Subject Category: Physical activity and sedentary behavior
Purpose: A healthy lifestyle is associated with beneficial health effects in managing type 2 diabetes mellitus (T2DM). Important lifestyle behaviors, i.e. sleep, sedentary behavior (SB), and physical activity (PA), impact T2DM disease-specific characteristics. These behaviors are often investigated separately. A recent shift in research emphasizes the importance of considering these behaviors as part of a 24-hour day. Therefore, the aim of this study is to explore these 24-hour movement behaviors (24h-MBs) in T2DM adults.
Methods: This study currently includes data of 10 T2DM adults (mean age: 66.9y, 60% men; mean years T2DM: 9.2y) and 23 adults with normal glucose levels(NGL) (mean age: 59.35y, 40% men). Participants’ 24h-MBs were measured by actigraphy (Actigraph wGT3X+). All 24h-MBs were analyzed between adults with T2DM and NGL on an average day and on weekdays and weekend days separately. Independent Sample Ttests, Mann-Whitney U Tests, and One Sample T-tests were conducted.
Results: Means for 24h-MBs on an average day in T2DM adults were 635.26 (±76.61) min/SB; 275.7 (±63.05) minutes of light PA (min/LPA); 9.51 (±9.24) minutes of moderate to vigorous PA (min/MVPA); 6475.76 (±2366.39) step counts; 96.87% (±0.97) sleep efficiency; 478.29 (±26.21) minutes Total Sleep Time (min/TST); 12.55 (±4.29) minutes Wake After Sleep Onset (min/WASO). Means for the NGL adults were 586.55 (±68.54); 314.48 (±70.49); 18.41 (±13.70); 8048.16 (±2804.57); 95.70 (±2.11); 468.45 (±40.82); 18.24 (±9.04),
respectively. On an average day, T2DM adults spent significantly less time in min/MVPA and min/WASO compared to NGL adults (p=0.042; p=0.023). On an average weekend day, T2DM adults spent significantly more time in min/SB and less time in min/LPA compared to NGL adults (p=0.004; p=0.009). Both groups did not meet the current 24h-MB guidelines of 150 min of MVPA/week (both p<0.001 ) and a maximum of 8 hours of SB/day (both p<0.001). Meeting the sleep guideline did not significant differ.
Conclusion: These preliminary results showed high levels of min/SB and low levels of min/MVPA in both groups, which were more pronounced in the T2DM group. Recruitment is ongoing which will result in additional analyses in a larger sample. Personal, cardiometabolic and environmental correlates will be explored in the following months
