摘　　要：目的了解学龄儿童视力和营养状况，并探讨其关系，为儿童保健和疾病预防提供依据。方法选取2012年9月某小学学龄儿童2393人为研究对象，分为低、中、高年级3组，测量其身高、体重、视力及营养状况，对结果进行统计分析。结果学龄儿童视力为5．00（4．50，5．10），男女生视力均随年龄增长而下降（X^2=85．003，P〈0．05）、高年级男高于女（左眼Z=-2．024，P〈0．05；右眼Z=-2．268，P〈0．05）；学龄儿童视力不良率为45．22％，男女儿童视力不良率均随年龄增长而增高（男：X^2=43．036，P〈0．05；女：X^2=75．886，P〈0．05）；高年级女生视力不良率为63．93％，高于男生的55．39％（X^2=5．921，P〈0．05）。，营养不良儿童视力不良率高年级组女生大于男生组（X^2=5．240，P〈0．05），正常体重儿童视力不良率高年级组女生组大于男生组（X^2=6．056，P〈0．05）；视力不良率在营养不良、较低体重、正常体重、超重及肥胖营养状况下均无统计学意义（均P〉0．05）。视力状况与营养状况无相关性（r=0．021，P=0．313），与性别、年龄、身高具有相关性（r值分别为-0．040、-0．241和-0．222，均P〈0．05）。结论学龄儿童视力状况与营养状况无相关性，学龄儿童视力状况不容乐观，应加强预防和干预。Objective To explore the relation between vision and nutrition in school age children, so as to provide evidence for prevention and heahhcare. Methods In September 2012 2 393 school age children in a primary school were selected and grouped into primary group, junior group and senior group. Their height, weight, vision and nutrition were measured for analysis. Results School age children＇ s vision was 5. 00 （4.55,5.10）, and it declined with age both in boys and girls （X^2 = 85. 003, P 〈 0.05）. Boy＇ s vision was better than girl＇ s in senior group （left z = - 2. 024, P 〈 0. 05 ; right z = - 2. 268, P 〈 0.05 ）. Rate of poor eyesight was 45.22%, and it increased with age （malex2 =43. 036, P 〈 0.05 ; female X^2 = 75. 886, P 〈 0.05 ）. The rate of poor eyesight of girls （63.93%） was higher than boys （55.39%） in senior group （X^2 =5. 921 ,P 〈0.05）. The rate of poor eyesight of malnutrition children was higher in girls than in boys in senior group （X^2 = 5. 240, P 〈 0.05 ）, and that of children with normal weight was also higher in girls （X^2 = 6. 056, P 〈 0.05 ）. There were no differences in malnutrition, low weight, normal weight, overweight and obesity （ all P 〉 0.05 ）. Vision was not correlated with nutrition （ r = 0. 021, P = 0.313 ）, but correlated with gender, age and height （ r value was - 0.040, - 0.241 and - 0. 222, respectively, all P 〈 0.05）. Conclusion There is no correlation between vision and nutrition in school age children. More attention should be paid to poor eyesight in school age children.
