Association between vitamin D status and obesity in Bulgarian pre-pubertal children: a pilot study

Background: It is considered that obesity and metabolic syndrome are accompanied with vitamin D deficiency. We aimed to examine the interrelations between vitamin D status and biomarkers for metabolic syndrome in Bulgarian pre-pubertal children.Methods: The study enrolled 51 pre-pubertal children (29 boys, 22 girls) examined for serum 25-xydroxyvitamin D, and routine parameters for metabolic syndrome. Obesity was evaluated by body mass index and waist circumference.Results: More than half (57.1%) of the studied children were vitamin D deficient, prevalent in girls than in boys (65.0% vs. 51.7% respectively). A tendency for worse metabolic status in the vitamin D-deficient group, expressed by higher fasting insulin, total cholesterol, total cholesterol/HDL-ratio and Homeostasis Model Assessment (HOMA)-index was observed. A trend for negative correlation was established between 25-xydroxyvitamin D and waist circumference, HOMA-index, and fasting insulin.Conclusions: Vitamin D deficiency and inverse relationships between 25-xydroxyvitamin D and waist circumference, HOMA-index, and insulin were found amongst studied children

Educational and knowledge gaps within the European reference network on rare endocrine conditions

Objective: The European Reference Network on Rare Endocrine Conditions (Endo-ERN), operational since 2017, consists of 71 health care providers (HCPs) in 19 EU member states. Our objective was to assess education and knowledge on rare endocrine conditions. Design and methods: A survey was developed and sent through the DIGIT-EUROSURVEY system to all Endo-ERN HCPs. Results: Response rate was 55% (n = 146), 95% physicians, 58% > 20 years of experience, 96% academics. Largest knowledge gaps were reported for the transition and neonatal ages, and for the GPs. Less than 50% of HCPs had structured educational rare diseases (RD) plans, while 86% used RD specific guidelines. HCPs would share educational materials within Endo-ERN (74%), and participate in an accreditation model (85%). E-learning portals of the endocrine scientific societies used 58 % (ESPE) and 64% (ESE). Most participants (90%) regarded Endo-ERN coordinated educational activities (annual meetings slots, webinars, etc.) as highly important and supported a common educational platform. Social media was perceived as important for educating patients (86%) but not for physicians (36%). Seventy-five % had developed patient education materials; only 31% had specific children's materials, and by-country avail ability varied from 0 to 100%. Respondents provided newly diagnosed patients with their own material in the national language (81%); referred to advocacy groups (68%), and relevant online sources (50%). Respondents believed the European Commission should fund education through Endo-ERN. Conclusion: Identified knowledge gaps in rare endocrine disorders set the basis for fast catch-up through collaboration, alignment with patients' needs, and further development of existing and newly developed educational resources.Peer reviewe

Access to patient oriented information-a baseline Endo-ERN survey among patients with rare endocrine disorders

Aim To perform a baseline survey on condition-specific information access among patients/parents/caregivers with rare endocrine disorders (RD) in Europe. Methods Electronic invitation to participate in a survey (19 questions) was sent to 120 patient advocacy groups (PAGs), and further distributed to 32 European countries. Results A total of 1138 respondents from 22 countries (74% women), aged between 1 year (parents) and 70 years, participated. The Netherlands, France, Germany, Italy and France had highest participation rates. All Main Thematic Groups (MTGs) were represented; the adrenal (32%), pituitary (26%) and thyroid (22%) were the most common. The majority of the respondents got information from their endocrinologist (75%), PAGs (37%) and expert reference centre (22%); 95% received information in their mother tongue. Leaflets (70%), infographics (65%), webinars (60%) and Internet films (55%) were preferred ways of learning. Respondents relied mostly on materials by PAGs and alliances (79%), rather than from specific international RD sites (15%). Fifty-six percent used Facebook, and 37% other social media, with a significant age difference (40 years) among non-users, 19% vs. 36%, p <0.0001. Of all, 685 answered questions on informational materials for children-79% wanted materials that can be used by the children themselves. There was significant age difference (40 years) in the willingness to help create new educational materials; 49% vs. 34%, p <0.001. Conclusions Our current patient information access survey provides a sound basis for further planning and execution of educational and teaching activities by Endo-ERN.Peer reviewe

An overview of the outreach of the 2019–2021 Endo-ERN knowledge generation webinars

The current study aims to assess the development of the knowledge generation program of the European Reference Network on Rare Endocrine Conditions (Endo-ERN) from its start in 2019 until December 2021, with special reference to webinars. We analyzed the number of webinars and live/postevent participants and whether participation and engagement of the attendees changed over time. A total of 30 (86%) self-prepared webinars comprising 300 h of knowledge and competence sharing were broadcasted (2019 – 3; 2020 – 13; 2021 – 14). A total of six webinars were broadcasted live prior to the coronavirus disease 2019 pandemic (https://endo-ern.eu/events/webinars/). The most active main thematic group (MTG) was MTG3 Genetic Disorders of Glucose and Insulin Homeostasis with eight (27%) webinars. Two (25%) MTGs fulfilled the goal to prepare at least two to three webinars per year. Patients were actively involved in 20% of the accounted webinars as both creators and presenters. The total number of live and postevent participants was 3023. The availability of the webinars after the live broadcast increased their outreach with a larger number of postevent viewers (n = 1629, 54%). Within the formal structured evaluation of the webinars, 40–85% of the participants replied on separate occasions and helped improve content. The free webinar access is among the perceived reasons for the rapidly increasing number of total hits to the Endo-ERN website. In conclusion, for its short existence, the Endo-ERN rapidly developed educational outreach, and further efforts to attract creators and learners are warranted

Frequency of family meals and food consumption in families at high risk of type 2 diabetes: the Feel4Diabetes-study

A family meal is defined as a meal consumed together by the members of a family or by having> 1 parent present during a meal. The frequency of family meals has been associated with healthier food intake patterns in both children and parents. This study aimed to investigate in families at high risk for developing type 2 diabetes across Europe the association (i) between family meals'' frequency and food consumption and diet quality among parents and (ii) between family meals'' frequency and children''s food consumption. Moreover, the study aimed to elucidate the mediating effect of parental diet quality on the association between family meals'' frequency and children''s food consumption. Food consumption frequency and anthropometric were collected cross-sectionally from a representative sample of 1964 families from the European Feel4Diabetes-study. Regression and mediation analyses were applied by gender of children. Positive and significant associations were found between the frequency of family meals and parental food consumption (beta = 0.84; 95% CI 0.57, 1.45) and diet quality (beta = 0.30; 95% CI 0.19, 0.42). For children, more frequent family meals were significantly associated with healthier food consumption (boys, beta = 0.172, p < 0.05; girls, beta = 0.114, p< 0.01). A partial mediation effect of the parental diet quality was shown on the association between the frequency of family meals and the consumption of some selected food items (i.e., milk products and salty snacks) among boys and girls. The strongest mediation effect of parental diet quality was found on the association between the frequency of family breakfast and the consumption of salty snacks and milk and milk products (62.5% and 37.5%, respectively) among girls. Conclusions: The frequency of family meals is positively associated with improved food consumption patterns (i.e., higher intake of fruits and vegetables and reduced consumption of sweets) in both parents and children. However, the association in children is partially mediated by parents'' diet quality. The promotion of consuming meals together in the family could be a potentially effective strategy for interventions aiming to establish and maintain healthy food consumption patterns among children

Repositioning of the global epicentre of non-optimal cholesterol

High blood cholesterol is typically considered a feature of wealthy western countries(1,2). However, dietary and behavioural determinants of blood cholesterol are changing rapidly throughout the world(3) and countries are using lipid-lowering medications at varying rates. These changes can have distinct effects on the levels of high-density lipoprotein (HDL) cholesterol and non-HDL cholesterol, which have different effects on human health(4,5). However, the trends of HDL and non-HDL cholesterol levels over time have not been previously reported in a global analysis. Here we pooled 1,127 population-based studies that measured blood lipids in 102.6 million individuals aged 18 years and older to estimate trends from 1980 to 2018 in mean total, non-HDL and HDL cholesterol levels for 200 countries. Globally, there was little change in total or non-HDL cholesterol from 1980 to 2018. This was a net effect of increases in low- and middle-income countries, especially in east and southeast Asia, and decreases in high-income western countries, especially those in northwestern Europe, and in central and eastern Europe. As a result, countries with the highest level of non-HDL cholesterol-which is a marker of cardiovascular riskchanged from those in western Europe such as Belgium, Finland, Greenland, Iceland, Norway, Sweden, Switzerland and Malta in 1980 to those in Asia and the Pacific, such as Tokelau, Malaysia, The Philippines and Thailand. In 2017, high non-HDL cholesterol was responsible for an estimated 3.9 million (95% credible interval 3.7 million-4.2 million) worldwide deaths, half of which occurred in east, southeast and south Asia. The global repositioning of lipid-related risk, with non-optimal cholesterol shifting from a distinct feature of high-income countries in northwestern Europe, north America and Australasia to one that affects countries in east and southeast Asia and Oceania should motivate the use of population-based policies and personal interventions to improve nutrition and enhance access to treatment throughout the world.Peer reviewe

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

Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019: a pooled analysis of 1201 population-representative studies with 104 million participants.

BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blood pressure treatment. We defined hypertension as having systolic blood pressure 140 mm Hg or greater, diastolic blood pressure 90 mm Hg or greater, or taking medication for hypertension. We applied a Bayesian hierarchical model to estimate the prevalence of hypertension and the proportion of people with hypertension who had a previous diagnosis (detection), who were taking medication for hypertension (treatment), and whose hypertension was controlled to below 140/90 mm Hg (control). The model allowed for trends over time to be non-linear and to vary by age. FINDINGS: The number of people aged 30-79 years with hypertension doubled from 1990 to 2019, from 331 (95% credible interval 306-359) million women and 317 (292-344) million men in 1990 to 626 (584-668) million women and 652 (604-698) million men in 2019, despite stable global age-standardised prevalence. In 2019, age-standardised hypertension prevalence was lowest in Canada and Peru for both men and women; in Taiwan, South Korea, Japan, and some countries in western Europe including Switzerland, Spain, and the UK for women; and in several low-income and middle-income countries such as Eritrea, Bangladesh, Ethiopia, and Solomon Islands for men. Hypertension prevalence surpassed 50% for women in two countries and men in nine countries, in central and eastern Europe, central Asia, Oceania, and Latin America. Globally, 59% (55-62) of women and 49% (46-52) of men with hypertension reported a previous diagnosis of hypertension in 2019, and 47% (43-51) of women and 38% (35-41) of men were treated. Control rates among people with hypertension in 2019 were 23% (20-27) for women and 18% (16-21) for men. In 2019, treatment and control rates were highest in South Korea, Canada, and Iceland (treatment >70%; control >50%), followed by the USA, Costa Rica, Germany, Portugal, and Taiwan. Treatment rates were less than 25% for women and less than 20% for men in Nepal, Indonesia, and some countries in sub-Saharan Africa and Oceania. Control rates were below 10% for women and men in these countries and for men in some countries in north Africa, central and south Asia, and eastern Europe. Treatment and control rates have improved in most countries since 1990, but we found little change in most countries in sub-Saharan Africa and Oceania. Improvements were largest in high-income countries, central Europe, and some upper-middle-income and recently high-income countries including Costa Rica, Taiwan, Kazakhstan, South Africa, Brazil, Chile, Turkey, and Iran. INTERPRETATION: Improvements in the detection, treatment, and control of hypertension have varied substantially across countries, with some middle-income countries now outperforming most high-income nations. The dual approach of reducing hypertension prevalence through primary prevention and enhancing its treatment and control is achievable not only in high-income countries but also in low-income and middle-income settings.
