The harsh climate of the North contributes to maladaptation manifested as desynchronosis. It is therefore advisable to evaluate the role of circadian rhythm disturbances in regulating blood pressure in the pathogenesis of hypertension.</p> <p><bold>Aim:</bold> This study aimed to investigate sex- and age-related variations in circadian rhythms among residents of northern regions with different blood pressure levels.</p> <p><bold>Methods:</bold> The study included 431 participants: 249 men and 182 women. Age stratification of blood pressure parameters was performed using the classification of postnatal human ontogenesis. The cohort was divided into subgroups with optimal blood pressure, normal blood pressure, and hypertension. All participants underwent 24-hour ambulatory blood pressure monitoring by standard methods. Circadian rhythms of blood pressure were analyzed using wavelet analysis.</p> <p><bold>Results:</bold> In individuals with optimal blood pressure, young men demonstrated substantial circadian rhythms of diastolic and mean arterial pressure. Women showed a more physiological pattern with circadian rhythms of systolic and diastolic blood pressure and heart rate. In the first period of adulthood, men exhibited ultradian rhythms in pulse pressure and circadian rhythms in heart rate, whereas women showed circadian rhythms in pulse pressure. In the second period of adulthood, men demonstrated circadian rhythms in diastolic and mean arterial pressure, whereas women showed circadian rhythms in systolic and diastolic blood pressure. In participants with normal blood pressure in the young age group, men exhibited disruption of biological rhythms of the studied parameters of 24-hour ambulatory blood pressure monitoring. In female participants, a circadian structure of systolic and mean arterial pressure rhythms was observed. In the first period of adulthood, there was only one case of circadian rhythm (systolic blood pressure) in men, whereas women demonstrated circadian rhythms in systolic, diastolic, and mean arterial pressure, as well as heart rate. In the second period of adulthood, circadian rhythms in diastolic and mean arterial pressure were observed in men and systolic, diastolic, and mean arterial pressure in women. Among participants with hypertension, the most optimal biorhythmic organization was observed in women in the second period of adulthood, characterized by three circadian rhythms (systolic, diastolic, and mean arterial pressure). However, in male individuals of the second period of adulthood, as well as in both male and female individuals in the first period of adulthood, complete disorganization of biological rhythms of the studied parameters of 24-hour ambulatory blood pressure monitoring was observed: in young men, ultradian rhythms in systolic and pulse arterial pressure and a circadian rhythm in diastolic arterial pressure were identified, whereas in women, circadian rhythms in systolic, diastolic, and mean arterial pressure, as well as heart rate, were observed.</p> <p><bold>Conclusion:</bold> Persistent elevation of blood pressure may result from multicomponent desynchronosis of its parameters. In residents of northern regions, signs of desynchronosis may be present even at optimal and normal blood pressure levels, likely due to climatic and geographic factors. This may explain the higher prevalence of hypertension in northern regions compared with Russian national averages.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Распространённость артериальной гипертензии (АГ) на территории Севера по сравнению общероссийскими показателями составляет 49 против 45%. Суровый климат Севера способствует развитию срыва адаптации, который выражается в виде десинхроноза. Таким образом, целесообразно оценить роль нарушений циркадианной структуры ритмов артериального давления (АД) в развитии АГ.</p> <p><bold>Цель.</bold> Изучить половозрастные вариации циркадианных ритмов у жителей северного региона с разным уровнем АД.</p> <p><bold>Методы.</bold> В общую выборку включён 431 респондент: лица мужского пола — 249, женского пола — 182. Для возрастной градации параметров АД пользовались схемой периодизации постнатального онтогенеза человека. Общая выборка была поделена на подгруппы: с оптимальным уровнем АД, с нормальным уровнем АД, а также подгруппа АГ. Всем испытуемым проводили суточное мониторирование АД согласно общепринятой методике. Для оценки биологических ритмов АД использовали метод вейвлет-анализа.</p> <p><bold>Результаты.</bold> У лиц с оптимальным уровнем АД в группе юношеского возраста у мужчин наблюдаются значимые циркадианные ритмы диастолического и среднего АД. У лиц женского пола наблюдается более физиологическая биоритмологическая картина: циркадианные ритмы систолического, диастолического АД и частоты сердечных сокращений (ЧСС). В возрастной группе первого периода зрелого возраста у лиц мужского пола выявлен ультрадианный ритм пульсового АД и циркадианный ритм ЧСС, у лиц женского пола — циркадианный ритм пульсового АД. В возрастной группе второго периода зрелого возраста у мужчин регистрируются циркадианные ритмы диастолического и среднего АД, у женщин — циркадианные ритмы систолического и диастолического АД. У лиц с нормальным уровнем АД в возрастной группе юношеского возраста у мужчин наблюдается деструктуризация биологических ритмов изучаемых показателей суточного мониторирования АД. У респондентов женского пола циркадианная структура ритма систолического и среднего АД. В группе первого периода зрелого возраста у мужчин зарегистрирован один циркадианный ритм — систолическое АД, у женщин — циркадианные ритмы систолического, диастолического и среднего АД, а также ЧСС. В группе второго периода зрелого возраста у лиц мужского пола определяются циркадианные ритмы диастолического и среднего АД, у женщин — систолического, диастолического и среднего АД. У лиц с<italic> </italic>АГ оптимальная биоритмическая организация отмечена у женщин в группе второго периода зрелого возраста из-за наличия трёх циркадианных ритмов – систолического, диастолического и среднего АД. Однако у лиц мужского пола группы второго периода зрелого возраста, а также лиц мужского и женского пола группы первого периода зрелого возраста наблюдается полная дезорганизация биологических ритмов изучаемых показателей суточного мониторирования АД: у мужчин юношеского возраста ультрадианные ритмы систолического и пульсового АД и циркадианный ритм диастолического АД, у женщин — циркадианные ритмы систолического, диастолического, среднего АД и ЧСС.</p> <p><bold>Заключение.</bold> Стойкое повышение АД может быть следствием мультикомпонентного десинхроноза его параметров. У лиц, проживающих в северных регионах, признаки десинхроноза проявляются даже при оптимальных и нормальных уровнях АД, что, вероятно, обусловлено воздействием климатогеографических особенностей региона. Это подтверждается большей распространённостью АГ на территории Севера по сравнению с общероссийскими данными.</p></trans-abstract><trans-abstract xml:lang="zh"><p>论证。北方地区高血压患病率为49%，高于全俄45%的平均水平。严酷的北方气候易导致适应功能失调，表现为节律失调。因此，有必要评估血压昼夜节律失调在高血压发展中的作用。</p> <p>目的。探究不同血压水平北方地区居民昼夜节律的性别与年龄差异。</p> <p>方法。研究共纳入431名受访者：男性249人，女性182人。采用人类出生后个体发育周期分期方案进行血压参数的年龄分层。将总体本分为三个亚组：理想血压组、正常血压组及高血压组。所有受试者均按照标准方法进行24小时动态血压监测，并采用小波分析法评估血压生物节律。</p> <p>结果。在青年年龄组血压水平最佳的男性中，可观察到显著的舒张压和平均动脉压昼夜节律。女性个体呈现更符合生理规律的生物节律特征：收缩压、舒张压及心率的昼夜节律。在第一成熟期年龄组中，男性个体出现脉压的超日节律和心率的昼夜节律，女性个体则呈现脉压的昼夜节律。在第二成熟期年龄组中，男性记录到舒张压和平均动脉压的昼夜节律，女性则表现为收缩压和舒张压的昼夜节律。在血压水平正常的青年年龄组男性中，动态血压监测指标的生物节律出现结构性紊乱。女性受访者则保持收缩压和平均动脉压的昼夜节律结构。在第一成熟期年龄组中，男性仅记录到一种昼夜节律——收缩压，而女性则具有收缩压、舒张压、平均动脉压以及心率的昼夜节律。在第二成熟期年龄组中，男性被检测出舒张压和平均动脉压的昼夜节律，而女性则被检测出收缩压、舒张压和平均动脉压的节律。对于高血压患者群体，第二成熟期年龄组女性因同时具备收缩压、舒张压和平均动脉压三种昼夜节律，显示出最优的生物节律组织特征。然而在第二成熟期年龄组男性群体，以及第一成熟期年龄组男女群体中，其血压昼夜监测指标的生物节律呈现完全紊乱状态： 青年男性表现为收缩压和脉压的超昼夜节律与舒张压的昼夜节律，女性则呈现收缩压、舒张压、平均动脉压及心率的昼夜节律特征。</p> <p>结论。持续性血压升高可能是其参数多组分失同步化的后果。居住在北部地区的人群中，即使血压处于最佳正常水平，仍会显现出昼夜节律失调的体征，这种现象很可能与该地区特殊的气候地理环境因素有关。与全俄数据相比，北部地区动脉高血压患病率更高，证实了这一情况。</p></trans-abstract><kwd-group xml:lang="en"><kwd>sex and age differences</kwd><kwd>blood pressure</kwd><kwd>circadian rhythms</kwd><kwd>desynchronosis</kwd><kwd>northern region</kwd><kwd>wavelet analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>половозрастные различия</kwd><kwd>артериальное давление</kwd><kwd>циркадианные ритмы</kwd><kwd>десинхроноз</kwd><kwd>северный регион</kwd><kwd>вейвлет-анализ</kwd></kwd-group><kwd-group xml:lang="zh"><kwd>性别年龄差异</kwd><kwd>动脉血压</kwd><kwd>昼夜节律</kwd><kwd>失同步症</kwd><kwd>北方地区</kwd><kwd>小波分析</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Balanova YuA, Kontsevaya AV, Myrzamatova AO, et al.
