Objectives: The aims of this study were to describe patterns of pornography consumption, investigatedifferences between consumers and non-consumers of pornography regarding sexual experiences,health and lifestyle and determine associations between pornography consumption and sexualexperiences, health and lifestyle among adolescent girls. The hypotheses were that adolescent girlscategorised as pornography consumers would report sexual experiences to a greater extent, and ariskier lifestyle and poorer health, compared with non-consumers.Methods: A classroom survey was conducted among 16-year-old girls (N¼393).Results: One-third (30%) consumed pornography. In this group, almost half (43%) had fantasiesabout trying to copy sexual acts seen in pornography and 39% had tried to copy sexual activitiesseen in pornography. A higher proportion of pornography-consuming girls reported sexual experiencescompared with peers. A third (30%) reported experience of anal sex compared with 15%among non-consuming peers (p¼0.001). Furthermore, peer-relationship problems (17% vs 9%;p¼0.015), use of alcohol (85% vs 69%; p¼0.001) and daily smoking (27% vs 14%; p¼0.002) werereported to a greater extent than in non-consuming peers. Pornography consumption, use of alcoholand daily smoking were associated with experience of casual sex.Conclusions: Pornography-consuming girls reported sexual experiences and a risky lifestyle to agreater extent compared with non-consuming girls. This indicates that pornography consumptionmay influence sexualisation and lifestyle. This is important to acknowledge when designing andimplementing sexual health programmes for adolescents.
