Abstract:
Objective:To investigate the time and characteristics of screen exposure, to analyze the risk factors affecting screen exposure in children aged 3 years and younger, and to provide scientific basis for the intervention of screen exposure in children.Methods:The data were collected by convenience sampling from 317 children for routine examination aged 0-36 months who visited the Department of Child Healthcare, Children′s Hospital, Capital Institute of Pediatrics from December 2019 to December 2020. Self-designed questionnaires of the screen exposure were completed by the parents. The basic information, home nurture environment and screen exposure conditions were investigated. Children <18 months of age who used electronic devices and 18-36 months of age who spent more than 1 h/d on electronic devices were defined as with screen exposure. The differences between <18 and 18-36 months of age were compared by rank sum test. Chi-square test and multivariate Logistic regression were used to analyze the association between screen exposure and potential influential factors.Results:Among 317 children, 209 were boys and 108 girls, aged (28±10) months. There were 117 patients aged <18 months and 200 patients aged 18-36 months. Screen exposure time was 0.3 (0, 1.0) h/d and 1.2 (0.6, 2.0) h/d in children aged <18 months and aged 18-36 months, respectively ( Z=-6.770, P<0.01). The proportion of screen exposure was 25.6% (30/117) and 49.0% (98/200) in two age groups, respectively. Logistic regression analysis disclosed that not being the first child ( OR=3.81, 95% CI: 1.13-12.77, P=0.030), caregivers spending >1 h/d on electronic devices in front of their children ( OR=7.39, 95% CI: 2.24-24.46, P=0.001), caregivers believing that screen exposure can promote early childhood development ( OR=4.14, 95% CI: 1.26-13.52, P=0.019) were risk factors for children′s screen exposure in <18 months of age. Caregivers spending >1 h/d on electronic devices in front of their children ( OR=3.29, 95% CI: 1.78-6.08, P<0.01) was risk factor for children′s screen exposure in 18-36 months of age. Mothers with bachelor′s or higher degree ( OR=0.19, 95% CI: 0.05-0.66, P=0.009; OR=0.35, 95% CI: 0.19-0.66, P=0.001), no television in living room ( OR=0.11, 95% CI: 0.03-0.42, P=0.001; OR=0.45, 95% CI: 0.21-0.98, P=0.045) were protective factors for children′s screen exposure in children <18 months and 18-36 months of age. Conclusions:Excessive screen exposure is common among children aged 3 years and younger. The exposure time increases with age, and is affected by several factors.
