Literacy and Body Fatness are Associated with Underreporting of Energy Intake in US Low-Income Women Using the Multiple-Pass 24-hour Recall: A Doubly Labeled Water Study
Section snippets
Sample
Thirty-five low-income women between the ages of 19 and 46 years residing in Burlington, Vt, and surrounding rural areas were recruited to participate in the study. Low income was defined as a monthly household income at or below 130% of the federal poverty level (13). This cutoff number was selected because it is the income eligibility cutoff point for the federal food stamp program. Thus, all the volunteers were eligible for food stamps, although participation in the program was not required.
Results
Table 1 presents a summary of the subjects’ characteristics. The mean change in subjects’ weight (mean=0.2 kg, range= −1.60 to 2.8 kg) over the 14-day period was not significantly different from zero (P=.2), which indicates that the group was weight stable during the study period. No difference was noted between the mean 2-day energy intake as estimated from the in-person recalls (2,173±656 kcal) and the mean 2-day energy intake as estimated from the telephone recalls (2,253±688 kcal) (P=.36).
Discussion
Two major findings are evident in this study. First, the multiple-pass 24-hour recall underestimated energy intake in this sample of weight-stable, low-income women. Second, percentage body fat and the ability to read and spell as measured by the WRAT were the best predictors of energy intake misreporting in the sample. These 2 variables had opposing effects on underreporting. Underreporting worsened as percentage body fat increased and was diminished as the WRAT scores improved.
The doubly
Applications
In this sample of low-income women, the multiple-pass 24-hour recall did not generate a group measure of energy intake that was accurate or unbiased. These findings, as well as those from the literature on dietary intake underreporting, raise serious challenges for nutrition professionals. It has become untenable for researchers to make conclusions about associations between diet and health unless the problem of underreporting is considered in the dietary survey data.
