The value of a nutritional biomarker rests in its ability to accurately assess the nutritional status of an individual or population. This has both clinical and public health implications. The correct...
Applying inappropriate cutoffs leads to misinterpretation of folate status in the US population
deficiency insufficiency microbiologic assay'NHANES'radioprotein-binding assay
2018/12/19
Background: Folate cutoffs for risk of deficiency compared with possible deficiency were originally derived differently (experimental compared with epidemiologic data), and their interpretations are d...

with a scaling factor ranging between b=1.66 and b=6.41. Both the maximum number of model iterations, imax, and n correlated positively with soil organic carbon. Knowing the limits of fractal behavio...
Suggested lower cutoffs of serum zinc concentrations for assessing zinc status: reanalysis of the second National Health and Nutrition Examination Survey data (1976–1980)
Serum zinc zinc deficiency NHANES II
2017/1/4
The risk of zinc deficiency in populations can be estimated by comparing serum zinc data with statistically defined lower cutoffs derived from a presumably healthy population. Serum zinc data are avai...
Body fat percentages measured by dual-energy X-ray absorptiometry corresponding to recently recommended body mass index cutoffs for overweight and obesity in children and adolescents aged 3–18 y
