in fighting obesity

24
Childhood Obesity Summary Conclusions
  • Bad news No agreement as to the seriousness of
    the childhood obesity problem or what role
    parents should play
  • Good news Everyone believes childhood obesity is
    parents responsibility - We need to equip
    parents to deal with the problem
  • More bad news Its not clear that government
    intervention would be welcomed by teachers and
    parents
  • More good news But, if government intervention
    did occur there is agreement that it should be
    through the schools, starting with physical
    education
