Objective:
To investigate if the diet quality and its components are associated with breast cancer risk.
Methods:
A case-control study was conducted with 332 women, 114 who were diagnosed with breast cancer, and 218 control individuals. Groups were matched for age, body mass index, and menopausal status. The quality of diet was assessed using Brazilian Healthy Eating Index Revised (BHEI-R) and its components. Food consumption was measured through three 24-h dietary recalls and assessed using the NDS-R software. For statistical analyses, it was performed an adjusted logistic regression, estimation of the Odds Ratio (OR), and 95% confidence interval (95%CI), with a p-value <0.05.
Results:
The BHEI-R score, classified into quartiles, did not differ between groups in the lowest quartile of diet quality (p=0.853). The components total cereals (p=0.038), saturated fat (p=0.039) and Gord_AA (fat, alcohol, and added sugar) (p=0.023) had higher scores among the case group. The scores for total fruits (p=0.010) and milk and dairy products (p=0.039) were higher among the control group. The BHEI-R components and the quality of diet were not associated with the outcome.
Conclusion:
Diet quality, assessed by the BHEI-R and its components, was not associated with breast cancer.
