Childhood Maltreatment in Extremely Obese Male and Female Bariatric Surgery Candidates**

Objective: To examine rates of self‐reported childhood maltreatment in extremely obese bariatric surgery candidates and to explore associations with sex, eating disorder features, and psychological functioning. Research Methods and Procedures: Three hundred forty (58 men and 282 women) extremely obese consecutive candidates for gastric bypass surgery completed a questionnaire battery. The Childhood Trauma Questionnaire was given to assess childhood maltreatment. Results: Overall, 69% of patients self‐reported childhood maltreatment: 46% reported emotional abuse, 29% reported physical abuse, 32% reported sexual abuse, 49% reported emotional neglect, and 32% reported physical neglect. Except for higher rates of emotional abuse reported by women, different forms of maltreatment did not differ significantly by sex. Different forms of maltreatment were generally not associated with binge eating, current BMI, or eating disorder features. At the Bonferonni‐corrected significance level, emotional abuse was associated with higher eating concerns and body dissatisfaction, and emotional neglect was associated with higher eating concerns. In terms of psychological functioning, at the Bonferonni‐corrected level, emotional abuse and emotional neglect were associated with higher depression and lower self‐esteem, and physical abuse was associated with higher depression. Discussion: Extremely obese bariatric surgery candidates reported rates of maltreatment comparable with those reported by clinical groups and roughly two to three times higher than normative community samples. Reported experiences of maltreatment differed little by sex and were generally not significantly associated with current BMI, binge eating, or eating disorder features. In contrast, maltreatment—notably emotional abuse and neglect—were significantly associated with higher depression and lower self‐esteem.     

Teasing History,Onset of Obesity,Current Eating Disorder Psychopathology,Body Dissatisfaction,and Psychological Functioning in Binge Eating Disorder

Objective: The primary goal of this study was to examine associations among teasing history, onset of obesity, current eating disorder psychopathology, body dissatisfaction, and psychological functioning in women with Binge Eating Disorder (BED). Research Methods and Procedures: Subjects were 115 female adults who met DSM‐IV criteria for BED. Measurements assessing teasing history (general appearance [GAT] and weight and size [WST] teasing), current eating disorder psychopathology (binge frequency, eating restraint, and concerns regarding eating, shape, and weight), body dissatisfaction, and psychological functioning (depression and self‐esteem) were obtained. Results: History of GAT, but not WST, was associated with current weight concerns and body dissatisfaction, whereas both GAT and WST were significantly associated with current psychological functioning. Patients with earlier onset of obesity reported more WST than patients with later onset of obesity, but the groups did not differ significantly in GAT, current eating disorder psychopathology, body dissatisfaction, or psychological functioning. Obese women reported more WST than non‐obese women, but no differences in GAT or the other outcome variables were observed. Higher frequency of GAT was associated with greater binge frequency in obese women, and with greater eating restraint in non‐obese women. Discussion: Although physical appearance teasing history is not associated with variability in most eating disorder psychopathology, it is associated with related functioning, most notably body dissatisfaction, depression, and self‐esteem. Our findings also suggest that the age of onset of obesity and current body mass index status in isolation are not associated with eating psychopathology or associated psychological functioning in adult patients with BED.     

On the Relation of Attempting to Lose Weight,Restraint, and Binge Eating in Outpatients with Binge Eating Disorder

Objective: To examine the relationship among attempts to lose weight, restraint, and eating behavior in outpatients with binge eating disorder (BED). Research Methods and Procedures: Participants were 93 consecutive outpatients evaluated for a clinical trial who met Diagnostic and Statistical Manual, Fourth edition criteria for BED. The Eating Disorder Examination Interview was administered to assess attempts at weight loss, restraint, different forms of overeating, and the attitudinal psychopathology of eating disorders (i.e., concerns regarding eating, shape, and weight). In addition, the Three‐Factor Eating Questionnaire was used to assess cognitive restraint, hunger, and disinhibition. Psychometrically established measures were given to assess body dissatisfaction, depression, and self‐esteem. Results: The majority of participants (75.3%; N = 70) reported attempting to lose weight, but only 37.6% (N = 35) reported dietary restraint on at least half the days of the month. Dietary restraint and cognitive restraint were not associated with any form of binge eating or overeating. Dietary restraint and cognitive restraint were positively correlated with weight concern, shape concern, and body dissatisfaction, and negatively correlated with body mass index. To further examine the interplay between attempting to lose weight and restraint, three study groups were created: unrestrained nonattempters (21.5%, N = 20), unrestrained attempters (40.9%; N = 38), and restrained attempters (34.4%; N = 32). The three groups did not differ significantly on binge eating or other eating behaviors; however, significant differences were observed for weight concern, shape concern, and body dissatisfaction. Discussion: Attempts to lose weight and restraint are not synonymous for patients with BED. Although 75.3% of BED patients reported that they were attempting to lose weight, only 37.6% reported dietary restraint on at least half the days of the previous month. While restraint was negatively associated with body mass index, it was not related to binge eating or overeating. Our findings raise questions about prevailing models that posit restraint as a predominant factor in the maintenance of binge eating in BED.     

Gender Differences in Shame in Patients with Binge‐Eating Disorder

Objective: To examine the relationship between shame and the behavioral and attitudinal features of eating disorders in men and women diagnosed with binge‐eating disorder (BED). Research Methods and Procedures: Participants were 188 consecutively evaluated adults (38 men and 150 women) who met Diagnostic and Statistical Manual of Mental Disorders, 4th edition, criteria for BED. Participants were interviewed and completed a battery of measures assessing shame, behavioral and attitudinal features of eating disorders, and general psychological functioning. Results: Shame did not differ significantly by gender and was not associated with BMI or binge‐eating frequency. Shame was significantly associated with the attitudinal features of eating disorders, even after controlling for levels of depression and self‐esteem. When considered separately by gender and controlling for depression and self‐esteem, shame was associated with body dissatisfaction in men and with weight concern in women. Discussion: Men and women with BED, who presented for treatment, reported similar levels of shame. Overall, while shame was related to attitudinal features, the specific associations differed by gender. For men, shame was related to how dissatisfied they felt with their bodies, whereas for women, shame was associated with concerns about weight. Interestingly, shame was not related to BMI or binge‐eating frequency in men or women. These results provide preliminary support for self‐conscious emotions playing different roles in men and women with BED.     

Loss of control is central to psychological disturbance associated with binge eating disorder

Objective: Binge eating disorder (BED) is positively associated with obesity and psychological distress, yet the behavioral features of BED that drive these associations are largely unexplored. The primary aim of this study was to investigate which core behavioral features of binge eating are most strongly related to psychological disturbance. Methods and Procedures: A cross‐sectional study involved 180 bariatric surgery candidates, 93 members of a non‐surgical weight loss support group, and 158 general community respondents (81 men/350 women, mean age 45.8 ± 13.3, mean BMI 34.8 ± 10.8, BMI range 17.7–66.7). Validated questionnaires assessed BED and binge eating, symptoms of depression, appearance dissatisfaction (AD), quality of life (QoL) and eating‐related behaviors. Features of binge eating were confirmed by interview. BMI was determined by clinical assessment and self‐report. Results: The loss of control (LOC) over eating, that is, being unable to stop eating or control what or how much was consumed was most closely related to psychological markers of distress common in BED. In particular, those who experienced severe emotional disturbance due to feelings of LOC reported higher symptoms of depression (P < 0.001), AD (P = 0.009), and poorer mental health–related QoL (P = 0.027). Discussion: Persons who report subjective binge episodes or do not meet BED frequency criteria for objective binge episodes may still be at elevated risk of psychological disturbance and benefit from clinical intervention. Feelings of LOC could drive binge eaters to seek bariatric surgery in an attempt to gain control over body weight and psychologically disturbing eating behavior.     

Appearance vs. Health Reasons for Seeking Treatment Among Obese Patients with Binge Eating Disorder

Objectives : This study examined reasons for seeking treatment reported by obese patients diagnosed with binge eating disorder (BED). Research Methods and Procedures : Participants were 248 adults (58 men and 190 women) who met DSM criteria for BED. Participants were recruited through advertisements for treatment studies looking for persons who wanted to “stop binge eating and lose weight.” Patients’ reasons for seeking treatment were examined with respect to demography (gender and age), obesity (BMI and age of onset), features of eating disorders, and associated psychological functioning (depression and self‐esteem). Results : Of the 248 participants, 64% reported health concerns and 36% reported appearance concerns as their primary reason for seeking treatment. Reasons for seeking treatment did not differ significantly by gender. Patients seeking treatment because of appearance‐related reasons had lower BMIs than those reporting health‐related reasons (34.8 vs. 38.5, respectively), but they reported greater body dissatisfaction, more features of eating disorders, and lower self‐esteem. Discussion : Reasons that prompt treatment seeking among obese individuals with BED reflect meaningful patient characteristics and, therefore, warrant assessment and consideration during treatment planning. Further research is needed to determine whether reasons for treatment seeking among different obese patient groups affect treatment outcomes.     

Self-Efficacy in Overweight Individuals with Binge Eating Disorder

MILLER, PETER M., JULIA A. WATKINS, ROGER G. SARGENT, AND EDWARD J. RICKERT. Self-efficacy in overweight individuals with binge eating disorder. Obes Res. Objective: To evaluate the relationship between self-efficacy judgments in obese individuals with binge eating disorder, “borderline” binge eating disorder, and no binge eating problems. Research Methods and Procedures: Before participation in a residential weight management program, 79 male and female subjects were administered the Weight Efficacy Lifestyle Questionnaire (WEL) and the Binge Eating Scale (BES). Based on DSM-IV diagnostic questions, subjects were categorized as BED, Borderline BED, or non-BED. Results: Krusal-Wallace Rank-Order analysis of variance revealed significant negative associations between binge eating and total WEL scores as well as the subscales of Negative Emotions, Social Pressure, Physical Discomfort, and Positive Activities. Differences were significant between the BED and the Borderline BED groups with the exception of the Social Pressure scale and the Total WEL scores. BED diagnosis as well as severity of binge eating were strongly associated with low self-efficacy ratings. Discussion: These results indicate that obese individuals with binge eating disorder demonstrate lower self-efficacy than those without this condition and that self-efficacy is related to the severity of binge eating.     

The Association between Maltreatment in Childhood and Pre-Pregnancy Obesity in Women Attending an Antenatal Clinic in Australia

Introduction

Obesity in pregnancy is associated with increased risk of complications and adverse outcomes in mother and child. Childhood adverse experiences are known to have numerous negative physical and emotional sequelae. We aimed to examine if exposure to abuse and/or neglect in childhood increased the likelihood of pre-pregnancy obesity.

Methods

Demographic and clinical data including weight, height, mental health as measured by the General Health Questionnaire and exposure to childhood trauma as measured by the childhood trauma questionnaire was collected from 239 women attending antenatal care at an Australian tertiary hospital.

Results

More than one quarter of women were obese prior to pregnancy and approximately 20% of women self reported experiencing moderate to severe physical, sexual or emotional abuse. Almost 60% of women scored in the clinical range on the GHQ. Pre-pregnancy obesity in women attending antenatal care was associated with a self-reported history of emotional or physical abuse with those exposed to moderate or severe emotional or physical abuse having increased odds of being obese prior to pregnancy (O.R. and 95% CI: 2.40; 1.19–4.84 and 2.38; 1.18–4.79 respectively). There was no significant association between other forms of childhood maltreatment, demographic or current mental health status and pre-pregnancy obesity.

Conclusions

The high rates of obesity, mental health problems and self reported childhood maltreatment in the Australian antenatal population are serious public health concerns due to the extra health risks conferred on mother and offspring. Exposure to physical or emotional abuse during childhood increases the likelihood of obesity in women attending antenatal care. Further research is required to determine reasons for this association.     

A 30‐year Follow‐up of the Effects of Child Abuse and Neglect on Obesity in Adulthood

Childhood maltreatment has been implicated as a risk factor for adult obesity. We describe the first prospective assessment of adult obesity in individuals with documented histories of childhood physical and sexual abuse and neglect and a matched comparison group in a 30‐year follow‐up. Using a prospective cohort design, children with court substantiated cases of physical and sexual abuse and neglect (ages 0–11 years) from a Midwest county during 1967–1971 (n = 410) were matched with children without histories of abuse or neglect on age, sex, race/ethnicity and approximate family social class (n = 303) and followed up and assessed at mean age 41. Outcome measures include BMI and obesity assessed in 2003–2004 as part of a medical status examination and interview. Childhood physical abuse predicted significantly higher BMI scores in adulthood (β = 0.14, P < 0.05), even controlling for demographic characteristics, cigarette smoking, and alcohol consumption (β = 0.16, P < 0.01). Childhood sexual abuse (β = 0.07, not significant) and neglect (β = 0.02, not significant) were not significant predictors of adult BMI scores. These results demonstrate the long‐term impact of childhood physical abuse on weight into adulthood and suggest that physically abused children may be at risk for other adverse health outcomes associated with increased weight. Health professionals need to understand this risk for physically abused children and researchers should identify and evaluate strategies for effective interventions.     

Accuracy of Self‐reported Weight and Height in Binge Eating Disorder: Misreport Is Not Related to Psychological Factors

This study examined the degree of misreport in weight, height, and BMI among overweight adults (n = 392) with binge eating disorder (BED) and tested whether the degree of misreport was associated with eating disorder psychopathology and psychological variables. Male (n = 97) and female (n = 295) participants self‐reported height and weight, and were subsequently measured by clinic staff. Participants also completed a series of diagnostic interviews and self‐report assessments. Discrepancies between self‐reported and measured values were modest. The degree of misreport for weight, height, and BMI was not related to eating disorder features, depression, and self‐esteem. Overall, the errors in self‐reported weight and height by overweight patients with BED were very slight. The degree of discrepancy between self‐reported and measured values was not related to eating disorder or psychological features, suggesting that such data are not biased or systematically related to individual differences in overweight patients with BED.     

Differences in Body Image and Depression Among Obese Women With and Without Binge Eating Disorder

Obese individuals with binge eating disorder (BED) differ from obese non-binge eating (NBE) individuals in a number of clinically relevant ways. This study examined attitudinal responses to various measures of body image in women seeking obesity treatment, by comparing NBE participants (n=80) to those with BED (n=48). It was hypothesized that women with BED would demonstrate greater attitudinal disturbance of body image compared to NBE individuals. It was further hypothesized that significant differences between groups would remain after statistically controlling for degree of depression. Consistent with the primary hypothesis, BED participants reported significantly increased attitudinal disturbance in body dissatisfaction and size perception compared to NBE participants. Although shared variance was observed between measures of depression and body image on some items, several aspects of increased body image disturbance remained after statistically controlling for depression. Treatment implications and recommendations for future research are discussed.     

The Long-Term Health Consequences of Child Physical Abuse,Emotional Abuse,and Neglect: A Systematic Review and Meta-Analysis

Background

Child sexual abuse is considered a modifiable risk factor for mental disorders across the life course. However the long-term consequences of other forms of child maltreatment have not yet been systematically examined. The aim of this study was to summarise the evidence relating to the possible relationship between child physical abuse, emotional abuse, and neglect, and subsequent mental and physical health outcomes.

Methods and Findings

A systematic review was conducted using the Medline, EMBASE, and PsycINFO electronic databases up to 26 June 2012. Published cohort, cross-sectional, and case-control studies that examined non-sexual child maltreatment as a risk factor for loss of health were included. All meta-analyses were based on quality-effects models. Out of 285 articles assessed for eligibility, 124 studies satisfied the pre-determined inclusion criteria for meta-analysis. Statistically significant associations were observed between physical abuse, emotional abuse, and neglect and depressive disorders (physical abuse [odds ratio (OR) = 1.54; 95% CI 1.16–2.04], emotional abuse [OR = 3.06; 95% CI 2.43–3.85], and neglect [OR = 2.11; 95% CI 1.61–2.77]); drug use (physical abuse [OR = 1.92; 95% CI 1.67–2.20], emotional abuse [OR = 1.41; 95% CI 1.11–1.79], and neglect [OR = 1.36; 95% CI 1.21–1.54]); suicide attempts (physical abuse [OR = 3.40; 95% CI 2.17–5.32], emotional abuse [OR = 3.37; 95% CI 2.44–4.67], and neglect [OR = 1.95; 95% CI 1.13–3.37]); and sexually transmitted infections and risky sexual behaviour (physical abuse [OR = 1.78; 95% CI 1.50–2.10], emotional abuse [OR = 1.75; 95% CI 1.49–2.04], and neglect [OR = 1.57; 95% CI 1.39–1.78]). Evidence for causality was assessed using Bradford Hill criteria. While suggestive evidence exists for a relationship between maltreatment and chronic diseases and lifestyle risk factors, more research is required to confirm these relationships.

Conclusions

This overview of the evidence suggests a causal relationship between non-sexual child maltreatment and a range of mental disorders, drug use, suicide attempts, sexually transmitted infections, and risky sexual behaviour. All forms of child maltreatment should be considered important risks to health with a sizeable impact on major contributors to the burden of disease in all parts of the world. The awareness of the serious long-term consequences of child maltreatment should encourage better identification of those at risk and the development of effective interventions to protect children from violence.

Treatment outcome in people with subthreshold compared with full-syndrome binge eating disorder

Objective: There is a controversial discussion in the literature as to whether individuals with subthreshold binge eating disorder (subBED) differ clinically significantly from individuals with full‐syndrome binge eating disorder (BED). This study was designed to compare eating‐related and general psychopathology at baseline and in response to a multimodal treatment program in obese people with subBED compared with BED. Research Methods and Procedures: A total of 96 obese participants (BMI ≥ 30 kg/m²) were assessed for eating‐related and general psychopathology at baseline. Thirty‐nine participants meeting criteria for BED and 19 participants meeting criteria for subBED attended a 15‐session outpatient group therapy including cognitive behavioral therapy extended by interpersonal therapy, nutritional counseling, and a supervised walking exercise. Participants with eating disorders were reassessed at the end of treatment and at 3‐month follow‐up. The obese control group without an eating disorder (n = 38) was assessed once. This was not a randomized controlled trial. Results: Intent‐to‐treat analyses revealed no differences between subBED and full‐syndrome BED participants with regard to eating‐related and general psychopathology at baseline and with regard to treatment outcome. All participants experienced substantial improvements, and the results remained stable during follow‐up (except for dietary restraint). At follow‐up, participants with subBED and BED remained different from non‐eating disorder controls in eating‐related but not general psychopathology. Discussion: The findings indicate that our multimodal treatment program is equally effective in obese subBED and BED participants, suggesting that a differentiation currently seems not to be of clinical significance.     

Binge Size Increases with Body Mass Index in Women with Binge-Eating Disorder

Objective: To determine whether meal size is related to body mass index (BMI) in obese subjects with binge-eating disorder (BED). Research Methods and Procedures: Five groups of subjects each consumed two laboratory-test meals on nonconsecutive days. Forty-two women, categorized by BMI and BED diagnosis, were instructed to “binge” during one meal and to eat “normally” during another. Eighteen women had BMI values >38 kg/m² (more-obese) and 17 had BMI values between 28 to 32 kg/m² (less-obese). Twelve of the more-obese and nine of the less-obese individuals met Diagnostic and Statistical Manual (DSM)-IV criteria for BED. Seven normal-weight women also participated as controls. Results: Subjects with BED ate significantly more in both meals than subjects without BED. Binge meals were significantly larger than normal meals only among subjects with BED. The more-obese subjects with BED ate significantly more than the less-obese subjects with BED, but only when they were asked to binge. Intake of the binge meal was significantly, positively correlated with BMI among subjects with BED. Subjects with BED reported significantly higher satiety ratings after the binge than after the normal meal, but subjects without BED reported similar ratings after both meals. Regardless of instructions and diagnosis, obese subjects consumed a significantly higher percentage of energy from fat (38.5%) than did normal-weight subjects (30.8%). Discussion: During binge meals, the energy intake of subjects with BED is greater than that of individuals of similar body weight without BED and is positively correlated with BMI.     

Binge-Eating Disorder in Brazilian Women on a Weight-Loss Program

Objective: To examine binge-eating disorder (BED) and its association with obesity, weight patterns, and psychopathology in a Brazilian sample of female participants of a weight-loss program in São Paulo, Brazil. Research Methods and Procedures: Two hundred and seventeen overweight (body mass index ≥ 25 kg/m²) women, ages 15 to 59 years, enrolled in the Weight Watchers Program were recruited for the study at a program branch meeting after completing the Questionnaire on Eating and Weight Patterns–Revised, Beck Depression Inventory, and the Toronto Alexithymia Scale-20. Participants were categorized into four groups: those who met questionnaire criteria for BED, those who met questionnaire criteria for bulimia nervosa (BN), those that reported binge eating but did not meet all the criteria for any eating disorder (BE), and those with no eating disorder symptoms (No ED). Groups were compared on measures of weight, depressive symptoms, and alexithymia. Results: Binge eating was frequently reported by women in this study (BED, 16.1%; BN, 4.6%; BE, 22.6%). BED women had significantly higher body mass index, greater highest weight ever, and more frequent weight cycling than the No ED group. BED women also reported more depressive symptoms than BE and No ED women, and were more alexithymic than the No ED group. BE women presented more frequent weigh cycling and were also more depressed and alexithymic than the No ED group. Discussion: BED is not uncommon in overweight Brazilian women, and similar to North American and European samples, it is associated with overweight and higher levels of psychopathology in this population.     

Emotional Eating,Alexithymia, and Binge‐Eating Disorder in Obese Women

Objective: To investigate the relationships between alexithymia and emotional eating in obese women with or without Binge Eating Disorder (BED). Research Methods and Procedures: One hundred sixty‐nine obese women completed self‐report questionnaires, including the Beck Depression Inventory, the State Trait Anxiety Inventory, the Stress Perceived Scale, the Dutch Eating Behaviour Questionnaire, and the Toronto Alexithymia Scale. The presence of BED, screened using the Questionnaire of Eating and Weight Patterns, was confirmed by interview. Results: Forty obese women were identified as having BED. BED subjects and non‐BED subjects were comparable in age, body mass index, educational level, and socioeconomic class. According to the Dutch Eating Behaviour Questionnaire, BED subjects exhibited higher depression, anxiety, perceived stress, alexithymia scores, and emotional and external eating scores than non‐BED subjects. Emotional eating and perceived stress emerged as significant predictors of BED. The relationships between alexithymia and emotional eating in obese subjects differed between the two groups according to the presence of BED. Alexithymia was the predictor of emotional eating in BED subjects, whereas perceived stress and depression were the predictors in non‐BED subjects. Discussion: This study pointed out different relationships among mood, alexithymia, and emotional eating in obese subjects with or without BED. Alexithymia was linked to emotional eating in BED. These data suggest the involvement of alexithymia in eating disorders among obese women.     

A Systematic Review of Childhood Maltreatment Assessments in Population-Representative Surveys Since 1990

BackgroundPopulation-representative surveys that assess childhood maltreatment and health are a valuable resource to explore the implications of child maltreatment for population health. Systematic identification and evaluation of such surveys is needed to facilitate optimal use of their data and to inform future research.ObjectivesTo inform researchers of the existence and nature of population-representative surveys relevant to understanding links between childhood maltreatment and health; to evaluate the assessment of childhood maltreatment in this body of work.MethodsWe included surveys that: 1) were representative of the non-institutionalized population of any size nation or of any geopolitical region ≥ 10 million people; 2) included a broad age range (≥ 40 years); 3) measured health; 4) assessed childhood maltreatment retrospectively; and 5) were conducted since 1990. We used Internet and database searching (including CINAHL, Embase, ERIC, Global Health, MEDLINE, PsycINFO, Scopus, Social Policy and Practice: January 1990 to March 2014), expert consultation, and other means to identify surveys and associated documentation. Translations of non-English survey content were verified by fluent readers of survey languages. We developed checklists to abstract and evaluate childhood maltreatment content.ResultsFifty-four surveys from 39 countries met inclusion criteria. Sample sizes ranged from 1,287-51,945 and response rates from 15%-96%. Thirteen surveys assessed neglect, 15 emotional abuse; 18 exposure to family violence; 26 physical abuse; 48 sexual abuse. Fourteen surveys assessed more than three types; six of these were conducted since 2010. In nine surveys childhood maltreatment assessments were detailed (+10 items for at least one type of maltreatment). Seven surveys’ assessments had known reliability and/or validity.

Conclusions and Implications

Data from 54 surveys can be used to explore the population health relevance of child maltreatment. Assessment of childhood maltreatment is not comprehensive but there is evidence of recent improvement.     

Childhood Maltreatment and BMI Trajectories to Mid-Adult Life: Follow-Up to Age 50y in a British Birth Cohort

Background

Childhood maltreatment including abuse and neglect has been associated with adult obesity, but evidence on life-course development of obesity or BMI gain is unclear. We aim to establish whether childhood maltreatments are related to obesity or BMI at different life-stages 7y-50y and to identify possible explanations for associations.

Methods

Childhood physical, psychological and sexual abuse, neglect and BMI at seven ages were recorded in the 1958 birth cohort (n~15,000). Associations of child maltreatments with BMI at separate ages were tested using linear regression or logistic regression for obesity, and with rate of child-to-adult BMI gain using multilevel models. We adjusted for potential covariates.

Results

Abuse was reported in ~12% of the population. Abuse was not associated with elevated childhood BMI, but adult associations were observed: i.e. the abused had faster child-adult BMI gain than the non-abused; associations were independent of adult covariates. For physical abuse in both genders there was a positive linear association of ~0.006/y zBMI gain with age after adjustment for all covariates. Similarly, there was a linear association of physical abuse with obesity risk: e.g. among females from a low OR_adjusted of 0.34 (0.16,0.71) at 7y to 1.67 (1.25,2.24) at 50y. In females faster zBMI gains with age of ~0.0034/y were observed for sexual abuse and increases in obesity risk were faster: from a low OR_adjusted of 0.23 (0.06,0.84) at 7y to 1.34 (0.86,2.10) at 50y. Psychological abuse and neglect associations were less consistent.

Conclusions

Childhood maltreatment associations with BMI or obesity varied across life: physical and, in females, sexual abuse were associated with faster lifetime BMI gains, which may have detrimental long-term health consequences.     

Energy Intake Patterns in Obese Women with Binge Eating Disorder

Objective: For binge eating disorder (BED) to be accepted as a distinct diagnostic category in the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition, it must be demonstrated that the criteria identify a diagnostic entity that is distinct from bulimia nervosa and obesity. This study examined the difference in total energy intake per day, patterns of energy intake throughout the day, and nutrient content of foods consumed in obese individuals who met the criteria for BED (on binge and non‐binge days) and those who did not. Research Methods and Procedures: Twenty women, 12 who met Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition, criteria for BED and 8 matched obese controls, participated in the study. All participants underwent six random 24‐hour dietary recall telephone interviews conducted by experienced interviewers using the Nutrition Data Software System. Results: The BED group ingested significantly more kilocalories on days when they had binge eating episodes than the obese control group on average. The BED group ate significantly more in the evening on binge days than their control group counterparts. There is some indication in the data that those with BED may be restricting caloric intake. Finally, data indicated that the BED group ate significantly more protein, carbohydrate, and fat on binge days than on non‐binge days. However, the proportion of kilocalories from each nutrient shifted on BED binge days compared with non‐binge days to favor consumption of fat over carbohydrates. Discussion: More research needs to be done to determine if these findings are reproducible. Then, the neurobiological underpinnings of these differences in nutrient intake patterns and nutrient selection can be studied to help to determine the biological basis of the disorder.     

Association of major depression and binge eating disorder with weight loss in a clinical setting

Objective: Obesity has been linked to both major depressive disorder (MDD) and binge eating disorder (BED) in clinical and epidemiological studies. The present study compared weight loss among patients with and without MDD and BED who participated in a hospital‐based weight loss program modeled after the Diabetes Prevention Program. Research Methods and Procedures: Of 131 obese patients who enrolled in treatment, 17% were diagnosed with MDD only, 13% were diagnosed with BED only, 17% were diagnosed with both MDD and BED, and 53% lacked either diagnosis in a pretreatment clinical interview. Results: After treatment, patients with MDD only attained 63% of the weight loss that non‐depressed patients attained. Patients with BED only attained 55% of the weight loss that non‐binge eaters attained. The effect of MDD on weight loss was not accounted for by the presence of BED or vice versa. Only 27% of patients with both MDD and BED achieved clinically significant weight loss compared with 67% of patients who had neither disorder. Results were not significantly altered when gender, age, and diabetes status were adjusted. Conclusion: Both MDD and BED were prevalent among this obese clinical population, and each disorder was independently associated with worse outcomes. Research is needed to investigate how to increase the efficacy of behavioral weight loss programs for individuals with MDD and/or BED.
