Correction: Use of the Predictive Sugars Biomarker to Evaluate Self-Reported Total Sugars Intake in the Observing Protein and Energy Nutrition (OPEN) Study

In this article (Cancer Epidemiol Biomarkers Prev 2011;20:490–500), which was published in the March 2011 issue of Cancer Epidemiology, Biomarkers & Prevention (1), Table 1 contained errors in the values. The authors apologize for the and have submitted a corrected table (see Table 1).

Furthermore, the second paragraph of the Results section, page 494, was revised, as it discusses values reported in Table 1.

“The geometric means of total sugars and total sugars density by gender as estimated by the 2 instruments and the biomarker, as well as of urinary sucrose and fructose, are presented in Table 1. Reported intake of total sugars was about 30% lower on the FFQ for both men and women than by the biomarker-based estimate. Similarly, intake of sugars reported from 24HDRs was 16% and 20% lower than the biomarker in men and women, respectively. The self-reported density intakes of total sugars as estimated by the FFQ and 24HDRs were similar to biomarker-based estimates, for both men and women. It is important to note that the group means indicate the validity of instruments to measure intakes of absolute total sugars on a group level only and do not necessarily invalidate the use of these self-reported dietary instruments in a cohort study. If participants in a cohort misreport to the same extent and direction, then the instrument would still serve the purpose of ranking individuals with regard to their intake of total sugars. The greatest contributors to intake of total sugars in our participants were soft drinks (18%) and fruits (15%), as measured by FFQ, and soft drinks (22%) and cookies, cakes, and pies (13%), as measured by 24HDR.”
