Association between physical activity and stress among Portuguese Anaesthetists

Abstract

Introduction

Anaesthetists face significant daily stress, which can impact their health and clinical performance. While regular physical exercise has been shown to reduce stress, there is a lack of research on this topic among Portuguese anaesthetists. This study aims to: (1) assess physical activity and perceived stress levels among Portuguese anaesthetists and establish a relationship between them in this group, and (2) identify potential professional or personal barriers to exercise.

Methods

This cross-sectional study used an anonymous online survey distributed to Portuguese anaesthetists registered with the Portuguese Society of Anaesthesiology. The questionnaire collected sociodemographic data and included the short form of the International Physical Activity Questionnaire (IPAQ) and the Perceived Stress Scale (PSS-10).

Results

A total of 252 participants were analysed. The majority (49.2 %) engaged in moderate physical activity; 24.2 % reported high levels, and 26.6 % had low levels. Most participants (57.1 %) reported moderate stress, 34.1 % low stress, and 8.7 % high stress. A weak negative correlation was found between physical activity and stress (rho = −0.187, p = 0.003), suggesting higher physical activity may be associated with lower stress. However, ANOVA did not show significant differences in stress levels across activity categories (p = 0.0732).

Conclusions

Although a weak inverse correlation was observed, findings suggest physical activity alone may not determine stress levels. Given the high workload and burnout risk, institutional strategies promoting well-being, such as structured exercise programmes and workload management, should be considered.
