目的 研究婴幼儿期视屏接触时间与多动指数的关联,为探索低龄儿童视屏会否增加多动行为提供线索。方法 采用回顾性研究于2018年9月对深圳市龙华区22 586名入组儿童的父母进行调查,用自编问卷收集一般人口学变量、视屏接触时间,采用Conners父母用症状问卷调查多动指数,分析婴幼儿期视屏接触时间与多动指数的关联。结果 儿童多动指数异常率为1.7%。婴幼儿期电视和新一代电子产品的视屏接触时间均随年龄增长而增长。＜1、1～<2、2～3岁年龄段电视和新一代电子产品的视屏接触时间均与多动指数异常有相关性(P＜0.05),且低年龄组视屏增加多动指数异常的风险比高年龄组大。0～3岁每日视屏接触时间越长,多动指数异常的风险越大,≥1 h/d、＜1 h/d组与无视屏组相比,电视的OR值(95%CI)分别为5.36(3.27～8.78)、2.06(1.24～3.42),新一代电子产品的OR值(95%CI)分别为5.94(3.79～9.30)、2.25(1.48～3.41)。0～3岁单次视屏接触时间(min/次)越长多动指数异常的风险越大,≥120、60～<120、30～<60、15～<30与＜15相比,OR值(95%CI)分别为3.13(1.33～7.37)、2.81(1.83～4.31)、1.46(1.05～2.04)、1.23(0.92～1.64)。结论 婴幼儿期过早接触视屏、每日视屏总时间过多、单次视屏接触时间过长均可能与多动指数异常相关,建议2岁内的婴幼儿不宜接触电子屏幕,2～3岁控制每天视屏总时间少于30 min。
Abstract
Objective To investigate the correlation between screen time and hyperactivity index in infants,so as to provide clues for the impact of screen time on hyperactivity behavior in young children.Methods Totally 22 586 children in Longhua district of Shenzhen were enrolled in this study,and their parents were surveyed in September 2018.The general demographic variables and screen time were collected by a self-designed questionnaire.The hyperactivity index was investigated by Conners Parental Symptom Questionnaire(PSQ) to analyze the correlation between screen time and hyperactivity index in infants.Results The abnormal rate of hyperkinetic index was 1.7%.Screen time for TV sets and new electronic products in infants increased with age,which was significantly related to abnormal results of hyperactivity index in children under 1 year old,1-to 2-year-old children,and 2-to 3-year-old children,and the risk was higher in younger children.The longer the daily screen time in children under 3 years old,the higher the risk of abnormal hyperactivity index would be.Compared with the non-screen group,TV screen time≥1 h/d (OR=5.36,95%CI:3.27-8.78) and ＜1 h/d (OR=2.06,95%CI:1.24-3.42) were risk factors for abnormal hyperactivity index,and the corresponding OR value in new electronic products was 5.94(95%CI:3.79-9.30) and 2.25(95%CI:1.48-3.41),respectively.The longer the single screen time,the higher the risk of abnormal hyperactivity index would be.Compared with screen time＜15 min,the OR value (95%CI) for abnormal hyperactivity index in single screen time ≥120,60-120,30-60,15-30 min was 3.13 (1.33-7.37),2.81 (1.83-4.31),1.46 (1.05-2.04),and 1.23 (0.92-1.64),respectively.Conclusions Early exposure to screen and excessive screen time in infant stage may be correlated with abnormal hyperactivity index.It is recommended that children under 2 years old should not screen every day,and the total screen time should be controlled less than 0.5 hour in 2-to 3-year-old children.
