There is increasing awareness that our health is closely linked to the natural and built environments in which we live. There is also strong evidence demonstrating the links between chronic disease and lifestyles characterised by car-dominated transport, reduced opportunities for exercise, increased fast food availability and lack of social connection.
Chronic diseases have overtaken infectious diseases as the leading causes of ill health in Australia. Obesity is rapidly becoming the major health burden for NSW with unprecedented levels of overweight and obesity across Australia. Overweight and obesity are major risk factors for chronic diseases including heart disease some cancers and type 2 diabetes.
The built environment has a key role to play in supporting human health as part of everyday living. The built environment comprises physical design patterns of land use, and the transport system; each influencing:
NSW Health has been developing its capacity to support built environments which contribute to our community’s health and well-being. NSW Health has a range of policies and tools to support the development of environments which reduce the impact of lifestyle related chronic diseases and promote population health and wellbeing.
The NSW Healthy Eating and Active Living Strategy
Building environments to support healthy eating and active living is a key component of the NSW Healthy Eating and Active Living Strategy: Preventing overweight and obesity in New South Wales 2013-2018. This is a coordinated cross-government strategy aimed at changing environments and supporting individuals to achieve and maintain a healthy weight throughout life.
Healthy Urban Living Development Checklist
The Healthy Urban Development Checklist is a tool which aims to assist health professionals to provide advice on, and participate in, urban development and land use planning.
The Checklist is to be used during the development phase of policies, plans and proposals, to assist with commenting on drafts, and to build relationships with planners and agencies involved in planning.
A range of risk factors and social determinants are addressed in the Checklist including, healthy food, physical activity, housing, transport, employment, safety and social cohesion and connectivity.
Some examples of how the Checklist has been used include:
In 2010 the Healthy Urban Development Checklist was included in the Planning Director-General's Requirements for Warnervale Town Centre, Woolworth's Retail Development on the NSW Central Coast.
In 2010 the Checklist was included in the Planning Director-General’s Requirements for the Airds Bradbury Urban Renewal Project and in 2011 it was included in the Planning Director-General’s Requirements for the Claymore Urban Renewal Concept Plan. Both projects are in South West Sydney.
Premier's Council for Active Living
The Premier's Council for Active Living (PCAL), funded by NSW Health, aims to build and strengthen the physical and social environments in which communities engage in active living.
PCAL has also developed a range of resources for developers on Designing Projects for Active Living. The NSW Developer’s Checklist is designed to assist developers who wish to include urban design factors that promote active living.
The built environment has an important role to play in reducing community exposure to environmental health hazards such as air, water and noise pollution as well as land contamination.
NSW Advocate for Children and Young People
The NSW Advocate for Children and Young People has also undertaken work to better understand and support the development of built environments that reflect the needs of children and young people.
Physical activity opportunities
Physical activity is an important factor in maintaining good health at any age. Regular moderate intensity physical activity – such as walking, cycling, or participating in sports – has significant benefits for health. For instance, it can reduce the risk of cardiovascular diseases, diabetes, colon and breast cancer, and depression.
The built environment can be designed to provide increased opportunities for physical activity through:
- active transport infrastructure to promote walking, cycling and public transport
- street connectivity, density, mixed use development
- public open space/green space
Healthy food access
Inadequate fruit and vegetable consumption is associated with coronary heart disease, some cancers, Type 2 diabetes, overweight and obesity, osteoporosis, dental caries, gall bladder disease, and diverticular disease.
The built environment can be shaped to support healthy eating options. Land use zoning and regulation can be used to influence:
- food retail environments
- accessible supermarkets and other fresh food outlets
- advertising, e.g. like billboards
- food production systems by:
- supporting farmers markets and community gardens
- protecting agricultural lands
Opportunities for social interaction and community connectivity
There are strong links between good health, a sense of community and social interaction. The built environment can foster a sense of community through enabling day to day interaction with people and nature in safe and accessible environments:
- people are less likely to interact within or feel part of a community that they perceive to be unsafe
- green and open spaces facilitate contact with nature as well as community.
