to assess the level of anxiety and characterize the quality of sleep in children living in radioactively con-taminated areas in comparison with children who were not affected by the Chornobyl-affected contingents that werequarantined in connection with the COVID-19 pandemic.
The indicators of the level of anxiety were studied using the scale of self-assessment of thelevel of anxiety Ch.D. Spielberger, sleep quality was assessed using a standardized questionnaire for self-completionof PSQI and 137Cs content was measured in children. The main group consisted of 96 children who were quarantineddue to the COVID-19 pandemic and permanently lived in radioactively contaminated areas of Zhytomyr and Rivneregions with a soil contamination density of 137Cs from 18 kBq/m2 to 235 kBq/m2. The age of children ranged from10 to 17 years. Among them were 33 boys and 63 girls. The comparison group consisted of 52 children of similar age,including 26 boys and 26 girls. These children lived permanently in Kyiv and were not victims of the Chornobyl dis-aster.
It was found that children who were quarantined for COVID-19 (both residents of radioactively contami-nated areas and children who do not belong to the contingents affected by the Chornobyl disaster) had an increasedlevel of reactive (RA) and personal anxiety (PA). The comparative analysis showed that children of the same sex ofthe main group and the comparison group did not differ in terms of PA and RA. At the same time, studies have shownthat girls, both in the main group and in the comparison group, were characterized by higher levels of PA and RAthan boys. It was determined that poor sleep quality was common in both children living in radioactively contami-nated areas (42.71 %) and children in the comparison group (42.44 %). Among the sleep disorders in children ofboth observation groups, «day dysfunction» was most often detected.
There was a direct correlation between the overall PSQI score and the level of reactive, personal anx-iety and the overall PSQI score. Using regression analysis, the presence of a linear association of the level of incorporated 137Cs (Bq) with the indicator of personal anxiety of children living in radioactively contaminated territory (b = -0.716, p < 0.001) was proved.
评估生活在放射性污染地区的儿童的焦虑水平，并描述他们的睡眠质量，与因 COVID-19 疫情而被隔离的、未受切尔诺贝利影响的儿童进行对比。
采用 Ch.D. Spielberger 焦虑自评量表评估焦虑水平指标，使用标准化问卷自评 PSQI 评估睡眠质量，测量儿童体内 137Cs 含量。主要组由 96 名儿童组成，他们因 COVID-19 疫情而被隔离，长期生活在基辅、日托米尔和里夫尼地区的放射性污染区，土壤 137Cs 污染密度为 18 kBq/m2 至 235 kBq/m2。儿童年龄为 10 至 17 岁，其中 33 名男孩，63 名女孩。对照组由 52 名年龄相仿的儿童组成，其中 26 名男孩，26 名女孩，他们长期生活在基辅，并非切尔诺贝利灾难的受害者。
研究发现，因 COVID-19 而被隔离的儿童（包括生活在放射性污染区的儿童和未受切尔诺贝利影响的儿童）的反应性（RA）和个人焦虑（PA）水平均有所升高。对比分析表明，主要组和对照组的同性别儿童在 PA 和 RA 方面没有差异。同时，研究表明，主要组和对照组的女孩的 PA 和 RA 水平均高于男孩。两组儿童的睡眠质量均较差（主要组 42.71%，对照组 42.44%）。在两组观察儿童的睡眠障碍中，最常发现“日间功能障碍”。
整体 PSQI 评分与反应性、个人焦虑水平以及整体 PSQI 评分之间存在直接相关性。通过回归分析，证明了生活在放射性污染地区的儿童体内 137Cs 含量（Bq）与个人焦虑水平之间存在线性关联（b=-0.716，p<0.001）。
