Abstract

BACKGROUND

Excessive digital screen exposure (≥1 hour per day) is associated with limited growth and development in children.

OBJECTIVE

This study aims to develop and assess a multicomponent intervention program's effectiveness in reducing excessive screen time among children aged 2-5 years.

METHODS

A theory-based multicomponent intervention known as Program to Lower Unwanted Media Screens (PLUMS) at the household level has been developed. It is based on the social cognitive theory for children and self-determination theory for caregivers. After pretesting, a randomized control trial will be conducted to assess this intervention's effectiveness among healthy children aged 2-5 (±3 months) years and their primary caregivers who have at least one digital media gadget at home in zone three of Chandigarh (population of 2,730,035). A sample size of 428 children is estimated per arm. PLUMS includes disseminating specific information, education, communication in the form of videos and posters to the primary caregivers, and conducting motivational interviewing as and when needed. Children will be provided suggestions for playful activities as alternatives to digital media gadgets. The primary outcome is the mean change in the duration of screen time, and secondary outcomes are sleep duration and patterns, emotional-behavioral problems, and level of physical activity of the children. Per-protocol and intention-to-treat analyses will be conducted using SPSS for Macintosh, Version 25.0.

RESULTS

The intervention package will be disseminated once a week for 8 weeks to the participants via the caregivers' preferred means of communication. The endline assessment will be done immediately postintervention and after the 6 months of follow-up. The Institute's ethics committee, Postgraduate Institute of Medical Education and Research, Chandigarh, India, has approved this study (INT/IEC/2019/000711). The Indian Council of Medical Research, New Delhi (3/1/3/Next-100/JRF-2015/HRD), and PGIMER, Chandigarh (71/2-Edu-16/92, Dated 08/01/2018) funded this study.

CONCLUSIONS

PLUMS might be effective in reducing excessive screen time among children aged 2-5 years in a North Indian Union Territory.

摘要

背景

儿童每天数字屏幕暴露时间过长（≥1小时）与生长发育受限有关。

目的

本研究旨在开发并评估一项多成分干预计划在减少2至5岁儿童过度屏幕使用时间方面的有效性。

方法

已开发出一种基于理论的家庭层面多成分干预措施，称为减少不必要媒体屏幕计划（PLUMS）。它基于儿童的社会认知理论和照顾者的自我决定理论。经过预测试后，将进行一项随机对照试验，以评估该干预措施在印度昌迪加尔三区（人口2730035）家中至少拥有一件数字媒体设备的2至5岁（±3个月）健康儿童及其主要照顾者中的有效性。预计每组样本量为428名儿童。PLUMS包括向主要照顾者传播特定信息、教育内容，以视频和海报形式进行沟通，并在需要时进行动机访谈。将为儿童提供有趣活动的建议，作为数字媒体设备的替代选择。主要结局是屏幕使用时间的平均变化，次要结局是睡眠时间和模式、情绪行为问题以及儿童的身体活动水平。将使用适用于Macintosh的SPSS 25.0版进行符合方案分析和意向性分析。

结果

干预方案将通过照顾者偏爱的沟通方式，每周向参与者传播一次，持续8周。干预结束后立即进行终末评估，并在随访6个月后进行。印度昌迪加尔医学教育与研究研究生院的机构伦理委员会已批准本研究（INT/IEC/2019/000711）。本研究由新德里印度医学研究理事会（3/1/3/Next-100/JRF-2015/HRD）和昌迪加尔PGIMER（71/2-Edu-16/92，日期为2018年1月8日）资助。
