https://www.linkedin.com/in/mary-brushe-413749102/Dr Brushe is a Senior Research Officer in Epidemiology at The Kids Research Institute Australia and an Adjunct Research Fellow at The University of Adelaide and the University of Western Australia. Mary completed her PhD (Public Health) in 2024, which explored early life inequalities in language development and screen time, using longitudinal cohort data and was awarded the PhD Research Excellence Category at the 2024 South Australian Science and Innovation Awards. Her expertise focuses on early childhood health and development, early language experiences, screen time in early childhood, mental health and well-being, social determinants of health and epidemiological research methods. Since completing her PhD, Mary has been working within the Indigenous Genomics team at The Kids, a multidisciplinary team aimed at addressing health inequities for Aboriginal and Torres Strait Islander communities.
Dr Brushe’s research has been featured in over 800 media outlets internationally and her paper on screen time and early language was the number one downloaded peer-reviewed journal article in JAMA Pediatrics for 2024. She led the development of a new intervention, Early Start Screen Smart, aimed at helping parents of very young children create healthy screen time habits in their families taking an evidence-based, non-judgemental approach to screen time. Furthermore, she has expertise in social epidemiology, longitudinal data analysis, participant recruitment and data collection, co-design methodologies, and public health advocacy, with a passion for ensuring her research is community driven and drives policy and practice change.
Mary is also the current President of the Public Health Association of Australia (SA Branch), amember of the 0-3 Early Years Taskforce in South Australia, and the Co-Chair of the Student and Postdoc Committee for the International Social Epidemiology Society. She is always interested in forming new collaborations with passionate researchers, policymakers or practitioners working in public health and epidemiology.

Breakfast skipping among children and adolescents in South Australia
Eating a regular, healthy breakfast is required to support good health, wellbeing and development throughout childhood and adolescence.
Child development at school entry and student wellbeing six years later
It has been well established that children's development at school entry is associated with their later academic achievement, but less is known about whether there is also an association with other measures of school success, such as students' social and emotional wellbeing.
National School Readiness Project
Researchers at the Institute were engaged to undertake the National School Readiness Project, which aimed to describe current practice across education authorities in assessing or describing child development status at school entry and use evidence to identify areas where the scope/quality of curren

Language in Little Ones (LiLO)
The Language in Little Ones (LiLO) study is a five-year longitudinal study (2017-2021), funded through the National Health and Medical Research Council. The study investigates the quantity and quality of language exposure in the home environment during the first five years of a child’s life.

Associations between mental health profiles and later school outcomes
The dual-factor model of mental health proposes that high wellbeing and low distress are necessary to define mental health. This study used latent profile analysis to identify mental health profiles in a sample of 3,587 Australian grade 6 students and explored the association between mental health profiles and school outcomes measured in grades 7 and 9.
Screen Time and Parent-Child Talk When Children Are Aged 12 to 36 Months
Growing up in a language-rich home environment is important for children's language development in the early years. The concept of "technoference" (technology-based interference) suggests that screen time may be interfering with opportunities for talk and interactions between parent and child; however, limited longitudinal evidence exists exploring this association.
Mental health profiles and academic achievement in Australian school students
This study explored mental health profiles in Australian school students using indicators of well-being (i.e., optimism, life satisfaction, and happiness) and psychological distress (i.e., sadness and worries). The sample included 75,757 students (ages 8-18 years) who completed the 2019 South Australian Wellbeing and Engagement Collection.
The Investigation of Health-Related Topics on TikTok: A Descriptive Study Protocol
The social media application TikTok allows users to view and upload short-form videos. Recent evidence suggests it has significant potential for both industry and health promoters to influence public health behaviours. This protocol describes a standardised, replicable process for investigations that can be tailored to various areas of research interest, allowing comparison of content and features across public health topics.
Objectively measured infant and toddler screen time: Findings from a prospective study
Screen time guidelines recommend no screens under two years due to the potential negative impacts on development. While current reports suggest many children exceed this, research relies on parent reports of their children's screen exposure. We objectively assess screen exposure during the first two years and how it differs by maternal education and gender.
Implementing a combined individual placement and support and vocational peer work program in integrated youth mental health settings
To describe the implementation and outcomes of a combined individual placement and support (IPS) and vocational peer work program for young people with mental ill-health.
Prevalence of breakfast skipping among children and adolescents: a cross-sectional population level study
Interventions to promote breakfast consumption are a popular strategy to address early life inequalities. It is important to understand the epidemiology of children and adolescents who skip breakfast so that interventions and policy can be appropriately considered.
Prevalence of electronic device use before bed among Australian children and adolescents: a cross-sectional population level study
To understand the prevalence of children and adolescents’ electronic device use (EDU) in the hour before bed and identify sociodemographic groups that are at increased risk of problematic use.
Shared Decision Making With Young People at Ultra High Risk of Psychotic Disorder
While the majority of young people who meet the criteria for being considered at increased risk of psychosis do not go on to develop a psychotic disorder, young people are currently being identified and treated in early intervention services.
Basic epidemiology of wellbeing among children and adolescents: A cross-sectional population level study
Wellbeing and mental health are fundamental rights of children and adolescents essential for sustainable development. Understanding the epidemiology of child and adolescent wellbeing is essential to informing population health approaches to improving wellbeing and preventing mental illness.
The education word gap emerges by 18 months: findings from an Australian prospective study
The idea of the '30 million word gap' suggests families from more socioeconomically advantaged backgrounds engage in more verbal interactions with their child than disadvantaged families. Initial findings from the Language in Little Ones (LiLO) study up to 12 months showed no word gap between maternal education groups.
Inside the black box of youth participation and engagement: Development and implementation of an organization-wide strategy for Orygen, a national youth mental health organization in Australia
The involvement of young people in the development, implementation and evaluation of youth mental health services, policy and research programs is essential to ensure they are appropriate and responsive to the needs of young people. Despite the increasingly central role that youth engagement and participation plays internationally, such activities are rarely described in detail.
Associations between School Readiness and Student Wellbeing: A Six-Year Follow Up Study
It is well established that children’s school readiness is associated with their later academic achievement, but less is known about whether school readiness is also associated with other measures of school success, such as students’ social and emotional wellbeing. While some previous research has shown a link between early social and emotional development and student wellbeing, results are mixed and the strength of these relationships vary depending on whether data is based on child, teachers or parents ratings and which specific student wellbeing outcomes are measured.
How many words are Australian children hearing in the first year of life?
These results show that a word gap related to maternal education is not apparent up to twelve months of age
