Reporting bias is a well‐recognized limitation of dietary recalls. Parent recall of child diet is additionally challenged because parents are often asked to report meals eaten when they are not present. We explored a method for identifying and correcting implausible energy intake (EI) using baseline data from an intervention trial of 324 children, 2–5 years of age. Reported energy intake (rEI) was derived from 2 weekday parent‐reported 24‐hour dietary recalls. Sex‐ and gender‐specific plausible cutoffs were derived for rEI as a percentage of predicted energy requirement (pER) using Dietary Reference Intake equations for estimated energy requirement (eER) that take into account age, weight, height, and physical activity. We calculated ±1 standard deviation (SD) cutoffs. Because parents were not expected to report meals for children while in childcare, meals between 9am–5pm were excluded. eER was adjusted to reflect this exclusion by assuming 50% of meals were eaten at child care. Using the ±1 SD cutoff, 191 children had plausible rEI. In the total sample, there was over‐reporting of EI for 2‐year‐old children (mean rEI as % pER, 105 ± 39), while under‐reporting was observed for 3–5 year old children (rEI/pER < 100%). The ±1 SD cutoff moved rEI closer to pER in both groups. The methods used in this study offer an approach for overcoming challenges that could help lead to more accurate conclusions of dietary associations. Grant Funding Source : NHLBI Grant No. R01HL091093
