The association of mobile phone use with health compromising behaviours (smoking, snuffing, alcohol)
was studied in a survey comprisinga representative sample of 14–16-year-olds (N ¼ 3485) in 2001. Mobile
phone was used by 89% of respondents and by 13% for at least 1 h daily. The intensity of use was positively
associated with health compromisingbehaviours. The associations remained, although somewhat reduced,
after includingweekly spendingmoney in the models. This study concludes that, at least in the present
developmental level of communication technologies, intensive mobile phone use seems to be part of the
same health-related lifestyle as health compromisingbehaviours.
