Тяжёлые металлы (ТМ) могут накапливаться в организме человека и влиять на его здоровье, в том числе вызывать гипертензию.</p><p>Цель исследования – установление связи между содержанием свинца, кадмия, марганца, никеля в почве и цельной крови пациентов с распространённостью артериальной гипертензии (АГ) среди взрослого населения Кизилюртовского района Дагестана.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Отбор проб почв (смешанных образцов) проведён с площадок с однородным почвенным покровом. В каждом населённом пункте отбирали по 10 почвенных проб. Цельную кровь брали у 10 пациентов из каждого из 11 населённых пунктов, всего у 110 участников в возрасте от 18 до 60 лет с АГ. Анализы почв и цельной крови на содержание ТМ проводили в трёхкратной повторности с использованием атомно-абсорбционный спектрометрии на приборе МГА-915МД. Для изучения связи между показателями ТМ и АГ у населения использовали модели линейной регрессии. Полученные данные обработаны с использованием программного обеспечения Python (версия 3.10.9), R. (версия 4.1.2) и пакета прикладных программ Statistica 6.0. Статистическую значимость определяли как значение p &lt; 0,05.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что накопление свинца в почвах населённых пунктов Кизилюртовского района составляло 8‒41 мг/кг, что эквивалентно 0,13‒0,68 предельно допустимой концентрации (ПДК) подвижной формы этого элемента; содержание кадмия – 0,87 ПДК, марганца – 0,89, никеля – 0,14. Статистический анализ показателей содержания ТМ в почвах исследуемой территории и данных о распространённости АГ указывает на прямую связь слабой силы для кадмия, марганца, никеля и заметной силы для свинца по шкале Чеддока. При анализе цельной крови пациентов с АГ также обнаружена статистически значимая связь средней и высокой силы между содержанием свинца и кадмия с АГ.</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования. Ограничения исследования связаны с разовым отбором проб в течение одного года.</p></sec><sec><title>Заключение</title><p>Заключение. Исследование показало значимую связь между уровнями содержания ТМ и распространённостью АГ. Уровень ТМ в почве может играть существенную роль в этиологии АГ, что свидетельствует о значимом воздействии геохимической среды на её развитие. Следовательно, важно учитывать содержание в почвах ТМ, поскольку они могут попадать в организм человека через пищевую цепь и накапливаться, влияя на элементный статус.</p><p>Соблюдение этических стандартов. Исследование соответствовало Хельсинкской декларации Всемирной медицинской ассоциации (ред. 2013 г.), программа была утверждена на заседании Учёного совета ФГБОУ ВО «Дагестанский государственный медицинский университет» Минздрава России (протокол № 25 от 24.02.2025 г.).

Heavy metals (HM) can accumulate in the human body and affect its health, including causing hypertension.</p><p>The aim of the study was to establish a relationship between the content of lead, cadmium, manganese, and nickel in soil and whole blood in patients with the prevalence of arterial hypertension (AH) among the adult population of the Kizilyurt region of Dagestan.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Soil sampling was carried out from sites with a homogeneous soil cover, from which mixed soil samples were taken. In each locality, ten soil samples were taken. Whole blood was taken from 10 patients from each 11 localities, from a total of 110 participants aged 18 to 60 years with hypertension pathology. Soil and whole blood analyses for TM content, in 3-fold repetition were performed using atomic absorption spectrometry on an MGA-915MD instrument. Linear regression models were used to study the relationship between HM and AH indicators of the population. The data obtained were processed using Python software (version 3.10.9), K. (version 4.1.2), and the Statistica 6.0 software package. Statistical significance was determined as a p value of less than 0.05.</p></sec><sec><title>Results</title><p>Results. Accumulation of lead in the soils of settlements in the Kizilyurt region was found to vary from 8 mg/kg to 41 mg/kg, which is equivalent to 0.13–0.68 of maximum permissible concentration (MPC) of the mobile form of this element. The content of cadmium is 0.87, manganese is 0.89, and nickel is 0.14 MPC. Statistical analysis of the HM content in the soils of the studied area and data on the prevalence of AH indicates to a direct relationship between the weak strength for cadmium, manganese, nickel and the noticeable strength for lead on the Chaddock scale. When analyzing the whole blood in patients with hypertension, a statistically significant association of lead and cadmium levels with pathology was also found to be of medium and high strength. </p></sec><sec><title>Limitations</title><p>Limitations. The limitations of the study are related to one-time sampling during one year.</p></sec><sec><title>Conclusion</title><p>Conclusion. This study showed a significant relationship between TM levels and the prevalence of hypertension. The level of TM in the soil can play a significant role in the etiology of hypertension, which indicates a significant impact of the geochemical environment on its development. Therefore, it is important to take into account the content of HMS in soils, since they can enter the human body through the food chain and accumulate, affecting its elemental status.</p><p>Compliance with ethical standards.
