Trial Summary

What is the purpose of this trial?

Adherence refers to how well a person follows a recommended and agreed-upon course of action. Adherence is necessary for desired clinical outcomes and can include attending appointments, making lifestyle changes, and following home-based regimens for themselves or someone for whom they care for. Adherence to home exercise programs can be as low as 50%, directly impacting program effectiveness. There are many reasons why an individual may struggle to adhere, which may include perceived barriers such as not having enough time, reduced self-efficacy, the belief that the program is ineffective, or seeing early positive results so they then feel they do not need to continue with the program. For children, low skill level and lack of parental support are additional barriers to program adherence. A Sequential Multiple Assignment Randomized Trial (SMART) intervention is an intervention design that guides the adaptation of treatments over time. Adaptation refers to the use of dynamic information about a person (or family) to decide whether and how to intervene. SMART interventions are intended to address the unique and changing needs of individuals. The proposed study will examine the feasibility of using a 12-week (60-day) adaptive intervention design to optimize child adherence to a home exercise program. To advance equitable adherence to home exercise programs, there is a pressing need to develop strategies that support all children and families. The proposed study will provide new knowledge regarding the utility of adaptive interventions to optimize participation engagement in behavioral interventions in community contexts.

Do I have to stop taking my current medications to join the trial?

Yes, if you are currently taking medications like iron, metformin, or chemotherapeutic agents that could impact your ability to engage in physical activity, you will not be eligible to participate in the trial.

What data supports the idea that Physical Activity for Sedentary Lifestyle is an effective treatment?

The available research shows that interrupting prolonged sitting with physical activity can be beneficial for health. For example, a study on overweight and obese adults found that breaking up sitting time was feasible and could be measured effectively. Another study focused on older adults, who tend to sit the most, and explored different strategies to interrupt sitting time, suggesting potential health benefits. Additionally, a study involving older adults at risk of heart disease found that combining exercise with a technology-based intervention to reduce sitting time could improve health outcomes like blood pressure and waist circumference. These findings indicate that reducing sitting time and increasing physical activity can be an effective treatment for improving health.12345

What safety data exists for the treatment of reducing sedentary behavior?

The provided research does not directly address safety data for the specific treatment of reducing sedentary behavior, such as the InPACT at Home study. However, it highlights the health risks associated with prolonged sitting and the potential benefits of interventions aimed at reducing sitting time. The studies emphasize the need for well-designed trials to test the efficacy and safety of such interventions, but specific safety data from these trials is not detailed in the abstracts provided.35678

Is the treatment 'Interrupting Prolonged Sitting With ACTivity (InPACT) at Home' a promising treatment for a sedentary lifestyle?

Yes, the InPACT at Home treatment is promising because it focuses on reducing sitting time, which is important for health. Studies show that sitting too much can harm your heart and metabolism, even if you exercise regularly. By encouraging breaks from sitting, this treatment can help improve health and reduce risks associated with a sedentary lifestyle.89101112

Eligibility Criteria

This trial is for individuals who struggle with sticking to home exercise programs, possibly due to time constraints, low confidence in their abilities, or doubts about the program's effectiveness. It aims to help those who start exercising but stop when they see early results or think it's not necessary anymore. Children participating need parental support.

Inclusion Criteria

Participants must have access to a computer and internet at home
I am a child aged 8-12 from Michigan, or I am their parent/guardian.
Participants must be proficient in English

Exclusion Criteria

Potential participants who are ineligible will be informed during their screening call and will not be enrolled.
Children answering 'YES' to any question on the Physical Activity Readiness Questionnaire (PAR-Q)22 indicating heart condition, high BP, chest pains, dizziness during daily activities, or requiring a doctor's recommendation for supervision during exercise
My child has a disability that requires adult help for communication and following instructions.

Interventions

  • Interrupting Prolonged Sitting With ACTivity (InPACT) at Home Optimization Study
Trial Overview The study tests a new way of keeping people on track with their home exercises using a SMART intervention over 12 weeks. This method adapts the exercise plan based on how well someone is doing and tries to make sure that each person gets the right kind of encouragement and changes needed over time.

Findings from Research

A pilot study involving 30 older adults (ages 50-70) showed that reducing daily sitting time by 2 hours was feasible and effective, while increasing sit-to-stand transitions did not change overall sitting time.
Participants in the sit-to-stand transition group successfully increased their transitions, indicating that specific behavioral goals can be targeted to reduce sedentary behavior in older adults.
Two-Arm Randomized Pilot Intervention Trial to Decrease Sitting Time and Increase Sit-To-Stand Transitions in Working and Non-Working Older Adults.Kerr, J., Takemoto, M., Bolling, K., et al.[2022]
This study aims to evaluate the effectiveness of combining structured exercise with a technology-based intervention to reduce sedentary behavior in older adults at risk for cardiovascular disease, addressing a significant public health concern.
By focusing on participants aged 60 and older with moderate to high risk of coronary heart disease, the research will assess various health outcomes, including daily activity patterns and cardiovascular function, to inform future large-scale trials.

A 1-week intervention using hourly prompts and behavioral strategies successfully reduced sitting time by an average of 1.85 hours per day in overweight/obese adults, while also increasing standing and stepping time.
Despite the reduction in sitting time, participants did not increase the frequency of sit/stand transitions, indicating a preference to remain standing longer rather than frequently interrupting sitting, which may inform future intervention designs.
