| Outline of Final Research Achievements |
We conducted validation studies using PhIP level in hair to establish the method of exposure assessment for heterocyclic aromatic amines (HAAs) among Japanese and Japanese Brazilians. The validation study in Japanese suggested that our food frequency questionnaire (FFQ) for Japanese is reasonably valid for the assessment of HAA intake. On the other hand, the validation study in Japanese Brazilians suggested that the assessment of HAA intake by FFQ for Japanese Brazilians should be revised. When PhIP level in hair was used as exposure indicator, it was higher in Japanese Brazilians than Japanese.
