目的了解珠海市小学生营养不良的分布状况,以及小学生营养不良与Hb和血清Zn、Fe、PA检出率的关系。方法按照中国学者在世界卫生组织推荐的“儿童生长标准”(简易版),进行营养不良筛查,营养不良组与正常对照组进行Hb,血清Zn、Fe、PA检测,并将两组的检出率进行比较。结果农村小学生生长迟缓+消瘦检出率为10.16%,城区为6.92%,差异有统计学意义(χ2=10.51,P<0.01)。生长迟缓+消瘦组缺Zn检出率,PA阳性率分别为24.25%,22.76%,均高于正常对照组,差异有统计学意义(χ2=9.07,23.12,P<0.01)。结论珠海市小学生营养保健工作应把重点放在农村,生长迟缓小学生健康状况甚忧,应采取干预措施赶上正常水平。
Objective To understand the distribution of malnutrition among primary school students in Zhuhai and the relationship between malnutrition among primary school students and the detection rate of Hb and serum Zn, Fe and PA. Methods Hb, serum Zn, Fe, PA were detected by malnutrition screening, malnutrition group and normal control group according to the “Chinese Children’s Growth Standards” recommended by Chinese scholars in the World Health Organization. Two groups The detection rate was compared. Results The rate of growth retardation and emaciation was 10.16% in rural primary school students and 6.92% in urban areas (χ2 = 10.51, P <0.01). Growth retardation + weight loss group lack of detection rate of Zn, PA positive rates were 24.25%, 22.76%, were higher than the normal control group, the difference was statistically significant (χ2 = 9.07,23.12, P <0.01). Conclusion The nutrition and health care for primary school students in Zhuhai should focus on the rural areas. The students with stunting growth have poor health status. Interventions should be taken to catch up with the normal level.
