A study by Graff et al. found differences in attitudes to the internet with lower age group (17-19)reporting more positive attitudes than older age groups(21-32). Again, this highlights the need to consider the target group in detail, rather than making estimations that everyone adult age range behaves identically. Age can also correlate with knowledge and Marek et al. note that older age correlate with better knowledge of sexually transmitted infections Age can influence reaction to message content. For example, Henley and Donovan illustrate that scare in the media have little effect on older females, who respond significantly more to non-threats, whereas older males were seen to respond more to scare tactics. Other research suggests age-related complexities. For example in a drug use campaign different age groups reported different drug use levels with campaign awareness. The wording of health promotion message will also need consideration. How a health product is labeled or packaged has an impact on different audiences. Latimer et al. note that adolescent smokers find generic warning labels on cigarette packets uninteresting and irrelevant, and only pay attention or think about these labels some of the time suggesting other preventive strategies may need to be considered for younger smokers
