Background: Endometrial cancer (EC) is the most common cancer of the female reproductive organs affecting over 66,000 US women annually. EC is more common in White women, but mortality is higher in Black women. EC survivors experience a 3-6-fold greater risk for cardiovascular disease (CVD) compared to the general population. Poor 24-hour activity behaviors including sedentary behavior, physical inactivity, and sleep, contribute to CVD risk. The primary aim of the study was to investigate 24-hour activity behaviors in Black and White EC. A secondary aim was to explore differences between 2020 and subsequent years due to restrictions associated with the COVID-19 pandemic. Methods: From 2020-2022, we recruited an online convenience sample of 14 EC with 9 self-identifying as White (43 ±22 years, 55% college degree, 78% household income <$50,000, 89% full-time employment) and 5 as Black (28 ± 8 years, 100% college degree, 80% household income <$50,000, 60% full-time employment). Participants self-reported 24-hour activity behaviors including weekday SB (WD-SB), weekend SB (WE-SB), moderate-to-vigorous physical activity (MVPA), and sleep. An independent samples t-test was used to compare 24-hour movement behaviors between Black and White EC and between 2020 and subsequent years. Significance was set at p=0.05 and mean differences are reported. Results: White EC survivors reported significantly more WD-SB (13 hours, p=0.002) and WE-SB (14 hours, p=0.005). White EC survivors reported more MVPA (44 minutes, p=0.012). There were no racial differences in sleep (p=0.534). More WD-SB (10 hours, p=0.015) was reported in 2020 compared to 2021/2022, however there were no differences between years between WE-SB, MVPA, and sleep (all p> 0.05). Conclusions: EC survivors reportedly spend the majority of their day in SB and are not meeting the recommended ACSM MVPA guidelines. Lifestyle interventions aimed at promoting healthy 24-hour activity behaviors should start by targeting one activity behavior at a time and may need to be individualized to start with SB reduction or PA promotion.
