Endemic goiter is considered a manifestation of regional biogeochemical maladaptation, where the primary role in thyroid hyperplasia development is attributed to environmental goitrogens and macro- and microelement imbalances.</p> <p><bold>AIM:</bold> To evaluate elemental imbalance using an integral indicator, which is the adaptation coefficient of the body’s elemental system, in young women at peak reproductive age, depending on their serum thyroid-stimulating hormone (TSH) levels.</p> <p><bold>MATERIALS AND METHODS:</bold> The concentrations of 25 macro- and microelements in hair samples were determined using a spectrometric method. Serum TSH levels were measured using an immunochemiluminescent method with paramagnetic particles.</p> <p><bold>RESULTS:<italic> </italic></bold>The pattern of elemental imbalance in women with low-normal or high-normal TSH levels is similar in terms of elemental deficiencies. However, the total deficiency rate differed significantly, reaching 323% in the low-normal TSH group and 203% in the high-normal TSH group. Elemental excesses were rare and primarily found in the high-normal TSH group.</p> <p><bold>CONCLUSION:</bold> The obtained data highlight the adaptation coefficient of the body’s elemental system as an informative marker of intra- and intersystem elemental shifts in assessing various functional states and risks. In the low-normal TSH group, this coefficient was 86.50 conventional units, slightly exceeding the value observed in the high-normal TSH group — 75.33 conventional units.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование. </bold>Актуальность обусловлена наличием на северной территории (Магадан) постоянного очага зобной эндемии. Зобная эндемия рассматривается как проявление региональных биогеохимических дезадаптаций, где основная роль в развитии гиперплазии отводится воздействию экологических струмогенов и дисбалансу макро- и микроэлементов.</p> <p><bold>Цель.</bold> Оценка элементного дисбаланса посредством интегрального показателя — коэффициента степени адаптированности элементной системы организма молодых женщин в фазе наивысшей репродуктивной активности в зависимости от уровня сывороточного тиреотропного гормона.</p> <p><bold>Материалы и методы.</bold> Содержание 25 макро- и микроэлементов в волосах определяли спектрометрическим методом, уровень содержания тиреотропного гормона — иммунохемилюминесцентным методом с использованием парамагнитных частиц.</p> <p><bold>Результаты.</bold> Характер элементного дисбаланса в группах женщин с низко- и высоконормальным уровнем сывороточного тиреотропного гормона имеет общие черты в части набора элементов в дефиците, однако общая суммарная частота дефицита значительно различается: наибольшая в группе женщин с низконормальным уровнем сывороточного тиреотропного гормона — 323% против 203% у женщин с высоконормальным показателем. Избытки элементов встречаются в единичных случаях, в основном в группе с высоконормальным уровнем тиреотропного гормона.</p> <p><bold>Заключение.</bold> Полученные данные позволяют выделить в числе подходов к оценке элементного статуса организма человека при различных функциональных состояниях и рисках коэффициент степени адаптированности системы как информативный маркер внутри- и межсистемных элементных перестроек, который в группе с низконормальным уровнем тиреотропного гормона составил 86,50 усл. ед., что несколько выше значения в группе с высоконормальным содержанием тиреотропного гормона — 75,33 усл. ед.</p></trans-abstract><trans-abstract xml:lang="zh"><p>论证。由于俄罗斯北部（Magadan）长期存在地方性甲状腺肿病区，该现象的研究尤为重要。地方性甲状腺肿被视为区域性生物地球化学失调的表现，其主要诱因包括环境甲状腺肿诱导物的作用以及宏量和微量元素的失衡。</p> <p>目的。通过整合指标——元素系统适应指数，评估处于生育高峰期的年轻女性机体元素系统的失衡情况，并分析其与血清促甲状腺激素（TSH, thyroid stimulating hormone）水平的关系。</p> <p>材料与方法。采用光谱分析法测定头发样本中25种宏量和微量元素的含量，促甲状腺激素水平采用基于顺磁性颗粒的化学发光免疫测定法进行检测。</p> <p>结果。在血清TSH水平处于低正常和高正常范围的女性群体中，元素失衡的特征在缺乏元素的组成上具有相似性，但元素缺乏的总发生率存在显著差异：TSH水平处于低正常范围的女性群体中，元素缺乏的总发生率最高，为323%；而在高正常范围的女性群体中，该数值为203%。元素过量现象较为罕见，主要发生于TSH水平较高的群体。</p> <p>结论。研究结果表明，在评估人体元素状态于不同功能状态和健康风险下的各种方法中，元素系统适应指数可作为衡量体内及系统间元素重组的有效标志物。在TSH水平处于低正常范围的女性群体中，该指数为86.50（单位），略高于TSH水平处于高正常范围的女性群体（75.33单位）。</p></trans-abstract><kwd-group xml:lang="en"><kwd>macroelements</kwd><kwd>microelements</kwd><kwd>imbalance</kwd><kwd>adaptive potential</kwd><kwd>North</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>макроэлементы</kwd><kwd>микроэлементы</kwd><kwd>дисбаланс</kwd><kwd>адаптационный потенциал</kwd><kwd>Север</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>宏量元素</kwd><kwd>微量元素</kwd><kwd>元素失衡</kwd><kwd>适应能力</kwd><kwd>北部。</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российская академия наук</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Academy of Sciences</institution></institution-wrap><institution-wrap><institution xml:lang="zh">Russian Academy of Sciences</institution></institution-wrap></funding-source><award-id>124111200092-3</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Ulyanovskaya SA, Bazhenov DV, Shestakova VG, Kalinkin MN.
