Aim: Australian adolescents are increasingly using mobile telephones (MP) while the debate on MP safety persists. This group is not generally engaged in full‐time employment, suggesting that their MP use is not work related. We investigated possible predictors of MP use in young people. Methods: We assessed exposure to radiofrequency energy from MP by means of a self‐administered questionnaire adapted from INTERPHONE – an international case‐control study of adult brain, head and neck tumours. We investigated possible determinants of MP use in adolescent Australians using self‐reported number of incoming and outgoing voice calls as exposure metric. Results: There is a high prevalence of MP use amongst Australian adolescents (94%). Males were significantly younger than females at age of first uptake of MP ( P = 0.02). Participants without siblings were significantly younger at age of first uptake. Personality traits were associated with regular MP usage: higher psychoticism scores were associated with regular use (IRR = 1.06, P = 0.03); there was a tendency for students with higher extraversion scores to report more MP use. Parental socio‐economic status was associated with MP use, but parents who expressed moderate/high level concerns about possible health risks of use were more likely to have children who used MP (OR = 4.06, P = 0.05). Conclusions: Almost all adolescent Australians use MP, but regular exposure was associated with personality traits. Parental socio‐economic status and perceived health risks of MP use were also associated with use of phones. Longitudinal studies are needed to assess the predictors of mobile phone use in the long term.
