Abstract
OBJECTIVES Obesity and type 2 diabetes mellitus (T2DM) are growing health concerns. Since 2005, Student Health Service (SHS) and Hong Kong Paediatric Society formulated a protocol on urine glucose screening (UGS) for early diagnosis of T2DM in students with obesity in Hong Kong. This study reviews students with T2DM captured by this screening program and compare the data with the Hong Kong Children Diabetes Registry (HKCDR) database, to see if the UGS program facilitates early diagnosis of T2DM. METHODS Students between the ages of 10-18 years old with age- and sex-specific body mass index (BMI) >97th percentile who attended SHS between the school years from 2005/06 to 2017/18 were recruited for UGS. Those tested positive for random urine glucose underwent diagnostic testing for T2DM according to ADA guidelines. Demographic data and investigatory results from UGS and HKCDR within the same time period were compared. RESULTS A total of 216,526 students completed UGS in the said period; 415 (0.19 %) students were tested positive for urine glucose of which 121 students were diagnosed with T2DM. UGS picked up 23 % of the newly diagnosed T2DM cases. When compared to the HKCDR database, students diagnosed via UGS were significantly younger, less obese, and had fewer diabetic related complications. The negative predictive value of UGS is high and can effectively rule out T2DM. CONCLUSIONS Urine glucose screening is an inexpensive and simple test that allows for early diagnosis of T2DM among obese school students. Other methods including POCT HbA1c can be explored to improve program effectiveness.

Abstract
IMPORTANCE The prevalence of pediatric type 2 diabetes (T2D) is increasing globally. Girls with T2D are at risk of developing polycystic ovary syndrome (PCOS), but the prevalence of PCOS among girls with T2D is unknown. OBJECTIVE To determine the prevalence of PCOS in girls with T2D and to assess the association of obesity and race with this prevalence. DATA SOURCES In this systematic review and meta-analysis, MEDLINE, Embase, CINAHL, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Web of Science: Conference Proceedings Citation Index-Science, and the gray literature were searched from inception to April 4, 2021. STUDY SELECTION Two reviewers independently screened for studies with observational study design that recruited 10 or more participants and reported the prevalence of PCOS in girls with T2D. DATA EXTRACTION AND SYNTHESIS Risk of bias was evaluated using a validated tool, and level of evidence was assessed using the Oxford Centre for Evidence-Based Medicine criteria. A random-effects meta-analysis was performed. This study follows the Meta-analysis of Observational Studies in Epidemiology (MOOSE) reporting guideline. MAIN OUTCOMES AND MEASURES The main outcome of this systematic review was the prevalence of PCOS in girls with T2D. Secondary outcomes included assessing the associations of obesity and race with PCOS prevalence. RESULTS Of 722 screened studies, 6 studies involving 470 girls with T2D (mean age at diagnosis, 12.9-16.1 years) met the inclusion criteria. The prevalence (weighted percentage) of PCOS was 19.58% (95% CI, 12.02%-27.14%; I2 = 74%; P = .002). Heterogeneity was moderate to high; however, it was significantly reduced after excluding studies that did not report PCOS diagnostic criteria, leading to a calculated prevalence (weighted percentage) of 24.04% (95% CI, 15.07%-33.01%; I2 = 0%; P = .92). Associations with obesity and race could not be determined because of data paucity. CONCLUSIONS AND RELEVANCE In this meta-analysis, approximately 1 in 5 girls with T2D had PCOS, but the results of this meta-analysis should be considered with caution because studies including the larger numbers of girls did not report the criteria used to diagnose PCOS, which is a challenge during adolescence. The associations of obesity and race with PCOS prevalence among girls with T2D need further evaluation to help define at-risk subgroups and implement early assessment and treatment strategies to improve management of this T2D-related comorbidity.

Abstract
PURPOSE OF REVIEW The present review focuses on the epidemiology of type 2 diabetes (T2D) in Indigenous communities in the continental United States (U.S.)-including disease prevention and management-and discusses special considerations in conducting research with Indigenous communities. RECENT FINDINGS Previous studies have reported the disparately high prevalence of diabetes, especially T2D, among Indigenous peoples in the U.S. The high prevalence and incidence of early-onset T2D in Indigenous youth relative to that of all youth in the U.S. population pose challenges to the prevention of complications of diabetes. Behavioral, dietary, lifestyle, and genetic factors associated with T2D in Indigenous communities are often investigated. More limited is the discussion of the historical and ongoing consequences of colonization and displacement that impact the aforementioned risk factors. Future research is necessary to assess community-specific needs with respect to diabetes prevention and management across the diversity of Indigenous communities in the U.S.

Abstract
Diabetes is a common disease among pediatric populations in the United States and worldwide. The incidence of type 1 and type 2 diabetes is increasing, with disproportional increases in racial/ethnic subpopulations. As the prevalence of obesity continue to increase, type 2 diabetes now represents a major form of pediatric diabetes. The management of diabetes in youth centers on maintaining glycemic control to prevent acute and chronic complications. This article summarizes the epidemiology, etiology, management, and complications of type 1 and type 2 diabetes in youth, as well as future directions and opportunities.

Abstract
AIMS/HYPOTHESIS Youth with type 2 diabetes (T2D) have high rates of obesity, hypertension and suboptimal glycemic control. We hypothesized that renin-angiotensin system (RAS) activation is present in youth with T2D and associated with poor glycemic control and renal outcomes. METHODS Cross-sectional analysis of 183 youth with T2D and 100 controls from the Improving renal Complications in Adolescents with T2D through REsearch cohort. Diabetes youth stratified by urine albumin:creatinine ratio (ACR) < or ≥2 mg/mmol. RAS levels measured with enzyme-linked immunosorbent assay (ELISA) and enzyme activities by synthetic substrates. In T2D, levels log transformed and Tobit linear regressions evaluated for associations with hemoglobin A1c (HbA1c), mean arterial pressure (MAP), estimated glomerular filtration rate (eGFR), ACR. RESULTS Youth were 14 to 15 years, with diabetes duration 1.7 to 1.8 years; 21.3% albuminuria. Serum: differences in plasma renin activity (<0.0001), and angiotensin converting enzyme (ACE) activity (P = .003) in T2D vs controls. Urine: higher ACE activity and ACE2 protein/activity (all P < .0001) in T2D, higher levels in T2D with albuminuria. Multivariable regressions: higher serum ACE activity (ß = 0.03, SE 0.01;P < .01), urine ACE activity (ß = 0.44, SE 0.18;P < .01), ACE2 (ß = 0.51, SE 0.19;P < .01) positively associated with HbA1c; urine angiotensinogen (AGT) negatively associated (ß = -0.28 [SE 0.06;P < .01]). Higher serum aldosterone (ß = 0.11 [SE 0.04;P < .01]) and urine AGT (ß = 0.32 [SE 0.07;P < .01]) significantly associated with ACR and urine ACE2 (ß = 0.21 [SE 0.13;P < .03]). No associations between RAS markers and eGFR/MAP. CONCLUSIONS/INTERPRETATION RAS activation present in youth with T2D and associated with higher HbA1c. Higher serum aldosterone and urine AGT associated with albuminuria. The prognostic significance of the combined effect of glycemia and RAS activation on renal outcomes requires additional investigation.

Abstract
Diabetes Mellitus (DM) is a multi-factorial chronic health condition that affects a large part of population and according to the World Health Organization (WHO) the number of adults living with diabetes is expected to increase. Since type 2 diabetes mellitus (T2DM) is suffered by the majority of diabetic patients (around 90-95%) and often the mono-target therapy fails in managing blood glucose levels and the other comorbidities, this review focuses on the potential drugs acting on multi-targets involved in the treatment of this type of diabetes. In particular, the review considers the main systems directly involved in T2DM or involved in diabetes comorbidities. Agonists acting on incretin, glucagon systems, as well as on peroxisome proliferation activated receptors are considered. Inhibitors which target either aldose reductase and tyrosine phosphatase 1B or sodium glucose transporters 1 and 2 are taken into account. Moreover, with a view at the multi-target approaches for T2DM some phytocomplexes are also discussed.

Abstract
BACKGROUND/PURPOSE Type 2 diabetes has become an important cause of diabetes in children. Since most children with type 2 diabetes are asymptomatic, a screening method is needed. However, physicians are required in the screening methods recommended by professional associations. We aimed to develop a simple and efficient screening method for children with diabetes. METHODS A nationwide survey was conducted, which included 2,270,496 seventh-grade students. Students with two abnormal results in sequential urinalyses were given a fasting blood test. Three screening methods were developed. RESULTS Among the screening methods, method C is simple, and can be performed by parents, teachers, or school nurses. It suggests children with two abnormal results in sequential urinalyses and who are overweight or have a family history of diabetes receive blood tests. As a result, 0.10% of boys and 0.16% of girls were recommended to receive blood tests, and 7.0% of boys and 6.7% of girls receiving blood tests were diagnosed diabetes. On average, 15,002 boys and 9056 girls had to be screened to find one child with diabetes. The cost per 1000 children by method C was 2466.84 US dollars. CONCLUSION Urinalysis screening followed by evaluation of risk factors is a simple and efficient way to identify children with diabetes in schools.

Abstract
The economic issues related to medical treatments in youth with type 2 diabetes (T2D) are rarely reported and thus not fully understood. The Treatment Options for type 2 Diabetes in Adolescents and Youth clinical trial of youth recently diagnosed with T2D collected healthcare and related cost information from the largest cohort studied to date. Costs related to medical treatments and expenses faced by caregivers were identified over a 2-year period from 496 participants. Data were collected by surveys and diaries to document frequency of use of diabetes care (excluding study laboratory tests), non-diabetes care services and treatments, caregiver time, and expenses related to exercise and dietary activities recommended for patients. Economic costs were derived by applying national cost values to the reported utilization frequency data. Annual medical costs in the first year varied by the treatment group, averaging $1798 in those assigned to metformin alone (M), $2971 to combination drug therapy with metformin + rosiglitazone (M + R), and $2092 to metformin + an intensive lifestyle and behavior change program (M + L). Differences were primarily due to costs related to combination drug therapy. Adult caregiver support costs were higher for participants in the lifestyle program, which was delivered in weekly sessions in the first 6 months. Expenses for purchases to enhance diet and exercise change did not vary by treatment assignment. In year 2, medication costs increased in M and M + L due to the initiation of insulin in subjects who failed to maintain glycemic control on the assigned treatment. Data are reported for use by researchers and those providing healthcare to this vulnerable patient population.

A life-course approach to early-onset of diabetes mellitus: Probable contribution of collective violence in Mexico. ADVANCES IN LIFE COURSE RESEARCH 2019; 40:30-42.

Abstract
Type 2 diabetes mellitus (T2DM) is a growing health problem among the pediatric population in the world, and particularly in Mexico. Official data in Mexico reported that during the period from 2003 to 2013 there was an increase in the cumulative incidence among older adolescents between 2010 and 2012, which decreased to the usual measures in 2013. All these variations occurred in a period in which collective violence permeated all levels of Mexican society. It can be argued that there might be a relationship between the two phenomena. This is an ecologic analytical study of trends over time comprising older adolescents (15-19 year olds). T2DM cumulative incidence and mortality rates attributable to violent death (VD) were standardized by direct method according to the World Health Organization. Data were sourced from nationwide official reports. Time series analysis was performed with ARIMA models and significant predictors. The disease ecology analysis was done using cluster analysis. Using significant predictors with ARIMA models, we found that the male VD mortality rates series could forecast 63.1% of the temporal variability of the cumulative incidence of T2DM series. Geographically, states with higher rates of violence also showed a higher incidence of T2DM. These data suggest that collective violence may make some contribution to the early onset of T2DM among adolescents, particularly in those regions most affected by violence. These findings can be conducive to opening new lines of research to explore the relationship between variables at the individual level and the clinical implications.

Brar PC. Update on the current modalities used to screen high risk youth for prediabetes and/or type 2 diabetes mellitus. Ann Pediatr Endocrinol Metab 2019; 24:71-77. [PMID: 31261470 PMCID: PMC6603607 DOI: 10.6065/apem.2019.24.2.71] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2019] [Revised: 06/03/2019] [Accepted: 06/11/2019] [Indexed: 01/08/2023] Open
Abstract
The modalities currently employed to screen for type 2 diabetes mellitus (T2DM)/prediabetes are HbA1c, fasting plasma glucose (FPG), and 2-hour plasma glucose (PG) during an oral glucose tolerance test (OGTT). The purpose of this review is to highlight the positive qualities and pitfalls of these diagnostic modalities and reflect on the most reasonable and effective approach to screen high risk youth. Given its inherent preanalytical advantages, glycated hemoglobin (HbA1c) continues to be the preferred diagnostic modality used by pediatricians to screen high risk youth. However, when the three aforementioned tests are performed in youths of different races/ethnicities, discrepant results for T2DM/prediabetes are observed. The prevalence rates for T2DM vary from 0.53% in Chinese youth (including youth of all body mass indexes) to 18.3% in high-risk, overweight, obese Korean youth. Moreover, the FPG is abnormal (>100 less than <126 mg/dL) in 15% of Korean youth versus 8.7% of Chinese youth. The prevalence rates for prediabetes are 1.49% in Chinese youth versus 21% in Emirati youth (HbA1c, 5.7%-6.4%). The coefficient of agreement, k, between these screening tests for T2DM are fair, 0.45-0.5 across all youth. However, using HbA1c as a comparator, the agreement is weak with FPG (k=0.18 in German youth versus k=0.396 in Korean youth). The American Diabetes Association (ADA) Standards of Medical Care Guidelines define "high risk youth" who need to be tested for T2DM and/or prediabetes. OGTT and HbA1c do not always detect T2DM in similar individuals. HbA1c may not be an ideal test for screening Hispanic and African American youth. FPG and OGTT are suitable screening tests for youth of ethnic minorities and those with cystic fibrosis or hemoglobinopathies. Performing all three tests either together or sequentially may be the only way to encompass all youth who have aberrations in different aspects of glucose homeostasis.

Abstract
The incidence of diabetes mellitus (DM) is on the rise, worldwide. One of the main complications in DM is delayed wound healing and it often requires amputation. Various drugs were used to treat DM but they presented with adverse effects. Often, patients failed to comply with such treatment. This opened the door for complementary and alternative medicine. In the present review, we explored the molecular concept of wound healing occurring in different stages with special emphasis to DM. We also highlighted the potential herbal products such as NF3 (Chinese 2-Herb Formula), Zicao, Jing Wan Hong ointment, Aleo vera, mixture of Adiantum capillus-veneris, Commiphora molmol, Aloe vera, and henna, Phenol-rich compound sweet gel, Jinchuang ointment, San-huang-sheng-fu (S) oil, Yi Bu A Jie extract, Astragali Radix (AR) and Rehmanniae Radix (RR), Yiqi Huayu, Tangzu yuyang ointment, Shengji Huayu recipe, Angelica sinensis, Lithospermun erythrorhison, Hippophae rhamnoides L., Curcuma longa and Momordica charantia that could be used effectively to treat DM wounds. Future clinical trials are needed for designing potential drugs which may be effective in treating DM wounds.

Abstract
BACKGROUND The prevalence of type 2 diabetes mellitus (T2DM) in children and adolescents is increasing. This has spurred the development and publication of clinical practice guidelines (CPGs) for the management of paediatric T2DM. Given the long-term complications of T2DM, optimal management is important to prevent or delay these complications. However, the quality of published CPGs has not yet been empirically evaluated. Our objective is to systematically appraise all published CPGs for the management of T2DM in children and adolescents. METHODS We will identify all published CPGs that address T2DM in children and adolescents through MEDLINE, Embase, CINAHL, Trip, and the National Guideline Clearinghouse and will screen diabetes and paediatric societies and associations' websites. Search records will be screened in duplicate for inclusion. Grey literature will be covered by systematically searching publications of all relevant diabetes societies and associations and other health organizations for CPGs that meet our inclusion criteria. CPGs deemed eligible for inclusion will be retrieved. Quality assessment will be conducted using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) tool by a team of four appraisers. Scaled scores of the AGREE II will be used to gauge the overall quality of CPGs. DISCUSSION The results of this review will be disseminated through presentations at local, national, and international conferences and publication in a peer-reviewed journal. The results of this review can help improve the reporting of future guidelines, inform decisions of policy-makers to endorse CPGs, and affect the choice of guideline use in clinical practice.

Abstract
Respected members of American Indian and Alaska Native communities are a critical resource in helping communities mobilize efforts in diabetes prevention and care. Possessing cultural and historical knowledge and training in health promotion and social support, community health representatives (CHRs) are uniquely equipped to broker the needed relationship between a world shaped by culture and history and the world of conventional scientific knowledge. Grounded in principles of social support and interpersonal communication, as well as an understanding of their community’s strengths and history in health protection, CHRs are bridges distinctively positioned to connect these two worlds. With additional training and mentoring in diabetes care and prevention, CHRs, in their self-described roles as “in-between people,” can serve both as caring and knowledgeable community members and valuable members of the health care team.

Are hepatic and soleus lipid content, assessed by magnetic resonance spectroscopy, associated with low birth weight or insulin resistance in a rural Indian population of healthy young men?

Abstract
AIMS To assess young healthy men from rural India, who had normal or low birth weights, using magnetic resonance spectroscopy to determine the potential differences in ectopic fat storage between birth weight groups, and to determine if ectopic fat storage was associated with insulin resistance in this population. METHODS A total of 54 lean men with normal birth weight and 49 lean men with low birth weight (age range 18-22 years) from rural India were recruited. All the men underwent anthropometry, magnetic resonance spectroscopy, a hyperinsulinaemic-euglycaemic clamp and a dual-energy X-ray absorptiometry. RESULTS The median (interquartile range) values for hepatic cellular lipids, intramyocellular lipids and extramyocellular lipids, measured using magnetic resonance spectroscopy were 0.76 (0.1-1.8)%, 1.27 (1.0-2.3)% and 1.89 (1.3-3.2)%, respectively, for the normal birth weight group and 0.4 (0.1-1.3)%, 1.38 (0.9-2.2)% and 2.07 (1.2-2.8)%, respectively, for the low birth weight group (P > 0.05). No difference in ectopic fat storage was observed between the low and normal birth weight groups, with or without adjustment for age and total fat percentage. Homeostatic model assessment of insulin resistance values were not associated with hepatic cellular, intramyocellular or extramyocellular lipid content in any of the groups. Total fat percentage was the only independent predictor of intramyocellular and extramyocellular lipid content. CONCLUSION Young and lean men from rural India with low birth weight were not observed to have ectopic fat storage in the liver or muscle, and the amount of liver and muscle fat was unrelated to insulin resistance. Older age and/or an urban affluent lifestyle may be required to show a potential role of ectopic fat storage on insulin resistance in Indian people with low or normal birth weight.

Abstract
AIM To investigate insulin sensitivity and insulin secretion patterns among Asian Indian youth without and with type 2 diabetes (T2DM-y defined as onset of diabetes at or below 25 years) with normal and high visceral fat (VF) levels. METHODS We recruited 74 T2DM-y individuals, within 18 months of diagnosis and compared them to 77 age-matched controls with normal glucose tolerance (NGT). Using L4/L5 abdominal CT images, VF levels were categorized as normal or high according to their median values. Oral glucose tolerance tests (glucose and insulin measures) were used to derive Matsuda index, insulin resistance (HOMA-IR) and oral disposition index (DIo). Relationships between measures of insulin sensitivity and secretion and T2DM-y by VF level were assessed using standardized multinomial regression models. RESULTS Participants were categorized into four groups: NGT-normal VF; NGT-high VF; T2DM-normal VF, and T2DM-high VF. Among NGTs, those with high VF had significantly lower insulin sensitivity (0.013 vs.0.019 pM(-1)) and Matsuda index (10.2 vs.13.8), than normal VF. When compared, T2DM-high VF had lowest insulin sensitivity (0.009 vs.0.019, 0.013, 0.012 pM-1; p<0.001), Matsuda index (6.4 vs. 13.8, 10.2, 8.6; p<0.001), OGIS120 (305 vs. 396, 382, 316; p<0.001) and DIo (0.48 vs. 3.75, 3.20, 0.55 mmol/L; p<0.001). At every category of 2 h PG values, NGT-high VF had lower DIo than NGT-normal VF participants. In standardized multinomial models, that included DIo and Matsuda index adjusted for age, gender, BMI, and leptin, DIo (Odds ratio: 0.001; 95%Confidence interval: 0.000-0.020), matsuda index (0.26; 0.07-0.93), age (2.92; 1.18-7.19) and leptin (3.17; 1.12-8.99) were associated with high VF among T2DM. CONCLUSION Lower DIo and Matsuda index, younger age and higher leptin were independently associated with high visceral fat among T2DM participants. Also, lower DIo was seen with increasing 2 h PG values even among normal glucose tolerant individuals.

Abstract
BACKGROUND Our previous work has shown that type 2 diabetes mellitus is a problem in the school-aged population of Trinidad, West Indies. The current study evaluated the prevalence in this population of selected risk factors for diabetes, viz: obesity, family history of diabetes and acanthosis nigricans. OBJECTIVE To assess the prevalence of the following risk factors for type 2 diabetes (T2DM) in school children in Trinidad: obesity, family history of diabetes in first- or second-degree relatives and the presence of acanthosis nigricans (AN). METHODS A cross-sectional survey was performed among school children aged 7-18 years from September 2009 to June 2010. A convenience sample was selected from a random sample of 32 schools drawn from all educational districts. A self-administered questionnaire was employed to record family history, gender and ethnicity. AN was assessed and scored clinically at the neck and obesity was measured by anthropometry and bio-impedance. RESULTS There were 2130 participants in the study. Fifteen per cent were obese and 17% were overweight. Primary school children had a higher prevalence of obesity (22·9% vs 11·0%) and overweight (20·0% vs 15·6%) than secondary school children (P<0·05). A greater proportion of males than females had combined overweight/obesity as measured by BMI for age (35·8 vs 29·4%, P<0·05). The overall prevalence of AN was 43·4%. However, just over 18% of all school children have a degree of AN greater than grade 2, which clinically is readily recognisable. Females displayed this physical sign more commonly than males (P<0·05). The prevalences of a family history of diabetes in first- and second-degrees relatives were 11·0% and 1·1%, respectively. Forty-three per cent had one risk factor for diabetes, 23·1% had two and 2·9% had three. CONCLUSION Risk factors for T2DM are very common among school children in Trinidad. More than 40% had at least one risk factor. Strategies aimed at reducing risk factors for T2DM, especially obesity, among Trinidadian school children are urgently warranted.

Abstract
Global rates of type 2 diabetes in children and adolescents have increased significantly over the past three decades. Type 2 diabetes is a relatively new disease in this age group, and there is a dearth of information about how to structure treatment programs to manage its comorbidities and complications. In this paper, we describe the design and implementation of a personalized multidisciplinary, family-centered, pediatric and adolescent type 2 diabetes program at a tertiary pediatric center in Hamilton, Ontario, Canada. We report the process of designing and implementing such a program, and show that this multidisciplinary program led to improvement in glycated hemoglobin (n=17, 8% at baseline versus 6.4% at 1 year, 95% confidence interval (0.1–0.28), P-value <0.0001) and stabilized body mass index, with lowered C-peptide and no change in fitness or metabolic biomarkers of lipid metabolism and liver function. As type 2 diabetes becomes more prevalent in youth, the need for programs that successfully address the complex nature of this disease is central to its management and to mitigate its long-term adverse outcomes.

This planning workshop was funded by the Canadian Institutes of Health Research (CIHR) to bring together researchers with expertise in the area of maternal obesity (OB) and weight gain in pregnancy and pregnancy-related disease to attend a one-day workshop and symposium to discuss the development of a cross-Canada lifestyle intervention trial for targeting pregnant women. This future intervention will aim to reduce downstream OB in children through encouraging appropriate weight gain during the mother’s pregnancy. The workshop served to (i) inform the development of a lifestyle intervention for women with a high pre-pregnancy body mass index (BMI), (ii) identify site investigators across Canada, and (iii) guide the development of a grant proposal focusing on the health of mom and baby. A brief summary of the presentations as well as the focus groups is presented for use in planning future research.

Prevalence of diabetes in U.S. youth in 2009: the SEARCH for diabetes in youth study. Diabetes Care 2014; 37:402-8. [PMID: 24041677 PMCID: PMC3898760 DOI: 10.2337/dc13-1838] [Citation(s) in RCA: 312] [Impact Index Per Article: 31.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/03/2013] [Accepted: 09/09/2013] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To estimate the prevalence of diabetes in U.S. youth aged <20 years in 2009 and to estimate the total number of youth with diabetes in the U.S. by age, race/ethnicity, and diabetes type. RESEARCH DESIGN AND METHODS To address one of its primary aims, the SEARCH for Diabetes in Youth Study identified youth aged <20 years on 31 December 2009 with physician-diagnosed diabetes in selected areas of Colorado, Ohio, South Carolina, and Washington, among health plan members of Kaiser Permanente Southern California and among American Indians living on reservations in Arizona and New Mexico. Diabetes was classified as type 1, type 2, or other. Race/ethnicity was by self-report. RESULTS From a population of 3,458,974 youth aged <20 years, 7,695 youth with diabetes were identified (2.22/1,000): 6,668 with type 1 diabetes (1.93/1,000), 837 with type 2 diabetes (0.24/1,000), and 190 (0.05/1,000) with other diabetes types. Prevalence increased with age, was slightly higher in females than males, and was most prevalent in non-Hispanic White and least prevalent in Asian/Pacific Islanders, with Native American and black youth having the highest prevalence of type 2 diabetes. An estimated 191,986 U.S. youth aged <20 years have diabetes; 166,984 type 1 diabetes, 20,262 type 2 diabetes, and 4,740 other types. CONCLUSIONS Diabetes, one of the leading chronic diseases in childhood, affects >190,000 (1 of 433) youth aged <20 years in the U.S., with racial and ethnic disparities seen in diabetes prevalence, overall and by diabetes type.

Effects of parental origins and length of residency on adiposity measures andnutrition in urban middle school students: a cross-sectional study. INTERNATIONAL JOURNAL OF PEDIATRIC ENDOCRINOLOGY 2013; 2013:16. [PMID: 24134822 PMCID: PMC3875353 DOI: 10.1186/1687-9856-2013-16] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/15/2013] [Accepted: 10/14/2013] [Indexed: 11/25/2022]
Abstract
Background The prevalence of obesity in U.S. has been rising at an alarming rate,
particularly among Hispanic, African, and Asian minority groups. This trend
is due in part to excessive calorie consumption and sedentary lifestyle. We
sought to investigate whether parental origins influence eating behaviors in
healthy urban middle school students. Methods A multiethnic/racial population of students (N = 182) enrolled in
the ROAD (Reduce Obesity and Diabetes) Study, a school-based trial to assess
clinical, behavioral, and biochemical risk factors for adiposity and its
co-morbidities completed questionnaires regarding parental origins, length
of US residency, and food behaviors and preferences. The primary behavioral
questionnaire outcome variables were nutrition knowledge, attitude,
intention and behavior, which were then related to anthropometric measures
of waist circumference, BMI z-scores, and percent body fat. Two-way analysis
of variance was used to evaluate the joint effects of number of parents born
in the U.S. and ethnicity on food preference and knowledge score. The
Tukey-Kramer method was used to compute pairwise comparisons to determine
where differences lie. Analysis of covariance (ANCOVA) was used to analyze
the joint effects of number of parents born in the US and student ethnicity,
along with the interaction term, on each adiposity measure outcome. Pearson
correlation coefficients were used to examine the relationships between
maternal and paternal length of residency in the US with measures of
adiposity, food preference and food knowledge. Results African Americans had significantly higher BMI, waist circumference and body
fat percentage compared to other racial and ethnic groups. Neither
ethnicity/race nor parental origins had an impact on nutrition behavior.
Mothers’ length of US residency positively correlated with
students’ nutrition knowledge, but not food attitude, intention or
behavior. Conclusions Adiposity measures in children differ according to ethnicity and race. In
contrast, food behaviors in this middle school sample were not influenced by
parental origins. Longer maternal US residency benefited offspring in terms
of nutrition knowledge only. We suggest that interventions to prevent
obesity begin in early childhood.

Abstract
Type 2 diabetes (T2D) was an adult disease until recently, but the rising rates of obesity around the world have resulted in a younger age at presentation. Children who have T2D have several comorbidities and complications reminiscent of adult diabetes, but these are appearing in teens instead of midlife. In this review, we discuss the clinical presentation and management options for youth with T2D. We discuss the elements of lifestyle intervention programs and allude to pharmacotherapeutic options used in the treatment of T2D youth. We also discuss comorbidities and complications seen in T2D in children and adolescents.

Abstract
Introduction The diabetes mellitus Incidence Cohort Registry (DiMelli) aims to characterize diabetes phenotypes by immunologic, metabolic, and genetic markers. We classified patients into three groups according to islet autoantibody status and examined whether patients with multiple diabetes-associated autoantibodies, one autoantibody, or without autoantibodies differed with respect to clinical, metabolic, and genetic parameters, including an insulin sensitivity (IS) score based on waist, HbA1c, and triglycerides. We also assessed whether metabolic markers predicted the immune status. Materials and Methods As of June 2012, 630 patients in Bavaria, Germany, aged <20 years diagnosed with any type of diabetes within the preceding 6 months were registered in DiMelli. We compared the clinical and laboratory parameters between islet autoantibody status defined patient groups. Parameters showing the strongest associations were included in principal component analysis. Receiver operating characteristic curves were used to assess the ability of the IS Score to predict islet autoantibody status. Results Patients with multiple islet autoantibodies, one autoantibody, or without autoantibodies were significantly different in terms of BMI percentile, weight loss before diagnosis, fasting C-peptide (all, P<0.001), and IS Score (P=0.034). However, principal component analysis revealed no distinct patterns according to autoantibody status. At the optimal IS Score cut-off for predicting islet autoantibody positivity (single compared to none), the specificity was 52.0% and the sensitivity was 86.8%. With respect to prediction of multiple autoantibodies (compared to none), specificity and sensitivity were slightly lower and in combination inferior to those obtained using the BMI percentile and fasting C-peptide. Discussion The DiMelli study indicated that patients with and without islet autoantibodies differed with respect to metabolic and genetic markers but there was considerable overlap of phenotypes, and autoantibody status could not be predicted by these parameters. Thus, our results suggest that refined diabetes classification may require both immune and metabolic phenotyping.

Abstract
Over the past 3 decades, the prevalence of childhood obesity has increased dramatically in North America, ushering in a variety of health problems, including type 2 diabetes mellitus (T2DM), which previously was not typically seen until much later in life. The rapid emergence of childhood T2DM poses challenges to many physicians who find themselves generally ill-equipped to treat adult diseases encountered in children. This clinical practice guideline was developed to provide evidence-based recommendations on managing 10- to 18-year-old patients in whom T2DM has been diagnosed. The American Academy of Pediatrics (AAP) convened a Subcommittee on Management of T2DM in Children and Adolescents with the support of the American Diabetes Association, the Pediatric Endocrine Society, the American Academy of Family Physicians, and the Academy of Nutrition and Dietetics (formerly the American Dietetic Association). These groups collaborated to develop an evidence report that served as a major source of information for these practice guideline recommendations. The guideline emphasizes the use of management modalities that have been shown to affect clinical outcomes in this pediatric population. Recommendations are made for situations in which either insulin or metformin is the preferred first-line treatment of children and adolescents with T2DM. The recommendations suggest integrating lifestyle modifications (ie, diet and exercise) in concert with medication rather than as an isolated initial treatment approach. Guidelines for frequency of monitoring hemoglobin A1c (HbA1c) and finger-stick blood glucose (BG) concentrations are presented. Decisions were made on the basis of a systematic grading of the quality of evidence and strength of recommendation. The clinical practice guideline underwent peer review before it was approved by the AAP. This clinical practice guideline is not intended to replace clinical judgment or establish a protocol for the care of all children with T2DM, and its recommendations may not provide the only appropriate approach to the management of children with T2DM. Providers should consult experts trained in the care of children and adolescents with T2DM when treatment goals are not met or when therapy with insulin is initiated. The AAP acknowledges that some primary care clinicians may not be confident of their ability to successfully treat T2DM in a child because of the child's age, coexisting conditions, and/or other concerns. At any point at which a clinician feels he or she is not adequately trained or is uncertain about treatment, a referral to a pediatric medical subspecialist should be made. If a diagnosis of T2DM is made by a pediatric medical subspecialist, the primary care clinician should develop a comanagement strategy with the subspecialist to ensure that the child continues to receive appropriate care consistent with a medical home model in which the pediatrician partners with parents to ensure that all health needs are met.

Abstract
BACKGROUND To improve support and justification for health promotion efforts in schools, it is helpful to understand how students' health behaviors affect academic performance. METHODS Fifth-grade students completed an online school-administered health survey with questions regarding their eating behavior, physical activity, academic performance, and sleep patterns. Differences in health behaviors were examined by sex, self-reported weight status, and sufficient (≥9 hours) versus insufficient sleep. Logistic regression was used to determine the relationship between academic performance and the health behaviors. RESULTS One third of the sample did not get the recommended amount of physical activity and more than half of the students watched television ≥ 2 hours/day. Self-reported overweight status was related to lower self-reported academic performance, fewer lunch and breakfast occasions, less physical activity, not meeting the recommendations for vegetable and soda consumption as well as hours of television watching. Sufficient sleep (≥9 hours/night) was associated with better grades, meeting the recommended hours of daily television watching and video game playing, being more physically active and increased breakfast and lunch frequency. Percentage of serving free/reduced lunch, soda consumption, breakfast frequency, amount of physical activity, and television watching were associated with academic performance. CONCLUSION More positive health behaviors generally were associated with better academic performance. Promoting healthy behaviors in schools might improve not only students' health academic performance as well.

Abstract
Obesity and obesity-related diseases (cardiovascular disease/metabolic risk factors) are experienced differently in individuals from different ethnic backgrounds, which originate in childhood. Physical activity is a modifiable risk factor for obesity and related diseases. Both physical activity and metabolic risk factors track to adulthood, and thus understanding the physical activity patterns in children from different ethnic backgrounds is important. Given the limitations of self-report measures in children, this study provides a review of studies which have objectively measured physical activity patterns in children from different ethnic backgrounds. From a total of 16 studies, it can be concluded that physical activity does seem to vary amongst the ethnic groups especially South Asian and Black compared to White EU (European Union). The findings are less consistent for Hispanic/Mexican American children. However, there are several methodological limitations which need to be considered in future studies. Firstly, there is a need for consistency in the measurement of physical activity. Secondly, there are a range of complex factors such as socioeconomic status and body composition which affect both physical activity and ethnicity. Studies have failed to account for these differences limiting the ability to generalise that ethnicity is an independent risk factor for physical activity.

Abstract
Abstract Body mass and anti-pancreatic antibody status potentially influences the presentation of diabetes in children. We hypothesized that anti-pancreatic auto-antibody positive patients with new onset diabetes would have lower levels of insulin and C-peptide at presentation, and hence higher HbA1c. Records of children with new onset diabetes self-identified as African American were retrospectively analyzed. Patients were under 19 years of age. Anti-GAD65 antibody titer, HbA1c, blood glucose, insulin and C-peptide levels were drawn at the time of diagnosis. Patients were classified as antibody positive if anti-GAD65 was ≥ 0.5. HbA1c, insulin and C-peptide levels were considered as dependent variables in statistical models that included auto-antibody status, gender, age, body mass index z score (BMI-z score), and blood glucose as independent covariates. Records of 61 African-American children were available for analysis. There was no statistical association of auto-antibody status or initial clinical diagnosis with HbA1c, insulin or C-peptide level. BMI-z score was strongly associated with insulin (p=0.0006) and C-peptide (p<0.0001) levels. In general, higher BMI-z score, female gender and older age were associated with higher C-peptide levels. Although potentially helpful in eventually determining etiology, pancreatic auto-antibody levels do not have an association with HbA1c, insulin or C-peptide levels in African-American children with new onset diabetes. BMI-z score had the most robust association with insulin and C-peptide levels at presentation.

Abstract
OBJECTIVE This study aimed to compare the discriminating power of HbA(1C) with other pre-diabetes diagnostic tests specifically in high-risk African American children. RESEARCH DESIGN AND METHODS A cross-sectional analysis was performed on a sample of 172 children (70 boys and 102 girls) aged 9-11 years with BMI's above the 85th percentile. Fasting glucose, insulin and HbA(1C) were analyzed from the plasma samples. RESULTS Of the 172 participants included in this analysis, 21 (12.2%) had HbA(1C) concentrations above the cutoff of 5.7 used to identify pre-diabetes. None (0%) of these 21 participants, however, were observed to have a glucose concentration above the pre-diabetes cutoff of 110 mg/dl, and only 13 of 21 participants had HOMA-IR above the pre-diabetes cutoff of 2.5. When compared to the previously identified glucose cutoff of 110 mg/dl and HOMA-IR cutoff of 2.5 for pre-diabetes, HbA(1C) showed high specificity (88 and 93%, respectively) but very low sensitivity (0 and 21%, respectively). Glucose, insulin and HOMA-IR were significantly interrelated, but HbA(1C) was not significantly correlated with these biochemical prediabetes assessment variables, nor with anthropometric (BMIz, WC) risk factors. CONCLUSION Our results suggest that HbA(1C) had poor discrimination power to identify prediabetes in overweight and obese 9- to 11-year-old African American children. Future studies are recommended to compare the feasibility, sensitivity and predictive power of different screening tests currently recommended to avoid inadequacy when screening for prediabetes and diabetes.

Abstract
OBJECTIVE Non-diabetic African American (AA) youth have an upregulated insulin secretion relative to insulin sensitivity (IS) compared with their American White (AW) peers. We investigated if similar racial differences exist in youth with T2DM. RESEARCH DESIGN AND METHODS Fourteen AAs and 14 AWs T2DM adolescents underwent evaluation of IS and clearance (hyperinsulinemic-euglycemic clamp), first- and second-phase insulin and C-peptide secretion (hyperglycemic clamp); body composition (DEXA); and abdominal adiposity (CT). RESULTS AA and AW T2DM had similar HbA1c, diabetes duration, BMI, and % body fat, with lower visceral fat in AAs (p = 0.013). While insulin-stimulated glucose disposal was similar in AA and AW (7.5 ± 1.0 vs. 7.3 ± 0.9 mg/kg FFM/min), IS tended to be lower (2.5 ± 0.4 vs. 3.8 ± 0.6 mg/kg FFM/min per µU/mL, p = 0.081). First-phase insulin (175.7 ± 52.9 vs. 66.6 ± 10.8 µU/mL, p = 0.01) and second-phase insulin (236.2 ± 40.7 vs. 105.1 ± 17.9 µU/mL, p = 0.008), and first-phase C-peptide (8.2 ± 1.2 vs. 5.0 ± 0.3 ng/mL, p = 0.02) and second-phase C-peptide (10.8 ± 0.9 vs. 7.6 ± 0.6 ng/mL, p = 0.012) were higher in AA. β-Cell function relative to IS was higher in AA vs. AW (259.5 ± 35.3 vs. 168.8 ± 25.1 mg/kg FFM/min, p = 0.043). CONCLUSIONS Racial differences in insulin secretion can be demonstrated with the clamp technique in obese adolescents with T2DM. Similar to non-diabetic youth, AA adolescents with T2DM compared with their AW counterparts have an upregulated β-cell function relative to IS, the reasons for which remain to be investigated.

Abstract
AIMS/HYPOTHESIS To determine the impact of maternal diabetes during pregnancy on racial disparities in fetal growth. METHODS Using linked birth certificate, inpatient hospital and prenatal claims data we examined live singleton births of mothers resident in South Carolina who self-reported their race as non-Hispanic white (NHW; n = 140,128) or non-Hispanic black (NHB; n = 82,492) and delivered at 28-42 weeks' gestation between 2004 and 2008. RESULTS Prepregnancy diabetes prevalence was higher in NHB (3.0%) than in NHW (1.7%), while the prevalence of gestational diabetes mellitus (GDM) was similar in NHB (6.1%) and NHW (6.3%). At a delivery BMI of 35 kg/m(2), GDM exposure was associated with an average birthweight only 17 g (95% CI 4, 30) higher in NHW, but 78 g (95% CI 61, 95) higher in NHB (controlling for gestational age, maternal age, infant sex and availability of information on prenatal care). Figures for prepregnancy diabetes were 58 g (95% CI 34, 81) in NHW and 60 g (95% CI 37, 84) in NHB. GDM had a greater impact on birthweight in NHB than in NHW (60 g racial difference [95% CI 39, 82]), while prepregnancy diabetes had a large but similar impact. Similarly, the RR for GDM of having a large- relative to a normal-weight-for-gestational-age infant was lower in NHW (RR 1.41 [95% CI 1.34, 1.49]) than in NHB (RR 2.24 [95% CI 2.05, 2.46]). CONCLUSIONS/INTERPRETATION These data suggest that the negative effects of GDM combined with obesity during pregnancy may be greater in NHB than in NHW individuals.

Abstract
OBJECTIVE Type 2 diabetes mellitus in children and adolescents has become an important public health concern, in parallel with the "epidemic" of overweight/obesity in this age group and a sharp increase in children being prescribed antidepressant or antipsychotic medications. In children and adolescents, the prevalence of being prescribed antidepressant or antipsychotic medications was examined as well as the association of these medications with developing type 2 diabetes mellitus. METHOD A retrospective cohort design evaluating South Carolina Medicaid medical and pharmacy claims between January 1, 1996, and December 31, 2006, was employed to identify 4,070 children and adolescents diagnosed initially with type 2 diabetes mellitus, 39% of whom were later reclassified as type 1 (using ICD-9 criteria). The added risk of developing type 2 diabetes mellitus posed by the use of antidepressants or antipsychotics was investigated in this cohort, controlling for individual risk factors and comorbid cardiometabolic conditions. RESULTS Use of antidepressants or antipsychotics alone, or the 2 in combination, conferred an increased risk (1.3 to 2 times greater) of having diagnosed type 2 diabetes mellitus and several comorbid cardiometabolic conditions (obesity, dyslipidemia, and hypertension). However, psychiatric illnesses generally developed and were treated after the initial development of diabetes. CONCLUSIONS Depression was diagnosed and treated in 10% to 20% of this cohort. While antidepressants and antipsychotics, alone or in combination, are associated with a diagnosis of type 2 diabetes mellitus and its cardiometabolic comorbidities by adolescence, they do not appear to be an explanatory factor in the early onset of type 2 diabetes mellitus in this age group and do not appear to cloud the initial, overlapping clinical picture between type 1 and type 2 diabetes mellitus.

Abstract
Over the past 2 decades, the prevalence of obesity and type 2 diabetes mellitus (T2DM) in children and adolescents has risen to epidemic proportions and disproportionately affects racial and ethnic minorities, who are at greater risk. The pathophysiology of T2DM is complex and involves insulin resistance, pancreatic β-cell dysfunction, and visceral adiposity. Current treatments of T2DM are limited to lifestyle intervention, metformin, and insulin therapy; use of these strategies in combination is often most effective. The role of research is to uncover simple biomarkers for insulin sensitivity and optimal and innovative treatment of insulin resistance and T2DM.

Abstract
PURPOSE The purpose of this study was to identify and assess health behaviors among ethnic minority children at high risk for type 2 diabetes. METHODS Diabetes screenings were conducted at community centers, churches, and local neighborhood health fairs in Madison, Wisconsin. During these events, diabetes risk assessment surveys were given to parents of children between the ages of 10 to 19 years. Parents who identified their children as having 2 or more risk factors for type 2 diabetes were invited to have their child screened for type 2 diabetes. RESULTS A total of 86 children between the ages of 10 to 19 years (mean age = 13; 58% male) were screened for diabetes. Fifty-one percent of the children were overweight or obese with 38% having >3 risk factors for type 2 diabetes. While there was no significant difference in the nutritional habits reported between normal, overweight, or obese children, fewer overweight and obese children reported exercising at least 30 minutes 5 to 7 days a week compared to children with a normal weight (P = .033). CONCLUSION Prevention of diabetes is a powerful public health intervention. Targeted diabetes screening in disadvantaged, underserved communities is an effective way to identify families with children at risk for type 2 diabetes. In addition, information obtained from these screenings can assist researchers and clinicians in designing accessible and affordable health promotion interventions that are culturally relevant to the youth and families within the community.

Abstract
OBJECTIVE To describe an etiologic approach to classification of diabetes types in youth based on the 1997 American Diabetes Association (ADA) framework, using data from the SEARCH for Diabetes in Youth Study. RESEARCH DESIGN AND METHODS SEARCH conducted a comprehensive assessment of 2,291 subjects aged <20 years with recently diagnosed diabetes. Using autoimmunity (at least one of two diabetes autoantibodies) and insulin sensitivity (equation validated against hyperinsulinemic-euglycemic clamps) as the main etiologic markers, we described four categories along a bidimensional spectrum: autoimmune plus insulin-sensitive (IS), autoimmune plus insulin-resistant (IR), nonautoimmune plus IS, and nonautoimmune plus IR. We then explored how characteristics, including genetic susceptibility to autoimmunity (HLA genotypes), insulin deficiency, and clinical factors varied across these four categories. RESULTS Most subjects fell into either the autoimmune plus IS (54.5%) or nonautoimmune plus IR categories (15.9%) and had characteristics that align with traditional descriptions of type 1 or type 2 diabetes. The group classified as autoimmune plus IR (19.5%) had similar prevalence and titers of diabetes autoantibodies and similar distribution of HLA risk genotypes to those in the autoimmune plus IS group, suggesting that it includes individuals with type 1 diabetes who are obese. The group classified as nonautoimmune plus IS (10.1%) likely includes individuals with undetected autoimmunity but may also include those with monogenic diabetes and thus requires further testing. CONCLUSIONS The SEARCH study offers researchers and clinicians a practical application for the etiologic classification of diabetes type and at the same time identifies a group of youths who would benefit from further testing.

Abstract
OBJECTIVE In adults, elevated levels of retinol binding protein 4 (RBP4) have been associated with biochemical markers of adiposity-related co-morbidities including insulin resistance, dyslipidemia, hypertension, and abdominal obesity. This study examined the relationship between RBP4 and risk factors for co-morbidities of adiposity in a population of ethnically diverse children in early- to mid-adolescence in the public school system of New York City. MATERIALS/METHODS We analyzed anthropometric (body mass index, % body fat, waist circumference), metabolic (lipids, glucose), and inflammatory (TNF-alpha, interleukin-6, C-reactive protein, adiponectin) markers for adiposity-related co-morbidities and serum alanine aminotransferase (ALT) in 106 school children (65 males, 41 females) 11-15 years of age (mean +/- SD = 13.0 +/- 0.1 years) who were enrolled in the Reduce Obesity and Diabetes (ROAD) project. Insulin sensitivity was assessed by quantitative insulin sensitivity check index. Insulin secretory capacity was measured as acute insulin response and glucose disposal index. RESULTS Serum RBP4 was significantly correlated directly with ALT, triglycerides, and triglyceride z-score, and inversely correlated with adiponectin. Correlations with ALT and adiponectin remained significant when corrected for % body fat, age, and gender. There were significant ethnic differences in the relationship of RBP4 to ALT, glucose disposal index and adiponectin. CONCLUSIONS In early- to mid-adolescents, circulating concentrations of RBP4 are correlated with multiple risk factors for adiposity-related co-morbidities. The observation that many associations persisted when corrected for % body fat, suggests that RBP4 can be viewed as an independent marker of adiposity-related co-morbidity risk in children.

Abstract
OBJECTIVE To determine if pretreatment insulin and C-peptide levels together with antibody status are predictive of HbAlc levels before and during therapy in obese African-American youth with type 2 diabetes. METHODS Records of African-American patients with clinical diagnosis of type 2 diabetes were retrospectively analyzed. Insulin, C-peptide, blood glucose, HbA1c and islet autoantibodies at diagnosis were recorded. These variables were compared with HbA1c levels during therapy. RESULTS Eight of 45 patients were islet autoantibody positive. There was no difference in age, Body Mass Index z-score, insulin, C-peptide, glucose or HbAlc levels between antibody positive or negative patients. Insulin (r = -0.45, p < 0.01 n=45) and C-peptide (r = -0.59, p < 0.001, n=36) were correlated with HbA1c at diagnosis but not during therapy. CONCLUSIONS Higher insulin levels were associated with lower HbA1c at presentation but not during therapy. Antibody status was not associated with differences in insulin, C-peptide levels or HbAlc level.

Abstract
Diabetes mellitus is one of the most common severe chronic diseases of childhood. Much of our knowledge of the epidemiology of diabetes in young people has been generated by large collaborative efforts based on standardized registry data, such as the DIAMOND Project worldwide and the EURODIAB study in Europe. These registries showed that although at the start of the 20th century childhood diabetes was rare, by the end of the century a steady increase in incidence had been reported in many parts of the world. However, epidemiologic data for temporal trends in pediatric diabetes are still lacking or are minimal for most of the global population of youth, including in the United States. In addition, the epidemiology of diabetes in youth is changing. As youth are becoming increasingly overweight, we are seeing more obese children with a clinical phenotype of type 2 diabetes or "adult-onset" diabetes. It is imperative that efforts directed at surveillance of diabetes in young people continue and expand, not only to understand its complex etiology, but also because of its increasing public health importance.

Abstract
OBJECTIVE To determine the frequency of islet cell autoimmunity in youth clinically diagnosed with type 2 diabetes and describe associated clinical and laboratory findings. RESEARCH DESIGN AND METHODS Children (10-17 years) diagnosed with type 2 diabetes were screened for participation in the Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study. Measurements included GAD-65 and insulinoma-associated protein 2 autoantibodies using the new National Institute of Diabetes and Digestive and Kidney Diseases/National Institutes of Health (NIDDK/NIH) standardized assays, a physical examination, and fasting lipid, C-peptide, and A1C determinations. RESULTS Of the 1,206 subjects screened and considered clinically to have type 2 diabetes, 118 (9.8%) were antibody positive; of these, 71 (5.9%) were positive for a single antibody, and 47 were positive (3.9%) for both antibodies. Diabetes autoantibody (DAA) positivity was significantly associated with race (P < 0.0001), with positive subjects more likely to be white (40.7 vs. 19%) (P < 0.0001) and male (51.7 vs. 35.7%) (P = 0.0007). BMI, BMI z score, C-peptide, A1C, triglycerides, HDL cholesterol, and blood pressure were significantly different by antibody status. The antibody-positive subjects were less likely to display characteristics clinically associated with type 2 diabetes and a metabolic syndrome phenotype, although the range for BMI z score, blood pressure, fasting C-peptide, and serum lipids overlapped between antibody-positive and antibody-negative subjects. CONCLUSIONS Obese youth with a clinical diagnosis of type 2 diabetes may have evidence of islet autoimmunity contributing to insulin deficiency. As a group, patients with DAA have clinical characteristics significantly different from those without DAA. However, without islet autoantibody analysis, these characteristics cannot reliably distinguish between obese young individuals with type 2 diabetes and those with autoimmune diabetes.

Abstract
The aim of this study was to evaluate the relationship between intakes of subgroups of energy-providing carbohydrate, and markers of cardiometabolic risk factors in high BMI African American (AA) children. A cross sectional analysis was performed on data from a sample of 9-11 year old children (n = 95) with BMI greater than the 85th percentile. Fasting hematological and biochemical values for selected markers of cardiometabolic risk factors were related to intakes of carbohydrates and sugars. After adjusting for gender, pubertal stage and waist circumference, multivariate regression analysis showed that higher intakes of carbohydrate (with fat and protein held constant) were associated with higher plasma concentrations of triglycerides (TG), VLDL-C, IDL-C, and worse insulin resistance (homeostasis model assessment of insulin resistance, HOMA-IR). After dividing carbohydrate into non-sugar versus sugar fractions, sugars were significantly related to higher TG, VLDL-C, IDL-C, lower adipocyte fatty acid insulin sensitivity (ISI-FFA), and was closely associated with increased HOMA-IR. Similar trends were observed for sugars classified as added sugars, and for sugars included in beverages. Further dividing sugar according to the food group from which it was consumed showed that consuming more sugar from the candy/soda food group was highly significantly associated with increased TG, VLDL-C, IDL-C and closely associated with increased HOMA-IR. Sugars consumed in all fruit-containing foods were significantly associated with lower ISI-FFA. Sugars consumed as fruit beverages was significantly associated with VLDL-C, IDL-C and ISI-FFA whereas sugars consumed as fresh, dried and preserved fruits did not show significant associations with these markers. Sugars consumed from in all dairy foods were significantly associated with higher TG, VLDL-C and IDL-C, and with significantly lower HDL-C and ISI-FFA. These effects were associated with sugars consumed in sweetened dairy products, but not with sugars consumed in unsweetened dairy products. This analysis suggests that increases in carbohydrate energy, especially in the form of sugar, may be detrimental to cardiometabolic health in high BMI children.

Abstract
OBJECTIVE Obesity's association with type 2 diabetes (T2DM) is well established, but is less clear with type 1 diabetes (T1DM). We calculated the prevalence of overweight and obesity among diabetic youth in the USA from a six-center, population-based study of racially and ethnically diverse youth with diabetes, and we compared these rates with estimates among nondiabetic youth. DESIGN/SETTING Diabetic participants were examined in 2001-2004 for the SEARCH for Diabetes in Youth study (SEARCH) and nondiabetic participants were examined during the same years of the National Health and Nutrition Examination Survey (NHANES). PARTICIPANTS 3953 diabetic youth and 7666 nondiabetic youth aged 3-19 yr. MAIN OUTCOME MEASURES Overweight was defined as body mass index (BMI) from the 85th to <95th percentile for age and sex and obesity defined as > or = 95th percentile. Diabetes type was categorized as T1DM or T2DM based on physician diagnosis. RESULTS Among youth with T2DM, the prevalence of overweight was 10.4% and obesity was 79.4%. Among youth with T1DM, 22.1% were overweight. The prevalence of overweight among youth with T1DM was higher than among those without diabetes overall (22.1% vs. 16.1%) (P <.05). The obesity rate for T1DM was 12.6% overall (range Non-Hispanic White 10.7%-African-American 20.1%). CONCLUSIONS As expected, most of the youth with T2DM were obese. Youth with T1DM had a higher prevalence of overweight, but not of obesity, than nondiabetic youth. Future studies of obesity among youth with diabetes of all types will further our understanding of the impact of obesity on diabetes both as a risk factor and a comorbidity.

Abstract
BACKGROUND The aim of this study was to evaluate the relationship between intakes of energy-providing macronutrients, and markers of cardio metabolic risk factors in high BMI African American (AA) children. METHODS A cross sectional analysis of a sample of 9-11 year old children (n = 80) with BMI greater then the 85th percentile. Fasting hematological and biochemical measurements, and blood pressure were measured as selected markers of cardio metabolic risk factors and their relationships to dietary intakes determined. RESULTS After adjusting for gender, pubertal stage and waist circumference (WC), multivariate regression analysis showed that higher total energy intakes (when unadjusted for source of energy) were associated with higher plasma concentrations of intermediate density lipoprotein cholesterol (IDL-C) and very low density lipoprotein cholesterol (VLDL-C). Higher intakes of carbohydrate energy (fat and protein held constant) were associated with higher IDL-C, VLDL-C, triglycerides (TG) and homeostasis model assessment of insulin resistance (HOMA-IR). Higher intakes of fat (carbohydrate and protein held constant), however, were associated with lower IDL-C; and higher protein intakes (fat and carbohydrate held constant) were associated with lower HOMA-IR. CONCLUSION The specific macronutrients that contribute energy are significantly associated with a wide range of cardio metabolic risk factors in high BMI AA children. Increases in carbohydrate energy were associated with undesirable effects including increases in several classes of plasma lipids and HOMA-IR. Increases in protein energy were associated with the desirable effect of reduced HOMA-IR, and fat energy intakes were associated with the desirable effect of reduced IDL-C. This analysis suggests that the effect of increased energy on risk of developing cardio metabolic risk factors is influenced by the source of that energy.

Abstract
Diabetes mellitus is a growing problem in all parts of the world. Both clinical trials and animal models of type I and type II diabetes have shown that hyperactivity of angiotensin-II (Ang-II) signaling pathways contribute to the development of diabetes and diabetic complications. Of clinical relevance, blockade of the renin-angiotensin system prevents new-onset diabetes and reduces the risk of diabetic complications. Angiotensin-converting enzyme (ACE) 2 is a recently discovered mono-carboxypeptidase and the first homolog of ACE. It is thought to inhibit Ang-II signaling cascades mostly by cleaving Ang-II to generate Ang-(1-7), which effects oppose Ang-II and are mediated by the Mas receptor. The enzyme is present in the kidney, liver, adipose tissue and pancreas. Its expression is elevated in the endocrine pancreas in diabetes and in the early phase during diabetic nephropathy. ACE2 is hypothesized to act in a compensatory manner in both diabetes and diabetic nephropathy. Recently, we have shown the presence of the Mas receptor in the mouse pancreas and observed a reduction in Mas receptor immuno-reactivity as well as higher fasting blood glucose levels in ACE2 knockout mice, indicating that these mice may be a new model to study the role of ACE2 in diabetes. In this review we will examine the role of the renin-angiotensin system in the physiopathology and treatment of diabetes and highlight the potential benefits of the ACE2/Ang-(1-7)/Mas receptor axis, focusing on recent data about ACE2.

Abstract
Type 2 diabetes mellitus (T2DM) in children and adolescents is an important Public Health problem against the backdrop of the epidemic of childhood obesity. The clinical presentation of T2DM in youth is heterogeneous from minimal symptomatology to diabetic ketoacidosis. The increasing rates of youth T2DM have paralleled the escalating rates of obesity, which is the major risk factor impacting insulin sensitivity. Additional risk factors include minority race, family history of diabetes mellitus, maternal diabetes during pregnancy, pubertal age group and conditions associated with insulin resistance (IR) - such as polycystic ovary syndrome (PCOS). The pathophysiology of T2DM has been studied extensively in adults, and it is widely accepted that IR together with beta-cell failure are necessary for the development of clinical diabetes mellitus in adulthood. However, pathophysiologic studies in youth are limited and in some cases conflicting. Similar to adults, IR is a prerequisite, but beta-cell failure is necessary for progression from normal glucose tolerance to prediabetes and frank diabetes in youth. Even though rates of T2DM in youth are increasing, the overall prevalence remains low if compared with type 1 diabetes mellitus (T1DM). However, as youth with T1DM are becoming obese, the clinical distinction between T2DM and obese T1DM has become difficult, because of the overlapping clinical picture with evidence of islet cell autoimmunity in a significant proportion of clinically diagnosed youth with T2DM. The latter are most likely obese children with autoimmune T1DM who carry a misdiagnosis of T2DM. Further research is needed to probe the pathophysiological, immunological, and metabolic differences between these two groups in the hopes of assigning appropriate therapeutic regimens. These challenges combined with the evolving picture of youth T2DM and its future complications provide unending opportunities for acquisition of new knowledge in the field of childhood diabetes.
