AB Aim: To compare patterns of sedentary behaviour and physical activity (PA) in people following lung resection for primary non-small cell lung cancer (NSCLC) with healthy controls.Methods: Participants between 6 to 10 weeks following lobectomy for primary NSCLC (LC-group) and age and gender-matched healthy controls (HC-group) wore two activity monitors (SenseWear Armband [SWA] and Stepwatch Activity Monitor [SAM]), during waking hours, for 7 consecutive days. Using SWA data, Metabolic Equivalent of Tasks (METs) was taken to measure the proportion of time during waking hours participants spent in sedentary behaviour (<1.5 METs), light (1.5 to 3.0 METs), moderate (3.0 to 6.0 METs) or vigorous intensity PA (>6.0 METs). Daily step count was measured via the SAM.Results: Data were available on 18 participants with NSCLC (13 females; age 68 ± 9 yr [mean ± standard deviation]; BMI 25 ± 5 kg·m-2) and 17 healthy controls (10 females; age 69 ± 5 yr; BMI 26 ± 4 kg·m-2). Daily step count was lower in the LC-group (9,056 ± 3,777) compared with the HC-group (11,455 ± 2,882) (p = 0.04). Compared to the HC-group, the LC-group spent a greater proportion of time in sedentary behavior (69 ± 14% versus 61 ± 13%; p = 0.04) and a smaller proportion of time in light PA (20 ± 9% versus 26 ± 8%; p = 0.03). Time spent in moderate and vigorous PA was similar between the groups (p > 0.05).Conclusions: People following lobectomy for NSCLC walk less than their contemporaries. They appear to increase the time spent in sedentary behaviour at the expense of time spent in light intensity PA. These data suggest that interventions aiming to decrease sedentary behaviour in this population are indicated.
