Physical Activity Compliance to American Cancer Society Recommendations Amongst Hematopoietic Stem Cell Transplant Survivors.

ABSTRACT

BACKGROUND AND OBJECTIVES: The aims of this study were to determine the extent to which hematopoietic cell transplantation (HCT) survivors adhere to the American Cancer Society recommendations for weekly physical activity and identify potential demographic and transplant characteristics associated with the lack of compliance. METHODS: This cross-sectional study included adults who had undergone HCT and were at least 1 year post transplantation. Physical activity was assessed using the screening tool of the Block 2014. The type of activity, frequency, and intensity were converted into the metabolic equivalent of task (MET) scores (0-499.0 MET min/week, inadequate activity; 500-1000 MET min/week, adequate activity; >1000 MET min/week, highly vigorous activity). RESULTS: Participants (n = 81) reported a median MET score of 153 min/week, and 83% failed to reach the physical activity guideline of >500 MET min/week. Only 17.3% met the ACS recommendations, with three reporting above 1000 MET min/week. Median daily moderate and vigorous physical activity minute totals were 18.0 and 5.9 min/d, with 85.2% and 60.5% of participants involved, respectively. The median total physical activity energy expenditure was 744 kcal/d. Only race was associated with MET score, with Whites reporting higher MET scores. CONCLUSION: Most HCT survivors assessed in this study did not meet the ACS physical activity recommendations. These findings reinforce the need to incorporate screening for physical activity into HCT survivorship care, offer counseling to those who do not meet the recommended levels, and encourage a physically active lifestyle among HCT survivors.
