Abstract
High workloads and extended work shift greatly limit the opportunities for medical residents to adopt a healthy lifestyle by practicing regular physical exercise. Using data from the Public Health Residents' Anonymous Survey in Italy (PHRASI), this research assessed the associations between physical activity levels and sedentary behavior, well-being, and self-rated health among Italian public health residents (PHRs) during the COVID-19 pandemic. Employing a cross-sectional design, this study utilized the International Physical Activity Questionnaire, the WHO-5 Well-being Index, and the single-item self-rated health to measure physical activity, sedentary behavior, self-rated health, and well-being among PHRs. The study included 379 PHRs. Multiple logistic regressions adjusted for age and sex were applied to explore the associations among the variables of interest. While 74% of PHRs were sufficiently active, 50% reported good well-being. We found a positive association between physical activity (specifically walking and intense activities) and well-being (aOR 1.292, p = 0.032). At the same time, sedentary behavior was negatively associated with self-rated health (aOR 0.948, p = 0.022) and well-being (aOR 0.945, p = 0.005). This study contributes valuable insights into the role of physical activity and sedentary behavior in PHRs' mental health, calling for targeted public health strategies to support their well-being.
