Abstract
Background:
Estimating dietary intake is important for both epidemiological and clinical studies, but often lacks accuracy.
Objective:
To investigate the accuracy and validity of energy intake estimated by an easy-to-use semiquantitative food record (EISQFR) compared to total energy expenditure (TEE) estimated by doubly labelled water technique (EEDLW).
Design:
TEE was measured in 29 nonobese subjects using the doubly labelled water method over a period of 14 days. Within this period, subjects reported their food consumption by a newly developed semiquantitative food record for 4 consecutive days. Energy intake was calculated using the German Food Code and Nutrition Data Base BLS II.3.
Results:
A good correlation was observed between EISQFR and EEDLW (r=0.685, P<0.001). The mean difference between EISQFR and EEDLW was -1.7
2.6 MJ/day (-1421%, P=0.002). An underestimation of EISQFR <10% was observed in nine subjects (31%), of 10–20% in six subjects (21%), and of >20% in nine subjects (31%). In five subjects (17%), an overestimation of EISQFR was observed.
Conclusions:
The easy-to-use semiquantitative food record provided good estimates of EI in free-living and nonobese adults without prior detailed verbal instructions. The presented food record has limitations regarding accuracy at the individual level.
