Physical Activity Counseling for Children With Cystic Fibrosis

Physical activity is recommended as a component of the cystic fibrosis (CF) treatment regimen. However, to date, there is limited research examining the effects of behavioral counseling interventions aimed at increasing physical activity. The aim of this study was to assess the feasibility of a theoretically informed, parent-mediated counseling intervention in increasing habitual physical activity and quality of life among children and youth with CF.

Participants were recruited from the pediatric respirology clinic at the Children's Hospital of Winnipeg. Participants ranged in age between 8 and 18 y. A randomized control feasibility trial was implemented, and participants were randomized to the intervention (n = 7) or control group (n = 6). Intervention group participants engaged in 4 counseling sessions to examine the acceptability and feasibility of physical activity counseling in the care of children with CF. The primary outcome was study feasibility, as measured by recruitment, retention, adherence, acceptability, and the frequency of adverse events. Secondary outcomes included physical activity and quality of life, as measured by accelerometry and the Pediatric Quality of Life Inventory.

Thirteen subjects completed the study. No adverse events were found in this trial. The intervention was found to be feasible and acceptable with good recruitment, retention, adherence, and acceptability. Positive trends were also reported in terms of increases in physical activity, reductions in time spent being sedentary, and improvements in most dimensions of quality of life pre- to post-intervention.

The findings suggest that counseling is feasible for the CF community. An appropriately powered randomized controlled trial is required in the future to investigate the utility of counseling as a means to enhance quality of life and physical activity behavior.
