Systemic sclerosis & Raynaud's

Determinants of Body Mass Index in Early Systemic Sclerosis: Implications for Nutritional Risk Stratification

Arthritis Care Res (Hoboken)Published Prospective cohort study

Authors' conclusion

Smaller oral aperture, intestinal pseudo-obstruction, and vascular severity were each independently associated with lower BMI.

Study context

Population
Patients with early systemic sclerosis (SSc) (2013 ACR/EULAR criteria, <5 years disease duration from first non-Raynaud symptom), prospective US cohortmean follow-up 5.3 years
Participants
450 patients
Outcome
Predictors of lower BMI (serial BMI measurements)
Methodological detailslinear mixed-effects models, univariable and multivariable analyses
  • Linear mixed-effects models
  • Univariable and multivariable analyses

Main finding

As reported in the abstract

Independent predictors of BMI, multivariable model adjusted for sex, race and follow-up time

Pseudo-obstruction (lower body mass index (BMI)): β

−6.28

P = 0.032

Smaller oral aperture (lower BMI): β

0.95

P = 0.049

Vascular severity (lower BMI): β

−0.85

P = 0.022

Observational data: associations, not effects.

Further findings

Predictors of BMI, univariable analyses

Younger age at baseline (lower BMI): β
0.06, P = 0.003
Anticentromere antibody positivity (higher BMI): β
1.69, P = 0.036
Pseudo-obstruction (lower BMI): β
−6.07, P = 0.026
Smaller oral aperture (lower BMI): β
1.03, P < 0.001
Higher Medsger vascular severity score (lower BMI): β
−2.11, P < 0.001
Higher Medsger cardiac severity score (lower BMI): β
−2.70, P = 0.049
