One hundred and twenty school girls in the age group of 13-15 years from four Government schools of Ludhiana city were selected for the study. On the basis of their family income they were divided into three experimental groups i.e. income group I (IgI), income group II (IgII) and income group III (IgIII). The results showed that the intake was low for all the foods. However, the consumption of fruits, milk and milk-products, sugar and jaggery, fats and oils by the subjects of IgII and IgIII was significantly higher (p < 0.05) than IgI. The mean daily intake of energy, protein, iron, calcium, vitamin A & vitamin C was inadequate while the intake of fibre was adequate by the subjects as compared to ICMR recommendations. There was no significant difference in energy, protein and iron intakes among the subjects of three groups. However, the fibre intake by the subjects of IgI was significantly higher (p < 0.05) than the subjects of IgIII, whereas the intake of calcium, vitamin A and ascorbic acid by the subjects of IgII & IgIII was significantly higher (p < 0.05) than those of IgI. The average body weights and heights of the subjects were normal. The haemoglobin (Hb) level of the subjects ranged from 8.5-12.5 g/dl with a mean value of 10.73 + 0.07 and reported that only 23 percent of the subjects had acceptable level.
从卢迪亚纳市四所政府学校中挑选了120名年龄在13至15岁之间的女学生进行这项研究。根据家庭收入，她们被分为三个实验组，即收入组I（IgI）、收入组II（IgII）和收入组III（IgIII）。结果显示，所有食物的摄入量都很低。然而，IgII组和IgIII组受试者的水果、牛奶及奶制品、糖和粗糖、脂肪和油类的消费量显著高于IgI组（p < 0.05）。与印度医学研究理事会（ICMR）的建议相比，受试者的能量、蛋白质、铁、钙、维生素A和维生素C的每日平均摄入量不足，而纤维摄入量充足。三组受试者的能量、蛋白质和铁摄入量没有显著差异。然而，IgI组受试者的纤维摄入量显著高于IgIII组（p < 0.05），而IgII组和IgIII组受试者的钙、维生素A和抗坏血酸摄入量显著高于IgI组（p < 0.05）。受试者的平均体重和身高正常。受试者的血红蛋白（Hb）水平在8.5 - 12.5 g/dl之间，平均值为10.73 ± 0.07，报告称只有23%的受试者血红蛋白水平达到可接受标准。
