P09-05 Can physical activity make up for the self-care disability effects of too much sitting?

OBJECTIVES: To determine whether or not, and, what extent the association between sedentary time, moderate to vogorous physical activity and self-care disability. METHODS: Sedentary time was measured with accelerometers. Self-care disability was assessed with th barthel index. A multivariate regression model was used to ascertain the effects of the interaction between sedentary time and moderate to vigorous physical activity on the disability of participants. The Jhonson-Nyeman model was used to estimate the exact mvpa thresfold from which the effect of sedentary time on disability ceased to be significant. Design: Cross-sectional Participants: 122 (84 females, mean age 85 years old) older adults. RESULTS: We found a significant effect of sedentary time on self care disability (p > 0.5). The results also indicated that mvpa moderates the relationship between self-care disability satatus and sedentary time. 51 min/day of mvpa would neglect the sedentary time effects on self care disability. CONCLUSIONS: The negative effects of sedentary time on self care disability can be offset with 51 min/day of mvpa.
