Psychosocial status and mental health in adolescents before and after bariatric surgery: a systematic literature review

Associations between Adolescent Preoperative Mental Health, Psychosocial Factors, and Body Mass Index

BACKGROUND

There is little research on adolescent bariatric surgery and mental health (depression, anxiety, etc.) with racial/ethnic minority adolescents. The objective of this study is to determine associations between adolescents' preoperative reports of depression, anxiety, and self-esteem and caregiver's' reports of the caregiver-adolescent relationship and interpersonal relationships with adolescents' BMI and differences based on race/ethnicity.

METHOD

Adolescents (ages 12-21) who underwent metabolic and bariatric surgery from June 2020 to November 2022 had their responses to specific items on the BASC-3 (anxiety, depression, and self-esteem) analyzed for associations with their body mass index (BMI) and with caregiver responses to the BASC-3 for adolescents' interpersonal skills and relationship with caregiver. Demographic differences on the BASC-3 were assessed. Pearson's correlations, independent t-tests, and ANOVA were used.

RESULTS

Caregivers who had higher t-scores for relationship with their adolescents had adolescents who had lower depression t-scores, lower anxiety t-scores, and higher self-esteem t-scores. Parents who had higher t-scores for their adolescents' interpersonal relations had adolescents who had lower depression t-scores, lower anxiety t-scores, and higher self-esteem t-scores. White adolescents had higher depression t-scores than Black and Hispanic adolescents. Black and Hispanic adolescents had higher self-esteem t-scores compared to White adolescents.

DISCUSSION

Some of the findings within the study regarding adolescents' race and ethnicity and mental health are not consistent with prior research, affirming the need for additional research of these sub-populations.

Quality of Life in Patients Undergoing Revisional Bariatric Surgery: From Sleeve Gastrectomy to Roux-en-Y Gastric Bypass

Sleeve gastrectomy (SG) is the most performed bariatric surgery worldwide. However, this surgery may be associated with long-term weight regain and severe gastroesophageal reflux disease (GERD), sometimes necessitating conversion to Roux-en-Y gastric bypass (RYGB) to improve quality of life (QoL). We conducted a systematic review on QoL measures following the conversion of SG to RYGB. We searched various databases for studies conducted between January 2005 and September 2023. Four studies, involving 196 participants in total, met the inclusion criteria. Different assessment methods were used to evaluate QoL following the conversion. In the included studies, we observed that GERD symptoms and proton pump inhibitor (PPI) use both decreased following conversion to RYGB. Excess weight loss (EWL) was also observed in all studies.

Mental health from 5 years before to 10 years after bariatric surgery in adolescents with severe obesity: a Swedish nationwide cohort study with matched population controls

BACKGROUND

The long-term effects of bariatric surgery on the mental health of adolescents with severe obesity remain uncertain. We aimed to describe the prevalence of psychiatric health-care visits and filled prescription psychiatric drugs among adolescents with severe obesity undergoing bariatric surgery in the 5 years preceding surgery and throughout the first 10 years after surgery, and to draw comparisons with matched adolescents in the general population.

METHODS

Adolescents with severe obesity and who underwent bariatric surgery were identified through the Scandinavian Obesity Surgery Registry. We included adolescents who had bariatric surgery between 2007 and 2017 and were younger than 21 years at time of surgery. Each adolescent patient was matched with ten adolescents from the general population by age, sex, and county of residence. Specialist psychiatric care and filled psychiatric prescriptions were retrieved from nationwide data registers.

FINDINGS

1554 adolescents (<21 years) with severe obesity underwent bariatric surgery between 2007 and 2017, 1169 (75%) of whom were female. At time of surgery, the mean age was 19·0 years [SD 1·0], and the mean BMI was 43·7 kg/m2 (SD 5·5). 15 540 adolescents from the general population were matched with adolescents in the surgery group. 5 years before the matched index date, 95 (6·2%) of 1535 surgery patients and 370 (2·5%) of 14 643 matched adolescents had a psychiatric health-care visit (prevalence difference 3·7%; 95% CI 2·4-4·9), whereas 127 (9·8%) of 1295 surgery patients and 445 (3·6%) of 12 211 matched adolescents filled a psychiatric drug prescription (prevalence difference 6·2%; 95% CI 4·5-7·8). The year before the matched index date, 208 (13·4%) of 1551 surgery patients and 844 (5·5%) of 15 308 matched adolescents had a psychiatric health-care visit (prevalence difference 7·9%; 95% CI 6·2-9·6), whereas 319 (20·6%) of 1551 surgery patients and 1306 (8·5%) of 15 308 matched adolescents filled a psychiatric drug prescription (prevalence difference 12·0%; 10·0-14·1). The prevalence difference in psychiatric health-care visits peaked 9 years after the matched index date (12·0%; 95% CI 9·0-14·9), when 119 (17·6%) of 675 surgery patients and 377 (5·7%) of 6669 matched adolescents had a psychiatric health-care visit. The prevalence difference in filled psychiatric drug prescription was highest 10 years after the matched index date (20·4%; 15·9-24·9), when 171 (36·5%) of 469 surgery patients and 739 (16·0%) of 4607 matched adolescents filled a psychiatric drug prescription. The year before the matched index date, 19 (1·2%) of 1551 surgery patients and 155 (1·0%) of 15304 matched adolescents had a health-care visit associated with a substance use disorder diagnosis (mean difference 0·2%, 95% CI -0·4 to 0·8). 10 years after the matched index date, the prevalence difference had increased to 4·3% (95% CI 2·3-6·4), when 24 (5·1%) of 467 surgery patients and 37 (0·8%) of 4582 matched adolescents had a health-care visit associated with a substance use disorder diagnosis.

INTERPRETATION

Psychiatric diagnoses and psychiatric drug prescriptions were more common among adolescents with severe obesity who would later undergo bariatric surgery than among matched adolescents from the general population. Both groups showed an increase in prevalence in psychiatric diagnoses and psychiatric drug prescriptions leading up to the time of surgery, but the rate of increase in the prevalence was higher among adolescents with severe obesity than among matched adolescents. With the exception of health-care visits for substance use disorders, these prevalence trajectories continued in the 10 years of follow-up. Realistic expectations regarding mental health outcomes should be set preoperatively.

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.

Impact of Short-Term Weight Loss on Hemostasis and Thrombosis after Bariatric Surgery

Introduction

Obesity causes thrombophilia and many coagulation problems related to slowing the capillary flow. We aimed to evaluate rapid weight loss outcomes in the early period after bariatric surgery on the coagulation system. Materials and Method. A prospective study enrolled 28 patients with a BMI > 40 kg/m2 who underwent bariatric surgery. Preoperative and postoperative (first and third months) demographic criteria-such as age, gender, weight, height, and alcohol and tobacco use, and biochemical parameters such as PLT, PT, aPTT, INR, bleeding time, coagulation time, fibrinogen, D-dimer, albumin, calcium, ionized calcium, vitamin D, and PTH-were analyzed.

Results

We found that both bleeding and thrombotic parameters increase in early-slowing surgery. The first-month platelet levels were significantly different from the preoperative values (p < 0.001). The prothrombin time in the first (p < 0.001) and third months (p < 0.009) was also comparable. The PTT in the first month was higher than in the preoperative period (p < 0.011). INR in the first month (p < 0.001) was higher than that in the preoperative period and the third month (p = 0.007) value was higher than in the first month. In terms of fibrinogen levels, all parameters indicated statistical significance within each other; preoperative to the first month (p < 0.001), the first month to the third month (p < 0.016). Third-month D-dimer levels were lower than the first month's values (p = 0.032).

Conclusion

Thromboembolic events have crucial importance in the converse scenario of haemorrhagic diathesis during the first months of bariatric surgery. Vitamin support and antithrombotic agents may be recommended in the early postoperative period.

Long-term Outcomes Following Adolescent Metabolic and Bariatric Surgery

Severe obesity in adolescence negatively impacts upon health and wellbeing. Lifestyle modifications do not usually achieve a sufficient degree or durability of weight loss to mitigate the risk of medical complications. In recent years, metabolic and bariatric surgery (MBS), already a well-established treatment for adults with severe obesity, has emerged as an option in adolescents. Controlled studies in this age group have demonstrated substantial and sustained weight loss, improvements in associated health parameters, and a safety profile surpassing that observed in adult patients. This review aims to present published data on the results of MBS in adolescents with a focus on long-term outcomes. Indications for bariatric surgery and aspects of timing in the young person's life are also presented, along with safety considerations and factors influencing patient selection for surgery. We conclude, predominantly from short- to medium-term outcomes data, that MBS is a safe and valuable therapeutic option for adolescents with severe obesity. Considering the poor health and social wellbeing prognosis in this group, MBS appears to be underutilized. The need for continued research, multiprofessional specialist provision, coherent contemporary clinical guidelines, and routine long-term follow-up in adolescents undergoing MBS is highlighted.

Trajectories of Psychopathology and Dysregulation 2-4 Years following Adolescent Bariatric Surgery

OBJECTIVE

This study examined psychopathology and weight over 4 years following bariatric surgery in adolescents with obesity, as compared to a nonsurgical group. The role of psychological dysregulation in relation to psychopathology in the 2-4 year "maintenance phase" following surgery was also examined.

METHODS

Adolescent participants (122 surgical and 70 nonsurgical) completed height/weight and psychopathology assessments annually for 4 years, with dysregulation assessed at Year 2. Analyses examined the association of "High" and "Low" psychopathology with weight over time using logistic regression. Mediation analyses in the surgical group examined indirect effects of dysregulation on percent weight loss through Year 4 psychopathology.

RESULTS

There were lower odds of "High" internalizing symptoms in the surgical group versus the nonsurgical group from baseline (presurgery) to Year 4 (OR = .39; p < .001; 42.3% "High" internalizing in surgical; 66.7% in nonsurgical) and during the 2-4 year maintenance phase (OR = .35, p < .05; 35.1% "High" internalizing in surgical; 60.8% in nonsurgical). There was a significant mediation effect in the surgical group: higher dysregulation was associated with greater Year 4 internalizing symptoms (β = .41, p < .001) which in turn was associated with less Year 4 percent weight loss (β = -.27, p < .05).

CONCLUSIONS

While the surgical group was less likely to experience internalizing symptoms, internalizing psychopathology was related to less percent weight loss in this group. Internalizing symptoms mediated the relationship between dysregulation and percent weight loss in the surgical group. Postoperative mental health follow-up is needed for adolescents into young adulthood.

Ethics of Bariatric Surgery in Adolescence and Its Implications for Clinical Practice

Obesity is increasingly prevalent among adolescents. Clinical and research data support the use of bariatric surgery (BS) as a treatment option for severely obese adolescents, with good results in terms of weight loss, improvement or resolution of comorbidities, and compliance to follow up. Nevertheless, concerns still remain, with significant disparities among countries and ethical concerns mainly raised by performing an irreversible and invasive procedure in adolescence, with potential life-long alterations. In this context, the purpose of this narrative review was to discuss the main current ethical challenges in performing BS in adolescence and to inform appropriate clinical management in the field. The core ethical principles of autonomy, beneficence, nonmaleficence, and justice were revised in terms of patient-centered healthcare through the lens of psychosocial implications. The review concludes with a discussion regarding the potential directives for future research for effective, patient-centered, and ethical management of obesity in the adolescent population.

A visualized and scientometric analysis of research trends of weight loss in overweight/obese children and adolescents (1958-2021)

Background

Weight loss is an appropriate approach to reduce the health risks associated with overweight/obese children and adolescents, and the optimal method of weight loss requires further research. This study systematically explores scientific co-operation, disciplinary interaction, hotspots and trends in the field of weight loss in overweight/obese children and adolescents (WLOCA), and provides references for further research.

Methods

Citespace 5.8.R1 (64-bit) was adopted to conduct a comprehensive visualization analysis of the literature on WLOCA from Web of Science Core Collection, including publication, institution, country/region, author, journal, keywords and reference.

Results

2,513 papers were found in the Web of Science Core Collection, and the annual number of papers published has increased significantly since 2003. Cincinnati Children's Hospital is the institution with the largest number of publications, while Washington University plays a pivotal role in the collaboration network. In terms of nations, USA has made greater contributions than the rest in terms of the number of publications and global co-operation research. The most influential authors in this field are Thomas H. Inge, Thomas Reinehr, Todd M. Jenkins, Epstein LH, Ogden CL, etc. The most active journals are "Obesity," "International Journal of Obesity," "Obesity Surgery," "Pediatrics," etc. which are characterized by interdisciplinary interactions. Research hot topics mainly include "assessment of obesity and pathophysiological mechanism," "comprehensive intervention," and "bariatric surgery," and there's a gradual shift from "lifestyle intervention" and "pathophysiological mechanism" to "clinical surgical application." In addition, disciplinary integration and comprehensive research, targeted intervention and treatment, and prospective research are the future research trends.

Conclusion

The overall trend in WLOCA study is positive. The main contribution of this study is to reveal the overall picture of the research in this field with visual maps and detailed data by combining quantitative with qualitative approaches, which can provide valuable references for relevant researchers to quickly understand the status of studies on WLOCA, to seek co-operation, and grasp research hotspots and frontier trends.

Short-Term Changes in Mental, Physical, and Social Factors After Metabolic Bariatric Surgery in Adolescents: A Nationwide Prospective Cohort Study

Background

Metabolic bariatric surgery (MBS) is an effective treatment for adolescents with severe obesity. However, changes in mental, physical, and social factors, as well as their association with the extent of excess weight loss (%EWL) after MBS, remain controversial.

Methods

We followed 97 adolescents (64% females, aged 17 ± 0.9 years, BMI 46.1 ± 5.9 kg/m2) before and 9 months following MBS in a multi-center, prospective cohort study. Changes in mental, physical, and social factors were assessed by self-reported questionnaires, and associations with %EWL were evaluated after adjustment for potential confounders.

Results

The body mass index (BMI) decreased by 30%, and all physical parameters significantly improved (p ≤ 0.001). Energy level increased by 24%, mood level by 14%, and mental health by 9.5% (p ≤ 0.002). Social parameters were also improved, with a significant decrease in social rejection (p = 0.02), and an increase in participation in after-school social activities (p = 0.008). Mental health improvement was associated with baseline social rejection (r = 0.514, p < 0.001). The improvement in all factors was not related to the extent of %EWL.

Conclusion

Metabolic bariatric surgery MBS in adolescents led to a meaningful decrease in BMI and to an improvement in short-term physical, mental, and social factors that were not related to %EWL. Patients experiencing social rejection may improve their mental health following BS.

Obesity in children and adolescents: epidemiology, causes, assessment, and management

This Review describes current knowledge on the epidemiology and causes of child and adolescent obesity, considerations for assessment, and current management approaches. Before the COVID-19 pandemic, obesity prevalence in children and adolescents had plateaued in many high-income countries despite levels of severe obesity having increased. However, in low-income and middle-income countries, obesity prevalence had risen. During the pandemic, weight gain among children and adolescents has increased in several jurisdictions. Obesity is associated with cardiometabolic and psychosocial comorbidity as well as premature adult mortality. The development and perpetuation of obesity is largely explained by a bio-socioecological framework, whereby biological predisposition, socioeconomic, and environmental factors interact together to promote deposition and proliferation of adipose tissue. First-line treatment approaches include family-based behavioural obesity interventions addressing diet, physical activity, sedentary behaviours, and sleep quality, underpinned by behaviour change strategies. Evidence for intensive dietary approaches, pharmacotherapy, and metabolic and bariatric surgery as supplemental therapies are emerging; however, access to these therapies is scarce in most jurisdictions. Research is still needed to inform the personalisation of treatment approaches of obesity in children and adolescents and their translation to clinical practice.

Mental health of adolescents after bariatric surgery: A textual analysis

Mental health after bariatric surgery during adolescence has been little explored. This is a sensitive period in terms of self-image on which bariatric surgery could have negative effects because of the rapid and significant changes in morphology it induces. Previous studies have explored mental effects using questionnaires and only related to psychopathological disorders. The objective of our study was to complement these studies by exploring, via in-depth interviews, the adolescents' views on changes after bariatric surgery at psychological as well as socio-emotional levels. Fourteen adolescents with obesity were recruited in a French hospital 6-43 months after surgery. They participated in one-on-one interviews lasting an average of 45 minutes. A lexical analysis (using ALCESTE software^© ) of their speech highlighted the most positive effects, particularly in terms of social relationships, physical activities, self-esteem and reduced stigma, along with less positive effects in terms of eating behaviour and skin. In terms of clinical implications, this study confirmed the value of bariatric surgery for adolescents at psychological and social levels and its contribution to their mental health. However, it also highlighted the importance of pre- and post-operative support.

Contextualising Eating Disorder Concerns for Paediatric Obesity Treatment

PURPOSE OF REVIEW

Eating disorders are complex mental health conditions that share risk factors with obesity. This review outlines the context for concerns that paediatric obesity treatment presents a risk for eating disorder development.

RECENT FINDINGS

Most children and adolescents undergoing professionally supervised obesity treatment will have improvements or no change to eating disorder risk profiles. However, some may subsequently develop a clinical eating disorder, and this is proposed to relate to weight-focussed dietary interventions that are standard in paediatric obesity treatment. Nevertheless, dietary restraint may not be a strong predictor of eating disorder risk in the context of paediatric obesity treatment. Most international guidelines recommend weight maintenance or weight loss as a treatment goal, and weight loss is related to improvements in cardiometabolic health but not eating disorder risk in the short term. The risk of inducing or exacerbating an eating disorder during paediatric weight management is likely to be low; however, the serious consequences combined with increasing scale of obesity treatment, and lack of empirical evidence, are of concern. There is a need for further research to identify long-term predictors of eating disorder development for children and adolescents who seek treatment for their obesity.

Addressing psychosocial health in the treatment and care of adolescents with obesity

Obesity affects 158 million youth worldwide and is associated with psychosocial comorbidity. This review describes weight management options utilized by adolescents, including both self-directed weight loss and medically supervised obesity treatment interventions, and associated psychosocial impacts. A majority of adolescents with obesity attempt to manage weight on their own, primarily through attempting weight loss, sometimes with supplement use. Approaches such as these are associated with a degree of risk, disordered eating behaviors, and further weight gain. In contrast, medically supervised multicomponent interventions are associated with improved psychosocial health, including quality of life, self-esteem, and body image, and reduced symptoms of depression, anxiety, and eating disorders. Few studies utilizing antiobesity pharmacotherapy have reported psychosocial outcomes, and trials of bariatric surgery show some early improvements with a need for sustained psychological support following surgery. Greater access to medically supervised treatment services is required to facilitate obesity care for adolescents. Early data on psychosocial health and obesity treatment offer promising outcomes; however, larger randomized controlled trials and longer-term data are needed. Future research should include both physiological and psychosocial outcomes to assess impact of interventions on the holistic health of adolescents with obesity.

"Your own pace, your own path": perspectives of adolescents navigating life after bariatric surgery

INTRODUCTION

Bariatric surgery, an established weight-loss tool, may be offered to some adolescents with severe obesity. However, few studies explore adolescents' postoperative experiences beyond physical and metabolic outcomes and quality-of-life measures.

METHODS

Between 2016 and 2021, 45 semi-structured interviews were conducted with adolescents (16-20 years) at 6 months (N = 15), 12 months (N = 15), and 24 months (N = 15) following bariatric surgery. A deductive thematic analysis framework was applied by two independent coders (Cronbach's α = 0.84). Themes were identified and refined iteratively, and discrepancies were resolved through discussion.

RESULTS

Five major themes emerged related to: (1) weight-loss expectations vs. reality, (2) social landscape, (3) body image, (4) eating and moving, and (5) challenges for long-term success. The pace of and satisfaction with weight loss and side effects was heterogenous among participants, with most changes occurring early and stabilizing by 24 months. Adolescents adapted over time to their new social landscapes (e.g., relationships) and reported improved body image and confidence, yet persistently struggled to reconcile their internal identity with evolving external perceptions and discomfort with new attention. Participants experienced changes to lifestyle routines after surgery (e.g., eating, moving, habits), which introduced distress at 6 months but resolved over time. Life transitions in early adulthood (e.g., moving away, university/college, employment), concurrent with their evolving and increasing autonomy, physical, social, and financial independence, imposed unexpected challenges to postoperative routines and support systems. Participants unanimously reaffirmed that bariatric surgery is a lifelong journey and that they were committed to long-term success.

CONCLUSION

Our findings provide insight into optimizing adolescent selection for bariatric surgery and perioperative support. Specifically, important life transitions during this developmental period impact postoperative experiences and outcomes and adolescents may benefit from postoperative counseling focused on managing weight-loss expectations and adapting to evolving nutritional needs and changing social circumstances.

Metabolic and Bariatric Surgery in Adolescents

PURPOSE OF REVIEW

The prevalence of obesity is increasing in all age groups. Following its success in adults, and with limited success using conservative therapies, metabolic and bariatric surgery (MBS) is increasingly being utilized in adolescents. This review highlights the current evidence and guidelines supporting its use.

RECENT FINDINGS

Safety and efficacy mirror results seen in adults. The most recent evidence, as outcomes enter the long term, suggests that comorbidity resolution, including diabetes and hypertension, can even outperform that of adults. Mental health problems persist despite good weight loss. Overall, the positive early weight and comorbidity outcomes are well sustained into the long term. There is a growing need to prevent and treat adolescent obesity. Current evidence supports the use of MBS in adolescents. Ongoing and future studies will provide 10-year outcomes and assist in the refinement of multimodal pathways incorporating MBS for the treatment of severe childhood obesity.

Psychopathology and Adolescent Bariatric Surgery: A Topical Review to Support Psychologists in Assessment and Treatment Considerations

The rising rates of severe obesity among adolescents in the United States indicate a dire need for more intensive weight management strategies. While current evidence suggests that bariatric surgery is a safe and efficacious intervention for adolescents, the linkages with psychopathology before and after surgery are not well understood. Psychologists are an integral part of the interdisciplinary surgery team and play an important role in preparing youth for bariatric surgery as well as supporting adolescents post-surgery. The present manuscript reviews the literature on psychopathology in the context of adolescent bariatric surgery, discusses consideration of psychopathology as a contraindication for surgery, and provides recommendations on how psychologist members of the bariatric surgery team may balance attention to motivation and adherence to medical recommendations with assessment and treatment of psychopathology. Finally, the importance of continued research to confirm clinical consensus regarding decision-making and expansion of psychological resources within adolescent bariatric surgery programs are discussed.

Female adolescents with overweight and obesity share their perspectives on the clinical setting and weight management

The clinical setting remains a strategic environment for early assessment, identification and treatment of adolescents with obesity. Yet, healthcare providers' (HCPs) efforts have been unsuccessful in improving physical activity, nutritional intake or body mass index in adolescents with obesity. Obesity is a chronic condition that influences how patients interact with HCPs and experience ambulatory healthcare appointments. However, it is unknown how female adolescents with obesity perceive the clinical setting, especially regarding weight management. The purpose of this study was to explore the perceptions of female adolescents with obesity regarding health and weight management in the clinical setting. Using a qualitative design, 28 English-speaking female adolescents, 13 to 19 years of age, with a body mass index ≥85th percentile for height and weight participated in individual interviews. Results demonstrate that adolescents with obesity desire to be recognized as unique individuals and to be involved in their own health conversations. The participants reported that their health care was inadequate when they received impersonal and vague advice from HCPs on weight loss. Weight-related communication was best received in a kind and empathetic manner, with a focus on improving one's health (instead of losing weight). Adolescents in this study articulated the components of healthy eating and physical exercise, yet were unable to synthesize this knowledge into specific dietary practices and daily physical activities. The insights derived from female adolescents with obesity provide guidance on how HCPs can improve their relationship and engage the adolescent in weight-based discussions. Concrete, actionable recommendations are provided for providers who work with female adolescents who are overweight or obese.

Depressive and anxiety symptoms and suicidality in adolescent and young adult females with moderate to severe obesity before and after weight loss surgery

Data are conflicting regarding the impact of weight loss on mood and anxiety in adolescent and young adult females with moderate to severe obesity (OB), who are at increased risk for mood dysfunction compared with normal-weight females (NW). We examined depressive and anxiety symptoms in 94 females 13-21 years old: 39 in the NW group (body mass index [BMI]: 5th -85th percentiles) and 55 in the OB group (BMI >40 kg/m2 or >35 kg/m2 with comorbidities). Fifteen participants in the OB group who underwent bariatric surgery (gastric bypass or sleeve gastrectomy) and 15 getting routine care were re-assessed after 6 months. The Beck Depression Inventory-II (BDI-II) and State-Trait Anxiety Inventory (STAI) assessed depressive and anxiety symptoms, respectively. The OB group had higher BDI-II and STAI T-scores (P < .0001), a higher prevalence of clinical depression and anxiety (P < .001), and reported greater suicidal ideation (P = .02) vs the NW group. The bariatric surgery and non-surgical groups did not differ for changes in BDI-II and STAI T-Scores and suicidality over 6-month follow-up, despite greater weight loss in the former. Depressive and anxiety symptoms and suicidality were more frequently observed in the OB vs NW group. These symptoms did not improve following bariatric surgery despite significant weight loss, underscoring the need to investigate determinants of emergence and resolution of these symptoms in the OB group.

Implications of Perioperative Polypharmacy in Adolescents Undergoing Bariatric Surgery: a Single-Center Experience

Adolescents seeking bariatric surgery may present with pre-existing psychiatric diagnoses for which they use chronic medications. To heighten awareness concerning perioperative polypharmacy in adolescents with extreme obesity, we conducted a retrospective review of patients undergoing laparoscopic sleeve gastrectomy between February 2010 and May 2017 at Children's National Health System (CNHS). A total of 167 adolescent patients had pre-existing psychiatric diagnoses which included depression (50%), anxiety (23%), ADHD (23%), and binge eating disorder (11%). Medications prescribed to treat these diagnoses included selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). Additionally, all patients were given fentanyl, ondansetron, morphine, and acetaminophen perioperatively. Although no life threatening symptoms of drug-drug interactions (DDIs) were appreciated, the combined use of many different potent drugs in these patients warrants attention.

A review of the short- and long-term impact of weight loss on appetite in youth: what do we know and where to from here?

This review seeks to synthesise our knowledge about changes in hunger and satiety that occur during diet-induced weight loss and during weight loss maintenance, with a particular focus on youth with obesity. Mechanisms of appetite responses to weight loss rely heavily on the adult literature. Physiological mechanisms that control appetite and satiety via the gut-brain axis have been elucidated but we have an incomplete picture of changes in gut hormones and peptides in youth with obesity. In adolescents, the role of the brain in long-term sensing of body composition and modifying appetite and satiety changes is easily over-ridden by hedonic influences for the reward of highly palatable sweet foods and encourages over-consumption. Accordingly, reward cues and hyper-responsiveness to palatable foods lead to a pattern of food choices. Different reward systems are necessary that are substantial enough to reward the continued individual effort required to sustain new behaviours, that need to be adopted to support a reduced body weight. Periods of growth and development during childhood provide windows of opportunity for interventions to influence body weight trajectory but long-term studies are lacking. More emphasis needs to be placed on anticipatory guidance on how to manage powerful hedonic influences of food choice, essential to cope with living in our obesogenic environment and managing hunger which comes with the stronger desire to eat after weight has been lost.

Psychosocial Outcomes Following Adolescent Metabolic and Bariatric Surgery: a Systematic Review and Meta-Analysis

BACKGROUND

Metabolic and bariatric surgery is an effective strategy to curb the natural history of obesity progression and improve psychosocial status in the short term for adolescents with severe obesity. The medium- and long-term psychosocial impact of bariatric surgery in this population is not established.

METHODS

We searched MEDLINE (Ovid), EMBASE, Web of Science, PsycInfo, and the Cochrane Libraries through October 2017 for reports of weight loss surgery (roux-en-Y gastric bypass, sleeve gastrectomy, and adjustable gastric banding) on adolescents with severe obesity (age ≤ 21 years) having ≥ 6 months of follow-up. The primary outcome for inclusion in systematic review was use of a validated quality of life (QoL) or other psychosocial instrument at baseline and postoperatively. We used standardized mean difference (SMD) and random-effects modeling to provide summary estimates across different instruments.

RESULTS

We reviewed 5155 studies, of which 20 studies met inclusion criteria for qualitative synthesis. There were 14 studies and 9 unique cohorts encompassing 573 patients which were eligible for meta-analysis regarding postoperative change in QoL. Across surgical procedures, there was significant improvement in QoL of 1.40 SMD (95% confidence interval 0.95 to 1.86; I² = 89%; p < 0.001) at last follow-up (range 9-94 months). Trends in QoL improvement demonstrated the greatest improvement at 12 months; however, significant improvement was sustained at longest follow-up of 60+ months.

CONCLUSIONS

Weight loss surgery is associated with sustained improvement in QoL for adolescents with severe obesity across surgical procedures. Long-term data for psychosocial outcomes reflecting other mental health domains is lacking.

Mental health, loss of control eating, and cognitive functioning in adolescents undergoing bariatric surgery

Bariatric surgery is an effective treatment for severe obesity in adolescence. Nevertheless, much remains to be understood regarding the impact of surgery on mental health, eating behaviors, and cognition. We review the findings related to mental health both before and after surgery as well as long-term changes in psychopathology, including suicide risk. Overall, adolescents with and without a history of psychopathology lose weight at similar rates. At the same time, there is an increased risk for suicide that requires further study. Regarding alcohol and substance use, this population reports lower rates of consumption than age related non-obese cohorts. Nevertheless the impact of altered anatomy and metabolism on alcohol ingestion in a population at risk for substance use is concerning. Eating behaviors, specifically loss of control eating, are discussed. Finally, we include discussion of the cognitive changes occurring perioperatively and considerations for adolescents with cognitive impairments. Clinical recommendations and suggestions for future research are discussed.

Measuring quality of life in bariatric surgery: a multicentre study

BACKGROUND

Current studies mainly focus on total weight loss and comorbidity reduction. Only a few studies compare Quality of Life (QoL) after sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB). This study was conducted to examine the extent of improvement in QoL on different domains after primary bariatric surgery and compare these results to Dutch reference values.

METHODS

The study included prospectively collected data from patients who underwent primary bariatric surgery in five Dutch hospitals. The RAND-36 questionnaire was used to measure the patient's QoL; preoperatively and twelve months postoperatively. Postoperative scores were compared to Dutch reference values, standardized for age, using t-test. A difference of more than 5% was considered a minimal important difference. A multivariate linear regression analysis was used to compare SG and RYGB on the extent of improvement, adjusted for case-mix factors.

RESULTS

In total, 4864 patients completed both the pre- and postoperative questionnaire. Compared with Dutch reference values, patients postoperatively reported clinically relevant better physical functioning (RYGB + 6.8%), physical role limitations (SG + 5.6%; RYGB + 6.2%) and health change (SG + 77.1%; RYGB + 80.0%), but worse general health perception (SG - 22.8%; RYGB - 17.0%). Improvement in QoL was similar between SG and RYGB, except for physical functioning (β 2.758; p-value 0.008) and general health perception (β 2.607; p-value < 0.001) for which RYGB patients improved more.

CONCLUSIONS

SG and RYGB patients achieved a better postoperative score in physical functioning, physical role limitations and health change compared to Dutch reference values, and a worse score in general health perception.

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.

Early weight loss in adolescents following bariatric surgery predicts weight loss at 12 and 24 months

BACKGROUND

Growing evidence supports the efficacy of paediatric bariatric surgery. However, there is a paucity of data examining adolescent outcomes post surgery. Among adults, studies have shown that early weight loss is associated with long-term weight loss. Therefore, the aim of our study was to investigate the association between early weight loss at 3 months with longer-term weight loss at 12 and 24 months in adolescents post surgery. We hypothesized that patients who have greater weight loss within the first 3 months will have greater weight loss at 12 and 24 months post surgery.

METHODS

A retrospective chart review of bariatric surgery patients (n = 28) was conducted. Anthropometric measurements at baseline and 3, 12, and 24 months were analysed.

RESULTS

Percent of excess weight loss (%EWL) at 3, 12, and 24 months were 33.6 ± 11.3%, 55.0 ± 20.5%, and 55.1 ± 27.1%, respectively. %EWL at 3 months was positively associated with %EWL at 12 and 24 months (P < 0.05). Receiver operating characteristic curve results identified a cut-off of greater than or equal to 30%EWL at 3 months predicted successful weight loss, defined as greater than or equal to 50%EWL at 12 and 24 months.

CONCLUSION

These findings demonstrate that majority of weight loss among adolescents occurs within the first postoperative year. Greater %EWL by 3 months post surgery predicts successful and sustained weight loss over time.

Obesity in Adolescents with Psychiatric Disorders

PURPOSE OF REVIEW

This narrative review synthesized recent research related to obesity in adolescents with psychiatric disorders, with a focus on epidemiology, mechanisms, and weight management approaches. The paper reviews literature on depressive and anxiety disorders, bipolar disorder, and schizophrenia spectrum and other psychotic disorders.

RECENT FINDINGS

Depression has a bidirectional relationship with obesity. Bipolar disorder and schizophrenia spectrum disorders, and their treatments, increase the risk of developing obesity. Mechanisms underlying this weight gain include lifestyle and environmental factors and psychiatric medications, though emerging evidence has also suggested the role of genetic and neuroendocrine processes. Evidence about the most effective treatments for obesity in adolescents with psychiatric disorders remains limited. Adolescents with psychiatric disorders are at high risk for obesity. Close monitoring for increases in weight and cardiometabolic risk factors with use of antipsychotic and mood-stabilizing medications is recommended. Clinical trials are needed that test the efficacy of weight management strategies for this population.

Psychiatric Diagnoses and Weight Loss Among Adolescents Receiving Sleeve Gastrectomy

BACKGROUND AND OBJECTIVES

Severe obesity is associated with higher risk of psychiatric difficulties. Bariatric surgery is the most effective treatment of severe obesity. Few guidelines exist regarding the association of psychiatric diagnoses in adolescents and outcomes after surgery because of the lack of longitudinal research. Our objective is to evaluate the rates of psychiatric diagnoses in adolescents undergoing surgery compared with those not receiving surgery and the association of preoperative psychiatric diagnoses with postsurgical weight loss outcomes.

METHODS

Adolescents (N = 222) referred for psychological evaluation at one institution for bariatric surgery (2009-2017) completed semistructured clinical interviews to assess the presence and number of psychiatric diagnoses. Comparison analyses were conducted between those who did not end up receiving surgery (N = 53) and those who did (N = 169). Using longitudinal modeling, we assessed the association of preoperative diagnoses with weight loss outcomes between 3 and 12 months after surgery.

RESULTS

Seventy-one percent of adolescents qualified for a psychiatric disorder. There were no differences in rates of specific disorders or numbers of diagnoses between those receiving surgery and those not receiving surgery. The presence or absence or number of diagnoses before surgery was not associated with weight loss outcomes after surgery.

CONCLUSIONS

Psychiatric diagnoses are prevalent among adolescents with severe obesity. These diagnoses are not associated with weight loss outcomes. The presurgical psychological evaluation serves as an opportunity to identify adolescents experiencing psychiatric problems and provide them with care but should not necessarily be considered a contraindication to surgery.

Clinical versus patient-reported measures of depression in bariatric surgery

BACKGROUND

Bariatric surgery patients with mental illness may experience worse surgical outcomes compared to those without. Depression is the most prevalent mental health diagnosis amongst Americans with obesity. Accurate diagnosis and treatment is of paramount importance to mitigate perioperative risk. Unfortunately, there is no standard method to screen patients for depression prior to surgery. Our goal was to understand the relationship between traditional clinical screening tools and a novel patient-reported depression screening survey, Patient Health Questionnaire 8 (PHQ-8), in the setting of the bariatric surgery preoperative assessment.

METHODS

The study included all adult bariatric surgery patients from January 2014 through June 2016. Patients who were not assessed using both the PHQ-8 and a traditional clinical depression screening were excluded from the study. There were a total of 4486 patients who met the eligibility criteria and were included in analysis. We used comparative statistics to examine the association between these screening tools and to test for contributing demographic, surgical, and socioeconomic factors.

RESULTS

The overall rate of clinically diagnosed depression in the study cohort was 45.6%. In comparison, 14.8% of all patients screened positive for depression using the PHQ-8. Of the patients without a traditional clinical diagnosis of depression, 10.2% screened positive for depression using the PHQ-8. This subset of undiagnosed patients was more likely to be non-white, employed, and had a higher BMI than their clinically diagnosed counterparts.

CONCLUSIONS AND RELEVANCE

We found a higher rate of clinically diagnosed depression in our cohort compared to the general population. However, when using the validated PHQ-8 survey, the rate of depression more closely approximated the national incidence. Further, a significant proportion of patients were undiagnosed and/or misdiagnosed by current clinical assessments. Standardizing preoperative depression screening using validated patient-centered tools may prevent the consequences of untreated depression.

Shunt freedom and clinical resolution of idiopathic intracranial hypertension after bariatric surgery in the pediatric population: report of 3 cases

Idiopathic intracranial hypertension (IIH), formerly known as pseudotumor cerebri, is a disease of elevated intracranial pressure that is thought to develop due to impaired CSF absorption related to elevated venous sinus pressure in the setting of increased intraabdominal and thoracic pressures. Symptoms can be disabling and, if left untreated, can lead to permanent visual loss. Previous treatments directed toward vision preservation include CSF diversion through shunting and optic nerve sheath fenestration. Recently, attention has been turned toward surgical weight loss strategies as an alternative to shunt treatment. The authors present a report of 3 patients with adolescent-onset IIH that was treated at the authors' institution (Duke University) in whom bariatric surgery was pursued successfully. The patients had previously undergone CSF shunting at ages 12, 15, and 23 years. They were shunt dependent for a collective average of 3.3 years prior to bariatriwc surgery. All patients reported "low-pressure" or postural headaches after bariatric surgery that correlated with dramatic reduction in their weight. Two of the 3 patients had their shunts removed and continued to be shunt free 1.5 years later at last follow-up; the third patient remained shunt dependent with the pressure set at 200 mm H₂O. Given the significant complications inherent to multiple shunt revisions, earlier intervention for weight loss, including bariatric surgery, in these patients might have prevented complications and the associated health care burden. The authors recommend a multidisciplinary approach for IIH treatment with early consideration for weight loss interventions in select patients.

Psychological and lifestyle risk factors for asthma exacerbations and morbidity in children

Asthma is the most common childhood illness and disproportionately affects low-income, minority children who live in urban areas. A range of risk factors are associated with asthma morbidity and mortality, such as treatment non-adherence, exposure to environmental triggers, low-income households, exposure to chronic stress, child psychological problems, parental stress, family functioning, obesity, physical inactivity, and unhealthy diets. These risk factors often have complex interactions and inter-relationships. Comprehensive studies that explore the inter-relationships of these factors in accounting for asthma morbidity and mortality are needed and would help to inform clinical intervention. Considerable research has focused on interventions to improve adherence, asthma management, asthma symptoms, and quality of life for patients with asthma. Educational interventions combined with psychosocial interventions, such as behavioral, cognitive-behavioral, or family interventions, are beneficial and provide care in schools, homes, and emergency rooms can help to address barriers to accessing care for children and families. Additional recent research has explored the use of multidisciplinary, collaborative, integrated care with pediatric asthma patients, providing promising results. Integrated care could be ideal for addressing the multitude of complex psychosocial and wellness factors that play a role in childhood asthma, for increasing patient-centered care, and for promoting collaborative patient-provider relationships. Further research in this area is essential and would be beneficial.

Laparoscopic sleeve gastrectomy for morbidly obese adolescents in Singapore

INTRODUCTION

Laparoscopic sleeve gastrectomy (LSG) outcomes among adolescents and factors associated with adolescent obesity in Singapore were evaluated.

METHODS

Prospectively collected data of patients aged 16-19 years who underwent LSG was retrospectively reviewed. A lifestyle questionnaire, Berlin and Epworth scores, and Patient Health Questionnaire-9 scores were collected. Preoperative anthropometrics, comorbidities, weight loss and body composition outcomes were recorded.

RESULTS

Among 208 LSGs, 13 (6.3%) were performed on obese adolescents. Mean age and body mass index (BMI) at first presentation were 19.1 ± 0.9 (range 16.8-19.8) years and 46.2 ± 6.3 (range 36-57) kg/m², respectively. There was family history of obesity (n = 7) and regular consumption of high-calorie drinks (n = 12). Most patients had comorbidities (n = 12), including hypertension (n = 5), asthma (n = 4), diabetes mellitus (n = 3), hernia (n = 3) and obstructive sleep apnoea requiring continuous positive airway pressure support (n = 3). At one year, excess weight loss was 64.3% ± 34.7% (range 21.8%-101.5%), while BMI and fat mass dropped to 31.2 ± 7.6 (range 23-40) kg/m² and 17.4 kg, respectively. Pain score was 2/10 at 24 hours after surgery. Mean postoperative stay was 2.7 days. No complications or readmissions occurred. Remission of diabetes mellitus and hypertension was reported in two of three and four of five adolescents, respectively, within one year of surgery.

CONCLUSION

LSG is a safe option for adolescents with good short-term weight loss outcomes and remission of metabolic comorbid conditions.

The Team to Address Bariatric Care in Canadian Children (Team ABC3): Team Grant Research Proposal

BACKGROUND

Severe obesity (SO) in Canadian children remains poorly understood. However, based on international data, the prevalence of SO appears to be increasing and is associated with a number of psychosocial, bio-mechanical, and cardiometabolic health risks. The purpose of our national Team to Address Bariatric Care in Canadian Children (Team ABC3) is to develop and lead a series of inter-related studies to enhance the understanding and management of SO in Canadian children and adolescents (0-18 years).

METHODS/DESIGN

From 2015 to 2019, Team ABC3 will conduct a series of projects at the regional, provincial, and national levels using multiple methods and study designs to respond to key knowledge gaps by (i) generating evidence on the prevalence of SO and its impact on health services utilization in children using existing Canadian data sources from primary care settings, (ii) exploring contemporary definitions of SO that link with health outcomes, (iii) comparing and contrasting health risks across the continuum of SO, (iv) understanding potential barriers to and facilitators of treatment success in children with SO, and (v) examining innovative lifestyle and behavioral interventions designed to successfully manage SO in children and their families. Furthermore, to examine the impact of innovative interventions on the management SO, we will (vi) evaluate whether adding a health coach, who provides support via text, email, and/or phone, improves children's ability to adhere to a web-based weight management program and (vii) test the feasibility and impact of a community-based weight management program for pre-school children with SO and their parents that combines group-based parenting sessions with in-home visits.

DISCUSSION

Our research aligns with national priorities in obesity research, brings together leading scientists, clinicians, and stakeholders from across Canada, and will inform health services delivery throughout the country to provide the best care possible for children with SO and their families.

Laparoscopic Roux-en-Y gastric bypass in adolescents with severe obesity (AMOS): a prospective, 5-year, Swedish nationwide study

BACKGROUND

Severe obesity in adolescence is associated with reduced life expectancy and impaired quality of life. Long-term benefits of conservative treatments in adolescents are known to be modest, whereas short-term outcomes of adolescent bariatric surgery are promising. We aimed to compare 5-year outcomes of adolescent surgical patients after Roux-en-Y gastric bypass with those of conservatively treated adolescents and of adults undergoing Roux-en-Y gastric bypass, in the Adolescent Morbid Obesity Surgery (AMOS) study.

METHODS

We did a nationwide, prospective, non-randomised controlled study of adolescents (aged 13-18 years) with severe obesity undergoing Roux-en-Y gastric bypass at three specialised paediatric obesity treatment centres in Sweden. We compared clinical outcomes in adolescent surgical patients with those of matched adolescent controls undergoing conservative treatment and of adult controls undergoing Roux-en-Y gastric bypass. The primary outcome measure was change in BMI over 5 years. We used multilevel mixed-effect regression models to assess longitudinal changes. This trial is registered with ClinicalTrials.gov, number NCT00289705.

FINDINGS

Between April, 2006, and May, 2009, 100 adolescents were recruited to the study, of whom 81 underwent Roux-en-Y gastric bypass (mean age 16·5 years [SD 1·2], bodyweight 132·8 kg [22·1], and BMI 45·5 kg/m² [SD 6·1]). 80 matched adolescent controls and 81 matched adult controls were enrolled for comparison of outcomes. The change in bodyweight in adolescent surgical patients over 5 years was -36·8 kg (95% CI -40·9 to -32·8), resulting in a reduction in BMI of -13·1 kg/m² (95% CI -14·5 to -11·8), although weight loss less than 10% occurred in nine (11%). Mean BMI rose in adolescent controls (3·3 kg/m², 95% CI 1·1-4·8) over the 5-year study period, whereas the BMI change in adult controls was similar to that in adolescent surgical patients (mean change -12·3 kg/m², 95% CI -13·7 to -10·9). Comorbidities and cardiovascular risk factors in adolescent surgical patients showed improvement over 5 years and compared favourably with those in adolescent controls. 20 (25%) of 81 adolescent surgical patients underwent additional abdominal surgery for complications of surgery or rapid weight loss and 58 (72%) showed some type of nutritional deficiency; health-care consumption (hospital attendances and admissions) was higher in adolescent surgical patients compared with adolescent controls. 20 (25%) of 81 adolescent controls underwent bariatric surgery during the 5-year follow-up.

INTERPRETATION

Adolescents with severe obesity undergoing Roux-en-Y gastric bypass had substantial weight loss over 5 years, alongside improvements in comorbidities and risk factors. However, gastric bypass was associated with additional surgical interventions and nutritional deficiencies. Conventional non-surgical treatment was associated with weight gain and a quarter of patients had bariatric surgery within 5 years.

Mental distress in treatment seeking young adults (18-25 years) with severe obesity compared with population controls of different body mass index levels: cohort study

Young adults (18-25) with severe obesity constitute a challenging patient group, and there is limited evidence about their mental health status compared to population controls. Mental distress in treatment seeking young adults with severe obesity (n = 121, mean body mass index [BMI] = 39.8 kg m^-2 ) was compared with matched (1:3 for age, gender and socioeconomic status) population controls of normal weight (n = 363, mean BMI = 22.4 kg m^-2 ), as well as unmatched population controls with class I obesity (n = 105, mean BMI = 32.1 kg m^-2 ) or severe obesity (n = 41, mean BMI = 39.7 kg m^-2 ). Mental distress was measured by the General Health Questionnaire-12 (GHQ-12), and we quantified physician-diagnosed depression, present anxiety and suicide attempts. Poisson regression and linear regression analysis were used for analysing differences in mental distress between groups. Treatment seekers experienced more mental distress than normal weight controls as measured by continuous (adjusted mean: 3.9 vs. 2.2 points, P <0.001) and categorical (cut-off for mental distress ≥3 points, RR: 1.76, P <0.001) GHQ-12 scores, depression (RR: 2.18, P < 0.001), anxiety (RR: 1.97, P < 0.001) and suicide attempts (RR: 2.04; P = 0.034). Treatment seekers also experienced more mental distress as measured by continuous GHQ-12 than controls with class I obesity (adjusted mean: 2.3 points) or severe obesity (adjusted mean: 2.1; both, P < 0.001). Young adult treatment seekers with severe obesity constitute a risk group for mental distress compared to population controls of different BMI levels.

The effect of positive airway pressure therapy on neurocognitive functions, depression and anxiety in obesity hypoventilation syndrome

Background

The aim of this study is to evaluate the presence of neurocognitive dysfunctions, depression and anxiety and the effect of positive airway pressure (PAP) therapy on these alterations in Obesity Hypoventilation Syndrome (OHS) patients.

Methods

Ten healthy normal and obese controls, 10 OHS and 10 OSAS patients were included in the study. Short form-36, Beck Depression Scale and State-Trade Anxiety Inventory (STAI 1-2) were performed. Wisconsin Card Sorting Test (WCST), Montreal Cognitive Assessment Scale (MOCA), Enhanced Cued Recall (ECR) and Mini Mental Test (MMT) were used for neurocognitive evaluation. All tests were repeated after one night PAP therapy in OHS and OSAS groups.

Results

OHS patients had the lowest scores of physical (PF) and social functioning (SF) in SF-36. The total number of persistent errors and incorrect answers were the highest in OHS group in WCST. The scores of MOCA, ECR and MMT were lower; depression and anxiety scores were higher in OHS group than in controls (p = 0,00). There was a significant increase in the completed categories in OHS after PAP therapy (p = 0,03). There were also significant increases in MOCA, ECR and MMT scores and significant decreases in depression and anxiety scores with respect to PAP therapy.

Conclusions

Cognitive dysfunction, depression and anxiety are important under-recognized comorbidities in OHS. It is suggested that short term PAP therapy had positive effects on neurocognitive functions, depression and anxiety but further multicentre, prospective studies with large number of cases are needed to evaluate the effect of long term PAP therapy on these parameters.

Overweight and Underweight Prevalence Trends in Children from Romania - Pooled Analysis of Cross-Sectional Studies between 2006 and 2015

AIM

High-quality national representative data on obesity in Romanian children are needed to shape public health policies. To provide a unified data landscape on national prevalence, trends and other factors associated with underweight, overweight, and obesity in Romanian children aged 6-19 years, across the last decade (2006-2015).

METHODS

Using a common protocol, we selected published and unpublished studies that measured Romanian children in schools between 2006 and 2015. Children's BMI was classified using the current WHO, IOTF, and CDC references.

RESULTS

25,060 children from 8 Romanian counties were included in the analysis. The prevalence of underweight children was 5%/4.5%/8.5% (WHO/IOTF/CDC), while the prevalence of overweight (including obese) children was 28.3%/23%/23.2% (WHO/IOTF/CDC). The prevalence of overweight children did not change significantly over the last decade (chi-square test p = 0.6). Male gender (odds ratio (OR) 1.37; 95% CI 1.29-1.45, compared to female); prepubertal age (OR = 3.86; 95% CI 3.41-4.36,compared to postpubertal age), and urban environment (OR 1.12; 95% CI 1.01-1.26, compared to rural environment) had higher risk for overweight.

CONCLUSION

While the prevalence of underweight children was low, almost one in four children in Romania was overweight or obese (according to WHO criteria) between 2006 and 2015. This prevalence remained relatively stable over the last decade. Male gender, prepubertal age, and urban environment, were the most relevant risk factors associated with overweight status in Romanian children.

BMI, Body Image, Emotional Well-Being and Weight-Control Behaviors in Urban African American Adolescents

IMPORTANCE

While urban African American adolescents face significant health disparities associated with overweight and obesity that follow them into adulthood; there is limited data on body image, emotional well-being, and weight control behaviors in this population to design effective public health interventions.

OBJECTIVE

This study was designed to understand the association of weight status to adolescent weight control, body image, and emotional well-being responses, in African American high school students.

DESIGN/SETTING/PARTICIPANTS

The study cohort consisted of 776 students, mean age 15.8 years (±1.2). Data from Guidelines for Adolescent Preventive Services (GAPS) student surveys and anthropometric studies were collected at School-Based Health Centers.

MAIN OUTCOME MEASURES

Associations between adolescent responses on the GAPS and body mass index (BMI) status (healthy weight: 5th to less than 85th percentile, overweight: 85th to less than 95th percentile, obese: 95th percentile or greater) were estimated using logistic regression and dose- response plots.

RESULTS

There were statistically significant associations between BMI category and weight control (ranging from a mean 5.18 to 7.68 odds of obesity) and body image (3.40 to 13.26 odds of obesity) responses. Responses to weight control and body image questions exhibited a dose-response for odds of overweight and obesity. Feelings of depressed mood were associated with obesity (1.47 times the odds of obesity compared to students who did not endorse depressed mood; 95% CI, 1.01 to 2.13) but not overweight status.

CONCLUSION AND RELEVANCE

Overweight and obese urban African American adolescents are more likely to screen positively on weight control risk behaviors and negative body image questions than their normal weight peers. The weight control and body image measures on the GAPS may provide information to identify youth in need of services and those motivated for brief school-based weight control interventions.

Who is the Treatment-Seeking Young Adult with Severe Obesity: A Comprehensive Characterization with Emphasis on Mental Health

OBJECTIVE

To characterize treatment-seeking young adults (16-25 years) with severe obesity, particularly mental health problems.

STUDY DESIGN AND PARTICIPANTS

Cross-sectional study of 165 participants (132 women, 33 men) with BMI ≥35 kg/m2 or ≥30 kg/m2 with comorbidities, enrolling in a multidisciplinary obesity treatment program.

METHOD

Data collection at admission of present and life-time health issues including symptomatology of anxiety, depression (Hospital Anxiety and Depression Scale) and attention-deficit/hyperactivity disorder (Adult ADHD Self-Report scale); self-esteem (Rosenberg Self-Esteem Scale), suicide attempts, health-related quality of life (Short Form-36 Health Survey), psychosocial functioning related to obesity (Obesity-related Problems Scale), cardiorespiratory fitness (Astrand's bicycle ergometer test), somatic and psychiatric co-morbidities, cardiometabolic risk factors, and micronutritional status. We used multiple regression analysis to identify variables independently associated with present anxiety and depressive symptomatology.

RESULTS

Mean body mass index was 39.2 kg/m2 (SD = 5.2). We found evidence of poor mental health, including present psychiatric diagnoses (29%), symptomatology of anxiety (47%), depression (27%) and attention-deficit/hyperactivity disorder (37%); low self-esteem (42%), attempted suicide (12%), and low quality of life (physical component score = 46, SD = 11.2; mental component score = 36, SD = 13.9, P<0.001 for difference). Variables independently associated with present anxiety symptomatology (R2 = 0.33, P<0.001) included low self-esteem (P<0.001) and pain (P = 0.003), whereas present depressive symptomatology (R2 = 0.38, P<0.001) was independently associated with low self-esteem (P<0.001), low cardiorespiratory fitness (P = 0.009) and obesity-related problems (P = 0.018). The prevalence of type 2 diabetes was 3%, and hypertension 2%. Insulin resistance was present in 82%, lipid abnormality in 62%, and poor cardiorespiratory fitness in 92%. Forty-eight percent had at least one micronutritional deficiency, vitamin D being the most common (35%).

CONCLUSION

A wide range of health issues, including quite severe mental health problems, was prevalent in treatment-seeking young adults with severe obesity. These are likely to constitute a major treatment challenge, including options relating to bariatric surgery.

Two-year trends in psychological outcomes after gastric bypass in adolescents with severe obesity

OBJECTIVE

This study aimed to evaluate changes in mental health over 2 years in adolescents undergoing gastric bypass.

METHODS

Eighty-eight adolescents (65% girls) aged 13 to 18 years were assessed at baseline and 1 and 2 years after surgery. Generic and obesity-specific questionnaires were used to evaluate outcomes in mental health, also in relation to age- and gender-specific norms.

RESULTS

Symptoms of anxiety (P = 0.001), depression (P = 0.001), anger (P = 0.001), and disruptive behavior (P = 0.022) were significantly reduced at 2 years after surgery, as were obesity-related problems (P < 0.001). Self-esteem (P < 0.001), self-concept (P < 0.001), and overall mood (P = 0.025) improved significantly. Improvements were mainly observed during the first year after surgery. The second year was characterized by stabilization. Symptoms of anxiety, depression, anger, disruptive behavior, and self-concept were at normative levels after surgery. However, 19% of the adolescents had depressive symptoms in the clinical range.

CONCLUSIONS

A substantial improvement in mental health in adolescents over the first 2 years after gastric bypass was found. Most adolescents had a level of mental health and self-concept similar to norms, but a marked subgroup showed substantial depressive symptoms 2 years after surgery.
