A cohort of 38-year-old men and women were studied for leisure time physical exercise in relation to low back pain (LBP), education, work, social class and smoking by a self-administered questionnaire. At the age of 14 years, the subjects had been interviewed by their school doctor regarding history of LBP and radiographs of the thoracic and lumbar spine were taken. The results show no positive correlation between radiographic changes and LBP in the adolescent period and decreased physical activity in adulthood. ⋯ Our results show a falling interest in participating in sports activities over time, with 68% of the subjects being members of an athletic association previously, but only 29% currently. Women were more physically inactive during leisure time, probably because of their dual role. Logistic regression analysis indicates that physical activity is related to a long school education, high social class and regular sports activity over time.

This cross-sectional study compares the Oswestry and Roland-Morris disability scales in two groups of patients with low back pain of different clinical and electromyographic severity. ⋯ The authors conclude that both functional disability scales accurately discriminated between these two groups of patients with low back pain of very different clinical and electromyographic severity.
