The aim of the study was to assess the ability of the European Communi
ty Respiratory Health Survey (ECRHS) questionnaire to provide data on
the prevalence, type and reported symptoms associated with food intole
rance from a group of young adults in Melbourne. Six hundred and sixty
nine randomly selected subjects completed the questionnaire with 553
attending the laboratory for skin-prick tests, anthropometry, and vent
ilatory function tests, A further 207 symptomatic participants complet
ed the questionnaire, with 204 of them attending the laboratory. Seven
teen per cent of all respondents reported food intolerance or food all
ergy. A wide variety of food items was cited as being responsible for
food-related illnesses, Those with current asthma did not report food-
related illness more frequently than those without asthma. Respondents
who reported respiratory symptoms following food ingestion were more
likely to be atopic, to have used inhaled respiratory medications in t
he previous 12 months, reported less exposure to regular passive smoki
ng over the past 12 months and weighed more. These associations betwee
n respiratory symptoms and food intolerance require further prospectiv
e investigation and verification. The importance of using appropriate
dietary methodology in future studies for determining diet-disease rel
ationships was highlighted by this study.
