摘要： 目的 了解初中生近视状况及家庭有关的影响因素,为有效防控近视提供科学参考。方法 2016年4月分层整群随机抽取淄博市某区初中生共1 036名,进行屈光度检查,并对学生家长进行问卷调查。结果 2016年淄博市某区初中一、二年级学生近视检出率为73.24%,轻、中、高度近视检出率依次为47.77%、22.79%、2.68%。不同年级、不同性别的学生近视检出率差异均有统计学意义(P均<0.05)。婴儿时足月出生、在家坐姿正确、上体育类培训班以及父母每半年带儿童检查一次视力是学生近视的保护因素(P均<0.05);而在家习惯躺着看书是学生近视的危险因素(P<0.05)。结论 淄博市初中生近视水平较高。家长与学校共同培养学生良好的用眼和生活习惯是防治近视的关键。
