估计某种营养素相对于另一种营养素的通常摄入量的人口分布需要确定个体水平的比率。如果每日摄入量数据可用，就像 24 小时饮食回忆一样，这些比率可以通过以下两种方式之一确定：作为通常的摄入量比率或通常的摄入量比率。这些比率中的每一个都有其自己的含义和确定；通常摄入量的比率在概念上与从 FFQ 数据获得的确定一致。我们提出了一种估计通常摄入量比率的方法，该方法使用所讨论的两种营养素摄入量的双变量模型。将该方法应用于 2001-2004 年的 NHANES 数据，得出了总脂肪中通常能量摄入量的百分比、饱和脂肪中通常能量摄入量的百分比以及每 1000 kcal (4184 kJ) 日常能量摄入量中钠摄入量的估计分布。估计了总人口和年龄-性别亚组的分布。大约 60% 的成年人（> 19 岁）的通常总脂肪摄入量在总能量 20-35% 的推荐范围内，但只有 34% 的成年人通常摄入饱和脂肪
Estimating the population distribution of the usual intake of a nutrient relative to that of another nutrient requires determination of individual-level ratios. If intake data are available on a per-day basis, as with 24-h dietary recalls, those ratios can be determined in 1 of 2 ways: as the usual ratio of intakes or the ratio of usual intakes. Each of these ratios has its own meaning and determination; the ratio of usual intakes is conceptually consistent with determinations obtained from FFQ data. We present a method for estimating the ratio of usual intakes that uses bivariate modeling of the 2 nutrient intakes in question. Application of the method to the NHANES data for the years 2001-2004 yielded estimated distributions for percent of usual energy intake from total fat, percent of usual energy intake from saturated fat, and usual sodium intake per 1000 kcal (4184 kJ) of usual energy intake. Distributions for both the total population and for age-gender subgroups were estimated. Approximately 60% of adults (>19 y) had a usual total fat intake that was within the recommended range of 20-35% of total energy, but only similar to 34% had a usual saturated fat intake
