Smoking is associated with a worse self-reported health status in patients with psoriatic arthritis: data from a Swedish population-based cohort

• The aim was to study possible associations between smoking habits and self-reported clinical features in a large population-based cohort of patients with psoriatic arthritis (PsA). All subjects with PsA who had sought health care in the period 2003-2007 were identified using a regional health-care register. In 2009, all those identified who were 18 years of age or more (n = 2,003) were sent a questionnaire with questions on smoking, health-related quality of life [EuroQol five-dimension (EQ-5D)questionnaire], function [Health Assessment Questionnaire (HAQ)], pain, fatigue, and global health. We performed age- and sex-adjusted regression analysis to compare health status outcomes in never and ever smokers. Altogether, 1,185 subjects (59 %) returned the questionnaire. Mean age was 57 years (SD 13.5), and 58 % were women; 38 % were never smokers and 62 % were ever smokers. Mean age at disease onset was 38.2 years (SD 13.2) and 41.2 years (SD 13.6), respectively (p = 0.001). In age- and sex-adjusted data, ever smokers reported worse EQ-5D (p = 0.009); worse reports of global health (p = 0.01), pain (p = 0.01), and fatigue (p = 0.04); and a higher number of painful body regions (p = 0.04) compared to never smokers. In this population-based PsA cohort, patients who were ever smokers reported worse health status than never smokers. Besides being a possible result of a worse PsA in ever smokers, impaired health status could also be an effect of unstudied comorbidities. Further longitudinal studies are needed to gain a better understanding of cause and effect. However, smoking cessation should be recommended because of general health considerations as well as disease-specific issues.
