Low Back Pain (LBP) is commonly reported as a very frequent disorder in sports, but its prevalence in runners remains unclear.
To determine the prevalence of LBP in a wide sample of Italian runners.
A cross-sectional online survey.
A national survey, according to the CHERRIES and STROBE guidelines, was performed in 2019.
2539 Italian runners.
A sample of Italian runners registered with national running associations was recruited. The survey was conducted using an online survey development platform. The questionnaire was self-reported and included 38 questions.
Descriptive statistics and frequencies were used to analyze results. Relationships between demographics, daily habits and running characteristics and the responses given was calculated with Cramer’s V. Only correlation values higher >0.60 were deemed of interest.
2539 questionnaires (63.5%) were valid for analysis. In total, 22.6% of runners reported having experienced LBP in the past year. Most participants (77.0%) reporting episodes of LBP believed it was not caused by running. No significant correlations (Cramer’s V < 0.60) were found between LBP and demographics, training characteristics or lifestyle habits.
The prevalence of LBP among Italian runners was 22,57%. LBP was not associated with training, equipment or lifestyle.
