We generated adjusted relative risks (aRR) and 95% confidence intervals (CI), adjusted for maternal age, parity, infant sex, immigration status, income, rurality, non-ADHD preconception mental illness, and year of delivery.<\/p>\n<p><strong>Results<\/strong> \u2014 Among those with ADHD (n\u2009=\u200922,995), 50.2% were diagnosed with perinatal mental illness whereas among those without ADHD (n\u2009=\u20091,028,038), only 24.0% were diagnosed, an aRR of 1.35 (95%CI 1.33\u20131.38). ADHD was associated with elevated risk for anxiety (41.7% vs. 20.7%; aRR 1.34, 1.31\u20131.37), depressive (14.4% vs. 5.0%; aRR 1.65, 1.59\u20131.71), substance and alcohol use (6.3% vs. 1.4%; aRR 1.71, 1.61\u20131.80); bipolar (4.4% vs. 1.0%; aRR 2.29, 2.14\u20132.45) and psychotic disorders (1.2% vs. 0.3%; aRR 2.37, 2.10\u20132.68), as well as with psychiatric ED visits (8.2% vs. 1.6%; aRR 1.98, 1.88\u20132.08) and psychiatric hospitalizations (2.4% vs. 0.4%; aRR 2.26, 2.06\u20132.48).<\/p>\n<p><strong>Conclusions<\/strong> \u2014 Perinatal mental illness and the need for acute perinatal mental health care are elevated among those with ADHD, highlighting the need for targeted supports and services to enhance prevention and early identification in this group.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Purpose \u2014 Attention deficit hyperactivity disorder (ADHD) affects\u2009~\u20092% of reproductive-aged women, yet the impact of ADHD on perinatal psychiatric outcomes remains poorly understood.
