Sammendrag Background: Physical activity in leisure time is often considered to have favourable effects on the risk of low back pain LBP , but demonstrating a definite association in epidemiological studies has proven difficult. The purpose of the present study was to explore associations between physical activity and risk of chronic LBP in an adult population and to investigate whether relationships are limited to certain age groups or to females or males.
A particular objective was to determine whether support could be found for a U-shaped relationship, with both low and high activity levels carrying greater risk. Participants were women and men without LBP at baseline, who reported after 11 years whether they suffered from LBP.
Associations between baseline physical activity in leisure time and risk of chronic LBP at end of follow-up were evaluated by generalized linear modelling with adjustment for potential confounders.
Results: Significant associations between leisure time physical activity and risk were observed in both sexes after age adjustment, mainly suggesting inverse relationships. The corresponding RR in men was 0. After adjustment for education, employment, occupational activity, body mass index BMI and smoking, significant relationships could only be demonstrated in those aged 50 years or more at baseline.
