Objective: The purpose of this study was to describe food consumption practices of Filipino-American adults, to describe how they respond to a food frequency questionnaire (FFQ) as a function of acculturation and sex, and to suggest modifications to the FFQ to improve dietary assessment among Filipino-Americans. Methods: Twenty-one Filipino-American women and 14 Filipino-American men (aged 30-60 years) who varied on acculturation level were recruited from the general community of San Diego, California. Participants completed a focus group and rated the Fred Hutchinson Food Frequency Questionnaire. Results: The most commonly eaten food items among Filipino-Americans were white rice, fish or meat, vegetables, and fruit. Most (76%) participants reported that the Fred Hutchinson Food Frequency Questionnaire lacked commonly eaten Filipino-American food. Conclusions and Implications: Commonly consumed food, such as "adobo," "lumpia," and "pansit," might be added to a revised FFQ; doing so may improve recall and face validity among Filipino-Americans.
