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

[Social representations of the body by adolescents: qualitative systematic review]

The scope of this article is to identify adolescents' social representations of the body and how the issue of black bodies has been discussed. This is a systematic review whose searches took place in August 2023 in PubMed/MEDLINE, SciELO, Scopus, Web of Science, PsycInfo, PePSIC, BVS, and in the BDTD and OATD portals. The ten studies included pointed to a body whose central constituent is body appearance, the adolescents' appreciation of hegemonic aesthetic standards, the influence of the body on acceptance among peers, and the search for the desired body. As well as the incipient debate about the racial issue around the representations of the body was verified. Two studies deepen the discussion on this issue, exposing the exaltation of miscegenation and sexism present in stereotypes around the body of black women. Thus, it is clear that the body is conceived by young people as an important mediator of behavior, social relations and an instrument for expressing identities Given these social expectations, teenagers desire a white, thin, curvy and toned body. As well, there is a gap regarding characteristics and values associated with the black body.

Relationships between media influence, body image and sociocultural appearance ideals in Latin America: A systematic literature review

The rapidly growing body of research investigating media influence on body image in Latin America has not been previously comprehensively synthesised. We systematically reviewed studies of the relationships between media use/influence, body image, and sociocultural appearance ideals in Latin America (CRD42021254607). We searched PsycINFO/Medline, Pubmed, Web of Science, ERIC, Scopus, ProQuest Dissertations, SciElo, and LILACS for quantitative and qualitative peer-reviewed articles and doctoral theses in English, Spanish, and Portuguese. Research conducted in Latin America, published 1991-2023, measuring a) media use/influence, and b) body image or appearance ideals was included. 68 articles met inclusion criteria, and quality appraisal concluded that most were of medium/high quality. A narrative review found consistent quantitative relationships, stronger in women than men, between media use/internalisation of media ideals and both body dissatisfaction and thinner appearance ideals. In contrast, participants in qualitative studies acknowledged media influence on their body image, but perceived greater influence from family and peers. Limitations included a predominance of cross-sectional research from Brazil and Mexico with adolescents and young adults. Additional longitudinal, experimental, and interventional work from elsewhere in Latin America is needed, recruiting more diverse samples and assessing more culturally salient appearance aspects (e.g., skin tone and hair texture).

Body satisfaction of lesbian and bisexual Brazilian women: Indicators of self-esteem, physical appearance perfectionism, and identity processes

This article examined the association between body satisfaction and sexual identification among lesbian and bisexual women, since these factors help to understand the cultural background of the objectification of female bodies in Latin cultures. Women who identify as lesbian (N = 239) and bisexual (N = 60) completed demographic data and measures of self-esteem, physical appearance perfectionism, lesbian and bisexual identity difficulties, and body satisfaction. We performed a three-stage hierarchical multiple regression to explore how variables relate to body satisfaction. The results suggest that self-esteem plays a key role, explaining 20.4% of the variance in body satisfaction. We discussed the psychosocial and cultural aspects involved in the relationship between the variables, and social and aesthetic pressures on women's bodies. This study contributes to discussions on psychosocial aspects associated with body satisfaction among Brazilian lesbian and bisexual women.

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.

The unsustainable weight of self-image: (re)presentations in the spectacle society

This study aimed to identify adolescent self-image in the face of a society forged by perfect image-body standards, understanding the influence of social relationships and the media in constructing their identities. This is qualitative research based on Oral History involving 13 male and female and adolescents aged 15-19, students from a public school in Minas Gerais. We employed interviews with a semi-structured roadmap to collect data, which were later interpreted by thematic content analysis proposed by Bardin. The findings were arranged into two categories: 1 - Self-image in the construction of the adolescent's identity and 2 - The aesthetic ideal of the spectacle society. The reports show a strong influence of technology in forming their identities and possible consequences that the search for a spectacular image to meet the aesthetic standards of the virtual or real world can bring to adolescents. This idealized self-image reveals the new way of being and living, the values, and the fragile and superficial relationships in the spectacle society.

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.

Repercussions of Social Networks on Their Users’ Body Image: Integrative Review

Abstract This integrative review of literature followed the PICO strategy to investigate the repercussions of the use of social networks on the body image of their users. PubMed, LILACS, PsycINFO and SciELO databases were included as well as articles published between January 2006 and February 2019. Thirty-three articles were analyzed, which compose the corpus of this review. The studies revealed that social networks have a predominantly negative repercussion on the body self-image of their users, increasing levels of body dissatisfaction, also having a negative impact on mood and self-esteem. Added to this, social networks influenced the body type that users would like to have, translated by the lean body profile, considered a model of beauty.

Clustering of obesogenic behaviors and association with body image among Brazilian adolescents in the national school-based health survey (PeNSE 2015)

•

The co-occurrence of obesogenic behaviors is associated to body image indicators.

•

Risk behaviors combined may set the adolescent at risk for psychological health.

•

Adolescents in healthy clusters perceive themselves as having normal weight.

•

Girls engaging in healthy clusters are less likely to use pills to control weight.

This study aimed to examine the association between clusters of obesogenic behaviors and body image indicators among a population-based sample of Brazilian adolescents. Data from a cross-sectional country representative survey of 9th grade students (N = 102,301) were analyzed. Physical activity (PA), sedentary behavior (SB) and body image indicators (i.e. satisfaction, perception, value, and weight control attitudes and behaviors) were self-reported. Three clusters were previously validated with two-steps cluster analysis: “Health-promoting SB and diet”, “Health-promoting PA and diet”, and “Health-risk”. Multinomial and binary logistic regression were used to associate clusters with body image indicators. Adolescents in the healthier clusters were more likely to be satisfied/very satisfied with body image and perceive themselves as having normal weight than those in the “Health-risk” cluster. Boys in both health-promoting clusters were more likely to consider body image as being important/very important and perceive themselves to be thin/very thin. Adolescents in the “Health-promoting PA and diet” cluster were more likely to be trying to lose or gain weight than those in the “Health-risk” cluster. Girls in the “Health-promoting SB and diet” cluster had lower odds of adopting unhealthy weight control behaviors than those in the “Health-risk” cluster. The effect of obesogenic behaviors on distinct aspects of body image was confirmed and found to vary according to different synergies between adolescents’ health-related behavior. These findings provide important insights on the understanding of behavioral profiles which can be targeted to prevent unhealthy weight control behaviors and weight related disorders, especially among girls.

Use of Social Networks for Data Collection in Scientific Productions in the Health Area: Integrative Literature Review

Objective: To investigate evidence on the use of social networks to collect data in scientific productions in the health area. Material and method: An integrative literature review from primary studies indexed in the SciELO, PubMed, LILACS, Scopus, and Web of Science platforms. Results: 16 scientific articles were selected, of which nine focused on the use of WhatsApp; five, on the use of Facebook; and two, on employing Twitter to collect data in scientific productions. Growth was noted on the number of investigations associated to the use of social networks, although an important paradigm still exists related to the use to generate scientific evidence, resulting in a still low number of investigations on this theme. Conclusions: The health area needs to approach evermore the development of research associated to social networks, given that this would enable a viable and rapid intervention in obtaining responses, besides being a low cost and very promising tool for data collection.

Relação entre imagem corporal, atitudes para transtornos alimentares e estado nutricional em universitárias da área da saúde

RESUMO Objetivo Avaliar a relação entre a insatisfação da imagem corporal, atitudes para transtornos alimentares e o estado nutricional em universitárias da área da saúde. Métodos Estudo descritivo, transversal e quantitativo com 225 universitárias matriculadas em oito cursos da área da saúde. Para obtenção dos dados, utilizaram-se três instrumentos autoaplicáveis: o Body Shape Questionnaire (BSQ), o Eating Attitudes Test (EAT-26) e um questionário construído pelas pesquisadoras contendo os dados autorreferidos de altura, peso atual e peso desejado, curso e idade. O estado nutricional foi estabelecido segundo o cálculo do índice de massa corporal. Para análise dos dados, aplicou-se o teste qui-quadrado de Pearson, adotando-se o nível de significância de 5%. Resultados A média de idade foi de 22,65 anos e a de IMC, de 23,05 kg/m2, estando a maioria das universitárias em eutrofia (69,8%). Quanto ao peso desejado, 74,7% gostariam de pesar menos; dessas, 64,9% eram eutróficas. Conforme o BSQ, 51,1% das universitárias tiveram algum grau de insatisfação corporal, e a prevalência de atitudes indicativas de transtornos alimentares, de acordo com o EAT-26, foi de 21,8%. Houve associação estatisticamente significativa entre: IMC e BSQ (p < 0,001); IMC e EAT-26 (p < 0,005); BSQ e EAT-26 (p < 0,001). Ao relacionar a insatisfação da imagem corporal e atitudes de risco para transtornos alimentares, percebeu-se que 87,75% das universitárias com EAT positivo também apresentaram algum grau de insatisfação corporal. Conclusão Evidenciou-se a existência de relação entre a insatisfação com a imagem corporal, atitudes de risco para transtornos alimentares e estado nutricional de universitárias da área da saúde.
