BACKGROUND: Impaired microvascular insulin signaling may develop prior to overt indices of microvascular endothelial dysfunction and represent an early pathological feature of adolescent obesity. Using a translational porcine model of juvenile obesity, we tested the hypotheses that in the early stages of obesity development, impaired insulin signaling manifests in skeletal muscle (triceps), brain (prefrontal cortex) and corresponding vasculatures, and that depressed insulin-induced vasodilation is reversible with acute inhibition of protein kinase C beta (PKCβ)...

BACKGROUND: Idiopathic genu valgum is a frequently diagnosed growth disorder in adolescence. Whenever the possibilities of conservative therapy have been exhausted, leg straightening by means of hemiepiphysiodesis has become the standard form of treatment. Because of their flexible screw-plate connection, eight-Plates have been reported in the literature to lead to lower complications regarding implant loosening and fracture compared to other implants. The aim of this retrospective survey was to analyse our own patient population who were treated for genu valgum by means of temporary hemiepiphysiodesis near the knee using eight-Plates to modulate growth...

BackgroundIncreased self-perceived fatigue (SpF) has already been identified in chronic conditions such as obesity, but it is also a growing problem in school-attending adolescents (±25%). This study tried to link body composition to SpF and physical activity/performance. Additionally, indicators for fatigue were determined.MethodsA total of 452 adolescents were recruited. Body composition was measured and physical activity, physical performance, and SpF were assessed. Based on the total SpF (Multidimensional Fatigue Inventory) outcomes, three groups were created: low fatigue (LF) medium fatigue (MF) and high fatigue (HF)...

REVIEW
Gagan Priya, Sanjay Kalra
There is a rising trend of overweight and obesity among individuals with type 1 diabetes. This is often associated with insulin resistance, increased insulin dose requirements and poor glycemic control. Insulin resistance is also seen during puberty and is strongly related to increased risk of cardiovascular disease. The role of metformin as an adjunct to ongoing intensive insulin therapy in type 1 diabetics has been evaluated in several randomized trials, including the recently concluded T1D Exchange Network trial in adolescents and the REMOVAL trial in adults...

OBJECTIVES: In 2007, 31.7% of Georgia adolescents in grades 9-12 were overweight or obese. Understanding the impact of policies and interventions on obesity prevalence among young people can help determine statewide public health and policy strategies. This article describes a systems model, originally launched in 2008 and updated in 2014, that simulates the impact of policy interventions on the prevalence of childhood obesity in Georgia through 2034. METHODS: In 2008, using information from peer-reviewed reports and quantitative estimates by experts in childhood obesity, physical activity, nutrition, and health economics and policy, a group of legislators, legislative staff members, and experts trained in systems thinking and system dynamics modeling constructed a model simulating the impact of policy interventions on the prevalence of childhood obesity in Georgia through 2034...

Physical inactivity among children is a public health problem associated with low levels of fitness, obesity, and increased risk of chronic diseases. Public health experts have identified policies targeting physical activity as a promising strategy to address this challenge. Understanding the process by which such policies are adopted may help to facilitate progress nationally. To examine lessons learned from the passage of the Student Health and Physical Education Act in Georgia, we conducted 15 interviews with people engaged in the adoption of the act...

OBJECTIVES: The FitnessGram Healthy Fitness Zone continuum (HFZc) score reflects the relative difference of a person's body mass index (BMI) from the established FitnessGram standard. As such, it may provide added utility for public health programming and research on obesity among school-aged children and adolescents. We used the standard BMI Z (BMIz) score and the alternative HFZc score to describe changes in BMI of school-aged children and adolescents in Georgia over time. METHODS: We compiled 2012-2014 BMI data from the Georgia FitnessGram database...

PURPOSE OF REVIEW: Although childhood obesity has leveled off in the last decade, 'severe obesity' continues to be on the rise. Various genetic, environmental and hormonal factors contribute to obesity. This article reviews the most current understanding of obesity's multifactorial origin and recent recommendations for its management in childhood and adolescence. RECENT FINDINGS: Epigenetics plays a key role in transmitting obesity risk to offspring. Single-nucleotide polymorphisms at genetic loci for adipokines and their receptors are associated with obesity...

INTRODUCTION: Research shows that adolescents who are overweight or obese may be at greater risk of cigarette smoking, and that this relationship may vary by gender. However, this relationship is understudied for electronic cigarettes (e-cigarettes). Given the high rate of adolescent obesity and the rise in e-cigarette use in adolescents, this relationship should be investigated. METHODS: Data are from the third wave (collected October 2015-January 2016) of the Texas Adolescent Tobacco and Marketing Surveillance system...

Microalbuminuria (MA) is a well-known predictor of cardiovascular disease and mortality in adults. However, these relationships remain unclear in adolescents. A few studies on association between MA and obesity have been conducted in adolescents. However, the association between MA and growth parameters such as height has not been studied, despite the fact that adolescence is a period of rapid physiological change. We, therefore, aimed to evaluate the association between MA and growth parameters, and the association between MA and obesity related cardiovascular risk factors after adjusting for growth...

Adolescence is a stage in the life course during which youth become more autonomous in their health behaviors. Overweight and obesity during this developmental period are associated with short- and long-term physical and emotional morbidity, and African American youth are at pronounced risk for these health outcomes. The style of parenting employed by caregivers influences health behaviors in children, though the persistence of this influence into adolescence is not clear. This study examined associations among caregiver feeding practices, body mass index z-score (zBMI), and waist circumference (WC) in a cohort of 212 African American adolescents (50...

Retinol-binding protein 4 (RBP4) is an emerging risk factor for atherosclerotic disease in adults. However, to our knowledge, there are no studies examining the relationship between RBP4 and cardiovascular risk in young population. Therefore, we aimed to estimate this potential relationship in overweight/obese adolescent girls. Seventy overweight/obese adolescent girls, mean age 17.6±1.20 years, were included. Anthropometric and biochemical parameters were measured. Cardiovascular risk score (CVRS) was calculated by adding points for each risk factor (e...
