При развитии висцерального ожирения на фоне инсулинорезистентности (ИР) прогрессируют липои  глюкозотоксичность в тканях, что нарушает метаболический баланс организма и является основным фактором развития сахарного диабета 2 типа (СД2). На сегодняшний день растет количество публикаций, освещающих вопрос роли циркадианных ритмов в контроле глюконеогенеза и липогенеза. В контексте развития СД2 все чаще упоминают процесс рассогласования ритмов (десинхроноз), для диагностики которого применяется расчет амплитудно-фазовых параметров. Таким образом, изучение нарушений циркадианных ритмов с помощью амплитудно-фазовых параметров и факторов, влияющих на них, представляет особый интерес у лиц с висцеральным ожирением, предиабетом, так как полученные данные могут быть применены в качестве маркеров доклинической диагностики СД2.</p></sec><sec><title>Цель</title><p>Цель. Выявить значимые различия параметров (амплитуды, акрофазы) циркадианных ритмов (гликемии натощак, базальной температуры тела, частоты сердечных сокращений) как маркеров десинхроноза в группах без нарушений углеводного обмена, но с наличием висцерального ожирения, предиабетом (нарушение гликемии натощак, тест нарушенной толерантности к глюкозе) и СД2.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование проведено у лиц, имеющих висцеральное ожирение, а также наличие предиабета или СД2, со стажем заболевания не более 5 лет. В соответствии с дизайном исследования каждые 3 ч в течение суток участники в домашних условиях производили самостоятельные измерения гликемии (с помощью индивидуальных глюкометров), базальной температуры тела (БТТ) в подмышечной впадине (с применением ртутного термометра) и частоты сердечных сокращений (ЧСС) (с помощью электронного тонометра) с фиксацией результатов в дневниках самоконтроля. Оценку циркадианных ритмов изучаемых показателей осуществляли с использованием основных хронобиологических параметров (МЕSOR — Midline Estimating Statistic of Rhytm, амплитуды колебаний ритма, акрофазы — времени максимума функции) с помощью косинор-анализа с построением эллипсов доверия. Результаты. Из 120 участников исследования женщин было 73%, а мужчин — 27%. Средний возраст участников — 58,6 [52,2; 56,7] года, ИМТ — 31,3 [29,7; 33,9] кг/м2 и наличие висцерального ожирения — объем талии 100 [93,8; 104,7] см. При проведении косинор-анализа суточные ритмы физиологических показателей гликемии натощак, БТТ и ЧСС имеют отличия от нормальных уже в группе с висцеральным ожирением без нарушений углеводного обмена и предиабетом в виде сокращения амплитуды суточных ритмов (р&lt;0,001) со смещением их акрофаз (р&lt;0,001), отсутствия динамики снижения ночной БТТ (р&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Интегральные амплитудно-фазовые параметры циркадианных ритмов физиологических показателей (гликемии натощак, БТТ, ЧСС) как маркеры десинхроноза могут применяться при наличии висцерального ожирения для доклинической диагностики предиабета и СД2, что будет иметь профилактическую направленность. Данный метод хронодиагностики может быть полезен в центрах здоровья и профилактики для лиц, входящих в группу риска развития СД2.</p></sec><sec><title> </title><p> </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>BACKGROUND</title><p>BACKGROUND: With the development of visceral obesity, against the background of insulin resistance (IR), lipo- and glucose toxicity in tissues progresses, which disrupts the metabolic balance of the body, and is the main factor in the development of type 2 diabetes mellitus (DM2). To date, a growing number of publications highlighting the role of circadian rhythms in the control of gluconeogenesis and lipogenesis. In the context of the development of DM2, the process of rhythm mismatch (desynchronosis) is increasingly mentioned, for the diagnosis of which the calculation of amplitude-phase parameters is used. Thus, the study of circadian rhythm disturbances using amplitude-phase parameters and factors influencing them is of particular interest in individuals with visceral obesity and prediabetes, since the data obtained can be used as markers for preclinical diagnosis of DM2.</p></sec><sec><title>AIM</title><p>AIM: To identify significant differences in the parameters (amplitude, acrophase) of circadian rhythms (fasting glycemia, basal body temperature, heart rate) as markers of desynchronosis in groups without carbohydrate metabolism disorders, but with the presence of visceral obesity, prediabetes (impaired fasting glycemia, impaired glucose tolerance test) and DM2 and obesity.</p></sec><sec><title>MATERIALS AND METHODS</title><p>MATERIALS AND METHODS: The study was conducted in individuals with visceral obesity, as well as the presence of prediabetes or DM2, with a disease experience of not more than 5 years.In accordance with the study design, every 3 hours during the day, the participants made self-measurements of blood glucose at home (using individual glucometers), basal body temperature (BTT) in the armpit (using a mercury thermometer) and heart rate (HR) ( with the help of an electronic tonometer), with the fixation of the results in self-control diaries. To assess the reliability of the circadian rhythms of the studied indicators, the interpretation of chronobiological parameters (MESORa-Midline Estimating Statistic of Rhytm; amplitude; acrophase) was carried out using a single сosinor analysis.</p></sec><sec><title>RESULTS</title><p>RESULTS: Of the 120 study participants, 73% were women and 27% were men. Mean age of participants was 58.6[52.2;56.7] years, BMI 31.3[29.7;33.9] and presence of visceral obesity WC 100 [93.8;104.7]. When conducting cosinor analysis, the daily rhythms of physiological indicators of fasting glycemia, BTT and heart rate differ from normal already in the group with visceral obesity without carbohydrate metabolism disorders and prediabetes, in the form of a decrease in the amplitude of daily rhythms (p&lt;0.001), with a shift in their acrophases (p &lt;0.001), no dynamics of night BBT decrease (р&lt;0.001).</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: Integral amplitude-phase parameters of circadian rhythms of physiological parameters (fasting glycemia, basal body temperature, heart rate), as markers of desynchronosis, can be used in the presence of visceral obesity for preclinical diagnosis of prediabetes and DM2, which will have a preventive focus. This method of chronodiagnostics can be useful in health and prevention centers for people at risk of developing DM2.</p></sec><sec><title> </title><p> </p></sec><sec><title> </title><p> </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ожирение</kwd><kwd>предиабет</kwd><kwd>сахарный диабет 2 типа</kwd><kwd>циркадианные ритмы</kwd><kwd>амплитуда</kwd><kwd>акрофаза</kwd><kwd>десинхроноз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obesity</kwd><kwd>prediabetes</kwd><kwd>type 2 diabetes</kwd><kwd>circadian rhythms</kwd><kwd>amplitude</kwd><kwd>acrophase</kwd><kwd>desynchronosis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовом и инструментальном обеспечении ГАУЗ ТО «Многопрофильный консультативно-диагностический центр»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Дедов И.И., Шестакова М.В., Мельниченко Г.А., и др.
