Validity and reproducibility of a computerised tool for assessing the iron, calcium and vitamin C intake of Belgian women.
Eur J Clin Nutr. 2004 Sep; 58(9):1297-305.EJ

Abstract

OBJECTIVE

To determine the relative validity of a newly developed iron intake assessment tool, designed specifically to assess iron, calcium and vitamin C intake.

DESIGN

Estimates of iron, calcium and vitamin C intake from a computerised iron intake assessment tool compared with those from 11-day estimated dietary records.

SETTING

Region of Ghent (N= +/- 225,000), a city in Flanders, the Dutch-speaking part of Belgium.

SUBJECTS

In all, 50 women aged 18-39 y, participating in a large-scale epidemiological study on iron intake and iron status.

MAIN RESULTS

Mean dietary iron intake from the 11-day food record, the unadjusted dietary iron intake assessment tool and the adjusted tool was, respectively, 10.5 +/- 2.7, 10.4 +/- 4.3 and 9.6 +/- 2.9 mg. For the different nutrients, the correlation coefficients vary from 0.45 to 0.60 for adjusted intake. The mean difference of iron intake by the two methods (0.8 +/- 2.9 mg) did not differ significantly from zero. The new method correctly classified 38% (iron), 38% (calcium) and 58% (vitamin C) of the subjects to the correct tertile. The correlation coefficients ranged from 0.48 for adjusted vitamin C intake to 0.73 for adjusted calcium intake between two administrations.

CONCLUSION

The newly developed instrument can be used to assess mean group intakes of iron, calcium and vitamin C in women consuming a Western diet. However, since the ranking capability of the new tool is rather weak, further refinement of the tool is required to produce a robust method for assessing iron, calcium and vitamin C intakes of individuals.
