COMPARISON OF MULTIPLE-PASS 24-HOUR RECALL ESTIMATES OF ENERGY-INTAKEWITH TOTAL-ENERGY EXPENDITURE DETERMINED BY THE DOUBLY LABELED WATER METHOD IN YOUNG-CHILDREN

Objective This study determined the accuracy of the multiple-pass 24-h our recall method for estimating energy intake in young children by co mparing it with measurements of total energy expenditure made using th e doubly labeled water method. Design Three multiple-pass 24-hour reca lls were obtained over a 14-day period to estimate mean energy intake. Total energy expenditure was measured over the same 14-day period und er free-living conditions using the doubly labeled water technique. Su bjects/setting Twenty-four children between the ages of 4 and 7 years were tested at the General Clinical Research Center/Sims Obesity Nutri tion Research Center at the University of Vermont. Statistical analysi s t Tests, paired t tests, Pearson product-moment correlation coeffici ents, pairwise comparison to show relative bias and limits of agreemen t, and regression analysis were used to test the relationships among s tudy variables. Results No difference was found between:S-day mean ene rgy intake and total energy expenditure for the group (t=2.07, P=.66). The correlation between individual measures of energy intake and tota l energy expenditure was not statistically significant (r=.25, P=.24). Conclusions Data from 3 days of multiple-pass 24-hour recalls were su fficient to make valid group estimates of energy intake. The method wa s not precise for inclinical measurements of energy intake.
