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. ⋯ 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.
