Adolescent bariatric surgery program characteristics: the Teen Longitudinal Assessment of Bariatric Surgery (Teen-LABS) study experience

Adolescent Bariatric Surgery: The Need for Tailored Educational Materials

Rates of class III, or greater, obesity have risen among adolescents in the United States. Metabolic and bariatric surgery (MBS) is a safe and effective treatment option for severe obesity among teenagers that results in improvements in cardiometabolic and psychosocial health. Despite its effectiveness, MBS remains largely underutilized and misconceptions exist among providers, parents/guardians, and adolescents. In addition, adolescents who have undergone MBS procedures report there are some topics they wish they had known more about before surgery and express concern that their unique needs are not understood. One potential solution to address these concerns includes preoperative educational materials tailored for adolescents. Currently, there are no standardized recommendations for preoperative educational materials. This editorial suggests the use of community-engaged research, and qualitative methodology, to consult with the primary stakeholder groups of preoperative adolescents, postoperative adolescents, parents/guardians, and clinicians to develop tailored materials that address the unique needs of adolescents undergoing surgical treatment for obesity.

Assessment of electronic patient education materials for adolescent bariatric surgery candidates: An environment scan

Objective

Adolescents who opt for metabolic and bariatric surgery (MBS) will use the internet to learn about the procedure. The objective of this study is to assess the suitability of electronic patient education materials (ePEM) of North American centers that perform adolescent bariatric surgery.

Methods

Canadian and American bariatric centers that perform adolescent MBS were identified from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program and Google web-based searches. Suitability of ePEM for the adolescent readership was evaluated using the Suitability Assessment of Materials (SAM).

Results

Sixty-five centers were evaluated from June to July 2020 with 41% citing adolescent specific material. Six percent of the ePEM were evaluated as 'not suitable', 69% were evaluated as 'adequate', and 25% were evaluated as 'superior'.

Conclusion

Adequate ePEM scoring was obtained, but centers had little resources tailored to adolescent patients. Further research is needed to evaluate all the resources provided to adolescents (i.e., resources provided by the health team) to ensure the tools are appropriate for the adolescent readership.

Innovation

This environmental scan provided insights to ePEM available for adolescents considering MBS.

Bariatric surgery practice patterns among pediatric surgeons in the United States

BACKGROUND

Metabolic and bariatric surgery (MBS) in adolescents has been shown to be safe and effective, but current practice patterns are variable and poorly understood. The aim of this study is to assess current MBS practice patterns among pediatric surgeons in the United States.

METHODS

American Pediatric Surgical Association members were surveyed on current bariatric surgery practices.

RESULTS

Four hundred and three (40%) surgeons out of a total of 1013 pediatric surgeons responded to the survey. Only 2 respondents had additional training in MBS (0.5%). One hundred thirty-two (32.6%) report that their practice participates in metabolic and bariatric surgery, with 123 (30.4%) having a specific partner specializing in MBS. Most respondents (92%) stated that they believe high volume is associated with better outcomes with regard to MBS. Only 17 (4.2%) surgeons performed a metabolic and bariatric surgery in the last year. All routinely perform sleeve gastrectomy as their primary procedure. Most (82%) perform procedures with an additional surgeon, either another pediatric surgeon (47%) or an adult bariatric surgeon (47%). All pediatric bariatric surgeons responded that they believe high volume led to better outcomes. Adolescent MBS programs most commonly included pediatric nutritionists (94%), pediatric psychologists (94%), clinical nurses (71%), clinical coordinators (59%), pediatric endocrinologists (59%), and exercise physiologists (52%).

CONCLUSION

Only 17 (4.2%) respondents had performed a metabolic and bariatric surgery in the past year, and few of those had additional training in MBS. Future work is necessary to better understand optimal practice patterns for adolescent metabolic and bariatric surgery.

Obesity in Children

Child obesity is widely prevalent, and general pediatricians play an important role in identifying and caring for patients with obesity. Appropriate evaluation and treatment require an understanding of the complex etiology of child obesity, its intergenerational transmission, and its epidemiologic trends, including racial/ethnic and socioeconomic disparities. The American Academy of Pediatrics has published screening, evaluation, and treatment guidelines based on the best available evidence. However, gaps in evidence remain, and implementation of evidence-based recommendations can be challenging. It is important to review optimal care in both the primary care and multidisciplinary weight management settings. This allows for timely evaluation and appropriate referrals, with the pediatrician playing a key role in advocating for patients at higher risk. There is also a role for larger-scale prevention and policy measures that would not only aid pediatricians in managing obesity but greatly benefit child health on a population scale.

Childhood Obesity: Position Statement of Polish Society of Pediatrics, Polish Society for Pediatric Obesity, Polish Society of Pediatric Endocrinology and Diabetes, the College of Family Physicians in Poland and Polish Association for Study on Obesity

Childhood obesity is one of the most important problems of public health. Searching was conducted by using PubMed/MEDLINE, Cochrane Library, Science Direct, MEDLINE, and EBSCO databases, from January 2022 to June 2022, for English language meta-analyses, systematic reviews, randomized clinical trials, and observational studies from all over the world. Five main topics were defined in a consensus join statement of the Polish Society of Pediatrics, Polish Society for Pediatric Obesity, Polish Society of Pediatric Endocrinology and Diabetes and Polish Association for the Study on Obesity: (1) definition, causes, consequences of obesity; (2) treatment of obesity; (3) obesity prevention; (4) the role of primary care in the prevention of obesity; (5) Recommendations for general practitioners, parents, teachers, and regional authorities. The statement outlines the role of diet, physical activity in the prevention and treatment of overweight and obesity, and gives appropriate recommendations for interventions by schools, parents, and primary health care. A multisite approach to weight control in children is recommended, taking into account the age, the severity of obesity, and the presence of obesity-related diseases. Combined interventions consisting of dietary modification, physical activity, behavioral therapy, and education are effective in improving metabolic and anthropometric indices. More actions are needed to strengthen the role of primary care in the effective prevention and treatment of obesity because a comprehensive, multi-component intervention appears to yield the best results.

Technical review: Vertical sleeve gastrectomy in adolescents

Sleeve gastrectomy is an effective tool for inducing sustainable weight loss in adolescents with obesity. It is a seemingly straight-forward procedure, and yet deceptive in technical nuances. This review highlights the technical preparation (equipment, patient positioning, pre-operative management), and conduct (anatomy, instruments, methodology, pitfalls) of the operation, and concludes with essentials for anticipating and managing complications of the operation. Throughout the discussion, we emphasize practical techniques to maintain patient safety while achieving maximum weight loss benefits.

Short- and long-term safety and efficacy of bariatric surgery for severely obese adolescents: a narrative review

The selection criteria, safety, and efficacy of bariatric surgery are well established in adults but are less well defined for severely obese adolescents. The number of severely obese adolescents who could benefit from weight loss surgery is increasing, although referral rates have plateaued. Surgical options for these adolescents are controversial and raise several questions. Recent studies, including the prospective Teen-Longitudinal Assessment of Bariatric Surgery Study and the Adolescent Morbid Obesity Surgery Study, help answer these questions. Early bariatric surgical intervention improves body mass index but, more importantly, improves cardiovascular and metabolic co-morbidities of severe obesity. A review of the medical, psychosocial, and economic risks and benefits of bariatric surgery in severely obese adolescents is a step toward improving the management of a challenging and increasing population. We describe the current knowledge of eligibility criteria, preoperative evaluation, surgical options, outcomes, and referral barriers of adolescents for bariatric surgery.

Metabolic and Bariatric Surgery for Pediatric Patients With Severe Obesity

Severe obesity affects the health and well-being of millions of children and adolescents in the United States and is widely considered to be an "epidemic within an epidemic" that poses a major public health crisis. Currently, few effective treatments for severe obesity exist. Metabolic and bariatric surgery are existing but underuse treatment options for pediatric patients with severe obesity. Roux-en-Y gastric bypass and vertical sleeve gastrectomy are the most commonly performed metabolic and bariatric procedures in the United States and have been shown to result in sustained short-, mid-, and long-term weight loss, with associated resolution of multiple obesity-related comorbid diseases. Substantial evidence supports the safety and effectiveness of surgical weight loss for children and adolescents, and robust best practice guidelines for these procedures exist.

Partnering Support Interventions with Bariatric Surgery to Maximize Health Outcomes in Adolescents with Severe Obesity

OBJECTIVE

Rates of adolescents with severe obesity continue to rise worldwide, with concurrent increases in metabolic and bariatric surgery (MBS) uptake. The gap between support (lifestyle, pharmacotherapy) interventions and MBS as treatment options for adolescents has been understudied. This review, couched in a socio-ecological framework, investigates how support interventions for adolescents with severe obesity could be combined or sequenced with MBS to optimize health outcomes.

METHODS

A comprehensive search revealed 36 published articles between 1995 and 2019 that included the combination of support interventions and MBS among adolescents.

RESULTS

There were no studies that specifically reported outcomes or effect sizes for the combination of lifestyle intervention with MBS. Previous studies have reported individual results for either lifestyle intervention or MBS but not for their compound effect.

CONCLUSIONS

As rates of adolescents with severe obesity are on the rise globally, future research should focus on how partnering support interventions with MBS can amplify positive short- and long-term health outcomes and within a socio-ecological framework. Understanding the sequence of these approaches will be of particular importance. High-risk and vulnerable populations such as ethnic minorities who have suffered a disproportionate burden of the obesity epidemic must be included in rigorously tested future trials of combination interventions to maximize health outcomes worldwide.

Change, predictors and correlates of weight- and health-related quality of life in adolescents 2-years following bariatric surgery

Background/Objectives:

Weight-related quality of life (WRQOL) and generic health-related quality of life (HRQOL) have been identified as important patient reported outcomes for obesity treatment and outcome research. This study evaluated patterns of WRQOL and HRQOL outcomes for adolescents at 24-months post-bariatric surgery relative to a non-surgical comparator sample of youth with severe obesity, and examined potential weight-based (e.g., BMI, weight dissatisfaction) and psychosocial predictors and correlates of these outcomes.

Subjects/Methods:

Multi-site data from 139 adolescents undergoing bariatric surgery (M_age=16.9; 79.9% female, 66.2% White; M_{Body Mass Index [BMI]=} 51.5kg/m²) and 83 comparators (M_age=16.1; 81.9 % female, 54.2% White; M_BMI= 46.9kg/m²) were collected at pre-surgery/baseline, 6-, 12-, and 24-months post-surgery/baseline with high participation rates across time points (>85%). Self-reports with standardized measures of WRQOL/HRQOL as well as predictors/covariates (e.g., weight dissatisfaction, social support, peer victimization, family dysfunction, loss of control eating, self-worth, and internalizing symptoms) were obtained. Growth curve models using structural equation modeling examined WRQOL/HRQOL over time and linear regressions examined predictors and correlates of WRQOL/HRQOL outcomes.

Results:

Significant improvement in WRQOL and Physical HRQOL, particularly in the first post-operative year with a leveling off subsequently, was found for the surgical group relative to comparators, but with no significant Mental HRQOL change. At 24 months, the surgical group had signficantly greater WRQOL/HRQOL across most subscales. Within the surgical group at 24 months, weight-based variables were signficantly associated with WRQOL and Physical HRQOL, but not Mental HRQOL. Mental HRQOL was associated with greater internalizing symptoms and loss of control eating.

Conclusions:

For adolescents undergoing bariatric surgery, most clinically meaningful changes in WRQOL and Physical HRQOL occurred early post-operatively, with weight-based variables as the primary drivers of 24-month levels. In contrast, expectations for Mental HRQOL improvement following surgery should be tempered, with 24-month levels significantly associated with psychosocial rather than weight-based correlates.

New treatment modalities for obesity

The treatment of childhood obesity represents a greater challenge for pediatricians. To date, it is multidisciplinary, including behavioral, dietary, pharmacological, and surgical options. Given the limited efficacy of available treatments, scientific research on finding new solutions is very active. Several drugs comprising Metformin, Glucagon-like peptide- 1 receptor agonists, Naltrexone-bupropion, Phentermine-Topiramate, and Lorcaserin have been studied as pediatric antiobesity agents. Findings from clinical trials showed a modest but significant effect of these drugs on weight loss, but long-term studies are needed to better define their exact role. Bariatric surgery is also promising for extremely obese adolescents. Moreover, a novel approach to treat obesity might be represented by compounds inducing browning of white adipose tissue, a complex process involved in body energy homeostasis, but at present evidence in humans is lacking. We aimed to review the current knowledge regarding the available new options for pediatric obesity treatment.

Laparoscopic sleeve gastrectomy in adolescents with or without syndromic obesity: two years follow-up

INTRODUCTION

Childhood obesity is an emerging health problem. Surgical treatment of obese adolescents, particularly those affected by congenital syndrome, represents a controversial issue. The aim of this multicenter study was to retrospectively assess the results of laparoscopic sleeve gastrectomy (LSG) in a cohort of adolescents affected by morbid obesity, with or without congenital syndromes.

MATERIALS AND METHODS

Forty-one obese (BMI 49 ± 6 kg/m²) adolescents with mean age of 16 ± 3 years (58.5% with previous intragastric balloon failure), and subjected to LSG, were retrospectively evaluated for complications rate, % excess weight loss (%EWL), and inhibition of co-morbidities after 2 years of follow-up.

RESULTS

All the operations were completed laparoscopically and no intra-operative complications were recorded. No mortality was recorded while peri- or post-operative complications only occurred in two patients (4.9%). The EWL% at 6, 12, and 24 months were 42.3, 58.3, and 59.4, respectively. %EWL was comparable (p = 0.7) between non-syndromic and syndromic obese adolescents at 24 months. Conversely patients with previous intragastric balloon surgery had a significant lower EWL (%) at 24 month (p < 0.01). Moreover, at the same time point, co-morbidity resolution rate was 78.2% while improvement rate was 57.6%. Specifically, remission rate of type 2 diabetes (T2DM), hypertension and obstructive sleep apnea (OSA) were 71, 75 and 61%, respectively.

CONCLUSION

LSG is advantageous in the treatment of morbidly obese juveniles concerning safety, weight loss and co-morbidity control and at same time presenting, a possible effective therapeutic option for patients affected by congenital syndrome.

ASMBS pediatric metabolic and bariatric surgery guidelines, 2018

The American Society for Metabolic and Bariatric Surgery Pediatric Committee updated their evidence-based guidelines published in 2012, performing a comprehensive literature search (2009-2017) with 1387 articles and other supporting evidence through February 2018. The significant increase in data supporting the use of metabolic and bariatric surgery (MBS) in adolescents since 2012 strengthens these guidelines from prior reports. Obesity is recognized as a disease; treatment of severe obesity requires a life-long multidisciplinary approach with combinations of lifestyle changes, nutrition, medications, and MBS. We recommend using modern definitions of severe obesity in children with the Centers for Disease Control and Prevention age- and sex-matched growth charts defining class II obesity as 120% of the 95th percentile and class III obesity as 140% of the 95th percentile. Adolescents with class II obesity and a co-morbidity (listed in the guidelines), or with class III obesity should be considered for MBS. Adolescents with cognitive disabilities, a history of mental illness or eating disorders that are treated, immature bone growth, or low Tanner stage should not be denied treatment. MBS is safe and effective in adolescents; given the higher risk of adult obesity that develops in childhood, MBS should not be withheld from adolescents when severe co-morbidities, such as depressed health-related quality of life score, type 2 diabetes, obstructive sleep apnea, and nonalcoholic steatohepatitis exist. Early intervention can reduce the risk of persistent obesity as well as end organ damage from long standing co-morbidities.

Infant-juvenile type 2 diabetes

In recent years, we have witnessed an increase in the number of cases of type 2 diabetes mellitus (DM2) in children and adolescents, which has paralleled the increase in the worldwide prevalence of obesity. Although screening the general population does not appear to be cost-effective, special attention should be paid to children with excess weight, obesity or other factors that predispose them to a state of insulin resistance. When faced with the diagnosis of childhood DM2, the presence of comorbidities (such as hypertension, dyslipidemia and microalbuminuria) should be assessed, and appropriate treatment and follow-up should be administered to prevent the onset of complications, given that the DM2 in this population group will last longer than that started in adulthood.

Changes in Dietary Intake and Eating Behavior in Adolescents After Bariatric Surgery: an Ancillary Study to the Teen-LABS Consortium

BACKGROUND

A growing number of studies suggest that bariatric surgery is safe and effective for adolescents with severe obesity. However, surprisingly little is known about changes in dietary intake and eating behavior of adolescents who undergo bariatric surgery.

OBJECTIVE

Investigate changes in dietary intake and eating behavior of adolescents with obesity who underwent bariatric surgery (n = 119) or lifestyle modification (LM) (n = 169).

SETTING

University-based health systems METHODS: A prospective investigation of 288 participants (219 female and 69 male) prior to bariatric surgery or LM and again 6, 12, and 24 months (surgery patients only) after treatment. Measures included changes in weight, macronutrient intake, eating behavior, and relevant demographic and physiological variables.

RESULTS

Adolescents who underwent bariatric surgery experienced significantly greater weight loss than those who received LM. The two groups differed in self-reported intake of a number of macronutrients at 6 and 12 months from baseline, but not total caloric intake. Patients treated with surgery, compared to those treated with LM, also reported significantly greater reductions in a number of disordered eating symptoms. After bariatric surgery, greater weight loss from postoperative month 6 to 12 was associated with self-reported weight consciousness, craving for sweets, and consumption of zinc.

CONCLUSIONS

Adolescents who underwent bariatric surgery, compared to those who received LM, reported significantly greater reductions in weight after 1 year. They also reported greater reductions in disordered eating symptoms. These findings provide new information on changes in dietary intake and eating behavior among adolescents who undergo bariatric surgery.

Accuracy of Self-Reported Weight Among Adolescent and Young Adults Following Bariatric Surgery

PURPOSE

This study evaluates accuracy of self-reported weight in adolescent bariatric surgery patients.

MATERIALS AND METHODS

During follow-up visits, participants self-reported weight and had weight measured. The differences between self-reported and measured weights were analyzed from 60 participants.

RESULTS

Participants were 70% (n = 42) female, 72% (n = 43) white, mean age of 20.8 years and a median body mass index of 36.6 kg/m². At an average of 3.5 years following surgery, females underestimated weight (0.5 kg, range: -18.7 to 5.6 kg), while males overestimated (1.1 kg, range: -7.8 to 15.2 kg). Most (80%, n = 48) reported within 5 kg of measured weight. The majority of adolescents who previously underwent bariatric surgery reported reasonably accurate weights, but direction of misreporting varied by gender.

CONCLUSION

Self-reported weights could be utilized when measured values are unavailable without markedly biasing the interpretation of outcomes.

Peer Victimization in Adolescents With Severe Obesity: The Roles of Self-Worth and Social Support in Associations With Psychosocial Adjustment

Objective

To examine the associations of peer victimization with internalizing symptoms, externalizing symptoms, social competence, and academic performance in a clinical sample of adolescents with severe obesity, and whether self-worth and social support affect these associations.

Methods

Multisite cross-sectional data from 139 adolescents before weight loss surgery ( M age = 16.9; 79.9% female, 66.2% White; M Body Mass Index [BMI] = 51.5 kg/m 2 ) and 83 nonsurgical comparisons ( M age = 16.1; 81.9% female, 54.2% White; M BMI = 46.9 kg/m 2 ) were collected using self-reports with standardized measures.

Results

As a group, participants did not report high levels of victimization. Self-worth mediated the effects of victimization on a majority of measures of adjustment, and further analyses provided evidence of the buffering effect of social support for some mediational models.

Conclusions

Self-worth and social support are important targets for prevention and intervention for both victimization and poor adjustment in adolescent severe obesity.

Adolescents' decision to pursue bariatric surgery: a systematic review protocol

REVIEW QUESTION/OBJECTIVE

The objective of this qualitative review is to identify what motivates an adolescent to pursue bariatric surgery.

A multidisciplinary approach to laparoscopic sleeve gastrectomy among multiethnic adolescents in the United States

BACKGROUND

Childhood obesity has become a serious public health problem in our country with a prevalence that is disproportionately higher among minority groups. Laparoscopic sleeve gastrectomy (LSG) is gaining attention as a safe bariatric alternative for severely obese adolescents.

STUDY DESIGN

A retrospective study on morbidly obese adolescents that underwent LSG at our institution from 2009 to 2017. Primary outcomes were weight loss as measured by change in BMI and percent excess weight loss (%EWL) at 1 year after surgery, resolution of comorbidities and occurrence of complications.

RESULTS

Thirty-eight patients, of whom 71% were female and 74% were ethnic minorities, underwent LSG between 2009 and 2016. Mean age was 16.8years, mean weight was 132.0kg and mean BMI was 46.7. There were no surgical complications. Mean %EWL was 19.4%, 27.9%, 37.4%, 44.9%, and 47.7% at 1.5, 3, 6, 9, and 12month follow up visits, respectively. Comorbidity resolution rates were 100% for hypertension and nonalcoholic fatty liver disease, 91% for diabetes, 44% for prediabetes, 82% for dyslipidemia and 89% for OSA.

CONCLUSIONS

LSG is an effective and safe method of treatment of morbid obesity in adolescents as it can significantly decrease excess body weight and resolve comorbid conditions. Further studies are needed to investigate the long-term effects of LSG in adolescents.

Evidence Base for Multidisciplinary Care of Pediatric/Adolescent Bariatric Surgery Patients

PURPOSE OF REVIEW

Severe childhood obesity, defined as having a body mass index (BMI) greater than the 99th percentile for age and gender, is rising in most countries and is associated with early morbidity and mortality. Optimal management of the health of the child with obesity requires a multidisciplinary approach that identifies and treats associated derangements.

RECENT FINDINGS

Lifestyle interventions such as diet, exercise, and behavioral therapy for the severely obese pediatric patient are generally not effective. Few centers worldwide offer bariatric surgery for adolescents in a multidisciplinary setting, and we are the only center that offers a multidisciplinary approach that incorporates bariatric surgery for severely obese children and adolescents across all age groups. In this paper, we review up-to-date evidence in this subject including ours, and provide details on the multidisciplinary approach to pediatric obesity that accommodates bariatric surgery for children across all age groups.

Family factors that characterize adolescents with severe obesity and their role in weight loss surgery outcomes

OBJECTIVE

To comprehensively assess family characteristics of adolescents with severe obesity and whether family factors impact weight loss outcomes following weight loss surgery (WLS).

METHODS

Multisite prospective data from 138 adolescents undergoing WLS and primary caregivers (adolescent: M_age  = 16.9; M_BMI = 51.5 kg/m² ; caregiver: M_age  = 44.5; 93% female) and 83 nonsurgical comparators (NSComp: adolescent: M_age  = 16.1; M_{BMI =} 46.9 kg/m² ; caregiver: M_age  = 43.9; 94% female) were collected using standardized measures at presurgery/baseline and at 1 and 2 years.

RESULTS

The majority (77.3%) of caregivers had obesity, with rates of caregiver WLS significantly higher in the WLS (23.8%) versus NSComp group (3.7%, P < 0.001). Family dysfunction was prevalent (≈1 in every two to three families), with rates higher for NSComp than the WLS group. For the WLS group, preoperative family factors (i.e., caregiver BMI or WLS history, dysfunction, social support) were not significant predictors of adolescent weight loss at 1 and 2 years postoperatively, although change in family functioning over time emerged as a significant correlate of percent weight loss.

CONCLUSIONS

Rates of severe obesity in caregivers as well as family dysfunction were clinically noteworthy, although not related to adolescent weight loss success following WLS. However, change in family communication and emotional climate over time emerged as potential targets to optimize weight loss outcomes.

Psychological contributors to noncompletion of an adolescent preoperative bariatric surgery program

BACKGROUND

Noncompletion of preoperative bariatric programs is a significant problem among adolescents. Adult studies suggest that psychological factors contribute to noncompletion of preoperative bariatric programs.

OBJECTIVE

The aim of this study was to determine the association between adolescent psychological functioning and completion of the preoperative phase of a bariatric program.

SETTING

The study was conducted at a tertiary care children's hospital affiliated with a university medical center.

METHODS

Seventy-four adolescents and their parents completed an assessment measure of psychological functioning with the Behavior Assessment System for Children, Second Edition. We compared these scores between adolescents who completed the preoperative phase of the bariatric program and proceeded to surgery (completers) to those who did not (noncompleters) using multivariate analysis of covariance and logistic regression analyses, adjusting for demographic characteristics and baseline body mass index.

RESULTS

The mean age was 16.0 (1.1) years, most were female (79.8%), and the group was diverse (48.6%, Caucasian; 33.8%, black; 17.6%, other, including Hispanic, Asian, and biracial). Average body mass index was 50.5 (7.6) kg/m². Forty-two percent of participants were noncompleters. Noncompleters were reported by parents to have more clinically significant externalizing and internalizing behaviors and fewer adaptive behaviors. Noncompleters self-reported more clinically significant internalizing symptoms, emotional problems, and poor personal adjustment.

CONCLUSION

Adolescents who did not complete the preoperative phase of a bariatric surgery program had more clinically significant psychological symptoms across multiple domains compared with those who successfully proceeded to bariatric surgery. Early identification and treatment of psychological symptoms may be important in helping adolescents successfully proceed to surgery.

Early improvement in obstructive sleep apnea and increase in orexin levels after bariatric surgery in adolescents and young adults

BACKGROUND

Obstructive sleep apnea (OSA) associated with obesity is known to improve after bariatric surgery, but little is known about early changes in this condition after surgery.

OBJECTIVES

To study the clinical course of OSA after bariatric surgery SETTING: Children's hospital in the United States METHODS: Adolescents and young adults with obstructive sleep apnea undergoing vertical sleeve gastrectomy (n = 6) or gastric bypass (n = 1) were enrolled in this prospective study. Participants underwent formal polysomnography before and at 3 and 5 weeks after bariatric surgery. Anthropometric measurements and assay for orexin and leptin were also performed at study visits. Thirty-one adolescents who underwent 2 polysomnography studies that were 4 weeks apart served as control patients.

RESULTS

Baseline mean (range) age of participants was 17.8 (15.4-20.7) years, 71% were male, with body mass index of 55.2 (41.3-61.6) kg/m² and had a median apnea hypopnea index (AHI) of 15.8 (7.1-23.8) events/hour. Differences in least-square means from longitudinal analysis did not show significant differences in AHI in the control group but showed significant postoperative decline in AHI relative to baseline. AHI declined postoperatively from baseline by 9.2 events/hour (95% confidence interval: 3.8 to 14.5) at 3 weeks (P = .002) and 9.1 events/hour (95% confidence interval: 3.8 to 14.5) at 5 weeks (P = .002); there was no significant change from 3 to 5 weeks in AHI. Leptin decreased and orexin levels increased significantly by 3 weeks postoperatively.

CONCLUSIONS

These observations suggest that OSA responds early and out of proportion to weight loss after metabolic and or bariatric surgery, thus weight independent factors may at least in part be responsible for early improvement in OSA postoperatively.

Managing adolescent obesity and the role of bariatric surgery

PURPOSE OF REVIEW

This update explores the current management options for adolescent obesity with a specific focus on bariatric surgery.

RECENT FINDINGS

Research has highlighted the serious health complications associated with adolescent obesity and thus emphasized the need for effective interventions. With the increasing severity of obesity seen in younger populations, coupled with the modest effects of most behavioral and even pharmacologic interventions, there has been increased interest in, and attention on, bariatric surgery in younger populations. Recent adult-focused guidelines regarding the perioperative nutritional, metabolic, and nonsurgical support of the bariatric surgery patient outline the importance of careful patient selection, in addition to close monitoring, with a particular focus on preventing nutritional deficiencies. Several recent publications have focused on issues specific to bariatric surgery in the adolescent patient including the relationship between a patient's physical and emotional maturity and timing of surgery.

SUMMARY

Adolescent obesity is prevalent with increasing severity and long-term health implications. To date nonsurgical interventions have had modest effects. Bariatric surgery is becoming more common and has been shown to be well tolerated and effective in adolescents, but requires careful preoperative screening and postoperative monitoring.

Child Maltreatment and the Adolescent Patient With Severe Obesity: Implications for Clinical Care

OBJECTIVE

To characterize prevalence and correlates of child maltreatment (CM) in a clinical sample of adolescents with severe obesity.

METHOD

Multicenter baseline data from 139 adolescents undergoing weight loss surgery (Mage = 16.9; 79.9% female, 66.2% White; Mbody mass index [BMI] = 51.5 kg/m(2)) and 83 nonsurgical comparisons (Mage = 16.1; 81.9% female, 54.2% White; MBMI = 46.9 kg/m(2)) documented self-reported CM (Childhood Trauma Questionnaire) and associations with psychopathology, quality of life, self-esteem and body image, high-risk behaviors, and family dysfunction. 

RESULTS

CM prevalence (females: 29%; males: 12%) was similar to national adolescent base rates. Emotional abuse was most prevalent. One in 10 females reported sexual abuse. For females, CM rates were higher in comparisons, yet correlates were similar for both cohorts: greater psychopathology, substance use, and family dysfunction, and lower quality of life.

CONCLUSION

While a minority of adolescents with severe obesity reported a CM history, they carry greater psychosocial burden into the clinical setting.

Adolescent bariatric surgery: review on nutrition considerations

The prevalence of obesity in adolescents has dramatically increased over the past 3 decades in the United States. Weight loss surgery is becoming a viable treatment option for obese adolescents. The number of surgeries being performed yearly is rising, and this trend is likely to continue. Adolescent patients present a unique challenge to clinicians. There are currently best-practice recommendations and evidence-based nutrition guidelines for the treatment of the adolescent bariatric patient. A review of the current literature was performed to discuss bariatric surgery and nutrition for the adolescent patient. Studies show that most adolescents with obesity will become obese adults, thus increasing their risk of developing serious and debilitating health conditions. It is recommended that the candidates for surgery be referred to a practice that has a multidisciplinary team experienced in meeting the distinct physical and psychological needs of adolescents. Specific nutrition concerns for the adolescent bariatric patient include preoperative educational pathway, postoperative dietary progression, female reproduction, compliance with vitamin/supplementation recommendations, laboratory tests, and long-term monitoring. The medical literature has reported positive outcomes of bariatric surgery in adolescents with severe obesity. Before surgery is offered as an option, unique factors to adolescents must be addressed. The multidisciplinary clinical team must consider the adolescents' cognitive, social, and emotional development when considering their candidacy for surgery. As the number of adolescent bariatric surgery programs increases, continued research and long-term outcome data need to be collected and shared to base future treatment decisions.
