【摘要】 目的了解东乡族学生视力状况,为东乡族学生视力不良的防治工作提供依据。方法按照2010年全国学生体质健康调研细则要求,对2 484名东乡族7～18岁学生先用标准对数视力表测量学生裸眼视力,再对视力不良者使用串镜检查,判定屈光不正性质;抽取2010年甘肃省汉族7～18岁学生视力测试资料进行比较。结果东乡族学生视力不良率为24.94%,其中男生为23.09%,女生为26.71%,差异无统计学意义(u=1.80,P>0.05);小学生、中学生的视力不良检出率分别为9.48%和40.96%,差异有统计学意义(u=24.92,P<0.01);东乡族学生与汉族学生视力不良率分别为24.92%和63.20%,差异有统计学意义(u=36.85,P<0.01)。东乡族学生视力不良主要是近视,占99.12%。结论东乡族学生视力较好,但视力不良率仍随年龄增长呈上升态势。防治东乡族学生视力不良需家庭、学校和社会共同参与,从早期抓起。更多还原
