Abstract

OBJECTIVES
Isoflavone is a plant-derived compound, abundant in soy food, and its character is mixed estrogenic and antiestrogenic action, so it is highlighted as an alternative to hormone replacement therapy (HRT) in postmenopausal women. The purpose of this study is to establish a foundation for isoflavone study in the future, by estimating isoflavone intake in postmenopausal women and by recommending proper isoflavone intake.
METHODS
Isoflavone intake was estimated in a total of 189 Korean postmenopausal women over 50 years old, by using a food frequency questionnaire (FFQ). Data were statistically analyzed by t-test, and one-way ANOVA with Turkey's test.
RESULTS
The daily average isoflavone intake level was 21.94 +/- 19.96 mg. There is no significant difference in isoflavone intake according to age. About 60 percentile of postmenopausal women intake isoflavone under 20 mg a day, and 2 percentile of postmenopausal women intake about 80 mg isoflavone.
CONCLUSION
There was no definite precise amount of isoflavone for reliving postmenopausal symptom and health. But through this study, most postmenopausal women did not intake enough isoflavone, so they have to intake more isoflavone.
