Maternal Perception of the Child's Weight, Lifestyle Problems and Self-Efficacy to Deal with Them / Percepción materna del peso del hijo, problemas del estilo de vida y autoeficacia para manejarlos / Percepção materna do peso do filho, problemas do estilo de vida e autoeficácia para lidar com eles

Objetivos: associar a percepção materna do peso do filho (PMPF) e o estado nutricional dele. Descrever problemas comportamentais do estilo de vida do filho (PCEV) e autoeficácia materna (AE) para lidar com eles, verificar diferenças entre com e sem excesso de peso-obesidade (EP-OB) do filho e PMPF. Materiais e métodos: participaram 274 díades (mãe-filho em idade pré-escolar). A PMPF foi avaliada por meio de palavras e imagens. As mães responderam à Lista de Verificação de Comportamentos do Estilo de Vida. Peso e altura do filho foram medidos. Resultados: 18,8 % (n = 13) mães de filos com EP-OB e 78,8 % (n = 160) mães de filhos sem EP-OB tiveram PMPF adequada por palavras (X 2 = 77.759; gl = 1; p < ,001). Foi identificado que as mães de filhos com EP-OB referiram mais PCEV e menos AE. As mães de filhos com EP-OB tiveram que lidar com mais baixa AE e mais PCEV. Quando as mães percebem o EP-OB do filho por palavras, têm menos AE (U = 1118, p = ,015) e mais PCEV (F = 17,041, p = ,001). Conclusões: PMPF não adequada predominou em mães de filhos com EP-OB. Quando o EP-OB é percebido, mais PCEV e menos AE. Promover PMPF adequada particularmente em mães de filhos com EP-OB é recomendado. As imagens ajudam a reconhecer o EP-OB do filho mais do que a classificá-lo numa categoria.

Objetivos: asociar la percepción materna del peso del hijo (PMPH) y estado nutricional del hijo. Describir problemas conductuales del estilo de vida del hijo (PCEV) y autoeficacia materna (AE) para manejarlos, verificar diferencias conforme a con y sin sobrepeso-obesidad (SP-OB) del hijo y PMPH. Material y métodos: participaron 274 diadas (madre-hijo preescolar). La PMPH se evalúo por palabras e imágenes. Las madres contestaron la Lista de Verificación de Conductas del Estilo de Vida. Se midió peso y talla del hijo. Resultados: 18.8 % (n = 13) madres de hijos con SP-OB y 78.8 % (n = 160) madres de hijos sin SP-OB tuvieron PMPH adecuada por palabras (X2 = 77.759, gl = 1, p < .001). Las madres de hijos con SP-OB tuvieron que manejar más baja AE y más PCEV. Cuando las madres perciben el SP-OB del hijo por palabras, tienen menor AE (U = 1118, p = .015) y más PCEV (F = 17.041, p = .001). Conclusiones: Predominó PMPH no adecuada en madres de hijos con SP-OB. Cuando se percibe el SP-OB, más PCEV y menor AE. Se recomienda promover PMPH adecuada particularmente en madres de hijos con SP-OB. Las imágenes ayudan a reconocer el SP-OB del hijo más que a clasificarlo en una categoría.

Objectives: To associate the maternal perception of the child's weight (MPCW) and the child's nutritional status. To describe child's lifestyle behavior problems (CLBPs) and maternal self-efficacy (SE) to deal with them, as well as to verify differences according to children with and without overweight-obesity (OW-OB) and MPCW. Material and methods: There was participation of 274 dyads (mother-preschool child). MPCW was assessed through words and images. The mothers answered the Lifestyle Behaviour Checklist. The child's weight and height were measured. Results: 18.8 % (n = 13) of the mothers of children with OW-OB and 78.8 % (n = 160) of the mothers of children without OW-OB obtained adequate MPCW values through words (X2 = 77.759; DoF = 1; p < .001). It was identified that the mothers of children with OW-OB reported more CLBPs and less SE. When the child's OW-OB is perceived through words, there are more CLBPs (F = 17.041; p = .001) and less SE (U = 1,118; p = .015). Conclusions: Inadequate MPCW was predominant in mothers of children with OW-OB. When OW-OB is perceived, there are more CLBPs and fewer SE. It is recommended to promote adequate MPCW, particularly in mothers of children with OW-OB. Images assist in the identification of the child's OW-OB more than to classify it into a category.

Association between body weight perception and quality of diet in brazilian adolescents / Associação da percepção do peso corporal com a qualidade da dieta de adolescentes brasileiros

ABSTRACT Objective: To evaluate the association between body weight perception and quality of diet among Brazilian adolescents. Methods: The sample was composed of 71,740 adolescents aged from 12 to 17 years-old enrolled in the Study of Cardiovascular Risks in Adolescents (Estudo de Riscos Cardiovasculares em Adolescentes - ERICA), carried out during 2013-2014. Body weight perception was self-reported. Food consumption was assessed by food record and quality of diet index for Brazilian adolescents (DQIA-BR) was calculated, considering the balance, diversity, and diet composition. The quality of diet was compared according to weight perception for the entire sample and after stratification by nutritional status. Linear regression models were used to assess the association between body weight perception and quality of diet. Results: Among the studied adolescents, 14.7 and 30.3% reported to be underweight or overweight in relation to their desired weight, respectively. Those who perceived themselves as overweight had lower quality of diet (DQIA-BR=16.0 vs. 17.4 points; p<0.001). After stratification by BMI, adolescents with normal weight (DQIA-BR=15.3 points) or overweight (DQIA-BR=16.1 points), but who perceived themselves as overweight showed lower quality of diet when compared to their peers. In adjusted analysis, overweight perception (β= -0.51; 95%CI -0.77; -0.24) was associated to lower quality of diet. However, this association was no longer significant after stratification by BMI status. Conclusions: Body weight perception can influence the consumption of healthy foods and the quality of diet, especially for those who consider themselves overweight. However, this association is influenced by nutritional status.

RESUMO Objetivo: Avaliar a associação entre percepção de peso corporal e qualidade da dieta de adolescentes brasileiros. Métodos: A amostra estudada foi composta de 71.740 adolescentes de 12-17 anos participantes do Estudo de Riscos Cardiovasculares em Adolescentes (ERICA) realizado entre 2013 e 2014. A percepção do peso corporal foi avaliada por questionário autoaplicável; o consumo alimentar, por recordatório alimentar; e a qualidade da dieta pelo índice de qualidade da dieta de adolescentes brasileiros (IQDA-BR), considerando o equilíbrio, a diversidade e a composição da dieta. A qualidade da dieta foi comparada de acordo com a percepção do peso para toda a amostra e após estratificação por índice de massa corpórea (IMC). Modelos de regressão linear foram utilizados para avaliar a associação entre distúrbios na percepção do peso e qualidade da dieta. Resultados: Entre os adolescentes, 14,7 e 30,3% percebiam-se abaixo ou acima do peso, respectivamente. Aqueles que se percebiam acima do peso apresentaram menor qualidade da dieta (IQDA-BR=16,0 vs. 17,4 pontos; p<0,001). Após estratificação por IMC, adolescentes com peso normal (IQDA-BR=15,3 pontos) ou excesso de peso (IQDA-BR=16,1 pontos), mas que se percebiam como acima do peso, apresentaram pior qualidade da dieta se comparados ao demais. Em análise ajustada, perceber-se acima do peso (β= -0,51; intervalo de confiança de 95% - IC95% -0,77; -0,24) foi associado a pior qualidade da dieta, porém essa associação perdeu significância após a estratificação por IMC. Conclusões: A percepção do peso corporal parece influenciar o consumo de alimentos saudáveis e a qualidade da dieta principalmente daqueles que se consideram acima do peso, contudo essa associação é influenciada pelo estado nutricional.

Association of Weight Misperception with Unhealthy Diet-related Behaviors among University of the Philippines Manila Undergraduate Students

Objectives@#The study aims to determine whether there is an association of perceived weight status with unhealthy diet practices. @*Method@#An analytic cross-sectional study was conducted among 625 adult undergraduate students from U.P. Manila. The survey included questions regarding sociodemographic status, habits related to diet and weight management, and perceived body mass index (BMI). Actual BMI were obtained and calculated from actual anthropomorphic measurements. @*Results@#In the population surveyed, it was seen that 53.28% of the students accurately perceived their BMI status, 26.08% overestimated their BMI status, while 17.28% underestimated their BMI status. It was also seen that over-estimating of BMI status is more associated with unhealthy diet practices. Those who over estimated their BMI were 1.95 times more likely to skip meals (p=0.001) and 1.56 times more likely to engage in cutting of food (p=0.034). Physical activity was also seen to be associated with these practices. @* Conclusion@#Over-estimation of BMI may be linked to unrealistic goals in weight loss resulting in unhealthier diet-related habits.

Body Weight Misperception and Psychological Distress Among Children and Adolescents: The CASPIAN-V Study

OBJECTIVES: Misperception of weight status is a risk factor that affects psychological health. The aim of this study was to evaluate the association between weight misperception patterns and psychological distress among Iranian children and adolescents. METHODS: This was a cross-sectional nationwide study where data was collected from 14,440 students, aged 7–18 years who participated in the national school-based surveillance program (CASPIAN-V). The students’ weight perception and psychological distress were assessed by validated questionnaires. Weight misperception was classified as misperception of being either underweight or overweight with respect to actual weight. RESULTS: The rate of weight misperception in all study participants was 59.1%. In groups with a perception of being underweight or overweight, the risks of worthlessness, being worried, experiencing aggression, insomnia, or depression, were significantly higher than groups with an accurate weight perception (p < 0.05). The risk of anxiety in girls of normal weight who perceived themselves as underweight, decreased by 57% compared to girls with an accurate weight perception (OR: 0.43; 95% CI, 0.28–0.66). CONCLUSION: Weight misperception is highly prevalent among Iranian children and adolescents and is associated with their psychological health status. Appropriate education intervention needs to be developed to improve the children and adolescents’ perception of their body weight status.

Percepción del peso de una carga según composición corporal en asistentes de buses interurbanos / Perception of the weight of a cargo according to body composition in interurban bus assistants

Resumen: Con el objetivo de determinar la cantidad de peso correspondiente a distintas categorías lingüísticas según la percepción de la carga manipulada por trabajadores y en función de su composición corporal, se realizó un estudio en asistentes de buses interurbanos. Las variables estudiadas fueron: composición corporal expresada en términos de complexión física, esfuerzo percibido a través de la escala de Borg y prueba de confort mediante el diagrama de Corlett y Bishop. Los resultados indicaron que para la complexión física clasificada como estándar, los trabajadores consideraron como peso moderado 19,6 kg; para falta de ejercicios, un peso de 14,3 kg y para obesa, una cantidad de 10,5 kg; lo cual muestra una relación directa entre la composición corporal y la percepción del peso de la carga manipulada, ya que a medida que la complexión física es menos saludable la capacidad de levantar una carga disminuye significativamente. En esta investigación se comparan los resultados obtenidos con los límites de peso establecidos por la Ley N° 20.949 que regula en Chile el peso máximo de carga humana, con lo cual se demuestra que el peso percibido, incluso en la categoría extremadamente pesa do, se enmarca dentro de la ley actual.

Abstract: In order to determine the amount of weight corresponding to differ ent linguistic categories according to the perception of the burden handled by workers and based on their body composition, a study was carried out on interurban bus attendants. The variables studied were: body composition expressed in terms of physical constitution, perceived effort through the Borg scale and comfort test using the Corlett and Bishop diagram. The results indicated that for the physi cal constitution classified as standard, the workers considered as moderate weight 19.6 kg; for the lack of exercises constitution, a weight of 14.3 kg and for obese constitution, an amount of 10.5 kg; which shows a direct relationship between the body composition and the perception of the weight of the manipulated load, since as the physical complexion is less healthy the ability to lift a load decreas es significantly. This research compares the results obtained with the weight limits established by Law No. 20,949, which regulates the maximum weight of burden for humans to carry in Chile, which shows that the perceived weight, even in the extremely heavy cate gory, is framed within of the current law.

Body weight perception and body weight control behaviors in adolescents / Percepção do peso corporal e comportamentos para controle de peso em adolescentes

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

Resumo Objetivo: Verificar a associação da percepção (acima ou abaixo) do peso corporal esperado com os comportamentos para controle de peso em adolescentes. Métodos: Estudo transversal, feito com 1.051 adolescentes (15 a 19 anos) do ensino médio de escolas públicas estaduais. Foram coletadas informações sobre a percepção do peso corporal (variável dependente), comportamentos de controle de peso (iniciativa para mudar o peso, prática de exercícios físicos, comer menos ou cortar calorias, ficar 24 h sem comer, tomar medicamentos, vomitar ou tomar laxantes) e aferidas as medidas de massa corporal e estatura para cálculo do índice de massa corporal e classificação do status do peso. As associações foram testadas por meio da regressão logística multinomial. Resultados: Adolescentes de ambos os sexos com percepção do peso corporal abaixo do peso esperado apresentaram mais iniciativas para ganhar peso e aqueles que se percebiam acima do peso tiveram mais iniciativas para perder peso. Nos adolescentes que se percebiam acima do peso, o comportamento de não tomar medicamento esteve associado ao desfecho apenas nos rapazes (OR = 8,12), enquanto nas moças observou-se associação com comer menos, cortar calorias ou evitar alimentos gordurosos para perder ou para não aumentar o peso corporal (OR = 3,39). Adolescentes de ambos os sexos que faziam exercício físico tiveram maior chance de se perceber acima do peso (masculino OR = 2,00; feminino OR = 1,93). Conclusão: A percepção do peso acima e abaixo do peso esperado esteve associada aos comportamentos de controle de peso, nos quais, respectivamente, tinham mais chances de tomar iniciativas para perder e para ganhar peso.

Differences in Breast Cancer Screening Rates according to Obesity and Weight Perception among Korean Women

PURPOSE: This study was performed to elucidate whether the obesity or body image is a barrier to breast screening compliance in Korean women. METHODS: We included 54,017 women aged between 35 to 70 years from the Korea Community Health Survey (KCHS) 2014 dataset. To identify whether a mutual relationship exists between weight perceptions and breast cancer screening rates, the participants were divided into three groups according to the level of concordance between Body Mass Index (BMI) and a subjective body image. Descriptive analyses, a chi-square test, and multivariate logistic regression analyses were performed. RESULTS: After covariate adjustment, the screening rate of the overweight group was 1.09 times higher than the normal weight group (odds ratio [OR], 1.09; confidence interval [CI], 0.00–0.16; p=.038) and the severe obesity group was 1.20 times lower (OR, 0.83; CI, −0.36–0.00; p=.047). Weight misperception also had a significant influence on breast cancer screening. Especially, The overweight distortion group was less likely to undergo breast cancer screening (OR, 0.93; CI, −0.15–0.00; p=.037). CONCLUSION: Obesity and weight misperceptions are associated with lower compliance with breast cancer screening guidelines.

Estado nutricional, imagem corporal e associação com comportamentos extremos para controle de peso em adolescentes brasileiros, Pesquisa Nacional de Saúde do Escolar de 2015 / Nutritional status, body image, and their association with extreme weight control behaviors among Brazilian adolescents, National Adolescent Student Health Survey 2015

RESUMO: Introdução: Este estudo objetivou analisar a associação entre estado nutricional, percepção da imagem corporal e comportamentos extremos para controle de peso nos adolescentes. Metodologia: Estudo transversal analítico, realizado no Brasil a partir da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2015, com adolescentes de 13 a 17 anos. Estado nutricional e percepção da imagem corporal foram as variáveis independentes. As dependentes foram vômito ou uso de laxantes e uso de remédios e outras fórmulas para controle de peso nos últimos 30 dias. Modelos de regressão de Poisson foram empregados para associação, com uso de variáveis demográficas para controle. Resultados: 7,4% dos adolescentes (IC95% 6,7 - 8,2) relataram vômito ou uso de laxantes, sem diferença entre os sexos. A prevalência de uso de remédio e fórmulas foi maior entre meninos (7,8%; IC95% 6,6 - 8,9). A associação entre estado nutricional e comportamentos extremos não foi significativa; entretanto, a prevalência de vômito ou uso de laxantes foi 2,3 (IC95% 1,1 - 4,7) vezes maior em meninos e 5,3 (IC95% 3,3 - 8,6) vezes maior em meninas que se sentiam muito gordos(as), ao passo que uso de remédios e fórmulas foi 4,0 vezes (IC95% 2,3 - 7,1) maior em meninas que sentiam muito gordas. Conclusão: A percepção da imagem corporal parece ter maior influência na prática dos comportamentos extremos do que o estado nutricional. Estratégias envolvendo serviços de saúde e escolas têm grande potencialidade para ações que impactem positivamente na autoestima e na saúde dos estudantes.

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

Multilevel Analysis of Factors associated with Subjective Weight Perception among Normal Body Weight Adolescents based on the 2017 Korean Youth's Risk Behavior Survey (KYRBS)

PURPOSE: The present study is focused on understanding weight perception related with individual- and school-level multifactorial origins, underestimated and overestimated respectively, in normal body weight adolescents. METHODS: Using the 2017 Korea Youth Risk Behavior Web-based Survey data of 45,902 students from 799 secondary schools, a multilevel multinomial logistic regression analysis was performed where adolescents (level1) were nested within schools (level 2). RESULTS: At the school level, the average school body mass index (BMI, kg/m²) and physical education were associated with weight perception among both boys and girls. In boys, geographic areas were associated with weight underestimation. At the individual level, perceived economic status, weekly allowance, BMI (kg/m²), smartphone usage time (hrs/day) and perceived stress were associated with weight perception among both boys and girls. Age, paternal education, academic achievement and alcohol use were associated with weight perception among girls, while part-time job and physical activity were associated with weight perception among boys. CONCLUSION: Our findings underscore the importance of individual- and school-level environments in developing correct weight perception and have implications for school health education to establish healthy lifestyle behaviors for all adolescents.

Diferencias por sexo en el índice de masa corporal, percepción del peso corporal, satisfacción con el peso, desórdenes de la alimentación y estrategias para el control de peso en estudiantes de medicina y enfermería de la India / Diferenças por sexo no índice de massa corporal, percepção do peso corporal, satisfação com o peso, desordens da alimentação e estratégias para o controle de peso em estudantes de medicina e enfermagem da Índia / Gender Differences in Body Mass Index, Body Weight Perception, weight satisfaction, disordered eating and Weight control strategies among Indian Medical and Nursing Undergraduates

Objective. To assess gender disparity in body weight perception, Body Mass Index (BMI), weight satisfaction and role of depression among undergraduate Medical and Nursing students. Methods. A descriptive cross sectional descriptive study was conducted in conveniently selected medical (n=241) and nursing (n=213) students of Bangalore, South India. Data was collected using self-administered SCOFF questionnaires. Results. Our findings revealed that men had a significantly higher BMI than women (t=5.403, p<0.001). More number of women compared to men, perceived themselves as over weight (74.8%) and not satisfied with their weight status (81.6%). More men than women scored positively for disordered eating behaviors on SCOFF (45.4% vs. 31.1%) and EAT scale (16.5% vs. 8.7%). While, 48.2% of the women practice binge eating, 41.2% of the men practice it (p<0.004); more men (47.4%) than women (25.4%) exercised for more than sixty minutes (p<0.001) to control their weight. Conclusion. Findings indicate small differences between the genders that have to be taken in consideration in planning interventional programs to prevent eating disorders in this population. (AU)

Body-related Perspectives and Weight Control Methods of Korean-Chinese Nursing School Students in Yanbian, China: A Pilot Study

OBJECTIVES: This study aimed at identifying the current nutrition knowledge, body-related perspectives, and weight control behaviors of Korean-Chinese college students. METHODS: We conducted a pilot study by employing a healthy weight education program targeting Korean-Chinese nursing school students at the Yanbian University of Science and Technology in Yanbian, China. RESULTS: This pilot study included 40 participants (38 women and 2 men; mean age, 20.5 years). The current weight status of the participants was as follows: 7.9% underweight, 78.9% normal weight, 7.9% overweight, and 5.3% obese. However, nearly two-thirds of the participants were dissatisfied with their current body size (43.6% a little dissatisfied; 20.5% very dissatisfied). Fifty percent of the participants perceived their current body size as being either slightly fat (35.0%) or very fat (15.0%). The following unhealthy weight control methods were commonly used among the 24 participants who practiced weight control: (1) laxatives or diuretics (91.7%), (2) saunas or spas (87.5%), and (3) a one-food diet (79.2%). In addition, the nutrition knowledge of the participants increased by 24 points from 117 points (pretest) to 141 points (posttest) through the healthy weight education program. CONCLUSION: The findings of this study indicate an urgent need to educate Korean-Chinese college students on healthy weight control methods and body-related perspectives.

Body Weight Perception, Mental Health, and Weight Control Behavior in Normal Weight Adolescents: Based on the Korea National Health and Nutrition Examination Survey 2013-2015

PURPOSE: The aim of this study was to assess the body weight perception of adolescents and to investigate the difference between mental health and weight control behavior according to body weight perception. METHODS: Study data on 12–18 years old adolescents with normal BMI was obtained from the 6th Korea National Health and Nutrition Examination Survey (2013–2015). Rao-Scott Chi-square test and ANOVA were used for the analysis. RESULTS: The percentage of adolescents with a misperception of body weight was 43.3%, and their subjective health status (p=.013), stress perception (p=.001), and depression (p=.001) were worse than for adolescents who had the correct perception of their body weight. The percentage of adolescents who were trying to lose weight while perceiving their body weight as normal was 36.9%. Body weight control behavior had significant differences according to dietary intake (frequency of eating dinner (p=.015)), energy intake (p=.004), and carbohydrate intake (p<.001), but there was no significant difference according to exercise. CONCLUSION: Parents, school teachers, and nurses should make efforts to ensure that Korean adolescents perceive their body weight correctly, and prevent unhealthy weight control behaviors.

Gender Differences in the Effects of Weight, Weight Perception, and Weight Satisfaction on Depression in Adolescents

PURPOSE: This study aims to investigate gender differences in the association between depressive symptoms and weight, weight perception, and body satisfaction among Korean adolescents. METHODS: A secondary data analysis was performed on data from 33,374 adolescents who participated in the 2015 Adolescent Health Behavior Online Survey. They were classified as underweight, normal weight, or overweight/obese; weight perception was classified into perception of being underweight, normal weight, or overweight/obese; and weight satisfaction into desire to gain weight, satisfied, and desire to lose weight. RESULTS: Among boys, perception of being underweight (adjusted odds ratio [AOR]: 1.20, 95% confidence interval [CI]: 1.07~1.35) and desire to gain weight (AOR: 1.45, 95% CI: 1.30~1.62) were associated with depression. Among girls, perception of being overweight or obese (AOR: 1.18, 95% CI: 1.07~1.29) and a desire to lose weight (AOR: 1.30, 95% CI: 1.18~1.42) were associated with depression. CONCLUSION: Gender differences were observed in the association between weight perception and depression in adolescents. The perception of being underweight among boys and the perception of being overweight/overweight among girls were associated with depression. Thus, gender-specific intervention programs to correct weight perception and weight satisfaction are needed in order to relieve depressive symptoms in adolescents.

Percepção subjetiva do esforço em jogos oficiais de Futsal / Perception subjective effort in official Futsal games

O objetivo do presente estudo foi quantificar a intensidade dos esforços utilizando o método da PSE em partidas oficiais de futsal. A amostra foi constituída por 10 atletas do sexo masculino (16,5±2 anos) que participaram da etapa estadual dos Jogos Escolares da Juventude. Foi avaliado o comportamento da percepção subjetiva de esforço (PSE) em resposta à cinco jogos oficiais de futsal na categoria sub-17, sendo dois pela fase classificatória e três pela fase final da competição. A quantificação da carga interna foi determinada através do método da PSE da sessão (FOSTER et, al., 2001). Foram encontrados valores médios de 7,5 e 7,4 para as partidas da 1ª fase e 8,2, 8,7 e 8,9 para os jogos da fase final. Os resultados indicam cargas crescentes ao longo da competição, demonstrando que os jogos foram realizados com intensidades elevadas, compatíveis com intensidades de partidas de futsal analisadas utilizando outros indicadores, como frequência cardíaca e lactato. Pode-se concluir que a PSE é um método confiável para mensurar a intensidade dos esforços em partidas oficiais de futsal.(AU)

The aim of this study was to quantify the degree of effort using the method of PSE in official games of futsal. The sample consisted of 10 male athletes (16.5 ± 2 years) who participated in the state level of School Youth Games. The behavior of perceived exertion (RPE) in response to the five official games of futsal in the under-17 category was evaluated, two and three through the qualifying for the final stage of the competition. The quantification of the internal load was determined by the session SPE (Foster et, al. 2001) method. Average values of 7.5 and 7.4 for departures from 1st stage and 8.2, 8.7 and 8.9 for the finals matches were found. The results indicate increasing loads throughout the competition, demonstrating that the games were held at high intensities, consistent with intensities of futsal matches analyzed using other indicators such as heart rate and lactate. Can conclude that the PSE is a reliable method to measure the intensity of the efforts in official games of futsal.(AU)

Práticas alimentares e corpo obeso percepções e (con) vivências maternas

A obesidade infantil é um fenômeno contemporâneo e complexo que acomete as famílias no cenário mundial. As práticas alimentares, pelo olhar da Antropologia da Alimentação, envolvem, além dos processos nutricionais, as relações entre os processos socioculturais. Sabe-se que as mães das crianças obesas desempenham um papel importante e de influência durante as práticas alimentares de seus filhos e a não percepção sobre o estado nutricional das crianças pode dificultar a adesão ao tratamento. A proposta do presente estudo visou compreender as percepções e vivências maternas sobre as práticas alimentares e corpo obeso de crianças. Elegemos para o nosso estudo a pesquisa do tipo exploratória com a abordagem qualitativa e como vertente epistemológica, a Antropologia da Alimentação. Participaram treze mulheres, mães de crianças obesas na faixa etária de cinco a nove anos, do Município de Fortaleza-CE, no período de março a maio de 2015. Utilizamos a técnica da entrevista semiestruturada e a análise de discurso. As práticas alimentares das crianças obesas sob a óptica materna são descritas por meio de como a criança consome os alimentos, com o ato de comer rápido, em frente à televisão, comendo escondido e uma grande quantidade de alimentos, além do consumo de alimentos processados ricos em gordura, açúcares e sódio...

Childhood obesity is a complex contemporary phenomenon that strikes families worldwide. From the point of view of Anthropology of Food, eating practices involve the relations between sociocultural processes, besides nutritional processes. It is known that fat children’s mothers play an important, influential role in their kids’ eating practices, and their lack of perception of their kids’ nutritional situation may hinder the adherence to the treatment. This study aims to understand the mothers’ perceptions and experiences regarding their eating practices and their children’s obese bodies. We chose to carry out an exploratory research with a qualitative approach and, as an epistemological strand, the Anthropology of Food. Participants in the research were thirteen women, mothers of obese children ranging from five to nine years of age, from the city of Fortaleza, CE, Brazil, in the period of March to May, 2015. We used the semi-structured interview technique and discourse analysis. The obese children’s eating practices from the mothers’ point of view are described as the children consumes food, the act of fast eating, in front of the television, eating secretly a huge amount of food, as well as the consumption of processed food rich in fat, sugar and sodium...

The Association between Inappropriate Weight Control Behaviors and Suicide Ideation and Attempt among Korean Adolescents

Suicide is a leading cause of death among adolescents globally, and body weight is also a recognized reason for adolescent suicide. Therefore, we investigated the association between weight control behaviors (WCB) and suicide ideation and attempt, focusing on inappropriate weight control measures. We used data from the 2014 Korea Youth Risk Behavior Web-based Survey, representing a total of 35,224 boys and 34,361 girls aged 12 to 18 years. Adolescents were classified into groups based on WCB: appropriate WCB, inappropriate WCB, and no WCB. We performed logistic regression models to examine associations between WCB and suicide ideation and attempt, controlling for covariates. Both boys and girls with inappropriate WCB were more likely to report suicide ideation and attempt. Underweight and normal weight boys with inappropriate WCB were more likely to think or attempt suicide, and underweight girls with inappropriate WCB were also more likely to attempt suicide. Among five common WCB combinations, the combination of "regular exercise, fasting, eating less" was highly associated with suicide ideation and attempt. We confirmed that inappropriate WCB is associated with suicide ideation and attempt among Korean adolescents. Given the high incidence rate of suicide among adolescents and the adverse effect of inappropriate WCB, encouraging adolescents to control their weight in healthy ways is imperative.

Prevalence and Factors Affecting Body Shape Misperception among Korean Adult Women

PURPOSE: This study was done to investigate the prevalence and factors affecting body shape misperception among Korean adult women. METHODS: We analyzed raw data from the fourth Korean Longitudinal Survey of Women and Families, for 7,658 women over 20 years of age. For the multiple logistic regression model, the dependent variable was existence of misperception (yes/no). RESULTS: The prevalence of body shape misperception was 42.6% (overestimation 6.5%, underestimation 36.1%). Multiple logistic regression analysis revealed that age, education level, marital status, economic status and BMI were significantly associated with body shape underestimation. Education level and BMI were significantly associated with body shape overestimation. CONCLUSION: An effective obesity intervention program for women must reflect and monitor body shape perception as well as BMI.

Imagem corporal e comportamentos relacionados à saúde em adultos: Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil), 2008-2010 / Imagem corporal e comportamentos relacionados à saúde em adultos: Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil), 2008-2010

Introdução:A imagem corporal vem sendo cada vez mais abordada na comunidade científica devido a sua relação com a obesidade e seu impacto de influenciar os indivíduos a adotar um estilo de vida saudável. Existem indícios de que a satisfação com a imagem corporal pode estar relacionada a hábitos como a prática de atividade física, assim como a percepção da imagem corporal pode se relacionar com diversos fatores ainda não muito bem definidos. Objetivos: A presente tese tem dois objetivos, a saber: 1) verificar se a insatisfação com a imagem corporal e o estado nutricional, indicado pelo índice de massa corporal e razão cintura/estatura, são independentemente associados com a intensidade da atividade física e se tal associação se difere entre homens e mulheres e; 2) investigar e descrever quais fatores podem estar relacionados à inacurácia da percepção do peso por meio da imagem corporal entre adultos. Metodologia: A amostra deste estudo é proveniente da linha de base do Estudo Longitudinal de Saúde do Adulto, composta por 15.105 adultos e idosos, servidores públicos em universidades federais e centros de pesquisa, localizados em seis estados brasileiros: Minas Gerais, São Paulo, Rio de Janeiro, Espírito Santo, Bahia e Rio Grande do Sul. Dois artigos foram desenvolvidos, cada um referindo-se a um dos objetivos. No primeiro artigo, a variável resposta foi o nível de atividade física, categorizado em 3 intensidades. Em uma população de adultos (35-64 anos), por meio de regressão logística, estimou-se a chance de praticar atividade física na presença das variáveis satisfação com a imagem corporal, índice de massa corporal e razão cintura/estatura. No segundo artigo, por meio de regressão logística, foi investigado quais fatores sociodemográficos, comportamentais e psicológicos estavam relacionados à percepção do peso por meio da imagem corporal na vida adulta de acordo com o sexo(35-64 anos). Resultados: No primeiro artigo, a insatisfação com a imagem corporal esteve presente mesmo entre indivíduos de peso normal de ambos os sexos e foi associado com menores chances de praticar atividade física moderada em mulheres e atividade física intensa em homens. Homens e mulheres com obesidade central foram menos propensos a praticar atividade física de intensidade moderada ou alta. Homens com sobrepeso e obesidade eram mais propensos a relatar a atividade física vigorosa enquanto mulheres obesas eram menos propensas a relatar este nível de atividade física. O segundo artigo apresenta que, em ambos os sexos, idade avançada, ex-fumantes e compulsivos alimentares foram associados com maiores chances de superestimar o peso, enquanto que maiores níveis educacionais estiveram relacionados com menores chances de subestimar o seu peso. Entre os homens, as chances de subestimar o peso também foram maiores naqueles que trabalhavam em ocupações não-manuais/rotineiras e naqueles com depressão; e menor em quem consumia álcool excessivamente. Nas mulheres, a menor escolaridade foi associada a maiores chances de subestimação, mas sem um gradiente consistente. Conclusões: Nossos resultados revelam que os indivíduos participantes provindos do estudo multicêntrico ELSA-Brasil possuem baixa consciência corporal e não praticam atividade física em suficientemente. A alta prevalência de sobrepeso e obesidade observada pode ter contribuído para a baixa percepção corporal. A insatisfação e inacurácia parecem se associar com comportamentos relacionados à saúde de forma negativa, como inatividade física, consumo de álcool e compulsão alimentar. Porém, é possível afirmar que a imagem corporal parece não se relacionar de forma tão robusta com os fatores incluídos nesse estudo, mas ela pode ser considerada um indicador de comportamentos não saudáveis e revelar a necessidade de mudanças no estilo de vida. É importante que os indivíduos tenham capacidade de distinguir entre o ideal de corpo preconizado pela mídia e o corpo que faz bem, que expressa uma vida saudável. Dessa forma, a percepção da imagem corporal pode contribuir para promover mudanças positivas nos hábitos de vida e outras medidas de controle de peso apropriadas e benéficas para a saúde e bem-estar.

Introduction:Body image has been increasingly discussed in the scientific community because of its relation to obesity and its impact to influence individuals to adopt a healthy lifestyle. There is evidence that satisfaction with body image may be related to habits such as physical activity, as well as the perception of body image may be related to several factors not yet well defined.Objectives:This thesis has two objectives, namely: 1) verify whether the dissatisfaction with body image and nutritional status, indicated by body mass index and the waist / height ratio, are independently associated with the intensity of physical activity and whether this association differs between men and women; 2)investigate and describe which factors may be related to the misperception of weight status among adults.Methodology:The sample of this study is from the baseline of the Brazilian Longitudinal Study of Adult Health, comprised of 15,105 adults and elderly, government employees from universities and research centers located in six Brazilian states: Minas Gerais, São Paulo, Rio de Janeiro, Espírito Santo, Bahia and Rio Grande do Sul. Two articles were developed, each referring to one of the goals. In the first article, the response variable was the level of physical activity, categorized into three intensities. In an adult population (35-64 years), by means of logistic regression, weestimated the chance to practice physical activity in the presence of the variables satisfaction with body image, body mass index and the waist / height ratio. In the second article, by means oflogistic regression, it was investigatedwhich sociodemographic, behavioral, anthropometric and psychological factors were related to the misperception of weight status in adulthoodaccording to sex(35-64 years).Results:In the first article, the body image dissatisfaction was present even among normal weight individuals of both sexes and was associated with lesser chances of practicing moderate physical activity in women and intense physical activity in men. Men and women with central obesity were lessprone to practice physical activity of high or moderate intensity. Overweight and obese men were more likely to report vigorous physical activity while obese women were less likely to report this level of physical activity. The second article presented that, in both sexes, older age, former smoking and binge eating were associated with greater chances of overestimating the weight, while higher educational level was related to less chances of underestimate their weight. Among men, the chances of underestimating the weight were also higher in non-manual/routine occupations and those with depression; and lower in heavy drinkers. In women, lower schooling was associated to greater chances of underestimation, but with no consistent gradient.Conclusions:Our results reveal that the participants from the multicenter study ELSA-Brazil have low body awareness and do not exercise sufficiently. The high prevalence of overweight and obesity observed may have contributed to the low body perception. Body image dissatisfaction and misperception of weight status seem to be associated with behaviors related to health in a negative way, such as physical inactivity, alcohol consumption and binge eating. However, it is clear that the body image does not seem to relate as robustly with the factors included in the study, but it can be considered an indicator of unhealthy behaviors and highlight the need for changes in lifestyle. It is important that individuals are able to distinguish between the ideal body advocated by the media and the healthy body. Thus, the accurate perception of body image can help promote positive changes in lifestyle and other appropriate weight control measures and beneficial to health and well-being.

Fatores associados à subestimação materna do peso da criança: um estudo de base populacional / Factors associated with maternal underestimation of child's weight: a population-based study

Objetivo Investigar os fatores associados à subestimação materna do peso de crianças menores de cinco anos de Goiânia, Goiás. Métodos Estudo transversal, de base populacional, domiciliar, com 673 crianças menores de cinco anos de idade. A percepção materna do peso da criança foi obtida pela pergunta: "Atualmente, o que a senhora (mãe) acha do peso do seu filho?", e o estado nutricional da criança foi avaliado pelo índice de massa corporal por idade. Regressão múltipla de Poisson foi realizada a um nível de significância de 5%. Para a análise de concordância, foi utilizado o teste Kappa. Resultados Das crianças estudadas, 1,6% estavam magras, 87,7% eutróficas e 10,7% com excesso de peso. A maioria das mães (66,0%) identificou corretamente o peso de seus filhos; 5,2% superestimaram, e 28,8% subestimaram. Mães de crianças com excesso de peso, idade superior a 24 meses, apresentaram maior prevalência de subestimação, enquanto as mães com excesso de peso e maior escolaridade apresentaram menor subestimação do peso das crianças. A concordância entre a opinião materna sobre o peso da criança e o real estado nutricional da criança foi de 0,12 (p<0,001). CONCLUSÃO Existe uma distorção na percepção materna do peso de crianças menores de cinco anos. A subestimação materna do peso da criança apresentou associação direta com idade e estado nutricional da criança e associação inversa com escolaridade e estado nutricional materno. Sugere-se atenção no atendimento a essas mães com o objetivo de evitar o ganho de peso excessivo nessa idade e prejuízos na saúde da criança. .

Objective To investigate the factors associated with maternal underestimation of weight status of children under five years in Goiânia, Goiás, Brazil. Methods A population-based cross-sectional study involving 673 children under five years of age was carried out. Maternal perception of child's weight was assessed by the question: "What do you think about your child's current weight?". The child's nutritional status was determined in terms of body mass index-for age. Poisson regression was used at 5% significance level. Concordance analysis was performed using the Kappa test. Results Among the children studied, 1.6 % were lean, 87.7% eutrophic, and 10.7% overweight. Most mothers (66.0%) correctly classified the weight of their children, 5.2% overestimated it, and 28.8% underestimated it. Mothers of overweight children and those whose children were older than 24 months had a higher prevalence of underestimation of weight, whereas the overweight mothers and those with higher education level had a lower prevalence of underestimation of weight of their children. The correlation between maternal perception of the chil's weight and the actual child's nutritional status was 0.12 (p<0.001). Conclusion Maternal misperception of weight of children under five years was observed. Maternal underestimation of their child's weight was directly associated with age and nutritional status of the child, and it was inversely associated with maternal education level and nutritional status. More attention should be paid to these mothers in order to prevent excessive weight gain at this age and further harm to children's health. .

Association between Actual or Perceptional Weight Status and Mental Health Issues in Adolescents in Korea

BACKGROUND: Mental health issues in adolescents have recently emerged as a social concern. Previous studies reported that there was a relationship between body image perception and mental health. The purpose of this study was to determine the correlations between actual or perceptional weight status and mental health issues in adolescents in Korea. METHODS: Data was based on the 5th National Health and Nutrition Examination Survey Data (2010-2012). The subjects were 1989 adolescents aged 12 to 18 years. Depending on the actual or perceptional weight status, participants were divided into several groups. Mental health indicators included experiencing stress, depressed mood and suicidal ideation. RESULTS: The multiple logistic regression analysis was conducted controlling for age, abdominal obesity, smoking and alcohol use, potency of exercises, and household income. Although this study did not find a correlation between actual weight status and mental health variables, it did find that girls who perceived themselves as overweight were more likely to experience stress (odds ratio, 2.24; 95% CI, 1.41-3.56) and depressed mood (odds ratio, 1.91; 95% CI, 1.01-3.62). CONCLUSIONS: Adolescent females in Korea who perceived themselves as overweight experienced significantly more stress and depressed mood.
