Web-based Delivery of Effective Treatment for Growth in Cystic Fibrosis

Optimizing nutritional status and growth improves health outcomes and survival in children
with cystic fibrosis (CF). Better pulmonary function, as measured by forced expiratory rate
in 1 second (FEV1), is associated with body mass index (BMI) above the 50th percentile for
age and gender for children with CF1. Evidence based practice guidelines recommend that
nutritional treatment for children with CF ages 2 to 20 years should aim to achieve and
maintain a BMI > 50th percentile, however across 117 CF centers in the United States 57% of
girls and 56% of boys failed to meet this recommendation1. The investigators have developed
a highly effective behavioral plus nutrition intervention (BE IN CHARGE) and demonstrated
its efficacy when delivered face-to-face to produce weight gain and its superiority over
nutrition education alone. Although endorsed by the CF Foundation as an evidence-based
treatment, it is not available to most CF Centers or families due to lack of trained
personnel, cost, and distance issues. With funding from the CF Foundation the investigators
developed a web-based delivery system of their efficacious behavioral plus nutrition
intervention for parents of children with CF ages 4 to 9 years of age. Using a Place
Outcomes Award the investigators have conducted beta testing of the web-intervention and
made appropriate modifications. The current study represents the next steps in refining
and testing our web-based intervention. This study will demonstrate feasibility and collect
pilot data on the effectiveness of the intervention in a pilot randomized trial of 20
treatment naïve participants.
