Motivos e prevalência de insatisfação com a imagem corporal em adolescentes

Examining body appreciation in six countries: The impact of age and sociocultural pressure

Previous research on body appreciation across the lifespan has produced conflicting results that it increases with age, decreases with age, or is generally stable with an increase in women over 50-years-old. Furthermore, most of the research has been conducted in White, Western populations. Cross-cultural research suggests that both Chinese and African women experience similar sociocultural pressures as White Western women, and that appearance ideals are shifting to resemble a more Western ideal. We cross-sectionally and cross-culturally examined body appreciation across the lifespan, recruiting White Western women (UK, USA, Canada, and Australia), Black Nigerian women, and Chinese women. 1186 women aged 18-80 completed measures of body appreciation, internalisation of thin and athletic ideals, and perceived sociocultural pressure. Body appreciation did not vary with age in women from any country. Nigerian women reported the highest body appreciation, and Western women the lowest. Higher thin/athletic ideal internalisation, and higher perceived sociocultural pressure were significantly associated with lower body appreciation in all countries and age-groups. Overall, our findings indicate that although levels of body appreciation differ drastically between ethnicities and cultures, it is generally stable across age, and shows cross-culturally robust relationships between sociocultural internalisation and pressure.

Urbanisation negatively impacts sleep health and mood in adolescents: a comparative study of female students from city and rural schools of North India

This study investigated the impact of social settings on sleep, physical and mental health in female adolescents of North India (latitude 29.5 oN; longitude 77.5 oE). Using a battery of questionnaires, we compared the chronotype, sleep-wake pattern, sleep health (e.g. sleep quality, daytime sleepiness and fatigue) and mood (via depression, anxiety and stress symptoms) in female students (age 14-18 years) from rural (N = 719) and urban (N = 1033) schools separated by about 35 km, but families had almost similar socio-demographic details. The morning type was prevalent amongst rural, whilst the evening type was prevalent amongst urban students who also had access to smart phones, suggesting a possible greater use of the internet. There were greater negative sleep effects, daytime sleepiness, overall poor sleep quality, higher fatigue and anxiety levels in urban than the rural cohort. Interestingly, these measures also differed between school days and free days, suggesting an impact of the conflict between internal biological and social timings (= social jet lag). We also found a significant relationship between chronotype, internet addiction, mood-related parameters and measures of sleep health. Overall, these results suggest a possible impact of social settings on sleep health and mood-related behaviours in female adolescents.

Is There an Association between Food Consumption According to the Degree of Processing and Body Image (Dis)satisfaction in Adolescents?

(1) Background: Adolescence is characterized by changes in eating habits, with increased consumption of ultra-processed foods and reduced intake of unprocessed or minimally processed foods, which can affect body image satisfaction. Thus, this study aims to verify the association of food consumption according to the degree of processing with body image (dis)satisfaction in adolescents from the 1997/1998 birth cohort of São Luís, Maranhão. (2) Methods: A cross-sectional study was conducted with 2515 adolescents aged between 18 and 19. Food consumption was stratified based on the NOVA classification in culinary preparations, processed foods, and ultra-processed foods, categorized into tertiles. Body image (dis)satisfaction was evaluated based on the Stunkard Body Scale and was classified as satisfaction, dissatisfaction with thinness, and dissatisfaction with excess weight. Multinomial logistic regression was used for associations. (3) Results: Among the adolescents, 77% considered themselves dissatisfied with their body image, with 42.8% dissatisfied with being thin and 34.2% dissatisfied with excess weight. However, food consumption, according to the degree of processing, was not associated with body image (dis)satisfaction. (4) Conclusion: This work highlighted the prevalence of body image dissatisfaction among adolescents but found no association between body (dis)satisfaction and food consumption according to the degree of processing.

Secular trends in body image dissatisfaction and associated factors among adolescents (2007-2017/2018)

OBJECTIVE

To assess secular trends in body image dissatisfaction and associated factors among adolescents over a 10-year period (2007-2017/2018).

METHODS

The sample included 1,479 (2007, n = 531; 2017/2018, n = 948) high school adolescents of both sexes, aged 14 to 18 years, of schools in a city in southern Brazil, in 2007 and 2017/2018. Data were collected on sex, age, physical activity (IPAQ, short form), anthropometric measurements (body weight, height, and triceps and subscapular skinfolds), and body image dissatisfaction (figure rating scale). The variables were compared with Independent samples t-test and Mann-Whitney U-test. The associations between sex and other variables were examined with chi-square test, and the factors associated with body image were identified with multinomial logistic regression.

RESULTS

Most adolescents were dissatisfied with their body image in 2007 (65,2%) and 2017/2018 (71,1%). The prevalence of body dissatisfaction increased by 9.2% over the 10-year period, particularly dissatisfaction with thinness (21.3%). After stratification by sex, in 2017/2018 sample, dissatisfaction with overweight was 46.1% greater in boys, and dissatisfaction with thinness was 66.9% greater in girls. Factors found to be significantly associated with body image dissatisfaction were physical activity level, and body adiposity.

CONCLUSIONS

There was a secular trend toward increased body image dissatisfaction in both sexes. Future efforts should go beyond scientific production, in public and private environments aimed at increasing awareness of health issues related to body care in the physical, psychological, and environmental domains.

Body dissatisfaction, drug use, and associated factors among adolescents in three Brazilian cities

OBJECTIVE

analyze the association between drug use and body dissatisfaction among adolescents in three Brazilian cities.

METHOD

cross-sectional study, using a nested randomized controlled trial to evaluate the drug use prevention program #TamoJunto2.0 of the Ministry of Health in Brazilian schools. The sample consisted of 5,213 students from 73 schools in three Brazilian cities. The outcome body satisfaction was analyzed using the Stunkard scale and the explanatory variables were drug use and sociodemographic data.

RESULTS

the adolescents were between 12 and 14 years old; about 69.9% of them reported body dissatisfaction, and 35.67% used alcohol in the previous year. Dissatisfaction due to overweight was higher among girls (41.5%) and dissatisfaction due to underweight was higher among boys (33.1%). Adolescents who used marijuana were 39% (OR=1.39) more likely to feel dissatisfied due to underweight and being a girl increased the chances of feeling dissatisfied due to overweight by 24% (OR=1.24).

CONCLUSION

the levels of body dissatisfaction deserve attention in hebiatric nursing care and reinforce the importance of educational strategies addressing body image and drug use, relating them to the various subjective attributes that can affect the health of adolescents, whether in the community or at school.

(1) High prevalence of body dissatisfaction related to overweight. (2) Girls presented 24% more chances of feeling body dissatisfaction due to overweight. (3) Marijuana use in adolescence can increase by 39% body dissatisfaction due to underweight. (4) Last year, about 35.7% of adolescents had already consumed alcohol. (5) Health promotion and stimulation of positive perceptions of self-image.

Negative Physical Self-Concept Is Associated to Low Cardiorespiratory Fitness, Negative Lifestyle and Poor Mental Health in Chilean Schoolchildren

Background: Evidence suggests that physical self-concept (PSC) is linked to well-being in children and adolescents. Objective: The objective was to investigate the association of PSC with mental health (i.e., depression and body image), physical status (i.e., fitness and weight status) and lifestyle (physical activity (PA) patterns and nutritional level) in Chilean schoolchildren. Methods: A total of 617 schoolchildren (n = 271 girls and n = 346 boys) aged 10−14 years participated in this study. Self-concept, depression and body image dissatisfaction were determined by questionnaires. Physical fitness, PA, screen time (ST), Mediterranean diet (MD) adherence and anthropometric parameters were also included. Results: Poor PSC was linked to bad cardiorespiratory fitness (CRF) (<42 VO2max) (OR 1.64; 95%CI 1.12−2.34; p = 0.01), severe body image dissatisfaction (OR 2.51, 95%CI 0.99−6.35; p = 0.05), ST of more than two hours a day (OR 2.1; 95%CI 1.41−3.12; p < 0.001), PA after school of no more than two hours per week (OR 1.52; 95%CI 1.08−2.13; p = 0.015) and depression (OR 1.80; 95%CI 1.1−2.92; p = 0.017). High nutritional level showed an association with general PSC and general self-concept (p < 0.05). Absence of body image dissatisfaction was related to general self-concept (p < 0.01) and physical condition dimensions (p < 0.05). Conclusions: PSC is associated with CRF, PA after school, ST and nutritional level. According to mental health variables, poor PSC is related to depression in Chilean schoolchildren. Therefore, promoting a healthy lifestyle among children should be a target of community- and school-based interventions to promote PSC.

Body image and association with BMI, and purgative behaviours for weight control in adolescents aged 11-14 years

We aimed to evaluate the association of overweight/obesity based in BMI and purgative behaviours with body image (BI). Methods: Cross-sectional study, with probabilistic sample of 976 adolescents, aged 11-14 years, from the city of Florianópolis, Brazil. Multivariate analyses were performed. Overweight (including obesity) and four variables related to purgative methods for body weight control or eating behaviour were evaluated as outcomes, while BI satisfaction was the primary independent variable in each model. Models were controlled for age, sex, type of school (public or private), intake of fruit and vegetables, number of daily meals, and physical activity scores levels. A total of 31·4 % of adolescents wanted to enlarge their silhouette and 45·6 % wanted to reduce it. Among overweight/obese adolescents, 9·6 % were satisfied with their bodies, while 89·8 % wanted to reduce it, while among the not overweight/obese adolescents, 45·4 % wanted to enlarge their silhouette (P < 0·001). Multivariate analysis showed that the odds for overweight/obesity is higher among adolescents who wanted to reduce their silhouette (OR = 11·20; 95 % CI = 5·55, 22·58). Adolescents who want to reduce their silhouette are more likely to use diuretics (OR = 3·08; CI = 1·78, 5·32) and to use laxatives (OR = 2·10; CI = 1·20, 3·68). A significant association was also found between dissatisfaction with BI and overeating (among those who want to enlarge their silhouette: OR = 1·78; CI = 1·12, 2·85 and among those who want to reduce their silhouette: OR = 1·81; CI = 1·03, 3·19). Conclusion: BI dissatisfaction was associated with overweight/obesity, as well with overeating, and the use of purgative methods.

Systematic Review of Digital Interventions for Adolescent and Young Adult Women's Body Image

Background

A growing number of digital interventions have been developed to address a range of mental health issues including body image. Identifying effective interventions for body image is important given the prevalence of body image concerns and their associated negative outcomes among young women. This review aimed to critically evaluate current evidence on the use of digital interventions for adolescent and young adult women's body image.

Methods

A literature search was performed in November 2021 across three databases, PsychINFO, Web of Science and Pubmed to identify studies published with keywords and synonyms of "body image" and "digital interventions" that have been conducted with girls/women aged 10-25 years. Studies were included if they assessed a universal body image intervention delivered through a digital platform (e.g., web-based, mobile phone) and if they reported body image outcomes using validated measures. Two authors independently screened studies extracted data and assessed the quality of studies.

Results

Eight of 15 interventions were effective in improving at least one body image outcome from pre-post intervention; however, effect sizes were mostly small-medium, and few effects were maintained at follow-up. Studies were heterogeneous in terms of delivery format, duration, sample characteristics, quality, and outcomes.

Discussion

Findings suggest that digitally delivered interventions can effectively improve some body image outcomes in young women. Characteristics of effective studies are discussed and suggestions for future work on intervention development in this field are provided.

Body image in children and adolescents diagnosed with the human immunodeficiency virus: a systematic review

CONTEXT

The relationship with body image, which is the way the body presents itself to each subject, can be aggravated in children and adolescents diagnosed with an human immunodeficiency virus (HIV) infection, since these patients use antiretroviral therapy and may suffer from the adverse effects of the treatment due to continuous use of medication.

OBJECTIVE

To estimate the prevalence of body image dissatisfaction, to describe the assessment methods, and to identify associated factors in children and adolescents diagnosed with HIV.

DESIGN AND SETTING

This is a systematic review. Department of Physical Education, Florianópolis - Brazil.

METHODS

We followed the procedures of the Preferred Reporting Items for Systematic Reviews (PRISMA) and the Cochrane recommendations in the selection of articles through a search performed in eight databases.

RESULTS

Prevalence of body image dissatisfaction due to thinness was between 36.7-52.0% in males and 28.1-36.4% in females, and body image dissatisfaction due to overweight was between 8.0-31.2% in males and 21.9-50.0% in females. Factors associated with body image dissatisfaction were as follows: female sex, older age, low levels of physical activity, low self-esteem, higher body fat, higher body weight, greater arm muscle area, triceps skinfold thickness, and higher body mass index.

CONCLUSION

Children and adolescents of both sexes diagnosed with HIV infection are dissatisfied by thinness and overweight of their body image.

Parental practices, body dissatisfaction and weight control practices in female adolescents from public schools in southern Brazil

The objective was to verify the association between body dissatisfaction (BD) - constituted by the desire to lose weight - with family and personal aspects related to the shape of the body and weight control practices in female adolescents. A cross-sectional, observational epidemiological study with adolescents aged 12-19 years, enrolled in classes of the 8th and 9th years of public schools belonging to the urban area of the city of Caxias do Sul/Rio Grande do Sul, Brazil, was conducted. A self-applicable questionnaire was used. BD was assessed using a silhouette scale. Multivariate regression was performed using Poisson regression with robust variation, hierarchically using a pre-established conceptual model, using the prevalence ratio (PR) adjusted with 95 % CI as a measure of effect. A significance level of 5 % (P ≤ 0·05) was considered. Among the 685 female students, 77·2 % had BD. The father's incentive to diet sometimes (PR 1·19; 95 % CI 1·07, 1·32; P ≤ 0·001) and always (PR 1·15; 95 % CI 1·03, 1·28; P ≤ 0·001), trying to lose weight (PR 1·63; 95 % CI 1·33, 1·99; P ≤ 0·001), dieting five times or more (PR 1·22; 95 % CI 1·09, 1·36; P ≤ 0·001) and skipping meals less than once a week (PR 1·16; 95 % CI 1·04, 1·29; P = 0·026) increased the chances of having BD. In conclusion, among the investigated parents' behaviours, only the father's incentive to go on a diet was associated with BD. Adolescent weight control practices increased the chances of having BD. Thus, it facilitates the identification of this condition at an early stage, enabling adequate treatment and prevention of health complications.

Weight stigma and disordered eating behaviors in Pakistani overweight adolescents: the mediating role of body esteem

PURPOSE

Weight stigma has been described as social devaluation of people on the basis of their weight and it is associated with negative consequences. The present study was designed to investigate weight stigma and its relationship with disordered eating behaviors in overweight adolescents. One of the main objectives of this study is to investigate the mediating role of body esteem between weight stigma and disordered eating behaviors in overweight adolescent girls.

METHODS

Through cross-sectional research design and purposive sampling technique, a sample of 200 overweight adolescent girls was recruited from Lahore, Pakistan. Participants were asked to fill self-report measures related to weight stigma, body esteem, and disordered eating behaviors.

RESULTS

SPSS and AMOS were used to analyze the data. Pearson product moment correlation showed that experiences of weight stigma were negatively related to body esteem and positively related to disordered eating behaviors in overweight adolescent girls. Furthermore, structural equation modeling (SEM) showed that body esteem was significantly mediating the relationship between weight stigma and disordered eating behaviors in adolescent girls.

CONCLUSION

It is concluded that weight stigma and body esteem play a significant role in the development and maintenance of disordered eating behaviors in overweight adolescents. Awareness/educational programs could be designed to empower adolescent girls in combating negative consequences of weight stigma. Furthermore, specific programs could be designed at college or university level to boost one's body esteem and reduce disordered eating behaviors.

Body image perception and body composition in early adolescents: a longitudinal study of an Italian cohort

BACKGROUND

Adolescence is a sensitive period of life in which everyone faces physical and psychological changes. No longitudinal studies considering changes in body image perception and body composition in Italian adolescents have been carried out. The aims of this study were to evaluate the longitudinal change in body composition and weight status in a sample of Italian students of both sexes over the 3 years of middle school and to analyse the influence of these parameters on the perception and satisfaction of one's own body image.

METHODS

Sixty-four males and seventy females were followed longitudinally from 11 to 14. Age at first measurement was 11.8 ± 0.3 yrs. in males and 11.9 ± 0.3 yrs. in females, then the students were measured again after 1 year and 2 years. Anthropometric measurements were collected and body composition was assessed by skinfolds. Maturity status was detected by age at menarche in females and by estimated age at peak height velocity in males; sports practice was assessed by a questionnaire. Body Silhouette Charts were used to assess body image perception. The degree of body image dissatisfaction and improper perception of weight status were evaluated. Univariate and multivariate analyses were applied.

RESULTS

Height, sitting height, leg length, and weight increments were higher in males than in females, and in both sexes the sitting height increment was higher than that of leg length. Skinfold thicknesses and percentage of body fat, showed a decrease in males and an increase in females over the 3 years. About 90% of the sample practiced sport during the 3 years. No significant variations in body image perception were observed among repeated measures but significantly differences were observed between sexes. Although the girls showed a lower incidence of overweight and obesity than boys, girls had a higher dissatisfaction than males. Males were less accurate in one's perception of one's own weight status.

CONCLUSIONS

The changes in body composition observed in the sample of the present study were in accordance with their maturity stage. An increase in parameters connected with adiposity is observed in females and a decrease in males. Body image perception did not seem to change with growth, but associations were found between body image perception and BMI and sex. Monitoring body image perception in young adolescents, especially in females and in overweight/obese subjects, is a priority to prevent nutritional disorders.

Body image dissatisfaction and associated factors in adolescents

This study aimed to examine the factors associated with body dissatisfaction in adolescents. This is a cross-sectional study with students from two public and four private schools in the metropolitan region of Rio de Janeiro. Body dissatisfaction was evaluated using the Body Silhouette Scale, by the difference between the image they perceive as their current image and the one they would like to have. The association was assessed by hierarchical logistic regression multinomial model, by estimating odds ratios (OR) and 95% confidence intervals (95%CI). Among the 1,019 adolescents evaluated (13-19 years), 75% showed body dissatisfaction, 41.4% wishing for a smaller silhouette and 33.7% wishing for larger silhouettes. The wish for a smaller silhouette was more significant in girls, overweight adolescents, those with an unsatisfactory meal pattern, and with higher waist circumference. Adolescents that had been exposed to teasing due to their body shape increased the probability of wishing for both smaller and larger silhouettes. Strategies are required for a more positive perception of body image, especially for girls and for overweight adolescents, which provide guidance on adequate meal consumption and prevent exposure to peer teasing, valuing coexistence and well-being in the face of existing bodily differences.

Sports Participation from Childhood to Adolescence is Associated with Lower Body Dissatisfaction in Boys-A Sex-Specific Analysis

OBJECTIVES

This study aimed to analyze the association between body dissatisfaction and sports participation from childhood to adolescence in a school-based sample of adolescents, according to sex.

METHODS

A total of 1011 adolescents of 13.1 ± 2.3 years of age were evaluated. Body dissatisfaction was assessed by the Silhouettes Scale and sports participation for at least one consecutive year was retrospectively assessed by closed specific questions related to childhood and adolescence periods. Body mass index (BMI) and abdominal obesity were objectively measured. Habitual practice of physical activity (PA), socioeconomic status (SES), and ethnicity were assessed through questionnaires.

RESULTS

Sports participation from childhood to adolescence was observed in 55.1% of boys and in 41.2% of girls. Boys with body dissatisfaction showed lower habitual PA in leisure time (Baecke score = 4.38 ± 2.27 vs. 5.15 ± 2.25, p < 0.05) and in total (Baecke score = 9.34 ± 2.64 vs. 9.96 ± 2.68, p < 0.05) than those who were satisfied. No differences were observed among girls. Sports participation from childhood to adolescence was associated with 42% less chance of having body dissatisfaction in boys (OR = 0.58 [95%CI = 0.36-0.94]). No significant association was observed among girls.

CONCLUSIONS FOR PRACTICE

Sports participation from childhood to adolescence was negatively associated with body dissatisfaction in boys. The continuity of physical activity during youth may be an important modifiable factor to reduce body dissatisfaction.

Body dissatisfaction and its association with domains of physical activity and of sedentary behavior in a sample of 15,632 adolescents

Objectives Body image is widely related to behavioral factors in adolescents and negative levels has been associated to poor physical and mental health. This study analyzed the association of physical activity and sedentary behavior with body dissatisfaction in adolescents. Methods Data from 15,632 adolescents between 11 and 17 years from the Brazilian National Scholar Health Survey - PeNSE 2015 were analyzed. Body dissatisfaction was self-reported. Sedentary behavior was assessed by hours in television (TV) viewing and in overall sitting behaviors. Physical activity was assessed by amount of time in domains of active commuting, physical education classes at school, and physical activities outside the school. Analyses were adjusted by age, ethnicity, body mass index, and scholarity of mother. Results Body dissatisfaction prevalence was 18.5%, being higher in girls than boys (24.2 vs. 12.7%, p < 0.001). Female gender (OR = 2.35), higher age-group (OR = 1.64), high scholarity of mother (OR = 1.43), and had overweight/obesity (OR = 2.38/4.81) were positively related to body dissatisfaction. Higher sedentary time was associated with body dissatisfaction in adolescents when compared to less than 2 h/day of sedentary time (OR varying from 1.45 to 2.14). Physical activity was negatively associated with adolescent body dissatisfaction in all assessed domains, with odds ratio varying from 0.66 to 0.89. Conclusions Body dissatisfaction showed an independent association of with total sedentary behavior (positively) and with different domains of physical activity (negatively) in a large scholar sample of Brazilian adolescents.

Perception of body image and nutritional status in adolescents of public schools

OBJECTIVE

To assess body image dissatisfaction among adolescents from Northern Minas Gerais.

METHOD

This is a cross-sectional study with adolescents of both sexes, enrolled in the sixth to ninth year in the municipal public education network. A questionnaire was used, composed of sociodemographic and body image variables, which was obtained through a scale of silhouette figures. The anthropometric measurements of weight and height were performed to estimate body mass index. The correlation between the classification of the body mass index and the body image of adolescents was estimated through weighted Kappa.

RESULTS

A total of 535 adolescents participated, and 24.5% had different classifications between the real and ideal body image. The Kappa index for the classification of body image was 0.51, 0.58 and 0.32 for the total of adolescents, girls and boys, respectively.

CONCLUSION

Public school adolescents are dissatisfied with their self-body image.

Unhealthy weight control behaviors, disordered eating, and body image dissatisfaction in adolescents from São Paulo, Brazil

OBJECTIVE

To identify the frequency of disordered eating (DE) and unhealthy weight control behaviors (UWCB) among adolescents and associations with age, sex, actual weight status, perceived weight status, and body image dissatisfaction.

METHODS

Cross-sectional study of 1,156 adolescents. DE was assessed using a specific self-report questionnaire, UWCB by specific behaviors that were not typically recommended for weight management, and body dissatisfaction by Stunkard's silhouettes.

RESULTS

The frequency of DE was 17.3%, and that of UWCB, 31.9%; 80.1% of participants were dissatisfied with body image. Perception of oneself as overweight was associated with 1.795-fold odds of DE. Those with UWCB had 7.389-fold odds of DE, while DE increased the odds of UWCB 7.280-fold. Girls, participants who perceived themselves as overweight, and those who reported body dissatisfaction were 2.266, 2.381, and 1.752 times more likely to have UWCB, respectively.

CONCLUSION

A high prevalence of UWCB and a moderate prevalence of DE behaviors was found in adolescents from the city of São Paulo, Brazil. Those who perceived themselves as overweight had more DE and UWCB, and both behaviors were related. UWCB was more common in girls and among those dissatisfied with their bodies.

[Excessive alcohol intake and dissatisfaction with body image among adolescents and young adults in a municipality in Bahia State, Brazil]

The study aimed to analyze the association between excessive alcohol intake and dissatisfaction with one's body image in a population of adolescents and young adults. This was a cross-sectional study with a household survey design in a sample of 1,582 individuals 15 to 24 years of age living in Camaçari, Bahia State, Brazil. Excessive alcohol intake was identified by the Alcohol Use Disorder Identification Test (AUDIT), and dissatisfaction with body image was measure with the Silhouette Figure Scale. Confounding variables were: sex, age, race, schooling, work, religion, family composition, number of close friends, marital status, and children. The association between excessive alcohol intake and body dissatisfaction was estimated by logistic regression. Prevalence of excessive alcohol intake was 21.9% (higher in males), and prevalence of body image dissatisfaction was 79.5% (higher in females). No statistically significant association was found between excessive alcohol intake and dissatisfaction with body image. After adjustment of the final model, the variables that remained associated with excessive alcohol intake were religion (OR = 2.02), schooling (OR = 1.63), family composition (OR = 1.61), age (OR = 0.55), and work (OR = 0.61). Although the analyses did not show an association between excessive alcohol intake and dissatisfaction with body image, the study's results call attention to the high prevalence rates for the two phenomena. This shows the need to develop interventions focused on practices of care for this specific population.

The Relative Associations of Body Image Dissatisfaction among Psychiatric Out-Patients in Singapore

Background: Adults with body image dissatisfaction (BID) are more likely to be depressed, anxious, and suicidal when compared to those without intense dissatisfaction over their appearance. The current study aimed to estimate the prevalence and factors associated with BID among out-patients with mental illness in Singapore. Methods: Data was collected from 310 psychiatric out-patients using a self-administered questionnaire. Measurements used were socio-demographic characteristics, Body Mass Index scores, Body Shape Questionnaire, Binge Eating Scale, Eating Attitudes Test, Beck’s Depression Inventory, Beck’s Anxiety Inventory and Alcohol Use Disorders Identification Test. Results: A prevalence of 30.9% of BID was established among psychiatric out-patients in Singapore. Being female, having higher BMI scores, binge eating behavior, eating disorders, and those diagnosed with depression were positively associated with BID. Conclusion: BID is prevalent among those with psychiatric illnesses which could lead to a higher degree of psychological distress and the emergence of eating disorders.

Perfil nutricional e percepção da imagem corporal em adolescentes de escolas públicas e privadas de município mineiro

Introdução: A caracterização do perfil nutricional da população de adolescentes, assim como o diagnóstico de sobrepeso e obesidade, é de suma importância para auxiliar a elaboração de medidas de controle e reversão do quadro, possibilitando melhora na qualidade de vida e a prevenção das doenças crônicas não transmissíveis (DCNTs). Objetivo: Traçar o perfil nutricional e fatores associados (gênero, tipo de escola, idade e percepção da imagem corporal) em adolescentes de município de Minas Gerais. Material e Métodos: Estudo transversal, desenvolvido com estudantes de ambos os gêneros do ensino fundamental 2, com idade entre dez a dezesseis anos, matriculados em escolas públicas e privadas. Foram coletados dados antropométricos de 576 indivíduos, incluindo peso, altura e circunferência da cintura, padronizados de acordo com as orientações do Ministério da Saúde. Também foram coletados dados referentes ao hábito alimentar e a percepção da imagem corporal dos indivíduos, através de questionários semi-estruturados e auto preenchidos. Resultados: Dos adolescentes estudados, 58,7% pertenciam à rede pública de ensino, 64,9% do gênero feminino e a mediana de idade foi de 13 anos. Em relação ao estado nutricional, 1,5% da amostra encontrava-se com a estatura inadequada para a idade, 30,93% apresentavam excesso de gordura abdominal e 34,4% excesso de peso. Em relação a imagem corporal, observou-se que os indivíduos obesos e com sobrepeso apresentaram maior insatisfação com sua imagem corporal, quando comparados ao grupo dos indivíduos eutróficos. Em relação aos hábitos alimentares, 37,1% dos adolescentes relataram nunca realizar o café da manhã, mas em relação as outras refeições (almoço e janta) a maioria relatou consumir sempre. Em relação aos alimentos ultraprocessados, 41,2% dos adolescentes relataram consumir guloseimas diariamente e 33,2%, refrigerantes ou suco em pó. Conclusão: São necessárias medidas que promovam a alimentação saudável, visando a prevenção da obesidade, sobrepeso e das doenças crônicas não transmissíveis em adolescentes.

What are the correlates of body image distortion and dissatisfaction among school-adolescents?

BACKGROUND

Body image is considered as central to many aspects of human functioning including emotions, thoughts, behaviors and relationships. Our study aimed to investigate the prevalence of body image distortion and dissatisfaction among adolescents and to assess their main determinants.

METHODS

This was a cross-sectional school-based study conducted among school-adolescents in the south of Tunisia, between October 2017 and February 2018.

RESULTS

Among 1210 school-adolescents, body image distortion and dissatisfaction prevalence were 44.8% and 42.4%, respectively. Multivariate analysis showed that being in the 16-18 years age group [adjusted odds ratio (AOR) = 1.28, p = 0.046], low family financial situation (AOR = 1.88, p = 0.014), as well as high frequency of eating pasta (AOR = 1.3, p = 0.04) and fast-food consumption (AOR = 1.7, p = 0.042) were independently associated with under-estimated body image. Skipping breakfast (AOR = 1.9, p = 0.017) and having one obese parent (AOR = 1.9, p = 0.01) were independently associated with higher frequency of over-estimated body image. Regarding body image dissatisfaction, independent factors associated with desire to lose weight were: female gender (AOR = 1.53, p = 0.007), high income family financial situation (AOR = 2.1, p = 0.008) and having one parent who is obese (AOR = 2.21, p < 0.001). However, frequent fast-food consumption (AOR = 1.9, p = 0.038) and eating between meals (AOR = 1.57, p = 0.01) were independently associated with a higher desire to gain weight.

CONCLUSIONS

Our study highlighted that the prevalence of body image distortion and dissatisfaction were substantially high among adolescents. Their determinants included socio-demographic factors and lifestyle behaviors. Increased awareness among parents, educators and public health planners may help adolescents improve accuracy of body image attitudes.

Body image satisfaction and subjective wellbeing among ninth-grade students attending state schools in Canoas, Brazil

During adolescence, body image is linked to subjective well-being. This study aimed to identify variables related to overall well-being (life satisfaction, health perception, happiness, and optimism) that discriminate between teenagers who are satisfied with body image and those who are dissatisfied. A cross-sectional, school- based study was conducted involving a sample of 1,460 ninth-grade students attending state schools in Canoas in the State of Rio Grande do Sul, Brazil. The following instruments were used: a sociodemographic questionnaire; the Economic Classification Criteria Brazil; the Body Shape Questionnaire; the Brief Multidimensional Students' Life Satisfaction Scale; the Happiness Measures; and health perception and perceived optimism. The data was analyzed using univariate analysis and multiple discriminant analysis. A total of 1,091 participants (74.7%) were satisfied with their body image. The variables that contributed most to the discrimination between groups were sex (0.680), self satisfaction (0.644), health perception (0.630), and level of happiness with health (0.601). Adopting an approach where having a positive body image is seen as a key element of mental and physical health can help make health care services more accessible to adolescents and promote more effective and less regulatory care.

Imagem corporal de adolescentes do sexo feminino e sua associação à composição corporal e ao comportamento sedentário

Resumo O objetivo deste artigo é avaliar a imagem corporal e sua associação à composição corporal, indicadores antropométricos e comportamento sedentário de adolescentes do sexo feminino. Estudo transversal com adolescentes do sexo feminino de Viçosa, MG. A imagem corporal foi avaliada por meio do Body Shape Questionnaire (BSQ) e pela Escala de Silhuetas. O percentual de gordura (%GC) e outros parâmetros antropométricos foram aferidos. O comportamento sedentário (CS) foi avaliado a partir da soma do tempo de tela (TT) e do tempo de celular (TC). A amostra foi composta por 274 adolescentes, a maioria com IMC adequado (81,6%), porém, 53,9% apresentaram o % GC elevado. Mais da metade das adolescentes apresentaram o CS elevado, 68,2% com o TT e 54,7% com o TC acima de 2h. A insatisfação corporal manifestou-se em 45,7%, e 50,2% desejaram uma silhueta diferente da atual. O perímetro da cintura (PC) (OR = 11,94, IC = 2,744 – 51,728) e a relação cintura-estatura (RCE) (OR = 10,535, IC = 3,109 – 35,698) foram as medidas mais associadas à insatisfação corporal. Todas as medidas de composição corporal apresentaram associação significativa com a insatisfação corporal, sendo o PC e o RCE os fatores mais condicionantes. O CS mostrou-se elevado, no entanto, não se associou com a avaliação negativa da imagem corporal.

Insatisfação corporal em adolescentes e fatores associados

O objetivo do estudo foi avaliar a insatisfação corporal entre os adolescentes, assim como os fatores associados. Avaliou-se 345 adolescentes de 10 a 14 anos. Foram aferidas as variáveis: peso, altura, circunferência da cintura, circunferência braquial, percentual de gordura, glicemia de jejum, triglicerídeos, colesterol total, maturação sexual e pressão arterial. A imagem corporal foi avaliada por meio da escala de imagem corporal. Foram realizados os testes t de Student ou Kruskal Wallis, calculou-se a Razão de Prevalência e os fatores associados à insatisfação corporal foram verificados por regressão de Poisson, para avaliar a adequação do modelo final, utilizou-se o teste de Qui-quadrado. Observou-se que 32,6% dos adolescentes apresentavam excesso de peso, desses, 13,1% foram classificados como obesos, segundo o IMC por idade. Apenas o percentual de gordura corporal foi estatisticamente diferente entre os sexos. A prevalência de insatisfação foi elevada (sexo feminino: 81,02% e masculino: 75,62%) e apresentou associação, em ambos os sexos, com o IMC, percentual de gordura corporal e circunferência da cintura. Nas meninas, também foi obtida associação com a glicemia. Já nos meninos, com a circunferência braquial e circunferência muscular braquial. Após ajuste do modelo a insatisfação manteve-se associada no sexo feminino com as variáveis: circunferência da cintura e glicemia. Nos meninos, com a gordura corporal e IMC. Concluiu-se que apesar da maioria apresentar o peso adequado, muitos adolescentes estavam insatisfeitos com seus corpos. Os achados também apontam que essa insatisfação atinge ambos os sexos e idades.

Body Weight Concern and Belief among Adolescent Egyptian Girls

BACKGROUND

Body weight concern and belief in adolescent females are of great importance. They are the keys to successful dietary interventions including dietary habits' modifications to practice a healthy diet. This critical phase of transition from childhood to adulthood is the most sensitive stage of behavioural rectification.

AIM

This study was conducted with the aim to figure out the prevalence of body image dissatisfaction and the association of body image satisfaction and believe with body mass index in adolescent girls aged 16-18 years.

MATERIAL AND METHODS

Two hundred and three Egyptian adolescent females were enrolled in this cross-sectional study. Their mean age was (17.4 ± 0.64) years old. Self-administered questionnaires about the students' body satisfaction and weight belief were answered by the candidates. Their body mass index was calculated. Also, sociodemographic data were collected. Data were analysed using SPSS software version 16.0. Chi-square test was conducted for the variables.

RESULTS

Sixty-eight percent of the students were within normal weight, 3.3% were underweight, while 18.2% and 10.5% were overweight and obese respectively. Body dissatisfaction was prevalent among 37.4%. The prevalence of body dissatisfaction was higher in both obese and underweight candidates reaching (93.8% and 80%) respectively. This reflects students' awareness of their body shape.

CONCLUSION

More than one-third of adolescent females were dissatisfied with their body image. The subjective belief about self-body image matched the objective Body Mass Index measurements.

Simultaneidade de fatores de risco comportamentais para doença cardiovascular em estudantes universitários

RESUMO: Objetivo: Analisar a prevalência e os fatores associados à simultaneidade de quatro fatores de risco comportamentais - inatividade física, elevado consumo de gorduras, consumo abusivo de álcool e tabagismo - para as doenças cardiovasculares (DCV) em estudantes de graduação da Universidade Federal do Rio Grande, Rio Grande, Rio Grande do Sul, Brasil. Métodos: Estudo de delineamento transversal. Foram analisadas variáveis sociodemográficas, o hábito de tomar café da manhã, a satisfação com a imagem corporal, o índice de massa corporal (IMC) e a autopercepção de saúde. O desfecho foi a simultaneidade de fatores de risco para as DCV. Foi realizada regressão logística ordinal, extraindo as razões de odds com os respectivos intervalos de confiança de 95% (IC95%) e valores p. Resultados: A amostra foi composta por 1.123 estudantes (taxa de resposta de 66,0%); desses, 24,7% apresentavam 2 fatores de risco ou mais. Na análise ajustada, apresentaram associação estatisticamente significativa (p < 0,05) com o desfecho as variáveis escolaridade materna intermediária, não ter o hábito de tomar café da manhã e autopercepção de saúde ruim/regular. Conclusões: Os achados deste estudo indicam uma importante prevalência de estudantes com simultaneidade de dois ou mais fatores de risco. Foi possível traçar quais são os grupos mais susceptíveis a apresentar maior número de fatores, ressaltando a associação com a falta de hábito de tomar café da manhã e a autopercepção de saúde ruim/regular.

Uso de redes sociais, influência da mídia e insatisfação com a imagem corporal de adolescentes brasileiras

Métodos Estudo transversal realizado com meninas adolescentes estudantes de escola pública e de uma organização não governamental da capital e do interior de São Paulo. Além de variáveis sociodemográficas e antropométricas, a avaliação da (IC) foi realizada pela Escala de Silhuetas Brasileiras. A influência da mídia foi avaliada pela subescala 1 de internalização geral da Escala de Atitudes Socioculturais em Relação à Aparência (SATAQ-3). Por fim, foram aplicadas perguntas sobre a frequência de acesso às mídias sociais e possível influência delas na IC. Resultados Participaram 212 meninas (14,8; DP 1,69 anos), sendo a maioria eutrófica (65,1%), pertencentes às classes sociais D e E, com escolaridade materna correspondente ao ensino médio completo; 85,8% estavam insatisfeitas com a IC; a maioria desejava uma silhueta menor. As meninas que escolheram figuras menores como desejadas apresentaram valores superiores na SATAQ-3 (p < 0,001). O acesso diário maior de 10 vezes ao dia ao Facebook e Instagram aumentou a chance de insatisfação em 6,57 e 4,47 vezes, respectivamente. Conclusão As mídias, incluindo as redes sociais, estão associadas à insatisfação da IC de meninas adolescentes.

STUDY OF BODY IMAGE IN PROFESSIONAL DANCERS: A SYSTEMATIC REVIEW

ABSTRACT Body image is multidimensional, dynamic, and entirely linked to the body in motion, which entails relevant bodily concerns in the routine of professional dancers, who need to maintain their body aesthetics constantly. The objective was summarizing the scientific production on the body image of professional dancers and to understand how they perceive it. This review is composed by seven studies that investigated professional dancers of classical ballet, jazz and contemporary dance. The results demonstrate that even though they are lean and had appropriate body mass index, professional dancers are dissatisfied with their body and wish to be thinner, that is, professional dancers constitute a risk group for the development of eating disorders.

Factors Associated With Body Image Perception Among Brazilian Students From Low Human Development Index Areas

This study aimed to evaluate sociodemographic, behavioral, and individual factors associated with body image perception in a sample of adolescents from schools in low Human Development Index areas in Brazil. This cross-sectional study included 609 boys and 573 girls (aged 11–17 years). Body image perception (nine-silhouettes scale) and sociodemographic, behavioral, and individual variables were included. Multinomial logistic regression analysis was used. Most boys (76.9%) and girls (77.5%) were dissatisfied with their body image. Body mass index status and healthy body image evaluation were significantly associated with body image dissatisfaction in both boys and girls ( p < .001), and daily fruit consumption was associated with body image dissatisfaction only in boys ( p = .035). Education and health care focused on body image can pay special attention to young people from vulnerable areas with unhealthy nutritional status and focus on strategies that enable improving the perception of a healthy body and a healthy diet.

Relationship Among Body Image, Anthropometric Parameters and Mental Health in Physical Education Students

Background

The prevalence of body image dissatisfaction (BID) is currently high. Given that psychological well-being is associated with the body measurements imposed by esthetic standards, BID is an important risk factor for mental disorders.

Objective

Identify the prevalence of BID, and compare anthropometric and mental health parameters between individuals satisfied and dissatisfied with their body image.

Method

A total of 140 university students completed the silhouette scale to screen for BID. Anthropometric measures, body mass index (BMI), waist circumference (WC) and body fat percentage (BFP) were used. To investigate mental health, The State-Trait Anxiety Inventories (STAI-S and STAI-T), Profile of Mood States (POMS) scale and Quality of Life (QOL-36) questionnaire were used to investigate mental health. The Student’s t-test was applied to compare anthropometric and mental health parameters.

Results

67.1% of university students exhibited BID. There was a significant difference (p = 0.041) in BF and WC (p = 0.048) between dissatisfied and satisfied individuals. With respect to mood states, significant differences were observed for anger (p = 0.014), depression (p = 0.011), hostility (p = 0.006), fatigue (p = 0.013), mental confusion (p = 0.021) and total mood disturbance (TMD) (p = 0.001). The mental aspect of QOL was significantly higher (p = 0.001) in satisfied university students compared to their dissatisfied counterparts.

Conclusion

BID was high and it seems to be influenced by anthropometric measures related to the amount and distribution of body fat. This dissatisfaction may have a negative effect on the quality of life and mood state of young adults.

Dissatisfaction with body image among adolescent students: association with socio-demographic factors and nutritional status

This article seeks to determine the prevalence of dissatisfaction with body image and its association with socio-demographic factors and nutritional status among adolescents. The following socio-demographic data, anthropometric variables, and perception of body image (n = 660) were collected. The prevalence of dissatisfaction with body image was 71.4%. Girls wished to reduce the size of their body silhouette, whereas boys wished to increase it. The desire to reduce body size was positively associated with female gender, with increased waist circumference and with excess weight. On the other hand, the desire to increase body size was negatively associated with the female gender and waist circumference, and was positively associated with ages 16, 17 and 18 + 19 years. Dissatisfaction with body image is highly prevalent among adolescents, though it is manifested differently in boys and girls. Increased abdominal fat, excess weight and female gender were predictors of dissatisfaction due to excess weight, and male gender and advanced age were predictors of dissatisfaction due to thinness.

Teasing and weight-control behaviors in adolescent girls

OBJECTIVE:

To analyze the association between weight teasing, body satisfaction and weight control behaviors.

METHODS:

Cross-sectional study based on adaptation and validity research of a North American questionnaire for adolescent girls about physical activity, nutrition, body image, perceptions, and behaviors. The variables used to conduct the study were weight control behaviors, body satisfaction and presence of teasing by family members. Descriptive analyses were carried out by chi-square test, being significant p<0.05.

RESULTS:

A total of 159 adolescent girls, with 16.2±1.3 years old were enrolled in this study. Of the total, 60.1% reported that family members did not tease them. The teasing was associated with weight dissatisfaction (p<0.001), body shape (p=0.006), belly (p=0.001), waist (p=0.001), face (p=0.009), arms (p=0.014) and shoulders (p=0.001). As a consequence, there was association with unhealthy weight control behaviors (p<0.001), vomiting (p=0,011), diet (p=0.002) and use of laxatives (p=0.035).

CONCLUSIONS:

The teasing about body image by family members was associated with risk for unhealthy weight control behaviors in female adolescents.

Development and aetiology of body dissatisfaction in adolescent boys and girls

This longitudinal study aims to describe the development of body dissatisfaction (BD), measured with the Contour Drawing Rating Scale, between the ages of 14 and 18, and to identify factors associated with BD at age 18, among 413 adolescents. Between the ages of 14 and 18, the proportion of girls wanting to be thinner increased, although it remained unchanged among boys. A ratio of 1:2 girls and 1:5 boys reported having seriously tried to lose weight. Factors associated with BD in girls at age 18 were (1) wanting to be thinner, (2) body mass index (BMI), (3) weight control behaviours and (4) negative comments about weight. Factors associated with BD in boys at age 18 were (1) wanting to be thinner or bigger, (2) BMI, (3) having experienced sexual intercourse and (4) negative comments about weight. The high prevalence of BD and weight-related concerns suggest a need for early interventions.

Distinguishing hyperhidrosis and normal physiological sweat production: new data and review of hyperhidrosis data for 1980-2013

BACKGROUND

Hyperhidrosis is a condition in which the production of sweat is abnormally increased. No objective criteria for the diagnosis of hyperhidrosis exist, mainly because reference intervals for normal physiological sweat production at rest are unknown.

OBJECTIVE

The main objective of this study was to establish reference intervals for normal physiological axillary and palmar sweat production.

METHODS

Gravimetric testing was performed in 75 healthy control subjects. Subsequently, these results were compared with findings in a cohort of patients with hyperhidrosis and with the results derived from a review of data on hyperhidrosis published between 1980 and 2013.

RESULTS

Approximately 90% of the controls had axillary and palmar sweat production rates of below 100 mg/5 min. In all except one of the axillary and palmar hyperhidrosis studies reviewed, average sweat production exceeded 100 mg/5 min.

CONCLUSIONS

A sweat production rate of 100 mg/5 min as measured by gravimetric testing may be a reasonable cut-off value for distinguishing axillary and palmar hyperhidrosis from normal physiological sweat production.

Does nutritional status interfere with adolescents' body image perception?

Adolescents' body image (BI) may not match their nutritional status. This study selected representative sample of healthy adolescents aged between 12 and 18 from public and private schools. Anthropometric measures were performed in order to calculate the body mass index (BMI) percentile. The silhouette scale proposed by Childress was used to evaluate BI, making it possible to assess BI satisfaction and BI distortion. The sample was composed of 1168 adolescents with a mean age of 14.7 years; 52.9% were female, 50.9% were fair-skinned, 62.4% had consumed or still consume alcohol and 67% attended public school. Male adolescents presented more overweight and obesity (28.4%) (p<0.05) than the female (17.1%). It was observed that 69.4% were dissatisfied with BI, 91.1% of the obese and 69.8% of those with overweight wished to lose body weight and 82.5% of those underweight wished to gain body weight. BI distortion was identified, since 35% of the adolescents who were underweight did not regard themselves thin, 39.1% of the overweight individuals and 62.1% of the obese did not see themselves in their adequate classifications. Adolescents with overweight/obesity were those who presented higher dissatisfaction with BI, mainly the females. Male individuals presented a greater wish of gaining weight. BI distortion was present in adolescents of all classes of BMI percentile.

Percepção da imagem corporal e fatores associados em idosos residentes em município do nordeste brasileiro: um estudo populacional

O objetivo do artigo é verificar a percepção da imagem corporal e fatores associados em idosos residentes em Campina Grande (PB). Trata-se de um estudo transversal, de base populacional e domiciliar, com indivíduos de 60 anos ou mais, de ambos os sexos. A percepção da imagem corporal foi considerada variável dependente para fins de análise e de estudo das possíveis associações. As variáveis independentes avaliadas foram: grupo etário, estado nutricional, número de doenças, percepção de saúde e prática de atividade física regular. Para identificar os fatores associados foram realizadas análises de regressão univariada e multivariada, por meio do SPSS 17.0. Foram avaliados 806 idosos. Os homens apresentaram maior satisfação com a imagem corporal quando comparados às mulheres, e idosos mais velhos apresentaram-se mais satisfeitos que idosos mais jovens. Entre os fatores relacionados à insatisfação nas mulheres, o baixo peso e sobrepeso/obesidade estavam relacionados a um risco aumentado de insatisfação. Entre os homens, idades avançadas constituíram fator de proteção para insatisfação, enquanto baixo peso e sobrepeso/obesidade foram fatores de risco para insatisfação. Os resultados sugerem possível influência do estado nutricional na percepção da imagem corporal, interferindo negativamente na percepção da imagem.

[Body image of adolescents in rural cities]

The scope of this article is to evaluate the body image of adolescents from rural cities and its relationship with nutritional status, sex and the adolescent phase. Adolescents of both sexes participated in the cross-sectional study. Body image was evaluated through the Body Shape Questionnaire (BSQ) and the Figure Rating Scale (FRS) for adolescents. Weight and height were measured for the evaluation of body mass index (BMI). Stages of adolescence were classified by age. Descriptive and inferential statistical analyses were conducted. Four hundred and forty-five adolescents (190 boys and 255 girls), with a mean age of 16.44 comprised the sample. Higher risk of body dissatisfaction was found among overweight and obese participants (BSQ: OR = 3.359 p < 0.001; ESA: OR = 1.572 p = 0.387) and the female sex (BSQ: OR = 3.694 p < 0.001; ESA: OR = 0.922, p = 0.840). Participants from the intermediary and final stages of adolescence revealed a lesser risk of dissatisfaction compared to those from the initial phase. Body dissatisfaction was related to overweight and obesity, to the female sex and to the initial period of adolescence. Intervention research is required to control the factors that influence excessive adolescent body dissatisfaction.

[Silhouette scales and body satisfaction in adolescents: a systematic literature review]

The purpose of this study was to summarize studies on adolescents' body satisfaction, focusing on the use of silhouette scales. A systematic review was carried out on MEDLINE, LILACS, SciELO, and in unpublished papers. The final analysis included 36 studies. The majority adopted the scale proposed by Stunkard et al., self-administered, presented in ascending order and on a single sheet of paper. Most studies compared characteristics on satisfaction and dissatisfaction, used the chi-square test, and did not test for confounding. Among 18 studies included in the meta-analysis, prevalence of body dissatisfaction ranged from 32.2% to 83%. The review showed wide heterogeneity between studies (p-value = 0.000; I(2) = 87.39) even after sub-group analysis and the absence of relevant information for proper comparison of studies. The article concludes by recommending greater rigor in application of the scales and presentation of study methods on body satisfaction assessed by silhouette scales, in addition to new methodological studies and those that elucidate factors related to body satisfaction.
