The association between objectively measured exposure to tobacco outlets and smoking cognitions: a study among non-smoking adolescents in four Dutch cities.

Aims: Exposure to tobacco products and advertising at the point of sale may be associated with pro-smoking cognitions. However, previous studies on this topic measured exposure based on self-report and did not include European countries. The aim of this study was to assess the association between objectively measured exposure to tobacco outlets and non-smoking adolescents' smoking attitudes, beliefs and norms.
