Does Knowing Hurt? Perceiving Oneself as Overweight Predicts Future Physical Health and Well-Being

Contributions of subjective status to eating behaviors, obesity, and metabolic health across development

Subjective status is the evaluation of one's social or socioeconomic status relative to others. Lower subjective status has been associated with risk of overweight/obesity, poorer metabolic health, and obesogenic food preferences and eating behaviors. However, these findings are predominantly based on studies of adolescents and young adults. This indicates major gaps in knowledge and application of this social determinant of obesity and metabolic health, given that perceived status develops throughout the life course along with food environments and eating habits. Here, we review the relationships that subjective status shares with the outcomes of eating behaviors, obesity, and metabolic health across milestones and periods of development: during the prenatal period, as caregivers who feed children, during childhood (prior to age 10) and from adolescence into emerging adulthood (until mid-20's). For each developmental period, we explore why the period critically contributes to these outcomes and how subjective status may affect eating behaviors and metabolic health. We propose that subjective status contributes to eating/feeding behaviors and metabolic health both within and across developmental periods, such that the effect of low subjective status at an earlier period may contribute to obesogenic eating behaviors and metabolic health in later developmental periods and intergenerationally. The influence of low subjective status on higher body weight may also threaten subjective status later in development through heightened vulnerability to social stressors, such as weight-based stigma. Overall, subjective status may be a broadly influential factor to consider when examining social determinants of obesity and metabolic health across development.

Sense of Purpose in Life and Beliefs and Knowledge of Alzheimer's Disease

OBJECTIVE

A sense of purpose in life is associated with healthier cognitive outcomes, including lower risk of Alzheimer's Disease (ad). The present research examines whether purpose is also associated with beliefs and knowledge of ad.

METHOD

A random subsample (N = 1,187) of community-dwelling participants from the Health and Retirement Study completed a module on self-reported beliefs and knowledge of ad.

RESULTS

Purpose in life was associated with lower perceived threat of ad and greater belief that modifiable factors (e.g., physical activity) decrease risk. Associations were not moderated by experience with ad or depressive symptoms. Purpose was unrelated to beliefs that genetics or stress increase risk or knowledge of ad.

CONCLUSIONS

Individuals with a sense of purpose are less concerned about risk of developing ad and believe modifiable factors reduce risk. These beliefs may support engagement in behaviors that reduce risk and be one psychological pathway through which purpose protects against ad.

Adolescents' Self-Perceived Weight and Metabolic Syndrome

Background and Objective: The aim of this study was to assess the relationships of self-perceived weight with having more metabolic syndrome (MetS) components and the MetS score regardless of body mass index (BMI)-based weight category. Methods: Utilizing data from the Korea National Health and Nutrition Examination Survey 2014 to 2019, weight categories according to BMI and self-perception (underweight, normal weight, or overweight), MetS components defined by the International Diabetes Federation for adolescents, the MetS score, and confounding factors were evaluated in 1441 female adolescents and 1646 male adolescents aged 10 to 18 years. A complex samples general linear model and ordinal regression were used to analyze those relationships. Results: The odds of having more MetS components were 1.67 (95% confidence interval, CI: 1.38-2.03) in adolescents who self-perceived as overweight than in those who self-perceived as normal weight after controlling for sociodemographic and health-related factors and BMI-based weight categories. Compared with adolescents who accurately self-perceived as normal weight (reference group), the odds were 1.48 (95% CI: 1.19-1.84) in those with normal weight, but self-perceived as overweight; 2.90 (95% CI: 1.69-4.98) in those who were overweight, but self-perceived as normal weight; and 9.38 (95% CI: 7.52-11.71) in those who accurately self-perceived as overweight. In relation to the MetS score, similar findings were observed. The combined weight categories had significant interactions with sex and age groups (10-12 years vs. 13-18 years) in those relationships. Conclusions: Regardless of actual weight status, adolescents' self-perceived weight may be a crucial consideration when determining whether or not MetS components may be present.

"I was bullied for being fat in every situation, in every outfit, at every celebration": A qualitative exploratory study on experiences of weight-based oppression in Qatar

Introduction

Weight-based oppression (WBO) has been documented as a widespread phenomenon in Western countries and is associated with a range of psychological, physiological, and behavioral harms. Research on weight-based oppression is largely absent from the Arab region.

Methods

We conducted a qualitative exploratory study using semi-structured in-depth interviews to examine the internalized attitudes, values, and beliefs related to body weight, and experiences of external weight-based oppression of 29 staff, faculty, and students at Qatar University.

Results

Thematic analysis revealed six major themes on the characteristics of internalized WBO, and the nature, timing, source, extent, and impact of external WBO. WBO was regarded as so common in the Arab culture as to be normative, with damaging exposure to WBO beginning in early childhood.

Conclusion

WBO in the Arab region is an important and unrecognized public health issue. Programs to reduce WBO should be developed in all sectors.

Depression and Sexual Stigma Are Associated With Cardiometabolic Risk Among Sexual and Gender Minorities Living With HIV in Nigeria

BACKGROUND

People living with HIV are vulnerable to cardiometabolic diseases. We assessed the prevalence of cardiometabolic risk factors (CMRF) and associations with sexual stigma and depression among sexual and gender minorities (SGM) in Abuja and Lagos, Nigeria.

METHODS

The TRUST/RV368 study enrolled SGM between March 2013 and February 2020. Participants were assessed for depression, sexual stigma, and CMRF. Robust multinomial logistic regression was used to estimate adjusted odds ratio (aORs) and 95% confidence intervals (CIs) for associations of depression, sexual stigma, and other factors with increasing numbers of CMRF.

RESULTS

Among 761 SGM, the mean age was 25.0 ± 6.0 years; 580 (76%) identified as cisgender men, 641 (84%) had ≥1 CMRF, 355 (47%) had mild-severe depression, and 405 (53%) reported moderate-high sexual stigma. Compared with individuals without depression, those with mild (aOR 8.28; 95% CI: 4.18 to 16.40) or moderate-severe depression (aOR 41.69; 95% CI: 9.60 to 181.04) were more likely to have 3-5 CMRF. Individuals with medium (aOR 3.17; 95% CI: 1.79 to 5.61) and high sexual stigma (aOR 14.42; 95% CI: 2.88 to 72.29) compared with those with low sexual stigma were more likely to have 3-5 CMRF. Participants age 25-34 years were less likely to have 3-5 CMRF (aOR 0.41; 95% CI: 0.23 to 0.73) compared with participants age younger than 25 years.

CONCLUSION

CMRF increased with severity of depression and sexual stigma, potentially predisposing SGM living with HIV to cardiometabolic diseases. Integrating interventions that address depression and sexual stigma in HIV care programs for SGM may improve cardiometabolic outcomes.

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

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.

Internalised weight stigma as a mediator of the relationship between experienced/perceived weight stigma and biopsychosocial outcomes: a systematic review

OBJECTIVE

To systematically review studies that have assessed the mediating role of internalised weight stigma on the relationship between experienced/perceived weight stigma and any biopsychosocial outcomes.

METHODS

PsycINFO, PsycExtra, Web of Science, CINAHL, Medline and Embase were systematically searched. Identified studies were double screened (HB and XPG).

RESULTS

Seventeen studies (across 16 articles) met our inclusion criteria (N = 21,172), and almost all studies measured only psychological outcomes (n = 15). Eight studies found consistent evidence for internalised weight stigma as a mediator of the relationship between experienced/perceived weight stigma and disordered eating outcomes. Preliminary evidence was found for the mediating role of internalised weight stigma on the relationship between experienced/perceived weight stigma and body shame, body dissatisfaction, exercise behaviour, healthcare experiences and behaviours, bodily pain and parental weight talk. However, the findings were inconsistent for depression and anxiety, although only two studies reported these.

CONCLUSION

This review provides preliminary evidence for internalised weight stigma as an intervening variable in the relationship between experienced/perceived weight stigma and adverse health outcomes. Results suggest that there are potential benefits of interventions addressing internalised weight stigma to improve health outcomes. However, these findings must be considered in the context of the psychometric limitations of the Weight Bias Internalisation Scale, which was used in all but one study.

Association of body image dissatisfaction, behavioral responses for healthy eating, and cardiovascular health in African-American women with overweight or obesity: A preliminary study

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.

Weight-related teasing is associated with body concerns, disordered eating, and health diagnoses in racially and ethnically diverse young men

Research suggests that weight-related teasing is associated with body concerns and disordered eating in male and female adolescents and women. Yet, little is known about these associations for young men with diverse racial and ethnic identities. This study examined the association of weight-related teasing frequency and distress with body concerns, loss of control (LOC) eating, dietary restraint, and history of psychiatric and medical diagnoses in racially and ethnically diverse young men. Racial and ethnic identity was examined as a potential moderator. Participants (N = 1,069; 18-30 years; M_age = 24.1 ± 3.6 years) completed an online survey and reported on general demographics; weight-related teasing; body concerns; LOC eating frequency in the last 28 days; dietary restraint; and history of psychiatric and medical diagnoses. All models adjusted for BMI, income, education, and history of psychiatric diagnoses (when not the dependent variable). Both weight-related teasing frequency and distress were significantly and positively linked with all dependent variables, and these associations did not significantly vary by racial and ethnic identity. These findings suggest that, much like in prior research with adolescents and women, experiences with weight-related teasing are associated with body concerns, disordered eating, and poorer health in racially and ethnically diverse young men, regardless of body size.

Treatment Outcomes and Trajectories of Change in Patients Attributing Their Eating Disorder Onset to Anti-obesity Messaging

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.

Gender differences in factors associated with body weight misperception

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.

Self-perception of overweight and obesity: A review of mental and physical health outcomes

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.

Association of depression and obesity is mediated by weight perception

This study investigates whether the association between obesity and depression is mediated by the perception of body weight and verifies the combined effect of being obese and having a self-perception of being fat on depression in a population-based sample of 1238 individuals. Weight perception mediated the association between depression and obesity in 39.3 percent of participants. In stratified analysis, mediation occurred in the following groups: non-single, those with more schooling, non-alcohol abusers, non-smokers, and those who did not engage in physical activity. Being obese and having a self-perception of being fat produced a potentiating effect, significantly increasing the likelihood of depression.

Does perceived overweight increase risk of depressive symptoms and suicidality beyond objective weight status? A systematic review and meta-analysis

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.

Perceived Weight Discrimination Mediates the Prospective Association Between Obesity and Physiological Dysregulation: Evidence From a Population-Based Cohort

Obesity is thought to cause ill health because of the biological strain that excess fat has on physiological function. We tested an alternative explanation in a population-based sample of 3,609 older English adults-that the pervasive discrimination experienced by individuals with excess weight may in part explain why obesity is associated with subsequent multisystem physiological dysregulation, measured via clinical indicators of cardiovascular, metabolic, and immune function. We found that both obesity and perceived weight discrimination predicted an increase in physiological dysregulation from baseline to follow-up 4 years later. Perceived discrimination because of body weight experienced by individuals with obesity explained more than one quarter of the prospective association between obesity and a deterioration in biomarkers of health status. These findings highlight the possibility that the stigma experienced by individuals with obesity may play an important role in explaining the obesity-related disease burden.

Does dissatisfaction with, or accurate perception of overweight status help people reduce weight? Longitudinal study of Australian adults

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.

The relationship between intuitive eating and body image is moderated by measured body mass index

Intuitive eating (IE) is a pattern of adaptive eating that has been associated with positive psychosocial and physical factors (e.g., positive body image, lower body mass index; BMI). However, BMI has also been negatively associated with body image. Our goal was to evaluate whether IE is uniquely associated with body image, independent of objective weight status (measured BMI). Further, as a secondary aim, this study analyzed potential moderators (BMI, sex, race-ethnicity) in the IE-body image relationship. Data from 136 adults (34 ± 15 years old, 74% female, 56% Caucasian) were analyzed. BMI was objectively measured in-lab. IE was measured with the Intuitive Eating Scale-2. Body image was measured as a Body Concern composite created using the Eating Disorder Examination-Questionnaire (EDE-Q 6.0) Weight and Shape Concern subscales. Demographic factors and covariates were measured via self-report. Regressions revealed that, after controlling for BMI and covariates, Total IE was uniquely associated with Body Concern (β = -0.463, p < .001), as were two of the IE subscales: Unconditional Permission to Eat (Unconditional Permission; β = -0.320, p < .001) and Eating for Physical Rather than Emotional Reasons (Physical Reasons; β = -0.408, p < .001). BMI was also found to be a significant moderator between IE and Body Concern for Total IE (b = 0.071, p = .017), Unconditional Permission (b = 0.067, p = .001), and Physical Reasons (b = 0.038, p = .021), with the negative association between IE and Body Concern being strongest for healthy weight individuals. Greater IE was associated with lower body image concern across the weight spectrum, though this relationship was strongest for healthy weight individuals and attenuated as BMI increased.

How and why weight stigma drives the obesity 'epidemic' and harms health

BACKGROUND

In an era when obesity prevalence is high throughout much of the world, there is a correspondingly pervasive and strong culture of weight stigma. For example, representative studies show that some forms of weight discrimination are more prevalent even than discrimination based on race or ethnicity.

DISCUSSION

In this Opinion article, we review compelling evidence that weight stigma is harmful to health, over and above objective body mass index. Weight stigma is prospectively related to heightened mortality and other chronic diseases and conditions. Most ironically, it actually begets heightened risk of obesity through multiple obesogenic pathways. Weight stigma is particularly prevalent and detrimental in healthcare settings, with documented high levels of 'anti-fat' bias in healthcare providers, patients with obesity receiving poorer care and having worse outcomes, and medical students with obesity reporting high levels of alcohol and substance use to cope with internalized weight stigma. In terms of solutions, the most effective and ethical approaches should be aimed at changing the behaviors and attitudes of those who stigmatize, rather than towards the targets of weight stigma. Medical training must address weight bias, training healthcare professionals about how it is perpetuated and on its potentially harmful effects on their patients.

CONCLUSION

Weight stigma is likely to drive weight gain and poor health and thus should be eradicated. This effort can begin by training compassionate and knowledgeable healthcare providers who will deliver better care and ultimately lessen the negative effects of weight stigma.

Weight Perception, Weight Stigma Concerns, and Overeating

OBJECTIVE

Perceiving one's own weight status as being overweight is a likely motivation for weight loss. However, self-perceived overweight status has also been found to be associated with overeating and weight gain. This study examined whether weight stigma concerns explain why individuals who perceive their weight status as overweight are at increased risk of overeating.

METHODS

We conducted two survey studies of United States adults (N = 1,236) in which we assessed whether weight stigma concerns explain the cross-sectional relationship between perceived overweight and overeating tendencies.

RESULTS

Across two studies, the cross-sectional relationship between perceived overweight and overeating tendencies was in part explained by weight stigma concerns. Participants who perceived their weight as "overweight" reported greater weight stigma concerns than participants who perceived their weight as "about right," and this explained 23.3% (Study 1) to 58.6% (Study 2) of the variance in the relationship between perceived overweight and overeating tendencies.

CONCLUSIONS

Weight stigma concerns may explain why perceiving one's own weight status as overweight is associated with an increased tendency to overeat.

Body weight perception, disordered weight control behaviors, and depressive symptoms among Korean adults: The Korea National Health and Nutrition Examination Survey 2014

BACKGROUND/ PURPOSE

Despite emerging evidence suggesting harmful influences of accurate weight perception on psychological health among individuals with obesity, little is known about the association in Asian populations. The aim of this study was investigate the association between body weight perception and depressive symptoms among Korean adults, and potential differential associations across gender.

METHODS

We used data from the sixth Korea National Health and Nutrition Examination Survey in 2014, comprising 3,318 female (n = 1,876) and male (n = 1,442) participants, aged 19-65 years, with no history of depression and a body-mass index (BMI)> = 18.5kg/m2. Depressive symptoms were measured by the Patient Health Questionnaire-9 Korean version. Weight perception patterns were categorized by comparing self-perceived and objectively measured weight status. Gender-stratified four-level multilevel linear models adjusted for age, BMI, menopause, education, income, marital status, urbanicity, chronic conditions, exercise, smoking, and alcohol use. Subgroup analyses were performed across BMI category.

RESULTS

Among women with obesity, those who underperceived their weight status reported fewer depressive symptoms compared to those who accurately perceived their weight status (β = -1.25, p<0.05). Among women with normal weight, those who overperceived their weight status reported more depressive symptoms compared to those who accurately perceived their weight status (β = 1.00, p<0.05). The same associations were not found in men.

CONCLUSION

Awareness-oriented strategies for obesity prevention and weight management focused on providing information on weight status may need to consider unintended consequences of accurate weight perception on mental health among individuals with obesity, particularly among women.

Mechanisms underlying weight status and healthcare avoidance in women: A study of weight stigma, body-related shame and guilt, and healthcare stress

Studies show that women with high BMI are less likely than thinner women to seek healthcare. We aimed to determine the mechanisms linking women's weight status to their healthcare avoidance. Women (N = 313) were surveyed from a U.S. health-panel database. We tested a theory-driven model containing multiple stigma and body-related constructs linking BMI to healthcare avoidance. The model had a good fit to the data. Higher BMI was related to greater experienced and internalized weight stigma, which were linked to greater body-related shame. Internalized weight stigma was also related to greater body-related guilt, which was associated with higher body-related shame. Body-related shame was associated with healthcare stress which ultimately contributed to healthcare avoidance. We discuss recommendations for a Weight Inclusive Approach to healthcare and the importance of enhancing education for health professionals in weight bias in order to increase appropriate use of preventive healthcare in higher weight women.

The Cardiometabolic Burden of Self-Perceived Obesity: A Multilevel Analysis of a Nationally Representative Sample of Korean Adults

Emerging evidence has shown that self-perception of overweight/obese status is associated with unfavorable cardiometabolic outcomes, above and beyond actual body weight. Given the lack of research among Asian populations, we examined the association between weight perception and metabolic syndrome (MetS) and cardiometabolic risks among Koreans. Data from the 2010–2015 Korea National Health and Nutrition Examination Survey, including women (N = 12,181) and men (N = 9,448) aged 19–65 years, were analyzed. Weight status perception was measured by participants’ self-evaluation of their body size (“very/slightly obese,” “normal,” and “very/slightly thin”). Overall, 23.2% of women and 28.7% of men had MetS. Our cross-sectional multilevel logistic analyses showed a significant positive association between self-perceived obesity (vs. perceived normal weight) and MetS, independent of BMI and sociodemographic/behavioral/medical conditions, with a stronger association detected among men (OR = 1.38, p < 0.05) than women (OR = 1.22, p < 0.05), confirmed by a statistically significant interaction. Additionally, perceived obesity was associated with high blood pressure (OR = 1.27, p < 0.05) and high triglycerides (OR = 1.38, p < 0.05) among men and low high-density lipoprotein cholesterol (OR = 1.15, p < 0.05) among women. While further prospective research is needed, our findings suggest that perception of being obese may be an unfavorable indicator of cardiometabolic health among Koreans regardless of actual body weight.

A systematic review of the relationship between weight status perceptions and weight loss attempts, strategies, behaviours and outcomes

It is commonly assumed that a person identifying that they are 'overweight' is an important prerequisite to successful weight management. However, there has been no systematic evaluation of evidence supporting this proposition. The aim of the present research was to systematically review evidence on the relationship between perceived overweight and (i) weight loss attempts, (ii) weight control strategies (healthy and unhealthy), (iii) weight-related behaviours (physical activity and eating habits), (iv) disordered eating and (v) weight change. We synthesized evidence from 78 eligible studies and evaluated evidence linking perceived overweight with outcome variables separately according to the gender, age and objective weight status of study participants. Results indicated that perceived overweight was associated with an increased likelihood of attempting weight loss and with healthy and unhealthy weight control strategies in some participant groups. However, perceived overweight was not reliably associated with physical activity or healthy eating and was associated with greater disordered eating in some groups. Rather than being associated with improved weight management, there was consistent evidence that perceived overweight was predictive of increased weight gain over time. Individuals who perceive their weight status as overweight are more likely to report attempting weight loss but over time gain more weight.

Parental perception of child weight and inflammation: Perceived overweight is associated with higher child c-reactive protein

Self-perceived overweight and weight discrimination are associated with inflammation in adulthood. We test whether there is an intergenerational association of parent perception of child overweight on higher levels of child c-reactive protein (CRP), a marker of inflammation implicated in stress. Data were from the National Health and Nutrition Examination Survey 2005-2014 (N=4988). Parents reported their perception of their child's weight; CRP was assayed from children's blood samples. Children whose parents perceived them as overweight had higher CRP levels than children who were perceived about the right weight; perceived underweight was also associated with higher CRP (F(2,4977)=9.23, p<.001). These associations were independent of the child's objective weight status and waist circumference and held when the sample was limited to children with objective overweight and obesity. These results suggest an intergenerational transfer of the psychological perception of body weight from parents to the inflammatory health of their child.
