Models of science-policy relationship

There are increase in diet-related ill-health in the community with increase in non-communicable diseases due to the industrial food, salty and fatty food.

One of the illustrations will be obesity. Energy gap models which quantified the association of changes in energy intake and expenditure with weight change, and have documented the effect of higher intake on obesity prevalence.

Policies:

- involve many parties (such as governments, international organisations, the private sector, and civil society) need to contribute

- policies to improve food and build environments

- cross-cutting actions (such as leadership, healthy public policies, and monitoring)

- greater funding for prevention programmes

- actions within existing systems into both health and non-health sectors (trade, agriculture, transport, urban planning, and development)

Science:

- use quantitative models (insights into the dynamics of their epidemic, and enabled researchers to combine evidence and to calculate the effect of behaviours, interventions, and policies at several levels - from individual to population)
