Cost-effectiveness of Family Based Pediatric Obesity Treatment

State University of New York at Buffalo50 enrolled

Overview

To determine the cost effectiveness of treating the child alone and parent alone to traditional family-based method of obesity treatment. It is hypothesized that a family-based approach will be more cost effective, and will support the savings and effectiveness of treating multiple family members together.

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.

Outcomes

Primary Outcomes

Change in Standardized BMI

The formula is BMI = kg/m2 where kg is a person's weight in kilograms and m2 is their height in metres squared. Children's BMI also accounts for age and sex.

Time frame: baseline, 6 months, 12 months

Secondary Outcomes

change in quality adjusted life years (QALY)

The quality-adjusted life-year (QALY) is a measure of the value of health outcomes. Health is calculated by length of life and quality of life. QALY takes the value of years living and the quality into a single index number. The QALY calculation is the change in utility value resulting from the treatment multiplied by the duration of the treatment effect to provide the number of QALYs. QALYs can then be incorporated with medical costs to arrive at a final common denominator of cost/QALY.

Time frame: baseline, 6 months, 12 months
