TOPLINE:
MRI-derived abdominal adipose tissue is linked to chronic musculoskeletal pain in multiple sites. The association is stronger in women, suggesting sex differences in fat distribution and hormones.
METHODOLOGY:
- Researchers used data from the UK Biobank, a large population-based cohort study, to investigate the associations between MRI-measured abdominal adipose tissue and chronic musculoskeletal pain.
- A total of 32,409 participants (50.8% women; mean age, 55.0 ± 7.4 years) were included in the analysis, with abdominal MRI scans performed at two imaging visits.
- Pain in the neck/shoulder, back, hip, knee, or “all over the body” was assessed, and participants were categorized based on the number of chronic pain sites.
- Mixed-effects ordinal, multinomial, and logistic regression models were used to analyze the associations between visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), and their ratio with chronic pain.
TAKEAWAY:
- According to the authors, there was a dose-response association between VAT, SAT, and their ratio with the number of chronic pain sites in both women and men.
- Higher levels of abdominal adipose tissue were associated with greater odds of reporting chronic pain in both sexes, with effect estimates being relatively larger in women.
- The researchers found that the VAT/SAT ratio was associated with the number of chronic pain sites and chronic pain in both sexes, reflecting differences in fat distribution and hormones.
- The study suggested that excessive abdominal adipose tissue may be involved in the pathogenesis of multisite and widespread chronic musculoskeletal pain.
IN PRACTICE:
“Abdominal adipose tissue was associated with chronic musculoskeletal pain, suggesting that excessive and ectopic fat depositions may be involved in the pathogenesis of multisite and widespread chronic musculoskeletal pain,” wrote the authors of the study.
SOURCE:
This study was led by Zemene Demelash Kifle, University of Tasmania Menzies Institute for Medical Research in Hobart, Australia. It was published online in Regional Anesthesia & Pain Medicine.
LIMITATIONS:
The study’s limitations included the use of a pain questionnaire that did not assess pain severity, which limited the ability to examine the relationship between fat measures and pain severity. Additionally, MRI was conducted on only two occasions, which may have not captured patterns and fluctuations in chronic pain sites. The relatively small size of the imaging sample, compared with the original baseline sample limited the generalizability of the findings. The predominant White ethnicity of participants also limited the generalizability to diverse populations.
DISCLOSURES:
The study was supported by grants from the Australian National Health and Medical Research Council (NHMRC). Mr. Kifle disclosed receiving grants from the Australian NHMRC. Additional disclosures are noted in the original article.
