StandUPTV Habits for keeping evening sedentary screen time lower
StandUPTV Habits: Feasibility Trial for Maintaining Reductions in Sedentary Screen Time
This program will try a smartphone app that sends alerts to help adults at risk for type 2 diabetes break up long evening screen sessions and keep screen time lower.

What this trial studies
This Phase II pilot uses a habit-formation mHealth approach to maintain reductions in evening sedentary screen time over 12 months in a nationally recruited sample of adults at risk for type 2 diabetes. Participants who are insufficiently active and report >3 hours of daily sedentary screen time will use the StandUPTV app, which triggers an alert after about 30 minutes of evening screen time to prompt a non-sedentary response. The study leverages commercially available screen-time monitoring tools, randomization to study conditions, and device-based outcome measures including activPAL and continuous glucose monitoring during assessment periods. Findings will inform a future fully powered Phase III trial testing whether sustained reductions in evening screen time improve metabolic and cardiovascular risk factors.
Who should consider this trial
Good fit: Adults who do not meet the 150 minutes/week MVPA guideline, report more than 3 hours of sedentary screen time per day, use an Android 8.0+ phone, have home broadband or unlimited data, are willing to use the app and wear activPAL and CGM devices, and do not have diagnosed diabetes or major illnesses are ideal candidates.
Not a fit: People with diagnosed diabetes or major medical conditions that limit activity, current smokers, those who already meet activity guidelines or have low evening screen time, or people unwilling to use an Android phone, the app, or wearable devices are unlikely to benefit.
Why it matters
Potential benefit: If successful, the app could help people sustain lower evening screen time, increase non-sedentary behavior, and potentially improve sleep and metabolic risk factors linked to diabetes and heart disease.
How similar studies have performed: Prior pilot work with StandUPTV and other mHealth prompting studies have shown promise in reducing evening screen time and sedentary behavior, but long-term maintenance using habit-based strategies is still relatively unproven.
