Randomized Controlled Trial
Social network targeting to maximise population behaviour change: a cluster randomised controlled trial.
Information and behaviour can spread through interpersonal ties. By targeting influential individuals, health interventions that harness the distributive properties of social networks could be made more effective and efficient than those that do not. Our aim was to assess which targeting methods produce the greatest cascades or spillover effects and hence maximise population-level behaviour change. ⋯ National Institutes of Health, The Bill & Melinda Gates Foundation, Star Family Foundation, and the Canadian Institutes of Health Research.

Our aim was to forecast mortality and life expectancy for England and Wales' districts. ⋯ UK Medical Research Council and Public Health England.
