Experimental Biology Meeting. Technical Abstract: Because of the importance of dietary surveys for estimating food intake, we tested the ability of 51 women to recall food intake. The 15 non-obese (NO) (BMI </= to 25) women were (mean +/- SD) 35.6 ñ 13.2 y with a BMI of 22.4 +/- 1.5, while the 36 obese (O) women were 43.5 +/- 11.1 y with a BMI of 33.1 +/- 5.5. We assessed dietary restraint (NO = 10.3 +/- 4.8 and O = 9.2 +/- 4.5) and tendency towards disinhibition (NO = 4.7 +/- 2.5 and O = 6.8 +/- 3.9), factors that determined food choices, and body composition. Subjects were allowed to choose all meals and snacks consumed during one day from a wide variety of foods in the BHNRC human study facility and they were permitted to eat as much or as little as desired. All meals were consumed under the supervision of a dietetian and snacks were packed for outside consumption. The USDA multiple pass method for dietary recall was administered by telephone the following day. Subjects were provided with food measuring devices and a copy of the USDA Food Model Booklet. Survey Net, a computer assisted coding system, was used to calculate actual food consumption from foods selected and plate waste. Accuracy of recall was determined along with macronutrient and micronutrient intake. Regression analysis was conducted to determine possible predictors of the accuracy of food and macronutrient intake.
