Abstract
To explore access to secondary mental health services for New Zealand women during pregnancy and for up to 1 year post-delivery. A retrospective cohort analysis of public hospital maternity data linked to mental health collections. 27 in 1000 pregnancies were associated with access to secondary mental health services (736/27,153). Independent of ethnicity, young age (< 20 years) was associated with access (RR1.84; 95 %CI 1.42-2.38; P < .0001). Smoking (1.48; 1.24-1.78; P < .0001), alcohol (1.3; 0.97-1.71; P < .0001) and substance use (3.57; 2.61-4.88; P < .0001) during pregnancy were independent risk factors associated with access. Antenatal period provides an opportunity for navigating to services to ensure timely access to secondary mental health services.
