What is already known about this subject:
- Population-based studies have shown that intake of fatty acids from the diet is associated with a range of health conditions. Therefore, the level of fatty acid intake in the population and the reliability of the Food Frequency Questionnaire (FFQ) as a rapid and easily accessible screening tool for fatty acid intake merit investigation. We aimed to assess the relationship between the use of an objective laboratory test marker to assess the level of dietary fatty acid intake in a cohort of adolescents collected using the Commonwealth Scientific and Industrial Research Organization (CSIRO) Food Frequency Questionnaire.
What this study adds
- A cross-sectional study used data from 1155 adolescents (2nd generation) enrolled in the Raine study with 14 years of follow-up. Agreement between dietary fatty acid intake and objective laboratory test markers for each fatty acid level was examined. There was high agreement between dietary intake and laboratory test marker levels derived from the FFQ, although there was some bias between the two results in individuals with high intake levels. the FFQ could potentially be used as a tool to identify some individuals with inadequate fatty acid intake.
