Preoperative physical activity levels and XXXX post-esophagectomy.

@entity1 @entity73 @entity260
@entity260 ( @entity260 ) after esophagectomy have been reported to occur in 15-30% of @entity1 and are the most common causes of major morbidity and mortality. Risk factors for the development of @entity260 include @entity73 , cardiac reserve, aerobic capacity, and body composition. Physical activity is associated with these factors but has not been examined in relation to the risk of developing a PPC. The aim of this cross-sectional study was to investigate if there was a difference in physical activity levels, lung function, and body composition in @entity1 who developed a PPC post-esphagectomy compared with those who did not. Consecutive @entity1 were studied preoperatively: (i) lung function with a portable micro-medical spirometer; (ii) body composition analysis using a Tanita BC 418 machine (Tanita Corp., Tokyo, Japan); and (iii) physical activity with an accelerometer (RT3, (StayHealthy, Monrovia, CA, USA)). Thirty-seven @entity1 were studied, mean age 61    9 years. @entity260 developed in 10 @entity1 (27%). Smoking status, lung function, and body composition were similar in both groups. For physical activity, there were significant differences in the time spent sedentary (20.0    1.5 h/day [PPC], 18.4    2.1 h/day [non-PPC]; P < 0.05) and in moderate activity (20    13.7 min/day [PPC], 36    20.7 min/day [non PPC]; P < 0.01). @entity1 who developed a PPC engaged in less physical activity than those who did not; hence, targeting physical activity preoperatively may result in less @entity260 .
