Cardiorespiratory fitness and physical activity in children with cancer

Purpose This study assessed cardiorespiratory fitness (CRF), physical activity (PA), and sedentary behavior (SB), as well as factors associated with these outcomes in children during or shortly after cancer treatment. Methods Cross-sectionally, CRF data, obtained by the cardiopulmonary exercise test...

Description
Summary:Purpose This study assessed cardiorespiratory fitness (CRF), physical activity (PA), and sedentary behavior (SB), as well as factors associated with these outcomes in children during or shortly after cancer treatment. Methods Cross-sectionally, CRF data, obtained by the cardiopulmonary exercise test, and PA and SB data, obtained by an accelerometer, were assessed in children with cancer (8–18 years old). Linear regression models were used to determine associations between CRF, PA, or SB and patient characteristics. Results Among 60 children with cancer, mean age 12.6 years, 35 boys, 28 % were during cancer treatment. CRF, reported as the z score of VO 2peak , showed that 32 children had a VO 2peak z score which was −2 below the predicted value. CRF was significantly associated with PA and SB: each additional activity count per minute resulted in 0.05 ml/kg/min VO 2peak increase and each additional minute sedentary reduced VO 2peak by 0.06 ml/kg/min. Multiple linear regression models of PA and SB showed that decreased activity was significantly associated with higher age, being fatigued, being during childhood cancer treatment ( p
