Opioid use disorder: Calling pharmacists to action for better preconception and pregnancy care

Association between maternal mental health-related hospitalisation in the 5 years prior to or during pregnancy and adverse birth outcomes: a population-based retrospective cohort data linkage study in the Northern Territory of Australia

Background

Mental health conditions prior to or during pregnancy that are not addressed can have adverse consequences for pregnancy and birth outcomes. This study aimed to determine the extent to which women's mental health-related hospitalisation (MHrH) prior to or during pregnancy was associated with a risk of adverse birth outcomes.

Methods

We linked the perinatal data register for all births in the Northern Territory, Australia, from the year 1999 to 2017, to hospital admissions records to create a cohort of births to women aged 15-44 years with and without MHrH prior to or during pregnancy. We used Modified Poisson Regression and Latent Class Analysis to assess the association between maternal MHrH and adverse birth outcomes (i.e., stillbirth, preterm birth, low birth weight, and short birth length). We explored a mediation effect of covariates on theoretical causal paths. We calculated the adjusted Population Attributable Fraction (PAF) and Preventive Fractions for the Population (PFP) for valid associations.

Findings

From 72,518 births, 70,425 births (36.4% for Aboriginal women) were included in the analysis. The Latent Class Analys identified two classes: high (membership probability of 10.5%) and low adverse birth outcomes. Births to Aboriginal women with MHrH were around two times more likely to be in the class of high adverse birth outcomes. MHrH prior to or during pregnancy increased the risk of all adverse birth outcomes in both populations with risk ranging from 1.19 (95% CI: 1.05, 1.35) to 7.89 (1.17, 53.37). Eight or more antenatal care visits and intrauterine growth restriction mostly played a significant mediation role between maternal MHrH and adverse birth outcomes with mediation effects ranging from 1.04 (1.01, 1.08) to 1.39 (1.14, 1.69). MHrH had a low to high population impact with a PAF ranging from 16.1% (5.1%, 25.7%) to 87.3% (14.3%, 98.1%). Eight or above antenatal care visits avert extra adverse birth outcomes that range from 723 (332-765) stillbirths to 3003 (1972-4434) preterm births.

Interpretation

Maternal MHrH is a modifiable risk factor that explained a low to moderate risk of adverse birth outcomes in the Northern Territory. The knowledge highlights the need for the development and implementation of preconception mental health care into routine health services.

The effect of pregnant women's status of receiving preconception care on pregnancy stress

In the study, we aimed to determine the effect of pregnant women's status of receiving preconception care on their pregnancy stress. This is a descriptive, correlational, and cross-sectional design study, we were conducted with the participation of 409 pregnant women between June-December 2019. The Pregnancy Stress Rating Scale total score mean was found to be 30.72 ± 20.26. Individuals who received medication and vitamins as part of preconceptional care had significantly higher scores (p < 0.05; p < 0.001) compared to those who did not receive them for total pregnancy stress, postpartum social support, infant health, and infant identity-care stress. Similarly, individuals who received medical treatment and regular checkups had significantly higher scores (p < 0.05) compared to those who did not for total pregnancy stress, postpartum social support, infant identity-care, body image and psychological state during pregnancy stress scores. In addition, individuals who maintained a healthy lifestyle had significantly higher scores (p < 0.05; p < 0.001) compared to others for infant health, infant identity-care, and psychological distress during pregnancy. It was determined that women who made preparations for their pregnancy experienced more stress related to their babies (baby's health, baby's identity and care), psychological status in pregnancy, prenatal and postnatal social support, and body image.
