经过对281名城市小学生追踪观察发现,随着蛔虫感染率的下降城市小学生营养不良率有逐年下降的趋势,1980年～1985年小学生营养不良率分别为42.35％、41.28％、23.49％、40.21％、39.64％、38.84％。1986年又扩大样本数调查发现城乡小学生营养不良率为35.90％(382/1064)。虽与全国水平差不多,但仍较严重。于是我们在1986年10月又抽样调查了中小学生的营养状况。采用氰化高铁法,检验了城市中小学生的血红蛋白,不足12g％者占75.0％,血清总蛋白不足6g％者占6.9％;维生素B_2不足400微克者占10.0％(小生学缺的较少);维生素C不足5mg％者占40％,血清钙不足9％者占13.3％。
After 281 city primary school students follow-up observation found that as the ascaris infection rate of urban primary school students malnutrition rate decreased year by year, from 1980 to 1985 primary school students malnutrition rates were 42.35%, 41.28%, 23.49%, 40.21% , 39.64%, 38.84%. In 1986, it expanded the number of samples and found that the malnutrition rate among urban and rural primary school students was 35.90% (382/1064). Although similar to the national level, but still more serious. So we conducted a sample survey of the nutritional status of primary and secondary school students in October 1986. Using cyanidation of high-speed rail, primary and secondary school students in urban hemoglobin test, less than 12g% accounted for 75.0%, serum total protein less than 6g% accounted for 6.9%; vitamin B_2 less than 400 micrograms 10.0% (less niche missing) ; Vitamin C less than 5mg% accounted for 40%, serum calcium less than 9% accounted for 13.3%.
