Cost-effectiveness of Family Based Pediatric Obesity Treatment

Research has shown that family-based treatment programs produce significant short and
long-term decreases in weight relative to height. Reductions in relative weight are observed
for both parents and their children, with a significant relationship between parent and
child relative weight changes.

Usual care for families with obesity is for the parent and child to be treated separately by
their individual physicians, often with different types of treatment plans. This may be less
efficacious for the parent and child than a family-based intervention in which the parent
and child are treated together. The separate treatments may also be more expensive than
concurrent treatment following the same treatment plan.

There are many reasons to hypothesize that a family-based treatment will be more efficacious
and more cost effective than other formats for treating families with multiple generations
of obesity. If family members are treated together, they have the same treatment goals. They
can learn to support each other, model positive behaviors, work together to change behaviors
and modify the shared family environment. The simultaneous treatment of parents and children
in a group format, which is how family-based treatments are administered, reduces the time
therapists provide treatment in comparison to the usual format in which each parent and
child would be seen individually.

An important challenge for obesity treatment is to develop efficacious and cost-effective
interventions to treat pediatric obesity. The goal of this study is to evaluate the efficacy
and cost effectiveness over 12 month follow-up for 50 families with overweight parents and
children randomized to family-based behavioral treatment in comparison to the treatment of
the parents and children separately, by different therapists, which represent usual care for
families with obese parents and children.

Inclusion Criteria:

- Overweight child and parent in each family

Exclusion Criteria:

- The parent and child must have no dietary or activity limitations that would preclude
making the requested behavior changes; no current psychiatric problems and no history
of eating disorders, including anorexia nervosa, bulimia nervosa or binge eating
disorder. Families with a first degree relative with any of the mentioned eating
disorders will also be excluded. The participating child must be able to read at a
3rd grade level and demonstrate the ability to maintain diet and activity records in
a simulated recording interview. Both parent and child must be able to read the
English language well enough to understand the consent and assent forms.
