Health care professionals face problems managing obesity and often fail to follow guidelines for its management in practice. Only a few single-country reports are available describing delivery of primary care to children with obesity.

Nearly all primary pediatric care providers from 4 European countries recognize the importance of obesity in pediatric practice, but only half use BMI clinically, and many lack the confidence and the infrastructure needed for providing care to patients with obesity. (Read the full article)

The number of overweight and obese children has dramatically increased in recent decades. To combat this trend, information on possible gender-related differences in risk factors of overweight and obesity is critical.

This study examines associations of gender and physiologic and behavior measurements with potential cardiovascular risk. Lunch consumption and screen time were associated with weight; however, other associations with weight differ by gender. This information can be used to tailor future interventions.

Adverse effects of excess weight are likely related to both obesity severity and duration. Little is known about the contribution of adolescent weight status to development of specific comorbid conditions in adults.

Severe obesity at age 18 was independently associated with increased risk of lower extremity venous edema, walking limitation, kidney dysfunction, polycystic ovary syndrome, respiratory conditions, diabetes, and hypertension in adulthood. (Read the full article)

One study examined the incidence of obesity among low-income children aged <5 years who participated in federally funded child health and nutrition programs during 1985–1990. The study examined the variations by baseline age but not by gender or race/ethnicity.

This study provides most recent data on incidence and reversing of obesity and variations across gender, baseline age, and racial/ethnic subgroups among young low-income children. We conducted multivariable analyses to examine the relative risk of obesity in population subgroups. (Read the full article)

Childhood obesity poses a serious threat to human health. Obesity is caused by genetic and environmental factors and linked to type 2 diabetes and cardiovascular disease. Pediatric obesity cohorts aim at understanding early events in the pathophysiology of obesity-related complications.

Cohort subjects are examined at consecutive visits, including measurements of glucose tolerance and hormones regulating nutrient handling (enhanced glucose tolerance tests) and body composition (MRI and bioimpedance). Mechanisms causing obese children to progress to type 2 diabetes are delineated. (Read the full article)

Maternal prepregnancy obesity is associated with an increased risk of neurodevelopmental disorders in children, but previous studies have not taken paternal obesity into account. This has precluded differentiation between the effects of intrauterine exposures and potential genetic associations.

Robust associations were demonstrated between paternal obesity and the risk of autistic disorder and Asperger disorder in children. This study is the first to implicate paternal obesity as a risk factor for autism, and replication is warranted. (Read the full article)

Previous studies showed that prevalence of abdominal obesity among US children and adolescents increased significantly between 1988–1994 and 2003–2004. However, little is known about recent time trends in abdominal obesity since 2003–2004.

In 2011–2012, 17.95% of children and adolescents aged 2 to 18 years were abdominally obese defined by waist circumference. The prevalence of abdominal obesity leveled off among US children and adolescents from 2003–2004 to 2011–2012. (Read the full article)

Adolescent males from low-income communities are a group at increased risk of obesity and related health concerns. Obesity prevention interventions targeting adolescents have so far had mixed success. Targeted interventions, tailored for specific groups, may be more appealing and efficacious.

A multicomponent school-based intervention using smartphone technology can improve muscular fitness, movement skills, and key weight-related behaviors among low-income adolescent boys. (Read the full article)

Family meals are protective for child health, but there are inconsistent findings in relation to child weight status. More research is needed examining why family meals are protective for child health and whether there are differences by child weight status.

The current mixed-methods study used direct observational methods to examine family dynamics during family meals and child weight status. Results indicated that positive family interpersonal and food-related dynamics during family meals were associated with reduced prevalence of childhood obesity. (Read the full article)

The built environment may affect weight status by presenting opportunities or barriers for exercise and nutritious eating. Although there is substantial cross-sectional evidence linking neighborhood factors and childhood obesity, causal uncertainty remains, owing to conceptual and methodological challenges.

This prospective study examined neighborhood influences on obesity during the transition to adolescence, a sensitive period for excess weight gain. Girls living in neighborhoods characterized by physical disorder or increased access to food and service retailers exhibited higher obesity risk. (Read the full article)

Obesity among youth can have immediate health effects as well as longer-term consequences during adulthood. Overweight/obese children and adolescents are much more likely than normal-weight children to become overweight/obese adults.

This large, multisite longitudinal study examines patterns of exit from and entry into obesity between childhood and adolescence. Socioeconomic factors, body image, television habits, and parental obesity were important predictors of whether children remained obese or became obese. (Read the full article)

Motivational interviewing (MI) has been found to increase the effectiveness of weight loss programs in obese children and adolescents. Although parental involvement seems to be linked to its effectiveness, strong conclusions cannot be drawn.

The present study found that MI with parental involvement is an effective strategy in changing obesity-related outcomes and has additional effects beyond MI with adolescents only. These findings are important when administering MI interventions in school settings. (Read the full article)

Childhood obesity rates in the United States remain at historic highs. The pediatric primary care office represents an important, underutilized source of intervention. There is a need to test the efficacy of motivational interviewing for pediatric obesity in primary care.

This is among the first large-scale randomized trials to show significant reductions in BMI and that motivational interviewing, delivered by trained providers in the primary care setting, can be an important and feasible part of addressing childhood obesity. (Read the full article)

Insulin resistance plays a role in obesity. Recently it has been associated with increased risk of AD. Aβ42 and PSEN1 are molecules associated with increased risk of later AD. Patients affected by AD show elevated levels of plasma Aβ42.

Levels of Aβ42 and PSEN1 are significantly elevated in obese adolescents and correlated with the degree of both adiposity and systemic insulin resistance. (Read the full article)

"Protective" complementary feeding practices that promote self-regulation of intake and development of healthy food preferences have been positively associated with healthy child eating patterns and growth. There are few high-quality trials evaluating feeding practice interventions; none has reported long-term outcomes.

This large randomized controlled trial demonstrates that anticipatory guidance on the "how" of complementary feeding resulted in more protective feeding practices. These intervention effects were sustained for 3 years and translated into commensurate trends in obesity risk. (Read the full article)

Although treatment programs for childhood obesity can demonstrate success, long-term outcomes have seldom been evaluated. The benefit of intervention when overweight is identified in a screening assessment and parental recognition of the problem is minimal is understudied.

A low-dose (sessions every 1–3 months), but long-term (2 years), family-based intervention was effective at reducing BMI compared with usual care in children recruited via a weight screening initiative in which many parents had been unaware their child was overweight. (Read the full article)

Children and adolescents with autism spectrum disorders (ASDs) may be at elevated risk for unhealthy weight. Samples of children with verified clinical diagnoses of ASD have been lacking, and associations with child behavior and functioning are not well understood.

Young children (2–5 years old) and adolescents (12–17 years old) with ASDs were at an elevated risk for unhealthy weight status compared with a general population sample. The presence of sleep or affective problems may confer increased risk among those with ASD. (Read the full article)

The following is intended to clarify how weight can be controlled when hunger is kept at bay using a reliable, informative tool called the glycemic index.

ABSTRACT

Obesity is associated with increased disease severity, elevated viral titers in exhaled breath, and significantly prolonged viral shed during influenza A virus infection. Due to the mutable nature of RNA viruses, we questioned whether obesity could also influence influenza virus population diversity. Here, we show that minor variants rapidly emerge in obese mice. The variants exhibit increased viral replication, resulting in enhanced virulence in wild-type mice. The increased diversity of the viral population correlated with decreased type I interferon responses, and treatment of obese mice with recombinant interferon reduced viral diversity, suggesting that the delayed antiviral response exhibited in obesity permits the emergence of a more virulent influenza virus population. This is not unique to obese mice. Obesity-derived normal human bronchial epithelial (NHBE) cells also showed decreased interferon responses and increased viral replication, suggesting that viral diversity also was impacted in this increasing population.

IMPORTANCE Currently, 50% of the adult population worldwide is overweight or obese. In these studies, we demonstrate that obesity not only enhances the severity of influenza infection but also impacts viral diversity. The altered microenvironment associated with obesity supports a more diverse viral quasispecies and affords the emergence of potentially pathogenic variants capable of inducing greater disease severity in lean hosts. This is likely due to the impaired interferon response, which is seen in both obese mice and obesity-derived human bronchial epithelial cells, suggesting that obesity, aside from its impact on influenza virus pathogenesis, permits the stochastic accumulation of potentially pathogenic viral variants, raising concerns about its public health impact as the prevalence of obesity continues to rise.

ABSTRACT

Obesity and associated metabolic disorders are worldwide public health issues. The gut microbiota plays a key role in the pathophysiology of diet-induced obesity. Glycerol monolaurate (GML) is a widely consumed food emulsifier with antibacterial properties. Here, we explore the anti-obesity effect of GML (1,600 mg/kg of body weight) in high-fat diet (HFD)-fed mice. HFD-fed mice were treated with 1,600 mg/kg GML. Integrated microbiome, metabolome, and transcriptome analyses were used to systematically investigate the metabolic effects of GML, and antibiotic treatment was used to assess the effects of GML on the gut microbiota. Our data indicated that GML significantly reduced body weight and visceral fat deposition, improved hyperlipidemia and hepatic lipid metabolism, and ameliorated glucose homeostasis and inflammation in HFD-fed mice. Importantly, GML modulated HFD-induced gut microbiota dysbiosis and selectively increased the abundance of Bifidobacterium pseudolongum. Antibiotic treatment abolished all the GML-mediated metabolic improvements. A multiomics (microbiome, metabolome, and transcriptome) association study showed that GML significantly modulated glycerophospholipid metabolism, and the abundance of Bifidobacterium pseudolongum strongly correlated with the metabolites and genes that participated in glycerophospholipid metabolism. Our results indicated that GML may be provided for obesity prevention by targeting the gut microbiota and regulating glycerophospholipid metabolism.

OBJECTIVE

Most individuals with type 2 diabetes also have obesity, and treatment with some diabetes medications, including insulin, can cause further weight gain. No approved chronic weight management medications have been prospectively investigated in individuals with overweight or obesity and insulin-treated type 2 diabetes. The primary objective of this study was to assess the effect of liraglutide 3.0 mg versus placebo on weight loss in this population.

BackgroundA brief intervention whereby GPs opportunistically facilitate an NHS-funded referral to a weight loss programme is clinically and cost-effective.AimTo test the acceptability of a brief intervention and attendance at a weight loss programme when GPs facilitate a referral that requires patients to pay for the service.Design and settingAn observational study of the effect of a GP encouraging attendance at a weight loss programme requiring self-payment in the West Midlands from 16 October 2018 to 30 November 2018, to compare with a previous trial in England in which the service was NHS-funded.MethodSixty patients with obesity who consecutively attended primary care appointments received an opportunistic brief intervention by a GP to endorse and offer a referral to a weight loss programme at the patient’s own expense. Participants were randomised to GPs who either stated the weekly monetary cost of the programme (basic cost) or who compared the weekly cost to an everyday discretionary item (cost comparison). Participants were subsequently asked to report whether they had attended a weight loss programme.ResultsOverall, 47% of participants (n = 28) accepted the referral; 50% (n = 15) in the basic cost group and 43% (n = 13) in the cost comparison group. This was significantly less than in a previous study when the programme was NHS-funded (77%, n = 722/940; P<0.0001). Most participants reported the intervention to be helpful/very helpful and appropriate/very appropriate (78%, n = 46/59 and 85%, n = 50/59, respectively) but scores were significantly lower than when the programme was NHS-funded (92% n = 851/922 and 88% n = 813/922, respectively; P = 0.004). One person (2%) attended the weight loss programme, which is significantly lower than the 40% of participants who attended when the programme was NHS-funded (P<0.0001).ConclusionGP referral to a weight loss programme that requires patients to pay rather than offering an NHS-funded programme is acceptable; however, it results in almost no attendance.

Few health care professionals receive comprehensive training in how to effectively help their patients with obesity. Yet patients are often wanting, needing, and looking for help when they go to the doctor. We, as a group of patients with obesity, share our common experiences and needs when going to the doctor from a place of honesty and hope, with the assumption that clinicians want to know what their patients really think and feel. Our "wish list" for a treatment plan may represent an ideal, but our hope is that our language will speak to clinicians about how they can help their patients manage their obesity.

This study was an analysis of a national sample of U.S. medical office visits from 2014 to 2016, a period when evidence of effectiveness was emerging for a variety of beneficial type 2 diabetes agents with regard to potential reduction in diabetes comorbidities. Ideal therapy was defined as an American Diabetes Association–identified beneficial agent plus metformin. The associations between atherosclerotic cardiovascular disease or obesity and use of these agents were explored.

Scientists set out to investigate a potential role of the gut microbiota in the development of cardio-metabolic diseases. They ended up identifying the common cholesterol-lowering drug statins as a potential microbiota-modulating therapeutic.

Green tea supplementation is associated with a decrease in body weight and body mass index in obese patients, according to a new systematic review and meta-analysis of randomized controlled trials. “Green tea is one of the major types of tea (Camelia sinensis) and belongs to the non-fermented tea class,” said corresponding author Dr. Jing Wei [...]

Obese mice with unhealthy lifestyles gain significantly less weight and avoid type 2 diabetes when they receive bacteriophages from the faeces of a lean mouse, according to a new University of Copenhagen study.
