Abstract
Objective To examine the reproductive pattern of women with idiopathic inflammatory myopathy (IIM) compared to the general population.
Methods Population-based, nationwide registers were used to identify offspring of women with IIM and comparators.
Results Women with IIM in general had similar reproductive pattern as the comparators whereas those diagnosed between 26 and 45 years of age there was an overall trend for fewer children as well as trend for a higher proportion of nulliparity and a lower fertility rate in women with dermatomyositis than their comparators.
Conclusion Reproductive attention should be paid to patients with IIM diagnosed during childbearing period.
