Long-chain omega-3 fatty acid serum concentrations across life stages in the USA: an analysis of NHANES 2011-2012.

ABSTRACT:

Objective

To determine reference ranges of circulating long-chain (LC) omega-3 fatty acids: eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA) and docosahexaenoic acid (DHA) in a nationally representative population of Americans. To provide context, serum concentrations of LC omega-3 were compared with concentrations associated with consuming the recommended amount of EPA and DHA by the Dietary Guidelines for Americans (DGA) and the Omega-3 Index (EPA+DHA).

Design

Cross-sectional population-based study.

Setting

The National Health and Nutrition Examination Survey 2011-2012 cycle.

Participants

Participants with fatty acids measured in serum: 945 children, age 3-19 years, and 1316 adults, age 20 and older.

Main measure
