To examine whether responses to questions about the lifetime prevalence and 12-month period prevalence of symptoms of asthma and allergies are affected by the season in which the questions are asked.
The International Study of Asthma and Allergies in Childhood (ISAAC) Phase One was undertaken in six New Zealand centres ; in three centres the effect of season was studied.
Over three school terms at least 3000 children were studied in each of two age groups per centre (6-7 years ; 13-14 years), one-third in each term respectively.
The ISAAC standardized written questionnaires were used to identify asthma, rhinitis and eczema symptoms.
The written questionnaire in the younger age group was completed by the parent/guardian.
The older age group self-completed the written questionnaire and also a video questionnaire about asthma symptoms.
The total number of respondents was 21 437, approximately half in each age group.
The season of responding had no effect on the level of response to eczema questions.
For the written asthma questionnaire no season-of-response effect was present for 6-7 year olds ; for 13-14 year olds there was a trend to a higher rate of positive responses by those responding in winter, but in only one question did this reach statistical significance. (...)
