Takeaway

  • Patients with low back pain (LBP) were 56% more likely to develop first-onset temporomandibular disorder (TMD) than those without back pain in this countrywide insurance database analysis.

Why this matters

  • The results of this study, with a 15-year follow-up, suggest that clinicians treating patients for 1 condition should screen for the other.

Study design

  • This study identified patients newly diagnosed with LBP (N=65,121) from Taiwan’s National Health Insurance Research Database.
  • Funding: Tri-Service General Hospital Research Foundation.

Key results

  • The overall adjusted HR for TMD occurrence in the LBP group was 1.561 (P<.001>
  • Vs older patients aged 60-70 years, higher incidences for TMD were noted in those:
    • Aged 20-29 years: aHR 5.615 (P<.001>
    • Aged 30-39 years: aHR, 2.406 (P=.001).
  • Higher incidence was also seen among patients with higher vs lower insurance premiums:
    • aHR for 18,000-34,999 NT, 12.741.
    • aHR for ≧35,000 NT, 33.684 (Pboth<.001>
  • Osteoporosis was a risk factor contributing to TMD occurrence: aHR,1.860 (P=.003).

Limitations

  • The actual prevalence of TMD might have been underestimated.
