Ambient temperature exposure and rapid infant weight gain.

BACKGROUND: Childhood obesity is a major public health concern, and the global rate is rising. Rapid infant weight gain is a risk factor for later overweight. Studies have linked prenatal ambient temperature exposure to fetal growth, and preliminary evidence suggests postnatal exposure may be associated with infant weight gain. METHODS: Using a population-based historical cohort study including 1 100 576 infants born 2011-2019, we assessed the relationship between prenatal and one-month postnatal ambient temperature exposure and rapid infant weight gain. We used a hybrid spatiotemporal model to assess temperatures at the family's recorded residence at birth. Repeated weight measurements between birth and 15 months were used to model the outcome using the SuperImposition by Translation and Rotation (SITAR) method. We employed generalized linear models and distributed lag models to estimate the association between prenatal and postnatal exposure and rapid infant weight gain, defined as the upper tertile of the SITAR growth velocity. RESULTS: Overall, higher ambient temperatures were associated with rapid infant weight gain. The cumulative adjusted relative risk for the highest exposure quintile during pregnancy compared with the lowest quintile was 1.33 [95% confidence interval (CI): 1.25, 1.40], and the corresponding association for the first postnatal month was 1.19 (95% CI: 1.15, 1.23). Exposure to high ambient temperature during early and mid-pregnancy, as well as the first postnatal month, was associated with rapid weight gain, while during late pregnancy, exposure to low temperatures was associated with this outcome. CONCLUSIONS: Prenatal and postnatal ambient temperatures are associated with rapid infant weight gain.

Predictors of Overweight/Obesity Among Preschool Children in Arba Minch City, Southern Ethiopia: Does Consumption of Sweet Food Predispose to Overweight/Obesity?

Objectives: Childhood overweight/obesity is a serious public health problem in the world today specially low-and-middle income countries like Ethiopia. This study aimed to assess the prevalence of overweight/obesity and associated factors among preschool children. Methods: A community-based cross-sectional study was conducted among preschool children aged 3-5 years in Arba Minch city from April to June 2022. A multistage sampling method was used to select 577 study participants. Data were collected using a structured and pretested questionnaire. A binary logistic regression model was used for analysis. An adjusted odds ratio (AOR) with a 95% confidence interval (CI) was used to assess the strength of the association. Results: The combined prevalence of overweight/obesity was 23.9% (95% CI: 20.5, 27.6). Age of 36-47 months, family size < five, watching TV/video for ≥2 h, and consuming sweet foods, were factors associated with being overweight/obese among preschool children. Conclusion: Overweight/obesity was predicted by consuming sweet foods, long time TV/video watching, and large family size in the study area. Special attention should be given to child feeding practices and reducing sedentary lifestyles.

The association of plasma asprosin with anthropometric and metabolic parameters in Korean children and adolescents.

Background: This study aimed to determine the correlation of plasma asprosin with anthropometric and metabolic parameters in Korean children and adolescents. Methods: This single-center study included 109 Korean children and adolescents: 62 (56.9%) obese participants with a body mass index (BMI) ≥95th percentile and 47 (43.1%) healthy controls with BMI between the 15th and 85th percentile. Metabolic parameters were measured, including fasting blood glucose, fasting insulin, homeostasis model assessment of insulin resistance (HOMA-IR), triglyceride and glucose (TyG) index, and lipid profiles. Results: Plasma asprosin levels were higher in the obese group than in the control group (mean 87.0 vs. 69.3 ng/mL; p = 0.001) and in the IR group than in the non-IR group (mean 98.6 vs. 70.2 ng/mL; p < 0.001). Plasma asprosin levels were not associated with sex or pubertal stage. Plasma asprosin levels were positively correlated with BMI SDS (r = 0.34; p = 0.002), glycated hemoglobin (HbA1c) (r = 0.25; p = 0.02), glucose (r = 0.33; p = 0.002), insulin (r = 0.44; p < 0.001), HOMA-IR (r = 0.47; p < 0.001), triglyceride (TG) (r = 0.33; p = 0.003), high-density lipoprotein (HDL) cholesterol (r = -0.29; p = 0.008), and TyG index (r = 0.38; p < 0.001). Multiple linear regression analysis indicated that plasma asprosin levels were independently associated with HOMA-IR (p < 0.001) and TG/HDL cholesterol ratio (p < 0.001). Conclusions: This study demonstrated an association between plasma asprosin levels and obesity and insulin resistance in Korean children and adolescents.

Dietary Patterns by Level of Maternal Education and Their Contribution to BMI, Fat Mass Index, and Fat-Free Mass Index at Age 5 and the Longitudinal Association with BMI at Age 10.

BACKGROUND: Our aim was to identify dietary patterns by the level of maternal education that contribute to BMI, fat mass index (FMI), and fat-free mass index (FFMI) in children at age 5 and to assess if these dietary patterns are related to BMI at age 10. METHODS: Per group (low/middle/high level), Reduced Rank Regression (RRR) was used to derive dietary patterns for the response variables BMI z-score, FMI, and FFMI in 1728 children at age 5 in the Amsterdam Born Children and their Development (ABCD) cohort. Regression analyses were then used to determine the association with BMI at age 10. RESULTS: In each group, pattern 1 was characterized by its own cluster of food groups. Low: water/tea, savory snacks, sugar, low-fat meat, and fruits; middle: water/tea, low-fat cheese, fish, low-fat dairy, fruit drink, low-fat meat, and eggs; and high: low-fat cheese, fruits, whole-grain breakfast products, and low-fat and processed meat. Additionally, in each group, pattern 1 was positively associated with BMI z-scores at age 10 (low: ß ≤ 0.43 [95% CI ≤ 0.21; 0.66], p < 0.001, middle: ß ≤ 0.23 [0.09; 0.36], p ≤ 0.001, and high: ß ≤ 0.24 [0.18; 0.30], p < 0.001). CONCLUSIONS: The dietary patterns stratified by the level of maternal education are characterized by different food groups. But in all the groups, pattern 1 is positively associated with BMI at age 10.

Associations between Changes in Body Weight Status and High Blood Pressure among Lithuanian Children and Adolescents during the COVID-19 Pandemic: A Retrospective Cohort Study.

(1) Background: High blood pressure (HBP), overweight, and obesity are common, growing public health problems worldwide. The aim of this study was to evaluate associations between changes in body weight status and HBP among Lithuanian children and adolescents during the COVID-19 pandemic. (2) Methods: In this study, we analysed data on blood pressure and anthropometric measurements of 2430 children and adolescents aged 8-18 years, who participated in both the baseline study conducted before the COVID-19 pandemic (from November 2019 to March 2020) and the follow-up study during the COVID-19 pandemic (from November 2021 to April 2022). Multivariate logistic regression analysis was used to estimate the associations between changes in weight status categories and HBP. (3) Results: At baseline, 17.1% of the subjects had overweight, 5.9% had obesity, 5.6% had abdominal obesity, and 23.7% had HBP, whereas at the follow-up, these percentages increased to 20.1%, 8.2%, 6.8%, and 27.4%, respectively. Compared to schoolchildren who maintained normal weight from baseline to the follow-up period, subjects who newly developed overweight/obesity and those who remained with persistent overweight/obesity had increased odds of HBP, with adjusted odds ratios (aORs) of 1.95 (p < 0.001) and 2.58 (p < 0.001), respectively. In subjects who transitioned from overweight/obesity to normal weight, the odds of HBP were slightly increased, with an aOR of 1.14 (p = 0.598), but the change was not statistically significant (p > 0.05). (4) Conclusions: This study observed an increase in the prevalence of overweight, obesity, and HBP among schoolchildren during the COVID-19 pandemic. The study also suggested that changes from normal body weight status at baseline to overweight/obesity during follow-up, especially persistent overweight/obesity, were associated with higher odds of HBP in Lithuanian children and adolescents during the COVID-19 pandemic.

Dairy Consumption at Breakfast among Southeast Asian Children: Associations with Nutrient Intake from the South East Asian Nutrition Surveys II (SEANUTS II).

BACKGROUND: Children's rapid growth requires adequate nutrient intake, with breakfast, especially when incorporating dairy, playing an important role. This study examined associations between dairy consumption at breakfast and energy and nutrient intake among children in Southeast Asia. METHODS: Utilizing the cross-sectional South East Asian Nutrition Surveys II dataset, using a 24 h dietary recall and questionnaires distributed among 10,286 children aged 2 to 12 years from Malaysia, Thailand, Indonesia, and Vietnam, we investigated the impact of dairy consumption at breakfast on nutrient intake and examined associations between breakfast consumption and the prevalence of stunting and overweight/obesity among 10,135 children. RESULTS: Although most of the children consumed breakfast, only 37%, 27%, 16%, and 18% in Malaysia, Thailand, Indonesia, and Vietnam, respectively, included dairy in this meal, with younger children being significantly more likely to consume dairy at breakfast (p < 0.001). Dairy consumers had significantly higher intakes of vitamins A, B12, and D and calcium both at breakfast and throughout the day (p < 0.001). Breakfast skippers had a 29% increased risk of being overweight/obese. CONCLUSIONS: Dairy consumption at breakfast was associated with enhanced nutrient intake and overall diet quality among Southeast Asian children. The association between breakfast habits and anthropometric outcomes highlights the need to address nutritional deficiencies and promote healthy growth and development.

Cardiometabolic risk in children and adolescents with obesity: a position paper of the Italian Society for Pediatric Endocrinology and Diabetology.

Despite the implementation of preventive measures to counteract the obesity epidemics, the prevalence of childhood obesity is still alarming all over the world. Childhood obesity is the most common risk factor for both cardiovascular and metabolic diseases. In fact, an earlier onset of obesity can cause a greater risk of adiposity tracking across the lifespan and consequently a longer exposure to cardiometabolic risk factors. Accumulating evidence provided by prospective and intervention studies demonstrated the link between pediatric obesity and selected subclinical signs of cardiovascular damage (atherosclerosis and left ventricular hypertrophy), or fatal and not fatal cardiovascular events as early as 40 years of age.The numerous guidelines and scientific documents published in the last years demonstrate the relevance of assessing cardiometabolic risk factors in children and adolescents with OB.This Position paper, released by experts of the "Childhood Obesity study group" within the Italian Society for Pediatric Endocrinology and Diabetology, aims to review the assessment of cardiometabolic risk factors and comorbidities in children and adolescents with OW/OB on the light of the most recent scientific evidence.The main recommendations are: (a) early detection of comorbidities, including hypertension, dyslipidemia, prediabetes/type 2 diabetes, metabolic dysfunction-associated steatotic liver disease, polycystic ovary syndrome, inactivity, obstructive sleep apnea and decline in kidney function; (b) weight loss treatment, which is associated with a reduction of all cardiometabolic risk factors; (c) specific treatment of comorbidities, through lifestyle modifications or pharmacological treatment added to lifestyle for suitable individuals; d). monitoring comorbidities for mitigating future morbidity and mortality.

Mediterranean diet adherence in 9-years old children: a cross-sectional study in the part of the Split-Dalmatia County, Croatia.

OBJECTIVES: Childhood obesity is a growing global problem that can be prevented by improving diet quality. Mediterranean diet (MedDiet), historically present in Mediterranean countries, is considered one of the healthiest dietary patterns. This cross-sectional study aimed to determine the MedDiet adherence and anthropometric parameters in 9-year-old children from the central geographic locations of Split-Dalmatia County, Croatia. METHODS: The study analysed data obtained from 158 children aged nine years from central parts of Dalmatia: Split and Hvar. To assess the MedDiet adherence, the parents of the children filled out the Mediterranean Diet Index (KIDMED) questionnaire. Appointed school medicine specialists collected anthropometric data of the children and categorized them into body mass index (BMI) categories according to the Center for Disease Control and Prevention (CDC) criteria. Additionally, we assessed the influence of parents' education degree on children's MedDiet adherence and anthropometric measures. RESULTS: Results showed that more than a quarter of nine-year-olds included in this study were overweight or obese (BMI ≥ 85th percentile for age and sex). One of the main findings was that 72% of children had suboptimal (poor or average) MedDiet adherence. Moreover, children with suboptimal KIDMED results (KI < 8) had significantly higher body weight, waist circumference, hip circumference, and waist-to-height ratio. Also, results showed that mothers' education notably influences children's anthropometry. CONCLUSION: Our study found that childhood obesity is a significant concern among 9-year-olds, with a high prevalence of overweight and obesity. Additionally, our results showed that MedDiet adherence is suboptimal among this age group. These results indicate that children of the Mediterranean are not spared of modern life challenges. This problem should be prioritized in the future to prevent the development of a metabolically compromised adult population.

Screen time, sleep duration, leisure physical activity, obesity, and cardiometabolic risk in children and adolescents: a cross-lagged 2-year study.

BACKGROUND: Considering the previous research that suggested that screen time (ST), sleep duration, physical activity (PA), obesity and cardiometabolic risk factors are related, it is essential to identify how these variables are associated over time, to provide knowledge for the development of intervention strategies to promote health in pediatric populations. Also, there is a lack of studies examining these associations longitudinally. The aims of the present study were: (1) to investigate the longitudinal relationships between ST, sleep duration, leisure PA, body mass index (BMI), and cardiometabolic risk score (cMetS) in children and adolescents; and (2) to verify scores and prevalence of cMetS risk zones at baseline and follow-up. METHODS: This observational longitudinal study included 331 children and adolescents (aged six to 17 years; girls = 57.7%) from schools in a southern city in Brazil. ST, sleep duration, and leisure PA were evaluated by a self-reported questionnaire. BMI was evaluated using the BMI z-scores (Z_BMI). The cMetS was determined by summing sex- and age-specific z-scores of total cholesterol/high-density lipoprotein cholesterol (HDL-C) ratio, triglycerides, glucose, and systolic blood pressure and dividing it by four. A two-wave cross-lagged model was implemented. RESULTS: ST, sleep duration, and leisure PA were not associated with cMetS after 2-years. However, it was observed that higher ST at baseline was associated with shorter sleep duration at follow-up (B=-0.074; 95%IC=-0.130; -0.012), while higher Z_BMI from baseline associated with higher cMetS of follow-up (B = 0.154; 95%CI = 0.083;0.226). The reciprocal model of relationships indicated that the variance of ST, sleep time, leisure PA, Z_BMI, and cMetS explained approximately 9%, 14%, 10%, 67% and 22%, respectively, of the model. Individual change scores and prevalence indicated that cMetS had individual changes from 2014 to 2016. CONCLUSION: Sleep duration, ST and leisure PA were not associated with cMetS after 2 years. ST showed an inverse association with sleep duration, and Z_BMI was positively associated with cMetS after a 2-year follow-up. Finally, the prevalence of no clustering of risk factors increased after two years. These findings suggest the need to promote healthy lifestyle habits from childhood and considering individual factors that can influence cardiometabolic health in children and adolescents.

Occurrence of overweight, obesity and their associated risk factors among primary school pupils in Samarra/Iraq: a cross-sectional study.

OBJECTIVE: To find the prevalence of overweight and obesity and the risk factors for increasing weight among young students. METHODS: The cross-sectional, descriptive study was conducted during the 2018-19 academic year in Samarra, Iraq, after approval from the ethics review committee of Anbar University, Al Anbar, Iraq, and comprised primary schoolchildren aged 7-13 years regardless of gender. After collecting sociodemographic data, based on body mass index values, the children were categorised into malnourished <5th percentile, normal 5-84th percentile, overweight 85-97th percentile, and obese ≥97th percentile. Data was analysed using SPSS 27. RESULTS: Of the 450 subjects, 243(54%) were girls and 207(46%) were boys. Obesity was found in 54(12%,) subjects, while 83(18.4%) were overweight. Class grades of the schoolchildren, mothers' education, type of food taken to school, money to buy from the school canteen, consumption of soft drinks, and eating snacks were significantly related to body mass index percentile (p<0.05). CONCLUSIONS: Overweight and obesity were prevalent in school children, and a number of factors contributed to the problem, highlighting the need for health education interventions.

Influence of eating while watching TV on food preference and overweight/obesity among adolescents in China: a longitudinal study.

Background: Eating while watching TV was found associated with unhealthy food preferences and obesity in adolescents in foreign studies, which is not clear in China. The study aims to explore the influence of eating while watching TV on food preferences and overweight/obesity in Chinese adolescents. Methods: Data from 1768 adolescents (aged 12-17 years) in the 2006, 2009, 2011, and 2015 China Health and Nutrition Survey (CHNS) was analyzed. The height and weight were measured. Mixed effect models were used to identify the associations between eating while watching TV and adolescents' food preferences and overweight/obesity. Results: Adolescents eating while watching TV ≥1 time/week were more likely to prefer fast food, salty snacks and soft drinks than those eating while watching TV <1 time/week. Adolescents eating meals while watching TV ≥1 time/week were less likely to prefer vegetables than those eating meals while watching TV <1 time/week. In addition, adolescents eating snacks while watching TV ≥1 time/week were more likely to be overweight/obesity than those eating meals while watching TV <1 time/week (odds ratio [OR] = 7.16; 95% confidence interval [CI] 1.39-36.93). Conclusion: Eating snacks while watching TV was positively associated with adolescents' unhealthy food preferences and overweight/obesity. Eating meals while watching TV was associated with adolescents' unhealthy food preferences. Implementing web-based Community-based participatory research (CBPR) about reducing eating while watching TV may be a practical strategy to develop healthy food preferences and prevent overweight/obesity in Chinese adolescents.

Quantifying the effect of interpregnancy maternal weight and smoking status changes on childhood overweight and obesity in a UK population-based cohort.

BACKGROUND: Maternal preconception and pregnancy exposures have been linked to offspring adiposity. We aimed to quantify the effect of changes in maternal weight and smoking status between pregnancies on childhood overweight/obesity (≥ 85th centile) and obesity (≥ 95th centile) rates in second children. METHODS: Records for 5612 women were drawn from a population-based cohort of routinely collected antenatal healthcare records (2003-2014) linked to measured child body mass index (BMI) age 4-5 years. We applied the parametric G-formula to estimate the effect of hypothetical changes between pregnancy-1 and pregnancy-2 compared to the natural course scenario (without change) on child-2 BMI. RESULTS: Observed overweight/obesity and obesity in child-2 at age 4-5 years were 22.2% and 8·5%, respectively. We estimated that if all mothers started pregnancy-2 with BMI 18·5-24·9 kg/m² and all smokers stopped smoking, then child-2 overweight/obesity and obesity natural course estimates of 22.3% (95% CI 21.2-23.5) and 8·3% (7·6-9·1), would be reduced to 18.5% (17.4-19.9) and 6.2% (5.5-7.0), respectively. For mothers who started pregnancy-1 with BMI 18·5-24·9 kg/m², if all smokers stopped smoking, child-2 overweight/obesity and obesity natural course estimates of 17.3% (16.0-18.6) and 5·9% (5·0-6·7) would be reduced to 16.0% (14.6-17.3) and 4·9% (4·1-5·7), respectively. For mothers who started pregnancy-1 with BMI ≥30 kg/m², if BMI was 18·5-24·9 kg/m² prior to pregnancy-2, child-2 overweight/obesity and obesity natural course estimates of 38.6% (34.7-42.3) and 17·7% (15·1-20·9) would be reduced to 31.3% (23.8-40.0) and 12.5 (8.3-17.4), respectively. If BMI was 25.0-29.9 kg/m² prior to pregnancy-2, these estimates would be 34.5% (29.4-40.4) and 14.6% (11.2-17.8), respectively. CONCLUSION: Interventions supporting women to lose/maintain weight and quit smoking between pregnancies could help reduce rates of overweight/obesity and obesity in second children. The most effective interventions may vary by maternal BMI prior to the first pregnancy.

Spatial variations and predictors of overweight/obesity among under-five children in Ethiopia: A geographically weighted regression analysis of the 2019 Ethiopian Mini Demographic and Health Survey.

BACKGROUND: Overweight/ obesity among under-five children is an emerging public health issue of the twenty-first century. Due to the quick nutritional and epidemiological change, non-communicable diseases, premature death, disability, and reproductive disorders have grown in low-income countries. Besides, little attention has been given. Therefore, we aimed to explore spatial variations and predictors of overweight/obesity among under-five children in Ethiopia using a geospatial technique. METHODS: A total weighted sample of 3,609 under-five children was included in the study. A cross-sectional study was conducted using a nationally representative sample of the 2019 Ethiopia Mini Demographic and Health Survey data set. ArcGIS version 10.8 was used to explore the spatial variation of obesity. SaTScan version 9.6 software was used to analyze the spatial cluster detection of overweight/obesity. Ordinary least square and geographically weighted regression analysis were employed to assess the association between an outcome variable and explanatory variables. A p-value of less than 0.05 was used to declare it statistically significant. RESULTS: The spatial distribution of overweight/obesity among under-five children in Ethiopia was clustered (Global Moran's I = 0.27, p-value<0.001). The significant hot spot areas or higher rates of childhood obesity, were found in Southern Amhara, Northwest Somalia, Border of Harari, central Addis Ababa, Eastern SNNPR, and Northwestern Oromia region. In spatial SaT Scan analysis, 79 significant clusters of overweight/obesity were detected. The primary clusters were located in SNNPR, Oromia, and Addis Ababa (RR = 1.48, LLR = 31.40, P-value < 0.001). In the geographically weighted regression analysis, urban residence, cesarean section, rich households, and female children were statistically significant predictors. CONCLUSIONS: Overweight or obesity among under-five children show spatial variations across Ethiopian regions. GWR analysis identifies cesarean section, wealth index, urban residence, and child sex as significant predictors. The Ministry of Health and Ethiopian Public Health Institute should target regions with these contributing predictors, promoting localized physical education, health education campaigns, and ongoing community monitoring to encourage active lifestyles and reduce sedentary behaviors among children.

Changes in BMI prior to and during the COVID-19 pandemic among children: a retrospective cohort study in San Francisco, CA.

BACKGROUND: The COVID-19 pandemic led to dramatic changes in the lives of children that impact cardiometabolic health. Cities and counties had varying policies with respect to school closure, recreational programs, and efforts to mitigate food insecurity and economic distress. Our objective was to evaluate changes in BMI-z score and prevalence of overweight/obesity prior to and during the pandemic among children in San Francisco, CA, where public schools were closed for 18-months. METHODS: This was an electronic medical record-based retrospective cohort study. We included 15,401 children, 4-17 years of age at study onset. Our exposure was time into each of three time periods: (1) March 2018-February 2019; (2) March 2019-February 2020; (3) March 2020-August 2021 (the pandemic period of school closure). Generalized estimating equations (GEE) were used to assess changes in BMI-z score and overweight/obesity across the three time periods. We assessed for effect modification by age-category, insurance status, and race/ethnicity. RESULTS: Mean BMI-z score increased by 0.06 per year in time period 2, the year prior to the pandemic (p < 0.001, 95% CI: 0.04, 0.09), and by 0.12 per year during time period 3, the first 18 months of the pandemic (p < 0.001, 95% CI 0.10, 0.13). The proportion of children with overweight/obesity increased by 1.4% points per year during time period 2 (p = 0.012, 95% CI: 0.03, 2.46) and by 4.9% points per year during the first 18 months of the pandemic (p < 0.001, 95% CI: 4.11, 5.67). The effect modification analysis demonstrated that the youngest age group, publicly insured children (versus privately insured), and Black, Latino, and Asian children (versus White children) experienced greater increases in BMI-z score during the pandemic (p < 0.01 for all comparisons). The youngest age group (p = 0.022) and publicly insured children (versus privately insured children) (p < 0.001) also experienced greater increases in the proportion of children with overweight/obesity during the pandemic. CONCLUSIONS: Among children in San Francisco, increases in BMI-z score and overweight/obesity were greater during the pandemic compared to prior changes, with the most pronounced increases among younger and publicly insured children. These findings support the need for more targeted and effective policies for addressing childhood overweight/obesity, especially among these high-risk populations.

The global death and disability burden associated with a high BMI in children and adolescents, 1990-2019.

Objective: Exploring changing trends in the burden caused by overweight and obesity among children and adolescents from 1990 to 2019 at the global, regional, and national levels, based on data from the Global Burden of Disease study (GBD) 2019. Methods: The annual number and rate of deaths and disability-adjusted life years (DALYs) associated with a high BMI among children and adolescents at global, regional, and national levels by age groups, sexes, and the sociodemographic index from 1990 to 2019 were collected from the GBD study 2019. Change percentage for number, and the estimated annual percentage changes (EAPCs) for rate were calculated to determine the temporal trends. Results: From 1990 to 2019, global high BMI-related deaths decreased by 34% but DALYs increased by 48%. Death rates in females were higher than in males, although both showed decreasing trends. For the rate of DALYs, both sexes showed increasing trends, but since 1999, the rate in males has surpassed that in females. A high BMI had the greatest impact on children under 5 years of age, and the burden in other age groups continued to increase. Regionally, High-income Asia Pacific experienced the fastest decrease in death rate (EAPC=-9.57), and East Asia saw the fastest increase in the DALYs rate (EAPC= 3.47). Globally, as age increases, the proportion of disease burden attributed to a high BMI in females generally increases. Conclusions: Our findings emphasize the urgent need to improve efforts to prevent children and adolescents becoming overweight and obese.

OPTIMISING THE CLINICAL ASSESSMENT OF CHILDHOOD AND ADOLESCENT OBESITY IN JORDAN.

Clinical practice guidelines aim to facilitate early diagnosis, implement early treatment and minimise gaps in care regardless of physician expertise or level of seniority. Consensus guidelines must be adapted to meet local and regional differences allowing for optimum benefit with what is available in terms of diagnostics and treatments. Childhood and adolescent obesity are no exception to this. In this survey we aim to understand practice variation and gaps to better advocate for a regional and local care plan for obesity care in the young. METHODS: A questionnaire was conducted between July 2024 and August 2024, aimed at healthcare professionals of all medical specialties. It consisted of 104 questions. RESULTS: Family medicine consultants treat most obese youth in Jordan. Several gaps were identified in the assessment and care of patients, including but not limited to psychosocial effects of obesity and efficient multidisciplinary teamwork. CONCLUSION: Clear consensus guidelines are necessary to tackle childhood and adolescent obesity in Jordan.

Economic benefits of reducing childhood and adolescent overweight and obesity in Australia.

OBJECTIVES: The Australian Government, through the National Obesity Strategy 2022-2032, has set an aspirational goal of reducing the prevalence of childhood and adolescent overweight and obesity by 5% by 2030 (from 25% to 20%). Our objective was to quantify the long-term economic benefits of achieving this goal. METHODS: Using a microsimulation model and a synthetic cohort of Australian children and adolescents aged 4-17 years, we estimated the excess per capita lifetime costs of overweight and obesity. Using these results and population projections for 2030, we estimated the potential lifetime cost savings that could be achieved through attaining the National Obesity Strategy goal. RESULTS: Compared with their peers of a healthy weight, children and adolescents with overweight and obesity were estimated to incur, per capita, excess lifetime costs (discounted) of approximately $19 700 and $46 700, respectively (in 2030 Australian dollars). Achieving the National Obesity Strategy's goal was estimated to save approximately $7.44 billion, predominantly through reductions in lifetime obesity-related healthcare costs and premature mortality. CONCLUSION: Our results demonstrate the considerable economic benefits that could be achieved by reducing the current prevalence of childhood and adolescent overweight and obesity in Australia; they provide justification for investment in prevention and treatment for this demographic.

Adolescent Metabolic Screening.

This article explores metabolic syndrome (MetS) in children and adolescents, shedding light on its significant influence on long-term cardiovascular health outcomes. We navigate the complex landscape of MetS, where there is no universally accepted definition, and explore its roots in factors like obesity and insulin resistance. We also discuss the challenges of diagnosing and understanding its relevance in pediatric populations. The article also discussed the impact of the COVID-19 pandemic on the metabolic well-being of adolescents. Also, we discuss the importance of addressing associated comorbidities and risk factors in the context of MetS.

Rationale and design of Healthy Kids Beyond the Bell: a 2x2 full factorial study evaluating the impact of summer and after-school programming on children's body mass index and health behaviors.

BACKGROUND: The Structured Days Hypothesis posits that structure protects children against obesogenic behaviors (e.g., physical inactivity, unhealthy dietary intake) and, ultimately, prevents the occurrence of excessive weight gain. The hours following school (i.e., 3-6 pm school days) and summer vacation are two "windows of vulnerability" when children may experience less structure. Programs that provide a healthy structured environment and may prevent BMI gain exist for both time periods (i.e., after-school programs and summer day camps). Unfortunately, these programs are cost prohibitive for children from low-income families to attend. This study will test the impact of providing vouchers to access existing, community-operated after-school and summer programs on BMI z-score, body composition, and obesogenic behaviors (i.e., physical activity, screen use, diet, and sleep) of children (5-12 years) from schools that primarily serve families with low income. METHODS: The study will employ a 2x2 factorial design. Participants (N = 480) attending 4 elementary schools in one school district will be randomly assigned to a no treatment control, after-school program voucher only, summer day camp voucher only, or after-school and summer day camp vouchers. Vouchers will cover the full cost of attending a pre-existing community-based after-school or summer camp program. The primary outcome (BMI z-score) will be measured at baseline (before end of school year, ~ May), 3-month follow-up (after summer, ~ August), and 12-month follow-up (end the following school year, ~ May). Secondary outcomes include body composition (i.e., whole-body fat mass, fat free mass, and percent body fat) and obesogenic behaviors (i.e., physical activity, sedentary time, sleep, screen-time, and diet). The study will also employ a rigorous process evaluation which will consider after-school and summer camp program attendance and content. Analyses will examine differences between the four groups in BMI z-score, body composition, and obesogenic behaviors. Incremental cost effectiveness ratios will determine the cost effectiveness of the intervention. DISCUSSION: The current study will provide critical information for researchers, practitioners, and policy makers seeking to combat the childhood obesity epidemic in children from families with low-income during the school year and summer.
