TI  - Assessment of dietary isoflavone intake among middle-aged Chinese men.
PG  - 1011-6
AB  - We evaluated the reproducibility and validity of the FFQ used in the Shanghai 
      Men's Health Study (SMHS) for assessing dietary isoflavone intake, using multiple 
      24-h dietary recalls (24-HDR) and urinary isoflavones as the reference criteria, 
      with data from the dietary validation study of the SMHS. A total of 196 study 
      subjects completed the 24-HDR and 2 FFQ and donated a quarterly spot urine sample 
      during the 1-y study period. Levels of urinary isoflavones were measured in a 
      random sample of 48 study participants. The correlation coefficient between the 2 
      FFQ administered 1 y apart was 0.50 for soy protein intake and ranged from 0.50 
      to 0.51 for isoflavone intake. The correlations of isoflavone intake from the 
      second FFQ with those from the multiple 24-HDR ranged from 0.38 (genistein) to 
      0.44 (glycitein), and the correlations with urinary isoflavone levels were 0.48 
      for total isoflavones, 0.44 for daidzein, 0.42 for genistein, and 0.54 for 
      glycitein. The intraclass correlation coefficients for the 4 spot urine samples 
      were 0.36, 0.42, and 0.40 for daidzein, genistein, and glycitein, respectively, 
      and 0.62, 0.68, and 0.55 for their metabolic products equol, dihydrodaidzein, and 
      O-desmethylangolensin, respectively. These results suggest that the SMHS FFQ can 
      reliably and accurately measure usual intake of isoflavones, and that the levels 
      of isoflavones in urine samples are relatively stable among men in Shanghai.
