Authors' conclusion

Low SES is associated with increased risk of SjD compared to Sicca and with higher immunoglobulin levels. The Sicca cohort may be less deprived than the general population.

Study context

Population
Single-centre UK cohort of Sjögren's disease (SjD) and non-Sjögren's Sicca, with local population controls
Participants
256 / 175 / 972
Exposure
SjD vs non-Sjögren's Sicca vs population controls, by socioeconomic status (SES)
  • SjDn = 256
  • Siccan = 175reference
  • Population controlsn = 972
Outcome
Association of SES (IMD 2019 quintile and highest educational attainment) with SjD diagnosis vs Sicca and population controls
Methodological detailssingle-centre, adjusted logistic regression, population controls matched on age, sex and ethnicity
  • Single-centre
  • Adjusted logistic regression
  • Population controls matched on age, sex and ethnicity

Main finding

Odds of SjD vs Sicca by IMD quintile

Odds ratio

0.26

CI 0.12–0.58

P < 0.001

IMD quintile 2vs IMD quintile 1 (most deprived)
OR 0.26 (CI 0.12–0.58); P < 0.001

As reported in the abstract

SjD had lower SES than Sicca across Indices of Multiple Deprivation (IMD) and educational attainment
P = 0.008 and p=0.018

Observational data: associations, not effects.

Further findings

IgG and IgA levels in SjD per unit increase in IMD

IgG change per unit IMD increase
6.03% (−9.84%, −2.05%; p=0.003)
IgA change per unit IMD increase
6.46% (−10.87%, −1.60%; p=0.010)
  • Reduction

SES vs population controls

IMD not a risk factor for SjD
P = 0.257
Sicca associated with lower deprivation
P = 0.003
Degree level qualification had the highest odds of diagnosis (SjD or Sicca)
