Abstract

OBJECTIVES: To investigate associations between obesity, changes in body mass index (BMI), alcohol intake and smoking status and the development of Psoriatic Arthritis (PsA) in people with psoriasis.

METHODS: We have undertaken a cohort study involving incident psoriasis cases identified from the UK Clinical Practice Research Datalink between 1998 and 2014. The associations between smoking, alcohol and BMI and development of PsA were assessed using generalised additive models. Additionally, the risks associated with a change in BMI during follow-up were investigated using distributed lag non-linear models.

RESULTS: We identified 90,189 incident cases of psoriasis (42% males, mean age 51) of whom 1,409 had a subsequent record of PsA diagnosis. BMIs of 25.0-29.9, 30.0-34.9 and ≥35.0 were significantly associated with an increased risk of developing PsA compared to BMIs of <25.0: ORadj 1.79 (CI95 1.46 - 2.19), ORadj 2.10 (CI95 1.67 - 2.63), and ORadj 2.68 (CI95 2.09 - 3.43), respectively. Reducing BMI over a 10-year period (linearly) was associated with a reduction in the risk of developing PsA when compared to BMI remaining constant over the same period. Increased risks of developing PsA were associated with moderate drinking but not with ex- or heavy drinking or with current or past smoker status.

CONCLUSION: In this incident psoriasis cohort, increased BMI and moderate drinking but not heavy drinking or smoking status were associated with an increased risk of PsA in people with psoriasis. Importantly, we have shown that reducing weight may result in a reduction in the risk of developing PsA. This article is protected by copyright. All rights reserved.
