Hypothesis
What is the prevalence and predictors of soy consumption among women with breast cancer?
Conclusion
The study found that isoflavone intake among breast cancer patients was quite variable, with some patients reporting no soy intake at all.
Supporting Evidence
- The mean daily intake of genistein was 11.6 mg and daidzein was 7.6 mg.
- Thirty-five patients reported no soy intake.
- Soy milk and pills containing soy were the largest contributors to isoflavone intake.
Takeaway
This study looked at how much soy women with breast cancer eat, and found that some eat a lot while others eat none at all.
Methodology
A cross-sectional study using a soy food frequency questionnaire completed by 100 women with breast cancer.
Potential Biases
The sample may have a higher prevalence of soy use due to the nature of the patient population seeking care at the institution.
Limitations
The study sample was limited to English-speaking Caucasian patients, which may not represent the broader population of breast cancer patients.
Participant Demographics
The majority of participants were white (81%), with a mean age of 50.5 years and a mean BMI of 27.3.
