What is the purpose of this trial?

This trial aims to develop strategies to reduce sedentary behavior (sitting for long periods) in Black adults aged 55 and older with Type 2 Diabetes (T2D). The research focuses on understanding how sitting affects health and finding ways to encourage more movement, which can improve heart health and better manage diabetes. Participants will collaborate using Collaborative Solutions for Breaking up Sedentary Time to identify and try different methods to interrupt prolonged sitting. The trial specifically seeks Black adults with T2D who are interested in exploring new ways to be more active in their daily lives. As a Phase 2 trial, the research measures how well the treatment works in an initial, smaller group, offering participants a chance to contribute to potentially impactful health solutions.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. Please consult with the study team for guidance.

What prior data suggests that these strategies to reduce sedentary time are safe for Black adults with Type 2 Diabetes?

Research shows that taking breaks from long periods of sitting benefits health. Lab studies have found that standing up and moving around quickly improves blood sugar levels and heart health. This approach is generally safe and easy to implement.

Less information exists on how this method specifically affects Black adults with type 2 diabetes. However, past studies have not raised major safety concerns about the general idea of moving more and sitting less. Since this trial is in an early stage, it primarily focuses on assessing the method's safety and effectiveness.

In summary, while more research is needed for this specific group, current evidence suggests that taking breaks from sitting is likely safe and may offer health benefits. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the "Collaborative Solutions for Breaking up Sedentary Time" approach because it offers a fresh way to tackle Type 2 Diabetes (T2D) by focusing on reducing sedentary behavior, especially for Black adults aged 55 and older. Unlike standard treatments that usually involve medication or diet changes, this method emphasizes breaking up long periods of sitting with active movement. This behavioral strategy could lead to more sustainable lifestyle changes and potentially improve blood sugar control without relying solely on medication. By targeting sedentary habits directly, this approach hopes to address a significant but often overlooked factor in managing T2D.

What evidence suggests that this trial's strategies could be effective for reducing sedentary time in Black adults with Type 2 Diabetes?

Research shows that taking breaks from long periods of sitting can quickly improve health markers related to type 2 diabetes, such as blood sugar levels and blood vessel health. Studies have found that reducing daily sitting time can help manage type 2 diabetes by enhancing blood sugar control. Even short breaks from sitting can improve heart and metabolic health, which are crucial for people with type 2 diabetes. Programs that focus on reducing sitting time encourage more active lifestyles, leading to healthier outcomes. In this trial, participants will engage in "Collaborative Solutions for Breaking up Sedentary Time," which involves working together on plans and strategies to reduce sitting time and increase physical activity. ^{1 2 6 7 8}

Published Research Related to This Trial

A 24-week behavioral modification program using pedometers and telephone support significantly increased physical activity by an average of 2744 steps per day and reduced sedentary behavior by 23 minutes per day in type 2 diabetes patients.

These positive changes in physical activity and reduced sedentary time were still evident one year later, with an increase of 1872 steps per day and a decrease of 12 minutes in sedentary behavior, demonstrating the program's lasting impact.

The effects of a pedometer-based behavioral modification program with telephone support on physical activity and sedentary behavior in type 2 diabetes patients. De Greef, KP., Deforche, BI., Ruige, JB., et al.[2022]

Increased sedentary time, or 'sitting time', is a significant factor in the development and worsening of type 2 diabetes (T2D), highlighting the need for effective prevention strategies.

The review raises the question of whether reducing sitting time could serve as a beneficial treatment for T2D, suggesting that lifestyle changes may play a crucial role in managing the disease.

Type 2 diabetes sits in a chair. Solomon, TP., Thyfault, JP.[2018]

The multicomponent technology intervention significantly reduced daily sedentary time by an average of 58.7 minutes per day among 40 overweight university employees over a 12-week period, indicating its efficacy in promoting physical activity.

Participants engaged well with the intervention, using the provided tools like the pedal machine and online program, which suggests that such technology-based approaches could be effective in reducing sedentary behavior in workplace settings.

Multicomponent intervention to reduce daily sedentary time: a randomised controlled trial. Carr, LJ., Karvinen, K., Peavler, M., et al.[2022]

A randomized controlled trial involving 187 young adults at risk of type 2 diabetes showed that a structured education workshop aimed at reducing sedentary behavior did not lead to significant changes in sitting time after 12 months.

The lack of effectiveness may be attributed to the brief nature of the intervention and a possible misfocus on increasing physical activity rather than specifically reducing sitting time.

Sedentary behavior, defined as sitting, is a significant risk factor for various chronic diseases, including type 2 diabetes, cardiovascular disease, and certain cancers, even when accounting for physical activity levels.

Breaking up prolonged sitting with light movement or substituting sitting with standing can improve glucose regulation, suggesting that reducing sedentary time is crucial for managing and preventing type 2 diabetes.

Experimental studies support the idea that reducing and breaking up sedentary time can lower the risk of type 2 diabetes (T2D), aligning with previous epidemiological evidence.

New findings are prompting updates to diabetes-related physical activity guidelines, emphasizing the importance of not just engaging in moderate-vigorous exercise, but also minimizing and interrupting prolonged sitting throughout the day.

The study demonstrated that sedentary behavior counseling significantly reduced total sitting time from an average of 11.8 hours to 10.29 hours over three months in 10 adults with type 2 diabetes, indicating the intervention's effectiveness.

Participants also experienced a notable improvement in glycemic control, with a decrease in HbA1c levels by 0.51%, suggesting that reducing sedentary behavior can positively impact diabetes management.

The randomized controlled trial (RCT) involving 71 young adults at high risk for type 2 diabetes found no significant reduction in sedentary behavior after a 12-month intervention, despite positive feedback on the educational workshops.

Barriers to reducing sedentary time included a lack of perceived health risk, preference for active behaviors, motivational drift after initial follow-ups, and issues with the self-monitoring tool, suggesting that future interventions should enhance participant engagement and address these challenges.
