Description
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. Results: Participants achieved an average of 21.1 (SD=18.9) minutes of daily MVPA, and 62.1 (SD=8.7) percent of their daily time was spent sedentary. Mean nightly sleep time was 408.9 (SD=55.7) minutes, with an average sleep efficiency of 85.6 (7.5). These rest-activity variables clustered to form five behavior profiles including: 1) fairly active poor sleepers, 2) inactive average sleepers, 3) fairly active average sleepers, 4) active average sleepers, and 5) very active average sleepers & low sitters. Sleep was comparable across four of five behavior profiles (n=345, 92.5%). The behavior profile with the poorest sleep had the lowest proportion of whites (35% vs 78-91%, p < .001) and college graduates (28% vs 68-90%, p = .004). The largest profile (n=151, 40.6%) engaged in 7 min of MVPA per day. BMI and physical functioning varied across behavior profiles. Other health variables did not vary statistically, but trended in hypothesized directions. Conclusions: Daily rest-activity behaviors do cluster in women to form distinct behavior profiles. These identified behavior profiles can inform population targeting or intervention goals of multiple health behavior interventions.
