High prevalence of diffuse idiopathic skeletal hyperostosis (DISH) among obese young patients – A retrospective observational study
Authors' conclusion
The prevalence of DISH among obese young patients was 18 %, which is much higher than in the general population.
Study context
- Population
- Young (31–50 years) patients with BMI≥35 visiting the bariatric ambulatory clinic of an academic medical center, 2013–2022118 females, 64.2 %
- Participants
- 183 participants
- Exposure
- DISH vs non-DISH
- DISHn = 33
- Outcome
- Prevalence of DISH (Resnick criteria)
Methodological detailssingle academic medical centre, radiographic review
- Single academic medical centre
- Radiographic review
Main finding
As reported in the abstract
Prevalence of DISH
- Significantly higher than the expected 10 % (Z = 3.62)
- p<.001
Observational data: associations, not effects.
Further findings
| Outcome | P value |
|---|---|
| Comorbidities, DISH vs non-DISH (significantly higher prevalence in DISH)DISH vs non-DISH | χ2 = 8.30, p<.004 |
| Comorbidities, DISH vs non-DISH (significantly higher prevalence in DISH)DISH vs non-DISH | χ2 = 4.69, p<.03 |
| Comorbidities, DISH vs non-DISH (significantly higher prevalence in DISH)DISH vs non-DISH | χ2 = 6.16, p<.013 |
- Age, DISH vs non-DISH — Prevalence of DISH increased by age (linear association=14.95) · DISH patients significantly older
- P < 0.001 · t = 4.54, p<.001
"Near DISH" (not yet fulfilling the Resnick criteria)
- 8 patients (4.4 %), 95 % CI 2.2-8.4 %
