* p < 0.05; LTPA: leisure-time physical activity; PA: physical activity; LPA: Light physical activity; MVPA: Moderate-to-vigorous physical activity; M: mean; SD: standard deviation; df: degree of freedom. Independent sample t-tests were performed to compare the differences of time spent in physical activity and sedentary behavior between older adults with and without a healthy diet.
