Background: Being breastfed has established benefits for infant health, but its long-term effects on adult diseases, including cancer, remain underexplored. We examined associations between being breastfed in infancy and the risks of common cancers.
Methods: Data from 339,115 participants (191,117 women) enrolled in the UK Biobank with self-reported breastfeeding data were linked to national cancer registries.
Objective: Breastfeeding improves cognitive ability in childhood, but the long-term impact on socioeconomic outcomes remains unknown. We examined associations between durations of predominant and any breastfeeding and educational attainment, income, and labor force participation in adulthood, and whether these varied by maternal education.
Study Design: Prospective cohort study.
Background: The early life factors of birthweight, child weight, height, body mass index (BMI) and pubertal timing are associated with risks of breast cancer. However, the predictive value of these factors in relation to breast cancer is largely unknown. Therefore, using a machine learning approach, we examined whether birthweight, childhood weights, heights, BMIs, and pubertal timing individually and in combination were predictive of breast cancer.
