N2 - Introduction: Twenty-four-hour movement behaviors—moderate-to-vigorous physical activity (MVPA), light physical activity (LPA), sedentary behavior (SB), and sleep—are crucial factors affecting older adults’ health. This study used a compositional data analysis approach to examine the associations of time spent in these behaviors with cardiometabolic health, physical fitness, and mental health among older adults. It also identified estimated changes in these health outcomes by reallocating SB time to other movement behaviors.Methods: A population-based cross-sectional study of 4562 participants (average age 67.68 ± 5.03 years; 55.8% female) was conducted in Hubei, China, between July 25 and November 19, 2020. Measures included demographics, movement behaviors, cardiometabolic indicators (body mass index, waist circumference, waist–hip ratio, percentage body fat, systolic and diastolic blood pressure), physical fitness, and mental health outcomes (depressive symptoms and loneliness). Compositional data analyses were conducted in R.Results: MVPA and sleep time were associated with greater health outcomes (all P < 0.001), except blood pressure (P = 0.13–0.83). LPA time was associated with waist circumference (B = 0.313, P = 0.009), waist–hip ratio (B = 0.003, P = 0.003), physical fitness (B = 0.36, P < 0.001), and mental health indicators (both P < 0.001). Reallocating 30 minutes of SB to MVPA and sleep was associated with predicted improvements in all health outcomes, except blood pressure, whereas reallocating 30 minutes of SB to LPA resulted in predicted improvements in physical fitness (0.187 units), depressive symptoms (−0.264 units), and loneliness (−0.395 units). For dose–effect relationships, reallocating 5–60 minutes of SB to MVPA showed the greatest benefits for all health outcomes.Conclusions: This study provides timely empirical evidence for future interventions and policymaking on promoting healthy aging in the post-COVID-19 era. The findings underline the importance of including 24-hour movement behaviors in future health promotion among older adults.
