Seafood consumption and blood mercury concentrations in adults aged ≥20 y, 2007–2010

摘要: BACKGROUND Seafood is part of a healthy diet, but seafood can also contain methyl mercury-a neurotoxin. OBJECTIVE The objective was to describe consumption in US adults and explore the relation between blood mercury. DESIGN consumption, obtained from food-frequency questionnaire, mercury data were available for 10,673 who participated 2007-2010 NHANES-a cross-sectional nationally representative sample population. categorized by type (fish or shellfish) frequency (0, 1-2, 3-4, ≥5 times/mo). Linear trends geometric mean concentrations tested. Logistic regression analyses examined odds ≥5.8 μg/L (as identified National Research Council) based on specific consumed (included model as continuous variables) adjusted sex, age, race/Hispanic origin. RESULTS In 2007-2010, 83.0% ± 0.7% (±SE) preceding month. consuming seafood, concentration increased (P < 0.001). 4.6% 0.39% had μg/L. Results logistic showed no association with shrimp = 0.21) crab 0.48) highly significant positive high-mercury fish (adjusted OR per unit monthly consumption: 4.58; 95% CI: 2.44, 8.62; P 0.001), tuna OR: 1.14; 1.10, 1.17; salmon 1.09, 1.20; other 1.12; 1.08, 1.15; CONCLUSION Most consume associated tuna, salmon, fish, seafood.
