The effect of obesity management on body image in patients seeking treatment at medical centers

Dropout in cognitive behavioral treatment in adults living with overweight and obesity: a systematic review

Obesity is a chronic, complex, and multifactorial disease resulting from the interaction of genetic, environmental, and behavioral factors. It is characterized by excessive fat accumulation in adipose tissue, which damages health and deteriorates the quality of life. Although dietary treatment can significantly improve health, high attrition is a common problem in weight loss interventions with serious consequences for weight loss management and frustration. The strategy used to improve compliance has been combining dietary prescriptions and recommendations for physical activity with cognitive behavioral treatment (CBT) for weight management. This systematic review determined the dropout rate and predictive factors associated with dropout from CBT for adults with overweight and obesity. The data from the 37 articles selected shows an overall dropout rate between 5 and 62%. The predictive factors associated with attrition can be distinguished by demographics (younger age, educational status, unemployed status, and ethnicity) and psychological variables (greater expected 1-year Body Mass Index loss, previous weight loss attempts, perceiving more stress with dieting, weight and shape concerns, body image dissatisfaction, higher stress, anxiety, and depression). Common reasons for dropping out were objective (i.e., long-term sickness, acute illness, and pregnancy), logistical, poor job conditions or job difficulties, low level of organization, dissatisfaction with the initial results, lack of motivation, and lack of adherence. According to the Mixed Methods Appraisal quality analysis, 13.5% of articles were classified as five stars, and none received the lowest quality grade (1 star). The majority of articles were classified as 4 stars (46%). At least 50% of the selected articles exhibited a high risk of bias. The domain characterized by a higher level of bias was that of randomization, with more than 60% of the articles having a high risk of bias. The high risk of bias in these articles can probably depend on the type of study design, which, in most cases, was observational and non-randomized. These findings demonstrate that CBT could be a promising approach for obesity treatment, achieving, in most cases, lower dropout rates than other non-behavioral interventions. However, more studies should be conducted to compare obesity treatment strategies, as there is heterogeneity in the dropout assessment and the population studied. Ultimately, gaining a deeper understanding of the comparative effectiveness of these treatment strategies is of great value to patients, clinicians, and healthcare policymakers.

Weight Bias Internalization and Eating Disorder Psychopathology in Treatment-Seeking Patients with Obesity

This study aimed to investigate the relationship between weight bias internalization and eating disorder psychopathology in treatment-seeking patients with severe obesity using a network approach. Two thousand one hundred and thirteen patients with obesity were consecutively admitted to a specialist clinical unit for obesity and were recruited from January 2016 to February 2023. Body mass index was measured, and each patient completed the Weight Bias Internalization Scale (WBSI) and the Eating Disorder Examination Interview (EDE). Network analysis showed that the most central and highly interconnected nodes in the network were related to the EDE items exposure avoidance, dissatisfaction with shape, and wanting an empty stomach. Bridge nodes were found, but the bootstrap difference test on expected bridge influence indicated non-significant centrality differences. Nevertheless, the eating disorder psychopathology and weight bias internalization network structure in patients seeking treatment for obesity indicate the prominent roles of body dissatisfaction and control of eating and weight in these psychological constructs. This finding, if replicated, could pave the way for a new understanding of the psychological mechanisms operating in patients with obesity.

Cardiometabolic risk is unraveled by color Doppler ultrasound of the clitoral and uterine arteries in women consulting for sexual symptoms

Female sexual dysfunction (FSD) may be a mirror of a poor cardiometabolic state. In a small pilot study enrolling 71 women with FSD, we previously demonstrated that clitoral Pulsatility Index (PI) evaluated by using color Doppler ultrasound (CDU), reflecting vascular resistance, was associated with cardiometabolic risk factors. Data on uterine CDU in this context are lacking. First, to confirm previously reported data on the direct association between clitoral PI and cardiometabolic risk factors on a larger study population of women consulting for sexual symptoms; second, to investigate eventual similar correlations between cardiometabolic risk factors and CDU parameters of the uterine artery. We also ascertained whether uterine artery PI, similarly to what had previously been observed for clitoral artery PI, was directly related to body image uneasiness and psychopathological symptoms, assessed by validated questionnaires. N = 230 women consulting our clinic for sexual symptoms were examined with clitoral CDU and blood sampling and were asked to fill out the Female Sexual Function Index, the Middlesex Hospital Questionnaire (MHQ) and the Body Uneasiness Test (BUT). In a subgroup of women (n = 164), we also performed transvaginal CDU with measurement of uterine artery parameters. At multivariate analysis, we found a direct association between clitoral PI and body mass index (BMI) (p = 0.004), waist circumference (WC) (p = 0.004), triglycerides (p = 0.006), insulin (p = 0.029) and HOMA-IR (p = 0.009). Furthermore, a correlation between obesity and Metabolic Syndrome (MetS) and a higher clitoral PI was observed (p = 0.003 and p = 0.012, respectively). Clitoral PI was also correlated with MHQ-S (p = 0.010), a scale exploring somatized anxiety symptoms, and BUT-B Positive Symptom Distress Index (p = 0.010), a measure of body image concerns. Similarly, when investigating the uterine artery, we were able to demonstrate an association between its PI and BMI (p < 0.0001), WC (p = 0.001), insulin (p = 0.006), glycated haemoglobin (p =  < 0.0001), and HOMA-IR (p = 0.009). Women diagnosed with obesity and MetS showed significantly higher uterine PI values vs. those without obesity or MetS (p = 0.001 and p = 0.004, respectively). Finally, uterine PI was associated with BUT-A Global Severity Index (p < 0.0001) and with several other BUT-A subdomains. Vascular resistance of clitoral and uterine arteries is associated with cardiometabolic risk factors and body image concerns in women consulting for sexual symptoms. If further confirmed in different populations, our data could suggest CDU, a common examination method, as a useful tool for an identification—and possible correction—of cardiometabolic risk factors.

The Symptom-Checklist-K-9 (SCL-K-9) Discriminates between Overweight/Obese Patients with and without Significant Binge Eating Pathology: Psychometric Properties of an Italian Version

A general personality and psychopathology evaluation is considered to be crucial part of the multidisciplinary assessment for weight-related problems. The Symptom Checklist-90-Revised (SCL-90-R) is commonly used to assess general psychopathology in both overweight and obese patients seeking weight-loss treatment. The main purpose of the present research was to investigate the psychometric properties of the brief form of the SCL-90-R (i.e., the SCL-K-9) in a clinical sample (N = 397) of patients seeking weight-loss treatment (i.e., bariatric surgery and a nutritional weight-loss program). The results of the confirmatory factor analysis supported a one-factor solution of the SCL-K-9, with all nine items loading significantly on the common latent factor (lambdas ≥ 0.587). The ordinal α (= 0.91), the inter-item mean indices of correlation (rii = 0.53), and the convergent validity were also satisfactory. A receiver operating characteristic curves procedure showed that both SCL-90-R and SCL-K-9 were able to classify patients with and without significant binge eating pathology according to the Binge Eating Scale (BES) total score. Overall, our results suggest that the SCL-K-9 has adequate psychometric properties and can be applied as a short screening tool to assess general psychopathology in overweight/obese individuals seeking weight-loss treatment and at follow-up interviews when time restraints preclude the use of the full-length form.

The Real Happy Study: Protocol for a Prospective Assessment of the Real-World Effectiveness of the HAPIFED Program-a Healthy APproach to weIght management and Food in Eating Disorders

The prevalence of obesity with comorbid binge eating behaviour is growing at a faster rate than that seen for either obesity or eating disorders as separate conditions. Approximately 6% of the population are affected and they potentially face a lifetime of poor physical and mental health outcomes and an inability to sustain long-term weight loss. Current treatment options are inadequate in that they typically address either obesity or eating disorders exclusively, not the combination of both conditions. By treating one condition without treating the other, relapse is common, and patients are often left disappointed with their lack of weight loss. An integrated approach to treating these individuals is needed to prevent a worsening of the comorbidities associated with excess body weight and eating disorders. A new therapy has recently been developed, named HAPIFED, which addresses both overweight/obesity and comorbid binge eating behaviour with the combination of behavioural weight loss therapy and cognitive behaviour therapy-enhanced (CBT-E). The aim of this paper is to document the protocol for the Real Happy Study, which will evaluate the effectiveness of the HAPIFED program in treating overweight or obesity with comorbid binge-eating behaviour in a real-world setting.

Perceived Stress Mediates the Relationship of Body Image and Depressive Symptoms in Individuals With Obesity

Obesity is a world-wide increasing condition classified by a BMI ≥ 30 kg/m² that is frequently accompanied by various somatic comorbidities as well as an increased risk for mental comorbidities. Studies show associations of obesity with symptoms of depression, lower quality of life, and higher (perceived) stress compared to the general population. Body image has also been shown to play an important role in eating and weight disorders. The present study therefore aims to contribute to the understanding of the relationship of body image, perceived stress, and symptoms of depression in a morbidly obese population. N = 579 individuals with obesity were included upon presentation at a university clinic. The hypothesized mediating role of perceived stress in the relationship of body image dimensions and symptoms of depression could be confirmed. The results underline the importance of identifying promising stress management techniques and addressing perceived stress e.g. through mindfulness based approaches in the (lifestyle and/or weight) interventions for obesity taking into account the specific stressors of obesity affected individuals such as body image.

QUALITY OF LIFE AFTER VERTICAL GASTRECTOMY EVALUATED BY THE BAROS QUESTIONNAIRE

BACKGROUND

The satisfactory outcome in the surgical treatment of obesity must include, in addition to weight loss, a significant change in the pre-existing comorbidities and in the quality of life of the patients.

AIM

To evaluate the quality of life in the late postoperative period in patients that underwent videolaparoscopic sleeve gastrectomy.

METHODS

Was applied the questionnaire "Bariatric Analysis and Reporting Outcome System" (BAROS) in patients that underwent videolaparoscopic sleeve gastrectomy.

RESULTS

A total of 47 patients between 21-60 years old were evaluated. The total mean of the BMI before surgery was 43.06±5.87 kg/m². The average percentage of the reduction of excess weight after surgery was 85.46±23.6%. The score obtained by patients in the questionnaire about the improvement in the quality of life showed excellent (36.17%), very good (40.43%), good (21.28%) and reasonable (2.13%) results. There was clinical improvement after surgery in all comorbidities investigated.

CONCLUSION

BAROS showed excellent results in 36.17%, very good in 40.43%, good in 21.28% and reasonable in 2.13%. The weight loss was critical to improve the quality of life and offered the resolution or clinical improvement in all of the investigated comorbidities.

Long-term treatment of severe obesity: are lifestyle interventions still an option?

Following lifestyle intervention programs based on dietary restriction and habitual physical activity, weight loss, however large, is reported to peak within six months. Despite maintenance protocols, only few cases continue to lose weight thereafter. The majority of cases regain weight and adherence to lifestyle changes are fostered by long-term contact with a supportive team. In general, surgical procedures are reported to produce much larger weight loss and to impact more favorably on long-term weight loss maintenance. Areas covered: We performed a PubMed search on lifestyle modification studies, focusing on the role of behavior programs for the long-term management of obesity in comparison with surgical procedures. Behaviorally-achieved weight loss outcomes can be improved by integrating standard behavior therapy with self-regulation cognitive skills, motivational interviewing and/or phone/internet-based recall systems. Expert commentary: Clinically-important long-term weight loss is achievable by behavior therapy in a small proportion of subjects with obesity, however severe, through personalized programs associating lifestyle modification interventions, with procedures aimed at developing commitment and responsibility skills. A new area of research is the integration of cognitive-behavior therapy with bariatric (metabolic) surgery, either pre- or post-operatively, to exploit long-term adherence to healthy diet and habitual physical activity.

The relationship between emotional regulation and eating behaviour: a multidimensional analysis of obesity psychopathology

PURPOSE

The aim of this study is to show that the differences among eating behaviours are related to the emotional dysregulation connected to the mental dimensions being part of the obese psychopathology. Eating behaviours can be considered a diagnostic feature at the initial screening for determining the obesity treatment: nutritional or bariatric surgery.

METHODS

1828 Obese subjects underwent psychiatric assessment before entering obesity nutritional treatment or bariatric surgery following the multidisciplinary programme. 1121 subjects were selected and enrolled in this study: 850 were inpatients visited or hospitalised at the Obesity Centre or at the Bariatric Surgery Units, 271 were outpatients visited at the Eating Disorder and Obesity Unit. Psychiatric examination was used to exclude psychiatric disorders and investigate eating behaviours distinguished on the basis of food intake rhythm in: gorging, snacking, grazing and binge. They are related to the mental dimensions: impulsiveness, body image, mood and anxiety, taking part in the emotional regulation system. Specific psychometric tools were used to investigate the different mental dimensions of the single eating behaviours and their differences. Statistical analysis of the psychopathological features was performed using ANOVA, ANCOVA, Levene test, Bonferroni's and Tamhane post hoc test. Significance was set at p < 0.05.

RESULTS

Data analysis shows significant differences of psychopathology among all the eating behaviours and an increase in the emotional dysregulation determining maladaptive behaviours.

DISCUSSION

Eating behaviours are connected to the balance of the different features of mental dimensions implicated in the emotional regulation system. They could provide significant clinical information and therefore be part of the obesity diagnostic criteria and therapeutic programme.

Conclusion

The weight loss was critical to improve the quality of life and offered the resolution or clinical improvement in all of the investigated comorbidities in patients submitted to sleeve gastrectomy.

Comparison of Efficacy and Safety of Liraglutide 3.0 mg in Individuals with BMI above and below 35 kg/m²: A Post-hoc Analysis

OBJECTIVE

To investigate whether the efficacy and safety of liraglutide 3.0 mg differed between two subgroups, BMI 27 to <35 and BMI ≥ 35 kg/m², in individuals without and with type 2 diabetes (T2D).

METHODS

A post-hoc analysis of two 56-week, randomized, double-blind, placebo-controlled trials (SCALE Obesity and Prediabetes; SCALE Diabetes). Subgroup differences in treatment effects of liraglutide 3.0 mg were evaluated by testing the interaction between treatment group and baseline BMI subgroup.

RESULTS

Significantly greater weight loss (0-56 weeks) was observed with liraglutide 3.0 mg versus placebo in all patient groups while on treatment. There was no evidence that the weight-lowering effect of liraglutide 3.0 mg differed between BMI subgroups (interaction p > 0.05). Similarly, for most secondary endpoints significantly greater improvements were observed with liraglutide 3.0 mg versus placebo, with no indication treatment effects differing between subgroups. The safety profile of liraglutide 3.0 mg was broadly similar across BMI subgroups.

CONCLUSION

This post-hoc analysis did not indicate any differences in the treatment effects, or safety profile, of liraglutide 3.0 mg for individuals with BMI 27 to <35 or ≥35 kg/m². Liraglutide 3.0 mg can therefore be considered for individuals with a BMI of ≥35 as well as for those with a BMI of 27 to <35 kg/m².

Long-term weight loss maintenance for obesity: a multidisciplinary approach

The long-term weight management of obesity remains a very difficult task, associated with a high risk of failure and weight regain. However, many people report that they have successfully managed weight loss maintenance in the long term. Several factors have been associated with better weight loss maintenance in long-term observational and randomized studies. A few pertain to the behavioral area (eg, high levels of physical activity, eating a low-calorie, low-fat diet; frequent self-monitoring of weight), a few to the cognitive component (eg, reduced disinhibition, satisfaction with results achieved, confidence in being able to lose weight without professional help), and a few to personality traits (eg, low novelty seeking) and patient-therapist interaction. Trials based on the most recent protocols of lifestyle modification, with a prolonged extended treatment after the weight loss phase, have also shown promising long-term weight loss results. These data should stimulate the adoption of a lifestyle modification-based approach for the management of obesity, featuring a nonphysician lifestyle counselor (also called "lifestyle trainer" or "healthy lifestyle practitioner") as a pivotal component of the multidisciplinary team. The obesity physicians maintain a primary role in engaging patients, in team coordination and supervision, in managing the complications associated with obesity and, in selected cases, in the decision for drug treatment or bariatric surgery, as possible more intensive, add-on interventions to lifestyle treatment.

Effects of lifestyle interventions that include a physical activity component in class II and III obese individuals: a systematic review and meta-analysis

BACKGROUND

In class II and III obese individuals, lifestyle intervention is the first step to achieve weight loss and treat obesity-related comorbidities before considering bariatric surgery. A systematic review, meta-analysis, and meta-regression were performed to assess the impact of lifestyle interventions incorporating a physical activity (PA) component on health outcomes of class II and III obese individuals.

METHODS

An electronic search was conducted in 4 databases (Medline, Scopus, CINAHL and Sportdiscus). Two independent investigators selected original studies assessing the impact of lifestyle interventions with PA components on anthropometric parameters, cardiometabolic risk factors (fat mass, blood pressure, lipid and glucose metabolism), behaviour modification (PA and nutritional changes), and quality of life in adults with body mass index (BMI) ≥ 35 kg/m2. Estimates were pooled using a random-effect model (DerSimonian and Laird method). Heterogeneity between studies was assessed by the Cochran's chi-square test and quantified through an estimation of the I².

RESULTS

Of the 3,170 identified articles, 56 met our eligibility criteria, with a large majority of uncontrolled studies (80%). The meta-analysis based on uncontrolled studies showed significant heterogeneity among all included studies. The pooled mean difference in weight loss was 8.9 kg (95% CI, 10.2-7.7; p < 0.01) and 2.8 kg/m² in BMI loss (95% CI, 3.4-2.2; p < 0.01). Long-term interventions produced superior weight loss (11.3 kg) compared to short-term (7.2 kg) and intermediate-term (8.0 kg) interventions. A significant global effect of lifestyle intervention on fat mass, waist circumference, blood pressure, total cholesterol, LDL-C, triglycerides and fasting insulin was found (p<0.01), without significant effect on HDL-C and fasting blood glucose.

CONCLUSIONS

Lifestyle interventions incorporating a PA component can improve weight and various cardiometabolic risk factors in class II and III obese individuals. However, further high quality trials are needed to confirm this evidence, especially beyond weight loss.

Body image and breastfeeding practices in obese mothers

PURPOSE

This study analyzed body image perceptions and breastfeeding practices in obese mothers.

METHODS

Prospective, case-control study on 25 obese (BMI >30 kg/m(2)) and 25 normal-weight puerperae, matched for parity and delivery route. The participants completed the Body Uneasiness Test, a two-part, self-report questionnaire, investigating body image perception before they were discharged from hospital and participated in telephone interviews concerning breastfeeding practices.

RESULTS

Obese women demonstrated body image dissatisfaction related to their obesity. On average, they reported significantly higher scores on Global Severity Index (p < 0.0001) and on all of the BUT-A subscales: Weight Phobia (p < 0.02), Body Image Concerns (p < 0.0001), Avoidance (p < 0.0001), Compulsive Self-Monitoring (p < 0.01), and Depersonalization (p = 0.002) than did normal-weight puerperae. Moreover, they also had higher BUT-B scores and the Positive Symptom Total was significantly higher (p < 0.002). Finally, while breastfeeding practices at discharge were similar in the two groups, the obese mothers were more likely to maintain full breastfeeding at 6 months (p < 0.04).

CONCLUSIONS

Obese mothers have negative body image perceptions but they maintain full breastfeeding longer.

Treatment of the obese patient in primary care: targeting and meeting goals and expectations

Obesity is a serious disease associated with increased patient risk of several comorbidities, including type 2 diabetes mellitus, cardiovascular disease, dyslipidemia, hypertension, some cancers, and greater mortality. Furthermore, obesity has a deleterious impact on quality of life and increases health care costs. Moderate weight loss of 5% to 10% has been shown to significantly improve several patient cardiometabolic risk factors and physical functioning, however, it is often difficult to begin the weight-loss conversation with patients. Primary care providers play a critical role in discussing the health effects of excess weight with patients, managing obesity-related comorbidities, and recommending appropriate weight-loss strategies. Open communication, realistic goal setting, and consistent monitoring are key factors in implementing an effective weight-loss program in the primary care setting. Although diet and lifestyle modifications are the first lines of approach and the foundation of any weight-loss strategy, in many cases, additional interventions may be necessary, including medical or surgical management. Herein, we discuss the approaches that primary care providers should consider when recommending appropriate weight-loss strategies for overweight/obese patients to achieve clinically meaningful weight loss, including pharmacotherapies approved for chronic management of patients with obesity, to be used as adjuncts to diet and lifestyle modifications, and surgical options.

Lifestyle modification in the management of obesity: achievements and challenges

Lifestyle modification therapy for overweight and obese patients combines specific recommendations on diet and exercise with behavioral and cognitive procedures and strategies. In completers it produces a mean weight loss of 8-10 % in about 30 weeks of treatment. However, two main issues still to be resolved are how to improve dissemination of this approach, and how to help patients maintain the healthy behavioral changes and avoid weight gain in the long term. In recent years, several strategies for promoting and maintaining lifestyle modification have been evaluated, and promising results have been achieved by individualising the treatment, delivering the intervention by phone and internet or in a community setting, and combining lifestyle modification programs with residential treatment and bariatric surgery. These new strategies raise optimistic expectations for the effective management of obesity through lifestyle modification.

Emotionally focused group therapy and dietary counseling in binge eating disorder. Effect on eating disorder psychopathology and quality of life

OBJECTIVE

To test the effect on psychopathology and quality of life of Emotionally Focused Therapy (EFT), Dietary Counseling (DC), and Combined Treatment (CT) in treatment-seeking patients with Binge Eating Disorder (BED) and obesity.

METHODS

Utilizing an observational study design, 189 obese adult patients with BED were treated by manualized therapy protocols. An independent assessment of health-related quality of life (Obesity-Related Well-Being questionnaire - ORWELL-97), attitudes toward eating (Eating Inventory - EI), binge eating (Binge Eating Scale - BES) and body uneasiness (Body Uneasiness Test - BUT) was performed at baseline, end-of-treatment, and six-month follow-up. These data are the secondary outcomes of a previously published treatment study.

RESULTS

A higher dropout rate was observed in the DC compared to the EFT and CT groups, while body weight decreased significantly in all three groups. Pre-post scores on the BES, BUT Global Severity Index, and EI Hunger subscale significantly decreased in the CT and EFT groups (but not the DC group). At six-month follow-up, 71% of participants in CT and 46% of participants in EFT had a BES score below the threshold of attention for BED (≤16), whereas no participants in the DC group reached this target. Finally the ORWELL-97 score decreased significantly in all groups, but significantly more so in the CT and EFT groups.

CONCLUSION

Results support the utility of combining EFT and DC in the treatment of patients with BED and obesity, emphasizing the usefulness of techniques focused on cognitive emotional processing for changing eating disorder psychopathology and quality of life.

Major factors for facilitating change in behavioral strategies to reduce obesity

It is very unlikely that our obesity-promoting environment will change in the near future. It is therefore mandatory to improve our knowledge of the main factors associated with successful adoption of obesity-reducing behaviors. This may help design more powerful procedures and strategies to facilitate the adoption of healthy lifestyles in a "toxic" environment favoring the development of a positive energy balance. The aim of this review is to describe the main factors associated with successful adoption of obesity-reducing behaviors and to describe the most recent development, limits, and outcomes of lifestyle modification programs. The evidence regarding predictors of weight loss and weight loss maintenance remains largely incomplete. It is necessary to develop strategies matching treatments to patients' needs to improve successful weight loss and its maintenance. How to detect and how to address these needs is a continuous, challenging, research problem.

A randomized trial of energy-restricted high-protein versus high-carbohydrate, low-fat diet in morbid obesity

OBJECTIVE

Conflicting evidence exists as to weight loss produced by diets with different carbohydrate/protein ratio. The aim was to compare the long-term effects of high-protein vs. high-carbohydrate diet (HPD, HCD), combined with cognitive behavior therapy (CBT).

DESIGN AND METHODS

In a randomized trial, 88 obese participants (mean age, 46.7; mean BMI, 45.6 kg m(-2) ) were enrolled in a 3-week inpatient and 48-week outpatient treatment, with continuous CBT during the study period. All subjects consumed a restricted diet (1,200 kcal day(-1) for women, 1,500 for men; 20% energy from fat, <10% saturated fat). HPD derived 34% energy from proteins, 46% from carbohydrates; HCD 17% from proteins, 64% from carbohydrates. The primary outcome was 1-year percent weight loss. Secondary outcomes were attrition rates and changes in cardiovascular risk factors and psychological profile.

RESULTS

Attrition rates were similar between groups (25.6%). In the intention-to-treat analysis, weight loss averaged 15.0% in HPD and 13.3% in HCD at 1 year, without any difference throughout the study period. Both diets produced a similar improvement in secondary outcomes.

CONCLUSIONS

The relative carbohydrate and protein content of the diet, when combined with intensive CBT, does not significantly affect attrition rate, weight loss and psychosocial outcome in patients with severe obesity.

Weight loss and clinical characteristics of young adults patients seeking treatment at medical centers: data from the QUOVADIS Study

OBJECTIVE

To compare clinical characteristics, attrition, weight loss, and psychological changes of obese young adults and obese adults seeking treatment.

MATERIALS AND METHODS

1530 individuals seeking treatment in 18 Italian medical centers were evaluated. 382 cases (25%) were classified as young adults (age≤35 years), 1148 (75%) as adults (>35 years). Psychological distress, binge eating, body uneasiness, and attitude towards eating were evaluated, at baseline and after a 12-month weight-loss program, together with BMI changes. Weight-loss expectations and primary motivation for seeking treatment were also recorded.

RESULTS

At baseline, young adults reported significantly higher BMI at age 20, weight loss expectations and body uneasiness scores than adults. A significantly higher percentage of young adults also reported improving appearance as primary reason for seeking treatment. The attrition rate was significantly larger in young adults. Among completers, the mean percent weight loss at 12 months and improvement of psychosocial variables were significantly higher in young adults than in adults. By intention to treat, BMI changes were no longer significant between groups.

DISCUSSION

Obese young adults lose more weight and considerably improve psychological distress, but show a higher attrition rate after 12 months of continuous care in a real world medical setting.

Imagem corporal, ansiedade e depressão em pacientes obesos submetidos à cirurgia bariátrica

Pacientes obesos mórbidos têm recorrido à cirurgia bariátrica como um recurso eficaz para perder peso. Entretanto, este procedimento pode causar alterações comportamentais significativas. O objetivo deste trabalho foi investigar os níveis de ansiedade e depressão, assim como as mudanças sofridas na percepção da imagem corporal em pacientes obesos submetidos à cirurgia bariátrica em três momentos: pré-operatório, 6 meses e 12 meses após a cirurgia. Trata-se de um estudo do tipo prospectivo longitudinal, de abordagem quantitativa. No estudo foram aplicados os Inventários de Depressão e Ansiedade de Beck e a Escala Brasileira de Figuras de Silhuetas para Adultos. A cirurgia diminuiu significativamente tanto o índice de massa corporal dos pacientes quanto a insatisfação com a sua imagem corporal. Essa perda de peso e diminuição da insatisfação com a imagem corporal foi acompanhada de redução nos níveis de ansiedade e depressão, o que sugere que estes são fatores importantes no quadro obesidade.

Body image change and improved eating self-regulation in a weight management intervention in women

Background

Successful weight management involves the regulation of eating behavior. However, the specific mechanisms underlying its successful regulation remain unclear. This study examined one potential mechanism by testing a model in which improved body image mediated the effects of obesity treatment on eating self-regulation. Further, this study explored the role of different body image components.

Methods

Participants were 239 overweight women (age: 37.6 ± 7.1 yr; BMI: 31.5 ± 4.1 kg/m²) engaged in a 12-month behavioral weight management program, which included a body image module. Self-reported measures were used to assess evaluative and investment body image, and eating behavior. Measurements occurred at baseline and at 12 months. Baseline-residualized scores were calculated to report change in the dependent variables. The model was tested using partial least squares analysis.

Results

The model explained 18-44% of the variance in the dependent variables. Treatment significantly improved both body image components, particularly by decreasing its investment component (f² = .32 vs. f² = .22). Eating behavior was positively predicted by investment body image change (p < .001) and to a lesser extent by evaluative body image (p < .05). Treatment had significant effects on 12-month eating behavior change, which were fully mediated by investment and partially mediated by evaluative body image (effect ratios: .68 and .22, respectively).

Conclusions

Results suggest that improving body image, particularly by reducing its salience in one's personal life, might play a role in enhancing eating self-regulation during weight control. Accordingly, future weight loss interventions could benefit from proactively addressing body image-related issues as part of their protocols.

Awareness and knowledge about weight status and management: results from the 1 d sensitization campaign 'Obesity Day' in northern Italy

OBJECTIVE

To evaluate the awareness and knowledge about weight status and its management.

DESIGN

A 1 d cross-sectional survey. Basic anthropometric assessments (weight, height, BMI and waist circumference) and a self-administered questionnaire were considered.

SETTING

Nineteen Clinical Nutrition or Endocrinology and Metabolic Disorders Units or Dietetics Services in the Italian region of Lombardy.

SUBJECTS

All adults attending the 'Obesity Day' initiative.

RESULTS

A total of 914 participants (605 female and 309 male) were recruited. Although most of the participants (83·5 %) considered obesity to be a disease, 38·5 % were likely to misperceive their weight status. In particular, 38·8 % of normal-weight adults believed themselves to be overweight, whereas 71·1 % and 37·5 % of classes I and II/III obese adults classified themselves as being overweight and mildly obese, respectively. However, most of the overweight (90·2 %), mildly (96·8 %) and moderately/severely obese adults (99·1 %) recognized the need to lose weight. In all, 37·8 % of the sample underestimated the role of physical activity in weight management. Interestingly, only 17·2 % of dieters (previous or current) declared being advised by their doctor to lose weight. Multivariate models revealed that higher age, low education and higher BMI were important determinants of poor weight control and management. In addition, previous dieting appeared not to provide better knowledge, whereas the role of physical activity was recognized mainly by those practising it.

CONCLUSIONS

The present study suggests that in Italy knowledge about weight management should be improved not only in the general population but also among health-care professionals. To confirm this finding, there is now the rationale for a nationally representative survey. New educational programmes can be designed on the basis of the information collected.

Regular consumption of a cereal breakfast. Effects on mood and body image satisfaction in adult non-obese women

Breakfast has psychological and nutritional benefits due to physiological mechanisms and expectations about health impact. Beliefs people hold about calories in food can adversely affect mood and body-image satisfaction and such adverse reactions can be predicted by body mass index. The objectives were to test the effect of consuming isocaloric breakfasts, appearing different in calorie content, on appetite, mood and body-image satisfaction, and to assess impact on daily nutrient intake. One-hundred-and-twenty-three women were randomly assigned to eat a cereal or muffin breakfast which "appeared" different in calorie content while unaware they were isocaloric. Participants estimated calories of breakfast, appetite, mood, and body-image satisfaction on a daily basis for seven-days. The cereal breakfast was perceived to be lower in calories, made participants fuller, happier, relaxed, and more satisfied about weight and body compared to the muffin breakfast. Differences in estimated daily fibre and micronutrient intake were compatible with the design. Breakfasts were isocaloric yet the cereal breakfast was rated lower in calories and produced more positive psychological reactions. This evidence indicates the power of perceptions of foods to influence important attributes of health and well-being which could be valuable in dietary interventions where mood and body image satisfaction affect outcome.

Perceived calorie intake and state body-image satisfaction in women attempting weight loss: a preliminary investigation

State body-image satisfaction levels (BIS) can be predicted by appearance concerns, eating attitudes and body mass index (BMI). Determinants of state BIS and its variability were examined in women attempting weight loss. Little is known about contextual cues that influence state BIS; therefore the effect of eating on BIS was examined. Forty-six females attending a commercial weight loss group completed measures of shape and weight concerns, appearance beliefs and dietary restraint, followed by completion of a diary that assessed state BIS, mood and perceived calorie intake immediately following evening meals. Regression analysis indicated that after controlling for mood, state BIS was associated with higher BMI and dietary restraint. Greater variability in state BIS was associated with greater variability in perceived calorie intake. This relationship was fully mediated by greater variability in mood. The findings imply that state BIS warrants investigation as a process that may influence weight loss management.

Validating the Body Uneasiness Test (BUT) in obese patients

OBJECTIVE

To investigate the psychometric properties of the Body Uneasiness Test (BUT) in a large sample of subjects with obesity seeking treatment. BUT is a 71-item self-report questionnaire in two parts: BUT-A which measures weight phobia, body image concerns, avoidance, compulsive self-monitoring, detachment and estrangement feelings towards one's own body (depersonalization); and BUT-B, which looks at specific worries about particular body parts or functions.

METHODS

We recruited a clinical sample of 1,812 adult subjects (age range 18-65 years, females 1,411, males 401) with obesity (Body Mass Index, BMI > or = 30 kg/m2) and a normal weight (BMI value between 18.5 and 25 kg/m2) non-clinical sample of 457 adult subjects (females 248, males 209) with an Eating Attitudes Test-26 (EAT-26) score under the cut-off point 20 (scores > or = 20 indicate possible cases of eating disorders).

RESULTS

The exploratory and confirmatory analyses confirmed a structural five-factor model for BUT-A and an eight-factor model for BUT-B. Internal consistency was satisfactory. Concurrent validity with Binge Eating Scale (BES) and Three-Factor Eating Questionnaire (TFEQ) was evaluated. The authors calculated mean values for BUT scores in adult (18-65 years) patients with obesity, and evaluated the influence of gender, age and BMI. Females obtained statistically significant higher scores than males in all age groups and in all classes of obesity; patients with obesity, compared with normal weight subjects, generally obtained statistically significant higher scores, but few differences could be attributed to the influence of BMI.

CONCLUSION

The BUT can be a valuable multidimensional tool for the clinical assessment of body uneasiness in obesity; the scores of its sub-scales do not show a linear correlation with BMI values.
