A multicentric, non-interventional study using a clinical questionnaire (SAPHIR) and activity monitor (Activ-PAL) to estimate the level of physical activity in the general population.

This study compares the level of physical activity reported by the SAPHIR questionnaire with the activity recorded by the activity monitor during the same period, in order to determine if the SAPHIR score is able to represent the measured physical activity, in a simple and easily calculable manner.

Hypothesis:

The aim of this work is to propose a new questionnaire that is simple to complete by the patient,quick to analyse and directly calculable by the doctor and adapted to the general population, whether during the initial evaluation or the follow-up.

Indeed, these scores are rarely used outside the context of the prescription of physical activity in specialized centers. Moreover, a tool suited to the constraints of community medicine seems necessary, given the growth of the prescription of physical activity in primary care.

The idea behind this new questionnaire is to obtain a score ranging from 0 to 100 that can be calculated through simple mental arithmetic, which is not the case for most existing questionnaires, in particular the IPAQ.

Promotion of physical activity has been an important public health issue in France for around ten years, as demonstrated by numerous reports and public health plans 'qui ont vu le jour" with this aim. (Plan national nutrition santé PNNS 2011-2015 ; Plan obésité PO 2010-2013 ; Plan cancer 2014-2019). In order to continue promoting physical activity (PA), it is necessary to have a well-adapted, simple and rapid tool is that allows precise evaluation and monitoring within the general population.

Currently, the French National Authority for Health (la Haute Autorité de Santé), through its guide for the promotion, consultation and medical prescription of physical and sports activity for health in adults, updated in July 2022, proposes an estimate of the "usual level of PA (…) using the two-question Marshall questionnaire (30 seconds)" or alternatively, "it can be calculated more precisely with the Global Physical Activity Questionnaire (GPAQ), a 16-question self-administered questionnaire that patients can complete online at www.mangerbouger.fr."

The GPAQ is one of the most widely used questionnaires. While its strength lies in its precision, it is long to complete and score. Therefore, despite being validated by many studies, it is not practical for routine use. In practice, the "Ricci and Gagnon" questionnaire is used for the follow-up of patients, using tracking logs. (Sport santé sur ordonnance. Contexte et exemples de mise en oeuvre. Octobre 2017. ONAPS) . This categorizes individuals as inactive, active or very active, and has never been scientifically validated in a study, to the best of our knowledge.

Finally, the International Physical Activity Questionnaire (IPAQ) is a test validated both in long and short forms. It allows a precise calculation of the amount of physical activity expressed in MET (metabolic equivalent)/min/week but does not provide information on its distribution throughout the week. Like the GPAQ, with 27 different questions it is also lengthy to complete, making it impractical for routine use. The short version tends to underestimate physical activity levels, and the final score cannot be easily calculated in real time. Nevertheless, this version will be used as a reference.

The aim of this work is to propose a new questionnaire that is simple for patients to complete, quick to analyse, can be calculated directly by the doctor, and is adapted to the general population, whether for an initial assessment or a follow-up.

Moreover, the prescription of physical activity is usually carried out over short, renewable periods, whereas long-term changes are necessary to achieve significant improvements in morbidity and mortality.

The developed questionnaire ultimately aims to be useful for monitoring the evolution of physical activity.

Inclusion criteria:

• Patients referred for a consultation at one of the participating centers
• Patients over 18 years old with no upper age limit

Non-inclusion criteria:

• Patients with a contra-indication to walking
• Professional athletes or patients participating in endurance sports competitions
• Patients refusing to participate in the study
• Patients unable to understand the objectives or instructions of the study

Exclusion criteria:

-Patients with Activ-PAL recordings of less than 3 days

The study population consists of patients referred for consultation in the department of sports medicine (generally active patients, although patients may also be sedentary and/or inactive) or in the department of vascular medicine (patients with lower limb peripheral artery disease, mostly inactive)

Data will be shared upon reasonable request. Only de-identified data will be shared. Any data collected during the study may be shared. The protocol will be shared initially. Other documents may be shared at a later date upon request (e.g., the CRF to allow a collaborator to select the data they wish to access). The recipients of the data will be researchers. The data will be available for any purpose deemed relevant by the study investigator, based on a protocol provided by the requester, after verification of the obtaining of regulatory approvals, including the favorable opinion of an ethics committee.

The data will be shared after signing a negotiated data transfer agreement ( data access agreement), for the duration specified in the agreement.

The data will be made available via secure transfer (sharing platform approved by the university hospital: BlueFiles or Oodrive).
