Abstract
Women exposed to preeclampsia during fetal life have lower risk of breast cancer, compared with unexposed women, possibly through fetal programming. Hypothetically, preeclampsia exposure could affect well-known risk factors for breast cancer, such as pubertal development or adult anthropometry. Women born in a defined geographic area of Sweden from 1973 through 1978, with verified preeclampsia exposure (n = 230) and nonexposure (n = 359) during fetal life, answered questions about anthropometric measures, smoking, parity, and age at menarche in a telephone interview in early adulthood. Compared with unexposed offspring, female offspring of women who had preeclampsia were lighter and shorter for gestational age, but in young adulthood there were no differences in height, body mass index, waist-to-hip ratio, or age at menarche. When analyzing the effects of other maternal and fetal characteristics, the results indicate that approximately 50% of the variance in final height was explained by parental heights and birth length for gestational age. Young-adult body mass index was weakly associated with maternal body mass index, maternal smoking, and birth weight for gestational age, which together explained 12% of the variance. Neither of the assessed maternal or fetal characteristics were significantly associated with age at menarche or waist-to-hip ratio. These data indicate that neither adult anthropometry nor age at menarche is in the causal pathway between intrauterine preeclampsia exposure and the reduced risk of breast cancer.
