目的：方法：将1995 ~ 2000年日本全国营养调查（J-NNS）的样本分布与日本全国人口普查的样本分布进行比较，分析性别、年龄、居住地、家庭成员数等方面的差异。在调查样本中，与全国人口普查分布相比，女性比例高出1%至2%，20至39岁的个人比例低出几个百分点，对农村地区略有偏向。在20至59岁的个人中，生活在单人家庭的个人比例是全国人口普查发现的50%至66%。观察到的样本和人口之间的差距是最小的，除了在个人谁lived alone.Conclusions的比例的情况下：在J-NNS中使用的样本一般是代表整个日本人口的个人在单人家庭除外。(c)2005年爱思唯尔公司All rights reserved.
Objective: We examined the representativeness of the sample used in the National Nutrition Survey in Japan (J-NNS).Methods: The distribution of the J-NNS sample from 1995 to 2000 was compared with that of the national census with respect to gender, age group, place of residence, and number of household members.Results: In the survey sample, as compared with the national census distributions, the proportion of females was 1% to 2% larger, the proportion of individuals who were 20 to 39 y of age was a few percentages smaller, and a slight bias toward rural areas was seen. Among individuals who were 20 to 59 y of age, the proportion of individuals who lived in single-person households was 50% to 66% of that found in the national census. Observed disparities between the sample and the population were minimal except in the case of the proportion of individuals who lived alone.Conclusions: The sample used in the J-NNS is generally representative of the entire Japanese population with the exception of individuals in single-person households.
