Soya food intake and risk of endometrial cancer among Chinese women in Shanghai

[Guest guest]

Taken from:

 

Objective To evaluate the association of intake of soya food, a rich

source of phytoestrogens, with the risk of endometrial cancer.

 

Design Population based case-control study, with detailed

information on usual soya food intake over the past five years

collected by face to face interview using a food frequency

questionnaire.

 

Setting Urban Shanghai, China.

 

Participants 832 incident cases of endometrial cancer in women aged

of 30 to 69 years diagnosed during 1997-2001 and identified from the

Shanghai Cancer Registry; 846 control women frequency matched to

cases on age and randomly selected from the Shanghai Residential

Registry.

 

Abstract

 

Main outcome measures Odds ratios for risk of endometrial cancer in

women with different intakes of soya foods.

 

Results Regular consumption of soya foods, measured as amount of

either soya protein or soya isoflavones, was inversely associated

with the risk of endometrial cancer. Compared with women with the

lowest quarter of intake, the adjusted odds ratio of endometrial

cancer was reduced from 0.93 to 0.85 and 0.67 with increasing

quarter of soya protein intake (P for trend 0.01). A similar inverse

association was observed for soya isoflavones and soya fibre intake.

The inverse association seemed to be more pronounced among women

with high body mass index and waist:hip ratio.

 

Conclusion Regular intake of soya foods is associated with a reduced

risk of endometrial cancer.
