Experiences of loss of control eating in women after bariatric surgery: A qualitative study.

OBJECTIVE: Loss of control (LOC) eating following bariatric surgery remains insufficiently understood, reflected in a lack of clear conceptualization, valid measurements, and effective treatments. This study explored patients' perspectives on LOC eating post-bariatric surgery, focusing on the relevance of the Diagnostic and Statistical Manual of Mental Disorders-5 (DSM-5) indicators of impaired control, and patients' experiences before (precipitating factors), during (eating patterns, perpetuating factors), and after the episodes (strategies used to stop eating). METHODS: This was a qualitative study using descriptive phenomenology. Participants were adults who have undergone gastric bypass or sleeve gastrectomy and self-reported recent LOC eating. Data were collected by semi-structured interviews and analyzed using a combined inductive and deductive approach. RESULTS: Participants were all women (N = 15; age: 34.5 ± 9.2 years). Results suggested that (1) except for feeling disgusted, guilty, or depressed after eating, other DSM-5 indicators did not seem to be highly relevant to this bariatric cohort; (2) LOC eating could occur across contexts, with food access, boredom, and food craving being consistent triggers; (3) the food amount consumed during a LOC episode was not necessarily considered excessive; (4) "mindlessness" and "satisfying hedonic, physiological, and mental needs" were the main perpetuating factors of LOC eating; and (5) self-talk and distracting attention were the most adopted strategies to stop eating. DISCUSSION: Study findings have implications concerning the conceptualization, measurement, and intervention of LOC eating among bariatric patients. For example, results suggested the need for more data to determine the appropriate indicators of LOC eating and the inclusion of boredom as an intervention target in bariatric patients. PUBLIC SIGNIFICANCE: Loss of control (LOC) eating is characterized by a sense of being unable to stop while eating. LOC eating is prevalent in patients who have undergone weight loss surgery and is associated with worse surgical outcomes. This qualitative study that explored post-bariatric surgery patients' experiences of LOC eating will inform efforts to better assess and intervene in this disordered eating behavior, thus ultimately optimizing patients' health following weight loss surgery.

Healthy measures: Feasibility study of a moderate carbohydrate weight management intervention.

BACKGROUND: People of all weights need to prevent changes that could lead to obesity, a leading public health issue. OBJECTIVE: To assess the feasibility of Healthy Measures, a moderate carbohydrate (160-300 g/d) nutrition education and behavioral intervention. DESIGN: An uncontrolled intervention feasibility study including in-person group meetings every 2 weeks for 3 months. SAMPLE: Fifteen participants of normal and overweight BMI. MEASUREMENTS: We assessed feasibility of recruitment, attendance, retention and satisfaction as well as anthropometric measures and social cognitive variables with Healthy Measures, a nutrition-focused intervention with moderate carbohydrate portions that also emphasizes self-monitoring of anthropometric measurements. An intent-to-treat analysis was used. RESULTS: Healthy Measures was feasible, with 13 participants (86.7%) completing pre- and post-intervention assessments. Eight participants lost or maintained weight (53.3%); four gained weight. Healthy eating self-efficacy increased overall (t = -2.54, p = .024). Increased protein and fat intake was associated with weight loss, while reduced protein, carbohydrate, and fat intake resulted in weight gain. CONCLUSIONS: Healthy Measures shows promise for prevention of weight gain, with evidence of feasibility and positive outcomes. Further research is needed to establish efficacy relative to alternative approaches.

Perceptions and experiences of appetite awareness training among African-American women who binge eat.

INTRODUCTION: Binge eating may contribute to the prevalence of obesity in African-American women. Yet, there has been scant intervention research on the treatment of binge eating in this population. We tested the feasibility of an appetite awareness training (AAT) intervention in a sample of African-American women with binge and overeating behaviors. Participants who completed AAT were recruited to participate in focus groups to elicit information about their perceptions and experiences with this intervention to inform the design of future interventions to treat binge eating and obesity in African-American women. METHODS: African-American women, aged 18-70 years, who had completed an 8-week randomized AAT intervention, were invited to attend a focus group discussion. Session content was recorded and transcribed. Data were analyzed by use of open coding. Themes were identified that described their perceptions and experiences of participating in the intervention. RESULTS: Seventeen women participated in three focus group discussions. Pertinent themes identified included: paying attention to internal cues of hunger and satiety, influence of culture on eating patterns, breaking patterns of disordered eating, and perceptions about weight. Overall, participants were satisfied with their experience of AAT, and reported they found it valuable to learn about listening to biological signals of hunger and satiety and to learn specific strategies to reduce maladaptive eating patterns. CONCLUSION: AAT was acceptable and provided helpful eating behavior instruction to African-American women with reported binge and overeating behaviors. Future research should examine the potential of AAT to improve weight management in this underserved population. LEVEL OF EVIDENCE: Level V, qualitative descriptive study.

Eating pathology and associations with long-term changes in weight and quality of life in the longitudinal assessment of bariatric surgery study.

OBJECTIVE: This study examines the course of eating pathology and its associations with change in weight and health-related quality of life following bariatric surgery. METHOD: Participants (N = 184) completed the eating disorder examination-bariatric surgery version (EDE-BSV) and the medical outcomes study 36-Item short form health survey (SF-36) prior to and annually following Roux-en-Y gastric bypass (RYGB) or laparoscopic adjustable gastric banding (LAGB) for up to 7 years. RESULTS: The prevalence of ≥ weekly loss of control (LOC) eating, picking/nibbling, and cravings declined post-RYGB and remained lower through 7 years (LOC: 5.4% at Year-7 vs. 16.2% pre-RYGB, p = .03; picking/nibbling: 7.0% vs. 32.4%, p < .001; and cravings: 19.4% vs. 33.6%, p = .02). The prevalence of picking/nibbling was significantly lower 7 years following LAGB vs. pre-LAGB (29.4% vs 45.8%, p = .049), while cravings (p = .13) and LOC eating (p = .95) were not. EDE-BSV global score and ratings of hunger and enjoyment of eating were lower 7 years following both RYGB and LAGB versus pre-surgery (p's for all <.05). LOC eating following RYGB was associated with less long-term weight loss from surgery (p < .01) and greater weight regain from weight nadir (p < .001). Higher post-surgery EDE-BSV global score was associated with less weight loss/greater regain (both p < .001) and worsening/less improvement from surgery in the SF-36 mental component summary scores (p < .01). DISCUSSION: Initial improvements in eating pathology following RYGB and LAGB were sustained across 7 years of follow-up. Individuals with eating pathology post-RYGB, reflected by LOC eating and/or higher EDE-BSV global score, may be at risk for suboptimal long-term outcomes.

The Impact of Patient Characteristics and Postoperative Opioid Exposure on Prolonged Postoperative Opioid Use: An Integrative Review.

OBJECTIVES: The United States is experiencing an opioid overdose crisis. Research suggests prolonged postoperative opioid use, a common complication following surgery, is associated with opioid misuse, which, in turn, is the greatest risk factor of heroin misuse. The objective of this review is to evaluate how postoperative opioid exposure relates to prolonged use and to identify factors that predict prolonged postoperative opioid use. DESIGN: An integrative review of the literature. DATA SOURCES: Electronic and hand searching methods were used in PubMed, Embase, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, CINAHL, and SCOPUS. Search terms included opioid, opiate, postoperative pain, drug administration, prescribing pattern, prescription, inappropriate prescribing, self-medication, patient-controlled analgesia, opioid-naïve patients, and prolonged opioid use. REVIEW/ANALYSIS METHODS: Data were synthesized by identifying themes reflecting the results of the review. A quality assessment of the articles was also conducted. RESULTS: Fourteen articles were included and two main themes emerged: (1) Surgery places opioid naïve patients at risk for prolonged opioid use and (2) Certain patient characteristics may be predictive of prolonged postoperative opioid use. CONCLUSIONS: Prolonged postoperative opioid use is related to factors in addition to prescribing practices. Researchers consistently found that patients who are already on opioids, benzodiazepines, or addicted to alcohol; who have mental health disorders, depressive symptoms, or a self-perceived risk of addiction; and patients with multiple co-morbidities are at greater risk of prolonged use; demographics were inconsistent. NURSING IMPLICATIONS: Studies are needed to determine the predicting characteristics of prolonged postoperative opioid use, the type of surgeries that place patients at most risk, and the effect postoperative exposure to opioids has on prolonged use. This information can be used to develop and implement protocols to prevent misuse among high-risk patients.

Psychiatric Disorders and Weight Change in a Prospective Study of Bariatric Surgery Patients: A 3-Year Follow-Up.

OBJECTIVES: To document changes in Axis I psychiatric disorders after bariatric surgery and examine their relationship with postsurgery weight loss. METHODS: As part of a three-site substudy of the Longitudinal Assessment of Bariatric Surgery Research Consortium, 199 patients completed the Structured Clinical Interview for DSM-IV before Roux-en-Y gastric bypass or laparoscopic adjustable gastric band. At 2 or 3 years after surgery, 165 (83%) patients completed a follow-up assessment (presurgery median body mass index = 44.8 kg/m, median age = 46 years, 92.7% white, 81.1% female). Linear-mixed modeling was used to test change in prevalence of psychiatric disorders over time, report remission and incidence, and examine associations between psychiatric disorders and weight loss. RESULTS: Compared with status presurgery, the prevalence of any Axis I psychiatric disorder was significantly lower at 2 and 3 years after surgery (30.2% versus 16.8% [p = .003] and 18.4% [p = .012], respectively). Adjusting for site, age, sex, race, presurgery body mass index, and surgical procedure, presurgery mood, anxiety, eating or substance use disorders (lifetime or current) were not related to weight change, nor were postsurgery mood or anxiety disorders (p for all > .05). However, having a postsurgery eating disorder was independently associated with less weight loss at 2 or 3 years (ß = 6.7%, p = .035). CONCLUSIONS: Bariatric surgery was associated with decreases in psychiatric disorders through 3 years after surgery. Postsurgical eating disorders were associated with less weight loss after surgery, adding to the literature suggesting that disordered eating after surgery is related to suboptimal weight loss.

Eating pathology and experience and weight loss in a prospective study of bariatric surgery patients: 3-year follow-up.

OBJECTIVE: Bariatric surgery results in significant long-term weight loss, albeit with considerable variability. This study examines the prognostic significance of eating pathology as determined by a structured interview, the Eating Disorder Examination-Bariatric Surgery Version (EDE-BSV). METHOD: Participants (N = 183) in this substudy of the Longitudinal Assessment of Bariatric Surgery (LABS) Research Consortium were assessed using the EDE-BSV, independent of clinical care, presurgery and annually postsurgery. We examined eating pathology and experiences at several frequency thresholds (present, ≥ monthly, ≥ weekly) over 3 years, and utilized mixed models to test their associations with percentage weight loss from baseline at years 1, 2, and 3. RESULTS: The prevalence of several forms of eating pathology declined pre- to 1-year postsurgery, including ≥weekly objective bulimic episodes (11.6-1.3%), loss of control (LOC) eating (18.3-6.2%) and picking/nibbling (36.0-20.2%) (P for all <0.01), and regular evening hyperphagia (16.5-5.0%, P = 0.01), but not cravings (P = 0.93). Mean EDE global score, and hunger and enjoyment scores, also declined (P for all <0.01). These metrics remained lower than baseline through year-3 (P for all <0.01). Presurgery eating variables were not related to weight loss (P for all ≥0.05). However, postsurgery higher EDE global score and greater hunger were independently associated with less weight loss postsurgery (P for both ≤0.01), while cravings were associated with greater weight loss (P = 0.03). DISCUSSION: Pathological eating behaviors and experiences are common presurgery and improve markedly following surgery. Postsurgery pathological eating-related experiences and attitudes and hunger may contribute to suboptimal weight loss. © 2016 Wiley Periodicals, Inc. (Int J Eat Disord 2016; 49:1058-1067).

Wise Choices: Nutrition and Exercise for Older Adults: A Community-Based Health Promotion Intervention.

Effective interventions for older adults are needed to address lifestyle behaviors linked to chronic illnesses. We implemented a 12-week group behavioral intervention for 118 racially diverse older adults at 6 community-based senior centers to improve eating and physical activity. Assessments were completed pre- and postintervention, with 85.6% retention. We documented increases in fruit, vegetable, and whole grain intake; pace of walking; number of city blocks walked; daily steps walked; functional mobility; and self-rated general health (P < .05). Findings indicate that a relatively low-intensity lifestyle intervention can effectively be implemented for community-dwelling older adults. Further development of this approach is warranted.

Eating behavior and eating disorders in adults before bariatric surgery.

OBJECTIVE: To describe eating patterns, prevalence of problematic eating behaviors, and determine factors associated with binge eating disorder (BED), before bariatric surgery. METHOD: Before surgery, 2,266 participants (median age 46 years; 78.6% female; 86.9% white; median body mass index 45.9 kg/m(2) ) of the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2) study completed eating behavior survey items in the self-administered LABS-2 Behavior form. Other measures included the Alcohol Use Disorder Identification Test, the LABS-2 Psychiatric and Emotional Test Survey, the Beck Depression Inventory, the Interpersonal Support Evaluation List-12, the Short Form-36 Health Survey, and Impact of Weight Quality of Life-Lite Survey. RESULTS: The majority (92.1%) of participants reported eating dinner regularly, whereas just over half (54.0%) reported eating breakfast regularly. Half of the participants reported eating at least four meals/week at restaurants; two meals/week were fast food. Loss of control eating was reported by 43.4%, night eating syndrome by 17.7%; 15.7% satisfied criteria for binge eating disorder (BED), 2% for bulimia nervosa. Factors that independently increased the odds of BED were being a college graduate, eating more times per day, taking medication for psychiatric or emotional problems, and having symptoms of alcohol use disorder, lower self-esteem and greater depressive symptoms. DISCUSSION: Before undergoing bariatric surgery a substantial proportion of patients report problematic eating behaviors. Several factors associated with BED were identified, most suggesting other mental health problems, including higher levels of depressive symptomotology. The strengths of this study include the large sample size, the multi-center design and use of standardized assessment practices.

Binge eating disorder and medical comorbidities in bariatric surgery candidates.

OBJECTIVE: To determine whether binge eating disorder (BED) status is associated with medical comorbidities in obese adults scheduled for bariatric surgery. METHOD: The study utilized Longitudinal Assessment of Bariatric Surgery-2 data obtained from six clinical centers around the United States. This is a well-phenotyped cohort of individuals who were evaluated within 30 days before their scheduled surgery using standardized protocols. In the cohort, 350 participants were classified as having BED and 1,875 as not having BED (non-BED). Multivariable logistic regression was used to determine whether BED status was independently related to medical comorbidities. As an exploratory analysis, significance was based on nominal p-values (p < .05). Holm's-adjusted p-values were also reported. RESULTS: After adjusting for age, sex, education, and body mass index, BED status was found to be independently associated with four of the 15 comorbidities (i.e., impaired glucose levels (odds ratio [OR] = 1.45 (95% confidence interval [CI]: 1.12-1.87)), high triglycerides (OR = 1.28 (95% CI: 1.002-1.63)), and urinary incontinence (OR = 1.30 (95% CI: 1.02-1.66)), all being more common among the BED sample, and severe walking limitations being less common in the BED sample (OR = 0.53 (95% CI: 0.29-0.96)). With further adjustment for psychiatric/emotional health indicators, BED status was independently associated with three comorbidities (impaired glucose levels (OR = 1.36 (95% CI: 1.04-1.79)), cardiovascular disease (OR = 0.50 (95% CI: 0.30-0.86)), and severe walking limitations (OR = 0.38 (95% CI: 0.19-0.77)). However, Holm's-adjusted p-values for all variables were greater than .05. DISCUSSION: The results suggest the possibility of a contribution of BED to risk of specific medical comorbidities in severely obese adults.

Psychosocial Interventions Pre and Post Bariatric Surgery.

Despite positive results overall, a substantial number of patients experience poor long-term outcomes following bariatric surgery. One reason for variability in weight loss may be difficulty in making and sustaining changes in dietary intake and physical activity; post-surgery binge eating has also been associated with poorer weight outcomes. In this paper, we review available evidence on adjunctive psychosocial interventions for bariatric surgery patients. Although the literature is limited, evidence suggests that bariatric surgery patients may benefit from a comprehensive approach targeting diet, activity and psychological factors. We think the optimal time to initiate adjunctive intervention is after surgery, but before significant weight regain has occurred. Adaptive interventions incorporating advances in technology may prove to be effective for promoting behavioural self-management and psychosocial adjustment following bariatric surgery. For some patients, pharmacotherapy and reoperation may also play a role in a personalized approach to post-surgery care.

Lifestyle management for enhancing outcomes after bariatric surgery.

Bariatric surgery has been safe and effective for treatment of severe obesity and comorbidities like type 2 diabetes mellitus (T2D). Nonetheless, weight loss and health outcomes vary considerably across individuals. Although the factors associated with outcomes are not fully understood, postoperative weight loss following any type of bariatric surgery is largely dependent on the extent to which patients can make and sustain changes in eating and activity. Therefore, lifestyle management including diet, exercise, and behavior modification is critical to helping patients achieve long-term weight loss. Pharmacotherapy and reoperation may also play a role after bariatric surgery. In this article, we highlight recent research findings in all of these areas to provide suggestions for how to enhance outcomes following bariatric surgery. Research on the mechanisms for weight loss and improvements in T2D following the different surgical procedures is needed to support the development of more personalized approaches to the multidisciplinary management of severe obesity.

Impact of a Professional Development Course for Doctoral Nurses and Students on Genomic Conceptual Knowledge and Competencies.

BACKGROUND: Universally, nurses' limited educational opportunities to expand their genomic literacy may have implications on patient care management, research, and training. PURPOSE: To evaluate the impact of a self-paced online course on genomic knowledge and competency acquisition in a sample of nurses possessing a doctoral degree and doctoral students. METHODS: Pre- and postcourse data were collected using the "Genomic Nursing Concept Inventory" (GNCI) (N = 129) and a self-report survey based on the Essential Genetic and Genomic Competencies for Nurses with Graduate Degrees (N = 131). RESULTS: GNCI scores in all 4 topical categories and in 9 of the 16 domains significantly improved. All Genetic Competency scores significantly improved. Significant correlations were observed between Genetic Competency self-ratings and GNCI scores precourse and change of scores. CONCLUSIONS: The positive outcomes should encourage the development of more accessible educational opportunities for nurses and other healthcare professionals to improve genomic literacy and competency.

Food and alcohol disturbance among people who have undergone bariatric surgery.

There have been numerous investigations of aberrant eating and substance abuse among patients who have undergone bariatric surgery, which affects the metabolism and the pharmacokinetics of alcohol. However, there is a dearth of literature considering the complex interplay between changes in post-surgery food and alcohol consumption. Furthermore, despite the increasing recognition of issues surrounding replacing food consumption with alcohol consumption (Food and Alcohol Disturbance [FAD]), most emerging research has focused on young adult populations. This perspective reviews and synthesizes the small but growing body of research on the interplay between food and alcohol consumption, particularly FAD, and considers its application to bariatric surgery in general. There are unique considerations for patients who have undergone bariatric surgery. Patients experience altered gastric anatomy, which affects food and alcohol metabolism, and are advised to abstain from drinking alcohol after surgery. After reviewing the available literature, this perspective highlights future directions for research and practice in bariatric surgery.

Back to the basics: Guidance for designing good literature searches.

The number of scientific publications is growing at an unprecedented rate. Failure to properly evaluate existing literature at the start of a project may result in a researcher wasting time and resources. As pharmacy researchers and scholars look to conceptualize new studies, it is imperative to begin with a high-quality literature review that reveals what is known and unknown about a given topic. The purpose of this commentary is to provide useful guidance on conducting rigorous searches of the literature that inform the design and execution of research. Guidance for less formal literature reviews can be adapted from best practices utilized within the formalized field of evidence synthesis. Additionally, researchers can draw on guidance from PRESS (Peer Review of Electronic Search Strategies) to engage in self-evaluation of their search strategies. Finally, developing an awareness of common pitfalls when designing literature searches can provide researchers with confidence that their research is designed to fill clearly articulated gaps in knowledge.

Weight change and health outcomes at 3 years after bariatric surgery among individuals with severe obesity.

IMPORTANCE: Severe obesity (body mass index [BMI] ≥35) is associated with a broad range of health risks. Bariatric surgery induces weight loss and short-term health improvements, but little is known about long-term outcomes of these operations. OBJECTIVE: To report 3-year change in weight and select health parameters after common bariatric surgical procedures. DESIGN AND SETTING: The Longitudinal Assessment of Bariatric Surgery (LABS) Consortium is a multicenter observational cohort study at 10 US hospitals in 6 geographically diverse clinical centers. PARTICIPANTS AND EXPOSURE: Adults undergoing first-time bariatric surgical procedures as part of routine clinical care by participating surgeons were recruited between 2006 and 2009 and followed up until September 2012. Participants completed research assessments prior to surgery and 6 months, 12 months, and then annually after surgery. MAIN OUTCOMES AND MEASURES: Three years after Roux-en-Y gastric bypass (RYGB) or laparoscopic adjustable gastric banding (LAGB), we assessed percent weight change from baseline and the percentage of participants with diabetes achieving hemoglobin A1c levels less than 6.5% or fasting plasma glucose values less than 126 mg/dL without pharmacologic therapy. Dyslipidemia and hypertension resolution at 3 years was also assessed. RESULTS: At baseline, participants (N = 2458) were 18 to 78 years old, 79% were women, median BMI was 45.9 (IQR, 41.7-51.5), and median weight was 129 kg (IQR, 115-147). For their first bariatric surgical procedure, 1738 participants underwent RYGB, 610 LAGB, and 110 other procedures. At baseline, 774 (33%) had diabetes, 1252 (63%) dyslipidemia, and 1601 (68%) hypertension. Three years after surgery, median actual weight loss for RYGB participants was 41 kg (IQR, 31-52), corresponding to a percentage of baseline weight lost of 31.5% (IQR, 24.6%-38.4%). For LAGB participants, actual weight loss was 20 kg (IQR, 10-29), corresponding to 15.9% (IQR, 7.9%-23.0%). The majority of weight loss was evident 1 year after surgery for both procedures. Five distinct weight change trajectory groups were identified for each procedure. Among participants who had diabetes at baseline, 216 RYGB participants (67.5%) and 28 LAGB participants (28.6%) experienced partial remission at 3 years. The incidence of diabetes was 0.9% after RYGB and 3.2% after LAGB. Dyslipidemia resolved in 237 RYGB participants (61.9%) and 39 LAGB participants (27.1%); remission of hypertension occurred in 269 RYGB participants (38.2%) and 43 LAGB participants (17.4%). CONCLUSIONS AND RELEVANCE: Among participants with severe obesity, there was substantial weight loss 3 years after bariatric surgery, with the majority experiencing maximum weight change during the first year. However, there was variability in the amount and trajectories of weight loss and in diabetes, blood pressure, and lipid outcomes. TRIAL REGISTRATION: clinicaltrials.gov Identifier: NCT00465829.

Mindfulness Self-Compassion: Helping Family Caregivers Cope with Cognitive Behaviors of Dementia.

Purpose: To test the feasibility of recruiting dementia family caregivers to participate in the holistic intervention of mindfulness self-compassion (MSC) to decrease perceived distress. There are few studies focused on MSC for dementia caregivers. Design: An interdisciplinary approach (nursing and psychology) and uncontrolled experimental design tested a holistic intervention Mindfulness Self Compassion (MSC) as a coping strategy using the Stress Process framework. Findings: Twenty-four caregivers participated. Dementia caregivers' use of positive reappraisal increased with a mean difference of 2.53 (t = 2.10; SD = 5.23) (p = .049) indicating that family caregivers may have increased their use of positive reappraisal. MSC sessions impacted the caregivers ways of coping with increases in accepting responsibility [model: F(4, 13) 3.18, p-value 0.0499, R-sq = 49.5%, estimate: B = 1.11, t = 2.64, p-value = 0.02)] and impacted caregivers' ways of coping using distancing [model: F(4, 13) 1.47, p-value 0.2682, R-sq = 31.1%, estimate: B = 1.63, t = 2.19, p-value = 0.05)]. Conclusion: Satisfaction with MSC was high among caregivers. At the study's conclusion, caregivers appraised their caregiving non-judgmentally and reduced their negative thoughts of difficult situations. MSC as a holistic practice has the potential to shift caregivers' focus to positive appraisals and promote caregiver wellbeing.

Psychiatric comorbidity of childhood obesity.

The onset of psychiatric symptoms and disorders is relatively common in childhood, occurring among youths across the weight spectrum. However, available research suggests that certain psychiatric comorbidities are more prevalent in obese children and adolescents than in healthy weight youths. First, we review research on disordered eating, including evidence to suggest that loss of control eating is associated with weight gain and obesity in youths, as well as poor outcome in family-based treatment of paediatric obesity. Second, we highlight evidence on the relationship between depression and obesity, especially in girls. Third, we present data on attention deficit hyperactivity disorder (ADHD), particularly the symptoms of impulsivity and inattention, and childhood obesity. We also consider that some medical conditions and psychotropic medications contribute to weight gain and obesity in children and adolescents. Throughout the review, we emphasize that psychiatric comorbidity may be a cause or consequence of childhood obesity, or they may share common aetiological factors.
