The 24-hr dietary recall
interviews were entered using the NDS-R 2008 (The Nutrition Coordinating Center, Minneapolis, MN, USA).
The study sample included all participants [greater than or equal to] 6 years old who completed a 24-hr dietary recall
survey and provided a urine sample for phthalate or BPA analysis.
Using cross-sectional data from 2,374 participants in the 2003-2004 National Health and Nutrition Examination Survey, the authors estimated associations between dietary intake (assessed by 24-hr dietary recall
) of different food types (meat, poultry, fish, fruit, vegetables, and dairy) and phthalate metabolites measured in urine.
Dietary intake was assessed in NHANES using two 24-hr dietary recall
face-to-face interviews, a 24-hr dietary recall
conducted by telephone 3-10 days after the interview, and a food frequency questionnaire.
Blood organic/methyl mercury reflects methyl mercury intake from fish and shellfish as determined from a methyl mercury exposure parameter based on 24-hr dietary recall
, 30-day food frequency, and mean concentrations of mercury in the fish/shellfish species reported as consumed (multiple correlation coefficient > 0.5).
