外来务工子弟小学学生血红蛋白检测结果分析

目的:了解上海市高桥社区外来务工子弟小学学生血红蛋白值的变化特征,为制定预防贫血的策略提供参考依据。方法:以2019学年上海市高桥社区外来务工子弟小学1～4年级所有在校学生为研究对象,分别于2019年6月和2020年6月对其进行血红蛋白值检测。结果:共检测学生730人,其中男生417人(57.12%)、女生313人(42.88%)。男生两次血红蛋白均值分别为(128.95±13.72) g/L和(133.07±13.32) g/L,女生分别为(126.25±12.33) g/L和(128.87±12.84) g/L,男生两次血红蛋白均值均高于女生,差异有统计学意义(t值分别为8.19和4.33,P值均<0.05)。7岁组、8岁组、9岁组和10岁组学生第二次血红蛋白均值均高于第一次,差异均有统计学意义(t值分别为5.82、3.34、5.53和3.11,P值均<0.05)。肥胖组、超重组、正常组、轻度消瘦组、中重度消瘦组学生血红蛋白均值第二次均高于第一次,差异均有统计学意义(t值分别为3.50、2.94、7.08、2.26和2.20,P值均<0.05)。研究对象贫血发病率...

Analysis of Hemoglobin Monitoring Results of Primary School Students of Migrant Children

OBJECTIVE To understand the characteristics of hemoglobin in primary school students of migrant children in Gaoqiao community of Shanghai,and to provide reference for the development of anemia prevention and control strategies.METHODS Taking all the students from grade 1 to 4 of primary school for migrant children in the 2019 academic year in Gaoqiao community of Shanghai as the objects,the hemoglobin values of students were monitored in June 2019 and June 2020 and the monitoring results were analyzed.RESULTS A total of 730 students were tested,including 417 boys(57.12%)and 313 girls(42.88%).The mean hemoglobin was(128.95±13.72)g/L and(133.07±13.32)g/L for boys,(126.25±12.33)g/L and(128.87±12.84)g/L,respectively.The mean hemoglobin was higher than girls with statistical difference(t=8.19,4.33,P<0.05).The mean second hemoglobin in the 7-year-old,8-year-old,9-year-old and 10-year-old groups were greater than the first and the differences were statistically significant(t=5.82,3.34,5.53 and 3.11,P<0.05).The mean values of hemoglobin in the second time between obese,super recombination,normal,mild and moderate and severe wasting were greater than the first and the differences were statistically significant(t=3.50,2.94,7.08,2.26 and 2.20,P<0.05).The incidence of anemia,recovery rate,and population persistence rate of the study subjects were 13.32%,61.48%,and 6.44%,respectively.The incidence of anemia in girls and population persistence were higher than boys(χ²=4.45,4.35,P<0.05)and the differences were statistically significant.Comparison of anemia incidence,recovery rate,and persistence rate of the population in each age group,anemia incidence(χ²=19.91,7.62 and 12.78,P<0.05),the differences were statistically significant.Comparison of anemia incidence,recovery rate and persistence of population among students with different nutritional status(χ²=16.65,5.11 and 37.26,P<0.05),the differences were statistically significant.CONCLUSION Anemia monitoring of primary school students from migrant workers should be continuously strengthened,and the intervention focuses on girls,lower grades,wasting and persistent anemia.
