目的了解扬州市3~6岁学龄前儿童视屏时间现况以及可能导致每天视屏时间>2 h的影响因素,为制定相关干预措施提供依据。方法采用整群抽样的方法,选取扬州市城区7所幼儿园的2 531名在园儿童进行身高及体重的测量,并填写家长问卷,问卷调查主要包括父母健康状况、家庭信息、出生结局和视屏时间等内容,分析可能导致视屏时间>2 h的危险因素。结果扬州市城区学龄前儿童周一至周五平均每天视屏时间>2 h的比例分别为19.3%,39.3%和28.2%。以儿童3岁年龄组,儿童体重正常,父母年龄≥35岁,父母BMI为18.5~23.9 kg/m~2,父母本科及以上学历,独生子女分别作为参照组,进行二分类非条件Logistic回归分析表明,母亲现在BMI≥24 kg/m~2(OR=1.33)和本科以下学历(OR=2.15)是周一至周五视屏时间>2 h的危险因素;儿童4~6岁年龄组(OR值分别为1.53,1.88,1.95)、儿童肥胖(OR=1.34)、父亲年龄<35岁(OR=1.30)、母亲现在BMI≥24 kg/m~2(OR=1.32)、父母本科以下学历(OR值分别为1.37,1.90)以及非独生子女(OR=1.32)是周末视屏时间>2 h的危险因素。父亲年龄<35岁(OR=1.44)、母亲现在BMI≥24 kg/m~2(OR=1.43)和父母本科以下学历(OR值分别为1.27,2.10)是一周视屏时间>2 h的危险因素。结论儿童年龄、肥胖状况、父亲年龄、母亲现在BMI、父母学历、是否独生子女对学龄前儿童的视屏时间会产生影响。
