The study aims to describe the influence of sports activities, high body weight and smoking on low‐back pain. The results were obtained from a population‐based case‐referent study, the Musculoskeletal Intervention Center (MUSIC)‐Norrtälje study. In all, 342 male and 449 female cases, and 662 male and 948 female referents participated. Neither low‐intensity training many hours/week (>=5 h) nor high‐intensity training few (1–2 h), intermediate (3–4 h) or many hours (>=5 h) per week affected the risk of low‐back pain among men. Few (1–2) hours with high‐intensity training increased the relative risk of low‐back pain among women, RR 1.6 (1.1–2.4). An increased risk of low‐back pain was found for men with high body weight, RR 2.2 (CI 1.2–3.9) but not for women. Smoking did not influence the risk of low‐back pain.
