Mørk S, Voss A, Möller S, et al. - A nationwide population of pregnant women was examined for the prevalence of spondyloarthritis (SpA) and subtypes diagnosed prior to delivery. In addition, researchers investigated how SpA was linked with adverse pregnancy‐related outcomes. The Danish Medical Birth Register yielded data of 1,199,610 singleton pregnancies (1997–2016). Prevalence of SpA prior to delivery was 0.31% overall, and it rose from 0.1% in 1997 to 0.6% in 2016. Adverse pregnancy outcomes more often complicated pregnancies in women with SpA than pregnancies in women without SpA. Based on findings, they emphasize clinicians to be aware of this when advising women with SpA in their childbearing years.
