The association between patterns of physical activity and sedentary time with frailty in relation to cardiovascular disease

Abstract

Abstract Objective The associations of moderate‐vigorous physical activity (MVPA) bouts and patterns of sedentary time (ST) with frailty according to cardiovascular disease (CVD) status are unknown. Methods Accelerometry in adults ≥50 years old from the 2003‐2004 and 2005‐2006 National Health and Nutrition Examination Survey were used. Bouted and sporadic MVPA in ≥10‐minute or 0.05 for CVD interaction). Frequency of ST breaks was not associated with frailty. Average ST break intensity was protective in both groups. The duration of breaks in ST was associated with lower frailty in CVD participants only (P > 0.05 for CVD interaction). Conclusion Insufficient MVPA and prolonged ST are detrimental despite CVD status.
