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 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.
The NSW Ministry of Health is currently in the process of updating the Checklist, and a second edition is expected to be published in 2018.
The NSW Ministry of Health commissioned a review through The Australian Prevention Partnership Centre to estimate the health-related economic value of changes in urban form that impact on physical activity.
The Effects of Urban Form on Health: Costs and Benefits identified the associated average health-related benefit per adult annually of four built environment characteristics conducive to physical activity:
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.
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:
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:
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:
