ABSTRACT
OBJECTIVE:
To evaluate the representativeness of single measurement of urinary soy-isoflavone concentrations for the assessment of long-term intake levels.METHODS:
Five urine samples taken from 14 Japanese female subjects over 2-3 months were measured for daidzein and equol by gas chromatography-mass spectrometry (GC-MS).RESULTS:
Geometric mean daidzein and equol concentrations of 14 subjects were 582 and 2.66 µg/g creatinine, respectively. Intra-class correlation coefficients for daidzein and equol were 0.355 (95% CI 0.130-0.649) and 0.741 (0.551-0.891), respectively.CONCLUSION:
Single measurement of urinary equol is effective for the assessment of long-term equol status of Japanese subject while that of daidzein is not.Palavras-chave
