目的了解石家庄市城市中小学生营养状况、视力不良现况,为制定防控措施提供科学的理论依据。方法按照《学生健康检查技术规范》的要求,对石家庄市12所学校22 707名在校学生进行了身高、体重的测量及视力检查。结果石家庄市城区中小学生营养不良率为8.1%;肥胖率为19.7%,男生营养不良(χ2=76.9,P<0.005)、肥胖率(χ2=18.34,P<0.005)均高于女生,差异有统计学意义;视力不良检出率55.4%,女生视力不良检出率高于男生,差异有统计学意义(χ2=114.65,P<0.005),视力不良检出率随年级增长而增加(χ2趋势=3247,P<0.005)。结论石家庄市城区学生肥胖、视力不良情况不容乐观,应采取有效的预防和控制措施。
Objective To understand the nutritional status and poor eyesight status of primary and secondary school students in Shijiazhuang and to provide a scientific basis for the development of prevention and control measures. Methods According to the requirements of “Technical Specifications for Student Health Checkup”, 22 707 school-aged students from 12 schools in Shijiazhuang were surveyed for height and weight, and visual acuity. Results The incidence of malnutrition among urban primary and secondary school students in Shijiazhuang was 8.1%, obesity rate was 19.7%, malnutrition in boys (χ2 = 76.9, P <0.005) and obesity rate (χ2 = 18.34, P <0.005) (Χ2 = 114.65, P <0.005). The detection rate of poor eyesight increased with the increase of grade (χ2 trend), the incidence of poor eyesight was significantly higher than that of boys = 3247, P <0.005). Conclusion Students in urban area of Shijiazhuang City are not optimistic about obesity and poor visual acuity. Effective prevention and control measures should be taken.
