目的 探索综合干预措施对小学生视力不良的影响。方法 选择鹤壁市城区2 所条件相似小学校所有学生为研究对象,对1所学校学生施行视力不良防控综合干预,另1所学校学生接受常规防控措施,一年后,比较两个学校学生视力不良发生情况。结果 干预后,干预组学生视力不良检出率为25.31%,对照组学生视力不良检出率为29.48%,差异有统计学意义(χ²=6.840,P=0.011);两校学生视力分布情况比较,干预组学生视力在正常等级的比例较高,对照组学生的视力在中、重度视力不良等级的比例较高,差异有统计学意义(χ²=14.011,P=0.003)。结论 小学阶段开展视力不良防控综合干预,对改善学生视力不良作用明显。

Objective To explore the effect of comprehensive intervention measures on poor eyesight of primary school students. Methods All the students in two primary schools with similar conditions in Hebi City were selected as the research objects.The students in one school were given comprehensive prevention and control intervention,and the students in the other school were given routine prevention and control measures.One year later,the incidence of poor eyesight of the students in the two schools was compared. Results After the intervention,the detection rate of poor eyesight was 25.31% in the intervention group and 29.48% in the control group,the difference was statistically significant(χ²=6.840,P=0.011).The results showed that more students in the intervention group were in the normal level,while more students in the control group were in the moderate and severe poor eyesight level,the difference was statistically significant(χ²=14.011,P=0.003). Conclusion The comprehensive intervention on the prevention and control of poor eyesight in primary school plays an obvious role in improving students' poor eyesight.
