Attitudes Beliefs & Philosophy…on the topic of evidence Fewer DBRCTs et al More case study, observational, market research Behaviour measures linked to intervention and outcome
Health economics puts the story in a language decision-makers respond to
Policy analysis brings it all together to tell the story of what is happening, why, and with what consequences

The ADGsAvailable scientific evidence of what to eat to achieve good
health.

The Problem
Australia is ranked in the world’s ‘worst third’ for obesity
Almost in the world’s ‘worst third’ for fruit & veg intake
Australians are not choosing the food science instructs them to
ADGs

It is a problem because… An unwell population is less productive Pain and suffering (QOL) Resource use
One in two Australian adults are BMI>25kg/m2
Treatment is prevention

Obesity clusters in households
72% of households are a ‘family’
2.5 million Australians making food choices everydayon behalf of others
Cost is an issue
$8pp/d = 40% of total weekly income for welfare dependent family

The difference with ‘food’ as the problem Every person eats Individual is ‘gatekeeper’ Making choices daily, every day Choice based on individual attitudes, beliefs, behaviours Everyone’s an expert (or can be)

Cost relative to income is an issue
Kettings CM Voevodin M Sinclair AJ. A healthy diet consistent with Australian health recommendations is too expensive for welfare-dependent families. Australian and New Zealand Journal of Public Health 2009 33(6): 566-572
The cost of healthy food habits uses about 40% of the disposable income of welfare-dependent families. Families earning an average income would spend 20% for the same food.
Healthy food habits are a fiscal challenge to welfare-dependent families.

What are the ADGs asking us to do? No alcohol or non-alcoholic drinks
Eat three meals a day, most at home
Ignore the price drops and other strategies used to promote and market unhealthy food
Allow time to shop, transport, store, prepare, cook, serve, eat home-prepared meals, and clean-up
Have resources (money) for kitchen, storage, transport, cooking, dining, and cleaning-up infrastructure

Key Points Australians do not meet the ADGs
There is a gap between prescribed behaviour and actual behaviour
Cost is important, but may not be the most influential
Investigating actual behaviour is an important next step for policy
![Page 31: Is there life outside the Australian Dietary Guidelines?](https://reader034.fdocuments.net/reader034/viewer/2022042907/587809d81a28ab971e8b570f/html5/thumbnails/31.jpg)
Key Points Factors influencing behaviour:1. Food preferences2. Marketing strategies3. Time commitment4. Resources required5. Cost of healthy food
![Page 32: Is there life outside the Australian Dietary Guidelines?](https://reader034.fdocuments.net/reader034/viewer/2022042907/587809d81a28ab971e8b570f/html5/thumbnails/32.jpg)

What does this all mean for policy & practice?
Issue Consider..
Obesity is bad Business as usual is not an option
ADGs hard DBRCTs might not be best approach
Food choices Understanding behaviour (real life v prescribed)
Treatment Priority given to primary carer for servicesAnd women of childbearing age
![Page 33: Is there life outside the Australian Dietary Guidelines?](https://reader034.fdocuments.net/reader034/viewer/2022042907/587809d81a28ab971e8b570f/html5/thumbnails/33.jpg)
Key Points
Effective health policy requires an understanding of how each of the behavioural factors influence food
selection, and how these change with economic status.

A starting point for total cost
Preference
Willingness to spend on healthy food compared with unhealthy; Taste, familiarity, texture, risk, satisfaction and effect on willingness to spend
Marketing Frequency and type; effect of price elasticity on demand; relative to unhealthy foods
Time To cook, shop, prepare, clean up, transport; effort (relative to income); opportunity cost
Resources To cook, shop, prepare, clean up, transport; effort (relative to income); opportunity cost
Cost Actual cost; inflation; relative to income; relative to unhealthy food; relative to actual spend
