Abstract:
OBJECTIVE: This pilot study aimed to describe children\'s social contact patterns and to analyze factors related to their social contacts.
METHODS: The participants were 30 children aged ≥13 months to <7 years, whose teachers at childcare centers and parents at home were asked to maintain diaries of their social contacts prospectively for 24 hours. Data were collected from November 30, 2018, to January 7, 2019.
RESULTS: The 30 participating children were in contact with 363 persons in a 24-hours period (mean, 12.1±9.1). The number of contacts showed significant relationships with day of the week (p<.001), number of family members/cohabitants (p=.015), area of residence (p=.003), and type of housing (p=.002). A multiple regression model showed significantly higher numbers of contacts on weekdays (B=10.64, p=.010). Physical versus non-physical types of contact showed significant differences in terms of duration, location, and frequency (p<.001). The duration of contacts showed significant relationships with their location and frequency (p<.001), while the frequency of contacts was significantly related to their location (p<.001).
CONCLUSIONS: This is the first survey describing the characteristics of Korean preschool children\'s social contacts. Further large-scale social contact studies of children should be conducted.
摘要:
目的:这项初步研究旨在描述儿童的社会接触模式并分析与其社会接触相关的因素。
方法:参与者是30名年龄≥13个月至<7岁的儿童,他们在托儿所的老师和在家的父母被要求在24小时内前瞻性地保存他们的社会接触日记。数据收集时间为2018年11月30日至2019年1月7日。
结果:30名参与儿童在24小时内与363人接触(平均,12.1±9.1)。接触人数与星期几显示出显著的关系(p<.001),家庭成员/同居者数量(p=.015),居住面积(p=0.003),和住房类型(p=0.002)。多元回归模型显示,工作日的接触人数显着增加(B=10.64,p=.010)。物理与非物理接触类型在持续时间方面表现出显著差异,location,和频率(p<.001)。接触的持续时间与它们的位置和频率显著相关(p<.001),而接触频率与他们的位置显著相关(p<.001)。
结论:这是首次描述韩国学龄前儿童社会交往特点的调查。应该对儿童进行进一步的大规模社会接触研究。
