To evaluate the risk of obesity in preschool children with prolonged screen time in Taiwan.
Using a nationwide survey with random sampling, we collected information on 8378 preschool children aged 2-6 years among 206 preschools in Taiwan from 2016 to 2019. Socioeconomic data, body mass index, and lifestyle of the preschool children and their caregivers were compared among the groups of preschool children who had moderate and prolonged daily screen time. We used multiple log-binomial regression models to calculate the adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) of obesity associated with prolonged screen time.
The prevalence of obesity in the preschool children was 13.1%, and the average screen time was 104.6 minutes. Children's age, sleep hours, outdoor play time, sugar intake, snack eating before dinner, sleep disturbance, and obesity, as well as caregiver's sex, age, education, screen time, exercise time and parent obesity were factors related to high screen time for preschool children. Compared with children with moderate screen time, children with prolonged screen time had a higher risk of obesity (PR, 1.45; 95% CI, 1.18-1.79). With a 60-minute increase in screen time, the risk of obesity increased, with an PR of 1.10 (95% CI, 1.03-1.17).
Preschool children with prolonged screen time had an increased risk of obesity in Taiwan. Interventions may be needed for this very susceptible population.
评估台湾学龄前儿童长时间使用电子设备的肥胖风险。
采用全国随机抽样调查，我们收集了2016年至2019年台湾206所幼儿园中8378名2至6岁学龄前儿童的信息。比较了中度和长时间每日使用电子设备的学龄前儿童组的社会经济数据、体重指数以及学龄前儿童及其照顾者的生活方式。我们使用多重对数二项回归模型来计算与长时间使用电子设备相关的肥胖调整患病率比（PRs）和95%置信区间（CIs）。
学龄前儿童的肥胖患病率为13.1%，平均使用电子设备时间为104.6分钟。儿童的年龄、睡眠时间、户外活动时间、糖摄入量、晚餐前吃零食、睡眠障碍和肥胖情况，以及照顾者的性别、年龄、教育程度、使用电子设备时间、锻炼时间和父母肥胖情况都是与学龄前儿童长时间使用电子设备相关的因素。与中度使用电子设备的儿童相比，长时间使用电子设备的儿童肥胖风险更高（PR，1.45；95%CI，1.18 - 1.79）。电子设备使用时间每增加60分钟，肥胖风险增加，PR为1.10（95%CI，1.03 - 1.17）。
在台湾，长时间使用电子设备的学龄前儿童肥胖风险增加。对于这一极易受影响的人群可能需要进行干预。
