Clinical Trial Summary

The purpose of this study was to examine the relationship between indices of overall diet quality and incident breast cancer risk in a large prospective cohort of women.


Clinical Trial Description

This study examined the role of overall diet quality on the risk of developing invasive breast cancer among 96,959 women in the California Teachers Study, in which 4,826 women were diagnosed with breast cancer during follow-up (1995-2011). Participants' dietary habits were recorded at baseline (1995) using a 103-item Block95 Food Frequency Questionnaire to allow for the assessment of overall diet quality. Specifically, diet quality was characterized by the Alternate Mediterranean Diet (aMED), Alternative Healthy Eating Index-2010 (AHEI-2010), Dietary Approaches to Stop Hypertension (DASH), and Paleolithic Index scores. Associations between diet quality and the risk of developing breast cancer were examined using multivariate Cox proportional hazard regression models to provide hazard ratios and corresponding 95% confidence intervals. ;
