Abstract
To compare estimates from one day with usual intake estimates to evaluate how the adjustment for within-person variability affected nutrient intake and adequacy in Mexican children. In order to obtain usual nutrient intakes, the National Cancer Institute's method was used to correct the first 24 h dietary recall collected in the entire sample (n 2045) with a second 24 h recall collected in a sub-sample (n 178). We computed estimates of one-day and usual intakes of total energy, fat, Fe, Zn and Na. 2012 Mexican National Health and Nutrition Survey. A total of 2045 children were included: 0-5·9 months old (n 182), 6-11·9 months old (n 228), 12-23·9 months old (n 537) and 24-47·9 months old (n 1098). From these, 178 provided an additional dietary recall. Although we found small or no differences in energy intake (kJ/d and kcal/d) between one-day v. usual intake means, the prevalence of inadequate and excessive energy intake decreased somewhat when using measures of usual intake relative to one day. Mean fat intake (g/d) was not different between one-day and usual intake among children >6 months old, but the prevalence of inadequate and excessive fat intake was overestimated among toddlers and pre-schoolers when using one-day intake (P6 months. There was overall low variability in energy and fat intakes but higher for micronutrients. Because the usual intake distributions are narrower, the prevalence of inadequate/excessive intakes may be biased when estimating nutrient adequacy if one day of data is used.

One-day means v. usual intake means of energy intake were not significantly different for any of the age groups except for toddlers, where the mean from one-day intake was slightly overestimated compared with the usual intake mean
The prevalence of inadequate intake of energy was overestimated when using measures of one day among infants 0–5·9 months old, toddlers 12–23·9 months old and pre-schoolers 24–47·9 months old, P < 0·05; whereas the prevalence of excessive intake was overestimated among infants 6–11·9 months old and pre-schoolers 24–47·9 months old when using measures of one-day intake, P < 0·05
Summary
Study population: the Mexican National Health and Nutrition Survey 2012 The Mexican National Health and Nutrition Survey (NHNS) 2012 was conceived with the aim of characterizing the health and nutritional status of the Mexican population. The NHNS 2012 is a cross-sectional, probabilistic population-based survey with a multistage and stratified sampling, which represents the population of Mexico[26]. Dietary intake and nutrient data collection Dietary intake was collected by trained interviewers using a 24 h recall in a stratified nationally representative subsample of the population (approximately one-sixth of the total population included in the NHNS 2012). A sub-sample was randomly selected by 6-month age strata during sampling development to report a second day of dietary intake. This second day was collected on a separate visit at least two days after the first recall. From a total of 2057 infants, toddlers and pre-schoolers aged
