Vertebral endplate changes are not associated with chronic low back pain among Southern European subjects: a case control study.

ABSTRACT:

Background and purpose

Data on the association between vertebral endplate changes and low back pain are contradictory. This study was designed to assess whether this association exists among Southern European subjects.

Materials and methods

Patients in this study serving as cases were 35-50 years of age with low back pain lasting >90 days, for whom a lumbar MR imaging had been prescribed. Controls were subjects 35-50 years of age, having a cranial MR imaging for headache with normal findings, and no history of clinically relevant LBP. Two hundred forty cases and 64 controls were recruited consecutively in the radiology services across 6 cities in Spain. Imaging findings and subject characteristics were gathered through previously validated instruments. Radiologists who interpreted MRI were blinded to the subject characteristics. A multivariate logistic regression model was developed to assess the association of vertebral endplate changes with LBP, adjusting for sex, age, body mass index, lifetime exposure to smoking, physical activity, disk degeneration, and the interaction between disk degeneration and vertebral endplate changes.

Results

Vertebral endplate changes were found in 80.4% of the cases and in 87.5% of the controls. In the regression model, disk degeneration was the only variable showing a confounding effect. Results showed that after adjusting for disk degeneration, the presence of vertebral endplate changes is associated with the absence of chronic LBP (OR for LBP: 0.31; 95% CI, 0.10-0.95).

Conclusions

In Southern European subjects, vertebral endplate changes are not associated with chronic LBP.

Project description:ObjectiveThis study assessed associations between severity of, and prescription medication use for, chronic low back pain (CLBP) and health-related quality of life, health status, work productivity, and healthcare resource utilization.MethodsThis cross-sectional study utilized SF-12, EQ-5D-5L, and work productivity and activity impairment (WPAI) questionnaires, and visits to healthcare providers among adults with self-reported CLBP participating in the National Health and Wellness Survey in Germany, France, UK, Italy, and Spain. Respondents were stratified into four groups according to pain severity (mild or moderate/severe) and prescription medication use (Rx-treated or Rx-untreated). Differences between groups were estimated using generalized linear models controlling for sociodemographics and health characteristics.ResultsOf 2086 respondents with CLBP, 683 had mild pain (276 Rx-untreated, 407 Rx-treated) and 1403 had moderate/severe pain (781 Rx-untreated, 622 Rx-treated). Respondents with moderate/severe pain had significantly worse health-related quality of life (SF-12v2 physical component summary), health status (EQ-5D-5L), and both absenteeism and presenteeism compared with those with mild pain, including Rx-untreated (moderate/severe pain Rx-untreated vs. mild pain Rx-untreated, p ≤ 0.05) and Rx-treated (moderate/severe pain Rx-treated vs. mild pain Rx-treated, p ≤ 0.05) groups. Significantly more visits to healthcare providers in the last 6 months were reported for moderate/severe pain compared with mild pain for Rx-treated (least squares mean 13.01 vs. 10.93, p = 0.012) but not Rx-untreated (8.72 vs. 7.61, p = 0.072) groups. Health-related quality of life (SF-12v2 physical component summary) and health status (EQ-5D-5L), as well as absenteeism and presenteeism, were significantly worse, and healthcare utilization was significantly higher, in the moderate/severe pain Rx-treated group compared with all other groups (all p ≤ 0.05).ConclusionGreater severity of CLBP was associated with worse health-related quality of life, health status, and absenteeism and presenteeism, irrespective of prescription medication use. Greater severity of CLBP was associated with increased healthcare utilization in prescription medication users.
