To estimate the prevalence of screen time (ST) and its associated effects, including emotional and behavioral changes, sleep disturbances, and physical activity levels, in children aged 2 to 5 years.
We conducted a cross-sectional study among 400 randomly selected children aged 2 to 5 years in Chandigarh, North India. We used a validated, pretested, semistructured digital-screen exposure and physical activity questionnaire; an abbreviated standard Child Sleep Habit Questionnaire; and a standard Preschool Child Behavior Checklist. We considered ST as excessive if it was more than 1 hour per day as per the American Academy of Pediatrics 2016 guidelines. IBM SPSS Statistics for Macintosh, version 25.0, was used to perform linear regression model analysis and stepwise binary multivariate logistic regression.
Approximately 59.5% of children (mean age 3.5 ± 0.9 years) had excessive ST. ST was higher on weekdays (58.5%) compared with the weekends (56.8%). Higher ST correlated positively with the mother's level of education (r = +0.219) and higher per capita family income (r = +0.227). Screen time was also positively correlated with attending daycare centers (adjusted odd's ratio [aOR] = 1.82, confidence interval [CI] = 1.18-2.81), caregivers ST of more than 2 hours (aOR = 1.68, CI = 1.12-2.56), and the absence of digital-media rules at home (aOR = 3.3, CI = 0.92-11.65). It was negatively correlated (i.e., protective) with lower mother's education (i.e., up to middle school) (aOR = 0.62, CI = 0.41-0.96) and watching educational digital-media content (aOR = 0.53, CI = 0.33-0.87).
We observed a high prevalence of excessive ST among children aged 2 to 5 years. Screen time was significantly associated with being in daycare centers, higher caregivers' ST, lower mothers' educational status, and educational digital content.
评估 2 至 5 岁儿童的屏幕时间(ST)流行率及其相关影响,包括情绪和行为变化、睡眠障碍和身体活动水平。
我们在印度北部昌迪加尔的 400 名随机选择的 2 至 5 岁儿童中进行了横断面研究。我们使用了经过验证、预测试、半结构化的数字屏幕暴露和身体活动问卷;简化的标准儿童睡眠习惯问卷;以及标准的学龄前儿童行为检查表。我们根据美国儿科学会 2016 年指南,将每天超过 1 小时的 ST 视为过度。使用 IBM SPSS Statistics for Macintosh,版本 25.0 进行线性回归模型分析和逐步二元多变量逻辑回归。
约 59.5%的儿童(平均年龄 3.5±0.9 岁)有过度的 ST。与周末相比,周内 ST 更高(58.5%比 56.8%)。较高的 ST 与母亲的教育程度呈正相关(r=+0.219)和更高的人均家庭收入(r=+0.227)。ST 也与上日托中心呈正相关(调整后的优势比[aOR]=1.82,置信区间[CI]=1.18-2.81)、照顾者的 ST 超过 2 小时(aOR=1.68,CI=1.12-2.56)和家中没有数字媒体规则(aOR=3.3,CI=0.92-11.65)。它与较低的母亲教育程度(即中学以下)呈负相关(即具有保护作用)(aOR=0.62,CI=0.41-0.96)和观看教育数字媒体内容(aOR=0.53,CI=0.33-0.87)。
我们观察到 2 至 5 岁儿童中过度 ST 的发生率很高。ST 与上日托中心、照顾者 ST 较高、母亲教育程度较低以及教育数字内容显著相关。
