Resumo O objetivo deste estudo é verificar a associação da prática de bullying com comportamentos de risco à saúde e qualidade de vida, em meninos e meninas adolescentes, da cidade de Maringá, Paraná. Uma amostra representativa de 1.020 adolescentes participou do estudo. O bullying, os comportamentos de risco à saúde, a percepção de qualidade de vida e a condição econômica foram avaliados por questionários autorreportados. Razões de chances com intervalos de confiança de 95% (IC95%) foram obtidas por meio da regressão logística binária e regressão logística ordinal, bruta e ajustada, adotando-se p<0,05. Os meninos praticantes de bullying tiveram 2,2 (IC95%=1,4-3,4) e 2,0 (IC95%=1,2-3,2) vezes mais chance de consumir álcool e de realizar atividade física do que meninos que não praticam bullying. Meninas praticantes de bullying tiveram 2,1 (IC95%=1,3-3,5), 3,6 (IC95%=1,3-10,1), 1,8 (IC95%= 1,1-2,9) e 2,7 (IC95%=1,1-6,3) vezes mais chance de fumar, usar drogas ilícitas, ter vício em smartphone e ter uma pior qualidade do sono, além de possuir 60% mais chance de ter uma pior percepção de qualidade de vida, respectivamente, em comparação com meninas não praticantes. Ser praticante de bullying pode estar associado a comportamentos de risco à saúde, tanto para os meninos quanto para as meninas.

Resumen El objetivo de este estudio es verificar la asociación entre bullying escolar y conductas de riesgo para la salud y la calidad de vida en niños y niñas adolescentes de la ciudad de Maringá, Paraná. Participó del estudio una muestra representativa de 1.020 adolescentes. El bullying, las conductas de riesgo para la salud, la calidad de vida percibida y la situación económica se evaluaron mediante cuestionarios autoinformados. Los odds ratios con intervalos de confianza del 95% (IC95%) se obtuvieron mediante regresión logística binaria y regresión logística ordinal, cruda y ajustada, adoptando p<0,05. Los niños acosadores tenían 2,2 (IC95%=1,4-3,4) y 2,0 (IC95%=1,2-3,2) veces más probabilidades de consumir alcohol y realizar actividad física que los niños que no acosaban. Las niñas que practicaban bullying tuvieron 2,1 (IC95%=1,3-3,5), 3,6 (IC95%=1,3-10,1), 1,8 (IC95%=1,1-2,9) y 2,7 (IC95%=1,1-6,3) veces más probabilidades de fumar, consumir drogas ilícitas, tener adicción a los teléfonos inteligentes y tener peor calidad de sueño, además de tener un 60% más probabilidades de tener una peor percepción de calidad de vida, respectivamente, en comparación con las niñas no practicantes. El bullying escolar puede estar asociado con conductas de riesgo para la salud tanto de niños como de niñas y una peor calidad de vida para las niñas.

Abstract This study assessed the practice of bullying, health risk behavior and quality of life in adolescent boys and girls from the city of Maringá, Paraná. A representative sample of 1,020 adolescents participated in the study to assess the association between bullying, health-risk behavior, and quality of life factors through self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using both crude and adjusted binary and ordinal logistic regression, with a significance level of p<0.05. Male bullying perpetrators were 2.2 (95%CI=1.4-3.4) and 2.0 (95%CI=1.2-3.2) times more likely to consume alcohol and engage in physical activity compared to non-bullying males. Female bullying perpetrators were 2.1 (95%CI=1.3-3.5), 3.6 (95%CI=1.3-10.1), 1.8 (95%CI=1.1-2.9), and 2.7 (95%CI=1.1-6.3) times more likely to smoke, use illicit drugs, be addicted to smartphones, and have poorer sleep quality. These girls also had a 60% higher chance of having a worse perception of quality of life, respectively, compared to non-bullying females. The conclusion drawn is that bullying may be associated with health risk behaviors for both boys and girls.

RESUMO Objetivo: Analisar a associação entre a participação em exercícios físicos relacionados ao fitness (EFRF) e a insatisfação com a imagem corporal (IIC) em adolescentes e avaliar a interação entre os exercícios físicos e o estado nutricional nesta associação. Métodos: Estudo transversal realizado em 2015 com 799 adolescentes (10 a 16 anos) de 14 escolas públicas de Curitiba (PR), Brasil. A IIC foi avaliada por meio do Body Shape Questionnaire e da Escala de Silhuetas. A participação em EFRF foi avaliada pelo Questionário de Atividade Física para Adolescentes e classificada em “não pratica”, “pratica ≤300 minutos/semana” e “pratica >300 minutos/semana”. As regressões de Poisson e logística multinomial, ajustadas por sexo, maturação sexual e estado nutricional, analisaram a associação entre EFRF e IIC. Resultados: A prevalência de IIC foi de 28,3%; 52,4% dos adolescentes queriam reduzir a silhueta e 48,7% não praticavam a EFRF. Adolescentes que praticavam EFRF >300 minutos/semana tiveram prevalência 28% maior para algum nível de IIC (razão de prevalência — RP 1,28; intervalo de confiança de 95% — IC95% 1,08–1,52) e chance 46% menor de querer reduzir silhuetas (OR 0,54; 95IC% 0,35–0,82), comparados aos não praticantes. Não houve interação entre os EFRF e o estado nutricional na associação com IIC. Conclusões: Os adolescentes que praticam EFRF >300 minutos/semana estão mais propensos a apresentar algum nível de IIC e têm menores chances de reportar o desejo de aumentar silhuetas, independentemente do estado nutricional.

ABSTRACT Objective: The aim of this study was to analyze the association between participation in fitness-related exercises (FRE) and body image dissatisfaction (BID) in adolescents and evaluate the interaction between physical exercise and nutritional status in this association. Methods: A cross-sectional study was conducted in 2015 involving 799 adolescents (10–16 years old) from 14 public schools in Curitiba (PR), Brazil. BID was assessed using the Body Shape Questionnaire and the Silhouette Scale. The FRE was classified as “does not practice,” “practices ≤300 min/week,” and “practices >300 min/week” by the Physical Activity Questionnaire for Adolescents. Poisson and multinomial logistic regressions, adjusted for sex, sexual maturation, and nutritional status analyzed the association of FRE and BID. Results: The BID prevalence was 28.3%; 52.4% of the adolescents wanted to reduce their silhouettes; and 48.7% did not practice FRE. Adolescents who practiced FRE >300 min/week had a 28% higher prevalence for some level of BID (PR 1.28; 95%CI 1.08–1.52) and a 46% lower chance of wanting to reduce silhouettes (OR 0.54; 95%CI 0.35–0.82), compared to nonpractitioners. There was no interaction between FRE and nutritional status in association with BID. Conclusions: The adolescents who practice FRE >300 min/week are likely to have some level of BID and are less likely to report the desire to increase their silhouettes, regardless of their nutritional status.

RESUMO Objetivo: Examinar a associação entre vitimização por bullying e comportamentos de risco à saúde em adolescentes. Métodos: Uma amostra representativa de 1.020 adolescentes participou do estudo. As variáveis bullying, comportamentos de risco à saúde (tabaco, drogas, álcool, comportamento sedentário, uso de smartphone, nível de atividade física, sono) e situação econômica foram avaliadas por meio de questionários autorreportados. Razões de chance com intervalos de confiança de 95% (IC95%) foram obtidas por meio de regressão logística binária e regressão logística ordinal, bruta e ajustada (p<0,05). Resultados: As vítimas de bullying apresentaram maior probabilidade de fumar (OR 1,75; IC95% 1,28–2,40), consumir álcool (OR 1,43; IC95% 1,05–1,94), ter pior qualidade de sono (OR 1,94; IC95% 1,28–2,91) e apresentar mais comportamento sedentário (OR 1,43; IC95% 1,08–1,89) do que aqueles que não sofreram bullying. No entanto, as vítimas eram mais propensas a ter níveis elevados de atividade física do que os seus pares não vítimas de bullying (OR 1,66; IC95% 1,22–2,27). Conclusões: A vitimização por bullying esteve associada ao aumento da predisposição para a adoção de comportamentos de risco à saúde. Curiosamente, as vítimas também eram mais propensas a participar de atividades físicas.

ABSTRACT Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents. Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05). Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28–2.40), consume alcohol (OR1.43; 95%CI 1.05–1.94), have worse sleep quality (OR 1.94; 95%CI 1.28–2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08–1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22–2.27). Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.

RESUMO Objetivo: Realizar uma revisão sistemática e metanálise para verificar a associação de aspectos da prática esportiva com comportamentos de risco à saúde em adolescentes. Fontes de dados: Realizou-se uma busca sistemática de manuscritos eletrônicos da United States National Library of Medicine (PubMed)/ Medical Literature Analysis and Retrieval System Online (MEDLINE), Web of Science, Science Direct, and Scientific Electronic Library Online (SciELO), publicados de janeiro de 2015 a dezembro de 2022. Foram incluídos estudos que examinaram a associação entre o esporte e comportamentos de risco à saúde, com amostra composta de adolescentes com idades de 11 a 19 anos. Este estudo foi registrado na International Prospective Register of Systematic Reviews (PROSPERO) com número CRD42023392053. Síntese dos dados: Ao todo, 22 estudos preencheram os critérios de inclusão. A associação da prática esportiva com comportamento sedentário apresentou valores de razão de chances (odds ratio — OR) variando de 0,61 a 0,92, consumo de tabaco de 0,35 a 0,73, drogas ilícitas de 0,40 a 0,91 e redução do sono inadequado durante a semana de 0,57 (intervalo de confiança de 95% — IC95% 0,52–0,63) e finais de semana 0,79 (IC95% 0,69–0,89). Na metanálise, a prática esportiva teve associação significativa com o consumo de álcool para meninos (OR 1,36; IC95% 1,09–1,70) e esteve inversamente associada com o consumo de tabaco para meninos e meninas (OR 0,59; IC95% 0,56–0,61). Conclusões: Adolescentes que realizam prática esportiva tendem a apresentar menor ocorrência de comportamento sedentário, consumo de tabaco e de drogas ilícitas e quantidade de sono inadequada; e, na metanálise, os meninos apresentam valores mais elevados para o consumo de álcool e meninos e meninas valores mais baixos para o uso de tabaco.

ABSTRACT Objective: To conduct a systematic review and meta-analysis to verify the association of aspects of sports practice with health risk behaviors in adolescents. Data source: A systematic search was conducted of electronic manuscripts from the United States National Library of Medicine (PubMed)/ Medical Literature Analysis and Retrieval System Online (MEDLINE), Web of Science, Science Direct, and Scientific Electronic Library Online (SciELO) published from January 2015 to December 2022. Studies examining the association between sport and health risk behaviors in adolescents aged 11 to 19 years were included. This study was registered in the International Prospective Register of Systematic Reviews (PROSPERO) under number CRD42023392053. Data synthesis: In total, 22 studies fulfilled the inclusion criteria. The association of sports practice with sedentary behavior showed odds ratio (OR) values ranging from 0,61 to 0,92, tobacco use from 0,35 to 0,73, illicit drugs from 0,40 to 0,91, and reduced inadequate sleep on weekdays of 0.57 (95% confidence interval — 95%CI 0.52–0.63) and weekends 0.79 (95%CI 0.69–0.89). In the meta-analysis, sports practice was significantly associated with alcohol consumption for boys (OR 1,36; CI95% 1,09–1,70), and was inversely associated with tobacco use for boys and girls (OR 0,59; CI95% 0,56–0,61). Conclusions: Adolescents who practice sports tend to have lower occurrences of sedentary behavior, tobacco and illicit drug use, and adequate amounts of sleep; and, in the meta-analysis, boys present higher values for alcohol consumption and boys and girls present lower values for tobacco use.

ABSTRACT OBJECTIVE To verify whether parental physical activity and social support are associated with adolescents meeting physical activity recommendations. METHODS This is a cross-sectional study that selected 1,390 adolescents (59.6% girls) from Curitiba, Paraná, Brazil. The IPAQ (International Physical Activity Questionnaire), QAFA (Physical Activity Questionnaire for Adolescents), and ASAFA (Social Support for Physical Activity Practice in Adolescents) questionnaires were applied. Binary logistic regression was used to test the relationship among the study variables. RESULTS For boys, having parents who “always attend” (OR = 1.96; 95%CI: 1.16–3.32) and having parents or legal guardians who meet the PA recommendations (OR = 2.78; 95%CI: 1.76–4.38) were associated with meeting the PA recommendations. Odds were greater after adjusting for socioeconomic status (OR = 3.47; 95%CI: 1.73–6.96) and schooling level (OR = 4.20; 95%CI: 1.96–9.02). For girls, those with parents or legal guardians who “sometimes encourage them” (OR = 0.61; 95%CI: 0.37–0.98) had lower odds of meeting PA recommendations. These odds were higher after adjusting for socioeconomic status (OR = 2.11; 95%CI: 1.36–3.29) and schooling level (OR = 4.30; 95%CI: 2.41–7.69). CONCLUSIONS Boys and girls were more likely to meet PA recommendations daily by having parents who meet PA recommendations than by receiving parental social support. These results could help establish future interventions aimed at modifying behaviors related to PA in adolescents. crosssectional cross sectional 1390 1 390 1,39 59.6% 596 59 6 (59.6 Curitiba Paraná Brazil International Questionnaire, , Questionnaire) Adolescents, Adolescents Social applied variables boys always attend OR 1.96 196 96 95%CI 95CI CI 95 1.16–3.32 116332 16 3 32 2.78 278 2 78 1.76–4.38 176438 76 4 38 3.47 347 47 1.73–6.96 173696 73 4.20 420 20 1.96–9.02. 196902 1.96–9.02 . 9 02 1.96–9.02) sometimes them 0.61 061 0 61 0.37–0.98 037098 37 98 2.11 211 11 1.36–3.29 136329 36 29 4.30 430 30 2.41–7.69. 241769 2.41–7.69 41 7 69 2.41–7.69) 139 39 1,3 59.6 5 (59. 1.9 19 1.16–3.3 11633 2.7 27 1.76–4.3 17643 3.4 34 1.73–6.9 17369 4.2 42 19690 1.96–9.0 0.6 06 0.37–0.9 03709 2.1 21 1.36–3.2 13632 4.3 43 24176 2.41–7.6 13 1, 59.

Resumo Objetivos: estimar a prevalência de tempo de tela de adolescentes em três diferentes cenários e possíveis associações com sexo, maturação sexual, faixa etária, classe econômica e estado nutricional. Métodos: estudo transversal realizado com amostra representativa de 3.979 adolescentes da Grande Curitiba. O tempo de tela (televisão, computador e videogame) foi autorrelatado e categorizado em ≤2h/dia, >2 a ≤4h/dia e >4h/dia. A regressão logística ordinal testou as associações. Resultados: amostra com idade média de 14,60±1,88 anos, formada por 51,2% de meninas.A prevalência de tempo de tela >4h/dia foi de 89,3%. Meninas (OR=0,61; IC95%=0,49-0,76) e os grupos de idade mais velhos (“14 a 16 anos” OR=0,29; IC95%=0,22-0,39 e “17 a 19 anos” OR=0,11; IC95%=0,08-0,16) eram menos propensos a estar nos grupos de maior tempo de tela. Conclusões: o tempo de tela acima de quatro horas parece ser o mais prevalente entre os adolescentes. Meninas e adolescentes mais velhos são menos propensos ao maior tempo de tela.

Abstract Objectives: to estimate the prevalence of adolescents’ screen time in three different scenarios and possible associations with gender, sexual maturation, age group, economic class, and nutritional status. Methods: a cross-sectional study conducted with a representative sample of 3,979 adolescents from Greater Curitiba. Screen time (television, computer, and video game) was self-reported and categorized as ≤2h/day, >2 to ≤4h/day, and >4h/day. Ordinal logistic regression tested the associations. Results: the sample consisted of adolescents of 14.60±1.88 years old, most girls (51.2%). The prevalence of screen time >4h/day was 89.3%. Girls (OR=0.61; CI95%=0.49-0.76) and the older age groups (“14 to 16 years” OR=0.29; CI95%=0.22-0.39, and “17 to 19 years” OR=0.11; CI95%=0.08-0.16) were less likely to be in the groups of higher screen time. Conclusions: screen time above four hours seems to be the most prevalent among adolescents. Older girls and teens are less likely to have higher screen time.

Abstract Objective: This longitudinal study aimed to verify possible changes in the time spent in sedentary activities occurring as screen-time, educational, cultural, social, and transportation domains in a sample of Brazilian adolescents between 2015 and 2017. Methods: It is a longitudinal prospective study with 586 adolescents from 12 to 15 years old at the Baseline (2015) enrolled in 14 public schools from Curitiba, Brazil. The Adolescent Sedentary Activity Questionnaire assessed the time spent in sedentary activities in five domains (recreational screen-time, educational, cultural, social, and transportation). A series of linear random effects regressions analyzed changes in the sedentary time between 2015 and 2017, with p < .05. Results: Overall, 323 adolescents dropped out of the study resulting in a retention rate of 44.9%. The overall sedentary time remained stable from 2015 to 2017 (-3.98 min/day, 95%CI: -15.39; 7.42). The screen-time decreased (-22.22 min/day, 95%CI: -30.30; -14.15), and educational (8.29 min/day, 95% CI: 3.52; 13.06), cultural (3.41 min/day, 95% CI: 0.66; 6.15) and social sedentary activities (8.20 min/day, 95% CI: 2.06; 14.34) increased from 2015 to 2017. Conclusion: Significant reductions in screen-time were evidenced along with increases in time spent on other sedentary activities of educational, cultural, and social nature.

Resumo A presente investigação objetivou verificar modificações no consumo de cigarro e álcool em uma amostra de adolescentes do sistema estadual de ensino da cidade de Curitiba, Paraná, Brasil entre 2015 e 2017. Estudo longitudinal de coorte prospectivo realizado com 799 adolescentes, entre 11 e 15 anos. O consumo leve e excessivo de álcool e de cigarro foram avaliados através do questionário Youth Risk Behavior Survey (YRBS). Modificações do consumo de álcool e cigarro foram avaliadas através de modelos de Equação de Estimação Generalizável com distribuição de Poisson para obtenção de razões de taxas de incidência (RTI) com intervalos de confiança de 95% (IC95%). A variável “tempo” foi tratada como variável independente, juntamente com demais possíveis preditores (sexo, faixa etária, estado nutricional, nível socioeconômico, escolaridade do chefe da família, atividade física e tempo em tela). O consumo de cigarros (RTI= 1,32, IC95%= 1,02; 1,71), consumo leve (RTI= 1,32, IC95%= 1,13; 1,53) e excessivo de álcool (RTI= 1,21, IC95%= 1,04; 1,40) cresceram significativamente entre 2015 e 2017. O presente estudo denota que os adolescentes participantes desta investigação estão modificando seus comportamentos em direção a um estilo de vida menos saudável.

Abstract The scope of this study was to verify alterations in cigarette and alcohol consumption in a sample of adolescents from the state education system of the city of Curitiba in the State of Paraná between 2015 and 2017. It involved a longitudinal prospective cohort study conducted with 799 adolescents (11 to 15 years of age) between 2015 and 2017. The Youth Risk Behavior Surveillance System (YRBS) questionnaire evaluated mild and excessive alcohol and tobacco consumption. Modifications of alcohol and tobacco consumption were evaluated through Generalizable Estimating Equation (GEE) models with Poisson distribution to obtain Incidence Risk Ratios (IRR) with 95% confidence intervals (95%CI). The “time” variable was treated as an independent variable along with other possible predictors (gender, age bracket, nutritional status, socioeconomic level, head of household education, physical activity and screen time). Tobacco consumption (IRR= 1,32, 95%CI = 1,02; 1,71), mild (IRR= 1,32, 95%CI = 1,13; 1,53) and excessive (IRR= 1,21, 95%CI = 1,04; 1,40) alcohol consumption increased between 2015 and 2017. This study indicates that adolescents participating in this research are modifying their behaviors towards a less healthy lifestyle.

SUMMARY OBJECTIVE: The aim was to evaluate the changes in the prevalence of physical inactivity in the Brazilian adults from 2009-2017. METHODS: This study used a time-series research design based on the cross-sectional data of 462,498 Brazilian adults from 2009-2017. Participants were classified as physically inactive if they indicated not participating in physical activity in the last three months. The Prais-Winsten regression analyzed physical inactivity trends over time. RESULTS: The overall prevalence of physical inactivity was stable (p>0.05). Physical inactivity increased for women in four state capitals (annual growth rate: Goiânia 1.62%, Campo Grande 3.28%, Porto Velho 0.93%, and Vitória 2.09%) and decreased in one (annual growth rate: Rio Branco 4.50%). Physical inactivity decreased for men in four state capitals (annual growth rate: Campo Grande 4.72%, Natal 2.73%, São Luís 4.94%, and Rio Branco 2.95%). CONCLUSION: The physical inactivity among the Brazilian adults was stable between 2009 and 2017. Physical inactivity increased in women from Goiânia, Campo Grande, Porto Velho, and Vitória and decreased in women from Rio Branco and in men from Campo Grande, Natal, São Luís, and Rio Branco.

Resumo Introdução O esporte pode contribuir com a percepção de qualidade de vida dos adolescentes nessa fase de desenvolvimento. Objetivo Comparar os domínios da percepção de qualidade de vida de adolescentes, dos sexos masculino e feminino, praticantes de esporte no contraturno escolar (PE), praticantes de outra modalidade de exercício físico (PMEF) e não praticantes de exercício físico (NPEF). Método O estudo é transversal com delineamento ex post facto, com a população composta por adolescentes e com uma amostra de 374 sujeitos, dividida em três grupos. Para avaliar a percepção de qualidade de vida dos adolescentes, foi utilizado o questionário KIDSCREEN-52, e para a análise comparativa, o teste da Análise de variância (ANOVA) de um fator com post hoc de Scheffe. Resultados As comparações das dimensões de qualidade de vida (QV) mostraram que a prática esportiva é um importante fator para melhores percepções de QV e, consequentemente, uma melhor percepção de bem-estar, isto principalmente para o sexo masculino (F=5,38; 3,86; 4,79; 6,22; 7,93, para sentimentos; estado emocional; autopercepção; amigos; apoio social, respectivamente, p<0,05). Conclusão A prática esportiva, em especial na adolescência, merece destaque, já que os praticantes de esporte no contraturno apresentaram melhores percepções de QV nas diferentes dimensões analisadas.

Resumo O objetivo deste artigo é verificar a associação do estado nutricional e da atividade física com a percepção de satisfação da imagem corporal em uma amostra de adolescentes de Curitiba/PR. Compuseram a amostra 844 adolescentes entre 11 a 17 anos. O nível de atividade física foi avaliado pelo Questionário de Atividade Física para Adolescentes. A percepção da imagem corporal foi avaliada pela Escala de Figura de Silhueta e pelo Body Shape Questionnarie. A associação do estado nutricional e do nível de atividade física com a satisfação com a imagem corporal foi realizada através da regressão logística multinominal para obtenção da razão de chances com intervalo de confiança de 95% e p<0,05. O sobrepeso/obesidade esteve associado positivamente com a insatisfação com a imagem corporal (IIC) moderada e grave para meninas (RC: 6,20; IC95%: 2,62 - 14,66 e RC: 6,20; IC95%: 4,10 - 9,36) e meninos (RC: 1,95; IC95%: 1,06 - 3,59 e RC: 3,91; IC95%: 2,57 - 5,95) e com o desejo de diminuir a silhueta para meninos e meninas (RC: 4,86; IC95%: 3,37 - 7,00 e RC: 6,46, IC95%: 4,12 - 10,14). O nível de atividade física não se mostrou associado com a IIC. Adolescentes com sobrepeso e obesidade apresentam maior chance de reportarem IIC. A atividade física não esteve relacionada com a IIC.

Abstract The aim of this article is to verify the association between nutritional status and physical activity with the perception of body image satisfaction in a sample of adolescents from Curitiba, State of Paraná. The sample consisted of 844 adolescents of 11 to 17 years of age. The level of physical activity was evaluated by the Physical Activity Questionnaire for Adolescents. Body image perception was assessed by the Silhouette Shape Scale and the Body Shape Questionnaire. The association between nutritional status and level of physical activity with satisfaction with body image was performed through multinomial logistic regression to obtain the odds ratio with a 95% confidence interval and p < 0.05. Overweight/obesity was positively associated with moderate and severe body image dissatisfaction (BID) among girls (OR: 6.20; 95%CI: 2.62 - 14.66 and OR: 6.20; 95%CI: 4.10 - 9.36) and boys (OR: 1.95; 95%CI: 1.06 - 3.59 e OR: 3.91; 95%CI: 2.57 - 5.95) and with the desire to decrease the silhouette for boys and girls (OR: 4.86; 95%CI: 3.37 - 7.00 and OR: 6.46; 95%CI: 4.12 - 10.14). The level of physical activity was not associated with BID. Adolescents who are overweight and obese are more likely to admit to BID. Physical activity was not related to BID.
