Comparing Objective and Subjective Physical Activity Assessments in Obese Patients

Austria23 participantsStarted 2020-05-01

Plain-language summary

The goal of this observational study is to analyze the validity of self-reported physical activities in obese patients with psychosomatic disorders in a clinical setting. The main question aims to answer: \- How valid are self-reported physical activity data (via the International Physical Activity Questionnaire, IPAQ-SF) compared to actigraphy-based objective measurements (using the SenseWear® armband, SWA)? Between 2020 and 2022, 23 patients with obesity (21 anorexia nervosa, 2 bulimia nervosa) were recruited from an Austrian psychosomatic clinic. Receiving routine care, participants were additionally asked to * wear the SWA for seven days in the clinic * complete the IPAQ-SF for the same reference period on the first weekday after SWA wearing time The study then statistically compared total physical activity, measured in so called metabolic equivalents (MET minutes per week), and sitting time (minutes per day) between the two methods to determine the accuracy of the self-reported data.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

What they're measuring

MET (Metabolic equivalents) - Objective measure of physical activity in MET min/week (by SWA)

Timeframe: Period: SWA was worn for at least four days within week 3 or week 4 of clinical stay

MET (Metabolic equivalent) - Subjective measure of physical activity in MET min/week (by IPAQ self-report)

Timeframe: Single time point: Retrospective self-report on the first weekday after SWA wearing time
