Background The incidence of inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease (CD), has exhibited a consistent rise in recent years across Asia and Taiwan. Existing literature suggests that women with IBD may experience suboptimal perinatal outcomes. However, the specific relationship between IBD in pregnant Taiwanese women and the subsequent health outcomes of their newborns remains unclear. This study aims to meticulously examine the association between maternal IBD and perinatal outcomes using extensive and representative health databases in Taiwan. Methods We utilized four large national representative health and welfare databases: 1) Maternal and Child Health Database, 2) Birth Certificate Database, 3) National Health Insurance Database, and 4) Catastrophic Illness Database. Data spanning from 2004 to 2018 were linked using encrypted personal IDs to establish a birth cohort during this period. Mothers identified with a registered IBD diagnosis (CD: ICD 9=555, ICD 10= K50.00-K50.919; UC: ICD 9=556.0-556.6 and 556.8-556.9, ICD 10= K51.00-K51.919) in the Catastrophic Illness Database were defined as cases, with a comparison group of healthy pregnant women matched 1:10 in the same birth year and maternal age. Statistical analyses were done by chi-square tests and conditional logistic regression models. Results Among the 3,059,647 births between 2004 and 2018, 146 newborns (126 UC; 20 CD) were born by mothers with a registered IBD diagnosis (Figure 1). No statistically significant differences were observed in stillbirth, preterm birth, cesarean delivery, low birth weight, small-for-gestational-age (SGA), large-for-gestational-age (LGA), and low Apgar scores when compared to the 1,460 matched healthy mothers (Table 1). The only significant difference was observed in the incidence of hypertensive disorders of pregnancy, with a lower prevalence in the IBD group compared to the control group (4.1% vs. 13.6%; p=0.001). Multivariate conditional logistic regression analysis disclosed no significant differences in the aforementioned perinatal outcomes. Subgroup analysis demonstrated that no difference was noted between the CD and UC groups. Conclusion Through this comprehensive analysis of long-term health and welfare databases in Taiwan, we found comparable perinatal outcomes between women with IBD and matched healthy women. The birth outcomes are also improved compared with previous studies. This may be associated with advancements in medical management for IBD in recent years. Further research is needed to explore the long-term neurodevelopmental outcomes of these newborns.
