摘要
目的:调查佳木斯市某校小学生和中学生的近视现状,对近视学生通过合理膳食、加强体育运动和佩戴蓝光防护眼镜的措施进行综合干预,探讨综合干预方案对学生视力的影响情况,为今后近视防控工作的实施提供一定的科学依据。方法:采取普查的方法,对小学生212人,初中生146人,进行眼科检查,并进行干预。干预时间为9个月(2019年1月1日—2019年10月10日),分析并比较干预前和干预后学生视力的变化。统计分析使用R 4.0.2软件,非正态资料采用秩和检验,计数资料采用卡方检验,P<0.05为差异有统计学意义。结果:共有358名学生参与本次调查,其中小学生212人,初中生146人;干预前视力正常127人,异常231人;干预后视力正常176人,异常182人,干预前后差异有统计学意义,视力好转49人,转好率21.21%。干预前与干预后对比,联合光度变化和屈光度变化,差异有统计学意义(P<0.001),好转人数男生和女生相比,差异无统计学意义(P>0.05),干预措施对屈光不正有效,无性别差异。干预前和干预后裸眼视力变化具有统计学差异(P<0.001),综合干预后学生裸眼视力有所提高。结论:通过改变饮食习惯、合理膳食,加强体育运动,蓝光眼镜防护的综合干预措施对小学生和中学生近视的防控有一定的效果。
