Heuchan GN, Lally PJ, Beeken RJ, Fisher A, Conway RE. Perception of a need to change weight in individuals living with and beyond breast, prostate and colorectal cancer: a cross-sectional survey. J Cancer Surviv 2024; 18:844-853. [PMID: 36701100 PMCID: PMC11081928 DOI: 10.1007/s11764-023-01333-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 01/05/2023] [Indexed: 01/27/2023]
Abstract
PURPOSE People living with and beyond cancer (LWBC) are advised to achieve a body mass index (BMI) within the healthy range (≥ 18.5 and < 25). Not perceiving a need for weight change may be a barrier to achieving a healthy weight. This study aimed to explore factors associated with perceived need for weight change among people LWBC. METHODS Adults diagnosed with breast, prostate, or colorectal cancer were recruited through National Health Service sites in Essex and London. Participants (N = 5835) completed the 'Health and Lifestyle After Cancer' survey, which included a question on perceived need to change weight. Associations between perceived need for weight change and BMI, and perceived need for weight change and health and demographic variables, were analyzed using chi-square tests and logistic regression, respectively. RESULTS The proportion of participants perceiving a need to lose weight differed according to BMI category: healthy weight (23%), overweight (64%), obese (85%) (P < 0.001). Having overweight or obesity but not perceiving a need to lose weight was associated with being older, male, non-white, not married or cohabiting, and having cancer that had spread, no formal qualifications, no comorbidities, and having received chemotherapy. CONCLUSIONS Perceived need to lose weight is prevalent among people LWBC with obesity and overweight. This group may be interested in weight management support. Demographic and health factors were associated with having obesity or overweight but not perceiving a need to lose weight. IMPLICATIONS FOR CANCER SURVIVORS Weight loss interventions for people LWBC are needed. A subset of people LWBC with overweight and obesity may need additional information or motivators to engage with weight management.

Abstract
BACKGROUND The association between weight and depressive symptoms is well established, but the direction of effects remains unclear. Most studies rely on body mass index (BMI) as the sole weight indicator, with few examining the aetiology of the association between weight indicators and depressive symptoms. METHODS We analysed data from the Twins Early Development Study (TEDS) and UK Adult Twin Registry (TwinsUK) (7658 and 2775 twin pairs, respectively). A phenotypic cross-lagged panel model assessed the directionality between BMI and depressive symptoms at ages 12, 16, and 21 years in TEDS. Bivariate correlations tested the phenotypic association between a range of weight indicators and depressive symptoms in TwinsUK. In both samples, structural equation modelling of twin data investigated genetic and environmental influences between weight indicators and depression. Sensitivity analyses included two-wave phenotypic cross-lagged panel models and the exclusion of those with a BMI <18.5. RESULTS Within TEDS, the relationship between BMI and depression was bidirectional between ages 12 and 16 with a stronger influence of earlier BMI on later depression. The associations were unidirectional thereafter with depression at 16 influencing BMI at 21. Small genetic correlations were found between BMI and depression at ages 16 and 21, but not at 12. Within TwinsUK, depression was weakly correlated with weight indicators; therefore, it was not possible to generate precise estimates of genetic or environmental correlations. CONCLUSIONS The directionality of the relationship between BMI and depression appears to be developmentally sensitive. Further research with larger genetically informative samples is needed to estimate the aetiological influence on these associations.

Abstract
Weight stigma is a pervasive form of discrimination worldwide. News media, and news images in particular, can reinforce weight stigma by portraying persons with obesity in a negative, stereotypical manner. Informed by the model of stigma communication, this study conducted a content analysis of images accompanying obesity-related news articles from the U.S. and U.K. to determine and compare the prevalence of stigmatizing images. Images (N = 445) in obesity-focused news articles obtained from the top four most viewed online news in the U.S. (n = 244) and U.K. (n = 201) during August 2018-August 2019 were systematically coded. These 445 images featured 228 individuals. Of these 228 individuals, 35% were identified as higher weight and 44% as lower weight. Overall, 70% of persons of higher weight in these news images were depicted in a stigmatizing manner. Further, 46% of individuals with higher weight were depicted with their head partially or fully removed from the image, compared to 25% of individuals with lower weight. Additionally, U.K. news were 2.5 times more likely to contain stigmatizing images than U.S. news. These findings highlight the prevalence of weight stigma in news images and suggest that broader systemic efforts are needed by the news media industry to eliminate the use of negative imagery that marginalizes persons of higher weight.

Weight self-misperception and obesity-related knowledge, attitudes, lifestyle behaviours and cardio-metabolic markers among Chinese school-aged children and adolescents. Public Health Nutr 2023; 26:1549-1561. [PMID: 37092759 PMCID: PMC10410384 DOI: 10.1017/s1368980023000630] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2022] [Revised: 03/09/2023] [Accepted: 03/22/2023] [Indexed: 04/25/2023]
Abstract
OBJECTIVE The relationships between childhood weight self-misperception and obesity-related factors particularly health markers have not been extensively discussed. This study aims to examine the associations between weight self-misperception and obesity-related knowledge, attitudes, lifestyles and cardio-metabolic markers among Chinese paediatric population. DESIGN Cross-sectional study. SETTING Data sourced from a national survey in Chinese seven provinces in 2013. PARTICIPANTS Children and adolescents aged 5-19 years. RESULTS Of the total 14 079 participants, there were 14·5 % and 2·2 % participants over-estimated and under-perceived their weight, respectively. Multi-variable logistic regression was applied to calculate OR and 95 % CI (95 % Cl) of obesity-related behaviours and cardio-metabolic markers by actual and perceived weight status. Individuals who perceived themselves as overweight/obese were more likely to have prolonged screen time, insufficient dairy intake and over sugar-sweetened beverages consumption (all P < 0·05), regardless of their weight. Furthermore, actual overweight/obese individuals had higher odds of abnormal cardio-metabolic markers, but a smaller magnitude of association was found among weight under-estimators. Among non-overweight/obese individuals, weight over-estimation was positively associated with abdominal obesity (OR: 10·49, 95 % CI: 7·45, 14·76), elevated blood pressure (OR: 1·30, 95 % CI: 1·12, 1·51) and dyslipidemia (OR: 1·43, 95 % CI: 1·29, 1·58). CONCLUSIONS Weight over-perception was more prevalent than under-estimation, particularly in girls. Weight over-estimators tended to master better knowledge but behave more unhealthily; both weight over-perception and actual overweight/obesity status were associated with poorer cardio-metabolic markers. Future obesity intervention programmes should additionally pay attention to the population with inaccurate estimation of weight who were easily overlooked.

Abstract
Weight misperception has been seen as a threat to public health. We aimed to understand the meaning of weight misperception by examining associations of weight perception with body satisfaction and body awareness along with healthy ideals and culturally normative body ideals. Undergraduates with higher weights at a Mid-South University (n = 166) completed survey measures that included: weight status perception ("How do you think of yourself in terms of weight?"), self-reported weight and height (used to indicate awareness), current and ideal body size using Figure Rating Scales (FRS), three measures of body satisfaction (difference between current and ideal figures on FRS, Appearance Evaluation subscale of the Multidimensional Body Self-Relations Questionnaire, Body Dissatisfaction subscale of the Eating Disorder Inventory-3). Height and weight were also measured. Thirty percent (n = 49) of participants perceived themselves as 'healthy' weight and 70 % (n = 117) perceived themselves as above healthy weight. In bivariate analyses, there were no significant differences in identification of healthy or culturally normative body ideals by weight perception group. A series of logistic regression models were run to examine associations between weight perception and both BMI awareness and body satisfaction. In unadjusted and adjusted models, increased body satisfaction was associated with reduced odds of perceiving oneself above healthy weight (OR: 0.25, p < 0.001); BMI awareness was not associated with weight misperception. Findings suggest that weight misperception reflects body satisfaction, and not a lack of awareness of body weight/size, definitions of healthy bodies, or culturally normative body ideals. "Correcting" individuals who perceive their bodies as about right has the potential to cause great harm and should be eliminated as a public health goal.

The Association between Body Weight Misclassification in Adolescence and Body Fat and Waist Circumference in Adulthood: A Longitudinal Study. Nutrients 2022; 14:nu14224765.

Abstract
This study examined the longitudinal association between adolescent body weight misclassifications and body fat and waist circumference during adulthood. A sample was derived from a large Australian birth cohort study. The data analyses were restricted to 1002 participants for whom data on both measured and perceived weight at a 14-year follow-up and the actual measure of adult body fat and waist circumference at a 30-year follow-up were available. To determine misclassifications, we compared the perceived weight with the measured weight. The results were presented as means and mean differences (with a 95% confidence interval) of the body fat percentages and waist circumference levels across the weight misclassification groups, adjusting for potential covariates. For both male and female adolescents, weight underestimation was significantly associated with an increase in body fat percentages and waist circumference in adulthood as compared to those who correctly estimated their weight. In the mean difference analyses, adolescent males and females who underestimated their weight were found to have significantly higher body fat, and waist circumference means than those who correctly estimated their weight in the unadjusted and adjusted comparisons. The adolescent males who overestimated their weight had higher body fat, and waist circumference means when they reached adulthood. Increased awareness of weight misclassification and actual weight among adolescents might contribute to better control of weight gain in adulthood.

The mediating effect of perceiving close relatives as obese on obesity and weight control behavior score among adults: An exploratory cross-sectional study in Chongqing, China. Front Public Health 2022; 10:984588. [PMID: 36419990 PMCID: PMC9676925 DOI: 10.3389/fpubh.2022.984588] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Accepted: 09/12/2022] [Indexed: 11/09/2022] Open
Abstract
Obesity is one of the most glaringly obvious, yet most neglected, public health problems the world is facing today. Individuals' self-perception of being overweight is essential to engaging in weight control behavior. This is the first exploratory study in Chongqing to assess the mediating effect of perceived obesity in close relatives on obesity and weight control behavior among adults. A cross-sectional study, including 3,7492 participants, was conducted in a healthcare center in Chongqing, China. For Kruskal-Wallis test analyses, logistic regression and Sobel-Goodman mediation tests were employed. Only 1.76% of participants (660) were medically identified as obese, and only 2.13% of participants (798) thought their close relatives were obese. Nearly one-third of the participants consumed more than double the daily recommended amount of meat. More than 85% of participants were physically inactive. Obesity was positively associated with obesity perception in close relatives (OR = 19.556, P < 0.001). The association between the respondent's obesity status and weight control behavior scores changed statistically significantly (β = 0.594, P < 0.001). Individuals who perceived their close relatives as obese were more likely to engage in weight control behavior themselves (β = 0.678, P = 0.001). The obesity perception in close relatives partially mediated the association between obesity and weight control behavior (ab = 0.141, SE = 0.03, 95% CI = 0.086, 0.198). Obese people are more likely to engage in weight control behaviors. The effect of individuals' obesity status on weight control behavior scores is partially mediated by the obesity perception in close relatives among the participants. Findings suggest that personal obesity status perceptions of close relatives might provide new weight management ideas for healthcare centers.

Abstract
This research aimed (1) to examine the agreement between body mass index (BMI)-based nutritional status and perceived nutritional status overall and by socio-demographic factors and (2) to state the association between the accuracy of weight perception and weight control practices in the Chilean adult population. A population-based cross-sectional study was carried out with 5,192 Chilean adult participants from the Chilean National Health Survey 2016–2017. Agreement between BMI-based weight status and body weight perception for the total sample and across subgroups was determined using the weighted kappa coefficient. The agreement between BMI-based and perceived nutritional status of the total sample was fair (kappa = 0.38). A higher rate of weight perception accuracy was identified in women, younger respondents, and participants with higher education, a higher income, and from urban areas than their counterparts. Respondents with overweight or obesity tended to underestimate their nutritional status. Actions to lose weight were higher in those who had the right perception of their overweight/obesity condition and those who overestimated their body weight, regardless of their nutritional status. In all groups, weight loss behaviors were more related to the perceived than the BMI-based nutritional status. The consequences of accurate perception of the nutritional status are discussed including its effects on body weight and mental health.

Association between CYP metabolizer phenotypes and selective serotonin reuptake inhibitors induced weight gain: a retrospective cohort study. BMC Med 2022; 20:261. [PMID: 35879764 PMCID: PMC9317126 DOI: 10.1186/s12916-022-02433-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2021] [Accepted: 06/13/2022] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND Prescription medications such as selective serotonin reuptake inhibitors (SSRIs), commonly used to treat depression, are associated with weight gain. The role of pharmacogenomics in predicting SSRI-induced weight gain is unclear. METHODS In this retrospective cohort study from participants in the Mayo Clinic RIGHT study who were prescribed citalopram, paroxetine, sertraline, or fluoxetine, our aim was to evaluate the association of metabolizer phenotype and total body weight after 6 months of SSRIs initiation. We evaluated the metabolizer phenotypes (poor/intermediate, normal, and rapid/ultra-rapid) of the cytochromes P450 enzymes genes: CYP2C9, CYP2C19, and CYP2D6 known to influence the metabolism of SSRI medications: CYP2C19 for citalopram, CYP2D6 for paroxetine, CYP2D6 and CYP2C19 for sertraline, and CYP2D6 and CYP2C9 fluoxetine. In addition, we assessed the association of metabolizer phenotype and total body weight change at six months following SSRI prescription using parametric analysis of covariance adjusted for baseline body weight and multivariate regression models. RESULTS CYP2C19 poor/intermediate metabolizers prescribed citalopram gained significantly more weight than normal or rapid/ultra-rapid metabolizers at 6 months (TBWG %: 2.6 [95% CI 1.3-4.1] vs. 0.4 [95% CI -0.5 - 1.3] vs. -0.1 [-95% CI -1.5-1.1]; p = 0.001). No significant differences in weight outcomes at six months of treatment with paroxetine, sertraline, or fluoxetine were observed by metabolizer status. CONCLUSIONS Weight gain observed with citalopram may be mediated by CYP2C19 metabolizer status.

Abstract
BACKGROUND Obesity has become a noticeable public health problem, especially in the young population. Bariatric surgery is growing in China but it is still new to the general public. Knowledge and attitudes towards obesity and bariatric surgery in university students are important to national health decision-making. OBJECTIVES To study the knowledge and attitudes towards obesity and bariatric surgery among Chinese university students. METHODS A self-designed questionnaire was distributed to university students to fill in online from June to July 2021. RESULTS A total of 3199 questionnaires were received, with an effective rate of 98.58% (3154 questionnaires). 65.44% of whom had normal BMI and 12.14% of whom were overweight or in obesity. More than 80% of them had a high knowledge of the common causes and complications of obesity but lacked knowledge of the relationship between obesity and bone and joint, tumor or cancer, and reproductive diseases. 51.55% of them thought they needed to lose weight, especially female students (P < 0.01). Only 39% had regular physical exercise habits, 58.62% of them could reasonably control their diet, and more than 2/3 of them (67.82%) often stayed up late. Safety (29.77%) and effectiveness (29.3%) of bariatric surgery were not well accepted. Among medical students, education positively affected knowledge and attitudes towards bariatric surgery (P < 0.05). Mass media and social platforms were the main sources for obtaining obesity and weight-loss information. CONCLUSIONS Chinese university students have insufficient knowledge of obesity and related complications, lack of scientific management of their own weight, and poor acceptance of bariatric surgery. More education is needed on this issue.

Abstract
Obesity is a chronic disease associated with impaired physical and mental health. A widespread view in the treatment of obesity is that the goal is to normalize the individual's body mass index (BMI). However, a modest weight loss (usually above 5%) is already associated with clinical improvement, while weight losses of 10%-15% bring even further benefits, independent from the final BMI. The percentage of weight reduction is accepted as a treatment goal since a greater decrease in weight is frequently difficult to achieve due to metabolic adaptation along with environmental and lifestyle factors. In this document, the Brazilian Society of Endocrinology and Metabolism (SBEM) and the Brazilian Society for the Study of Obesity and Metabolic Syndrome (ABESO) propose a new obesity classification based on the maximum weight attained in life (MWAL). In this classification, individuals losing a specific proportion of weight are classified as having "reduced" or "controlled" obesity. This simple classification - which is not intended to replace others but to serve as an adjuvant tool - could help disseminate the concept of clinical benefits derived from modest weight loss, allowing individuals with obesity and their health care professionals to focus on strategies for weight maintenance instead of further weight reduction. In future studies, this proposed classification can also be an important tool to evaluate possible differences in therapeutic outcomes between individuals with similar BMIs but different weight trajectories.

Abstract
Mass media advertising promoting healthy weight and lifestyles represents an important approach to the prevention of non-communicable diseases. However, concerns have been raised that advertisements promoting a healthy weight may be stigmatizing and contribute to negative outcomes. This study explored the potential negative and positive cognitive, psychological, and behavioral intention outcomes of exposure to different public health campaign advertisements that promote positive behavior change and healthy weight. A total of 1,098 adult residents of the United Kingdom (50% female, Mage = 35.21 years) viewed one of four video advertisements: one control advertisement and three healthy weight and lifestyle advertisements that differed in message content (negative health impacts, support/encouragement, and social norms) and execution style (graphic, animation, and depicted scene). Participants then responded to items assessing a variety of cognitive, psychological, and behavioral intention outcomes. Compared to those in the control condition, those exposed to a healthy weight and lifestyle advertisement reported significantly higher scores for (i) perceptions of weight stigma, (ii) negative emotions, and (iii) intentions to engage in adaptive lifestyle behaviors. There were no differences observed between conditions for maladaptive behavioral intentions, internalized weight bias, anti-fat attitudes, and body dissatisfaction. The advertisement featuring a supportive/encouraging message and animation style performed most favorably. Results suggest that healthy weight and lifestyle advertisements have the potential to promote positive behavior change but may be associated with some negative outcomes. Of the assessed communication approaches, a supportive/encouraging message with animation style appears least likely to induce negative emotions and is preferred for minimizing weight stigma.

Abstract
Abstract
Study aim: In this study, it is aimed to find out the exercise preferences based on the Body Mass Index (BMI) and Body Weight Perception (BWP), and to determine the consistency between BMI and BWP calculated via the self-reporting method.
Material and methods: The study was conducted total of 297 volunteers, included 174 females (Mage = 27.19 ± 9.94 years) and 123 males (Mage = 26.08 ± 10.15 years), who were members of the physical activity center. The height and body weight values were obtained based on the self-reports. BWP was assessed by asking “how do you describe your weight?” As a statistical analysis, the Pearson chi-square test and Kappa statistics were used.
Results: It was determined that overweight/obese female prefered most the strength exercises, whereas, overweight/obese men, according to both methods, preferred the different kind of exercises (p < 0.05). When the mutual consistency of the BWP and BMI methods was compared, “average” level conformity was found in female, and “weak” level conformity was found in male (Female: κ = 0.48; p < 0.000; Male: κ = 0.21; p < 0.001).
Conclusion: It could be said that the type and application protocol of the exercise has been related with the frequency and duration of the exercise for both of the methods. Besides, it could be said that there was a higher consistency among female participants at the level of participating to the exercise and they had similar exercise preference, frequency and duration.

Abstract
Obesity has become a serious public health problem worldwide and is linked to an increased risk of non-communicable diseases (NCDs). Poor self-perception of body weight is postulated to play a negative role in curbing increased rates of obesity. This study investigated the views of own body weight and perceived risk of developing NCDs in South African adults. This was a community-based quantitative study. Descriptive statistics were used, and logistic regression analysis was conducted on the data. A total of 1050 respondents took part in the study. Of the 161 respondents who perceived themselves to be normal weight, 98.8% (n = 159) misperceived their body weight. The majority of respondents (>90%) who were overweight according to the calculated BMI perceived no risk of developing obesity-related diseases. Most of the respondents, 46% (n = 253), believed that body weight was influenced by heredity. The method used for weight loss by 57% (n = 173) of the respondents was exercising at home. There was a statistically significant association between Body Mass Index (BMI), employment status, risk of developing diabetes, and body weight misperception (p < 0.05). Misperception of body weight was common among the study respondents and may influence weight control intervention strategies. Health promotion targeting personal behaviour, such as body weight self-perception, is crucial in supporting targeted strategies to address obesity in South Africa.

Abstract
Background: To examine the association between body size perception (BSP) and body size dissatisfaction (BSD) in elementary school children and to document the potential contribution of individual factors [age, sex, and actual body size (BMI Z-scores: BMIZ)] that may influence their relationship. Methods: This study included 269 children (124 boys and 145 girls) between 6 and 13 years of age (9.2 ± 1.6 years). The BSP score was calculated as the difference between the perceived actual body size and BMIZ (actual body size). A negative BSP score indicated an underestimation of their body size. To assess the BSD score, the difference between perceived actual body size and desired body size was calculated. A positive BSD score indicated a desire to be thinner. Results: Perceived actual body size was smaller than BMIZ, independent of age group and weight status. Overall, 64% of children underestimated their body size. The young children living with obesity demonstrated the highest misperception. Results also showed that the proportion of children who desired to be thinner was higher in overweight and obese subgroups. No significant relationship was found between BSP and BSD scores in the entire sample, while a positive association was observed among younger children in the normal-weight and obese subgroups (r = 0.40; p < 0.001 and r = 0.78; p < 0.05, respectively). Conclusions: Underestimation and dissatisfaction of body size are more prevalent in children living with overweight/obesity. Moreover, there is an association between BSP and dissatisfaction, yet this association is dependent on age and weight status.

Association of body image dissatisfaction, behavioral responses for healthy eating, and cardiovascular health in African-American women with overweight or obesity: A preliminary study. Am J Prev Cardiol 2021; 8:100254. [PMID: 34632436 PMCID: PMC8487888 DOI: 10.1016/j.ajpc.2021.100254] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/24/2021] [Revised: 09/01/2021] [Accepted: 09/16/2021] [Indexed: 12/14/2022] Open
Abstract
BACKGROUND African-American (AA) women have the lowest prevalence of ideal categorizations of diet and body mass index (BMI), as defined by the American Heart Association (AHA) Life's Simple 7 (LS7) cardiovascular health (CVH) components compared to other racial/ethnic groups, regardless of sex/gender. There is limited research exploring the interplay of unique psychosocial influences on CVH such as body image dissatisfaction (BID) and behavioral responses for healthy eating among AA women with overweight or obesity. OBJECTIVE This study aimed to assess the association of BID with behavioral responses for healthy eating and LS7 components. METHODS A cross-sectional analysis of baseline data was conducted among 32 AA women with overweight or obesity from a larger, community-based participatory research study. Self-reported measures were used to assess BID and behavioral responses to healthy eating (diet self-regulation to reduce fat or caloric intake and motivation for healthy eating [intrinsic motivation and integrated regulation]) using previously validated instruments. The LS7 components (e.g., BMI, diet, etc.) and composite score were evaluated using the AHA LS7 metrics rubric. RESULTS Women with no or lower BID had greater diet self-regulation to reduce fat or caloric intake (mean, 3.5 vs 3.0; P=.05), intrinsic motivation for healthy eating (mean, 5.3 vs 4.2; P=.01), and integrated regulation for healthy eating (mean, 5.3 vs 3.7; P=.002) than those with higher BID. These significant differences remained after adjustment for BMI. Women with higher BID had a higher proportion of BMI within the obesity range compared with those with no or lower BID (94.4% vs 57.1%, P=.03). BID was not significantly associated with other LS7 components or composite score. CONCLUSION BID and other psychosocial influences for healthy eating are potential targets for culturally tailored lifestyle interventions among AA women.

Abstract
OBJECTIVE Given the increased prevalence of eating disorders (EDs) among individuals higher on the weight spectrum, we aimed to 1) report the prevalence of ED patients in higher levels of care (residential, partial hospitalization, and intensive outpatient) attributing the onset of their ED to anti-obesity messaging, 2) report the most commonly recollected sources of those messages, and 3) determine if those attributing the onset of their ED to anti-obesity messaging a) enter, b) exit, and c) respond to treatment differently from peers who did not. METHODS This retrospective cohort study used data from 2901 patients receiving ED treatment in higher levels of care at a US-based center between 2015 and 2018. Multilevel models examined differences in ED symptoms and trajectories of change over time. NVivo was used to analyze the patients' comments about sources of messages. RESULTS Eighteen percent attributed their ED onset to anti-obesity messaging, 45% did not, and 37% were unsure. Of those providing comments, the most common sources included the following: educational curriculum/school context (45.9%), media/Internet (24.7%), health care (10.4%), family (9%), and peer bullying (3.7%). At admission, patients attributing their ED onset to anti-obesity messaging had more severe ED symptoms than those who did not (γ = 0.463, standard error [SE] = 0.086, p < .001) and those who were unsure (γ = 0.288, SE = 0.089, p < .001); no differences were evident at discharge (p > .483). During phase 2 of treatment, patients attributing their ED onset to anti-obesity messaging improved faster than those who did not (γ = 0.003, SE = 0.001, p = .008) and those who were unsure (γ = 0.003, SE = 0.001, p = .014). CONCLUSIONS Anti-obesity messaging may put vulnerable individuals at risk for EDs. We recommend increasing weight bias training for school personnel and health care professionals. To reduce health disparities, we also suggest the promotion of weight-neutral health-enhancing self-care practices in media and public health campaigns, legislative policies, and health care overall.

Abstract
PURPOSE Normal weight obesity (NWO), defined as normal body mass index (BMI) and excessive body fat percentage (BF%), has been shown to be associated with a significantly higher risk of developing metabolic syndrome, cardiometabolic dysfunction and with higher mortality. However, there is limited literature regarding the potential associations between NWO and lifestyles. This study aimed to investigate the associations of lifestyles with NWO in Chinese university students. PARTICIPANTS AND METHODS A total of 279 university students with normal BMI were recruited and divided into NWO and normal weight non-obesity (NWNO) groups by BF%. Body composition and anthropometrics were measured, and participants were asked to finish the Healthy Lifestyle Scale for University Students (HLSUS) questionnaire. RESULTS A total of 26 male (25.5%) and 71 female (40.1%) students were identified as NWO. Compared to NWNO students, body weight, BMI, body fat mass, visceral fat area, waist circumference and hip circumference of NWO students were all significantly higher both in male and female students (P < 0.05). The body fat mass, BF% and visceral fat area were significantly negatively correlated with the total HLSUS, physical exercise behavior, and dietary nutrition behavior scores in NWNO males, NWO and NWNO females (P < 0.05). The risk of NWO was lower in those students with higher scores in physical exercise behavior in both males (OR = 0.298, 95% CI = 0.121~0.733) and females (OR = 0.653, 95% CI = 0.505~0.843), while dietary nutrition behavior (OR = 0.759, 95% CI = 0.584~0.986) and stress management behavior (OR = 0.503, 95% CI = 0.335~0.755) decreased the risk of NWO only in females. CONCLUSION The incidence of NWO was high among university students, especially in females, which might be related with unhealthy lifestyles. NWO university students should pay attention to lifestyle adjustments, especially physical exercise, dietary nutrition and stress management, for preventing the health risk in NWO.

Dietary Patterns, Weight Perception and Obesity Status, among 10-12-Year-Old Children; an Epidemiological Study in Greece. CHILDREN-BASEL 2021; 8:children8080626. [PMID: 34438517 PMCID: PMC8393401 DOI: 10.3390/children8080626] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/12/2021] [Revised: 07/07/2021] [Accepted: 07/20/2021] [Indexed: 12/14/2022]
Abstract
Adherence to certain dietary patterns influences obesity status in both children and adults. Weight perception influences dietary habits. The aim of this study was to examine children’s dietary habits and obesity status, in relation to weight perception. One thousand seven hundred Greek students enrolled in this study during 2014–2016. Children’s characteristics were assessed through validated questionnaires, and weight status was classified according to the criteria of the International Obesity Task Force. Dietary patterns were assessed through exploratory factor analysis. Overall, 52.2% of children characterized themselves as normal weight, 34.5% as low weight, and 13.3% as overweight/obese; 52.5% of children were in accordance with their actual weight status, with girls being more likely to overestimate their weight. Children followed three dietary patterns, i.e., starchy and protein foods, unhealthy/high-fat foods, and healthy foods. Children who followed the healthy dietary pattern and had accurate weight perception (in accordance with their actual weight), had lower odds of being overweight/obese (p < 0.001). Accurate weight perception in conjunction with healthy dietary habits may play a determinant role in the prevention of obesity. From a public health perspective, early identification of children’s weight misperception along with healthy dietary habit promotion shape a crucial role in childhood obesity confrontation.

Abstract
BACKGROUND Currently, weight loss remains the main management strategy for NAFLD, but the weight loss intention and methods remain poorly characterized. METHODS We analysed data about the perception of weight status, intention and methods to lose weight amongst 3,822 persons with NAFLD (United States Fatty Liver Index ≥ 30) from the National Health and Nutrition Examination Survey, 2001-2014. RESULTS Only 53.9% of people with NAFLD intended to lose weight, 91.8% with perception of overweight and 8.2% with normal weight perception. Persons with perception of overweight or overweight/obese status were four times more likely to try to lose weight (adjusted odds ratios 3.9 and 4.2, respectively, both P < 0.0001). Younger age, women, higher educational level, Hispanic and blacks (versus whites) were significant independent factors associated with weight loss intention. Notably, ≤10% attended weight loss programme. Metabolic equivalent of task hours per week was significantly higher in whites who exercised to lose weight (vs. no exercise, P = 0.003) but not in other racial/ethnic groups. Interestingly, calorie intake was similar between those who dieted versus not (2056 vs. 1970 kcal/day, P = 0.11). About 30% reported ≥ 10-lb weight loss, with 50% higher odds of success for men but there was no difference by race/ethnicity. CONCLUSION Overweight or obese perception was a key driver in weight loss activities but was inconsistent with actual weight status and varied by race/ethnicity and other sociodemographic factors. Weight loss programme is under-utilized and should take in account of weight perception training and culturally appropriate approach.

Abstract
Individuals who perceive themselves as "overweight" experience higher negative body-related self-conscious emotions than those who do not. Theoretical and empirical evidence suggests internalized weight stigma may be an important mediator of the relationship between weight perception and self-conscious emotions. Overcoming common measurement limitations and sampling limitations, the present study investigated whether gender moderates the associations among weight perceptions, internalized weight stigma, and negative body-related self-conscious emotions in 104 young adults (64 % women). Individuals who perceived themselves as too heavy (52 %) experienced higher body-related shame and guilt compared to those who perceived themselves as about right. Internalized weight stigma mediated these associations in women but not men, such that perceiving oneself as too heavy was associated with higher internalized weight stigma, which was associated with higher body-related shame and guilt in women. Results underscore the importance of internalized weight stigma as a potential target for intervention among women of diverse weight statuses who are prone to experiencing body-related shame and guilt.

Body size ideals and body satisfaction among Dutch-origin and African-origin residents of Amsterdam: The HELIUS study. PLoS One 2021; 16:e0252054. [PMID: 34038446 PMCID: PMC8153493 DOI: 10.1371/journal.pone.0252054] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Accepted: 05/07/2021] [Indexed: 11/19/2022] Open
Abstract
OBJECTIVE Obesity is highly prevalent among ethnic minorities and acceptance of larger body sizes may put these ethnic minorities at risk of obesity. This study aimed to examine body size ideals and body satisfaction in relation to body weight, in two Sub-Saharan African (SSA)-origin groups in the Netherlands compared to the Dutch. Additionally, in the two SSA-origin groups, this study assessed the mediating role of acculturation in the relation between ethnicity and body size ideals and body satisfaction. METHODS Dutch, African Surinamese and Ghanaians living in Amsterdam, the Netherlands, participated in the observational HELIUS study (n = 10,854). Body size ideals were assessed using a validated nine figure scale. Body satisfaction was calculated as the concordance of current with ideal figure. Acculturation was only assessed among SSA-origin participants and acculturation proxies included age of migration, residence duration, ethnic identity and social network. Weight and height were measured using standardised protocols. RESULTS SSA-origin women and Ghanaian men had larger body size ideals compared to the Dutch; e.g. Surinamese and Ghanaian women had 0.37 (95%CI 0.32; 0.43) and 0.70 (95%CI 0.63; 0.78) larger body size ideals compared to Dutch women. SSA-origin participants were more often satisfied with their weight compared to the Dutch. Similarly, SSA-origin participants had more than twice the odds of being satisfied/preferring a larger figure compared to the Dutch (e.g. BSurinamese men 2.44, 95%CI 1.99; 2.99). Within the two SSA-origin groups, most acculturation proxies mediated the relation between ethnicity and body size ideals in women. Limited evidence of mediation was found for the outcome body satisfaction. CONCLUSION Public health strategies promoting a healthy weight may need to be differentiated according to sex and ethnic differences in body weight perception. Factors other than acculturation may underlie the ethnic differences between African Surinamese and Ghanaians in obesity.

Abstract
This project investigated how alternative non-stigmatising public health messages influence people's health behaviours and well-being, relative to traditional stigmatising weight-loss messages. We conducted three experimental studies (total N = 1281) that compared traditional weight-loss messages to weight-neutral messages (Study 1), weight-inclusive messages (Study 2) and size acceptance messages (Study 3). Results revealed that public health messages have differential effects on health behaviours and well-being, depending on the audience's BMI or perceived weight. However, campaigns that challenge weight stigma and promote body positivity have positive effects on some psychological indicators of health and well-being for people of all body sizes.

Abstract
Introduction: Ghrelin is an orexigenic hormone which favors food-seeking behavior and has been postulated to be a biomarker of stress. We conducted a systematic review and meta-analysis on the evolution of ghrelin levels following acute stress. Methods: The PubMed, Cochrane Library, Embase, and ScienceDirect databases were searched for studies reporting ghrelin levels before and after acute stress in humans. Results: We included ten studies for a total of 348 patients. Acute stress (intervention) was always in a laboratory. Acute stress was psychological (Trier Social Stress Test), physical, or mixed (cold pressure test). The overall meta-analysis demonstrated an increase in ghrelin after the stress intervention (ES = 0.21, 95CI 0.09 to 0.34) compared with baseline levels. Stratification by time demonstrated an acute increase in ghrelin levels in the five minutes immediately following the initiation of stress (0.29, 0.10 to 0.48) but without any difference after. Obese individuals had a more significant (ES = 0.51, 95CI 0.18 to 0.84) and prolonged increase in ghrelin levels for up to 45 min compared with non-obese individuals who had a significant increase only five minutes after stress. Moreover, the ghrelin levels increased in response to stress with BMI (coefficient 0.028, 0.01 to 0.49; p = 0.013) and decreased with the time after the stress intervention (coefficient -0.007, −0.014 to −0.001; p = 0.025). Conclusion: Ghrelin is a biomarker of stress, with a short-term increase following acute stress. Obese individuals have both a higher and prolonged response, emphasizing the link between obesity and stress.

Abstract
OBJECTIVE To examine body image perception and the associations of body dissatisfaction (BD) with socio-demographic and lifestyle factors among Saudi women attending fitness centers in Riyadh. METHODS Saudi females aged 16 years and older were recruited from 12 randomly selected fitness centers in Riyadh, using stratified clustered sampling technique (n = 460). Height and weight were measured to calculate actual body mass index (BMI). A previously validated instrument was used to collect socio-demographic and lifestyle variables including physical activity (PA), sedentary behaviors, sleep and dietary habits. Stunkard Figure Rating Scale silhouettes were used to assess perceived and desired body shape. RESULTS The participants had a mean (SD) age of 29.2 (8.2). The majority were not married (57%), with no children (66%) and had college degrees (78%). While 63% were overweight or obese, nearly 40% of women underestimated their perceived body shape. The majority of respondents (87%) were dissatisfied with their body shape including 68% of normal weight women. Females who had BD were significantly older, had higher BMI, reported more weight loss attempt and had expended less time in vigorous (p = 0.033) and total (p = 0.042) PA than those who were satisfied with their body shape. However, when adjusting for socio-demographic variables, logistic regression analysis revealed significant associations of BD with higher BMI, shorter membership duration of fitness club, and reduced dairy products and energy drinks consumption. CONCLUSION Except for BMI and decreased dairy products and energy drinks consumption, many lifestyle behaviors did not associate with BD among Saudi females attending fitness centers. The findings can inform healthcare providers when intervention strategy is implicated for females with BD. Future studies should compare the associations of BD with lifestyle behaviors between males and females attending fitness centers and seeking weight loss.

Abstract
The prevalence of obesity is growing unabatedly despite the considerable efforts directed at the problem. Although abundant research has contributed to our understanding of the multifactorial causes of obesity, there is less attention to research that is relevant for guiding social marketers, public health professionals and policymakers in delivering public health interventions for countering and/or preventing the problem of obesity. This review offers six points for identifying and developing research relevant for guiding community-wide obesity interventions based on the idea that an applied marketing research perspective offers a better model for identifying effective interventions than more theoretical academic research. Specifically, the research guiding public health and social marketing interventions needs to (1) provide information on ultimate outcomes (weight, health and unintended consequences) more than intermediate outcomes (beliefs, attitudes and behaviour), (2) report on observations collected over the longer term, (3) use natural settings (even at a cost of internal validity), (4) endeavour to overcome observer-effects, (5) report effect sizes (rather than statistical significance) and (6) use moderator analyses to capture variation in how a population responds to interventions.

Abstract
AIMS The prevalence of Type 2 Diabetes Mellitus among adolescents in the United States continues to rise, following the trajectory of the obesity epidemic which posits not only a substantial health burden to our society, but also a significant threat to the wellbeing of America's youth. While a number of studies have explored the perception of the risk for developing diabetes in the adult population in the United States, this data is minimal for the adolescent population. In this study, we examined the self-perceived risk of diabetes among adolescents with overweight/obesity. METHODS Cross-sectional study of 808 non-diabetic U.S. adolescents overweight or obese, ages 12-19, who completed a physical exam and in-home interview during the 2011-2014 National Heath and Nutritional Examination Survey (NHANES). RESULTS Of adolescents with obesity, African Americans (aOR 0.27, 95% CI: 0.15, 0.51) and Hispanic Americans (aOR 0.50, 95% CI: 0.28, 0.90) were significantly less likely to perceive themselves as being at risk for developing diabetes/prediabetes compared to Non-Hispanic Whites. Additionally, individuals with overweight (aOR 13.1, 95% CI: 4.54, 37.5) and obesity (aOR 3.40, 95% CI: 1.71, 6.74) who had been informed by their physician that they were at risk for diabetes, were significantly more likely to perceive themselves to be at risk for diabetes. CONCLUSIONS Significant racial differences exist in the self-perceived risk for diabetes among U.S. adolescents with overweight and obesity. Further investigation focused on preventing the development of diabetes among at-risk adolescents who do not comprehend their risk, i.e. through more effective healthcare communication, is warranted.

Abstract
BACKGROUND Weight stigma is pervasive across the U.S. and is associated with poor health outcomes including all-cause mortality. One potential reason that weight stigma may be detrimental to health is that it begets poorer health behaviors. Therefore, the present study tested for associations between weight stigma and four health behaviors (i.e., eating behavior, alcohol use, sleep disturbance, and physical activity), while controlling for BMI and other potential confounds. SUBJECTS/METHODS Participants (N = 2022) in the U.S. were recruited for the Eating in America Study using a Qualtrics panel between December 2019 and January 2020 and were census-matched according to national quotas for age, gender, income, race/ethnicity, and census region. Participants completed questionnaires about weight stigma, health behaviors, demographics, and anthropometric measurements. The current study employed a two-stage investigation: exploratory analyses were first performed on a random sample of the dataset (n = 438), then the remaining unexamined data were used to conduct confirmatory analyses that were preregistered on the Open Science Framework. RESULTS Controlling for BMI, weight stigma was significantly associated with greater disordered eating (b = 0.34, 95% CI [0.31, 0.38], p < 0.001), comfort eating (b = 0.32, 95% CI [0.25, 0.39], p < 0.001), sleep disturbance (b = 0.27, 95% CI [0.20, 0.33], p < 0.001), and alcohol use (b = 0.30, 95% CI [0.11, 0.49], p = 0.002), but not lower physical activity (b = -0.04, 95% CI [-0.13, 0.05], p = 0.402) for individuals across the weight spectrum. BMI and perceived weight status significantly moderated the effects of weight stigma on disordered eating and alcohol use. No gender differences were found. These confirmatory analyses partially replicated the exploratory stage 1 findings. CONCLUSIONS This study provides preliminary evidence that weight stigma is linked to several poor health behaviors, which may impact physical health.

Abstract
Resumo Objetivo Analisar a associação entre perfil alimentar, atividade física e estado nutricional entre mulheres universitárias. Método Estudo transversal com 1500 mulheres. O questionário abordava questões sobre a vigilância de fatores de risco e proteção para doenças crônicas. As associações foram analisadas pelo teste qui-quadrado e análise de correspondência múltipla. Resultados Das 1500 mulheres, 64,3% tinham entre 20 e 29 anos. Aquelas fisicamente ativas consumiram mais frutas (p<0,01), salada (p<0,01) e vegetais/verduras (p<0,01), enquanto as fisicamente inativas consumiram mais refrigerantes (p<0,01), carne com gordura visível (p=0,03) e leite com gordura (p=0,04). As mulheres fisicamente inativas também apresentaram maior prevalência de diabetes mellitus (p<0,01), colesterol elevado (p<0,01) e dislipidemia (p=0,04). Conclusão e implicação para a prática As universitárias apresentaram comportamentos de risco a sua saúde, onde o consumo de álcool, baixo consumo de alimentos saudáveis e a alta prevalência de inatividade física contribuíram para o aumento dos fatores de risco para doenças crônicas. Ações preventivas com a participação de uma equipe multidisciplinar ajudará na melhora da saúde no ambiente acadêmico.

Abstract
Little guidance is available to clinicians on how to talk about weight with their patients. The aim of this study is to explore youth preferences for weight-related conversations. Participants came from the National MyVoice Text Message Cohort. Between 7/2017 and 01/2018, 952 MyVoice participants provided open-ended responses via text message to three questions about weight-related conversations ("Has your doctor ever talked to you about weight?", "What did he or she say?", and "What should a doctor NOT say when talking about weight?"). The presence of themes was coded using standard qualitative methods. Of the 952 respondents, 568 (60%) reported that their doctor had talked with them about weight. Of these, 85% indicated that their doctor had notified them of their weight, BMI, or weight status and/or the need to change their body weight and 16% had doctors who provided advice about weight control. Eight themes emerged from the analysis of responses to the question "What should a doctor NOT say when talking about weight?". The two most common themes were: (1): Avoid stigmatizing terms/language (32%); and (2) Do not shame patient for their weight (25%). Findings suggest that weight-related conversations do not reflect the preferences of the youth they are designed to benefit. Youth recommended that clinicians focus on health and sustainable behavioral solutions, avoid stigmatizing language and comparing them to others, and be aware of the potential harm associated with making assumptions that conflate weight with health behaviors, morality, or appearance.

Abstract
OBJECTIVE Gender analysis in health research is important to strengthen our health system. The current study aimed to explore factors related to body weight misperception in a national sample of the general Korean population. DESIGN Cross-sectional study. SETTING South Korea, general population. PARTICIPANTS 12,900 adults enrolled from the Seventh Korea National Health and Nutrition Examination Survey (2016-2018). RESULTS Disadvantageous socio-economic status was considered a predictor of participants' misperceptions of themselves as being of a healthy weight despite being overweight and as underweight despite being of a healthy weight, mainly in men. Favourable socio-economic status was considered a predictor of participants' misperceptions of themselves as being of a healthy weight despite being underweight and as overweight despite being of a healthy weight, mainly in women. Living in an urban area was an independent predictor of men's misperception of themselves as being of a healthy weight despite being overweight and women's misperception of themselves as being underweight despite being of a healthy weight. Physical inactivity was a predictor of most misperceptions in women. Psychological variables, such as stress and depression, were not significant predictors of misperception. CONCLUSIONS The current study highlighted the gender differences in factors related to body weight misperception. These differences suggested that more sophisticated policies should be formulated to identify solutions to health problems related to body weight.

Abstract
INTRODUCTION A substantial proportion of individuals with overweight or obesity perceive themselves as 'too heavy' relative to 'about right'. Perceiving one's weight as 'too heavy' is associated with lower levels of physical activity and higher levels of sedentary behaviour. However, the mechanisms underpinning the associations between weight perception and lifestyle behaviours have not been identified. Based on theoretical tenets and empirical evidence, the self-conscious emotions of shame and guilt may mediate these associations. METHODS Participants were young adults (n = 618, Mage = 24.0 ± .6 years) who provided data on weight, weight perception, body-related shame and guilt, physical activity and screen time. RESULTS Mediation analyses using the PROCESS macro indicated that shame and guilt significantly mediated the relationships between weight perception and physical activity and shame significantly mediated the relationship between weight perception and screen time. CONCLUSIONS These findings provide preliminary evidence that self-conscious emotions may be mechanisms by which weight perception influences physical activity and sedentary behaviour in young adults. However, longitudinal investigations of this mechanism are needed.

Abstract
The study investigates the association between weight gain perception and weight change over time among Japanese adults. Data were from specific health checkups held in 2013, 2014, and 2015 by National Health Insurance in Fukushima Prefecture, Japan. We included 3677 participants who gained more than 3.0kg between 2013 and 2014. Weight gain perception was asked in 2014 using a questionnaire. The participants who perceived their weight gain of more than 3kg were categorized in the accurate group and those who did not were in the inaccurate group. Multiple linear regression models were used to assess associations between weight gain perception in 2014 and weight change between 2014 and 2015. The models were adjusted for gender, age, weight in 2014, regular physical exercise, daily physical activity, and medication. Results showed that the accurate group (β=0.217; 95% confidence interval=0.037, 0.397; P=0.018) had significantly less weight loss than those in the inaccurate group. We concluded that accurate weight gain perception was associated with an increased risk of future weight gain among Japanese adults.

Abstract
The obesity crisis is one of the largest public health challenges of the 21st century. Population‐level adiposity has increased dramatically in recent times, and people not recognizing that they have overweight or obesity is now common. It has been widely assumed that not recognizing oneself as having overweight is detrimental to weight management and long‐term health. Here, diverse research is reviewed that converges on the counterintuitive conclusion that not recognizing oneself as having overweight is actually associated with more favourable physical and mental health outcomes than recognizing oneself as having overweight. Drawing on existing models in social psychology and weight stigma research, an explanatory model of the health effects of self‐perception of overweight is outlined. This model proposes that self‐perception of overweight triggers social rejection concerns and the internalization of weight stigma, which in turn induce psychological distress and negatively impact health‐promoting lifestyle behaviours. How self‐perception of overweight may in part explain progression from overweight to obesity, and the public health implications of self‐perception of overweight and obesity are also discussed.

Abstract
This study examined whether body weight misclassification continues from adolescence to adulthood and the associated predictors behind that misclassification. Data are from a sample of a longitudinal Australian birth-cohort study. Data analyses were restricted to 2938 participants whose measured and perceived body weights were recorded during their adolescence and adulthood follow-ups. To identify misclassification, we objectively compared their measured and perceived body weights at each follow-up. Potential predictors during early life or adolescence periods were included in data analyses. At each follow-up, underestimation was recorded more often among overweight and obese participants, whereas overestimation was mostly recorded among underweight ones. Over 40% males and females were able to correctly estimate their body weight at one follow-up, whereas almost 30% males and 40% females were able to do so in more than one follow-ups. One-third females and 45% males underestimated their body weight at one follow-up, whereas 13% females and a quarter of males were able to do so in more than one follow-ups. Being female, dieting, being overweight, having an overweight mother, and having poor mental health were the most significant predictors for more than one follow-up misclassifications. Further studies are needed to evaluate the impact of persistent misclassification on population health benefits.

Abstract
Resumo Atualmente a obesidade é considerada um dos maiores desafios da saúde pública. Ela vem sendo enfrentada a partir do incentivo de mudanças comportamentais individuais, exaltando a perda de peso como forma inquestionável de garantir saúde. Tendo em vista este contexto e a importância das Diretrizes brasileiras de obesidade sobre o campo da obesidade, sua influência sobre a prática profissional, o tipo de tratamento incentivado e o processo decisório em relação aos corpos gordos, foi realizada uma análise deste documento, associada à emergente discussão de como o discurso da saúde justifica e reproduz a gordofobia da sociedade. A análise se deu primeiramente em relação à patologização do corpo gordo e como isto é acompanhado de uma valorização do corpo magro. Em seguida, discute-se a abordagem normativa do peso, que propõe intervenções individuais sempre focadas na perda de peso. Pode-se notar que o discurso presente nas Diretrizes reforça a saúde inerente dos corpos magros, reproduz estereótipos relacionados ao corpo gordo e relaciona diretamente quilos perdidos com melhor nível de saúde.

Abstract
INTRODUCTION Stress and obesity are two public health issues. The relationship between obesity and stress is biological through the actions of stress on the major hormones that regulate appetite (leptin and ghrelin). Many spa resorts in France specialise in the treatment of obesity, but no thermal spa currently proposes a specific programme to manage stress in obesity. The ObesiStress protocol has been designed to offer a new residential stress management programme. This thermal spa treatment of obesity implements stress management strategies as suggested by international recommendations. METHODS AND ANALYSIS 140 overweight or obese participants with a Body Mass Index of >25 kg/m2 and aged over 18 years will be recruited. Participants will be randomised into two groups: a control group of usual practice (restrictive diet, physical activity and thermal spa treatment) and an intervention group with stress management in addition to the usual practice. In the present protocol, parameters will be measured on five occasions (at inclusion, at the beginning of the spa (day 0), at the end of the spa (day 21), and at 6 and 12 months). The study will assess the participants' heart rate variability, cardiac remodelling and function, electrodermal activity, blood markers, anthropometric profile, body composition, psychology and quality of life via the use of questionnaires and bone parameters. ETHICS AND DISSEMINATION The ObesiStress protocol complies with the ethics guidelines for Clinical Research and has been approved by the ethics committee (CPP Sud-Est VI, Clermont-Ferrand - ANSM: 2016-A01774-47). This study aimed to highlight the efficacy of a 21-day thermal spa residential programme of stress management in obesity through objective measurements of well-being and cardiovascular morbidity. Results will be disseminated during several research conferences and articles published in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03578757.

Abstract
Objective Work-related stress is a public health issue. Stress has multiple physical and psychological consequences, the most serious of which are increased mortality and cardiovascular morbidity. The ThermStress protocol was designed to offer a short residential thermal spa program for work-related stress prevention that is compatible with a professional context. Methods Participants will be 56 male and female workers aged 18 years or above. All participants will undergo a 6-day residential spa program comprising psychological intervention, physical activity, thermal spa treatment, health education, eating disorder therapy and a follow-up. On six occasions, participants’ heart rate variability, cardiac remodelling and function, electrodermal activity, blood markers, anthropometry and body composition, psychology and quality of life will be measured using questionnaires and bone parameters. Results This study protocol reports the planned and ongoing research for this intervention. Discussion The ThermStress protocol has been approved by an institutional ethics committee (ANSM: 2016 A02082 49). It is expected that this proof of concept study will highlight the effect of a short-term specific residential thermal spa program on the prevention of occupational burnout and work-related stress. The findings will be disseminated at several research conferences and in published articles in peer-reviewed journals. Trial Registration: ClinicalTrials.gov (NCT 03536624, 24/05/2018)

Abstract
Objectives This study sought to examine sex and ethnicity/race differences in the associations between self-esteem, weight status, and trying to lose weight among young adults in the United States. Methods Data were drawn from Wave III (2001/2002) of the US National Longitudinal Study of Adolescent to Adult Health (Add Health public-use sample). Body mass index (BMI) was measured during in-home visits. Weight-loss patterns, self-esteem, and sociodemographics were assessed via self-reports. Logistic regression models were fitted among 4,594 young adults who were aged 21.8 (SD=1.8) years. Results Obesity was associated with relatively poor self-esteem among both African American (P=.007) and White females (P<.006). In comparison to not trying to lose weight, trying to lose weight was associated with poorer self-esteem among normal-weight (OR=1.23, 95% CI=1.03-1.47) and overweight (OR=1.36, 95% CI=1.07-1.72) White females, but not among White females with obesity (OR=1.19, 95% CI=.92-1.55), African American females (OR=.81, 95% CI=.57-1.17), or males (OR=1.00, 95% CI=.88-1.14). Conclusion The decision to lose weight was linked with poor self-esteem solely among normal-weight and overweight White females. African American and White females with obesity presented with relatively poor self-esteem, but their decision to lose weight was not linked with their self-esteem. More studies are needed to understand the psychological mechanism behind the decision to lose weight among White females with obesity, African American females, and males.

Does perceived overweight increase risk of depressive symptoms and suicidality beyond objective weight status? A systematic review and meta-analysis. Clin Psychol Rev 2019; 73:101753.

Abstract
Obesity is associated with a significant disease burden, but whether recognising as opposed to failing to recognise personal overweight is beneficial or detrimental to mental health is unclear. Here we examine the associations between perceived overweight and depressive symptoms and suicidality. A systematic search of three electronic databases yielded 10,398 unique records, from which 32 studies (110 observations) were eligible for inclusion. Pooled odds ratios (OR) and 95% confidence intervals (CI) were calculated for each outcome using random effects meta-analyses and potential publication bias was examined. Perceived overweight was associated with an increased risk of depressive symptoms (OR: 1.42, CI: 1.31, 1.54 p <.0001, N >128,585) and suicidality (OR: 1.41, CI: 1.28, 1.56, p <.0001, N = 133,576) in both cross-sectional and longitudinal studies. The association between perceived overweight and poorer mental health was observed irrespective of study origin, participant age (children vs. adults), gender, and whether or not a person was objectively overweight. The pooled statistical relationship between objective weight status and poorer mental health was attenuated to non-significance when perceived overweight was accounted for, suggesting that the detrimental effect of overweight on mental health is largely dependent on whether or not a person identifies as overweight.

Abstract
Frequent weight loss dieting leads to increased BMI and is associated with eating pathologies. Theoretical models can aid the development of interventions to reduce risk behaviours such as frequent dieting if they are able to adequately account for the target behaviour. The Prototype Willingness Model (PWM) may be able to account for weight loss dieting as this behaviour is often associated with social images. This study explored whether the PWM could predict weight loss dieting status over and above the Theory of Planned Behaviour (TPB). One hundred and ninety-two participants (69% female; mode age 35-44) completed PWM and TPB measures and recorded their height and weight. Males were more likely to be non-dieters than females. Frequent dieters had a higher BMI than non-dieters and rated themselves as more similar to the overweight prototype. Prototype perceptions predicted willingness to eat unhealthy foods alone. Similarity to the overweight prototype predicted weight loss dieting status over and above TPB measures and sex. Further research should explore prototype perceptions in an obese/overweight frequent dieting population as this may be a fruitful direction for developing interventions to reduce weight loss dieting.

Feng X, Wilson A. Does dissatisfaction with, or accurate perception of overweight status help people reduce weight? Longitudinal study of Australian adults. BMC Public Health 2019; 19:619. [PMID: 31113396 PMCID: PMC6530191 DOI: 10.1186/s12889-019-6938-3] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2018] [Accepted: 05/02/2019] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND With studies around the world suggesting a large proportion of people do not recognise that they are overweight (or feel satisfied with being overweight), this fuels the view that such 'misperceptions' need to be 'corrected'. However, few longitudinal studies have examined the consequences of under-perceived weight status, nor over-perceived weight status (when a person feels overweight when they are not) and weight-related satisfaction on trajectories in body mass index (BMI). METHODS Five-year BMI trajectories were examined among 8174 participants in an Australian nationally representative cohort. Each person was classified into groups according to their neighbourhood socioeconomic circumstances, baseline BMI and answers to "how satisfied are you with your current weight?" and "do you consider yourself to be… acceptable weight / underweight / overweight?" Gender-specific multilevel linear regressions were used to examine five-year BMI trajectories for people in each group, adjusting for potential confounders. RESULTS At baseline, weight-related dissatisfaction and perceived overweight were generally associated with higher mean BMI for men and women, regardless of whether they were classified as 'normal' or overweight by World Health Organization (WHO) criteria. Mean BMI did not decrease among people classified as overweight who perceived themselves as overweight, or expressed weight-related dissatisfaction, regardless of where they lived. Among men and women with 'normal' BMI at baseline but expressing weight-related dissatisfaction, mean BMI increased disproportionately among those living in disadvantaged areas compared to their counterparts in affluent areas. Similarly, mean BMI rose disproportionately among people in disadvantaged areas who felt they were overweight despite having a 'normal' BMI by WHO criteria, compared to people with the same over-perceptions living in affluent areas. These differences exacerbated pre-existing socioeconomic inequities in mean BMI. CONCLUSIONS No evidence was found to suggest accurate recognition of overweight or expressing weight-related dissatisfaction leads to a lower BMI. However, there was evidence of an increase in mean BMI among people who felt dissatisfied with, or over-perceived their 'normal' weight, especially in socioeconomically disadvantaged areas. Correction of under-perceptions may not drive weight loss, but circumstances contributing to over-perception and dissatisfaction with weight status may contribute to increased weight gain and exacerbate socioeconomic inequities in BMI.

Abstract
The aim of this research is to study young adults who try to lose weight using only healthful weight-control behaviors. Secondary analyses of the US National Longitudinal Study of Adolescent to Adult Health (Add-Health, N = 3,882) were performed. Females who used only healthful weight-control behaviors had lower self-esteem than females who did not try to lose weight, and less depressive symptoms than females who used unhealthful weight-control behaviors. Data suggested that females who used only healthful weight-control behaviors were at higher risk for gains in body mass index than females who did not try to lose weight. This study adds to the extant literature about weight-control behaviors by highlighting that people who try to lose weight using only healthful weight-control behaviors merit special attention from both scientific and practical points of view.

Jones JM, Schönherr DM, Zaitsoff S, Pullmer R. Changing from the inside out? Examining relationships between overweight identification, dieting behaviours, and body measurements over time. Br J Health Psychol 2019; 24:460-476. [PMID: 30924253 DOI: 10.1111/bjhp.12363] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2018] [Revised: 02/23/2019] [Indexed: 12/18/2022]
Abstract
OBJECTIVE To investigate whether changes in overweight identification were associated with dieting behaviours and body measurements over time. DESIGN Longitudinal study with assessments at three time points: before and twice during (i.e., baseline, 6 months, 12 months) a 1-year self-directed weight loss attempt. METHOD Eighty individuals with overweight or obesity (classified by BMI ≥ 25) reported their personal (i.e., I see myself as overweight), social (i.e., I identify/feel strong ties with other overweight people), and affective (i.e., I am pleased to be overweight) overweight identification; dieting behaviours (e.g., eat less, exercise, eat more fruit and vegetables); and had their body measurements taken (i.e., weight, height, body fat, waist circumference). RESULTS Linear mixed modelling was used to examine between-person differences and within-person changes in overweight identification on dieting behaviours and body measurements over time. Between-person differences mattered for measurements: Higher personal overweight identification was associated with higher BMI, body fat, and waist circumference over time. Higher social overweight identification was associated with higher BMI over time. Within-person changes mattered for behaviours over time: At 12 months, decreases in social overweight identification were associated with increases in a subset of 'Eat Less, Move More' dieting behaviours, but not a subset of 'Healthy' dieting behaviours. At 12 months, decreases in affective overweight identification were also associated with increases in 'Eat Less, Move More' dieting behaviours. CONCLUSION Addressing different aspects of overweight identification and how they change over time, may harness an important psychological pathway to support behavioural change and health irrespective of weight loss. Statement of contribution What is already known on this subject? Psychological factors, such as self-concept clarity and weight stigma, are associated with dieting behaviours and body measurements. Qualitative data suggest that identity change may be tied to dieting behaviours and weight loss. What does this study add? New insights into the nature of another psychological factor, overweight identification, among individuals with overweight and obesity attempting to lose weight. The first quantitative evidence that different aspects of overweight identification, and changes in these aspects of overweight identification over time, influence body measurements and dieting behaviours.

Abstract
The purpose of this study was to determine the associations among body weight status perception, health status, diet quality, and consumption of fruits and vegetables within the adolescent population in the United States. A cross-sectional study was conducted with 1737 adolescents (12-17 years) participating in the Family Life, Activity, Sun, Health, and Eating study, an internet-based survey study sponsored by the National Cancer Institute. Adolescents reported their perception of their weight status, diet quality, health status, and the frequency with which they consumed common fruits and vegetables in a week. Results showed that 62% of the adolescents reported perceiving their weight as "just right," and 10.9%, 22.4%, and 4.7% perceived their weight to be "underweight," "a little overweight," and "very overweight," respectively. Those who perceived their weight status as "just right" also reported their health to be "very good" or "excellent" and that their diet was good. Similarly, adolescents who perceived their weight to be just right consumed significantly more fruits and vegetables than those who perceived their weight as "underweight" or "overweight." Results of this study have important implications for future research on weight and health status, diet quality, and healthy eating behaviors among adolescents.

Abstract
OBJECTIVE To assess the reliability and validity of body weight (BW) and body image (BI) perception reported by parents (in children) and by adolescents in a South American population. DESIGN Cross-sectional study. BW perception was evaluated by the question, 'Do you think you/your child are/is: severely wasted, wasted, normal weight, overweight, obese?' BI perception was evaluated using the Gardner scale. To evaluate reliability, BW and BI perceptions were reported twice, two weeks apart. To evaluate validity, the BW and BI perceptions were compared with WHO BMI Z-scores. Kappa and Kendall's tau-c coefficients were obtained. SETTING Public and private schools and high schools from six countries of South America (Argentina, Peru, Colombia, Uruguay, Chile, Brazil).ParticipantsChildren aged 3-10 years (n 635) and adolescents aged 11-17 years (n 400). RESULTS Reliability of BW perception was fair in children's parents (κ=0·337) and substantial in adolescents (κ=0·709). Validity of BW perception was slight in children's parents (κ=0·176) and fair in adolescents (κ=0·268). When evaluating BI, most children were perceived by parents as having lower weight. Reliability of BI perception was slight in children's parents (κ=0·124) and moderate in adolescents (κ=0·599). Validity of BI perception was poor in children's parents (κ=-0·018) and slight in adolescents (κ=0·023). CONCLUSIONS Reliability of BW and BI perceptions was higher in adolescents than in children's parents. Validity of BW perception was good among the parents of the children and adolescents with underweight and normal weight.

Abstract
To assess the prevalence of weight misperception in American adolescents and its association with diet and physical activity behaviors, Youth Risk Behavior Survey data were utilized for this study. Based on reported and perceived weight, adolescents in the study were grouped into four categories (true negative [52.4%] = normal body mass index [BMI]/accurate weight perception; false negative [11.3%] = high BMI/weight misperception; false positive [11.6%] = normal BMI/weight misperception; and true positive [24.8%] = high BMI/accurate weight perception). Diet and physical activity of adolescents were compared in these categories. A total of 12,016 participants were included in our analysis (74.9% aged 15–17 years, 54.5% Whites, 52% females). Almost a third (31.8%) were overweight and obese, and more than a fifth (22.9%) misperceived their weight (11.6% overestimated and 11.3% underestimated their weight). In a gender-stratified analysis, the odds of avoiding a healthy diet and physical inactivity were higher among those with body weight misperception.

Abstract
OBJECTIVE This study examined secular trends in children's weight-status assessment, measured weight status, and ideal body image and their associations with subsequent changes in BMI, and it explored the differences between sociodemographic groups in China. METHODS Longitudinal data from the China Health and Nutrition Survey of 4,605 children aged 6 to 17 collected between 2000 and 2011 were used and fitted to mixed models. RESULTS From 2000 to 2011, overweight/obesity prevalence increased from 6.5% to 16.8%, but the percentage of children with self-perceived weight status as "fat" remained around 2.0%; 49.0% of children underestimated their weight status at baseline. Self-perceived body image of most participants was tracked during follow-up. Children who perceived themselves as being fat at baseline had a higher BMI increase over time during follow-up than those with an average body image (β [SE] = 0.99 [0.14] kg/m2 per year, P < 0.001). Boys, young children, recent cohorts, and rural children had higher BMI increases than their counterparts. Over time, the thin-body silhouette became more desirable (8.4 percentage points higher, P < 0.001). CONCLUSIONS Chinese children experience a large incongruence between their weight-status assessment, ideal body image, and actual weight status. Health promotion programs should examine their role in assisting children in developing a healthy body image and gaining greater self-motivation toward promoting a healthy lifestyle.

Oldham M, Tomiyama AJ, Robinson E. The psychosocial experience of feeling overweight promotes increased snack food consumption in women but not men. Appetite 2018; 128:283-293.

Abstract
Self-identification of being overweight has been associated with overeating and weight gain in observational studies, irrespective of whether the individual in question is objectively overweight. The aims of the present studies were to examine whether experimentally manipulating the psychosocial experience of feeling overweight impacted on snack food consumption and to identify mechanisms explaining this effect. In Study 1, to manipulate the psychosocial experience of feeling overweight, 120 women wore an obese body suit or control clothing in public or private settings, before consuming snack foods. Wearing the obese body suit resulted in an increase in snack food consumption and this effect was not moderated by whether participants wore the obese body suit in public or in private. In Study 2, we aimed to replicate the effect of the obese body suit on snack food consumption and also examined whether the effect of the body suit on eating behaviour was moderated by participant sex (n = 150; 80 women). Women who wore the obese body suit ate significantly more than women who wore the control clothing, but this effect was not observed in men. Across both studies we examined a number of potential mechanisms that could explain the effect that wearing the obese body suit had on snack food consumption, but did not find supporting evidence. The psychosocial experience of feeling overweight may lead to increased snack food consumption in women, but the psychological mechanism explaining this effect is unclear.
