目的了解高校贫困生血浆蛋白及血红蛋白水平,评价高校贫困生营养健康状况,为贫困生的管理和营养健康促进提供参考依据。方法分别选取某高校贫困生和非贫困生224名和112名,采用双缩脲法和溴甲酚绿法测血浆蛋白含量,氰化高铁比色法测血红蛋白质量体积分数,并进行比较。结果特困组学生的总蛋白和白蛋白均值分别为60.48g/L和40.18g/L,一般贫困组学生的血红蛋白均值为125.81g/L,特困组学生的血红蛋白均值为121.90g/L;与对照组比较,一般贫困组和特困组大学生的Hb均显著偏低(P值均<0.01)。结论贫困生的血浆蛋白和血红蛋白水平均明显偏低,贫血率明显偏高。
Objective To understand the plasma protein and hemoglobin level of poor students in colleges and universities and to evaluate the nutritional status of impoverished students in colleges and universities and to provide reference for the management of impoverished students and the promotion of nutrition and health. Methods A total of 224 and 112 poor and non-poor students were enrolled in this study. The plasma protein content was measured by the biuret method and the bromocresol green method, and the mass and volume fractions of hemoglobin were determined by cyanobacteria colorimetry. Results The average total protein and albumin of students in the destitute group were 60.48g / L and 40.18g / L, respectively. The average hemoglobin value of students in the impoverished group was 125.81g / L, and that of the destitute students was 121.90g / L. Compared with the control Compared with the control group, Hb in the general impoverished and destitute groups was significantly lower (P <0.01). Conclusion The plasma protein and hemoglobin of poor students are significantly lower, the anemia rate is obviously higher.
