Each chapter covers the following essential points: incidence, prevalence, and cost of the problem, vital for gauging the importance of preventing the problem and for making the case for such efforts in public discussion of priorities; biological and environmental influences which increase or decrease the likelihood of these problems; and principles, programmes and policies that have been shown to reduce the incidence of each problem, information that can help in prevention of these behaviours.
