Abstract
OBJECTIVE: Women with systemic lupus erythematosus (SLE) may experience adverse perinatal outcomes in the years before an SLE diagnosis. Overall, there is limited research on perinatal outcomes among African American women with SLE. We undertook this study to examine the risk of preterm and small-for-gestational age births among African American women with SLE compared to the general population of African American women in a large metropolitan area. METHODS: Information about women with SLE was identified from the Georgia Lupus Registry and the Georgians Organized Against Lupus Cohort and was linked with birth certificates by the Georgia Department of Public Health. Births were categorized into occurring more than 3 years before SLE diagnosis, 0-3 years before SLE diagnosis, 0-3 years after SLE diagnosis, or more than 3 years after SLE diagnosis. Comparison birth certificates to African American women in the same geographic area were obtained from the National Center for Health Statistics. We used log-risk models to compare the risk of preterm or small-for-gestational age births among SLE births in each diagnosis timing category to the general population, adjusting for maternal age and education and parity. RESULTS: Births to women with SLE were more likely to occur preterm at 0-3 years before SLE diagnosis (risk ratio [RR] 1.71, 95% confidence interval [95% CI] 1.24-2.35), 0-3 years after SLE diagnosis (RR 2.29, 95% CI 1.70-3.09), and 3 or more years after SLE diagnosis (RR 2.83, 95% CI 2.36-3.38), but not 3 or more years before SLE diagnosis compared to the general population (RR 1.03, 95% CI 0.77-1.38). Similar results were observed for small-for-gestational age births. CONCLUSION: Our analysis, conducted among African American women, demonstrates an increased risk of adverse perinatal outcomes even before a clinical diagnosis of SLE.
