PURPOSE: The purpose of this study is to examine the relationships between sedentary behavior (SB), glycemic control, well-being, fatigue, and physical function in people with type 2 diabetes (T2D). These modifiable health variables have been shown to be 1) affected in people with T2D, and 2) associated with SB in older adults. However, the relationships between these variables and SB in people with T2D are uncertain. METHODS: A cross-sectional study design was used to assess the relationship between SB (total sitting time) with glycemic control (HbA1c), well-being (WBQ-22), fatigue (Fatigue Severity Scale), and physical function (Senior Fitness Test). An activPAL3TMactivity monitor was used to assess SB in people with T2D aged from 50 to 75 years. RESULTS: Data from 59 participants were included in the final analysis. Study participants were obese (33.4 ± 5.5 kg/m2) and sedentary (11.08 ± 2.31 Hours/day). Multiple linear regression examining the effect of the assessed variables on SB showed that poorer glycemic control (β= 0.40; 95% IC: 14.43, 58.13) was associated with higher level of SB, independent of moderate to vigorous physical activity. No other significant relationships were observed. CONCLUSION: Glycemic control was a significant predictor of SB level. Understanding these relationships are important in designing and implementing interventional programs. Future studies are needed to explore this relationship further, as both glycemic control and SB are modifiable factors and could be used as main target for interventions aimed to improve health outcomes in people with T2D.
