Methodology: Citation Relevancy Criteria - NCS Dietary Assessment Literature Review
To pass the initial screen for ordering the full text article, the title and/or abstract met the following criteria:
- Was published in 1982 or later;
- Reviewed primary studies, or was a primary study using an instrument to assess food, supplement, and/or food born contaminant intake;
- Contained (or at least presented an adequate impression that the full article might provide) discussion of assessment in non-institutionalized pregnant or lactating women, or children ages 0-18 years of age;
- Contained (or at least presented an adequate impression that the full article might provide) discussion of assessment of college student populations that include 18 year old students;
- Included a target population relevant to the characteristics of the proposed NCS cohort (and therefore included studies performed on European populations but excluded studies in most third world populations);
- Did not target populations with eating disorders or specific disease conditions, such as cerebral palsy, diabetes, kidney disease, or developmental delays;
- If the citation was a supplement-intervention study, it included an instrument to measure baseline supplement usage or included a biochemical marker validating supplement usage.
- If the citation was an epidemiological study that included 16 to 18 year old participants as adults, it reported and analyzed data on adolescents separately;
- If the citation was an analysis of published data from CSFII or NHANES, the abstract discussed dietary assessment methodology or dietary data collection issues; and
- If the citation was a review article, it discussed dietary assessment methodology that may have relevance to the literature review's target population.
