Background: Children surviving acute lymphoblastic leukemia (ALL) are at increased risk for overweight and obesity over that of the general population. Whether a generic or tailored approach to weight management is needed for cancer survivors has yet to be tested.
Procedure: Thirty-eight youth 8-18 years with BMI ≥ 85% who had survived ALL were recruited for a randomized clinical trial evaluating a weight management intervention (WMI) tailored for childhood ALL survivors (Fit4Life). Fit4Life recipients received a 4-month web, phone, and text message-delivered WMI tailored for cancer survivorship. Controls received a general WMI delivered via phone and mail. Assessments were performed at baseline and 4 months. Outcome data were analyzed according to assigned treatment condition over time.
Results: Most (80%, (70%, 100%) [median (IQR)]) of the assigned curriculum was received by Fit4Life participants as compared to 50% (40%, 65%) among controls. Fit4Life recipients ≥ 14 years demonstrated less weight gain (P = 0.05) and increased moderate-to-vigorous physical activity (P < 0.01) while all Fit4Life recipients reported reduced negative mood (P < 0.05) over time as compared to control counterparts.
Conclusions: We demonstrated acceptable feasibility of a WMI tailored for overweight and obese children surviving ALL utilizing a multimodal technology approach. Improved weight, weight-related behavior, and psychological outcomes were demonstrated among Fit4Life intervention as compared to youth receiving a generic WMI. Data from this pilot trial may be used to design a larger trial to determine whether youth of all ages also can derive a benefit from a cancer survivor-tailored WMI and whether short-term outcomes translate into improved long-term outcomes for childhood ALL survivors.
