Prevalence of metabolic syndrome in patients with rheumatoid arthritis in eastern China—A hospital based study

Abstract

The purpose of this hospital clinic based study was to evaluate the potential risk factors associated with the prevalence of MetS in RA population. From January 2015 to October 2018, 717 patients with RA and 717 healthy controls who were treated or performed physical examination in Tianjin First Central Hospital were enrolled in this study. The basic disease diagnoses were recorded. A questionnaire was performed on all participants to assess the demographic details of the RA cohort. Moreover, laboratory indicators related to glucose and lipid metabolism in patients with RA were also detected. The potential risk factors for MetS were also analyzed. The prevalence of MetS were 31.2% and 34.2% in case and control groups, respectively (P=.22). There were lower levels of HDL-C, obesity, TG, LDL-C and TC in case group than control group (all P<.05). The hypertension levels in healthy controls was decreased in compared with patients with RA (P<.05). Nevertheless, in patients with RA, complement 3 (OR: 1.02; 95% CI: 1.01-1.03, P=.007) and less glucocorticoids use (OR: 0.63, 95% CI: 0.39-0.99, P=.046) were associated with MetS. The prevalence of MetS was not associated with RA. Complement 3 may be associated with the higher prevalence of MetS in patients with RA. Glucocorticoids treatment may be associated with MetS.
