This study was conducted to estimate the prevalence of nutrient inadequacy among Koreans using 2001 National Health and Nutrition Survey (KHNS) (N=9,960), with one‐day dietary intake data collected by 24 hour recall method. Usual intake was obtained after adjusting for daily variation of nutrient intakes. Daily variations of intakes were adjusted with variance ratios using the subset of population with two 24‐hour recalls collected from Seasonal KNHANES 2002 (N=3,955). The method developed by the Iowa State University was used to estimate usual dietary intake distributions for a population. We assumed that the proportion of within‐individual variance is relatively stable over time. Distributions of usual intakes for 14 nutrients were derived and proportions of population below EAR of Korean DRIs, by 18 gender/age groups, were calculated. The estimated prevalence of inadequate intakes determined by % of subjects below EAR was 74% for calcium, 41% for riboflavin, and 16% for vitamin A. For approximately 99% of population in this study, sodium intakes were greater than the intake goal (2mg/d). Older group (age>65) had higher probability of inadequacy for almost all nutrients, but iron was problem for younger age group. Adjusting intake data for daily variation reduced the proportion of population below EAR in all nutrients, except in calcium, which resulted in increase by 3.7%, among Koreans.
