Hypothesis
Is there an association between leptin levels in blood and chronic widespread pain in patients with rheumatoid arthritis?
Conclusion
The study found that higher leptin levels are associated with an increased occurrence of chronic widespread pain in rheumatoid arthritis patients.
Supporting Evidence
- Patients with chronic widespread pain had significantly higher leptin levels compared to those without.
- The association between leptin levels and chronic widespread pain remained significant after adjusting for BMI, gender, and age.
- Higher leptin values were associated with higher odds ratios for chronic widespread pain.
Takeaway
This study shows that people with rheumatoid arthritis who have high levels of a hormone called leptin are more likely to have widespread pain.
Methodology
A cross-sectional study where 334 rheumatoid arthritis patients completed a questionnaire and provided blood samples to measure leptin levels.
Limitations
The study used existing blood samples that were not collected on the same day as the questionnaire, which may affect the accuracy of leptin level measurements.
Participant Demographics
Patients with rheumatoid arthritis, mean disease duration of 8 years, 71% female.
