to assess the impact of stressful life events occuring with the period of restrictive measures introductionconnected to the COVID-19 pandemic and during the full-scale Russian aggression, on the anthropometric indicators and body composition of children aged 10-17 years.
The research group consisted of 56 boys and 70 girls aged 10-17 years who lived in radioactively contaminated areas of Zhytomyr, Rivne, and Kyiv regions with a soil contamination density of 137Cs from 18 kBq/m2 to 235 kBq/m2. The impact of stressful factors was assessed using the stress perception scale (PSS-10).Weight, height, waist circumference (WC) and hip circumference (HC) were measured. Body mass index (BMI), ratioof WC to HC, ratio of WC to height were calculated. Body composition (fat content, skeletal muscle content, visceral fat index and basal metabolic rate) was determined using OMRON smart scales based on the bioelectrical impedance method.
The vast majority of examined children (76.19 %) had a high level of perceived stress, while girls in generalmore often considered certain life events as stressful. «Direct witnessing of hostilities» was the strongest triggeringstress factor, and «Location of a loudspeaker warning of danger near the house» was a reinforcing stress factor.«Negative impact of COVID-19» factor did not significantly affect the level of perceived stress at present. A probablecurrent effects of the interaction of gender, age and level of stress perception were established, which were characterized by a decrease in the level of stress perception in boys with minimum indicators at the age of 16-17 and, conversely, an increase in the level of stress perception in girls with maximum indicators at the same age. Gender andage characteristics of anthropometric values and indicators of body structure were determined. It was shown thatwith age, the index of visceral fat in boys gradually decreased, while in girls, on the contrary, it increased, reaching aprobable difference at the age of 16-17 years. Perceived stress level had direct correlations with weight, BMI, HC, WC,WtHR index, visceral fat index, total fat content and an inverse relationship with skeletal muscle content. The dependent variable visceral fat index and the categorical factor - level of perceived stress revealed a significant currentinteraction effect of sufficient power for both males and females. Anthropometric values and indicators of body structure had no probable dependence on the activity of 137Cs in the body of children and their average annual accumulated doses of internal radiation. A weak inverse relationship between the level of perceived stress and the activity of137Cs in the body of children and their average annual accumulated doses of internal radiation was established.
The vast majority of children perceive the events taking place in Ukraine as stressful. Several changesin anthropometric indices and indicators of body structure, in particular an increase in visceral fat index are closely related to the increased level of perceived stress. The level of perceived stress inversely correlated with the activity of 137Cs in the body of children and their average annual accumulated doses of internal radiation.
评估在因新冠疫情实施限制措施期间以及俄罗斯全面入侵期间发生的生活应激事件，对10至17岁儿童人体测量指标和身体成分的影响。
研究组由56名男孩和70名女孩组成，年龄在10至17岁之间，他们生活在日托米尔、罗夫诺和基辅地区受放射性污染的区域，土壤中137铯的污染密度为18 kBq/m²至235 kBq/m²。使用应激感知量表（PSS - 10）评估应激因素的影响。测量体重、身高、腰围（WC）和臀围（HC）。计算体重指数（BMI）、腰围与臀围之比、腰围与身高之比。基于生物电阻抗法，使用欧姆龙智能秤测定身体成分（脂肪含量、骨骼肌含量、内脏脂肪指数和基础代谢率）。
绝大多数接受检查的儿童（76.19%）有较高的应激感知水平，总体而言女孩更常将某些生活事件视为有压力的。“直接目睹敌对行动”是最强的触发应激因素，“房屋附近有扬声器发出危险警告”是增强应激因素。“新冠疫情的负面影响”因素目前对感知应激水平没有显著影响。确定了性别、年龄和应激感知水平相互作用的可能当前效应，其特征是16 - 17岁时指标最低的男孩应激感知水平下降，相反，同一年龄指标最高的女孩应激感知水平上升。确定了人体测量值和身体结构指标的性别和年龄特征。结果表明，随着年龄增长，男孩的内脏脂肪指数逐渐下降，而女孩则相反，呈上升趋势，在16 - 17岁时可能存在差异。感知应激水平与体重、BMI、HC、WC、腰臀比指数、内脏脂肪指数、总脂肪含量呈正相关，与骨骼肌含量呈负相关。因变量内脏脂肪指数和分类因素——感知应激水平显示，对男性和女性而言，目前都有显著的足够强度的相互作用效应。人体测量值和身体结构指标可能与儿童体内137铯的活性及其年平均内照射累积剂量无关。确定了儿童体内感知应激水平与137铯的活性及其年平均内照射累积剂量之间存在微弱的负相关关系。
绝大多数儿童认为乌克兰发生的事件有压力。人体测量指数和身体结构指标的一些变化，特别是内脏脂肪指数的增加与感知应激水平的升高密切相关。感知应激水平与儿童体内137铯的活性及其年平均内照射累积剂量呈负相关。
