中文摘要: 目的 调查闵行区4~6岁学龄前儿童视力低常检出率情况以及相关影响因素。方法 随机抽取闵行区在读幼儿园学生（n=6 179）进行视力检查。调查问卷了解近视相关因素，包括父母近视情况、工作日/休息日读写时间、户外活动时间以及用眼习惯等。结果 视力低常检出率为12.06%。不同居住地、早产情况、遗传史和父母近视度数，视力低常检出率的差异有统计学意义；工作日玩耍和户外运动时间与视力低常的检出率呈负相关(P﹤0.05,OR=0.998)。结论 学龄前儿童应积极开展视力筛查，遗传因素与近距离看电视是学龄前儿童视力低常的危险因素，应提倡多参加户外体育运动，合理用眼，做到早发现，早矫正，合理预防。
