RESUMO
The purpose of this study was to evaluate as accurately as possible, in a well-defined population subgroup, the prevalence and incidence of lower back pain, the impact of this symptom on professional activities and personal life, and the influence of risk factors. Members of the medical profession were considered particularly apt to accurately and reliably report their personal experience with lower back pain and were therefore selected for this survey. Five hundred 93-item questionnaires were sent to a representative sample of physicians in the Maine-et-Loire district, France. Response rate was 93%. Prevalence of lower back pain at the time of the survey was 32% and cumulative prevalence was 62%. Static spinal disorders (exaggerated lordosis, scoliosis, unequal length of lower limbs) and injury to the spine were found to be risk factors. Occupation-related stresses to the spine reported as being responsible for lower back pain included bending forward for prolonged periods, lifting weights, driving, and prolonged sitting.
