Introduction
The global prevalence of overweight and obesity in children and adolescents has increased from less than 1% in 1975 (11 million) to almost 14% (124 million) in 2016 [1,2], representing one of the most serious health problems, with features of pandemic, of the 21st century. These figures continue to rise at a worrying rate, especially in developing countries such as Colombia. The problem lies, above all, in the fact that overweight and obese children maintain this trend in adulthood, which increases the chances of developing, at an early age, Chronic Non-Communicable Diseases (NCDs) such as diabetes and cardiovascular conditions [2].
Evidence [3-8] shows that the increased prevalence of NCDs is associated with unhealthy lifestyles, characterized by sedentarism, inadequate diet, the daily use of information and communication technologies that keep users inactive and the habits acquired since childhood that are maintained into adulthood.
Overweight and obesity in children and adolescents have been defined by the World Health Organization (WHO) as follows:
Overweight is equal to the Body Mass Index (BMI) for age and gender added up to more than one standard deviation above the median established in infant growth patterns, and obesity is equal to BMI for age and gender plus more than two typical deviations above the median established in infant growth patterns [2 p4].
Today, many children grow up in an obesogenic environment that comes to favor and encourage weight gain, mostly because of the availability, affordability and commercialization of unhealthy foods and low energy consumption due to lack of physical activity and sedentary lifestyle, as the time children spend in front of a screen has increased [9,10].
A child’s biological and psychosocial responses to an obesogenic environment may be affected by socio-cultural determinants prior to birth, increasing, as a matter of course, the numbers of obese children. It is therefore necessary to change unhealthy dietary patterns and increase physical activity, while these socio-cultural determinants must be modified [11,12].
Fortunately, the conditions of overweight and obesity are largely reversible, so prevention work is needed that includes education in healthy lifestyles, increase and incentive of physical activity in all school-age children and teaching them proper eating habits. It is also necessary to choose healthy foods for infants and children under the age of five, as it is known that food preferences are established from an early age in the life cycle [2,13].
Lack of education and knowledge about adequate and balanced nutrition, added to the difficulties in the availability and accessibility of healthy food and the promotion, in mass advertisements, of unhealthy drinks and food for children and families contribute to aggravate this problem. In the conditions of globalization, digitization and urbanization that the world is living today, there are few possibilities for physical activity, that would allow the energy expenditure necessary to have an adequate weight [2,3,6].
In Latin America, the prevalence of overweight and obesity also shows figures that reflect the severity of the situation. In 2014, this prevalence was 7.1% in children under 5 years of age. In children between the ages of 5 and 12, it reached standards between 18.9% and 36.9% and, in adolescents, it was 16.6%-35.8%; that is, from 20% to 25% of the total population of children and adolescents in Latin America suffers from overweight and obesity [14].
Mexico ranks first worldwide in childhood obesity (26% for both genders, 4.1 million children between 5 and 12 years) and is second in obesity in adults (the first place belongs to the United States) [15,16]. In Colombia, according to the Third National Survey of the Nutritional Situation [17], the prevalence of overweight and obesity was 24.4% in children between 5 and 12 years of age, the problem being more serious among the population with better socioeconomic situation.
Excess weight in childhood and adolescence represents physiological and biomedical problems and psychosocial consequences and risk factors, such as depression, lower self-esteem, bullying by peers, difficulties in socialization, being associated with negative stereotypes and the development of stigmatizing prejudices and discrimination in the social environment [18-23].
The stigmatization of overweight or obese children and adolescents has been recognized in Western cultures and can range from verbal jokes, such as insults, derogatory comments and mockery, to physical harassment, reflected in blows, kicks or shoves, which, spread over time, can lead to victimization and discrimination. This can result in social exclusion, being ignored or avoided, or becoming the target of rumors, because stigma can arise in subtle ways or manifest itself openly [24], and seems to have increased in today’s society [18-19,24-25].
Stigma is defined as a deeply discrediting attribute, mark or characteristic (real or supposed), usually based on a physical difference or deviation from the social norm, such as a physical deformity, character flaws or aspects related to family history [20,21,26-28], which penalizes the person in his or her social status.
For Goffman [29], there is nothing in the attribute itself that makes it stigmatizing, because an attribute is neither honorable (positive) nor ignominious (negative). What is important is the meaning that the social environment gives to this attribute, by linking it with negative stereotypes. Therefore, stigma is a social construct [22,29,30], a conjunction between the mark, attribute or characteristic and the social stereotypes associated with these, which create a socially devaluative identity, which leads to the loss of status of those who possess it [30].
As for overweight and obesity, Ozuna et al. [19] define stigma as the rejection and social denigration suffered by people who do not meet the prevailing social standards regarding weight and body shape and image, producing negative attitudes, stereotypes, prejudices and discrimination. This of course generates psychosocial affections of great consideration, which add to the health problems that these patients already suffer [19,22,25,31].
Holzemer et al. [32] identified three types of stigma: stigma received, stigma by association and self-stigma, which is the result of internalizing stigmatizing behaviours observed in the community and may relate to other types of stigma and prejudice present in society, such as those associated with ethnicity, economic income, social classes or gender, among others [31-33].
Prejudice, stereotypes, stigma and discrimination are interrelated and mutually reinforcing. It could be said that stigma is the basis of discriminatory actions and behaviour (staging of stigma) and, in turn, is the product of prejudice and stereotypes, that generate actions or omissions in people that harm or deny services or rights to victims [34-39].
On the other hand, it is also important to consider the frustrations with the difficulties of adherence to treatment when a treatment is followed and weight loss is not achieved, and the psychopathological consequences of trying to sustain a diet (effective or not). Children and adolescents in this situation often feel guilty and ashamed and are criticized for their "failure" by their family members, peers and health professionals [8].
Given this scenario, some large-scale efforts have been generated to provide health interventions in areas such as effective nutrition and physical activity, aimed at children and because the school represents the ideal environment for a more rational and rapid strategy that will lead to a greater coverage of this population [40-42]. Evidence [3-8] is currently available to demonstrate the feasibility and effectiveness of educational interventions that are sustainable if regularly integrated into the school curriculum [6].
In countries such as Colombia, there is a normative and political framework that favors the feasibility of such interventions and makes them enforceable (Article 12 of Law 115 of 1994, 2006; Law 1355 of 2009; Law 2120 of 2021), because they advocate training for comprehensive prevention, the promotion and preservation of health and body hygiene, physical education/activity, recreation, sport and adequate use of leisure time, and the promotion of healthy eating environments.
For these reasons, the “Program Generación Vida Nueva" (PGVN) [8] emerged in 2015 as a strategy in the District of Barranquilla, Colombia, to address obesity and overweight in children from 5 to 12 years in the school environment and to promote healthy lifestyles. The PGVN aims to create interventions integrated with the daily educational practice of the 17 participating primary schools (10,000 students) and has developed annual anthropometric activities [43], including the measurement of the Body Mass Index (BMI) and medical checks of overweight or obese children.
By carrying out anthropometric measurements that confirm overweight or obesity, these children have felt discriminated against by their peers and feel different when invited to follow-up and medical, nutritional, physical activity and psychosocial interventions, necessary for their condition. Parents have also said that their sons and daughters bring home this sense of social stigma and have communicated it to schools. Teachers have also noticed the discomfort of these children during classes.
However, at least from this context, there are no known research approaches or studies that show the reality of stigmatization and stereotypes that overweight and obese children are subjected to. The PGVN’s work has shown very accurately the prevalence and comorbidities of this problem, but the psychosocial dimensions are just a reference. In fact, there is little work on stigmatization in Colombia and Latin America.
As a way of approaching this reality, it is proposed to carry out a systematic review that allows knowing the state of research regarding the levels of stigma and discrimination of overweight and obese children in the context of primary schools. The fundamental purposes of this work are two: First, to assist in the planning of research of a quasi-experimental or experimental nature that sensitizes the academic community to the incidence of stigmatization on the mental health of individuals and specifically children; second, appropriate theoretical and practical elements for the design of accompanying and intervention strategies, which will make it possible to face this reality, suffered by many children and adolescents, and thus prevent the emergence of NCDs, such as diabetes, in early stages of their development.
Several hypotheses accompany this systematic review. The first is that overweight and obese children do suffer to some extent from stigmatizations, many of which occur in the educational systems they are part of and are generated by classmates, but also by teachers themselves. The second hypothesis is that the stigmatization suffered by these children has different levels: there is social stigmatization, which is when it comes from some of their peers; institutional stigmatization, the derivative of schools; self-stigmatization, which is that stigma that the same child infringes himself or herself, that is, "As I am fat, then I am clumsy". Finally, one last hypothesis is that stigmatization and its effects can be reduced through educational strategies that can be established within curricular or extracurricular processes.
As a further goal, the research team aims to conduct meta-analytic studies to determine the effects of overweight and obesity in children and youth population in a variety of psychosocial dimensions, including self-concept, self-esteem, learned helplessness, self-discrimination, supported, of course, by statisticians used from controlled studies of the cause-effect type. However, the current state of research, in these subjects, did not allow finding evidence of such studies with sufficient statistical strength to consolidate a meta-analysis.
Results
The search in the PubMed/Medline, ERIC, Google Scholar (in English and Spanish) databases yielded 1709 articles. After eliminating duplicates and excluding by titles, there were 407 articles with which summaries and complete articles were read to verify the inclusion criteria. Then, 376 studies were excluded for the reasons described in Figure 1 and 31 articles were included in the study.
The 31 studies covered a population of 24935 children, of whom 49.67 per cent were girls and 50.33 per cent were boys. The mean age ranged from 7.5 to 11.9 years. There was little information, in the studies, on the social extraction of the sample and some did not report on the school grades attended by the children, although these were generally primary school grades. Most of the studies were of a cross-sectional type (14/31), followed by longitudinal studies of a prospective type (5/31) and studies of a correlative type (5/31). We found 3 Randomized Clinical Trials, 1 qualitative study, 1 mixed study (qualitative-quantitative) and 1 inter and intra-subject experimental study. Details and summaries of the results of the included studies are available in the Appendix.
Most of the research was done in the United States (10/31), 3 in Ireland, 3 in Germany, 2 in Spain and 1 in countries such as Italy, Canada, Greece, Hungary, Australia, China and Cuba. The journals that have published such studies mostly belong to the area of health (especially pediatric or obesity; 30/31) and only 1 to the area of education.
Characteristics of social stigma for overweight and obesity in school-age children
Most of the studies (96%) included in this review (30/31) provided information on the characteristics of social stigma for overweight and obesity in school-age children. In terms of content analysis, it was found that children, during primary education, are able to stigmatize their peers and show their favoritism towards certain peers [46]. Overweight and obesity are highly stigmatized conditions in Western society and the message is conveyed, especially to children and women, that thinness means power, success, beauty and self-efficacy [47].
It is for this reason that overweight or obese children are more likely to be stigmatized in an individual or social context compared to their normal weight peers [46-59], which is why they also suffer from bullying [54].
The social stigma of overweight and obesity is frequent and its prevalence among certain age groups and populations, such as school-age children, makes this population more vulnerable [45,56]. Bullying resulting from this stigma affects the well-being, quality of life and academic performance of overweight or obese children in primary school, and the consequences may be lifelong [54].
The levels of evidence of the studies are low (only 1 study was an ACE), so statistics and effect sizes could not be presented, and the variables measured were described, which were mostly performed in a qualitative way.
Weight labelling
29% of the studies included in this review worked with the weight labeling variable. According to the longitudinal study conducted by Hunger and Tomiyama [59], in which anthropometric and weight labelling measurements were made, 57.9% of the participants reported being labeled "fat". Baseline BMI and labeling condition correlated moderately with this result (r = 0.41, P = less than 0.001). In the evaluation of this association 10 years later, labeling remained a significant predictor of overweight or obesity with an OR = 1.66. The OR was 1.62 when it was family members who labeled and 1.40 when it came to other people.
Mustillo et al. [60] found a link between psychological distress experienced from 18 to 21 years and parental and peer labeling due to the stigma of obesity from 9 to 10 years old, especially in white children.
On the other hand, implicit and explicit attitudes associated with negative attitudes towards overweight or obese children are quite widespread and have been shown to be resistant to interventions. These weight-related attitudes were studied in the cross-sectional research of Hutchinson and Mueller [61], where findings indicate that implicit and explicit attitudes towards overweight and obesity are significantly correlated. It was also found that implicit attitudes associated with weight tended to be higher in older children.
Social stigma of overweight and obesity and school harassment
About 23% of the included studies treated school harassment among their variables. For example, the cross-sectional study by Lumeng et al. [52] investigated the relationship between social stigma and harassment as reported by the child, the child’s mother and the teacher. It was noted that 33.9 per cent (teacher’s report), 44.5 per cent (mother’s report) and 24.9 per cent (child’s report) of children had been harassed. We found a significant independent relationship between being obese or overweight and being harassed with a probability ratio of 1.63, 95% CI, 1.18-2.25, after adjusting it according to school grade, gender, race and family income.
On the other hand, the research by Madowitz et al. [62], which performed logistic and linear regressions to evaluate the relationship between the variables of harassment, depression and unhealthy weight control behaviors, found that overweight or obese children who are bullied have significantly higher levels of depression (B=6.1; SE=2.3) and are 5 times more likely to have unhealthy weight management behaviors (OR=5.1, 95% CI, 1.5-17.4) and that teasing associated with excess weight is related with negative psychosocial factors in these children.
The only Latin American study that was part of this review [63], conducted in several municipalities in Cuba, found that Cuban schoolchildren do not accept their overweight or obese peers contextually. In Cuba, obese children are stigmatized to a lesser degree than in America or New Zealand (where the same type of study was conducted), but stigmatization does occur anyway. Children of both genders with little control over their eating habits suffer the greatest consequences of bullying and peer rejection.
Social stigma of overweight and obesity on the part of peers
About half of the studies (48%, 15/31) considered the social stigmatization of overweight and obesity by peers. Regarding the perception of obesity by children and adolescents, in the qualitative study by Amini et al., children of both sexes stated that they did not like overweight and obesity and described them as excess fat and body weight, overeating, devouring, a condition that makes people lazy, ugly and heavy [64]. For their part, obese children considered obesity as a disease or cause of other diseases such as cancer, a stunting; something that will give a short life, that means having deprivations, a barrier to exercise, be agile and for routine activities, for social activities such as public speaking and for progress in life. Overweight or obese children are perceived as objects of ridicule, who are easily angered by taunts, and, adults and peers, expect an obese child to work and try harder because he or she "is strong".
The study by Brixval et al. [51] found that overweight students (OR 1.75, CI 95%, 1.18 -2.61) or obese students (OR 1.98, CI 95%, 0.79-4.95) were more exposed to bullying than their normal weight peers. Likewise, a greater internalization of weight bias (not properly calculating one’s weight considering that one has less weight than real) was associated with more teasing and harassment by peers and lower self-esteem.
The prospective study of Gmeiner and Warschburger [57] found that a considerable weight of the child, the female sex, experiencing teasing, a significant dissatisfaction with own weight, giving great importance to the figure and appearances, high depression scores and low parental education, are predictors of an internalization of Weight bias (a form of self-stigma in which the individual applies negative weight-based stereotypes against him or herself and blames him or herself for his or her condition regardless of actual weight) [63-66].
Likewise, in the research conducted by Kornilaki [67], in which two characters were showed, one with positive qualities (thin figures) and the other with negative (obese figures), to measure weight bias, it was observed that actual body size affected the accuracy of perceived body size: while normal weight children accurately identified their physical proportions, most overweight or obese children tended to underestimate their own weight. However, it was also found that perceived weight accuracy improved with age.
In the cross-sectional study by Gigirey et al. [68], conducted in Santiago de Compostela, Spain, it was found that a rejection of peers who are overweight or obese is produced. In addition, Olsen’s research [55] found that 59% reported their peers teasing their weight and 49% reported that their parents did the same, and these taunts, in turn, are related to eating problems ("binge eating") for emotional reasons.
The longitudinal "Growing Up" study, conducted in Ireland [69], found that children with a BMI indicating overweight or obesity were significantly more likely to be victimized and discriminated against compared to normal weight children. Weight-based teasing was found to be correlated with an increase in weight gain of the victims (33%), compared with peers who did not report it [70] and these experiences can increase the risk of health problems, including weight gain and bullying.
The research by Olsen et al. [55] found that obese children were considered less often as "best friends" and had a lower rating in the level of acceptance by their peers. In addition, they were described by their classmates as more socially withdrawn, with less leadership, with more aggressive-disruptive behavior, less physically attractive, more sick, tired and absent, less athletic and their relationships were different from those of normal weight peers.
Papp and Túry’s research [71] found that there are cultural differences in attitudes towards obesity and that it is worth continuing to explore these differences. Likewise, the study by Bird et al. [72] found that there were improvements in girls' body satisfaction, in issues related to appearance, eating behaviors and knowledge of the subject of the intervention; besides that, there was a significant reduction of cultural appearance ideals. However, none of these changes remained in follow-up 3 months after the intervention.
Body image and social stigma of overweight and obesity
The body image variable was considered by a large percentage of the studies (78%). Brixval et al. [51] found that body image mediates the associations between weight status and exposure to harassment in both boys and girls. Likewise, the study by Damiano et al. [73] found that 34% of overweight or obese girls reported a moderate level of dietary restriction and that most girls were satisfied with their body image, although half of them showed an internalization of the ideal of the slim figure. In addition, exposure to mass media and social media and talk about appearance were found to be the strongest predictors of dietary restriction. It is necessary to consider that the precision about the own weight improves with age, that is, the more children grow, the more they calculate with greater precision their own weight, despite that this indicates overweight or obesity. However, it was also observed that more than half of overweight or obese children stigmatized fat figures or appearances as if they represented other children and not them.
Jendrzyca and Warschburger [74] conducted a study to explore the role of social weight stigma in body image dissatisfaction and its influence on eating behaviors and found that weight status predicted dissatisfaction with one’s own body image, while weight stigma did not have a direct effect on eating disorders.
According to the study by McCormack et al. [53], 40% of overweight or obese children reported that their peers mocked them and 36% that their relatives too did, resulting in lower body satisfaction among children subjected to teasing and harassment compared to children who were not bullied. Research by Reulbach et al. [70] concluded that body image is more associated with victimization, discrimination and bullying than with objective weight classification based on BMI.
In the randomized clinical trial conducted by Ross et al. [75], to measure the effectiveness of the "Y’s Girl" body image program, the results showed that the girls who received the intervention reported an improvement in body image and self-esteem. Therefore, children who grow up with cultural influences that denigrate overweight and favor thinness as an ideal body image, associate people with overweight or obesity, explicitly or implicitly, with a few negative characteristics that have nothing to do with weight [74].
Moreover, in their study, Guardabassi and Tomasetto [76] decided to investigate whether the threat of negative stereotype associated with excess weight influences working memory. Working memory was found to decrease as BMI increased, showing that the threat of the stereotype of being less intelligent because of overweight or obesity arises at early ages and can influence working memory performance.
Self-stigma of overweight and obesity
About 31% of the studies examined self-stigma. The study by Chan et al. [77] found that overweight and obese children have a higher level of self-stigma and this, in turn, was related to more mental health problems, that is, overweight or obesity condition and victimization interact to influence the ratings of kindness and negative emotions. Thus, the state of self-victimization of children influences the ratings of social attraction, kindness and negative emotions.
For example, Olsen et al. [55] found that overweight/obese children perceive themselves more negatively compared to their normal weight peers and that age, gender, race and perceived responsibility affect attitudes towards an overweight or obese companion. The study by Wong et al. [78] found that overweight or obese children develop weight-related self-stigma (p= 0.,003), and tend to have poor quality of life in relation to health, compared to normal weight children, which means that the experience of teasing and self-stigma is more important than the actual state of weight.
Differences between boys and girls
Seventy-nine per cent of the studies considered differences between boys and girls. Several studies [44,45,55,72] were found in which the social stigma of overweight and obesity occurs more frequently among girls than among boys. Also, some research [61,72] showed that the associations between weight status, stigmatization for excess weight, dissatisfaction with body image and eating behaviors present differences according to gender, that is, girls stigmatized obese or overweight peers less than boys.
Some aspects of the prevention of social stigma due to overweight and obesity in school-age children
Several studies found that children included as factors of obesity prevention physical exercise, decrease food consumption in general, increase the consumption of fruits and vegetables, abstain from eating foods rich in calories, limit the time to watch TV and sleep, eat a light dinner and a hearty lunch, visit a nutritionist or dietitian and have a strong will [62,72].
Discussion
The findings indicate that overweight and obese children are more likely to be victims of social stigma and harassment, although this is more physical than relational, and intimidation and victimization on the part of their normal weight peers [44,46-55]. There are several studies [79-80] which confirm the aforementioned, giving rise to psychosocial problems in both the short and the long term [81].
The Strauss study [80] showed that a decrease in self-esteem in overweight or obese children can result in loneliness, sadness, nervousness and depression, and can affect the school performance of these children [75,79,81,82]. Previous experiences (negative perceptions) with overweight or obese individuals or family members can affect children’s attitudes and are important if a negative psychosocial impact on them is to be reduced [67].
These children have problems with their own body image and there's a possibility that they develop eating disorders [82]. Being labeled as "too fat, dumb, dirty, ugly, sloppy, unreliable, lazy, and a liar" during the childhood years can lead to increased chances of presenting overweight or obesity a decade later [57] because it augments obesogenic stress that triggers negative coping behaviors such as overeating [81].
The child labeled as "fat" is affected in his or her identity and this determines his or her behaviors, producing negative feelings that, in turn, lead him or her to overeat, falling into a vicious circle difficult to overcome and presenting a greater risk of suffering isolation, taunts, intimidation, insults, to the point of physical and not just relational aggression [81].
It is necessary to recognize the importance of using anthropometric measurements, such as BMI, from very early ages, to identify overweight/obese children and propose effective interventions to prevent and treat their excess weight, including psychosocial factors, such as the social stigma of this condition [79,83], and to develop positive coping behaviors and education in healthy lifestyles.
On the other hand, the review by Bautista Diaz et al. [83] found that within the family and in the school, health services and work environments, overweight discrimination is promoted and accepted on a daily basis, and as if it were normal. Instead, these should be environments from which social support and understanding would be expected.
The internalization of attitudes of rejection towards obese or overweight people is established from very early ages, where the family environment influences in this direction, in addition to the school environment, through the relationship with peers. In Mexico, it has been found that almost 70% of school peers associated overweight or obesity with negative characteristics such as "bad, dumb, loose, clumsy, with lack of discipline" [83]. Tiggerman and Barrett [84] found that children between the ages of 7 and 13 rated overweight children as less attractive (94%), less popular (81%) and lazier (86%) than normal weight children.
Other studies have identified that the subject of Physical Education at the basic and secondary school levels represents an aversive situation for students with excess weight, who expect to be accepted and respected by peers and the group [68,83]. Prejudices and negative attitudes towards excess weight have also been found in teachers, especially in those of physical activity, who have the prejudice that this condition means lower skills and lower performance in students [70,83].
The stigma of overweight or obesity stems from a socio-culturally determined image that is accepted and fulfilled by members of society (that thinness is beauty and means success) and, consequently, individuals suffering from this condition are marked by different prejudices that lack rational foundations [18,23-25,31,54,81,82,84-89]. These beliefs and attitudes are acquired during childhood and, by not being questioned, in adulthood end up becoming prejudices and stereotypes.
The experiences of being mocked, discriminated against and harassed due to body image have consequences for the psychological development of children, since childhood is a period where personality and values are formed that will endure throughout life [82]. Overweight/obese people tend to feel guilty and responsible for their condition, considering that they caused it to themselves, having to fight against habits that prevail in society, such as fast-food consumption and sedentarism, but it is this same society that judges and punishes them [81,86].
In Latin America there are few studies on this subject and it is necessary to develop more research on this condition and its particularities, especially considering that Mexico ranks first in the world in overweight children and young people and that 20 to 25% of the total population of Latin American children and adolescents suffer from overweight and obesity [14]: to this extent, we must respond to this phenomenon.
The included studies were published in health journals (30/31) and not in journals around education, which is indicating that the subject needs to be developed from an educational point of view, since the school environment is a day-to-day environment, in which many children are experiencing social stigma and ridicule from their school peers because of their excess weight.
In Colombia, normative and political foundations have been proposed to address the problem. This can be verified by revising Law 2120 of 2021 [8,90]; but action is missing in schools, as well as the development of scientific evidence of the intervention and prevention of this problem.
Conclusions
First, it is emphasized that the objectives of the study were met and that we were able to compare the hypotheses related in the introduction to the results obtained in the 31 articles included in the present review. The results indicate that overweight or obese children must be supported to fight against different barriers to lose weight, especially psychosocial and socio-cultural barriers, such as social stigma derived from the environment.
Overweight and obese children are more likely to be exposed to social stigma, harassment, intimidation and victimization by their normal weight peers. It was also noted that children are at risk of weight gain due to teasing, harassment and social stigma and their consequences, engaging in a vicious cycle that needs to be broken. Therefore, interventions are needed to address the consequences of bullying and improve the body image of overweight/obese children.
The study shows that it is necessary to propose interventions aimed at children with normal weight to teach them empathic behaviors and altruistic and prosocial conducts towards their overweight peers, in order to reduce, for the latter, a negative psychosocial impact which would lead, inter alia, to lower motivation to exercise, lack of emotional coping to decrease overeating, and even other effects such as poor academic performance, depression, low self-esteem, obesogenic stress, which weighs heavily on overweight or obese children.
Western society presents idealizations of thinness from a very early age that cause prejudice and discrimination towards overweight and obesity, this condition being associated with negative characteristics that do not even have to do with weight, generating a higher level of self-stigma and mental health problems.
The social stigma of overweight and obesity is prevalent and certain age groups and populations, such as school children, may be more vulnerable than others. Therefore, it is important to identify external factors, correlations, categories and moderators of this stigmatization to propose interventions that are effective in reducing the negative impact that this age group suffers.
The multicausal and multidimensional origin of obesity needs an analysis of responsibility from individuals, family and society in general, since apart from the physiological consequences, psychosocial consequences on self-concept, self-esteem, obesogenic stress and body image can lead to more dangerous results than biomedical comorbidities themselves. It is important to improve the well-being and quality of life of these children, who feel socially devalued, through psycho-educational interventions.
Health professionals and primary school teachers should train in non-stigmatizing approaches to overweight and obesity, learning unbiased language and using empathic counseling techniques, such as motivational interviews. In addition, family inclusion and participation should be considered to improve this environment as well.
Healthy lifestyle interventions that promote regular physical exercise, healthy and balanced nutrition and an education in values (altruistic and empathetic prosocial behaviors and positive coping), would help reduce the global indicators of childhood overweight and obesity, combating the psychosocial problems that arise from this condition. The mission of the school should not only be the provision of healthy food but education in healthy lifestyles, installed in early childhood, to be taken to adulthood.
