  1. Differential misclassification of alcohol and cigarette consumption by pregnancy outcome.

    Article - En anglais

    Background

    The validity of the results of studies using retrospectively collected information on exposures is often criticized, because cases may report differently from controls even if their true exposure status is the same.

    This study was performed to quantify the extent to which this effect (differential misclassification) may occur for alcohol and cigarette consumption by pregnancy outcome.

    Methods

    Prospective as well as retrospective information on alcohol and cigarette consumption was collected for 2806 mothers resident in all 12 provinces of the Netherlands, who gave birth between 1978 and 1979.

    Changes in mean reported consumption and changes from user to non-user based on retrospective and prospective information were compared for cases and controls.
