Changes

There's an increasing wealth of research and policy output on behaviour change in public health: a timely review of grey literature (material generated by government, or business, industry or academic communites but not published commercially) offers a useful survey. A paper from the US looks at ways to improve public health through interventions targeted at specific places (including schools, neighbourhoods, restaurants or recreational areas). Finally, a review of public health interventions delivered to whole communities assesses effectiveness, particularly in terms of impact on inequalities and also cost.
