Interpretive Summary:

Technical Abstract: Background: Current federal dietary guidance recommends regular consumption of seafood (fish + shellfish) for health; however, little is known about how well Americans meet guidelines, particularly population subgroups. Objectives: To describe prevalence of seafood consumption and, among consumers, amounts of any seafood, fish, and shellfish eaten by subgroups of Americans (sex, age group, income and education level, and race-ethnicity). Seafood intake was also compared to federal guidance. Methods: Data from the WWEIA, NHANES survey years 2005-2010 were analyzed using logistic regression to test whether consumers (%) varied within subgroups. Usual intake methodology estimated amounts consumed and differences within subgroups were tested using Z-tests. Results: Of US adults 19+, 84% reported consuming seafood over the past 30 days, 74% reported fish, and 54% reported shellfish. Younger age and lower income and education levels were associated with lower odds of being a seafood consumer (P < 0.0001). In seafood consumers, the average amount eaten was 22.6 ± 0.8 g/d. Women and individuals of lower age and education levels consumed less. Similar patterns were seen when subgroups were stratified by sex. 78% - 92% of adults did not meet federal recommendations when estimated by energy requirements. Conclusions: Americans have sub optimal levels of seafood intake; interventions to increase frequency and amount of seafood consumption, especially in the lowest-consuming subgroups, are critically needed.
