    Article - En anglais

    Fulltext.

    The authors used data from a population-based case-control study of breast cancer in women aged<44 years (cases, n=975 ; controls, n=866) conducted between 1994 and 1996 in three counties of western Washington state to assess the validity and reliability of reported perinatal factors.

    For a sample of participants, exposure information from self-administered questionnaires was validated with information from birth certificates (cases, n=378 ; controls, n=283).

    Detailed information regarding perinatal characteristics of their daughters was also collected from subjects'mothers (case mothers, n=510 ; control mothers, n=436) to assess the reliability of subjects'reporting of these events.

    Although reporting of birth weight by subjects (cases, r=0.83 ; controls, r=0.80) and their mothers (case mothers, r=0.89 ; control mothers, r=0.84) was highly correlated with the birth certificates, there was differential measurement error by subjects ; cases reported birth weight accurately on average, but controls tended to underestimate their birth weight.

    Agreement between the subject and mother report was excellent for birth weight (cases, r=0.85 ; controls, r=0.87) and good for other perinatal factors, but birth order and maternal diethylstilbestrol use were underreported among cases and reported accurately among controls.

    Differential measurement error of birth weight by case-control status resulted in biased odds ratios for breast cancer risk.
