Global debates among researchers, clinicians, policy makers, and parents on the benefits vs consequences of children’s screen time exposure are ubiquitous. Research suggests that excessive screen time is likely consequential for early child development and health.^1,2 Accordingly, the World Health Organization and various pediatric societies have issued guidelines on screen time, suggesting that preschoolers receive no more than 1 hour of high-quality programming daily.³ To inform policy and educational initiatives, the objectives of this study were 2-fold: (1) determine the prevalence of children ages 2 and 3 years meeting vs exceeding screen time guidelines and (2) determine the strongest individual and family-level factors associated with failing to meet these guidelines.

在研究人员，临床医生，政策制定者和父母之间，关于儿童放映时间的益处与后果的全球辩论无处不在。研究表明，过多的放映时间可能对早期儿童发育和健康造成影响。^{1 ，2}因此，世界卫生组织和各种儿科学会已发出在屏幕上时的准则，这表明学龄前儿童接受不超过1小时的高品质的日常节目。³ 为了提供政策和教育措施，本研究的目标是2倍：（1）确定满足2岁和3岁年龄段儿童的患病率与超出筛查时间准则的比例；（2）确定与个人和家庭相关的最强因素不符合这些准则。
