RESUMO

A síndrome metabólica é caracterizada pela presença concomitante de alteração na glicemia, dislipidemia, elevação da pressão arterial e adiposidade excessiva, os quais elevam o risco cardiovascular. O objetivo deste trabalho foi analisar os parâmetros da síndrome metabólica e a associação com o consumo de alimentos ultraprocessados e bebidas adoçadas em adolescentes com excesso de peso. Realizou-se um estudo transversal, conduzido com 67 adolescentes com excesso de peso, de um ambulatório pediátrico de um hospital público no município de São Paulo. A avaliação antropométrica consistiu na aferição de peso, estatura e circunferência da cintura. Foram coletados dados de glicose, triglicérides, HDL-c, e pressão arterial, e a síndrome metabólica (SM) analisada de acordo com critérios da Associação Brasileira de Nutrologia. O consumo alimentar foi avaliado pelo questionário de frequência alimentar semiquantitativo. A prevalência de síndrome metabólica foi de 56,7%. Os parâmetros mais prevalentes foram redução de HDL-c (71,6%), elevação da pressão arterial sistólica (70,1%) e da glicemia de jejum (64,2%). Observou-se correlação positiva entre a glicemia de jejum e o consumo de alimentos ultra processados e bebidas adoçadas.

Metabolic syndrome is characterized by the concomitant presence of changes in blood glucose, dyslipidemia, elevated blood pressure and excessive adiposity, which increase cardiovascular risk. The objective of this study was to analyze the parameters of metabolic syndrome and the association with the consumption of ultra-processed foods and sweetened beverages in overweight adolescents. A cross-sectional study was carried out with 67 overweight adolescents from a pediatric outpatient clinic of a public hospital in the city of São Paulo. The anthropometric assessment consisted of measuring weight, height and waist circumference. Data on glucose, triglycerides, HDL-c, and blood pressure were collected, and metabolic syndrome (MS) was analyzed according to criteria from the Brazilian Association of Nutrology. Food consumption was assessed using the semi-quantitative food frequency questionnaire. The prevalence of metabolic syndrome was 56.7%. The most prevalent parameters were a reduction in HDL-c (71.6%), and an increase in systolic blood pressure (70.1%) and fasting blood glucose (64.2%). Blood glucose was positively associated with the sweetened beverage consumption score and BMI. It is concluded that there is a high prevalence of metabolic syndrome in adolescents, with glycemia being associated with the consumption of sweetened beverages.

RESUMO

Obesity is associated with inflammation and an increased risk of cardiovascular disease and premature mortality, as well as a range of other conditions. Obesity is a growing global problem, not only in adults, but also in children and adolescents. Therefore, the present study aimed to assess the effects of a one-year interdisciplinary intervention on the cardiometabolic and inflammatory profiles of adolescents with obesity. Twenty-two adolescents completed the intervention, which included clinical, nutritional, psychological and physical exercise counselling. Body composition, and metabolic, inflammatory, and cardiovascular risk biomarkers were analyzed before and after one year of intervention. Visceral and subcutaneous fat were determined ultrasonographically. The homeostasis model assessment of insulin resistance (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI) equation were used to estimate insulin resistance and insulin sensitivity, respectively. A reduction in body mass, adiposity, glucose, and insulin and an improved lipid profile were observed after the therapy. Hyperleptinemia was reduced from 77.3% to 36.4%. Plasminogen activator inhibitor-1 (PAI-1), intercellular adhesion molecule 1 (ICAM-1), leptin, the leptin/adiponectin ratio, and the adiponectin/leptin ratio were also significantly improved. Metabolic changes were associated with a reduction in visceral fat and waist circumference, and adiponectin and the leptin/adiponectin ratio were associated with HOMA-IR. The interdisciplinary therapy promoted improvements in hyperleptinemia and metabolic, inflammatory, and cardiovascular biomarkers.

RESUMO

Understanding infant diet is of great importance to elucidate its determining factors. It is known that parents exert great influence on the formation of their children's eating behavior and are able to define their children's eating patterns at other moments in their future life cycles. However, the effects of parental practices and perceptions on the food consumption and nutritional status of their children need to be elucidated more clearly. This study aimed to verify the association of parental practices and perceptions with food consumption and nutritional status of children. This is a cross-sectional study, conducted with parents and children aged two to six years old. Questionnaires were applied using the Google Forms® platform to investigate parental practices and perceptions, sociodemographic data, weight and height, child food consumption, and family food routine. The instruments used in data collection were the Child Feeding Questionnaire, the Child Feeding Frequency Questionnaire, and the authors' own questions. For statistical analysis, p<0.05 was considered significant. Sixty-eight parents of children were interviewed, of which 89.7% were mothers and 72.1% worked outside the home. Among children, 54.4% were male and 60.3% eutrophic. Among those parents who worked outside the home, preschoolers had most of their meals at school. There was an association between the parents' perception of the child's weight and nutritional status, frequency of parental responsibility in deciding the right type of food with the child's nutritional status, and parents' education. Controlling the intake of sweets was associated with parental age. Snack consumption by children was associated with parental education. It was concluded that parental practices and perceptions were associated with the nutritional status of preschoolers, but there was no association with food consumption.

Trata-se de um estudo transversal, conduzido com pais e crianças de dois a seis anos. Aplicou-se questionários pela plataforma Google Forms®, para investigar as práticas e percepções parentais, dados sociodemográficos, peso e estatura, consumo alimentar infantil e rotina alimentar da família. Os instrumentos utilizados na coleta de dados foram o Questionário de Alimentação da Criança, Questionário de Frequência Alimentar da Criança e questões de autoria própria. Para análise estatística considerou-se significativo p<0,05. Foram entrevistados 68 pais de crianças, sendo que 89,7% eram mães e 72,1% trabalhavam fora de casa. Entre as crianças, 54,4% eram do sexo masculino e 60,3% eutróficos. Dentre aqueles pais que trabalhavam fora de casa, os pré-escolares realizavam a maior parte das refeições na escola. Verificou-se associação entre a percepção dos pais sobre o peso da criança e estado nutricional; frequência da responsabilidade dos pais em decidir o tipo correto de comida com o estado nutricional infantil e com a escolaridade dos pais. O controle da ingestão de doces associou-se à idade dos pais. O consumo de lanches pelas crianças associou-se a escolaridade dos pais. Concluiu-se que as práticas e percepções parentais foram associadas ao estado nutricional de pré-escolares, porém não houve associação com o consumo alimentar.

RESUMO

A insatisfação com a imagem corporal é um importante fator relacionado à transtornos alimentares. Nota-se que as redes sociais divulgam continuamente o corpo magro e musculoso, o que contribuiu para a internalização do corpo ideal. Entretanto, precisa ser melhor esclarecida a influência das redes sociais sobre a insatisfação com a imagem corporal em universitários da saúde. O objetivo deste estudo foi investigar a relação entre a insatisfação com a imagem corporal e o uso de redes sociais em estudantes de graduação da área da saúde. Realizou-se pesquisa transversal, com coleta de dados online pela plataforma Google Forms®. A amostra foi composta por 203 estudantes da área da saúde, na faixa etária entre 18 e 40 anos. Aplicou-se o questionário Body Shape Questionnaire (BSQ) para avaliar a insatisfação com a imagem corporal. A influência das redes sociais sobre estilo de vida e foi investigada pelo escore gerado pela somatória de seis questões, com respostas em escala Likert. Foram coletadas informações socioeconômicas, peso e altura autoreferidos. A análise estatística foi realizada pelo software JAMOVI, considerando-se o nível de significância p≤0,05. O escore de insatisfação com a imagem corporal foi significativamente superior nas mulheres, de maneira que se verificou que 65,4% delas apresentam algum grau de insatisfação. O IMC, número de redes sociais acessadas e o escore total de influência da mídia associaram-se positivamente à insatisfação com a imagem corporal. Conclui-se que a insatisfação com a imagem corporal se associou ao IMC, número de redes sociais e escore de influência das redes sociais, sendo observado principalmente em mulheres.

Dissatisfaction with body image is an essential factor related to eating disorders. It is noted that social networks continually publicize the lean and muscular body types, which have contributed to the internalization of the ideal body. However, social networks' influence on body image dissatisfaction in health university students must be clarified. This study aimed to investigate the relationship between dissatisfaction with body image and the use of social networks among undergraduate healthcare students. A cross-sectional survey was conducted, with online data collection using the Google Forms® platform. The sample consisted of 203 healthcare course students aged between 18 and 40 years. The Body Shape Questionnaire (BSQ) was applied to assess body image dissatisfaction. The influence of social networks on lifestyle was investigated by the score generated by the sum of six questions, with answers on a Likert scale. Socioeconomic information and selfreported weight and height were collected. Statistical analysis was performed using the JAMOVI software, considering a significance level of p≤0.05. The body image dissatisfaction score was significantly higher in women, and 65.4% had some degree of dissatisfaction. BMI, number of social networks accessed, and the overall media influence score were positively associated with dissatisfaction with body image. It is concluded that dissatisfaction with body image was associated with BMI, number of social networks, and social network influence score and was observed mainly in women.

RESUMO

Depression and obesity are highly prevalent and are considered inflammatory pathologies; in addition, they are also associated with dietary patterns including types of fatty acids (FA). Changes in the FA composition in the brain are determined by changes in the content and quality of dietary and serum FA. The aim of this study was to verify the relationships between serum-free FA, inflammatory processes and depressive symptoms in obese adolescents. This was a cross-sectional study that analysed a database composed of 138 post-pubertal adolescents. Data regarding the depressive symptoms, body composition, glucose metabolism, lipid profile, FA profile, leptin concentration, as well as adiponectin, IL-A, IL-6, IL-10, TNF-α, C-reactive protein and plasminogen activator inhibitor-1 levels of the subjects were collected. A total of 54·6 % of the adolescents presented with depressive symptoms, and there were positive correlations between depressive symptoms and serum saturated fatty acids (SFA) content, body fat, and inflammatory adipokines, such as leptin, IL-6, and the leptin/adiponectin ratio. Moreover, the content of n-3 polyunsaturated fatty acids (PUFA) was negatively correlated with depressive symptoms, suggesting that eicosatrienoic acid (C20:2n6) and dihomo-γ-linolenic acid (C20:3n-6) are independently associated with depressive symptom scores and can be critical predictors of poor mental health in humans. These results point to the relationship between SFA and depressive symptoms in obese adolescents. However, longitudinal studies are needed to confirm the causality between dietary SFA and depression in obese individuals.

RESUMO

ABSTRACT: Objective: To investigate the association between parental feeding practices and the consumption of ultra-processed foods in preschool children. Methods: Cross-sectional study with 140 parents (father and mother) and their children (2-6 year-old). Parental feeding practices were assessed using the Comprehensive Feeding Practices Questionnaire. Children's body weight and height were measured, and body mass index z-score per age was calculated. Parental anthropometric measurements (body weight and height) were obtained by self-report, and body mass index was calculated. The consumption of ultra-processed foods was assessed through the Child Food Frequency Questionnaire and the daily intake score was calculated. Multivariable linear regression analyses were performed to investigate the association between parental feeding practices and the consumption of ultra-processed foods. Results: Children's ultra-processed food consumption was negatively associated with the "Monitoring" parental feeding practices. On the other hand, "Emotion Regulation" and "Health restriction" parental feeding practices were positively associated with the ultra-processed food consumption score. Conclusion: Ultra-processed food consumption was associated to the "Monitoring", "Emotion regulation" and "Health restriction" parental feeding practices in preschool children. These results support the importance of using successful parental feeding practices to promote healthy eating in preschoolers.

RESUMO: Objetivo: O estudo buscou investigar a associação entre as práticas alimentares parentais e o consumo de alimentos ultraprocessados em crianças pré-escolares. Métodos: Estudo transversal realizado com 140 pares de pais e crianças de 2 a 6 anos de idade. As práticas parentais foram avaliadas pelo questionário Comprehensive Feeding Practices Questionnaire. O peso e a estatura das crianças foram aferidos e o escore z de índice de massa corporal para idade, calculado. A avaliação antropométrica dos pais foi realizada por meio do autorrelato de peso e altura e cálculo do índice de massa corporal. O consumo de alimentos ultraprocessados foi avaliado pelo Questionário de Frequência Alimentar da Criança e pelo cálculo de escore de consumo diário. Realizaram-se análises de regressão linear múltipla para avaliar a associação entre as práticas alimentares parentais e o consumo de alimentos ultraprocessados. Resultados: O consumo de alimentos ultraprocessados pelas crianças associou-se negativamente à prática parental de "Monitoramento". Por outro lado, as práticas alimentares parentais de "Regulação da emoção" e "Restrição para saúde" associaram-se positivamente ao escore de consumo de alimentos ultraprocessados. Conclusão: Conclui-se que o consumo de alimentos ultraprocessados por crianças pré-escolares relacionou-se às práticas alimentares parentais de "Monitoramento", "Regulação da emoção" e "Restrição para saúde". Esses resultados ressaltam a importância do uso de práticas alimentares parentais com desfecho positivo para a promoção de uma alimentação saudável em pré-escolares.

RESUMO

BACKGROUND: The purpose of the present study was to compare the impact of semi-intensive and intensive interdisciplinary weight-loss therapies on the treatment of metabolic syndrome (MS) and selected inflammatory markers in adolescents with obesity. METHODS: The study included 166 adolescents enrolled in two groups for 22 weeks: the intensive group (in-person aerobic and resistance exercise three times a week, and psychological and nutritional counselling once a week), or the semi-intensive group (six in-person exercise orientation meetings and six in-person psychological support sessions with an online nutritional and exercise program). Anthropometric parameters, blood pressure, fasting glucose, insulin, lipid profile, triglycerides (TG), leptin and adiponectin were assessed before and after the interventions. RESULTS: Body weight and waist circumference decreased in both groups (P<0.001) and large effect sizes (η2= 0.586 and η2=0.465, respectively) were noted. Significant time and group interactions were found (P=0.001) with medium effect sizes (η2=0.095 and η2=0.105, respectively). The prevalence of MS decreased from 27.9% to 13.1% (P=0.012) and 29.4% to 5.9% (P=0.004) in the semi-intensive and intensive groups, respectively. All MS risk factors decreased significantly over time (P<0.001) and a significant time*group interaction was observed (P<0.05), except for fasting TG (P=0.832) and glucose (P=0.128, η2=0.021). CONCLUSION: The results suggested that both approaches promoted significant clinical improvement in the condition of adolescents with MS and reduced associated risk factors. Studies that consider the cost effectiveness of both treatments are still needed to determine whether semi-intensive care, with its lower financial costs, may be a suitable option to treat obesity and MS in adolescents with obesity.

RESUMO

ABSTRACT Objective: To investigate the effects of an interdisciplinary intervention on biomarkers of inflammation and their relationship with fibroblast growth factor 21 (FGF21) concentrations in women with overweight and obesity. Subjects and methods: Thirty-one women were enrolled in a 12-week interdisciplinary weight loss program delivered by a team comprising an endocrinologist, nutritionist and exercise physiologist. Body composition; anthropometric measures; metabolic and inflammatory markers including adiponectin, leptin, and atrial natriuretic peptide (ANP) were assessed at baseline and post-therapy. The homeostasis model assessment of insulin resistance (HOMA-IR) and the homeostasis model assessment of adiponectin (HOMA-AD) were calculated. The participants were divided into two groups: those with increased FGF21, and those with decreased FGF21. Results: The sample comprised women aged 32 ± 5 years with a body mass index of 33.64 ± 3.49 kg/m2. Body weight, waist circumference and leptin concentration were decreased in the whole sample after therapy. However, only the group with an increase in FGF21 concentration presented significant improvements in adiponectin concentration and adiponectin/leptin ratio. Moreover, although there was a reduction of leptin in both groups, it was greater in the increased FGF21 groups. There was a reduction in ANP in the decreased FGF21 group. Conclusions: Changes in FGF21 concentrations were different among the women participating in the weight loss program, with some having increased levels and some reduced levels. Furthermore, improvements in adiponectin and the adiponectin/leptin ratio were found only in the group with increased FGF21 concentration.
