Background: Frailty is a complex concept involving a state of greater vulnerability to adverse health factors related to increased chances for morbidity and mortality. Insufficient physical activity is related to increased vulnerability to adverse health outcomes in older adults. Prolonged sitting is a health risk for cardiovascular diseases and all-cause mortality. Moderate-to-vigorous physical activity (MVPA) and sedentary behavior (SB) are known to affect health. However, studies on the effects of MVPA and SB on frailty in Korea are insufficient. This study aimed to identify the effects of MVPA and SB on frailty in healthy Korean farmers.
Methods: Frailty status was classified according to the cardiovascular health study of Fried et al. with 5 domains: unintentional weight loss, exhaustion, low physical activity, slow gait speed, and weakness of handgrip strength. MVPA and SB were evaluated using the International Physical Activity Questionnaire. To examine the association of physical activity and SB with frailty, chi-square and Multivariate logistic regression analysis was used. Statistical significance was defined as p ≤ 0.05.
Result: We evaluated 504 agricultural workers (age range=40 to 73 years old, female 49.4%). Participants were classified as robust (n=256, 50.8%) and frail group (prefrail and frail; n=248, 49.2%). Related factors with frailty were older age (65≤; OR=2.311, P>0.001), lower MVPA (<150min/week; OR=4.181, P<0.001), and higher SB (180<; OR=1.524, P=0.046).
Conclusion: Frailty is more prevalent among older adults who have lower MVPA than 150min/weak and more than three hours in a day SB in this study. The identification of the relationship between frailty and physical activity aids in the planning of adequate programs for the Korean elderly. This result demonstrated that the exercise programs for the prevention of frailty should focus on increasing physical activity as well as reducing sitting time. We hope that these results could be valuably used for prevention for frail.
