The prevalence of low back pain in the elderly. A systematic review of the literature.

Abstract

The prevalence of low back pain in the older population (> = or 65 years) was reviewed in an analysis of the literature from 1966 to the present. To determine the prevalence of low back pain in the geriatric population. Back pain is one of the most frequently reported conditions affecting the adult population. However, the prevalence of low back pain in the older age population is not accurately known. A methodologic search of five computerized bibliographic databases was performed to identify citations on the prevalence of low back pain in the elderly. Data were summarized, and prevalence studies were critically appraised in detail for their quality. There is wide variability in the reported prevalence of back pain. Many factors have been proposed to explain these findings including sample source, study design, definitions of back pain, and use of patient-reported data. Comorbidity among older patients also contributes to the variability in the reporting of prevalence of back pain. There is an under-representation of the older population in the back pain literature. The data in the current study suggest that the prevalence of low back pain in this population is not known with certainty and is not comparable with that in the younger population. The authors stress the need for future studies to improve the reporting of age information to make prevalence studies more informative and applicable.
