Abstract

BackgroundLumbar spondylosis is more prevalent among the middle-aged and elderly, but few population-based studies have been conducted, especially in Japan. The purpose of this study was to explore the prevalence of lumbar spondylosis and its associations with low back pain among community-dwelling Japanese women.

MethodsLateral radiographs of the lumbar spine were obtained from 490 Japanese women ≥ 40 years old, and scored for lumbar spondylosis using the Kellgren-Lawrence KL grade at lumbar intervertebral level from L1-2 to L5-S1. Height and weight were measured, and body mass index BMI was calculated. Low back pain in subjects was assessed using a self-administered questionnaire. Stiffness index bone mass was measured at the calcaneal bone using quantitative ultrasound.

ResultsPrevalence of radiographic lumbar spondylosis for KL ≥ 2, KL ≥ 3 and low back pain were 76.7%, 38.8% and 20.0%, respectively. Age was positively associated with radiographic lumbar spondylosis KL = 2, KL ≥ 3 and low back pain. Greater BMI was associated with lumbar spondylosis with KL = 2, but not with KL ≥ 3. Stiffness index was associated with neither radiographic lumbar spondylosis nor low back pain. Multiple logistic regression analysis identified radiographic lumbar spondylosis KL ≥ 3 at L3-4, L4-5 and L5-S1 was associated with low back pain, independent of age, BMI and stiffness index.

ConclusionSevere lumbar spondylosis at the middle or lower level may contribute to low back pain.
