Patients with PsA when compared with controls had higher BMI (27.2 vs 25.9 kg/m2, P < .001) and lower high-density lipoprotein cholesterol (HDL-C) (1.32 vs 1.40 mmol/L, P < .03), and more of those with PsA were smokers (41.1% vs 28.5%, P < .01).
Patients with PsA gained less weight than the control group (2.1 vs 3.9 kg), with a significant difference in mean change of −1.8 kg (95% confidence interval [CI]: −3.9 to −0.5, P < .01).
Those with PsA had a greater reduction in total cholesterol values than the controls, with a difference in mean change between the groups of −0.22 mmol/L (P = .04).
More patients with PsA started smoking during the decade-long study compared with controls (8.5% vs 3.1%, P = .03).
