Minimal seasonal variation in disease parameters of axial spondyloarthritis: a register-based study.

ABSTRACT:

Objectives

Axial spondyloarthritis (axSpA) displays varying disease activity over time. However, few studies have examined the association between disease activity and seasonal differences, and consequently, evidence of a seasonality in disease activity in axSpA is limited. We therefore aimed to study the variation in measures of disease activity, perceived well-being, and functional ability, including both patient-reported and objective measures throughout the year, and their relationship with seasons.

Methods

Objective and patient-reported disease parameters from 44 987 assessments on 5197 individuals were retrieved from the Swedish Rheumatology Quality register. The variation in different measures of disease activity over the year was examined using generalized additive m
