A systematic review of
7 prospective studies on
television time and 1 study
on computer use
Six studies of varying quality
demonstrated a positive relationship
between screen time and the
development of obesity

Seventy children studied
every 6 mo during 2 y in
a randomized controlled
study to decrease television
viewing 50% and decrease
sedentary activity in the
intervention group of 35
e intervention decreased
sedentary activity especially in lower
socioeconomic group children; there
was relationship between decreased
television viewing, decreased BMI,
and decreased energ y, but not
increased activity

Increased family involvement in prevention
Fieen RCTs of family-based
lifestyle interventions for
children and adolescents
Family-based interventions based in
behavior theory had more effect than
did those theoretically connected to
family systems theory
–
A systematic review
including 24 studies
including parental
involvement in long-term
weight control interventions
with a nutritional focus
Although there were inadequate
data to determine whether parental
involvement in prevention programs
is important, medium and high
levels of parental involvement in
obesity treatment programs improved
outcomes, suggesting that parental
involvement should be studied in
prevention
Probable +
Fieen studies (7 were
longitudinal) included
measures of frequency of
family meals although in an
inconsistent manner
ere was inconsistent and weak
evidence of an inverse association
between the frequency of family meals
and risk of pediatric overweight; there
is need for robust longitudinal studies
on this topic
None
A systematic review of 9
studies including portion
manipulation interventions
or portion education/
training interventions
Most studies demonstrated increased
intake with increased portion size,
and that parents can be educated to
estimate portion size more accurately,
but there were other studies that
contradicted both concepts
