摘要:
目的 探讨睡眠期间卧室夜灯暴露与儿童情绪症状的关联,为后续开展有效预防和干预措施提供科学依据。 方法 对2021年12月在安徽省滁州市天长市2所小学招募的1 926名四至六年级学生开展问卷调查,收集一般人口统计学信息、夜灯和窗帘使用情况、情绪症状等资料。采用二元Logistic回归分析探讨夜灯使用情况与儿童情绪症状的相关性。 结果 儿童抑郁症状、广泛性焦虑症状、社交恐惧、强迫症状报告率分别为2.5%,2.6%,3.4%和2.5%。有12.6%的儿童睡眠期间经常开夜灯,22.0%的儿童睡眠期间不关窗帘。二元Logistic回归分析显示,经常开夜灯睡觉与儿童抑郁症状(OR=2.29,95%CI=1.04~5.03)、社交恐惧(OR=1.93,95%CI=1.02~3.64)、强迫症状(OR=3.44,95%CI=1.72~6.88)风险增加有关(P值均 < 0.05)。 结论 睡眠期间卧室夜灯暴露与儿童情绪症状报告率存在正向关联。应重视儿童睡眠期间卧室光环境,减轻夜间光暴露对儿童心理健康的不利影响。 Abstract:Objective To explore the association between exposure to bedroom night light during sleep and emotional symptoms in children and provide a scientific basis for subsequent effective prevention and intervention. Methods In December 2021, 1 926 students from grades 4 to 6 were recruited to conduct a student questionnaire survey in two primary schools in Tianchang of Chuzhou City, Anhui Province. The data, including general demographic information, use of night lights and curtains, emotional symptoms, and other information, was collected. Binary Logistic regression analysis was used to examine the correlation between night light use and children's emotional symptoms. Results The reporting rates of depression symptoms, generalized anxiety symptoms, social phobia, and obsessive-compulsive symptoms of the children were 2.5%, 2.6%, 3.4% and 2.5%, respectively. About 12.6% of children often sleep with a night light on, and 22.0% of children did not close the curtains. Binary Logistic regression analysis revealed that frequent sleep with night lights was associated with an increased risk of depression symptoms(OR=2.29, 95%CI=1.04-5.03), social phobia (OR=1.93, 95%CI=1.02-3.64) and obsessive-compulsive symptoms (OR=3.44, 95%CI=1.72-6.88) in children(P < 0.05). Conclusion There is a positive correlation between bedroom night light exposure during sleep and the detection rate of children's emotional symptoms. The attention should be paid to bedroom light environment of children during sleep to reduce the adverse effects of night light exposure on the mental health. -
