【摘要】：目的了解绍兴市7~15岁中小学生近视状况,为制定干预措施提供科学依据。方法采用分层整群抽样方法,选取绍兴市4所小学和4所中学共2 911名学生采用室内灯箱式标准对数视力表测量双眼视力,裸眼视力≤4.9为视力不良;然后用1%阿托品进行散瞳检影验光,屈光范围0.5 D为近视进行视力检测。使用统计方法主要有χ2检验、t检验、方差分析等。结果小学生近视检出率(25.1%)低于初中生(72.8%)(χ2=592.626,P0.01);小学生近视平均度数为(213.88±105.98),中学生近视平均度数为(305.44±165.23),差异有统计学意义(t=-8.057,P0.01)。近视检出率和近视度数随着年级递增而升高(χ2/F值分别为667.195,10.753,P值均0.01),城市学生近视率高于农村学生(χ2=42.224,P0.01),重点学校学生近视率高于一般学校(χ2=6.224,P0.05)。结论绍兴市中小学生近视状况不容乐观。应加大近视高发态势的干预力度,培养健康和科学的用眼习惯。
