Abstract
OBJECTIVES: We measured the volume and patterns of sedentary behavior (including breaks from sedentary behavior) in a sample of older adults via accelerometry. METHODS: Inactive, older adults (≥50 years of age) were eligible to participate. A cut point of <100 counts/minute was used to estimate: (1) total volume; (2) > 10-, > 30-, and > 60-minute bouts; and (3) patterns of sedentary behavior according to time of day and day of the week were computed. Total breaks in sedentary time also were calculated. RESULTS: Participants (N = 67) were sedentary 62% of the day, engaging in 73.3 total bouts of daily sedentary behavior, and each bout lasted, on average, 7.8 minutes. All participants engaged in >1 daily bout of sedentary behavior > 10 and > 30 minutes. Sedentary time was slightly greater during the evening and on weekdays. Participants averaged 72.9 daily breaks from sedentary behavior, with each break lasting approximately 4.4 minutes. CONCLUSIONS: Our findings add valuable insights into the patterns of sedentary behaviors among older adults. Concentrated research efforts should be made to gain a clearer understanding of patterns and enablers to sedentary behaviors, which will allow for development of targeted interventions for this high-risk population.
