Influences on drinking choices among Indigenous and non-Indigenous pregnant women in Australia: A qualitative study

A data driven approach to identify trajectories of prenatal alcohol consumption in an Australian population-based cohort of pregnant women

Accurate information on dose, frequency and timing of maternal alcohol consumption is critically important when investigating fetal risks from prenatal alcohol exposure. Identification of distinct alcohol use behaviours can also assist in developing directed public health messages about possible adverse child outcomes, including Fetal Alcohol Spectrum Disorder. We aimed to determine group-based trajectories of time-specific, unit-level, alcohol consumption using data from 1458 pregnant women in the Asking Questions about Alcohol in Pregnancy (AQUA) longitudinal study in Melbourne, Australia. Six alcohol consumption trajectories were identified incorporating four timepoints across gestation. Labels were assigned based on consumption in trimester one and whether alcohol use was continued throughout pregnancy: abstained (33.8%); low discontinued (trimester one) (14.4%); moderate discontinued (11.7%); low sustained (13.0%); moderate sustained (23.5%); and high sustained (3.6%). Median weekly consumption in trimester one ranged from 3 g (low discontinued) to 184 g of absolute alcohol (high sustained). Alcohol use after pregnancy recognition decreased dramatically for all sustained drinking trajectories, indicating some awareness of risk to the unborn child. Further, specific maternal characteristics were associated with different trajectories, which may inform targeted health promotion aimed at reducing alcohol use in pregnancy.

Responding to the Unique Complexities of Fetal Alcohol Spectrum Disorder

Fetal alcohol spectrum disorder (FASD) is a multifaceted disability, characterized not only by brain- and body-based challenges, but also high rates of environmental adversity, lifelong difficulties with daily living, and distinct sociocultural considerations. FASD is one of the most common neurodevelopmental disabilities in the Western world and associated with significant social and economic costs. It is important to understand the complexities of FASD and the ways in which FASD requires unique consideration in research, practice, and policy. In this article, we discuss our perspectives on factors that distinguish FASD from other disabilities in terms of complexity, co-occurrence, and magnitude. We provide an overview of select literature related to FASD as a socially rooted disability with intergenerational impacts and multiple layers of stigma. These social issues are intertwined with notable experiences of adversity across the lifespan and high rates of co-occurring health concerns for individuals with FASD, all of which present unique challenges for individuals, caregivers, families, service providers, and policy makers. Understanding these factors is the first step in developing and implementing specialized initiatives in support of positive outcomes for individuals with FASD and their families. Future directions are proposed for advancing research, practice, and policy, and responding to the unique complexities of FASD.

Cohort profile: early school years follow-up of the Asking Questions about Alcohol in Pregnancy Longitudinal Study in Melbourne, Australia (AQUA at 6)

PURPOSE

The Asking Questions about Alcohol in Pregnancy (AQUA) study, established in 2011, is a prebirth cohort of 1570 mother and child pairs designed to assess the effects of low to moderate prenatal alcohol exposure and sporadic binge drinking on long-term child development. Women attending general antenatal clinics in public hospitals in Melbourne, Australia, were recruited in their first trimester, followed up three times during pregnancy and at 12 and 24 months postpartum. The current follow-up of the 6-8-year-old children aims to strengthen our understanding of the relationship between these levels of prenatal alcohol exposure and neuropsychological functioning, facial dysmorphology, brain structure and function.

PARTICIPANTS

Between June 2018 and April 2021, 802 of the 1342 eligible AQUA study families completed a parent-report questionnaire (60%). Restrictions associated with COVID-19 pandemic disrupted recruitment, but early school-age neuropsychological assessments were undertaken with 696 children (52%), and 482 (36%) craniofacial images were collected. A preplanned, exposure-representative subset of 146 children completed a brain MRI. An existing biobank was extended through collection of 427 (32%) child buccal swabs.

FINDINGS TO DATE

Over half (59%) of mothers consumed some alcohol during pregnancy, with one in five reporting at least one binge-drinking episode prior to pregnancy recognition. Children's craniofacial shape was examined at 12 months of age, and low to moderate prenatal alcohol exposure was associated with subtle midface changes. At 2 years of age, formal developmental assessments showed no evidence that cognitive, language or motor outcome was associated with any of exposure level.

FUTURE PLANS

We will investigate the relationship between prenatal alcohol exposure and specific aspects of neurodevelopment at 6-8 years, including craniofacial shape, brain structure and function. The contribution of genetics and epigenetics to individual variation in outcomes will be examined in conjunction with national and international collaborations.

Vision, future, cycle and effect: A community life course approach to prevent prenatal alcohol exposure in central Australia

Issue addressed

Prevention approaches specific to prenatal alcohol exposure (PAE) and foetal alcohol spectrum disorder (FASD) have been identified as urgently needed in Australia, including in Aboriginal and Torres Strait Islander communities. However, very little work has aimed to describe and evaluate health promotion initiatives, especially those developed in rural and remote areas.

Methods

A series of television commercial scripts (scripts) were developed with health promotion staff at an aboriginal and Torres Strait Islander Community Controlled Health Service and piloted with 35 community members across six yarning sessions.

Results

Scripts evoked responses in line with two predominant themes: “Strength” and “Community resonance.” This process led to the development of a four‐part television and radio campaign focusing on a life course approach to prevent prenatal alcohol exposure (PAE) – “Vision,” “Future,” “Cycle” and “Effect.”

Conclusions

Intergenerational influences on PAE were key elements of scripts positively received by community members. Strengths of this work included a flexible approach to development, local aboriginal men and women coordinating the yarning sessions, and the use of local actors and familiar settings.

So what?

Preventing PAE is extraordinarily complex. Initiatives that are culturally responsive and focus on collective responsibility and community action may be crucial to shifting prominent alcohol norms. Future work is necessary to determine the impact of this campaign.

"The Problem Is that We Hear a Bit of Everything…": A Qualitative Systematic Review of Factors Associated with Alcohol Use, Reduction, and Abstinence in Pregnancy

Understanding the factors that contribute to women's alcohol use in pregnancy is critical to supporting women's health and wellness and preventing Fetal Alcohol Spectrum Disorder. A systematic review of qualitative studies involving pregnant and recently postpartum women was undertaken to understand the barriers and facilitators that influence alcohol use in pregnancy (PROSPERO: CRD42018098831). Twenty-seven (n = 27) articles were identified through EMBASE, CINAHL, PsycINFO, PubMed and Web of Science. The included articles were thematically analyzed using NVivo12. The analysis was informed by Canada's Action Framework for Building an Inclusive Health System to articulate the ways in which stigma and related barriers are enacted at the individual, interpersonal, institutional and population levels. Five themes impacting women's alcohol use, abstention and reduction were identified: (1) social relationships and norms; (2) stigma; (3) trauma and other stressors; (4) alcohol information and messaging; and (5) access to trusted equitable care and essential resources. The impact of structural and systemic factors on prenatal alcohol use was largely absent in the included studies, instead focusing on individual choice. This silence risks perpetuating stigma and highlights the criticality of addressing intersecting structural and systemic factors in supporting maternal and fetal health.
