Efficacy of interventions for prevention and correction of overweight and obesity in children 7–8 years old: a meta-analysis

The rapid increase in overweight and obesity in children is a global public health problem. Interventions to reduce the prevalence of obesity before puberty are considered to be the most effective, but the results of trials are not consistent enough. We performed a meta-analysis of the efficacy of interventions to prevent or correct overweight and obesity in pre-pubertal children. Thirty-one Cochrane systematic reviews were analyzed, the results of 10 RCTs and two prospective comparative studies were extracted. All trials had an moderate or high risk of bias. According to the results of meta-analyzes, the prevention of overweight and obesity through recommendations of lifestyle modification is effective, the difference in a BMI decrease is -0.19, 95% CI [-0.35; -0.03], compared with the absence of intervention, in children 7–8 years old if applied within 2–4 years, but not within one year or less. The effect of non-drug interventions in children with overweight or obesity was not revealed

Comparative assessment of energy metabolism, body composition and metabolic features in children with hypothalamic and simple obesity

Background: Hypothalamic obesity often develops after surgical treatment of craniopharyngioma and is characterized by rapid weight gain, high frequency of metabolic disorders, body composition specificity and resistance to standard lifestyle modification approaches and medication therapy of obesity. Recent studies show that one of the mechanisms, explaining weight gain in these children is decrease in resting energy expenditure (REE).Aims: To compare REE, body composition parameters, and the frequency of metabolic disorders in children with hypothalamic and simple obesity.Materials and methods: The study included 60 obese children aged 7 to 17 years, divided into two groups. The study group included 20 children with hypothalamic obesity, developed after craniopharyngioma treatment. The control group consisted of 40 children with simple obesity. Body composition, REE, and metabolic disorders were associated in all children.Results: Children with hypothalamic obesity showed a significant decrease of resting energy expenditure. The average decrease in REE was 13.1%, but in single patients it reached 33.4%. The percentage of fat mass in hypothalamic and simple obesity does not differ significantly (39.7% [36.2; 42.6] vs 38.8 % [35.9; 43.2]; p=0.69). Screening for metabolic disorders revealed a high prevalence of metabolic disorders in hypothalamic obesity: impaired glucose tolerance - in 10%; dyslipidemia - 55%, insulin resistance-50%, non-alcoholic fatty liver disease - 60 %.Conclusions: Children with hypothalamic obesity showed a significant decrease of resting energy expenditure. When planning a diet in this group of patients it is preferable to use indirect calorimetry. Hypothalamic obesity even at an early age is associated with a high frequency of metabolic disturbance. Hypothalamic obesity in children is not associated with more pronounced hyperinsulinemia and insulin resistance compared to the simple obesity

Diabetes mellitus type 1 in childhood

Public organization “Russian Association of Endocrinologists”. Clinical guidlines

Standards of specialized diabetes care. Edited by Dedov I.I., Shestakova M.V., Mayorov A.Yu. 9th edition

Dear Colleagues! We are glad to present the 9th Edition (revised) of Standards of Diabetes Care. These evidence-based guidelines were designed to standardize and facilitate diabetes care in all regions of the Russian Federation. The Standards are updated on the regular basis to incorporate new data and relevant recommendations from national and international clinical societies, including World Health Organization Guidelines (WHO, 2011, 2013), International Diabetes Federation (IDF, 2011, 2012, 2013), American Diabetes Association (ADA, 2018, 2019), American Association of Clinical Endocrinologists (AACE, 2019), International Society for Pediatric and Adolescent Diabetes (ISPAD, 2014, 2018) and Russian Association of Endocrinologists (RAE, 2011, 2012, 2015). Current edition of the “Standards” also integrates results of completed randomized clinical trials (ADVANCE, ACCORD, VADT, UKPDS, SAVOR, TECOS, LEADER, EXAMINE, ELIXA, SUSTAIN, DEVOTE, EMPA-REG OUTCOME, CANVAS, DECLARE, CARMELINA, REWIND, etc.), as well as findings from the national studies of diabetes mellitus (DM), conducted in close partnership with a number of Russian hospitals. Latest data indicates that prevalence of DM in the world increased during the last decade more than two-fold, reaching some 463 million patients by the end of 2019. According to the current estimation by the International Diabetes Federation, 578 million patients will be suffering from diabetes mellitus by by 2030 and 700 million by 2045. Like many other countries, Russian Federation experiences a sharp rise in the prevalence of DM. According to Russian Federal Diabetes Register, there are at least 4 584 575 patients with DM in this country by the end of 2018 (3,1% of population) with 92% (4 238 503) – Type 2 DM, 6% (256 202) – Type 1 DM and 2% (89 870) – other types of DM, including 8 006 women with gestational DM. However, these results underestimates real quantity of patients, because they consider only registered cases. Results of Russian epidemiological study (NATION) con- firmed that only 54% of Type 2 DM are diagnosed. So real number of patients with DM in Russia is 9 million patients (about 6% of population). This is a great long-term problem, because a lot of patients are not diagnosed, so they don’t receive any treatment ant have high risk of vascular complications. Severe consequences of the global pandemics of DM include its vascular complications: nephropathy, retinopathy, coronary, cerebral, coronary and peripheral vascular disease. These conditions are responsible for the majority of cases of diabetes-related disability and death. In сurrent edition of the “Standards”: New goals of glycemic control for the elderly, based on the presence of functional dependence, as well as for pregnant women, children and adolescents, are given. Added a snippet that describes the continuous glucose monitoring. Only low-density lipoprotein cholesterol level is used as a target for lipid metabolism. Proposes more stringent target levels of blood pressure. It also features updated guidelines on stratification of treatment in newly diagnosed Type 2 diabetes: the excess of the initial level of HbA1c over the target level was used as a criterion. In the recommendations for the personalization of the choice of antidiabetic agents, it is taken into account that in certain clinical situations (the presence of atherosclerotic cardiovascular diseases and their risk factors, chronic heart failure, chronic kidney disease, obesity, the risk of hypoglycemia) certain classes of hypoglycemic agents (or individual drugs) have proven advantages. Recommendations for psychosocial support are added. The position of metabolic surgery as a method of treatment of DM with morbid obesity is updated. Recommendations for diagnostic and treatment of hypogonadism syndrome in men with DM are added. For the first time, evidence levels of confidence and credibility levels of recommendations for diagnostic, therapeutic, rehabilitative and preventive interventions based on a systematic review of the literature are given in accordance with the recommendations of the Center for Healthcare Quality Assessment and Control of the Ministry of Health of the Russian Federation. This text represents a consensus by the absolute majority of national experts, achieved through a number of fruitful discus- sions held at national meetings and forums. These guidelines are intended for endocrinologists, primary care physicians and other medical professionals involved in the treatment of DM. On behalf of the Working Grou

Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories: a pooled analysis of 2181 population-based studies with 65 million participants

Summary Background Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. Methods For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease Risk Factor Collaboration. We applied a Bayesian hierarchical model to estimate trends from 1985 to 2019 in mean height and mean BMI in 1-year age groups for ages 5–19 years. The model allowed for non-linear changes over time in mean height and mean BMI and for non-linear changes with age of children and adolescents, including periods of rapid growth during adolescence. Findings We pooled data from 2181 population-based studies, with measurements of height and weight in 65 million participants in 200 countries and territories. In 2019, we estimated a difference of 20 cm or higher in mean height of 19-year-old adolescents between countries with the tallest populations (the Netherlands, Montenegro, Estonia, and Bosnia and Herzegovina for boys; and the Netherlands, Montenegro, Denmark, and Iceland for girls) and those with the shortest populations (Timor-Leste, Laos, Solomon Islands, and Papua New Guinea for boys; and Guatemala, Bangladesh, Nepal, and Timor-Leste for girls). In the same year, the difference between the highest mean BMI (in Pacific island countries, Kuwait, Bahrain, The Bahamas, Chile, the USA, and New Zealand for both boys and girls and in South Africa for girls) and lowest mean BMI (in India, Bangladesh, Timor-Leste, Ethiopia, and Chad for boys and girls; and in Japan and Romania for girls) was approximately 9–10 kg/m2. In some countries, children aged 5 years started with healthier height or BMI than the global median and, in some cases, as healthy as the best performing countries, but they became progressively less healthy compared with their comparators as they grew older by not growing as tall (eg, boys in Austria and Barbados, and girls in Belgium and Puerto Rico) or gaining too much weight for their height (eg, girls and boys in Kuwait, Bahrain, Fiji, Jamaica, and Mexico; and girls in South Africa and New Zealand). In other countries, growing children overtook the height of their comparators (eg, Latvia, Czech Republic, Morocco, and Iran) or curbed their weight gain (eg, Italy, France, and Croatia) in late childhood and adolescence. When changes in both height and BMI were considered, girls in South Korea, Vietnam, Saudi Arabia, Turkey, and some central Asian countries (eg, Armenia and Azerbaijan), and boys in central and western Europe (eg, Portugal, Denmark, Poland, and Montenegro) had the healthiest changes in anthropometric status over the past 3·5 decades because, compared with children and adolescents in other countries, they had a much larger gain in height than they did in BMI. The unhealthiest changes—gaining too little height, too much weight for their height compared with children in other countries, or both—occurred in many countries in sub-Saharan Africa, New Zealand, and the USA for boys and girls; in Malaysia and some Pacific island nations for boys; and in Mexico for girls. Interpretation The height and BMI trajectories over age and time of school-aged children and adolescents are highly variable across countries, which indicates heterogeneous nutritional quality and lifelong health advantages and risks

Heterogeneous contributions of change in population distribution of body mass index to change in obesity and underweight NCD Risk Factor Collaboration (NCD-RisC)

From 1985 to 2016, the prevalence of underweight decreased, and that of obesity and severe obesity increased, in most regions, with significant variation in the magnitude of these changes across regions. We investigated how much change in mean body mass index (BMI) explains changes in the prevalence of underweight, obesity, and severe obesity in different regions using data from 2896 population-based studies with 187 million participants. Changes in the prevalence of underweight and total obesity, and to a lesser extent severe obesity, are largely driven by shifts in the distribution of BMI, with smaller contributions from changes in the shape of the distribution. In East and Southeast Asia and sub-Saharan Africa, the underweight tail of the BMI distribution was left behind as the distribution shifted. There is a need for policies that address all forms of malnutrition by making healthy foods accessible and affordable, while restricting unhealthy foods through fiscal and regulatory restrictions

Use of telemedicine improves glycemic control and quality of life in type 1 diabetes children on insulin pump therapy

Rationale: Healthcare access plays a significant role in the improvement and maintaining of glycemic control and quality of life in type 1 diabetes mellitus (T1DM) patients on continuous subcutaneous insulin infusion (CSII). Aims: The aim of the study was to evaluate the feasibility of remote support in children and adolescents with type 1 diabetes mellitus (T1DM) and its effect on glycemic control and quality of life. Materials and methods: In 40 children and adolescents (132,7 years, 18/22 m/f) on CSII with inadequately controlled T1DM (HbA1c7,5%) we evaluated the effectiveness of telemedical support (TS), as compared with conventional support (CS). Parameters of glycemic control (HbA1c, average glycemia, SD, etc.) and quality of a life were obtained on follow-up visits. Patients and their parents in ТМ group twice a month sent their insulin pump data using to CSII center and diabetologists sent back their advice via e-mail, phone or Skype. The primary end point was the change from the baseline HbA1c level and the proportion of patients achieving HbA1c of less than 7.5%. Results: At 24 weeks, the baseline mean HbA1c (8.7% in the two study groups) had decreased to 7.7% in the TS group, as compared with 8.4% in the CS group (P0,05). The proportion of patients who reached the HbA1c target (7,5%) was greater in the TS group (50%) than in the CS group (20%, p0,05). A number of quality of life indicators for both parents and children with T1DM at the end of the study compared to baseline significantly increased in the TS group compared with the TC group (p0.05). During the study period rate of severe hypoglycemia and DKA in TS group (0 and 10 cases per 100 person-years) did not differ significantly from that in CS group (0 and 20 cases per 100 person-years, P0,05). Conclusion: In children with inadequately controlled T1DM, telemedical support proved to be feasible and resulted in significant improvement in glucose control (HbA1c, glucose variability) and quality of life without the increase in the incidence of DKA and severe glycemia

Otdalennye rezul'taty lecheniya diabeticheskoy nefropatii u detey i podrostkov s sakharnym diabetom tipa 1

Цель: настоящего исследования явилось катамнестическое наблюдение детей с ДН и оценка влияния патогенетической терапии на эволюцию ДН. Материалы и методы: В детском отделении ЭНЦ с 1996 по 1999 г. на стационарном/амбулаторном лечении находилось 738 больных СД 1 типа в возрасте от 1 д о 17 лет с различной длительностью заболевания. Скрининг ДН, проведенный у 520 больных, выявил 71 пациента (13%) с впервые обнаруженной альбуминурией. Обследование больных с целью уточнения генеза альбуминурии выявило, что у 12 пациентов причиной повышенной экскреции белка являлась ИМС, у 6 из 71 пациента имела место ортостатическая протеинурия. Динамическое наблюдение (от 3 до 12 месяцев) за остальными 57 больными показало, что у 11 обследуемых микроальбинурия (МАУ) регрессировала, у 46 оставалась стабильной или прогрессировала. Результаты: Значимое снижение альбуминурии и протеинурии на фоне лечения ингибиторами АПФ и гликозаминогликанами при неизменной компенсации углеводного обмена свидетельствует о высокой эффективности указанных препаратов в лечении подростков, с ДН. Отда-лённые результаты лечения показали, что только у 50% больных с МАУ сохранялось существенное снижение экскреции альбумина по сравнению с исходным, у 22% ? снижение д о нормы с сохранением антипротеинурического эффекта в среднем д о 6,6 мес. Повторные курсы применения ингибиторов позволяли сохранить достигнутый эффект у 12% больных. У больных на доклинической стадии наиболее эффективным является назначение ингибиторов при уровне МАУ < 100 мг/сут. В пользу этого свидетельствует тот факт, что наибольший процент больных с достижением нормоальбуминурии и наименьшая продолжительность курса лечения ингибиторами АПФ отмечались у больных с минимально исходным уровнем МАУ

Sulodeksid v lechenii diabeticheskoy nefropatii u podrostkov

Актуальность. Мультифакториальнось механизмов развития диабетического поражения почек, а также отсутствие эффективных средств лечения и профилактики ДН диктует необходимость поиска препаратов, способных предотвратить или замедлить развитие ДН. Среди препаратов, появившихся на рынке лекарств в последние годы, привлекает внимание препарат из группы гликозаминогликанов (ГАГ) ? сулодексид. Цель. Изучение эффективности препаратов, содержащих ГАГ, при ДН у подростков; в детском отделении ЭНЦ впервые в России в рамках открытого контролируемого исследования применен сулодексид. Материалы и методы. Сулодексид использовали при лечении 17 подростков с ИЗСД. Согласно протоколу исследований, продолжительность курса лечения сулодексидом составила 4 нед. Эффект лечения оценивался по динамике альбуминурии. В процессе лечения оценивали также влияние сулодексида на липидный обмен, систему гемокоагуляции и функциональное состояние почек. Комплекс обследования включал общеклинические методы, определение экскреции альбумина в суточной моче иммунотурбодиметрическим методом, определение скорости клубочковой фильтрации по клиренсу эндогенного креатинина; состояние гемостаза оценивали по показателям тромбоэластограммы, активированного времени рекальцификации (АВР), активированного частичного тромбопластинового времени (АЧТВ), протромбинового индекса, концентрации фибриногена определялись на коагулометре. Результаты. Назначение сулодексида подросткам с ДН приводит к существенному снижению альбуминурии (77%) с длительным сохранением протекторного эффекта после отмены препарата. Антипротеинурический эффект наступал в более ранние сроки, был более выраженным и стойким у больных с микроальбуминурией. Выводы. Назначение сулодексида в течение 4 нед. при диабетической нефропатии оказывает достоверный антипротеинурический эффект у абсолютного большинства больных; более выраженный положительный эффект наблюдается при начальных стадиях нефропатии. Лечение сулодексидом положительно влияет на липидный обмен у подростков с ДН, что проявляется в снижении уровня холестерина и триглицеридов
