青少年儿童的营养问题已经引起我国各级卫生、教育部门和社会各界的普遍重视。为了科学地指导这方面的工作并为了促进这方面的研究工作,制定合理、简便、定量、准确、全国统一的营养评价标准是亟待解决的问题。一九八○年大连市、沈阳市等地分别制定了本地区中小学生身高标准体重评价表。其方法是选身高在120—170厘米范围内,每一厘米身高男女各200例,共计2万多例样本进行测试、统计运算后制定的。这样做虽然所定标准较适合当地情况,但是要耗费大量的人力、物力、财力,需要较长时间,且不是全国范围的数据资料,不便制定全国统一的评价标准,全国各地有关营养方面的资料可比性差,不利于发现典型,总结经验,推动这一工作向前发展。由于用“身高标准体重”作为反映现实营
The nutrition of adolescent children has drawn universal attention from the health, education and social sectors at all levels in our country. In order to guide this work scientifically and to promote the research in this aspect, it is an urgent problem to develop a nutrition evaluation standard which is reasonable, simple, quantitative, accurate and uniform. In 1980, Dalian City and Shenyang City, respectively, formulated the height and weight standards for primary and secondary school students in this area. The method is to elect body height in the range of 120-170 cm, 200 cm in height for each centimeter for men and women, a total of more than 20,000 samples for testing, statistics and calculations developed. Although it is more suitable for the local conditions, the standardization of labor costs will take a lot of manpower, material and financial resources, which will take a long time and is not a nationwide data set. Therefore, it is inconvenient to formulate a unified national evaluation standard. The nutritional information in all parts of the country is comparable Poor sex is not conducive to the discovery of typical, sum up experience, to promote this work forward. As the use of “height standard weight” as a reflection of reality camp
