T1D Closed-loop and Physical Activity

June 11, 2024 updated by: Centre Hospitalier Universitaire de Nice

"Impact of an Automated Closed-loop Insulin Infusion System on Adherence to Physical Activity in Patients With Type 1 Diabetes "

"Physical activity is recognized as beneficial for patients living with type 1 diabetes (T1DM), with a demonstrated effect not only on HbA1c control [1] but also on reducing the incidence of diabetes-related complications [2,3]. It is recommended that patients living with T1DM perform 150 minutes of accumulated physical activity per week, without exceeding two consecutive days without physical activity [4]. Indeed, one meta-analysis reported that moderately vigorous activity (≥4.5 METs) was beneficial compared with lower-intensity activity, while three other studies noted that only vigorous physical activity (≥6 METs) predicted lower all-cause mortality rates [5]. However, T1DM can represent a major obstacle to physical activity because of the occurrence of fairly frequent hypoglycemia, including after physical effort, the need for early resugaring but also the risk of hyperglycemia (rebound or with certain activities) [6]. The advent of automated insulin delivery systems has led to a significant improvement in time on target and a reduction in the frequency of hypoglycemia, including during physical activity in some studies [7-9]. The aim of this study is therefore to evaluate, in a cohort of patients with T1DM, whether the implementation of a closed-loop automated insulin delivery system increases physical activity in patients with T1DM. Based on the interpretation of the ONAPS-PAQ [10], the investigator hypothesize that the implementation of the closed-loop system enables an individual to reach the 3000 MET/min/week threshold (considered ""Active+"" from this threshold onwards).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
IPAQ score
Time Frame: At the inclusion
"Measurement of IPAQ in METs/min/week (reflects the amount of physical activity practised using a validated questionnaire). There are seven items whose the result corresponds to the sum of the given figures. "
At the inclusion

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
BAPAD-1 score "
Time Frame: At the inclusion
The BAPAD-1 score, validated in French, will be used to assess the usual obstacles to physical activity in T1DM. It is a Likert scale (between 0-7) composed by twelve items. Then, a mean is calculated with all the answers.
At the inclusion
BREQ-2
Time Frame: At the inclusion
"To assess motivation to engage in physical activity, use the BREQ-2 score, validated by ONAPS. It is a Likert scale (between 0-7) composed by six items. Then, a mean is calculated with all the answers.
At the inclusion
ONAPS PAQ
Time Frame: At the inclusion
To assess sedentary behaviour, use the ONAPS PAQ score with only the sedentary behaviour section. 4 items. Then the sum of the results is calculated
