Potential Impact of Physical Activity on Measures of Well-Being and Quality of Life in People with Rare Diseases: A Nationwide Cross-Sectional Study in Italy.

Background: Rare diseases constitute a heterogeneous group of approximately 7000-8000 conditions, distinguished by their low prevalence. Collectively, they present a significant global health challenge, affecting millions of people worldwide. It is estimated that rare diseases affect approximately 10% of the global population, which places a significant burden on individuals, families, and society. It is, therefore, important to consider strategies to improve the overall well-being and quality of life of individuals with rare diseases. One potential avenue for exploration is the incorporation of physical activity (PA). The scope of this study was to ascertain whether PA has a positive impact on measures of well-being and to determine its potential to enhance the quality of life of these individuals.

Methods: The data were collected via an online survey. The one-way ANOVA test for multiple groups and multivariate Poisson models were employed to identify the significant predictors of the outcomes of interest.

Results: The protective effects of PA become evident with a minimum of six hours of activity per week. Our data confirm that the weekly hours devoted to PA can serve as a significant protective factor for QoL. The study also provided some insights into the motivations behind patients' engagement in PA. These included improving QoL and physical well-being, as well as the desire to interact socially, with the goal of meeting friends or making new acquaintances. Finally, for adults and older adults, engaging in PA can also be a way to control weight.

Conclusions: It is becoming increasingly clear that individuals with rare diseases stand to benefit greatly from PA, so it is only sensible to educate them on the advantages of an active lifestyle.
