Data on substance use/dependence, mental health and from the sexual health theme led by Nigel Dickson (e.g. [98–104]); also see [105, 106]) have been used in a variety of New Zealand policy-making contexts (e.g. Health Select Committee reports, Law Commission reports, and a variety of professional bodies, e.g. the NZ Herpes Foundation), as well as overseas (e.g. WHO, UK House of Lords, the U.S. Presidential Office, US Surgeon-General’s reports). One recent example of impact in the U.S. context relates to a series of reports produced by the Center on the Developing Child at Harvard University and the American Academy of Pediatrics about the ‘new science’ of child development in which research from the Dunedin Study features [107, 108].
