    • Longitudinal changes in the accuracy of reported energy intake in girls 10-15 y of age
      Bandini, Linda G.; Must, Aviva; Cyr, Helene; Anderson, Sarah E.; Spadano-Gasbarro, Jennifer L.; Dietz, William H. (2003-09-26)
      BACKGROUND: Dietary records are often used to estimate individual energy needs and population energy requirements. However, significant underreporting of total energy intake (EI) has been found when EI is compared with total energy expenditure (EE) measured by doubly labeled water. OBJECTIVE: This study aimed to determine whether the accuracy of reported EI decreases from middle childhood to adolescence. DESIGN: In this longitudinal study of 26 healthy girls, EI and EE were measured at ages 10, 12, and 15 y. Accuracy of reported EI (EI/EE x 100%) was calculated at each age. At study entry, girls had a mean (+/- SD) body mass index (in kg/m(2)) of 16.8 +/- 1.9 and percentage body fat of 24.0 +/- 4.6%. Measurements of EI were a 7-d dietary record and those of EE were by doubly labeled water. RESULTS: As they got older, girls tended to report EI less accurately: the average accuracy was 88 +/- 13% at age 10 y, 77 +/- 21% at age 12 y, and 68 +/- 17% at age 15 y. The declines in reporting accuracy from age 10 y to age 12 y and from age 10 y to age 15 y were statistically significant (P = 0.03 and P = 0.001, respectively). Reporting accuracy also declined from age 12 to age 15 y but not significantly. When percentage body fat was added to the model, results were essentially unchanged. CONCLUSION: Because of the decline in EI reporting accuracy with age, the use of EI data obtained from dietary records in adolescent girls will result in substantial underestimation of energy needs.

    • Nutrient Intake Report: a coordination of patient dietary assessment between physicians and registered dietitians
      Olendzki, Barbara C.; Hebert, James R.; Hampl, Jeffrey S.; Scribner, Kelly B.; Ockene, Ira S. (1998-10-27)
      The Nutrient Intake Report (NIR) is based on a 7-day dietary recall questionnaire used previously in research for dietary assessment and adapted for clinical use. Used to provide information and counseling as part of total patient care, the NIR acts as a cornerstone for dietary education and interaction between physician, registered dietitian, and patient. The NIR is ordered by physicians or registered dietitians, scanned and assessed by a registered dietitian, and incorporated into the laboratory section of the medical record. It documents the patient's dietary intake in the context of his or her diagnosis and general health status. The NIR also opens a dialogue between physicians and registered dietitians. Incorporation of the NIR into the medical record makes the work of the registered dietitian available to other health practitioners, which is welcome in an era when licensing and reimbursement are contingent on systematic documentation of dietary assessment and its role in patient care.

    • Use of recovery biomarkers to calibrate nutrient consumption self-reports in the Women's Health Initiative
      Neuhouser, Marian L.; Tinker, Lesley; Shaw, Pamela A.; Schoeller, Dale; Bingham, Sheila A.; Van Horn, Linda; Beresford, Shirley A. A.; Caan, Bette J.; Thomson, Cynthia; Satterfield, Suzanne; et al. (2008-05-15)
      Underreporting of energy consumption by self-report is well-recognized, but previous studies using recovery biomarkers have not been sufficiently large to establish whether participant characteristics predict misreporting. In 2004-2005, 544 participants in the Women's Health Initiative Dietary Modification Trial completed a doubly labeled water protocol (energy biomarker), 24-hour urine collection (protein biomarker), and self-reports of diet (assessed by food frequency questionnaire (FFQ)), exercise, and lifestyle habits; 111 women repeated all procedures after 6 months. Using linear regression, the authors estimated associations of participant characteristics with misreporting, defined as the extent to which the log ratio (self-reported FFQ/nutritional biomarker) was less than zero. Intervention women in the trial underreported energy intake by 32% (vs. 27% in the comparison arm) and protein intake by 15% (vs. 10%). Younger women had more underreporting of energy (p = 0.02) and protein (p = 0.001), while increasing body mass index predicted increased underreporting of energy and overreporting of percentage of energy derived from protein (p = 0.001 and p = 0.004, respectively). Blacks and Hispanics underreported more than did Caucasians. Correlations of initial measures with repeat measures (n = 111) were 0.72, 0.70, 0.46, and 0.64 for biomarker energy, FFQ energy, biomarker protein, and FFQ protein, respectively. Recovery biomarker data were used in regression equations to calibrate self-reports; the potential application of these equations to disease risk modeling is presented. The authors confirm the existence of systematic bias in dietary self-reports and provide methods of correcting for measurement error.
