“…A review of interventions on encouraging walking and cycling concluded that 4 of the 69 included publications came from "first line health databases", compared to 8 from social science sources and 33 from a topic-specific transport database (Ogilvie, Hamilton, Egan, & Petticrew, 2005). Further evidence on the value of searching beyond MEDLINE is available on a number of topics relevant to public health, including: occupational health (Rollin, Darmoni, Caillard, & Gehanno, 2010), social welfare (Taylor, Wylie, Dempster, & Donnelly, 2007), maternal health (Betran, Say, Gulmezoglu, Allen, & Hampson, 2005), mental health (Lohonen, Isohanni, Nieminen, & Miettunen, 2010), mental illness (Brettle & Long, 2001), psychiatry (Mcdonald, Taylor, & Adams, 1999), and injury prevention (Lawrence, 2008).…”
