ABSTRACT
Existing research recognizes low levels of physical activity in pediatric patients with cancer, but much uncertainty exists about their capability to self-reflect levels. The objective this study was compare results subjective self-reports and accelerometers regarding daily walking as well moderate-to-vigorous activities.Results the assessment tool StepWatchTM Activity Monitor self-reporting a standardized questionnaire were compared 28 children adolescents during cancer treatment.The 13.8±2.8 years age 3.4±2.0 months after diagnosis. Bland-Altman plots indicated fairly symmetrical under- over-estimation for minutes limits agreement ranging from -100.8 87.3 min (d = -6.7 min). Mean difference almost zero are -126.8 126.9 min. comparison days at least 60 showed marked 3.0±2.6 self-reported versus only 0.1±0.4 measured days.These findings suggest that should preferably be assessed methods. Greater efforts needed implement supervised exercise interventions treatment incorporating methods improve self-reflection activity.
