JOURNAL OF HEALTH, POPULATION, AND NUTRITION 2024; 43:15. [PMID: 38287412 PMCID: PMC10823618 DOI: 10.1186/s41043-024-00512-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/22/2023] [Accepted: 01/25/2024] [Indexed: 01/31/2024]
Abstract
BACKGROUND The misperception of body weight can significantly affect individuals' health behaviors, such as physical activity, diet, and weight management. This study aimed to examine the association between body weight perception and actual body mass index (BMI) among adult women and explore the factors influencing this relationship. METHODS Five hundred forty female individuals aged 18-65 participated in this cross-sectional study. The validated Global Physical Activity Questionnaire was used for data collection. The BMI of the participants was calculated from measured body weight and height. Body weight perception was assessed using a single questionnaire item. The association of BMI and body weight perception was assessed, and the result was categorized as underestimation, consistency, and overestimation. The Chi-square test was used to assess the association between the consistency of BMI and body weight perception by different sociodemographic factors. The kappa test was used to analyze the consistency of BMI and body weight perception. RESULTS Of the 540 participants, 13.3% underestimated their body weight status, 79.1% accurately perceived their body weight status, and 7.6% overestimated their body weight status. Unmarried women (11.7%) were more likely than ever married (4.3%) to overestimate their body weight (p = 0.005). On multiple logistic regression, being unmarried (OR = 1.68 (95%CI 1.01-2.80)) was significantly associated with body weight misperception. Body weight perception and BMI categories showed a significantly good consistency (kappa = 0.612, p < 0.001). Correct perception of body weight was highest among the overweight, followed by normal weight and underweight individuals (82.1%, 75.8%, and 72.2%, respectively). CONCLUSION Body weight perception was well associated with actual body weight status. Unmarried women are more likely to misperceive body weight, particularly overestimating it. Underestimation of body weight was relatively high and much higher than the overestimation, which might keep obese individuals from weight loss activities. Preventing obesity should include awareness about body weight misperceptions.

JAMA Netw Open 2024; 7:e2350940. [PMID: 38198138 PMCID: PMC10782242 DOI: 10.1001/jamanetworkopen.2023.50940] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/30/2023] [Accepted: 11/10/2023] [Indexed: 01/11/2024] Open
Abstract
Importance Use of nonprescribed weight-loss products in adolescents is a public health concern that is associated with negative physical and psychological consequences. However, the prevalence of nonprescribed weight-loss product use in adolescents is unknown. Objective To determine the global prevalence of nonprescription weight-loss product use in children and adolescents. Data Sources Four databases, including MEDLINE, PsycINFO, CINAHL (Cumulative Index of Nursing and Allied Health), and EMBASE, were searched for quantitative studies that reported prevalence data on use of nonprescription weight-loss products with no restrictions on publication date. The search was performed December 1, 2020, and updated March 6, 2023. Study Selection Studies were included in the meta-analysis if they reported the prevalence of weight-loss product use, were published in English, and included individuals 18 years or younger. Data Extraction and Synthesis Data extraction was completed by 2 independent reviewers. Data analysis determined the overall pooled proportion of weight-loss product use in total and during the past week, past 30 days, past year, or lifetime. Inverse variance heterogeneity effect models were used. Main Outcomes and Measures The main outcome measure was the prevalence of nonprescription weight-loss product use in adolescents for all included studies and over the past week, past month, past year, or lifetime. Subgroup analysis included separation of groups by sex, specific weight-loss product types, geographical location, and study publication time. Results A total of 90 articles (604 552 unique participants) were included in the meta-analysis. Of these, 50 studies (56%) were from North America. The reported prevalence of weight-loss product use in adolescents was 5.5% (96% CI, 5.5%-5.6%) overall. When identifying use of weight-loss products in the general population, prevalence was 2.0% (95% CI, 1.9%-2.1%) in the past week, 4.4% (95% CI, 4.3%-4.5%) in the past month, 6.2% (95% CI, 6.1%-6.3%) in the past year, and 8.9% (95% CI, 8.6%-9.2%) in their lifetime. Use of weight-loss products was higher among girls than boys. Conclusions and Relevance This meta-analysis found that use of weight-loss products occurs at high levels in adolescents, especially girls. These findings suggest that, given the ineffectiveness of these products for weight loss coupled with their harmful long-term health consequences, interventions are required to reduce use of weight-loss products in this group.

Relationships of weight perceptions with weight control related behaviors among Chinese children and adolescents: A school-based study in Zhejiang Province. PLoS One 2023; 18:e0285205. [PMID: 37196032 DOI: 10.1371/journal.pone.0285205] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Accepted: 04/17/2023] [Indexed: 05/19/2023] Open
Abstract
OBJECTIVES Weight perceptions have been implicated in weight control related behaviors among children and adolescents, yet studies in mainland China are scarce. We examined the associations of self-perceived weight status and weight misperception with weight control related behaviors in Chinese middle and high school students. METHODS We used cross-sectional data from the 2017 Zhejiang Youth Risk Behavior Survey which that included 17,359 Chinese students, with 8,616 boys and 8,743 girls. Perceived weight status, as well as height, weight and weight control related behaviors information was collected via a self-reported questionnaire. Odds ratios (ORs) with 95% confidence intervals (CIs) calculated by multinomial logistic regression were used to assess the relationships between weight perceptions and weight control related behaviors. RESULTS Among the 17,359 students aged 9 to 18 years, the mean (SD) age was 15.72 (1.64) years. Overall, 34.19% of children and adolescents perceived themselves as overweight and the prevalence of weight misperception was 45.44%, with 35.54% overestimation and 9.90% underestimation. Children and adolescents perceiving themselves as overweight were more likely to have weight control behaviors, with OR was 2.60 (95% CI: 2.39-2.83) for weight control attempt, 2.48 (2.28-2.70) for exercising, 2.85 (2.60-3.11) for dieting, 2.01 (1.51-2.68) for taking laxatives, 2.09 (1.67-2.02) for taking diet pills, and 2.39 (1.94-2.94) for fasting, respectively, compared to those with right weight status. Among children and adolescents with overestimating weight status, the OR was 2.40 (2.22-2.59), 2.50 (2.31-2.70), 2.85 (2.61-3.11), 1.81 (1.39-2.37), 2.20 (1.77-2.74), and 2.16 (1.77-2.63) for weight control attempt, exercising, dieting, taking laxatives, taking diet pills, and fasting, relative to those with accurate weight perception. CONCLUSIONS Self-perceived overweight and weight misperception are prevalent in Chinese children and adolescents, and positively associated with weight control related behaviors.

The Association between Body Weight Misclassification in Adolescence and Body Fat and Waist Circumference in Adulthood: A Longitudinal Study. Nutrients 2022; 14:nu14224765. [PMID: 36432452 PMCID: PMC9693537 DOI: 10.3390/nu14224765] [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: 09/23/2022] [Revised: 10/27/2022] [Accepted: 11/08/2022] [Indexed: 11/16/2022] Open
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.

Abstract
PURPOSE Weight bias internalization (WBI) is associated with disordered eating symptomology and motivation to control weight. The relationship between WBI and specific weight control behaviours and how these behaviours differ between men and women is not well understood. The objectives of this study are to determine (1) the relationship between WBI and weight control behaviours, (2) whether weight perception is independently associated with weight control behaviours, and (3) whether these relationships differ between men and women. METHODS Canadian adults (N = 161; 52.8% women; body mass index [BMI] = 26.5 ± 4.99 kg/m2) completed questionnaires pertaining to WBI, weight control behaviours (healthy, unhealthy, extreme) and weight perception (accurate, under-, or over-estimation compared with objectively measured BMI). The cross-sectional relationship between (1) WBI or (2) weight perception with the total number of healthy and unhealthy or extreme weight control behaviours, and likelihood of performing specific weight control behaviours were assessed with linear, and logistic regression models, respectively. All analyses were conducted adjusting for age, gender, and race. Subsequent analyses were stratified by sex. RESULTS WBI was associated with an increased likelihood of performing exercise for weight loss (OR 2.28, p < 0.05); increased likelihood of skipping meals in women (OR 2.57, p < 0.01), and consuming little amounts of food and food substitutes in men (OR 2.28, p < 0.01 and OR 2.17, p < 0.05, respectively). Weight perception was not associated with weight control behaviours. CONCLUSIONS WBI was associated with various weight control behaviours. This study highlights the importance of assessing WBI in clinical practice with patients seeking to manage their weight. Future longitudinal research should be conducted to further understand the behavioural and health effects from WBI. LEVEL V Cross-sectional descriptive study.

Abstract
Objective: Children and parental awareness regarding weight is linked to the development and management of overweight and obesity. The aim of this study is to assess the actual weight, perceived weight, and desired weight of Romanian school children. Methods: A cross-sectional study was conducted in 2019 in seven schools from two counties of Romania and included 880 pupils aged between 10 and 15 years old and 665 parents. We administrated confidential questionnaires to the participants, and we measured children’s weight and height during school activities. Results: A total of 61.0% of pupils had normal weight, 7.4% were underweight, and 31.6% were overweight or obese. A total of 66.7% of normal weight children, 56.5% of overweight children, and 40% of underweight children perceived their weight accurately. Regarding parents, a majority correctly appreciated the weight of their normal weight children and only a third appreciated correctly the body weight of their underweight and overweight children. Factors such as body mass index, gender, weight related behaviors, parents’ estimation about their children’s weight, discussions of weight topics inside family, and bullying, cyberbullying and exclusion from groups were associated with misperceptions. Conclusion: The study provides useful information for health education activities targeting both children and their parents regarding appropriate body weight management of children.

[PMID: 34774645 DOI: 10.1016/j.jad.2021.11.018] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/17/2020] [Revised: 10/02/2021] [Accepted: 11/07/2021] [Indexed: 12/12/2022]
Abstract
BACKGROUND Suicide has become a severe public health issue worldwide. Body weight has been put forward as a potentially modifiable element for suicide thought and behavior. However, there are discrepancies across previous studies. Furthermore, the relationships of body weight with suicidal ideation and suicide attempt among low- and middle-income countries (LMICs) remain unclear. Therefore, we addressed this issue among 104,907 adolescents of 12-15 years old in 45 LMICs. METHODS The present study used data from the Global School-based Student Health Survey (GSHS). Suicidal ideation and suicide attempt during the last year were self-reported. Participants were classified intro underweight, normal weight, overweight and obesity according to their body mass index classification. Multivariable logistic regression and meta-analyses based on country-wise estimates were conducted. RESULTS The prevalence of suicidal ideation and suicide attempt were 11.8% and 13.0%, respectively. Countrywide meta-analysis demonstrated that overweight and obesity were significantly associated with increased risks of suicidal ideation (For overweight: OR = 1.10; 95% CI = 1.01-1.20; for obesity: OR=1.17; 95%CI: 1.01-1.35) and suicide attempt (For overweight: OR = 1.12; 95% CI = 1.02-1.23; for obesity: OR=1.12; 95%CI: 1.00-1.25). Subgroup analyses showed that the associations between overweight/obesity and suicide attempt were significant for girls but not for boys. LIMITATIONS The cross-sectional design cannot explore causality; mental health factors were not assessed; suicidal behaviors were self-reported; significant heterogeneity across countries; only students attending school were included. CONCLUSIONS Overweight/obesity was significantly associated with the risk of suicidal ideation and suicide attempt among adolescents in LMICs.

Abstract
Electronic cigarette use among American adolescents is a major public health concern given the negative health consequences of nicotine in youth. Recent literature has shown that weight control may be one motivation for use in this population. This study examined associations between intention to lose weight and e-cigarette use among adolescents having overweight or obesity from an ethnically diverse sample of Texas youth by gender. We performed a cross-sectional analysis of a state representative sample of 9056 eighth and eleventh grade students from the 2015-2016 Texas School Physical Activity and Nutrition (Texas SPAN) study. Validated survey items assessed weight intentions and e-cigarette use. Staff collected anthropometric measures. Logistic regression analysis was conducted to assess the relationship between e-cigarette use and weight intentions with gender interaction, adjusting for grade, race/ethnicity, economic status, weight-behaviors and stratified by BMI class. More than half (50.9%) of the weighted sample were Hispanic and 12.5% were Non-Hispanic Black; 8.5% used e-cigarettes; and 50.0% intended to lose weight. Of the 40.2% of the sample having overweight or obesity, 82.9% intended to lose weight. Among respondents with obesity, use of e-cigarettes was significantly higher among males intending to lose weight than among females intending to lose weight (12% versus 6%, p = 0.007). These findings contrast with previous research suggesting that e-cigarette use in females is more likely to be motivated by an intent to lose weight. The ethnic diversity of the Texas SPAN population may explain this discrepancy.

Abstract
Purpose The aims of this study were to evaluate high school pupils’ relationships with their parents, schoolmates, and friends, and the presence of health-related risk behaviors among the family members and friends on the pupils’ smoking and binge drinking status. Materials and Methods The study was a cross-sectional population-based study that involved a questionnaire, and the sample involved 2908 pupils at high schools in Timis county, Romania. In our study, the following factors related to family members and friends and the living environment were identified. First, there were issues with the relationships with parents among some pupils, with 23.2% being neither satisfied nor unsatisfied and 4.9% being unsatisfied. Second, there were also issues regarding some pupils’ satisfaction with the financial situation of their family, with 21.8% being neither satisfied nor unsatisfied and 16.4% being unsatisfied. An odds ratio (OR) is a statistic that quantifies the strength of the association between two events. Results There were 1495 (51.5%) girls and 1407 (48.5%) boys aged 14–20 years, and 79.2% came from organized families. Among the pupils, 71.1% reported that they were satisfied with their relationship with their parents, while 4.9% were unsatisfied. Additionally, 46.2% were satisfied with the financial status of their families, while 16.4% were unsatisfied. Moreover, 59.2% were satisfied with their relationship with their schoolmates and 80.2% were satisfied with their relationship with their friends, while only 1.8% were unsatisfied with their relationship with their friends. The logistic regression model of the pupils’ smoking status identified two moderate predictive factors: this was defined “>1” friends who smoke (odds ratio [OR]=2.875) and smoking status of siblings (OR=2.222). The major predictive factor in the logistic regression model of occasional alcohol consumption in high quantities by pupils was male gender (OR=5.148). Conclusion The predictive model of pupils’ smoking status identified the following moderate predictors: high number of friends who smoke and smoking status of siblings. The major predictor in the model of occasional alcohol consumption in high quantities by pupils was male gender.

Abstract
This study aimed to identify associations among self-perceived weight status, accuracy of weight perceptions, and weight control behaviors, including both healthy and unhealthy behaviors, in a large, nationally representative sample from an East Asian country. Data were collected from the 2016 Korean Study of Women's Health Related Issues, a population-based, nationwide survey. Accurate weight perceptions were investigated by comparing body mass index (BMI) categories, based on self-reported height and weight, and weight perceptions. Weight control behaviors over the previous 12 months were additionally surveyed. Odds ratios (ORs) and 95% confidence intervals (CIs) are presented as an index of associations. Among normal weight, overweight, and obese women, 12.8%, 44.3%, and 17.4% under-assessed their weight; 17.9% of normal weight women over-assessed their weight. Both weight status according to BMI category and weight perceptions were strongly associated with having tried to lose weight. Exercise and diet (ate less) were the most commonly applied weight control behaviors. Misperception of weight was related to more unhealthy weight control behaviors and less healthy behaviors: Women who under-assessed their weight showed a lower tendency to engage in dieting (OR = 0.57, 95% CI = 0.43-0.75) and a greater tendency to fast/skip meals (OR = 1.47, 95% CI = 1.07-1.99). Meanwhile, normal weight or overweight women who over-assessed their weight were more likely to have engaged in fasting/skipping meals or using diet pills (OR = 5.72, 95% CI = 2.45-13.56 for fasting/skipping meal in overweight women; OR = 1.62, 95% CI = 1.15-2.29 and OR = 3.16, 95% CI = 1.15-8.23 for using diet pills in normal and overweight women). Inaccuracy of weight perceptions in any direction (over/under) were related to more unhealthy weight control behaviors and less healthy weight control behaviors, especially in normal and overweight women.

Abstract
INTRODUCTION This study aimed to analyze the association between nutritional status, body image perception, and extreme weight control behaviors among adolescents. METHODS This is an analytical cross-sectional study conducted in Brazil based on the National Adolescent Student Health Survey (Pesquisa Nacional de Saúde do Escolar - PeNSE) of 2015, with adolescents aged 13 to 17 years. Nutritional status and body image perception were the independent variables. The two dependent variables were vomiting or laxative use and use of medicines and other formulas for weight control in the 30 days prior to data collection. We used Poisson regression models for association, with demographic variables for control. RESULTS 7.4% of adolescents (95%CI 6.7 - 8.2) reported vomiting or using laxatives, with no difference between genders. The prevalence of use of medicines and formulas was higher among boys (7.8%; 95%CI 6.6 - 8.9). The association between nutritional status and extreme behaviors was not significant. However, the prevalence of vomiting or laxative use for adolescents who considered themselves very fat was 2.3 (95%CI 1.1 - 4.7) times higher for boys and 5.3 (95%CI 3.3 - 8.6) times higher for girls, while the use of medicines and formulas was 4.0 (95%CI 2.3 - 7.1) times higher for girls who considered themselves very fat. CONCLUSION Body image perception seems to have a greater influence on extreme behaviors than nutritional status. Strategies involving health services and schools have great potential to impact the self-esteem and health of students positively.

The Relationship Between Body Image Concerns and Weight-Related Behaviours of Adolescents and Emerging Adults: A Systematic Review. BEHAVIOUR CHANGE 2018.

Abstract
This systematic review investigates evidence on the association between body image concerns and weight-related behaviours of adolescents and emerging adults. It includes peer-reviewed journal articles reporting research involving body image concerns and weight-related behaviours of adolescents and emerging adults, published between 2005–2017, and located through systematic searches from four databases. This review includes studies from 11 countries or regions: United States (n = 13), Asia (n = 9), Europe (n = 8), Middle East (n = 3), South America (Brazil; n = 3), Canada (n = 3), Australia (n = 1), New Zealand (n = 1), Trinidad (n = 1), Turkey (n = 1) and Seychelles (n = 1); 24 different countries (n = 1); three Asian countries and the United States (n = 1). Out of 46 studies included in this review, 45 studies reported a positive association between body image concerns and weight-related behaviours. Adolescents and emerging adults who misperceived their weight engaged in weight-related behaviours. Higher body dissatisfaction had a significant association in the development of eating disorders and extreme weight-loss behaviours. Body image concerns play a significant role in adolescents and emerging adults engaging in weight-related behaviours. Experimental research designs are required to determine the causality of this association. Evidence strongly suggests policy makers and public health practitioners contemplate strategies to promote positive body image and healthy weight-related behaviours among adolescents and emerging adults.

Abstract
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.

Abstract
OBJECTIVE To investigate the association between the perception of body weight (as above or below the desired) and behaviors for body weight control in adolescents. METHODS This was a cross-sectional study that included 1051 adolescents (aged 15-19 years) who were high school students attending public schools. The authors collected information on the perception of body weight (dependent variable), weight control behaviors (initiative to change the weight, physical exercise, eating less or cutting calories, fasting for 24h, taking medications, vomiting, or taking laxatives), and measured body weight and height to calculate the body mass index and then classify the weight status. Associations were tested by multinomial logistic regression analysis. RESULTS Adolescents of both sexes who perceived their body weight as below the expected weight took more initiatives to gain weight, and those who perceived themselves as overweight made more efforts to lose weight. In adolescents who perceived themselves as overweight, the behavior of not taking medication was associated with the outcome only in boys (Odds Ratio=8.12), whereas in girls, an association was observed with the variables eating less, cutting calories, or avoiding fatty foods aiming to lose or avoid increasing body weight (Odds Ratio=3.39). Adolescents of both sexes who practiced exercises were more likely to perceive themselves as overweight (male Odds Ratio=2.00; Odds Ratio=1.93 female). CONCLUSION The perception of the body weight as above and below one's expected weight was associated with weight control behaviors, which were more likely to result in initiatives to lose and gain weight, respectively.

Abstract
OBJECTIVE Sexual minority girls (lesbian/bisexual) and girls with overweight/obesity experience high rates of discrimination and mental distress. This study explored whether BMI or perceived weight status might compound sexual minority girls' risk for harassment and mental distress. METHODS Data on female students from the national 2015 Youth Risk Behavior Survey (n = 7,006) were analyzed. Logistic regression was used to examine differences in bullying, harassment, and mental distress across sexual identity/BMI groups: heterosexual/normal-weight, heterosexual/overweight, sexual minority/normal-weight, and sexual minority/overweight. Procedures were repeated with four analogous groups created from sexual identity and perceived weight. RESULTS Across sexual identity/BMI groups, being overweight increased heterosexual females' odds of being bullied or experiencing suicidal thoughts and behaviors. Regardless of weight status, sexual minority females had greater odds for each outcome than heterosexual females. Sexual minority females who perceived themselves as overweight had greater odds of suicidality than all other sexual minority/perceived weight groups. CONCLUSIONS Double jeopardy may exist for sexual minority female students who perceive themselves as overweight. Professional development with school staff on how to create a positive climate for sexual minorities and those with overweight/obesity and addressing positive identity and body image within school-based suicide prevention efforts may be important to the well-being of adolescent girls.

Abstract
OBJECTIVE The purpose of this study was to examine the cross-sectional association between weight misperception among young adults with overweight/obesity and disordered eating behaviors. METHOD In a subsample of young adults with overweight or obesity participating in Wave III (2001-2002) of The National Longitudinal Study of Adolescent to Adult Health (n = 5,184), we examined the cross-sectional association between weight under-perception (i.e., perceiving oneself to be at a healthy body weight or underweight) and disordered eating (fasting/meal skipping for weight control, purging/pills for weight control, overeating/loss of control eating, and use of performance-enhancing products/substances). RESULTS About 20% of young adult females under-perceived their weight compared to 48% of males. Individuals who misperceived their weight as healthy were significantly less likely to report fasting/meal skipping (Females: OR: 0.25, 95% CI: 0.14-0.43; Males: OR: 0.31, 95% CI: 0.20-0.48) and vomiting or taking diet pills/laxatives/diuretics (Females: OR: 0.10, 95% CI: 0.04-0.25; Males: OR: 0.10, 95% CI: 0.04-0.25) for weight control. Among females, those who misperceived their weight status as healthy were also less likely to report overeating or loss of control eating (OR: 0.41, 95% CI: 0.24-0.71). Greater use of performance-enhancing products/substances was seen among males who under-perceived their weight as healthy (OR: 2.06, 95% CI: 1.57-2.72) and among both females (OR: 2.29, 95% CI: 1.40-20.0) and males (OR: 2.27, 95% CI: 1.13-4.55) who perceived themselves to be underweight. DISCUSSION Weight under-perception among young adults with overweight/obesity may convey some benefit related to disordered eating behaviors, but could be a risk factor for the use of performance-enhancing products/substances. © 2016 Wiley Periodicals, Inc.

Abstract
Objectives: To investigate the prevalence of inaccurate estimation of own body size among Brazilian schoolchildren of both sexes aged 7-10 years, and to test whether overweight/obesity; excess body fat and central obesity are associated with inaccuracy. Methods: Accuracy of body size estimation was assessed using the Figure Rating Scale for Brazilian Children. Multinomial logistic regression was used to analyze associations. Results: The overall prevalence of inaccurate body size estimation was 76%, with 34% of the children underestimating their body size and 42% overestimating their body size. Obesity measured by body mass index was associated with underestimation of body size in both sexes, while central obesity was only associated with overestimation of body size among girls. Conclusions: The results of this study suggest there is a high prevalence of inaccurate body size estimation and that inaccurate estimation is associated with obesity. Accurate estimation of own body size is important among obese schoolchildren because it may be the first step towards adopting healthy lifestyle behaviors.

The Effects of Weight Perception on Adolescents' Weight-Loss Intentions and Behaviors: Evidence from the Youth Risk Behavior Surveillance Survey. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2015; 12:14640-68.

Abstract
The objective of this study was to examine the correlation between self-perception of being overweight and weight loss intentions, eating and exercise behaviors, as well as extreme weight-loss strategies for U.S. adolescents. This study uses 50,241 observations from the Youth Risk Behavior Surveillance Survey (YRBSS) 2001–2009, which were nationally representative sample of 9th- through 12th-grade students in both public and private schools in the US. This study finds that, irrespective of the weight status base on self-reported weight and height, adolescents who perceive themselves as overweight have a stronger intention to lose weight, but do not develop better eating and exercise habits, compared with their counterparts of same gender and reported weight status. Normal-weight adolescents, if they perceive themselves as overweight, are more likely to engage in health-compromising weight-loss methods. This study shows that it is critical to transform weight-loss intentions into actual behaviors among overweight/obese adolescents and improve the efficacy of behavioral interventions against childhood obesity. It also highlights the need of establishing a correct perception of body weight among normal weight adolescents to curb extreme weight-loss methods.

Abstract
Background Obesity is now common and this may have altered visual perceptions of what constitutes a ‘normal’ and therefore healthy weight. The present study examined cross-cultural differences in male and female participants’ ability to visually identify the weight status of photographed Caucasian males. Methods Five hundred and fifty three male and female young adults from the US (high obesity prevalence), UK and Sweden (lower obesity prevalence) participated in an online study. Participants judged the weight status of a series of photographed healthy weight, overweight and obese (class I) Caucasian males and rated the extent to which they believed each male should consider losing weight. Results There was a strong tendency for both male and female participants to underestimate the weight status of the photographed overweight and obese males. Photographed males were frequently perceived as being of healthier weight than they actually were. Some modest cross-cultural differences were also observed; US participants were worse at recognising obesity than UK participants (p < 0.05) and were also significantly more likely to believe that the photographed obese males did not need to consider losing weight, in comparison to both the UK and Swedish participants (ps < 0.05). No cross-cultural differences were observed for perceptions or attitudes towards the photographed healthy weight or overweight males. Conclusions The weight status of overweight and obese (class I) Caucasian males is underestimated when judged by males and females using visual information alone. This study provides initial evidence of modest cross-cultural differences in attitudes toward, and the ability to recognise, obesity in Caucasian males.

Abstract
BACKGROUND Mothers often do not realize when their child is overweight. We aimed to compare mothers' perceptions of children's weight before and during puberty, and to explore factors at 7 years predicting recognition of overweight at 16 years. METHODS Mothers of 237 children (136 boys) from the EarlyBird study estimated their own weight category and that of their child aged 7 years and 16 years. The children estimated their own weight category at 16 years. Annual measures: body mass index standard deviation score (BMIsds), per cent fat, physical activity. Pubertal development assessed by age at peak height velocity (APHV). MATERNAL MEASURES: BMI, education, socio-economic status. RESULTS At 7 years 21% of girls and 16% of boys were overweight or obese, rising to 27% and 22% respectively at 16 years. The accuracy of the mother's perception of her child's weight category improved from 44% at 7 years to 74% at 16 years, but they were less able to judge overweight in sons than daughters. The mothers' level of concern about overweight was greater for girls than boys, and increased for girls (52% mothers of overweight/obese girls were worried at 7 years, 62% at 16 years), but remained static in the boys (42% vs. 39%). Over 80% of the youngsters realized when they were overweight, but 25% normal-weight girls also classed themselves as overweight. Only BMI predicted a mother's ability to correctly perceive her child's weight. Neither her awareness, nor concern, about the child's weight at 7 years had any impact on the trajectory of the child's BMI from 7 years to 16 years. CONCLUSIONS Parents are central to any successful weight reduction programme in their children, but will not engage while they remain ignorant of the problem. Crucially, any concern mothers may have about their child's excess weight at 7 years appears to have no impact on subsequent weight change.

Abstract
OBJECTIVES To evaluate dose-response associations between misperceived weight and 32 health risk behaviors in a nationally representative sample of US adolescents. METHODS Participants included 13,864 US high school students in the 2011 Youth Risk Behavior Survey. Comparing the degree of agreement between perceived and reported actual weight, weight misperception was determined as 5 categories. Multivariable-adjusted logistic regression analyses evaluated associations of weight misperception with 32 health risk behaviors. RESULTS Both underestimated and overestimated weight were statistically significantly associated with all 32 health risk behaviors in a dose-response manner after adjustment for age, sex and race/ethnicity, where greater weight misperception was associated with higher engagement in health risk behaviors. CONCLUSIONS Understanding potential impacts of weight misperception on health risk behaviors could improve interventions that encourage healthy weight perception and attainment for adolescents.

Abstract
This study investigated the relationship between adolescents' body weight misperception and the Human Development Index (HDI) of the cities in which they live in Brazil. Data from a large national survey that included 60,973 boys and girls between 13 and 15 yr. (M = 14.2, SD = 1.1; 47.5% boys, 52.5% girls) were analyzed. Regression analyses were adjusted for potential confounding factors such as population density, income inequality, nutritional status (BMI), and mothers' education. In both sexes, the relationship between perceived underweight showed an inverse relationship with HDI. The highest prevalences of participants who perceived themselves as overweight for girls were found in cities with high HDI.
