TY - JOUR TI - Fit survivor DO - https://doi.org/doi:10.7282/T3VM4GGN PY - 2018 AB - Adolescent and Young Adult (AYA) childhood cancer survivors (CCS) exhibit an increased risk for chronic disease states. Poor lifestyle behaviors characterized by lack of physical activity and unhealthful nutrition practices may further exacerbate this risk. This necessitates a need to develop interventions to prevent the manifestation of this delayed disease risk. PURPOSE: To evaluate the efficacy of a multicomponent 12-weel intervention, Fit Survivor, which combined 8-weeks of supervised resistance exercise (RE) and health education, a smartphone application, wearable activity monitor, and social media on strength, body composition, quality of life (QoL), and body-esteem. METHODS: A randomized controlled trial was conducted for 12-weeks with assessments performed pre and post intervention. Participants were randomized into experimental (EXP, N=9) or control (CON, N=10). Assessments included body fat percentage (BF%), bench press (BP), leg press (LP), quality of life (QoL), and body-esteem measures. EXP were provided the smartphone application, Fit Survivor with social media integrated into it, and a Fitbit Charge. EXP participated in 8-weeks of supervised resistance-band exercise and health education sessions. The EXP group was encouraged to continue using Fit Survivor for rest of the 12-week intervention. An analysis of variance was conducted with an alpha level of 0.05. Effect sizes were represented by Cohen’s d. RESULTS: A non-significant (p>0.05) increase was observed in CON for BF% and FM, but not in EXP. EXP demonstrated a non-significant (p>0.05) increase in FFM. EXP increased BP (CON: d=0.06, EXP: d=0.30) and LP (CON: d=0.13, EXP: d=0. 52) to a greater degree than CON. Most QoL and body-esteem measures were non-significantly reduced over the intervention. CONCLUSION: The intervention improved strength and potentially prevented an increase in BF%. However, QoL and body-esteem were shown to non-significantly decrease possibly due to an unintended burden caused by the intervention or a high psychosocial baseline functioning which caused a regression to the mean. Overall, Fit Survivor was shown to have beneficial effects with regards to body composition and strength with more research needed to elucidate its effects on psychosocial markers.
