dc.description.abstract | Incidence rates of breast cancer (BC) are increasing in South Africa. The aim of this study was to investigate the association between dietary
intake and BC risk in black South African women. The study population included 396 BC cases and 396 population-based controls matched on
age and residence, participating in the South African Breast Cancer study. Diet was assessed using a validated quantified FFQ from which
twelve energy-adjusted food groups were formed and analysed. OR were estimated using conditional logistic regressions, adjusted for
confounding factors, comparing highest v. lowest median intake. Fresh fruit consumption showed an inverse association with BC risk (OR=0·3,
95 % CI 0·12, 0·80) in premenopausal women, whilst red and organ meat consumption showed an overall inverse association with BC risk
(OR=0·6, 95 % CI 0·49, 0·94 and OR=0·6, 95 % CI 0·47, 0·91). Savoury food consumption (sauces, soups and snacks) were positively
associated with BC risk in postmenopausal women (OR=2·1, 95 % CI 1·15, 4·07). Oestrogen receptor-positive stratification showed an inverse
association with BC risk and consumption of nuts and seeds (OR=0·2, 95 % CI 0·58, 0·86). Based on these results, it is recommended that black
South African women follow a diet with more fruit and vegetables together with a decreased consumption of less energy-dense, micronutrientpoor foods such as savoury foods. More research is necessary to investigate the association between BC risk and red and organ meat
consumption. Affordable and practical methods regarding these recommendations should be implemented within health intervention strategies | en_US |
