Sedentary behavior and its pattern are associated with postural balance and fear of falling in asymptomatic adults: a cross-sectional study

Abstract Objective: Sedentary behavior (SB) is an independent predictor of all-cause mortality when compared to moderate-to-vigorous physical activity (MVPA). However, the influence of SB on the fear of falling (FOF) has not been investigated. We aimed to evaluate the association of SB and FOF in middle-aged and older adults. We conducted a cross-sectional study. FOF was achieved through the International Fall Efficiency Scale. SB and MVPA were obtained using triaxial accelerometers. Multiple linear regressions were performed to verify the association between SB, MVPA and FOF. Results: 75 middle-aged and older adults participated to the study. Sedentary breaks presented a more important role than the sedentary bouts and the MVPA in FOF. The SB and its pattern present a determinant association with postural balance and FOF in middle-aged and older adults. Hence, our findings reinforce the importance of middle-aged and older adults to perform the recommended amount of MVPA to maintain postural balance and reduce FOF.
