Studies suggest a positive association between dietary energy density (DED) and body weight. Evidence in children is inconclusive. Our objective was to compare usual DED distributions of non‐overweight and overweight children adjusting to minimize random and systematic errors. We used 24 hour recall data from 2367 children between 5 and 11 y old from the 2012 National Health and Nutrition Survey. Repeated measures of 24 h recalls were obtained in a random sample (10%) to estimate usual intake distributions using the Iowa State University method. Implausible dietary reports were identified. The relationship between DED and body weight status was evaluated using multivariate linear regression models. 35.1% of the children in the sample were overweight (including obesity). After adjustment for covariates, DED of overweight children was 2.9 kcal/100g higher than that of non‐overweight children (p=0.066). Adjusting also for measurement error and restricting analysis to plausible reporters, DED was 9.2 kcal/100 g higher in overweight compared to non‐overweight children (p<0.0001). Results show a positive association between DED and body weight in Mexican children and the importance of appropriate adjustments for random and systematic errors in dietary associations. They also suggest the need of strategies to reduce DED, such as a tax on energy‐dense low‐quality foods to tackle obesity in Mexico.
