  1. Validation of a self-administered lead exposure questionnaire among suburban teenagers.

    Article - En anglais

    Teenagers represent a unique population in which to evaluate lead exposure.

    A self-administered questionnaire was developed to evaluate the current and historic lead exposures of teenagers.

    This work evaluates the exposure questionnaire for both its ability to predict lead exposure and the accuracy of the teenage respondents.

    Subjects received the survey at school and were instructed to get assistance from their parents in questionnaire completion.

    Environmental samples (dust, soil, and water) were collected from 30 suburban Boston homes to evaluate the questionnaire's predictiveness.

    To evaluate the accuracy of subjects'responses, independent information about housing was obtained.

    The questionnaire was effective in identifying predictors of dust and soil lead levels, but not for water lead levels.

    Fine dust lead loading (<150 mum) varied significantly among the six housing age categories (pre-1940,1940-1949,1950-1959,1960-1969,1970-1979, and>1979) and traffic levels.

    Fine dust lead concentrations varied significantly with decade of housing construction.

    Mean soil lead levels varied significantly among housing age categories, traffic levels, and exterior construction materials.

    For the important predictors, there was excellent agreement between the teenagers'self-report and confirmatory information.

    For housing age categories, the observed agreement was 69% ; for traffic level, the observed agreement was 88%. (...)
