【摘要】 对贵阳地区170名汉族、苗族、布依族孕妇的孕中、后期进行营养调查。结果表明,该区孕中、后期孕妇膳食中热量的摄入基本达到孕妇供给量标准。热量来源分配基本合理。孕妇膳食中存在的主要问题是蛋白质摄入量不足,优质蛋白占总蛋白之比,除汉族达到30％以上外,苗族、布依族均在25％以下。钙、B₂。摄入量三组均明显低于孕妇供给量标准。汉族在孕后期,视黄醇摄入量仅达到供给量的73％。孕妇贫血患病率在26.92～50.00％。汉族、苗族、布依族三组新生儿出生体重、身长均无显著性差异（p>0.05）,发育指标均属中等水平。更多还原

【Abstract】 A nutrition survey of 170 pregnant women of the Han, Miao and Buyi nationality in the middle and late pregnancy was conducted in 1984. The survey included dietary survey, physical and obstetrical examination, biochemical analysis and measurement of weight and height of the newborns of the women studied. The results showed that their calorie intake was substantially suficient to the RDA but the protein intake was inadequate. The proportion of high quality protein was more than 30% of total protein intake for the Han, but less than 25% for the other two nationalities. The calcium and vitamin B2 intakes were much lower than RDA for all the women studied. The retinol intake was only about 73% of RDA for the Han in the late pregnancy. The incidence of nutritional anaemia was 26.92-50.00% among the 170 pregnant women. The weight-height of the newborns has no significant difference among three nationalities and all indices of physical development status were in medium rank on an average.更多还原
