Senior Research Fellow, National Heart Foundation Future Leader Fellow
BSc (1st Class Hons), PhD W.Aust.
Associate Professor Hayley Christian has more than 18 years’ professional experience in health promotion practice, health promotion research project management and health promotion teaching and research. To help people enjoy good health and wellbeing throughout their lives, Professor Christian’s research focuses on improving children’s physical activity, health and wellbeing through multi-level interventions that are focused on the child, the family, and social and built environments. This includes identifying strategies to create healthy early childhood education and care environments, and investigating how the home and neighbourhood environment shapes children’s health and development.
To make an impact on a wider scale, Professor Christian and her team work closely with government, non-government organisations, professional bodies and the private sector to identify and implement programs and policies to help children establish healthy behaviours early to provide the foundation for lifelong health.
Professor Christian is a Senior Research Fellow and National Heart Foundation Future Leader Fellow. She leads the PLAYCE (PLAY Spaces and Environments for Children’s Physical Activity, Health & Development) program of research, which is a multidisciplinary team focused on turning challenges into opportunities to make a positive difference in people’s health.

A study protocol for a randomised controlled trial to evaluate the effectiveness of a dog-facilitated physical activity minimal intervention on young children's physical activity, health and development: the PLAYCE PAWS trial
Pet ownership brings many health benefits to individuals. In children developmental benefits can extend to improved self-esteem, better social competence and decreased loneliness. The majority of households with children own a dog, however only a small proportion of children gain the benefits of dog ownership through dog walking and play. There are few intervention studies investigating the impact of dog-facilitated physical activity in children. The PLAYCE PAWS study aims to test a minimal-contact intervention through the use of mobile health ("mhealth") strategies, i.e. text (SMS) messages, to parents to encourage their children to walk and play with their dog more, and evaluate the impact on children's overall physical activity and development.
Published research Child Physical Activity, Health and DevelopmentMarch 2021Impact of covid-19 restrictions on western Australian children’s physical activity and screen time
Physical activity is essential for children’s healthy development, yet COVID-19 physical distancing restrictions such as school closures and staying at home, playground closures, and the cancelling of organised community sport have dramatically altered children’s opportunities to be physically active. This study describes changes in levels of physical activity and screen time from February 2020 (i.e., before COVID-19 restrictions were introduced in Western Australia) to May 2020 (i.e., when COVID-19 restrictions were in place). Parents of children aged 5 to 9 years from Western Australia were eligible to participate and recruited through convenience sampling.

A large proportion of preschoolers do not meet the recommended three hours of daily physical activity. A potential source of daily physical activity could be that provided via the family dog. This qualitative study aimed to explore the barriers and motivators to preschoolers playing with their dog and participating in family dog walks.
Published research Child Physical Activity, Health and DevelopmentApril 2021Exposomes and metabolic health through a physical activity lens: a narrative review
In this narrative review, we provide an overview of the role of physical activity as part of differing exposomes (our combined non-genetic exposures from conception onwards) and environmental influences on metabolic health. We discuss 'beneficial' exposomes (green/natural outdoor spaces, sun exposure, healthy diets and features of built environments) that could synergise with physical activity to prevent metabolic dysfunction, particularly that related to lifestyle diseases of obesity, type 2 diabetes and metabolic syndrome.

Social emotional development is imperative to young children's long-term psychological and physical health. Physical activity (PA) may be important for young children's social emotional development. The association between preschooler PA duration and intensity and social emotional development was investigated.

Emerging evidence supports the physical health and social benefits of dog ownership. This study examined the longitudinal effect of dog ownership and dog walking on mental health.
Published research Depression and Anxiety Child Physical Activity, Health and DevelopmentJuly 2021Gestational age and child development at school entry
Studies have reported a dose-dependent relationship between gestational age and poorer school readiness. The study objective was to quantify the risk of developmental vulnerability for children at school entry, associated with gestational age at birth and to understand the impact of sociodemographic and other modifiable risk factors on these relationships. Linkage of population-level birth registration, hospital, and perinatal datasets to the Australian Early Development Census (AEDC), enabled follow-up of a cohort of 64,810 singleton children, from birth to school entry in either 2009, 2012, or 2015.

Early childhood is a critical window for preventing obesity and chronic disease. Yet, 1 in 4 Australian children aged 5 years and under are affected by overweight or obesity; and significant proportions of children under 5 years fail to meet guidelines for diet quality, physical activity (PA), screen time, and sleep.

The environmental influences on early childhood development are understudied. The association between vegetation cover (i.e., trees, shrubs, grassed areas) in four key behaviour settings and socioemotional functioning was investigated in 1196 young children (2–5 years).

To advance active transport, robust policy-relevant evidence is needed to understand how to change behaviour and to support decision-making by policy makers and practitioners. Currently, however, priority research questions that are most critical for advancing active transport have not been identified.
