SAMMENDRAG
Vanligvis måles eksponering for passiv røyking blant barn ved spørreskjemaopplysninger om
foreldres røykevaner. Etter hvert som det blir mer oppmerksomhet om helseeffekter av passiv
røyking, vil det kunne påvirke hvordan foreldre røyker og dermed også barns eksponering. Med
henvisning til innsamlede data om røykeeksponering i en kohort av Oslo-barn og fra en studie av
barn ved to helsestasjoner, diskuteres noen av de metodeproblemene en står overfor når en skal måle
eksponering for passiv røyking i epidemiologiske studier. I disse studiene er barns eksponering for
passiv røyking målt ved spørreskjemaopplysninger og ved måling av hårnikotin og kotinin i urin.
Det konkluderes med at det er usikkerhet om nøyaktigheten av eksisterende metoder for måling av
passiv røyking. Dette og manglende kunnskap om faktisk eksponeringsnivå kan føre til feilaktig
estimering av helseeffekter av passiv røyking i en barnebefolkning.

Problems in measuring environmental tobacco smoke exposure
in children.
Nor J Epidemiol 1995; 5 (2): 141-144.
ENGLISH SUMMARY
Usually environmental tobacco smoke exposure among children is measuered by questionnaires,
recording parental smoking. As the adverse health effects of environmental tobacco smoke exposure
are getting more known among the public, this is likely to influence the parents' way of smoking and
by that their children's actual exposure. With references to findings in a cohort study of Oslo
children and a study of children attending two of Oslo’s health centers, some methodological
problems when measuring environmental tobacco smoke exposure in epidemiological studies are
discussed. The exposure in these studies is measured in questionnaires to the parents and as
children's hair nicotine concentration and urine cotinine concentration. Furthermore, the paper
discusses how the uncertainty in actual levels of exposure may lead to false estimates for the total
health impact of environmental tobacco smoke exposure in a population of children.
