Soy food consumption in relation to breast cancer modified by menopause status

Abstract

It has been found that lifestyle and diet are associated with the development of cancers. The mortality of breast cancer in Wuhan city is increasing, according to the statistics of recent years. This case control study was aimed to provide data for alimentary therapeutics for breast carcinomas. It included a case group (n = 196) and an age frequency-matched control group (n = 202). A validated food frequency questionnaire was used to obtain information on usual food consumption. The results indicate that intake of soy foods more than 5 times per week was associated with a decreased risk of breast cancer, especially in premenopausal women. The adjusted OR was 0.294 [95% CI was (0.158–0.546), P = 0.000]. Our results indicate that alimentary therapeutics for breast cancer can be adjusted by status of menopause.
