宁波市中小学生视力不良状况调查

为了解宁波市中小学生视力不良的发生率,以2010年浙江省学生体质调研数据为基础,对宁波市3085名中小学生视力进行了调查研究.结果表明:宁波市中小学生视力不良检出率为69.9%,其中男生为69.0%,女生为70.8%;城市学生视力不良检出率为71.2%,乡村学生为68.6%,可见城市学生的视力不良检出率高于乡村学生,并存在统计学意义(P<0.05);但这种城乡差异和2005年学生体质调研中得到的数据相比较,呈现弱化趋势;视力不良的检出率已不再有性别差异;在低年龄段和轻度视力不良程度内,视力不良检出率随年龄的增长突增期提前,中学学段是学生视力不良重灾区,同年龄段视力不良的检出率远超过2005年调查数据.
