Objectives: To identify latent rest-activity behavior profiles of objectively measured total sleep time, sleep efficiency, physical activity, and sedentary time in a diverse sample of U.S. women.
Methods: 372 women (mean age 55.4 + 10.2) were recruited from studies conducted across four US universities. Participants wore ActiGraph GT3X+ accelerometers on the hip and wrist for a week. Total daily minutes in moderate-to-vigorous physical activity (MVPA) and percentage of wear-time spent sedentary was estimated from the hip device. Total sleep time and sleep efficiency were estimated from the wrist device. Latent profile analyses were performed with these four rest-activity variables, and adjusted ANOVAs were conducted to compare behaviors, demographics, and health conditions across resulting behavior profiles.
