Background: This study characterizes the walking limitations of bariatric surgery candidates by age and body mass index (BMI) and determines factors independently associated with walking capacity. The setting was multi-institutional at research university hospitals in the United States. Methods: Participants of the Longitudinal Assessment of Bariatric Surgery study (n=2458; age 1878 yr, BMI 3394 kg/m 2) attended a preoperative research visit. Their walking capacity was measured by self-report and the 400 m Long Distance Corridor Walk (LDCW). Results: Almost two thirds (64%) of subjects reported limitations with walking several blocks, 48% had an objectively defined mobility deficit, and 16% reported at least some walking aid use. In multivariate analysis, BMI, older age, lower income, and greater bodily pain were independently associated (P
