Physical activity prescription in general practice in France: where do we stand? A cross-sectional study.

Background: Physical activity on prescription (PAP) is recognized as an effective preventive and therapeutic tool for various diseases, yet its application by general practitioners (GPs) varies widely. This study aims to analyse PAP usage practices among GPs in France, focusing on prescription frequency, targeted pathologies, and influencing factors. It also explores GPs' perceptions of facilitators and barriers to PAP.

Methods: A cross-sectional study was conducted between October 23, 2023, and April 23, 2024, collecting data from a sample of GPs across France. A structured questionnaire was used to assess the frequency of PAP usage, target populations, as well as GPs' knowledge and perceived barriers to prescribing PA. Descriptive and analytical methods were employed to analyse the data, and logistic regression was used to examine associations between physician characteristics, PAP practices, and key barriers to prescribing.

Results: Among respondents, 39.1% reported prescribing PAP, with a median prescription rate of approximately twice per month. Reduced sedentary behaviour (< 4 h) was significantly associated with a higher frequency of PAP (pOR 3.6, p = 0.044). Knowledge of a nearby sport-health facility strongly predicted prescription (pOR 3.7 p < 0.001). Prescription support tools positively influenced prescribing rates (pOR 1.6 p = 0.041). In contrast, GPs unaware of any tools prescribed significantly less.

Conclusion: These findings suggest that improving access to sport-health facilities and providing GPs with effective support tools could significantly enhance PAP practices.
