Reproductive health in female patients with systemic sclerosis: a cross-sectional study

Abstract Objectives To explore the status of reproductive health and related factors in female patients with systemic sclerosis (SSc). Methods A cross-sectional study was conducted among female patients from the Chinese Organization for Scleroderma through a questionnaire. Data on the status of reproductive health including fertility condition and menstrual status were obtained. The clinical and laboratory data of SSc were collected. For patients with pregnancies after disease onset, each pregnancy was matched with a healthy control. Associations between clinical characteristics and the status of reproductive health were analysed. Results A total of 342 female patients with SSc were included, and 31.8% (108/342, 95% CI 26.9%–36.7%) of them presented problems with reproductive health. Compared with the national data, the menopausal age of patients with disease onset before menopause was earlier (45.2 ± 6.1 vs 48.2 ± 4.4, P < 0.001). Age of disease onset (P = 0.018) and digital ulcer (P = 0.020) had statistically significant effects on menopausal age. Although the infertility rate of patients was not increased, the rate of spontaneous abortions was higher compared with the national data (9/74, 12.2% vs 4.3%, P < 0.001). Compared with the healthy control group, the rate of premature infants (12/55, 21.8% vs 7/110, 6.4%, P = 0.003), low birth weight infants (15/55, 27.3% vs 6/110, 5.5%, P < 0.001), and cesarean section (27/55, 49.1% vs 21/110, 19.1%, P < 0.001) increased significantly. Conclusion The impairment of reproductive health is common and in many quarters in patients with SSc. Further action should be taken to improve reproductive health in patients with SSc, especially in maternal care.
