Associations of longitudinal BMI percentile classification patterns in early childhood with neighborhood-level social determinants of health.

Understanding social determinants of health (SDOH) that may be risk factors for childhood obesity is important to developing targeted interventions to prevent obesity. Prior studies have examined these risk factors, mostly examining obesity as a static outcome variable. We extracted EHR data from 2012-2019 for a children's health system that includes 2 hospitals and wide network of outpatient clinics spanning 5 East Coast states in the US. Using data-driven and algorithmic clustering, we have identified distinct BMI-percentile classification groups in children from 0 to 7 years of age. We used two separate algorithmic clustering methods to confirm the robustness of the identified clusters. We used multinomial logistic regression to examine the associations between clusters and 27 neighborhood SDOHs and compared positive and negative SDOH characteristics separately. From the cohort of 36,910 children, five BMI-percentile classification groups emerged: always having obesity (n=429; 1.16%), overweight most of the time (n=15,006; 40.65%), increasing BMI-percentile (n=9,060; 24.54%), decreasing BMI-percentile (n=5,058; 13.70%), and always normal weight (n=7,357; 19.89%). Compared to children in the decreasing BMI-percentile and always normal weight groups, children in the other three groups were more likely to live in neighborhoods with higher poverty, unemployment, crowded households, single-parent households, and lower preschool enrollment. Neighborhood-level SDOH factors have significant associations with children's BMI-percentile classification and changes in classification. This highlights the need to develop tailored obesity interventions for different groups to address the barriers faced by communities that can impact the weight and health of children living within them. This study demonstrates the association between longitudinal BMI-percentile patterns and SDOH in early childhood. Five distinct clusters with different BMI-percentile trajectories are found and a strong association between these clusters and SDOH is observed. Our findings highlight the importance of targeted prevention and treatment interventions based on children's SDOH.

Pediatric Lipid Screening Prevalence Using Nationwide Electronic Medical Records

Universal screening to identify unfavorable lipid levels is recommended for US children aged 9 to 11 years and adolescents aged 17 to 21 years (hereafter, young adults); however, screening benefits in these individuals have been questioned. Current use of lipid screening and prevalence of elevated lipid measurements among US youths is not well understood. To investigate the prevalence of ambulatory pediatric lipid screening and elevated or abnormal lipid measurements among US screened youths by patient characteristic and test type. This cross-sectional study used data from the IQVIA Ambulatory Electronic Medical Record database and included youths aged 9 to 21 years with 1 or more valid measurement of height and weight during the observation period (2018-2021). Body mass index (BMI) was calculated and categorized using standard pediatric BMI percentiles (9-19 years) and adult BMI categories (≥20 years). The data were analyzed from October 6, 2022, to January 18, 2023. Lipid measurements were defined as abnormal if 1 or more of the following test results was identified: total cholesterol (≥200 mg/dL), low-density lipoprotein cholesterol (≥130 mg/dL), very low-density lipoprotein cholesterol (≥31 mg/dL), non-high-density lipoprotein cholesterol (≥145 mg/dL), and triglycerides (≥100 mg/dL for children aged 9 years or ≥130 mg/dL for patients aged 10-21 years). After adjustment for age group, sex, race and ethnicity, and BMI category, adjusted prevalence ratios (aPRs) and 95% CIs were calculated. Among 3 226 002 youths (23.9% aged 9-11 years, 34.8% aged 12-16 years, and 41.3% aged 17-21 years; 1 723 292 females [53.4%]; 60.0% White patients, 9.5% Black patients, and 2.4% Asian patients), 11.3% had 1 or more documented lipid screening tests. The frequency of lipid screening increased by age group (9-11 years, 9.0%; 12-16 years, 11.1%; 17-21 years, 12.9%) and BMI category (range, 9.2% [healthy weight] to 21.9% [severe obesity]). Among those screened, 30.2% had abnormal lipid levels. Compared with youths with a healthy weight, prevalence of an abnormal result was higher among those with overweight (aPR, 1.58; 95% CI, 1.56-1.61), moderate obesity (aPR, 2.16; 95% CI, 2.14-2.19), and severe obesity (aPR, 2.53; 95% CI, 2.50-2.57). In this cross-sectional study of prevalence of lipid screening among US youths aged 9 to 21 years, approximately 1 in 10 were screened. Among them, abnormal lipid levels were identified in 1 in 3 youths overall and 1 in 2 youths with severe obesity. Health care professionals should consider implementing lipid screening among children aged 9 to 11 years, young adults aged 17 to 21 years, and all youths at high cardiovascular risk.

Progranulin and Vaspin as Potential Novel Markers in the Etiology of Type 1 Diabetes in Children.

Background and Objectives: Diabetes is a significant health problem, prompting the search for new therapeutic strategies. Recently, researchers have focused on identifying novel markers for the progression of this condition. It is well established that adipokines, such as progranulin and vaspin, play crucial roles in regulating lipid and carbohydrate metabolism. Materials and Methods: This single-center cross-sectional study aimed to assess serum progranulin and vaspin levels in 80 children diagnosed with type 1 diabetes (T1D) and to examine their correlation with body mass index (BMI), glycated hemoglobin, and lipid profile. The cohort included 40 children newly diagnosed with diabetes, 40 children with long-term diabetes (20 well-controlled and 20 poorly controlled), and 14 non-diabetic children as a control group. Progranulin and vaspin levels were determined using a sandwich enzyme-linked immunosorbent assay. Results: There were no significant differences in the progranulin and vaspin concentrations in the studied groups (p = 0.246 and p = 0.095, respectively). No statistically significant differences were noted in the levels of both adipokines among boys and girls within the T1D, well-controlled T1D, and poorly controlled T1D groups. We did not find any differences in the progranulin and vaspin levels among all children with T1D and healthy controls when divided based on BMI percentiles. A negative correlation was observed between progranulin concentration and the age of children in the T1D, well-controlled T1D, and healthy groups. Furthermore, progranulin correlated negatively with BMI among children with T1D. In contrast, vaspin concentration correlated positively with age among healthy children. Conclusions: Our study provides novel insights into the status of progranulin and vaspin among pediatric participants with varying levels of type 1 diabetes control. However, further research involving larger patient cohorts and different stages of sexual maturation is warranted.

Anthropometry for predicting cardiometabolic disease risk factors in adolescents.

Early screening prevents chronic diseases by identifying at-risk adolescents through anthropometric measurements, but predictive value in diverse groups is uncertain. A cross-sectional analysis of 12- to 19-year-old individuals from the 2017-2018 National Health and Nutrition Examination Survey (NHANES) assessed the predictive ability of BMI percentile, total body fat percentage, waist circumference (WC), and waist-hip ratio (WHR) for four cardiometabolic risk factors across race and ethnicity groups using receiver operating characteristic curves. The unweighted sample (N = 1194; 51.2% male individuals; 23.7% Hispanic, 13.2% non-Hispanic Black [NHB], 51.1% non-Hispanic White [NHW], 12.0% other/multirace) had a weighted prevalence of elevated blood pressure of 2.7%, hyperglycemia of 36.8%, hypertriglyceridemia of 4.8%, and low high-density lipoprotein (HDL) cholesterol of 15%. WHR (area under the curve [AUC] = 0.77), WC (AUC = 0.77), and BMI percentile (AUC = 0.73) outperformed total body fat percentage (AUC = 0.56) in predicting elevated blood pressure (p < 0.001 for all). BMI percentile was more accurate than total body fat percentage in predicting hypertriglyceridemia (AUC = 0.70 vs. 0.59; p = 0.02) and low HDL cholesterol (AUC = 0.69 vs. 0.59; p < 0.001). Race and ethnicity-based predictions varied: NHW adolescents had the highest AUC (0.89; p < 0.01) for elevated blood pressure prediction compared with Hispanic and NHB adolescents (AUC = 0.77 for both). Total body fat percentage was more accurate in predicting low HDL cholesterol among Hispanic versus NHW adolescents (AUC = 0.73 vs. 0.58; p = 0.04). WHR, WC, and BMI percentile are better predictors of cardiometabolic risk factors in adolescents than total body fat percentage. Predictive abilities differed by race and ethnicity, highlighting the importance of tailored risk assessment strategies.

Skin and macular carotenoids and relations to academic achievement among school-aged children

ABSTRACT Objectives: Carotenoids are plant pigments that accumulate in human tissue (e.g. macula and skin) and can serve as biomarkers for diet quality; however, knowledge on skin and macular carotenoids in relation to cognition in children is limited. This study aimed to address this gap by assessing links between skin and macular carotenoids and academic achievement in school-aged children. Methods: Children 7-12 years old (n = 81) participated in a crosssectional study. Skin and macular carotenoids were measured with reflection spectroscopy and heterochromatic flicker photometry, respectively. Academic achievement was measured using Woodcock-Johnson IV (WJ-IV). Body Mass Index was calculated using height and weight measurements, demographic information was collected using a family demographics and pediatric health history questionnaire, and carotenoid intake was assessed using 7-day diet records. Results: Skin carotenoids were not related to macular pigment (r = 0.08, p = 0.22). Adjusting for age, sex, BMI percentile, household income, and total carotenoid consumption (mg/1000kcal), skin carotenoids were predictive of math (β = 0.27, p = 0.02), broad math (β = 0.36, p < 0.01) and math calculation (β = 0.38, p < 0.01). Skin carotenoids displayed trending relationships with broad reading (β = 0.23, p = 0.05) and reading fluency (β = 0.22, p = 0.07). There were no significant associations between macular pigment and academic achievement (all β's ≤ 0.07, all p's ≥ 0.56). Discussion: Skin carotenoids were positively associated with academic abilities in children, while macular carotenoids did not display this relationship. Future interventions examining prospective effects of changes in carotenoids in different tissues on childhood academic achievement are warranted.

Dental-nutrition counseling for children with overweight and obesity: Evidence from a pilot study.

Given the relationship between overweight and obesity (OV/OB) and poor oral health in children, paediatric dentists are uniquely positioned to provide educational interventions to children with OV/OB during dental visits. To assess how an educational nutrition intervention delivered by dentists affected dental-nutritional behaviors and body mass index (BMI) percentile in children with OV/OB. Retrospective analysis was performed using data collected on 217 patients with OV/OB aged 6-11 years who received nutritional counseling during dental visits at a Federally Qualified Health Center from September 1, 2021, through September 30, 2022. Data were collected on sociodemographic variables, oral health, and BMI percentile. Participants and their guardians were surveyed to measure the frequency of behaviors related to oral health and weight. Multivariable generalized estimating equations were constructed to determine the effect of the intervention on BMI percentile and reported dental-nutritional behaviors. The intervention had no effect on the BMI percentile (p = .35). There were statistically significant reductions in the reported average number of sugar-sweetened beverages consumed daily (p < .001), reported average daily water intake (p < .001), and the reported frequency of brushing teeth (p < .001), the clinical significance of these reductions remains unclear. Further research is needed to establish the efficacy of behavioral interventions at reducing weight and changing health behaviors.

Characterizing Enoxaparin's Population Pharmacokinetics to Guide Dose Individualization in the Pediatric Population.

Pediatric dosing of enoxaparin was derived based on extrapolation of the adult therapeutic range to children. However, a large fraction of children do not achieve therapeutic anticoagulation with initial dosing. We aim to use real-world anti-Xa data obtained from children receiving enoxaparin per standard of care to characterize the population pharmacokinetics (PopPK).Author names: Please confirm if the author names are presented accurately and in the correct sequence (given name, middle name/initial, family name). Also, kindly confirm the details in the metadata are correct.The author names are accurately presented and the metadata are correct. METHODS: A PopPK analysis was performed using NONMEM, and a stepwise covariate modeling approach was applied for the covariate selection. The final PopPK model, developed with data from 1293 patients ranging in age from 1 day to 18 years, was used to simulate enoxaparin subcutaneous dosing for prophylaxis and treatment based on total body weight (0-18 years, TBW) or fat-free mass (2-18 years, FFM). Simulated exposures in children with obesity (body mass index percentile ≥95th percentile) were compared with those without obesity. A linear, one-compartment PopPK model that included allometric scaling using TBW (<2 years) or FFM (≥2 years) characterized the enoxaparin pharmacokinetic data. In addition, serum creatinine was identified as a significant covariate influencing clearance. Simulations indicated that in patients aged <2 years, the recommended 1.5 mg/kg TBW-based dosing achieves therapeutic simulated concentrations. In pediatric patients aged ≥2 years, the recommended 1.0 mg/kg dose resulted in exposures more comparable in children with and without obesity when FFM weight-based dosing was applied. Using real-world data and PopPK modeling, enoxaparin's pharmacokinetics were characterized in pediatric patients. Using FFM and twice-daily dosing might reduce the risk of overdosing, especially in children with obesity.

Growth charts for children aged 6–17 years in Shanxi, China: comparison with other cities of China and WHO

BackgroundGrowth charts are an important method for evaluating a child’s health, growth, and nutritional status. It is essential to monitor the growth of children and adolescents using growth charts.ObjectivesTo present body mass index (BMI)-for-age references reflecting children’s growth in Shanxi. We also compare our new data with growth references of other cities of China and World Health Organization (WHO) growth standards.MethodsA stratified cluster random sampling method was used to recruit 5461 children and adolescents aged 6–17 years. Height and weight were measured and BMI was calculated. The LMS method was used to calculate the percentile values of body mass index by sex and age. Smoothed BMI-for-age growth curves were presented for both sexes and compared with reference data from other cities of China and WHO.ResultsBMI centiles increased with age but with different patterns in both boys and girls. The centile curves from the 3rd to the 50th had a slight increase, while a sharp increase was seen from 11 to 17 years in boys and from 6 to 14 years in girls in the higher centiles. In comparison with other cities of China, the values for the 50th percentile are higher than those reported for children from China 2009, Shanghai, Changsha and China 2010 in both sexes. In comparison with WHO growth references, Chinese girls and boys had higher values in all percentiles, whereas curves of girls look roughly the same. The medians for BMI in Shanxi increase linearly from 6 to 17 years in boys.ConclusionsThe BMI percentiles of children aged 6–17 years in Shanxi differed significantly from the growth reference curves of other cities of China and WHO. Recommending the provision of BMI reference curves for local children and adolescents to assess their growth and development and monitor their nutritional status.Early detection of overweight and obesity in children provides a scientific basis for the prevention and control of overweight and obesity in children.

The Effect of Universal Free School Meals on Child BMI

Abstract We estimate the effect of universal free school meal access through the Community Eligibility Program (CEP) on child body mass index (BMI). Through the CEP, schools with high percentages of students qualified for free or reduced-priced meals can offer free breakfast and lunch to all students. With administrative data from a large school district in Georgia, we use student-level BMI measures from the FitnessGram to compare within-student outcomes before and after CEP implementation across eligible and non-eligible schools. We find one year of CEP exposure increased expected BMI percentile by about 0.085 standard deviation, equivalent to a nearly 1.88-pound weight increase for a student of average height. We also find that the program led to a small increase in the likelihood of overweight and limited evidence of a small decrease in the likelihood of underweight. We do not find that the program increased student obesity risk. Examining the effects of CEP on child BMI by grade suggests that the overall effect is largely driven by students in middle schools, highlighting potential heterogeneity in the program's impact across grades. The findings of this paper are relevant for researchers and policy makers concerned with the effects of universal free school meals on student health.

Breastfeeding Duration Reduces the Risk of Childhood Leukemia and Modifies the Risk of Developing Functional Gastrointestinal Disorders.

Objective: The aim of this study was to test the hypothesis that the duration of breastfeeding in infancy reduces the risk of childhood leukemia or lymphoma, and modifies the risk of developing functional gastrointestinal disorders (FGIDs). Subjects and Methods: This case-control study involved the recruitment of children with lymphoid malignancy and functional gastrointestinal symptoms with healthy children as controls. Focused questionnaires were used to collect data on breastfeeding history and other key risk factors. Univariate and multivariate analyses were undertaken. Results: Of the 334 children with lymphoid malignancy, 65% were male. The control group included 334 age- and sex-matched participants. Most (n = 189; 56.6%) of the children with leukemia were <10 years of age. Differences between cases and controls included the duration of breastfeeding (p < 0.0001), mean birthweight (p < 0.001), maternal age (p < 0.001), paternal age (p < 0.001), birth order (p < 0.001), mean number of children (p < 0.001), BMI percentile (p = 0.042), and maternal smoking (p = 0.012). Breastfeeding duration of up to 6 months' duration, when compared with feeding of longer than 6 months, was associated with increased odds ratios (OR) for acute lymphoblastic leukemia (OR = 3.43, 95% confidence interval [CI] 2.37-4.98; p < 0.001), Hodgkin's lymphoma (OR = 1.58, 95% CI: 0.88-2.84, p = 0.120), Non-Hodgkin's lymphoma (OR = 2.14, 95% CI: 1.25-3.65, p = 0.005), and overall (OR = 1.95, 95% CI: 1.40-2.71, p < 0.001). Cases also differed from controls with regard to FGIDs, such as stomach ache (p < 0.001), dyspepsia (p < 0.001), early satiety (p = 0.017), bowel satisfaction (p < 0.001), bloating (p < 0.001), nausea (p = 0.005), vomiting (p = 0.039), constipation (p = 0.003), diarrhea (p = 0.010), gastrointestinal canal congestion (p =0.039), muscle aches pains (p = 0.008), fecal incontinence (p = 0.021), and indigestion (p = 0.003). A multivariate stepwise regression analysis revealed that maternal smoking (p < 0.001), formula feeding (p < 0.001), duration of breastfeeding (p < 0.001), birth order (p = 0.002), mother's age (p = 0.004) and the child's birthweight (p = 0.009) were predictors for leukemia. Further analysis showed that dyspepsia (p < 0.001), gastrointestinal tract canal congestion (p < 0.001), constipation (p = 0.009), diarrhea (p = 0.013), bowel satisfaction (p = 0.021), bloating (p = 0.022), duration of breastfeeding (p < 0.001), and stomach ache (p = 0.025) were significant predictors for developing FGID symptoms after adjusting for age, gender, and other confounding variables. Conclusion: This study confirmed that breastfeeding has some effect on reducing possible risk of childhood lymphoma and leukemia and FGID symptoms compared with healthy control children.

Weight loss trends in Korean adolescents (2005-2021): Exploring the impact of measured and self-perceived weight status

ObjectiveThis study aims to assess the trends in the proportions of weight loss efforts among Korean adolescents aged 10–18 years from 2005 to 2021, examining variations based on weight status, to examine factors related to weight loss efforts by weight status, and to evaluate weight loss efforts based on the combination of measured and self-perceived weight status. MethodsComplex sample design analyses were conducted on a dataset comprising 10,760 adolescents, utilizing information from the Korea National Health and Nutrition Examination Survey, a nationally representative dataset. Participants were categorized into non-overweight and overweight groups using a BMI percentile threshold of 85. Results22–29 % of non-overweight adolescents and 54–77 % of adolescents with overweight engaged in weight loss efforts. Among adolescents who attempted to lose weight from 2005 to 2017, 39.5–57.1 % tried both of diet and exercise, 22.7–47.4 % tried exercise alone, and 10.2–26.7 % tried diet alone. Female gender, older age, and higher self-perceived weight status were associated with increased odds of weight loss efforts, irrespective of actual weight status. For adolescents perceiving themselves as obese, the odds of attempting weight loss were 8.32 for non-overweight boys, 2.02 for non-overweight girls, 15.28 for overweight boys, and 5.77 for overweight girls compared to controls who were non-overweight and perceived themselves as not obese. ConclusionWeight loss efforts among Korean adolescents aged 10 to 18 remained consistent irrespective of their actual weight over 16 years. Throughout this period, adolescents who perceived themselves as obese were more likely to attempt weight loss, independent of their true weight status. Hence, subjective weight perception plays a significant role in influencing weight loss behaviors among adolescents.

Is the rise in childhood obesity rates leading to an increase in hospitalizations due to dengue?

Background Obesity and diabetes are known risk factors for severe dengue. Therefore, we sought to investigate the association of obesity with increased risk of hospitalization, as there is limited information. Methods and findings Children aged 10 to 18 years (n = 4782), were recruited from 9 districts in Sri Lanka using a stratified multi-stage cluster sampling method. Details of previous admissions to hospital due to dengue and anthropometric measurements were recorded and seropositivity rates for dengue were assessed. The body mass index (BMI) centile in children aged 10 to 18, was derived by plotting the values on the WHO BMI-for-age growth charts, to acquire the percentile ranking. Results Although the dengue seropositivity rates were similar in children of the different BMI centiles, 12/66 (18.2%) seropositive children with a BMI centile &gt;97th, had been hospitalized for dengue, compared to 103/1086 (9.48%) of children with a BMI centile of &lt;97th. The logistic regression model suggested that BMI centiles 50th to 85th (OR = 1.06, 95% CI, 1.00 to 1.11, p = 0.048) and BMI centile of &gt;97th (OR 2.33, 95% CI, 1.47 to 3.67, p = 0.0003) was significantly associated with hospitalization when compared to children in other BMI categories. Conclusions Obesity appears to be associated with an increased risk of hospitalization in dengue, which should be further investigated in longitudinal prospective studies. With the increase in obesity in many countries, it would be important to create awareness regarding obesity and risk of severe disease and hospitalization in dengue.

Prevalence of Childhood Obesity in Indian Expatriate Children in Dubai: A Cross-Sectional Analytical Study.

Background Childhood obesity is one of the most prevalent nutritional disorders affecting children across the world, which further leads to diabetes, hypertension, coronary artery disease, and fatty liver disease in adulthood. The magnitude of this problem among Indian expatriates in the United Arab Emirates (UAE) has not been investigated before.This study delves into the prevalence of childhood obesity among this demographic and also provides a comparative analysis of the prevalence of obesity in UAE citizens and children in India. Methodology This is a cross-sectional study that investigates the prevalence of obesity in 3,698 students of a single Indian school in the UAE. Anonymous anthropometric data of these children of age range four to 18 years were analyzed. The International Obesity Task Force (IOTF), World Health Organization (WHO), and Centers for Disease Control (CDC) reference methods were used to calculate the prevalence of overweight, obesity, and extreme obesity. Results According to CDC guidelines, the prevalence of body mass index (BMI) ≥ 85th percentile, ≥ 95th percentile, and ≥ 99th percentile stands at 32.74%, 13.68%, and 5.1%, respectively. Children particularly boys aged more than 10 years are at a higher risk of being overweight, obese, and extremely obese (p = < 0.05). In children aged 10 years or less, as the age increases, they tend to have a higher BMI percentile and this is particularly prominent in boys (Pearson correlation coefficient 0.227). Conversely, in those over the age of 10 years, the BMI percentile decreases with age, particularly noticeable in girls, albeit without statistical significance. Conclusion Approximately one-third of school-aged Indian expatriates in the UAE are overweight, obese, or extremely obese. Our study, when contrasted with earlier studies, reveals that Emirati teenagers exhibit a higher prevalence of overweight and obesity compared to their Indian counterparts in the UAE.Similarly, the prevalence of childhood obesity among Indian expatriates in the UAE surpasses that among children residing in India.

Ethnic/racial and sex disparities in obstructive sleep apnea among adolescents in southern California.

Pediatric obstructive sleep apnea (OSA) is common; however, inclusion of adolescents and especially those of ethnic/racial minorities in research is scarce. We hypothesized that ethnic/racial minority adolescents undergoing polysomnography have higher prevalence and more severe OSA compared to those who are non-Hispanic (NH) White. Retrospective review of 1,745 adolescents undergoing diagnostic polysomnography. Demographic characteristics, age, body mass index percentile, and polysomnography parameters were obtained. Descriptive statistics comparing race/ethnicity were analyzed. Linear regression of log-transformed obstructive apnea-hypopnea index, and logistic regression of moderate-severe OSA (obstructive apnea-hypopnea index ≥ 5 events/h) adjusting for covariates were analyzed. A total of 58.2% adolescents were Hispanic, 24.1% NH-White, 4.3% NH-Asian/Pacific Islander, 4.2% NH-Black/African American, and 6.6% NH-other. Compared to the NH-White group, the Hispanic group had higher obstructive apnea-hypopnea index and any level of OSA severity, the Black/African American group had higher any level of OSA, and the NH-Asian group had higher moderate-severe OSA. Multiple linear regression of log-obstructive apnea-hypopnea index identified a positive association with Hispanic ethnicity (β: 0.25, P value < .05). Compared to the NH-White group, the Hispanic and the Asian/Pacific Islander groups were 1.45 (95% confidence interval: 1.10, 1.93) and 1.81 (95% confidence interval: 1.05, 3.10) times more likely to have moderate-severe OSA, respectively, after adjusting for relevant covariates. Stratified analysis by sex identified an association only among males between Hispanic ethnicity (odds ratio: 1.85, 95% confidence interval: 1.27, 2.70) and Asian/Pacific Islander ethnicity (odds ratio: 2.62, 95% confidence interval: 1.35, 5.11) and moderate-severe OSA, compared to the NH-White group. Among adolescents undergoing polysomnography evaluation, we identified OSA racial/ethnic and sex disparities in Hispanic and NH-Asian adolescents. Community level studies with adequate representation of these minority groups are needed to identify factors associated with the reported increased susceptibility.

Management for children and adolescents with overweight and obesity: a recommendations mapping.

Childhood obesity is a global public health issue, and the status of clinical practice guidelines (CPGs) as instruction manuals for the management of childhood obesity remains unclear. This study aims to identify and apprise the methodological and reporting quality of CPGs focused on childhood obesity and provide an overview of key recommendations. Databases and websites reporting guidelines were searched from January, 2018 to September, 2023. The methodological quality was graded using the AGREE II, and RIGHT was used to assess the reporting completeness. Among the six included CPGs, two were rated as high quality and considered "Recommended" and three were reported no less than 80%. CPGs included 184 recommendations cover diagnosis, assessment and management of complications, interventions and prevention. The diagnostic criteria for children with obesity over 2 years of age are based on normative BMI percentiles, depending on sex and age. CPGs recommended the delivery of multi-component behavior-changed interventions included controlling diet and increasing physical activity. Pharmacological interventions and bariatric surgery are considered as complementary therapies. CPGs for childhood obesity should emphasize the impact of psychological factors and consider the provision of interventions from multiple settings, and could consider the role of complementary alternative therapies. Six guidelines have been published in the past 5 years focusing children obesity. Recommendations covered diagnosis, multiple intervention and prevention. Guidelines should focus on the role of complementary alternative therapies. Guidelines should emphasize the impact of psychological factors. Guidelines should consider the provision of interventions from multiple settings.

Nutritional Trends in Cystic Fibrosis: Insights from the Italian Cystic Fibrosis Patient Registry.

Background: Over the past decades, efforts have been made to improve the nutritional well-being of people with cystic fibrosis (pwCF). Due to the correlation observed between nutritional indices and lung function, prevailing recommendations consistently advocate for BMI percentile goals at or above the 50th percentile in pwCF. Recent global trends show a notable increase in overweight and obese statuses among pwCF. This study aims to explore the nutritional status of Italian pwCF. Methods: Data from the Italian CF Patient's Registry were analysed to assess the proportion of individuals categorized as underweight, target weight, overweight, and obese from 2010 to 2021. Patient-level comparison data from 2021 were also examined to identify the potential determinants of overweight and obesity. Results: Analysis spanning 2010 to 2021 reveals a decrease of approximately 40% in underweight status among adults, while the proportion of malnourished patients younger than 18 years remained stable. Conversely, there was a substantial increase of over 70% in overweight status and over 85% in obesity among adults, with minor fluctuations observed among children and adolescents. Patient factors associated with increased obesity incidence included age older than 45 years, male gender, pancreatic sufficiency, possession of at least one CFTR variant conferring residual function, ppFEV1 > 90, and lower prevalence of Pseudomonas aeruginosa colonization. Conclusions: Our study confirms the evolving nutritional status landscape among Italian adult pwCF, with a significant shift towards overweight and obesity over the past decade. These trends highlight the need for proactive measures within CF standards of care to adapt and address the changing needs of patients.

Skin Reactions in Children with Type 1 Diabetes Associated with the Use of New Diabetes Technologies—An Observational Study from a Regional Polish Pediatric Diabetes Center

The study aimed to estimate the prevalence of skin problems in children and adolescents with type 1 diabetes (T1D) using insulin pumps (IPs) and/or continuous glucose monitoring (CGM) in our center and analyze their association with various factors. As part of the international ISPAD JENIOUS-initiated SKIN-PEDIC project, we interviewed and examined patients who visited the regional pediatric diabetes center in Opole (Poland) for four weeks regarding the use of IP and/or CGM and the presence of skin problems. Body mass index (BMI) and glycemic parameters were obtained retrospectively from medical records. Among 115 individuals (45.2% girls, 83.5% IP users, 96.5% CGM users), old scars were the most common skin problem (IP users 53.1%; CGM users 66.4%), while ≥2 types of skin problems co-occurred (IP users 40.6%; CGM users 27.3%). Longer IP use was associated with a higher prevalence of skin problems (50% for IP &lt; 1 year, 98.1%-IP 1–3 years, 100% for IP &gt; 3 years; p &lt; 0.001), pointing out extra attention with IP use &gt; 1 year. No significant associations were found between skin problems and gender, age, BMI centile and glycemic parameters. Dermatological complications were common among children using IP and CGM in our center, highlighting the need for vigilant monitoring and early intervention to manage these skin-related issues effectively.

Financial Incentives and Treatment Outcomes in Adolescents With Severe Obesity

Adolescent severe obesity is usually not effectively treated with traditional lifestyle modification therapy. Meal replacement therapy (MRT) shows short-term efficacy for body mass index (BMI; calculated as weight in kilograms divided by height in meters squared) reduction in adolescents, and financial incentives (FIs) may be an appropriate adjunct intervention to enhance long-term efficacy. To evaluate the effect of MRT plus FIs vs MRT alone on BMI, body fat, and cardiometabolic risk factors in adolescents with severe obesity. This was a randomized clinical trial of MRT plus FIs vs MRT alone at a large academic health center in the Midwest conducted from 2018 to 2022. Participants were adolescents (ages 13-17 y) with severe obesity (≥120% of the 95th BMI percentile based on sex and age or ≥35 BMI, whichever was lower) who were unaware of the FI component of the trial until they were randomized to MRT plus FIs or until the end of the trial. Study staff members collecting clinical measures were blinded to treatment condition. Data were analyzed from March 2022 to February 2024. MRT included provision of preportioned, calorie-controlled meals (~1200 kcals/d). In the MRT plus FI group, incentives were provided based on reduction in body weight from baseline. The primary end point was mean BMI percentage change from randomization to 52 weeks. Secondary end points included total body fat and cardiometabolic risk factors: blood pressure, triglyceride to high-density lipoprotein ratio, heart rate variability, and arterial stiffness. Cost-effectiveness was additionally evaluated. Safety was assessed through monthly adverse event monitoring and frequent assessment of unhealthy weight-control behaviors. Among 126 adolescents with severe obesity (73 female [57.9%]; mean [SD] age, 15.3 [1.2] years), 63 participants received MRT plus FIs and 63 participants received only MRT. At 52 weeks, the mean BMI reduction was greater by -5.9 percentage points (95% CI, -9.9 to -1.9 percentage points; P = .004) in the MRT plus FI compared with the MRT group. The MRT plus FI group had a greater reduction in mean total body fat mass by -4.8 kg (95% CI, -9.1 to -0.6 kg; P = .03) and was cost-effective (incremental cost-effectiveness ratio, $39 178 per quality-adjusted life year) compared with MRT alone. There were no significant differences in cardiometabolic risk factors or unhealthy weight-control behaviors between groups. In this study, adding FIs to MRT resulted in greater reductions in BMI and total body fat in adolescents with severe obesity without increased unhealthy weight-control behaviors. FIs were cost-effective and possibly promoted adherence to health behaviors. ClinicalTrials.gov Identifier: NCT03137433.

New-onset diabetes in children during the COVID-19 Pandemic: an assessment of biomarkers and psychosocial risk factors at play in Mississippi.

The coronavirus disease 2019 (COVID-19) pandemic has led to an association between COVID-19 and pediatric diabetes. Studies have indicated the increased likelihood of children with COVID-19 infection developing diabetes. Our objective was to assess not only the increase in pediatric diabetes at our hospital and identify possible risk factors, but also to correlate the psychosocial changes resulting from the pandemic with new-onset diabetes. We analyzed data from 58 children aged 1 to 18 years admitted to our hospital with new-onset diabetes between March 2020 and December 2021. The data included inflammatory biomarkers and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies (Abs), as well as the results of a lifestyle questionnaire. The average number of hospital admissions per month for new-onset diabetes increased from 10 to 18 with the start of the pandemic. Of the 58 children in our analysis, 33% had positive SARS-CoV-2 IgG Ab, 31% had type 1 diabetes mellitus, and 62% had type 2 diabetes mellitus (T2DM). More than half (54%) were experiencing diabetic ketoacidosis. Those with T2DM were older, majority African American, had higher median body mass index (BMI) percentiles, and lower vitamin D levels. There were no significant correlations between any psychosocial risk factors and either diabetes type or SARS-CoV2 Ab status. Despite the increased incidence of new-onset diabetes among children in Mississippi during the pandemic, this study was unable to demonstrate a significant correlation between COVID-19 infection and new-onset diabetes. The findings of this study highlighted the correlation between increased BMI and type 2 diabetes, underscoring the significant problems of obesity and diabetes in our study region. Further research is warranted.

FEEDING BEHAVIORS IN CHILDREN WITH AUTISM SPECTRUM DISORDER: A CROSS-SECTIONAL STUDY

This study aimed to examine the behavioral feeding problems in a sample of children with Autism Spectrum Disorder (ASD) and to examine the relationship of feeding problems to child sex and parents feelings about strategies to cope. This was a cross-sectional study of children aged 6-15 years with ASD. The parents or caregivers of the children/adolescents with ASD completed the following: sociodemographic information, questions about nutrition, and the Behavioral Pediatric Feeding Assessment Scale (BPFAS) for assessing the child’s behavioral feeding problems and parents’ feelings. Height and weight were used to calculate body mass index (BMI) percentiles. These percentiles for age and sex were used to define overweight and obesity (≥85th and ≥95th percentiles, respectively). The sample of the study consisted of 70 children with ASD (male: 49, female: 21), of which 45.8% were obese. The frequency of obesity in the males with ASD was higher than that in the females with ASD. BPFAS scores were higher in the females than in the males for all frequencies (total score, total problem score, child total score, child problem, parent total score, and parent problem). BPFAS total score was higher in the underweight children group (especially in the females). This study demonstrated that problematic feeding behaviors in children with ASD may differ according to sex. Behavioral interventions should be developed according to differences in feeding behavior.
