【摘要】：目的:探讨学龄期儿童贫血与体格生长的关系。方法:在重庆市九龙坡区采用多阶段分层整群随机抽样的方法,对5所全日制公立小学的6 260名学龄儿童进行体格测量及血生化指标检查。统计分析贫血组及非贫血组间常用体格生长指标(体质量、身高)和与贫血相关的血常规指标,如红细胞平均容积(mean corpuscular volume,MCV)、红细胞平均血红蛋白(mean corpuscular hemoglobin,MCH)、红细胞平均血红蛋白浓度(mean corpuscular hemoglobin concentration,MCHC)和红细胞分布宽度(red blood cell distribution width,RDW)的差异及相关性。结果:4 730例有效样本中,共检出1 140例贫血儿童,贫血的总检出率为24.1%,女童贫血的检出率显著高于男童(男童检出率为22.6%,女童检出率为25.7%,χ2=6.100,P=0.010)。各年龄组(6岁~、7岁~、8岁~、9岁~、10岁~、11岁~、12岁~)贫血检出率分别为29.1%、29.1%、27.6%、23.7%、20.9%、17.4%、10.5%。不同年龄组间贫血检出率存在显著差异(χ2=75.800,P=0.000)。贫血组与非贫血组间的体格生长指标、血常规指标均存在显著性差异(P0.05)。贫血对儿童的体质量及身高均具有显著影响(分别为F=124.400,P=0.000;F=93.650,P=0.000)。血红蛋白(Hb)浓度与体质量、身高、体质指数(body mass index,BMI)、MCV、MCH、MCHC均具有显著相关性(相关系数分别为0.233、0.221、0.174、0.277、0.427、0.319,P值均为0.000)。结论:重庆市九龙坡区学龄儿童贫血的发生率较高;贫血的发生与年龄、性别、体质量和身高均存在相关关系;贫血对学龄期儿童的体质量及身高均具有显著影响。提示重庆市九龙坡区学龄儿童贫血情况需高度重视,应该加强对该类儿童家长及儿童本身的营养宣教,提高其对营养的关注度,合理膳食。
[Abstract]:Objective: To investigate the relationship between anemia and physical growth in school-age children. Methods: a multi stage stratified cluster random sampling method was used in the Jiulongpo District of Chongqing, and 6260 school-age children in 5 full-time public primary schools were measured and the blood biochemical indexes were examined. Body mass, height) and anemia related blood routine indicators such as the average volume of mean corpuscular volume (MCV), the average hemoglobin (mean corpuscular hemoglobin, MCH) of the red cell, the average hemoglobin concentration of the red cell (mean corpuscular hemoglobin concentration,) and the red cell distribution width. Ion width, RDW) differences and correlation. Results: in 4730 cases of effective samples, 1140 cases of anemia children were detected, the total detection rate of anemia was 24.1%, the prevalence rate of anemia in girls was significantly higher than that of boys (boys were 22.6%, girls were 25.7%, 7 years ~, 8 years ~, 9 years old ~ 10 years, 11 years, 12 years old ~) poor. The detectable rates of blood were 29.1%, 29.1%, 27.6%, 23.7%, 20.9%, 17.4%, and there were significant differences in the incidence of anemia among different age groups (x 2=75.800, P=0.000). There were significant differences in the physical growth indices between the anemia group and the non anemia group (P0.05). Anemia has significant influence on the body mass and height of children (F, respectively, F =124.400, P=0.000; F=93.650, P=0.000). The concentration of hemoglobin (Hb) and body mass, height, body mass index (body mass index, BMI), MCV, MCH, and MCHC all have significant correlation (the correlation coefficient is 0). Conclusion: the incidence of anemia in school age children in Chongqing Jiulongpo area is higher; anemia is the hair. There is a correlation between life and age, sex, body quality and height. Anemia has a significant influence on the body quality and height of school-age children. It is suggested that the anemia of school age children in Chongqing Jiulongpo area should be highly valued. The nutrition education of parents and children of this kind of children should be strengthened so as to improve their attention to nutrition and reasonable diet. Food.
