Morphofunctional asymmetries of the female body (lateral phenotype) are an important constitutional trait influencing stress resilience, in the formation of which the nervous and humoral regulatory systems play a leading role.</p> <p><bold>AIM: </bold>The work aimed to study the features of the hormonal status in pregnant women with varying stress levels caused by prolonged residence in a war zone, depending on the type of lateral constitution.</p> <p><bold>METHODS: </bold>Design: a prospective, selective, comparative study involving a non-random, stratified, continuous sample of respondents aged 18–28 years, with a first singleton pregnancy of uncomplicated course, no signs of obstetric condition according to clinical, hormonal, biochemical, ultrasound, and Doppler examinations, and who had lived in the corresponding region for at least three years prior to pregnancy. The study assessed the lateral phenotype, stress level, adaptive potential of the circulatory system, situational and trait anxiety, hormonal profile, hemogram and coagulation parameters.</p> <p><bold>RESULTS: </bold>Assessment of the lateral phenotype in pregnant women revealed a predominance of low stress levels in those with a right lateral phenotype, and high stress levels in those with an ambidextrous phenotype. A decrease in 6-sulfatoxymelatonin levels (by an average of 35.1%) and sex hormones (by 12.6%) was found in pregnant women from the Donetsk and Luhansk People’s Republics compared to residents of the Rostov Region. Depending on the lateral phenotype, the highest levels of stress-response hormones were observed in women with an ambidextrous phenotype. Multifactorial decision tree analysis established that in pregnant women from the Donetsk and Luhansk People’s Republics, the leading factors in mechanisms of stress resilience formation were the adaptive potential of the cardiovascular system, melatonin levels, sex and stress-liberating hormones, body mass index, and age. At the same time, in residents of the Rostov Region, the hierarchy of influencing factors was represented by stress-response hormones, situational anxiety level, and hematologic parameters.</p> <p><bold>CONCLUSION: </bold>In the ambidextrous type of lateral constitution, higher production of stress-response hormones combined with reduced melatonin production is significantly associated with the development of high stress levels, regardless of region of residence, indicating the highest stress vulnerability of this lateral constitution type compared to polar right and left lateral phenotypes. The higher prevalence of high stress levels (1.8-fold) in pregnant women with an ambidextrous phenotype from the Donetsk and Luhansk People’s Republics, compared with residents of the Rostov Region, indicates a more pronounced decrease in stress resilience in women who had lived in a war zone prior to relocation.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Особенности адаптационной специфики регуляторных процессов у беременных, длительно проживавших в зоне военных действий, представляют особый научный интерес в связи с высокой стресс-уязвимостью данной категории обследуемых. Морфофункциональные асимметрии женского организма (латеральный фенотип) являются важным конституциональным признаком, опосредующим стресс-устойчивость, в формировании которой ведущие позиции принадлежат нервному и гуморальному контурам регуляции.</p> <p><bold>Цель исследования. </bold>Изучение особенностей гормонального статуса у беременных при различных уровнях стресса, обусловленных длительным проживанием в зоне военных действий, в зависимости от характера латеральной конституции.</p> <p><bold>Методы.</bold> Дизайн: проспективное выборочное сравнительное исследование, включавшее неслучайный стратифицированный сплошной отбор респонденток в возрастном диапазоне 18–28 лет, с первой одноплодной беременностью с неосложнённым течением, отсутствием признаков акушерской патологии по итогам клинических, гормональных, биохимических, ультразвуковых и допплерометрических исследований, проживавших в соответствующем регионе до наступления беременности не менее трёх лет. В исследовании определяли латеральный фенотип, уровень стресса, адаптационный потенциал системы кровообращения, ситуативную и личностную тревожность, гормональный профиль, параметры гемограммы и коагулограммы.</p> <p><bold>Результаты.</bold> При определении характера латерального фенотипа у беременных установлено доминирование низкого уровня стресса преимущественно при правом латеральном фенотипе, высокого — у женщин с амбидекстральным латеральным фенотипом. Выявлено снижение содержания 6-сульфатоксимелатонина (в среднем на 35,1%) и половых гормонов (на 12,6%) у беременных из Донецкой и Луганской Народных Республик по сравнению с жительницами Ростовской области. В зависимости от характера латерального фенотипа наибольшие показатели гормонов стресс-реализующей группы выявлены у женщин с амбидекстральным фенотипом. По результатам многофакторного анализа «Деревья решений» установлено, что в механизмах формирования стресс-устойчивости у беременных из Донецкой и Луганской Народных Республик ведущие позиции принадлежат адаптационному потенциалу сердечно-сосудистой системы, содержанию мелатонина, половых и стресс-либерирующих гормонов, индексу массы тела и возрасту женщин. В то же время у жительниц Ростовской области иерархия значимости влияющих признаков представлена стресс-реализующей группой гормонов, уровнем ситуативной тревожности и показателями системы крови.</p> <p><bold>Заключение.</bold> При амбидекстральном типе латеральной конституции при более выраженной продукции гормонов стресс-реализующей группы и снижении продукции мелатонина значимо чаще развивается высокий уровень стресса, независимо от региона проживания беременных, что свидетельствует о наибольшей стресс-уязвимости данного типа латеральной конституции по сравнению с полярными правым и левым латеральными фенотипами. БÓльшая частота высокого уровня стресса (в 1,8 раза) у беременных с амбидекстральным фенотипом из Донецкой и Луганской Народных Республик, по сравнению с жительницами Ростовской области, свидетельствует о более выраженном снижении стресс-устойчивости беременных, проживавших в регионе проведения военных действий до переселения.</p></trans-abstract><trans-abstract xml:lang="zh"><p>论证。长期居住在战区的孕妇在调节过程的适应性特征方面具有较高的压力易感性，这一特殊人群的研究具有重要的科学意义。女性机体的形态功能不对称性（侧化表型）是影响压力耐受性的重要体质特征，其中神经和体液调节环路在压力耐受性的形成中起主导作用。</p> <p>目的。探讨长期居住在战区的孕妇在不同压力水平下的激素状态特点，并分析其与侧化体质类型的关系。</p> <p>材料与方法。设计：本研究为前瞻性、抽样、比较性研究，采用非随机分层全群抽样，纳入年龄18–28岁、首次单胎妊娠且妊娠过程无并发症的孕妇，这些孕妇在临床、激素、生化、超声及多普勒检查中均未发现产科病理表现，并且在孕前已在相应地区连续居住不少于三年。研究内容包括侧化表型鉴定、压力水平评估、循环系统适应潜能、情境性与特质性焦虑、激素谱、血常规及凝血功能参数测定。</p> <p>结果。研究发现，右侧化表型孕妇以低压力水平为主，而双手灵活型孕妇中高压力水平更为常见。来自Donetsk和Lugansk人民共和国的孕妇，其6-硫酸氧基褪黑素水平（平均降低35.1%）和性激素水平（降低12.6%）较Rostov州孕妇显著偏低。在侧化表型的分型中，双手灵活型孕妇表现出最高水平的应激实现类激素。多因素分析（决策树模型）显示，在Donetsk和Lugansk人民共和国孕妇的压力耐受性形成机制中，循环系统适应潜能、褪黑素水平、性激素与应激释放类激素水平、体质指数和年龄占据主导地位。而在Rostov州孕妇中，影响因素的优先顺序为应激反应实现类激素水平、情境性焦虑水平以及血液系统指标。</p> <p>结论。在双手灵活型侧化体质孕妇中，应激反应实现类激素分泌较高且褪黑素分泌降低，高压力水平的发生率显著更高，无论居住地区如何，这提示该类型相比极端的右侧化和左侧化表型更易受压力影响。来自Donetsk和Lugansk人民共和国的双手灵活型孕妇高压力水平发生率（高1.8倍）较Rostov州孕妇更高，表明在迁居前长期居住在战区的孕妇在压力耐受性方面下降更为明显。</p></trans-abstract><kwd-group xml:lang="en"><kwd>pregnancy</kwd><kwd>lateral phenotype</kwd><kwd>hormonal status</kwd><kwd>stress</kwd><kwd>extreme exposure</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>беременность</kwd><kwd>латеральный фенотип</kwd><kwd>гормональный статус</kwd><kwd>стресс</kwd><kwd>экстремальные воздействия</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>妊娠</kwd><kwd>侧化表型</kwd><kwd>激素状态</kwd><kwd>压力</kwd><kwd>极端暴露</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Radzinsky VE, Botasheva TL, Kotaysh GA, editors.
