Questionnaires are more difficult to harmonize than biologicalor environmental sampling because of language and cultural specificities. They are however important tools to assess the routeof expositions. Methods: The first step of the work has been to gather questionnaires from all the birth cohorts on specificchosen exposures and to translate them into English. The second step will be to produce descriptive statistics from data of pilotor ongoing phases of the different cohorts. The third step will be to analyze the questions in relation to biological orenvironmental measurements in the different countries (not yet available) and to produce recommendations to select the morepertinent questions. Results: The first step highlighted the great diversity of questions provided by the experts from eachcountry and the absence of validated reference questionnaires at the national as well as at the international level. Descriptivestatistics for the assessment of domestic use of pesticides in the US, Japanese, and Chinese birth cohorts will be shown anddiscussed as an example. Conclusion: Environmental epidemiology is a recent field compared to other domains and there is aneed for standardization of questionnaires. The work of the Environment and Child Health International Birth Cohort Group is astep forward to allow selection of questions pertinent for a given exposure. Test retest reliability and back translation into<BR>different languages will also be an important issue to tackle.Quelle: Conference on Environment and Health Basel 201313 Vortragsfolienenghttp://rightsstatements.org/vocab/InC/1.0/Conference proceedings
