Analysis of scientific production aligned with the Food and Nutrition Security Strategy of Portuguese-Speaking African Institutions: a systematic scoping review / Análise da produção científica alinhada com a Estratégia de Segurança Alimentar e Nutricional das Instituições Africanas de Língua Portuguesa: uma revisão sistemática de escopo

ABSTRACT This systematic scoping review aimed to map and characterize the scientific production of researchers from Portuguese-speaking African institutions that align with the Food and Nutrition Security Strategy of the Community of Portuguese-Speaking Countries. The literature search was conducted using six electronic databases (PubMed, EMBASE, Virtual Health Library, Scientific Electronic Library Online, Scopus, and Web of Science), with no restrictions on the year of publication nor language. Through the search strategy, 10,061 records were identified, of which 502 documents and 654 researchers were selected by Food and Nutrition Security specialists along three axes: 1) Policy governance; 2) Access to food; 3) Availability of food. Institutional researchers from Mozambique (66.9%), Guinea-Bissau (15.9%), and Angola (11.4%) presented the most publications and international collaborations. Researchers from Cape Verde, Sao Tome and Principe, and Equatorial Guinea institutions added only 5.8% of the total production. A greater number of publications (61%) was related to axis two of the Food and Nutrition Security Strategy of the Community of Portuguese-Speaking Countries. The most studied themes were sustainable development, child malnutrition, and agricultural production for the first, second, and third axis, respectively. In general, scientific publications have shown limitations in their approaches due to the challenge imposed by the complexity of the food system. However, there has been a quantitative evolution in publications in the last decade, with a greater participation of researchers from Portuguese-speaking African institutions.

RESUMO Esta revisão sistemática de escopo teve como objetivo mapear e caracterizar a produção científica de pesquisadores de instituições africanas de língua portuguesa que se alinham com a Estratégia de Segurança Alimentar e Nutricional da Comunidade dos Países de Língua Portuguesa. A busca das literaturas foi realizada em seis bases de dados eletrônicas (PubMed, EMBASE, Biblioteca Virtual em Saúde, Scientific Electronic Library Online, Scopus e Web of Science), sem restrição quanto ao ano de publicação e ao idioma. Por meio da estratégia de busca, foram identificados 10.061 registros, dos quais 502 documentos e 654 pesquisadores foram selecionados por especialistas em Segurança Alimentar e Nutricional em três eixos: 1) Governança de políticas; 2) Acesso à alimentação; 3) Disponibilidade de alimentos. Pesquisadores de intuições de Moçambique (66,9%), Guiné-Bissau (15,9%) e Angola (11,4%) foram os que apresentaram o maior número de publicações e colaborações internacionais. No entanto, os pesquisadores das instituições de Cabo Verde, São Tomé e Príncipe e Guiné Equatorial somaram apenas 5,8% da produção total. Foi observado maior número de publicações (61%) relacionadas com o eixo dois da Estratégia de Segurança Alimentar e Nutricional da Comunidade dos Países de Língua Portuguesa. As temáticas mais estudadas foram desenvolvimento sustentável, desnutrição infantil e produção agrícola para o primeiro, segundo e terceiro eixo, respectivamente. De forma geral, as publicações científicas mostraram limitações em suas abordagens frente ao desafio imposto pela complexidade do sistema alimentar. Todavia, foi houve uma evolução quantitativa nas publicações na última década; além disso, maior participação de pesquisadores de instituições africanas de língua portuguesa pode ser vislumbrada.

Ambiente alimentar e excesso de peso em escolares: uma revisão sistemática sul-americana

[RESUMO]. Objetivo. Identificar e compilar os achados de estudos observacionais que analisaram a relação de fatores do ambiente alimentar escolar e individuais de consumo na escola com excesso de peso em escolares da América do Sul no período de 2011 a 2021. Métodos. A pesquisa foi realizada em cinco bases de dados (PubMed, Web of Science, SciELO, Scopus e LILACS) e no Google Scholar, além de consulta a especialistas. Foram selecionados estudos observacionais com escolares de 5 a 19 anos, realizados na América do Sul, que usaram medidas objetivas para avaliar excesso de peso, como o índice de massa corporal (Organização Mundial da Saúde e/ou International Obe- sity Task Force), em associação a fatores do ambiente alimentar escolar e individuais de consumo na escola. O protocolo foi registrado na plataforma PROSPERO (CRD42020212383). Resultados. Dos 906 registros identificados, 13 estudos transversais (um da Argentina, um do Equador e 11 do Brasil) foram incluídos na revisão. As prevalências variaram de 7,5% a 32,5% para sobrepeso e 1,7% a 28,0% para obesidade. Fatores do ambiente alimentar escolar, dos domínios político e físico (como educação alimentar e nutricional insatisfatória e indisponibilidade de refeições preparadas na escola) se associaram com maiores prevalências de excesso de peso. Fatores individuais relacionados à adesão ao programa de alimentação escolar (como consumo da alimentação oferecida pela escola ao invés de lanche trazido de casa) se associaram a menores prevalências de excesso de peso. Conclusões. São escassos os estudos sul-americanos enfocando a associação entre fatores do ambiente alimentar escolar e/ou individuais e excesso de peso em escolares. As evidências restritas a contextos locais ou regionais incentivam novos estudos de abrangência nacional.

[ABSTRACT]. Objective. To identify and compile the findings of observational studies analyzing the relationship of factors from the school food environment and individual factors related to food consumption in school with excess weight in schoolchildren from South America in the period from 2011 to 2021. Method. The literature review involved a search performed in five databases (PubMed, Web of Science, SciELO, Scopus, and LILACS) and in Google Scholar, as well as a consultation with specialists. Studies were selected if they had an observational design, included schoolchildren aged 5 to 19 years, were performed in South America, and used objective measures such as body mass index (World Health Organization and/ or International Obesity Task Force) to assess weight in association with school food environment factors and individual school consumption factors. The protocol was registered in PROSPERO (CRD42020212383). Results. Of 906 identified records, 13 cross-sectional studies (one from Argentina, one from Ecuador, and 11 from Brazil) were included in the review. The prevalence of overweight ranged from 7.5% to 32.5%, and of obesity, from 1.7% to 28.0%. School environment factors from the policy and physical domains (such as unsatisfactory food and nutrition education and unavailability of school-prepared meals) were associated with increased prevalence of excess weight. Individual factors related to adherence to the school meal program (such as consumption of meals offered by the school instead of bringing a snack from home) were associated with lower prevalence of excess weight. Conclusions. Only a few studies are available in South America with a focus on individual and/or school food environment factors and excess weight in schoolchildren. Since the available evidence is restricted to local or regional contexts, new national-level studies are warranted.

[RESUMEN]. Objetivo. Identificar y recopilar los resultados de estudios observacionales realizados en América del Sur, en los cuales se analizó la relación entre los factores del ambiente alimentario escolar y los factores individuales de consumo de la población escolar con exceso de peso en el período del 2011 al 2021. Métodos. La investigación se realizó en cinco bases de datos (PubMed, Web of Science, SciELO, Scopus y LILACS), en Google Scholar y mediante consulta a expertos. Se seleccionaron estudios observacionales realizados en América del Sur con escolares de 5 a 19 años, en los cuales se emplearon medidas objetivas para evaluar el exceso de peso como el índice de masa corporal (Organización Mundial de la Salud y Inter- national Obesity Task Force) en relación con factores del ambiente alimentario escolar y factores individuales de consumo en la escuela. El protocolo se registró en la plataforma PROSPERO (CRD42020212383). Resultados. De los 906 registros identificados, en la revisión se incluyeron 13 estudios transversales (uno de Argentina, uno de Ecuador y 11 de Brasil). Las tasas de prevalencia del sobrepeso fluctuaron entre 7,5% y 32,5% y las de la obesidad, entre 1,7% y 28,0%. Los factores del ambiente alimentario escolar de los dominios político y físico (como educación poco satisfactoria en cuanto a alimentos y nutrición, y la falta de comidas preparadas en la escuela) guardaron relación con mayores tasas de prevalencia del exceso de peso. Los factores individuales referentes a la adhesión al programa de alimentación escolar (como el consumo de la alimentación ofrecida por la escuela en vez de la merienda llevada de la casa) guardaron relación con meno- res tasas de prevalencia del exceso de peso. Conclusiones. Son escasos los estudios realizados en América del Sur sobre la relación entre los factores del ambiente alimentario escolar y los factores individuales y el exceso de peso de la población escolar. El hecho de que la evidencia se limite a los contextos locales o regionales crea un incentivo para realizar nuevos estudios de alcance nacional.

Genetic polymorphisms are not associated with energy intake 1 year after Roux-en-Y gastric bypass in women.

BACKGROUND: The present study aimed to investigate the influence of food intake on body weight loss (WL) and the association of gene polymorphisms, 1 year after Roux-en-Y gastric bypass (RYGB) surgery. METHODS: In total, 95 obese women (age ranged 20-50 years) in a Brazilian cohort underwent RYGB surgery and completed the study. Anthropometric measurements and food intake were assessed before and 1 year after surgery. Twelve gene polymorphisms (GHRL rs26802; GHSR rs572169; LEP rs7799039; LEPR rs1137101; 5-HT2C rs3813929; UCP2 rs659366; UCP2 rs660339; UCP3 rs1800849; SH2B1 rs7498665; TAS1R2 rs35874116; TAS1R2 rs9701796; and FTO rs9939609) were determined using a real-time polymerase chain reaction and a TaqMan assay. The subjects were divided into quartiles regarding percentage of excess weight loss (%EWL). The effect of genetic variants on energy and macronutrient intake was evaluated by simple logistic regression, followed by multiple logistic regression. RESULTS: Subjects in the first and second quartiles showed a higher initial body mass index. Energy and macronutrient intake before and 1 year after RYGB surgery did not differ between the %EWL quartiles. None of gene polymorphisms investigated showed an association with the estimated energy intake 1 year after surgery. CONCLUSIONS: In conclusion, the estimate energy and food intake did not predict a greater body WL 1 year after RYGB surgery. In addition, the 12 gene polymorphism investigated did not affect the energy intake among female patients.

Perceptions of patients in the waiting line for bariatric surgery: contributions from the experience of an educational process / Percepções de pacientes na fila de espera para cirurgia bariátrica: contribuições a partir da experiência de um processo educativo / Percepciones de pacientes en la fila de espera para cirugía bariátrica: contribuciones a partir de la experiencia de un proceso educativo

The present study is a qualitative research with the objective of analyzing the perceptions of patients in the face of the challenges in the bariatric surgery line through focal groups. All patients were treated with an outpatient protocol, however, they were divided into two groups, one participated in the educational process and the other did not. Four categories of analysis were drawn up and discussed in the light of the current literature. Patients from the educational process were able to express themselves with greater positivity in view of the challenges and they showed better resources for going through the emotional suffering, the worsening of comorbidities and the risk of death. The results show the potential of education in health and of group work in the promotion of self-care and well-being.(AU)

O presente estudo trata-se de uma pesquisa qualitativa com o objetivo de analisar as percepções dos pacientes diante dos desafios na fila da cirurgia bariátrica por meio de grupos focais. Todos os pacientes foram atendidos com protocolo ambulatorial, porém, foram divididos em dois grupos, um participou do processo educativo e o outro não. Quatro categorias de análise foram elaboradas e discutidas à luz da literatura atual. Os pacientes do processo educativo conseguiram se expressar com maior positividade diante dos desafios e apresentaram melhores recursos para atravessar o sofrimento emocional, o agravamento das comorbidades e o risco de morte. Os resultados mostram o potencial da educação em saúde e do trabalho em grupo na promoção do autocuidado e do bem-estar.(AU)

A nutritionist approach to psychiatric treatment: Notes from a brief experience

ABSTRACT Objective: This study aims to describe the work of the nutritionist in a psychiatric outpatient clinic of a university hospital, with patients with excess weight due to the use of certain psychiatric medications. Method: Content analysis of the clinical history and brief field notes, as complementary material. The clinical-qualitative method was applied in data collection and analysis. Results: Conversations with patients focused on their relationship with food were more effective in managing excessive weight gain than insistence on individualized and restrictive diets. The role of the family was important to strengthen the bond and favor dietary changes. Efforts to identify the emotions involved in eating, including the pleasures given by emotional, cultural, and social factors were also important. Conclusions: Nutritional care in the psychiatric field should emphasize dialogue related to the eating practices of patients. Strict dietary prescriptions can have the same unproductive effect as traditional biomedical practices if they do not consider subjective aspects of patients.

RESUMEN Objetivo: El objetivo de este estudio fue describir el trabajo del nutricionista en una clínica ambulatoria de psiquiatría de un hospital universitario, en pacientes con exceso de peso debido al uso de ciertos medicamentos psiquiátricos. Método: Análisis del contenido de la historia clínica y de breves notas de campo, como material complementario. Se aplicó el método clínico-cualitativo en la recolección y análisis de los datos. Resultados: El autor principal de este artículo, una nutricionista, indica que las conversaciones con pacientes centradas en su relación con la comida fueron más efectivas para manejar el aumento de peso excesivo do que la insistencia en las dietas individualizadas y restrictivas. El rol de la familia fue importante para fortalecer el vínculo e favorecer los cambios alimentarios. También fueran importantes los esfuerzos para identificar las emociones involucradas en la alimentación, incluidas los placeres dados por factores emocionales, culturales y sociales. Conclusiones: La atención nutricional en el campo psiquiátrico debe enfatizar el diálogo relacionado con las prácticas alimentarias de los pacientes. Las prescripciones estrictamente dietéticas pueden tener el mismo efecto improductivo que las prácticas biomédicas tradicionales si tampoco toman en cuenta los aspectos subjetivos de los pacientes.

Oral condition of institutionalized older people: influence on anthropometric indicators, food and nutrient intake

ABSTRACT Objective: To assess whether there are differences between oral problems and food, energy, and nutrient intake and anthropometric indicators of institutionalized older adults. Methods: A total of 150 older people participated in the study. Their nutritional status was determined by anthropometric indicators and food intake. Oral problems were examined by a trained dentist who checked for caries, periodontitis, dry mouth, edentulism, and poorly-fitting partial or complete dentures. The categorical variables were analyzed by the Fisher's Exact Test and the continuous variables were analyzed by the Student's t-test for parametric data and the Mann-Whitney test for nonparametric data (p≤0.05). Results: Older people with oral problems presented lower anthropometric measurements and indices except for biceps skinfold thickness and consumed less energy (p= 0.027), protein (p= 0.012), lipids (0.012), and pan-fried meats (p= 0.001). Conclusion: Anthropometric indicators and the energy, protein and lipid intake were lower in elderly people with oral problems. This work warns about the importance of oral health for the good nutrition of older people and the need to establish strategies to adapt the diet of this population.

RESUMEN Objetivo: Evaluar si existe una diferencia entre los problemas orales y la ingesta de alimentos, energía y nutrientes e indicadores antropométricos de adultos mayores institucionalizados. Métodos: Un total de 150 personas mayores participaron en el estudio. Su estado nutricional se determinó mediante indicadores antropométricos y la ingesta de alimentos. Los problemas orales fueron examinados por un dentista capacitado que verificó la presencia de caries, periodontitis, boca seca, edentulismo y dentaduras postizas parciales o completas mal ajustadas. Las variables categóricas se evaluaron mediante la Prueba Exacta de Fisher y las variables continuas se evaluaron mediante la prueba t de Student para datos paramétricos y la prueba de Mann-Whitney para datos no paramétricos (p≤0.05). Resultados: Las personas mayores con problemas orales presentaron mediciones e índices antropométricos más bajos, excepto el grosor del pliegue cutáneo del bíceps y consumieron menos energía (p= 0.027), proteínas (p= 0.012), lípidos (0.012) y carnes fritas (p= 0.001). Conclusión: Los indicadores antropométricos y el consumo de energía, proteínas y lípidos fueron menores en personas mayores con problemas bucales. Este trabajo advierte sobre la importancia de la salud oral para la buena nutrición de las personas mayores y la necesidad de establecer estrategias para adaptar la dieta de esta población.

Nutritional therapy in hospital care of in-patients with Covid-19: evidence, consensus and practice guidelines / Terapia nutricional na atenção hospitalar de pacientes hospitalizados com Covid-19: evidências, consensos e guias de práticas

ABSTRACT Objective The objective of this work was to review papers that deal with nutritional therapy of inpatients with Covid-19 from the beginning of the pandemic. The survey covered the period until the month of September 2020. Methods This is a review of the indexed literature (Scopus, Pubmed and Lilacs), including area consensus. Results The review showed that the initial recommendations were based on generic assumptions and, as specific knowledge was being produced, the recommendations became more targeted. Conclusion In the health crisis generated by Covid-19, in the context of uncertainties related to nutritional care procedures, knowledge and action strategies were generated, coordinated by researchers and health professionals.

RESUMO Objetivo O objetivo deste trabalho foi revisar as publicações que trataram da terapia nutricional do paciente hospitalizado com Covid-19 desde o início da pandemia até o mês de setembro de 2020. Métodos Trata-se de uma revisão dos trabalhos indexados nas bases de dados Scopus, Pubmed e Lilacs, incluindo consensos da área. Resultados A revisão mostrou que as recomendações iniciais pautaram-se em pressupostos genéricos e, conforme o conhecimento específico foi sendo produzido, as recomendações passaram a ser mais direcionadas. Conclusão Na crise sanitária gerada pela Covid-19, no contexto de incertezas relacionadas aos procedimentos de atenção nutricional, foram gerados conhecimentos e estratégias de ação, coordenados por pesquisadores e profissionais de saúde.

Food practices and their meanings in the daily routine of a university / Práticas alimentares e seus significados no cotidiano de uma universidade

ABSTRACT Objective This study aimed at knowing and analyzing sociocultural meanings of the daily dietary practices revealed by a university community, in the context of a wellness program to their community and its surroundings. Methods The research team ran 28 workshops with the participation of 34 university units and 558 subjects in total. All workshops were recorded and transcribed verbatim. Content analysis was performed with the identification of emerging themes and categories. Results From the analysis of this material four categories emerged. There is the desire caused by the pleasure of having meals in a group of people and consuming foods rich in fat and sugar, but with its consumption shrouded by guilt. Healthy foods were considered important but related to obligation and displeasure. The community also wants to consume healthy foods daily in the academic environment, however, pointed out barriers such as an increasing pace of work and lack of time. Conclusion It was possible to identify barriers and desires related to food practices in the daily life of the university. This study demonstrated that changing the eating behavior of an academic community is a major challenge for wellness programs, even for an institution that produces and disseminates scientific knowledge.

RESUMO Objetivo Este trabalho teve como objetivo conhecer e analisar os significados socioculturais das práticas alimentares cotidianas revelados pela comunidade de uma universidade brasileira no contexto de um programa de bem estar para sua comunidade e entornos. Métodos Foram realizadas 28 oficinas com a participação de 34 unidades universitárias e 558 pessoas. Todas as oficinas tiveram seu áudio gravado e transcrito. Foi realizada análise de conteúdo com a identificação de temas e categorias emergentes. Resultados A partir da análise do material transcrito, emergiram os significados em quatro categorias. Há o desejo pelo prazer de realizar as refeições em grupo e consumir alimentos ricos em gordura e açúcar, mas envolto por culpa. Alimentos saudáveis foram considerados importantes, mas seu consumo foi relacionado à obrigação e desprazer. Contudo, a comunidade deseja consumi-los diariamente no ambiente acadêmico, mas aponta barreiras como o aumento do ritmo de trabalho e falta de tempo. Conclusão Foi possível identificar barreiras e desejos relacionados às práticas alimentares no cotidiano da universidade. Este estudo mostrou que transformar o comportamento alimentar de uma comunidade acadêmica é um grande desafio para os programas de bem-estar, mesmo para instituições que produzem e disseminam conhecimentos científicos.

Randomized controlled trial protocol: A quanti-quali approach for analyzing the results of an intervention on the waiting list for bariatric surgery / Protocolo de estudo controlado randomizado: abordagem quanti-quali para análise de resultados de uma intervenção em fila de espera para cirurgia bariátrica

ABSTRACT Objective This article aims to describe the protocol of a randomized clinical trial and the baseline results of the study of a one-year interdisciplinary intervention in users of the public health system in the bariatric surgery waiting list. Methods A randomized, single-blind clinical trial will be conducted including 88 participants recruited on an outpatient clinic of the public health system. Participants were randomized into the control group (n=44), receiving the usual treatment; and into the intervention group (n=44), participating in the educational intervention. Participants had their food intake, negative affectivity and physical inactivity/sedentary behavior assessed, as well as anthropometric and body composition measurements; their blood samples were collected; and also had different physical capacity tests. Results Of the 157 participants invited, 27 had severe functional limitations, one was under-age, and four declined the study due to associated diseases. Eighty-eight participants were randomized: 44 for the Control Group and 44 for the Intervention Group. When comparing the demographic and biochemical characteristics, there were no differences between groups except for serum glucose (GC=110.4±46.8mg/dL and GI93.1±16.9mg/dL, p=0.039). Conclusion This study protocol describes the methodology used in the study of educational intervention for the promotion of health care of patients on the waiting list for bariatric surgery. It shows that there is similarity between the baseline comparison groups. Registro Brasileiro de Ensaios Clínicos (Brazilian Clinical Trials Registry), RBR-775y3d.

Accuracy of total energy expenditure predictive equations after a massive weight loss induced by bariatric surgery.

BACKGROUND AND AIMS: Predictive equations remain the clinical tool of choice to estimate the energy expenditure, however, poor accuracy has been found when applied in patients with severe obesity. The aim of this study was to test the accuracy of the total energy expenditure (TEE) those obtained by predictive equations of resting energy expenditure (REE) times individual estimates of metabolic equivalents (MET), taking as reference the TEE measured by doubly labeled water (DLW), before, six and twelve months after bariatric surgery. SUBJECTS AND METHODS: Twenty class III obese women (age: 29.4 ± 5.1 years; BMI: 44.9 ± 2.5 kg/m2), approved for Roux-en-Y gastric bypass participated in this study. TEE and body composition was measured after administration of a fixed dose of DLW. Predictive equations of REE were selected: Dietary Reference Intake (DRI), World Health Organization, Oxford, Harris-Benedict, Mifflin, De Lorenzo, Lazzer and Muller and their collaborators. The MET values were obtained individually by triaxial accelerometer. RESULTS: The patients showed 65% of excess weight loss. The body fat mass decreased 17% after 1 year of surgery. TEE (2930 ± 525 kcal.day-1) decreased by 20% (p < 0.05) by the sixth postoperative month (2319 ± 430 kcal.day-1), increasing 10% by the twelfth month (2538 ± 336 kcal.day-1). The Harris and Benedict (accuracy: 65%) and DRI equations (accuracy: 60%) yielded better results in the prediction of TEE values at pre-surgery. In the sixth month after surgery, only the equation of Harris and Benedict kept accuracy above 50%. At twelve months post-surgery, only the equation of Lazzer et al. considering body composition showed better prediction (accuracy: 50%) in this period. CONCLUSION: None of the prediction equations tested was accurate for estimating TEE for the 3 periods evaluated; however, while there are no reports of specific equations for class III obese women, the Harris and Benedict x MET and DRI equations, can describe the TEE with acceptable accuracy. After surgery, the best equation to be used will depend if the patient has been treated for weight loss and in which post-treatment period it is used.

The under-reporting of energy intake influences the dietary pattern reported by obese women in the waiting list for bariatric surgery / A subnotificação do consumo energético influencia os resultados de padrão alimentar relatado por mulheres obesas na fila de espera para cirurgia bariátrica

ABSTRACT Objective To verify the interference of the energy intake under-reporting in the determination of the dietary patterns and nutrient intakes reported by obese women in the waiting list for bariatric surgery. Methods The study included 412 women aged 20 to 45 years with a body mass index ranging from 35 to 60kg/m2 who were on waiting list for bariatric surgery. Data from three reported food intake and physical activity, body weight, and height were used for estimating the reported energy intake, physical activity level, and resting energy expenditure. Subsequently, it was checked the biological plausibility of the reported energy intakes, classifying all participants as plausible reporters or under-reporters. Exploratory factor analysis was used to determine the participants' dietary patterns. The Mann-Whitney test assessed the reported energy and nutrient intakes between plausible reporters and under-reporters groups. The Z-test assessed the variables of plausible reporters or under-reporters in relation to all participants of the study. Results Six dietary patterns were determined for all participants of study. After excluding information from under-reporting women, only two dietary patterns remained similar to those of all participants, while three other dietary patterns presented different conformations from food subgroups to plausible reporters. The reported energy intake did not present difference for the subgroups of fruits, leaf vegetables and vegetables. However, the energetic value reported for the other food subgroups was higher for the plausible reporters. Conclusion The under-reporting of energy intake influenced the determination of dietary patterns of obese women waiting for bariatric surgery.

RESUMO Objetivo Esta pesquisa buscou verificar a interferência da subnotificação do consumo energético na determinação do padrão alimentar e consumo de nutrientes, relatados por mulheres obesas na fila de espera para cirurgia bariátrica. Métodos Participaram do estudo 412 mulheres com idade entre 20 e 45 anos e índice de massa corporal entre 35 e 60 kg/m2, que aguardavam na fila de espera de cirurgia bariátrica. Foram utilizadas informações de três registros do consumo alimentar, da atividade física de 24 horas e do peso corporal e altura, para estimativa da Ingestão Energética Relatada, Nível de Atividade Física e Gasto Energético de Repouso das participantes e subsequente verificação da plausibilidade biológica do consumo energético. As mulheres foram agrupadas em notificadoras plausíveis e subnotificadoras. A análise fatorial exploratória foi utilizada para classificar os padrões alimentares. Os valores relatados de energia e nutrientes entre os grupos de notificadoras plausíveis e subnotificadoras foram avaliados por meio do teste de Mann-Whitney. O Teste de hipótese Z avaliou as variáveis das notificadoras plausíveis ou subnotificadoras em relação a todas as participantes do estudo. Resultados Seis padrões alimentares foram determinados para todas as participantes do estudo. Após excluir as informações das mulheres subnotificadoras, apenas dois padrões alimentares mantiveram-se similares aos de todas as participantes, ao passo que outros três padrões alimentares apresentaram diferentes conformações de subgrupos alimentares para as notificadoras plausíveis. A ingestão energética relatada não apresentou diferença para os subgrupos das frutas, hortaliças e legumes. Porém, o valor energético relatado para os demais subgrupos alimentares foi maior para as notificadoras plausíveis. Conclusão A subnotificação do consumo energético influenciou a determinação de padrões alimentares de mulheres obesas na lista de espera para cirurgia bariátrica.

Association of 5-HT2C (rs3813929) and UCP3 (rs1800849) gene polymorphisms with type 2 diabetes in obese women candidates for bariatric surgery.

OBJECTIVE: Obesity can cause systemic arterial hypertension (SAH) and type 2 diabetes mellitus (DM2) factor that is also influenced by genetic variability. The present study aims to investigate the association between gene polymorphisms related with obesity on the prevalence of SAH and DM2 in the preoperative period and 1 year after Roux-en-Y gastric bypass surgery. SUBJECTS AND METHODS: In total, 351 obese women in a Brazilian cohort completed the study. The clinical diagnosis of SAH and DM2 was monitored from medical records. Twelve gene polymorphisms (rs26802; rs572169; rs7799039; rs1137101; rs3813929; rs659366; rs660339; rs1800849; rs7498665; rs35874116; rs9701796; and rs9939609) were determined using real-time polymerase chain reaction and TaqMan assay. RESULTS: In the preoperative period, prevalence of SAH and DM2 was 57% and 22%, respectively. One year postoperatively, 86.8% subjects had remission of DM2 and 99.5% had control of SAH. Subjects with T allele from the serotonin receptor gene (5-HT2C, rs3813929) had five times greater chance of DM2, and the CC genotype from uncoupling protein 3 gene (UCP3, rs1800849) had three times greater chance in the preoperative period. CONCLUSION: These findings indicate that polymorphisms rs3813929 and rs1800849 from 5-HT2C and UCP3 genes were related to DM2 prevalence among the Brazilian obese women candidates for bariatric surgery.

Micronutrient supplementation in gastric bypass surgery: prospective study on inflammation and iron metabolism in premenopausal women / Suplementación con micronutrientes en pacientes con cirugía de bypass gástrico: estudio prospectivo sobre la inflamación y el metabolismo del hierro en mujeres premenopáusicas

Background: Low-grade chronic inflammation in morbid obesity is associated with impaired iron metabolism. Bariatric surgery is effective in weight loss; however, it can induce specific nutritional deficiencies, such as iron, especially in premenopausal women. Alternatively, after surgery, there is an improvement in systemic inflammation, raising questions concerning the dosages of micronutrient supplementation. Objectives: This study aimed to assess the effect of two micronutrient supplementation schemes before and 6 months after a Roux-en-Y gastric bypass (RYGB) surgery on inflammation and iron metabolism in premenopausal women. Methods: This prospective study included 45 premenopausal women (aged 20-45 years; body mass index [BMI] ≥ 35 kg/m2) divided into two supplementation schemes: group 1 (n = 34): daily supplemental dose of 1 RDA 30 days before surgery and 2 RDAs during the six months following surgery; and group 2 (n = 11): daily supplementation of 1 RDA during the 6 months postsurgery. Anthropometry, dietary intake, inflammation, and iron metabolism were monitored. Results: Evident reductions in BMI, high-sensitivity C-reactive protein, and ferritin levels for both groups occurred 6 months after surgery. Additionally, anemia was 9% in both groups after surgery. However, group 1 exhibited an increased transferrin saturation index and reduced transferrin levels. Multivariate regression analysis suggested serum iron, hepcidin, and iron intake determined ferritin values before and after RYGB surgery. Conclusion: Six months after RYGB, systemic inflammation was reduced in both supplementation schemes. However, supplementation of 1 RDA before and 2 RDAs after surgery resulted in better improvements on iron metabolism (AU)

Introducción: la inflamación crónica de bajo grado en la obesidad mórbida se asocia con una alteración del metabolismo del hierro. La cirugía bariátrica es eficaz en la pérdida de peso, sin embargo, puede inducir deficiencias específicas nutricionales, como es el caso del hierro, especialmente en las mujeres premenopáusicas. Por otra parte, después de la cirugía, hay una mejora en la inflamación sistémica, planteando el tema de las dosis de suplementos de micronutrientes. Objetivos: este estudio tuvo como objetivo evaluar el efecto de dos esquemas de suplementación de micronutrientes antes y 6 meses después de una cirugía de by-pass gástrico con Y de Roux (RYGB) sobre la inflamación y el metabolismo del hierro en las mujeres premenopáusicas. Métodos: estudio prospectivo que incluyó 45 mujeres premenopáusicas (edades 20-40 años, índice de masa corporal [IMC] ≥ 35 kg/m2) divididos en dos esquemas de suplementación: grupo 1 (n = 34): dosis suplementaria diaria de 1 vez las RDA 30 días antes de la cirugía y 2 veces las RDA durante los seis meses posteriores a la cirugía; y el grupo 2 (n = 11): la suplementación diaria de 1RDA durante los 6 meses después de la cirugía. Se monitorizaron las medidas antropométricas, la ingesta alimentaria, la inflamación y el metabolismo del hierro. Resultados: se observó una disminución en el IMC, la proteína C reactiva de alta sensibilidad y los niveles de ferritina en ambos grupos después de 6 meses tras la cirugía. Además, la anemia fue del 9% en ambos grupos tras de la cirugía. Sin embargo, el grupo 1 exhibió un incremento del índice de saturación de transferrina y una reducción en los niveles de transferrina. En el análisis multivariante se apreció que los niveles de hierro sérico, hepcidina y la ingesta de hierro determinaron los valores de ferritina antes y después de la cirugía. Conclusión: seis meses después de RYGB, la inflamación sistémica se redujo en ambos esquemas de suplementación. Sin embargo, la suplementación de 1 vez las RDA antes y 2 veces las RDA después de la cirugía consiguió mejorar el metabolismo del hierro (AU)

Ferritin in hypertensive and diabetic women before and after bariatric surgery / La ferritina en mujeres hipertensas y diabéticas antes y después de la cirugía bariátrica

In addition to its important role as marker of iron stores, serum ferritin is a marker of systemic inflammation, and obesity has been associated with chronic inflammation. Objective: To verify, six months after surgery, the effect of bariatric surgery on the serum ferritin of women who were hypertensive, diabetic, or comorbidity free before surgery. Sample and methods: This retrospective study included 200 women aged 20 to 45 years, with a body mass index (BMI) equal to or greater than 35 kg/m2, submitted to Roux-en-Y gastric bypass (RYGB). Seventy of these women were hypertensive, forty had type 2 diabetes (T2D), and ninety were comorbidity free (CF). They were assessed before and six months after surgery. Anthropometric, laboratory (serum ferritin and hemoglobin), and comorbidity- related data were collected from their medical records. Results: Before surgery, women with comorbidities were older, the hypertensives had higher BMI, and the diabetics had higher serum ferritin levels than the CF women. The study comorbidities had resolved in 68% of the hypertensive women and 86% of the diabetic women six months after RYGB. Also at this time, the serum ferritin of hypertensive women decreased from 110.1±86.3 to 88.7±80.5 ng/dL and of diabetic women, from 164.8±133.4 to 101.2±97.7 ng/dL (p<0.05); hemoglobin also decreased in hypertensive and CF women (p>0.05). Conclusion: High ferritin in premenopausal obese women was associated with the main obesity-related comorbidities, and these comorbidities determined the reduction of serum ferritin after bariatric surgery (AU)

Además de importante marcador de las reservas de hierro, la ferritina sérica es un marcador de la inflamación sistémica, mientras que la obesidad se ha asociado con la inflamación crónica. Objetivo: Identificar, después de 6 meses, el efecto de la cirugía bariátrica sobre los niveles de ferritina sérica en hipertensos, diabéticos o sin estas comorbilidades preoperatorias mujeres. Pacientes y métodos: Los autores realizaron un estudio retrospectivo de 200 mujeres sometidas a bypass gástrico en Y de Roux (BGYR), con edades comprendidas entre 20 y 45 años, con un índice de masa corporal (IMC) superiora 35 kg/m2, con hipertensión arterial (HA, n = 70), ladiabetes mellitus tipo 2 (DM2, n = 40) y sin comorbilidades(SC, n = 90) fueron evaluados antes y 6 meses después de BGYR. Antropométricas, de laboratorio (ferritina sérica y hemoglobina) y la información de comorbilidad se recogió de la historia clínica electrónica. Resultados: Antes de la cirugía, las mujeres con comorbilidades eran mayores, tenían mayores hipertensos IMC, niveles más altos de ferritina diabéticos en relación con el grupo SC. La resolución de las comorbilidades después de 6 meses de DGYR ocurrió en el 68 % de las mujeres con hipertensión y el 86 % de los diabéticos. 6 meses después de la cirugía, se observó una disminución de la ferritina sérica en mujeres con comorbilidades de 110,1 ± 86,3 a 88,7 ± 80,5 ng/dl en el grupo con hipertensión y 164,8 ± 133,4 a 101 2 ± 97,7 ng/dl en DM2 (p < 0,05) y la hemoglobina, excepto en los pacientes diabéticos (p > 0,05). Conclusión: El aumento de la ferritina en mujeres obesas en el periodo de premenopausia se relacionan con lasprincipales comorbilidades de la obesidad, y la presencia de estas comorbilidades fue fundamental en la reducción de la ferritina sérica después de la cirugía bariátrica (AU)

Subnotificação da ingestão alimentar e fatores associados / Food intake underreporting and associated factors

OBJETIVO: Avaliar a subnotificação da ingestão energética e fatores associados entre mulheres que aguardam a cirurgia bariátrica no serviço público de saúde de uma cidade do interior do estado de São Paulo-Brasil. MÉTODOS: A amostra foi composta por 100 obesas. A ingestão energética (IE) e o nível de atividade física (NAF) foram estimados por meio de três recordatórios de 24 horas. O gasto energético em repouso(GER) foi medido pela calorimetria indireta. A razão ingestão energética relatada e gasto energético de repouso (IErel: GER) foi usada para avaliar a subnotificação, sendo o resultado comparado com pontos de corte derivados da equação de Goldberg. A associação entre a subnotificação e as características das mulheres foi avaliada pelo teste Z e a comparação entre os dados não paramétricos foi feita pelo teste de Mann-Whitney. Resultados e Conclusões: Houve diferença significativa entre os grupos de subnotificadoras e não subnotificadoras para a razão IErel:GER (p<0,0001). A proporção de subnotificação da ingestão energética foi de 47%, sendo maior entre mulheres que relataram níveis maiores de atividade física (p=0,006) e menor entre as que relataram níveis menores de atividade física (p=0,001). Quanto à escolaridade a maior proporção de subnotificação foi entre mulheres com ensino fundamental (p=0,002) e menor entre aquelas com ensino médio (p=0,03). A proporção de subnotificação também foi maior entre mulheres da classe econômica C ou inferior (p=0,049). As candidatas à cirurgia bariátrica apresentaram altas taxas de subnotificação da ingestão energética, especialmente a parcela das mulheres com menor escolaridade, baixa classe econômica e/ou mais ativas

OBJECTIVE: To assess the energy intake underreporting and associated factors among women waiting for bariatric surgery at the public healthcare service of a city in the state of São Paulo-Brazil. Methods: The sample consisted of 100 obese women.Three 24-hour recalls were used to estimate energy intake (EI) and physical activity level (PAL). Resting metabolic rate (RMR) was determined by indirect calorimetry.The ratio between reported energy intake and resting metabolic rate (rEI:RMR) wasused to assess the underreporting and the results were compared with the cut-off points obtained by the Goldberg equation. The association between under reporting and the women's characteristics was assessed by the Z-test and the non-parametric data were compared by the Mann-Whitney test. Results and Conclusions: The ratiorEI:RMR differed significantly between the underreporting and non-under reporting groups (p<0.0001). Forty-seven percent of women underreported their energy intake being that, this proportion was higher among women who reported higher physical activity levels (p=0.006) and lower among women who reported lower physical activity levels (p<0.001). The proportion of underreporting was also higher among women who had only completed elementary school (p<0.002) and lower among those who completed high school (p <0.03). Women belonging to the socioeconomic class Cor below also presented a higher proportion of underreporting (p<0.049). Bariatric surgery candidates present high rates of energy intake underreporting, especially those with lower education levels, of low socioeconomic classes and/or higher physical activity levels

Calibração de antropometristas para pesquisa em vigilância alimentar e nutricional / Calibration of anthropometrists for research on food and nutrition surveillance

OBJECTIVE: The quality control of anthropometric measurements results in reliable and accurate data. The objective of the present study was to develop a training approach for research and assess the quality of anthropometric measurements performed by 42 evaluators during the training process. METHODS: The evaluators were selected from undergraduate nutrition courses and submitted to a training given by a single supervisor - a nutritionist. The training course was followed by two months of studying and practicing of anthropometric assessments aided by professors of 20 partner institutions and a teaching video. The evaluators were later reassessed by the same supervisor. A total of 330 children aged zero to two years and 420 subjects over two years participated in the evaluators' calibration, totaling 840 measurements. Each evaluator assessed 20 subjects (50% children aged zero to two years) and the supervisor repeated the anthropometric measurements. Technical error of measurement (TEM) was used for the statistical assessment of inter-evaluators' calibration. RESULTS: The measurements taken by 37 evaluators were accurate. Conclusion: The proposed training approach developed the anthropometric skills of the undergraduate students, enabling them for field studies

O objetivo do trabalho foi desenvolver uma abordagem de treinamento para pesquisa e avaliar a qualidade das medidas antropométricas obtidas por 42 avaliadores no processo de treinamento. MÉTODO: Os avaliadores foram selecionados em cursos de graduação em Nutrição e submetidos a um treinamento ministrado por um único supervisor, nutricionista, seguido de dois meses para estudo e prática da avaliação antropométrica, auxiliados por professores de 20 instituições parceiras e apoio de um vídeo didático, sendo posteriormente reavaliados pelo mesmo supervisor. A calibração dos avaliadores ocorreu em 330 crianças de 0 a 2 anos e 420 indivíduos maiores de 2 anos, totalizando 840 aferições, sendo que cada avaliador aferiu 20 indivíduos (50% crianças menores de 2 anos), com repetição da medida pelo supervisor. O método estatístico para avaliação da calibração interavaliadores foi a Técnica do Erro da Medida (TEM). RESULTADOS: As medidas de 37 avaliadores estavam acuradas. CONCLUSÃO: A abordagem de treinamento proposta resultou no desenvolvimento de habilidades antropométricas dos alunos de graduação, tornando-os aptos à realização de pesquisa de campo

Cobertura populacional do Sistema de Vigilância Alimentar e Nutricional no Estado de São Paulo, Brasil / Population coverage of the food and nutrition surveillance system in the state of São Paulo, Brazil

O objetivo deste artigo é estimar a cobertura populacional do Sistema de Vigilância Alimentar e Nutricional (SISVAN) nos diferentes estágios de vida e avaliar seu funcionamento no estado de São Paulo. O estudo incluiu 65 municípios divididos em 14 regiões do estado. A cobertura do SISVAN foi estimada a partir de dados de monitoramento do estado nutricional disponíveis nos relatórios públicos, e do número de usuários que frequentam os serviços públicos de saúde. O total de usuários foi obtido pela diferença entre o total de habitantes e o número de beneficiários de planos de saúde privados. A maioria das regiões apresentou uma cobertura reduzida (<10%). Cerca de 57% revelaram cobertura entre 5 e 10%. Constatou-se uma preponderância de registros do estado nutricional de crianças para todas as regiões do Estado. Chama a atenção a reduzida cobertura entre os idosos, que é inexistente ou próxima de zero na maioria das regiões. Apesar dos esforços empreendidos pelo governo visando à ampliação e à qualificação do SISVAN, o monitoramento nutricional no estado de São Paulo ainda é insuficiente. Esta condição compromete sua utilização na elaboração de políticas efetivas na área de alimentação e nutrição.

This article sets out to estimate the population coverage of the Food and Nutrition Surveillance System (SISVAN) at different phases of life and to evaluate its operation in the state of Sao Paulo. The study included 65 cities divided in 14 state regions. The coverage of SISVAN was estimated using data from nutritional status monitoring available in public reports and on government websites, as well as the number of users attended by the public health services. Total users of public health services were obtained by the difference between the total number of inhabitants of 65 cities and the number of beneficiaries of private health plans. Most regions presented reduced population coverage (< 10%). Approximately 57% revealed population coverage of between 5 and 10%. There was a preponderance of records of the nutritional status of children for all regions of the state. A startling statistic was the low coverage for the elderly population, which was zero or near zero in most regions. Despite the efforts by the government to expand and enhance SISVAN, nutritional monitoring in Sao Paulo is still insufficient. This condition hinders the use of SISVAN to produce effective changes in food and nutrition policies.

One-hundred days monitoring patients submitted to hematopoietic stem cell transplantation: Events of metabolic syndrome / Cem dias de monitoramento de pacientes submetidos ao transplante de células-tronco hematopoéticas: eventos da síndrome metabólica

Objective This study assessed early manifestations of metabolic syndrome determinants in patients submitted to hematopoietic stem cell transplantation. Methods Twenty-seven individuals participated in the study (20 with autologous and 7 with allogeneic hematopoietic stem cell transplantation). Anthropometric variables and biochemical indicators of lipid and glucose metabolism were determined before and 100 days after hematopoietic stem cell transplantation. ResultsThe mean total cholesterol (p=0.086), very low density lipoprotein-cholesterol (p=0.069) and triglycerides (p=0.086) of all patients did not change significantly between the two study periods, but when the patients were separated by type of hematopoietic stem cell transplantation, triglycerides and very low density lipoprotein-cholesterol were close to the critical level of significance for individuals with allogeneic hematopoietic stem cell transplantation (p=0.060) and total cholesterol was significant in individualswith autologous hematopoietic stem cell transplantation (p=0.027). Anthropometric variables did not change significantly between before and 100 days after hematopoietic stem cell transplantation. Conclusion Metabolic syndrome risk factors may be associated with lipid metabolism in the early phase of allogeneic and autologous hematopoietic stem cell transplantation.

Objetivo: Este estudo avaliou as manifestações precoces de fatores determinantes da síndrome metabólica em pacientes com transplante de células-tronco hematopoéticas. Métodos: Vinte e sete indivíduos participaram do estudo (20 autólogos e 7 alogênicos). Variáveis antropométricas e indicadores bioquímicos do metabolismo glicídico e lipídico foram determinados antes e após 100 dias do transplante. Resultados: A média de colesterol total (p=0,086), lipoproteínas de muito baixa densidade-colesterol (p=0.069) e triglicerides (p=0.086) de todos os pacientes não sofreu alteração significativa entre os dois perídos, porém, quando os pacientes foram separados pelo tipo de transplante de células-tronco hematopoéticas, os triglicerídeos e o lipoproteínas de muito baixa densidade-colesterol apresentaram-se próximos do nível crítico de significância para os indivíduos com transplante alogênico (p=0,06) e o colesterol total aumentou significativamente entre os indivíduos autólogos (p=0,027). As variáveis antropométricas não alteraram significativamente na comparação antes e após transplante de células-tronco hematopoéticas. Conclusão: Os fatores de risco para síndrome metabólica podem ser associados com o metabolismo de lipídios na fase inicial do transplante alogênico e autólogo.
