Age at First Full-term Pregnancy and Other Reproductive Factors Are Associated with Mammographic Breast Density in Postmenopausal Women: A Study in Flanders, Belgium.

ABSTRACT:

Abstract

This study evaluated the association between age at first full-term pregnancy (FFTP) and mammographic breast density (MBD) in postmenopausal women. A total of 1,034 women, ages 50 to 69 years, were recruited from the Flemish (Belgium) population–based breast cancer screening program. Participants completed a questionnaire on lifestyle and reproductive factors. From mammography, we assessed the percentage glandular tissue of the total breast volume (GLAND), the volumetric breast density (VBD), and the Breast Imaging Reporting and Data System (BI-RADS) density classification. For statistical analysis, we used the piecewise linear regression model. The average age at FFTP was 26.1 years. Among women with an FFTP > 25.7 years, an each year increase in FFTP age was associated w
