ABSTRACT Objective To evaluate the association between the degree of food processing, overweight, and abdominal obesity in adolescents. Methods This is a cross-sectional study, with 576 adolescents aged 10 to 17 years, of both sexes. Food consumption was collected using the Food Frequency Questionnaire and foods classified as in natura or minimally processed, processed foods associated with culinary ingredients, and ultraprocessed foods. Sociodemographic data, body mass index, waist circumference and waist-to-height ratio were collected. The analysis was evaluated by the Mann-Whitney test and prevalence ratio with 95% confidence interval, considering p<0.05. Results An intake above the third quartile of processed foods associated with culinary ingredients (prevalence ratio of 1.64; 95%CI: 1.12-2.42) and ultraprocessed (prevalence ratio of 1.58; 95%CI: 1.07-2.34) was associated with a higher prevalence of overweight. Consumption above the third quartile of ultraprocessed foods was associated with a higher prevalence of abdominal obesity, assessed by waist circumference (prevalence ratio of 2.48; 95%CI: 1.41-4.36), and waist-height ratio (prevalence ratio of 2.09; 95%CI: 1.11-3.92). Conclusion A higher consumption of processed foods associated with culinary ingredients was related to being overweight, and ultraprocessed foods with overweight and abdominal obesity.

RESUMO - RACIONAL: Os pacientes cirúrgicos constituem um grupo de indivíduos comumente subdiagnosticado e subtratado, onde o comprometimento nutricional pode ser tanto um achado preexistente quanto decorrente do estado hipercatabólico e hipermetabólico. OBJETIVO: Avaliar a prevalência de desnutrição, de acordo com os critérios GLIM (Global Leadership Initiative on Malnutrition), e sua associação com fatores clínicos e nutricionais, em indivíduos internados em uma unidade cirúrgica de um hospital geral. MÉTODOS: Estudo transversal, retrospectivo, envolvendo pacientes no pré-operatório por doenças gastrointestinais. Foram coletados dados demográficos, clínicos e nutricionais de pacientes adultos e idosos admitidos entre março e dezembro de 2019 em uma unidade cirúrgica. O risco nutricional foi avaliado pela ferramenta Nutritional Risk Screening (NRS 2002). A prevalência de desnutrição foi encontrada a partir dos critérios GLIM. Modelos de regressão logística binária foram realizados para determinar a associação entre o diagnóstico de desnutrição pelo método GLIM e variáveis clínicas e nutricionais. RESULTADOS: A maior parte da amostra apresentou risco nutricional (50,2%) conforme NRS 2002. A prevalência de desnutrição pelos critérios GLIM foi 32,3%, sendo a desnutrição grave predominante (21,2%) em todas as faixas etárias. Verificou-se associação entre a desnutrição e o risco nutricional detectado pela NRS-2002 (OR: 5,791; IC5% 3,201-10,478). Observou-se predominância de pacientes candidatos a cirurgias oncológicas (64%) e estes apresentaram maiores chances de receber o diagnóstico de desnutrição (OR: 2,068; IC95%: 1,161-3,683), após ajuste estatístico. CONCLUSÃO: Foi Identificado importante prevalência de risco nutricional avaliado pela NRS-2002 e de desnutrição pelo método GLIM, principalmente na forma grave. Além disso, os pacientes no pré-operatório com risco nutricional, detectado por meio da ferramenta de triagem nutricional NRS 2002, e aqueles candidatos à cirurgia oncológica têm mais chances de serem diagnosticados como desnutridos pelos critérios GLIM.

ABSTRACT - BACKGROUND: Surgical patients constitute a group of individuals who are commonly underdiagnosed and undertreated, where nutritional impairment can be either a preexisting finding or a result of the hypercatabolic and hypermetabolic state. OBJECTIVE: The purpose of this study was to assess the prevalence of malnutrition, according to the GLIM criteria, and its association with clinical and nutritional factors, in individuals admitted to a surgical unit of a general hospital. METHODS: A cross-sectional, retrospective study was conducted, involving patients in the preoperative period due to gastrointestinal diseases. Demographic, clinical, and nutritional data were collected from adult and elderly patients admitted to a surgical unit between March and December 2019. Nutritional risk was assessed using the Nutritional Risk Screening tool (NRS-2002). The prevalence of malnutrition was found using the GLIM criteria. Binary logistic regression modeling was performed to determine the association between the diagnosis of malnutrition using the GLIM method and clinical and nutritional variables. RESULTS: The majority of the sample presented nutritional risk (50.2%) according to the NRS-2002. The prevalence of malnutrition according to the GLIM criteria was 32.3%, with severe malnutrition being predominant (21.2%) in all age groups. There was an association between malnutrition and nutritional risk detected by the NRS-2002 (OR: 5.791; 95%CI 3.201-10.478). There was a predominance of patients undergoing cancer surgery (64%) and these patients were more likely to be diagnosed with malnutrition (OR: 2.068; 95%CI: 1.161-3.683), after statistical adjustment. CONCLUSION: An important prevalence of nutritional risk assessed by the NRS-2002 and of malnutrition assessed by the GLIM method was identified, especially in its severe form. In addition, preoperative patients with nutritional risk, as detected using the NRS-2002 nutritional screening tool, and candidates for oncologic surgery are more likely to be diagnosed as malnourished using the GLIM criteria.

RESUMO JUSTIFICATIVA E OBJETIVOS: Ao considerar a conexão bidirecional entre intestino e cérebro, o presente estudo avaliou a associação entre enxaqueca, intolerância à lactose e constipação intestinal em pacientes em estado migranoso. MÉTODOS: Trata-se de um estudo transversal e retrospectivo que incluiu 97 pacientes com idade igual ou superior a 20 anos. O impacto da dor foi avaliado pelos questionários: Migraine Disability Assessment e Headache Impact Test-6. A intensidade da dor foi avaliada pela escala analógica visual. Os testes Qui-quadrado e Student-t foram utilizados para análise estatística. RESULTADOS: A amostra foi composta por 88,7% de mulheres, 56,8% com excesso de peso, 76,3% sedentários, 32% constipados e 23,7% intolerantes à lactose. Os constipados apresentaram maiores médias de impacto da dor pelo Headache Impact Test-6 (67,6±5,3) e pelo Migraine Disability Assessment (36,7±26,3) e intensidade da dor (8,9±1,3) do que os não constipados. Os pacientes intolerantes à lactose apresentaram maior média de tempo de enxaqueca (19,9±14,2) em relação aos tolerantes à lactose. Os pacientes constipados apresentaram maiores prevalências de excesso de peso (58,1 e 65,2%) e obesidade abdominal (70,0 e 68,2%) e intolerantes em relação aos sem constipação intestinal e aos tolerantes à lactose, respectivamente. CONCLUSÃO: Embora identificadas prevalências consideráveis de constipação intestinal e intolerância à lactose na amostra avaliada, além de maiores médias de pontuação nos questionários utilizados para impacto e intensidade da dor nos pacientes constipados e de maior tempo de diagnóstico da migrânea nos intolerantes à lactose, não houve significância estatística na associação entre enxaqueca e esses distúrbios gastrointestinais.

ABSTRACT BACKGROUND AND OBJECTIVES: Considering the bidirectional connection between intestine and brain, the present study examined the association between migraine, lactose intolerance, and intestinal constipation in patients with status migrainosus. METHODS: This is a cross-sectional retrospective study that included 97 patients aged 20 years or older. The impact of pain was assessed by the Migraine Disability Assessment and the Headache Impact Test-6 questionnaires. The pain intensity was measured by the visual analog scale. Chi-square and Student-t tests were used for the statistical analysis. RESULTS: The sample consisted of 88.7% women, 56.8% overweight, 76.3% sedentary, 32% constipated and 23.7% lactose intolerant. Higher pain intensity (8.9±1.3) and impact pain mean was assessed by the Headache Impact Test-6 (67.6±5.3) and the Migraine Disability Assessment (36.7±26.3) in constipated patients compared to those without constipation. Lactose-intolerant patients presented higher migraine mean time (19.9±14.2) compared to lactose tolerant patients. Constipated and lactose intolerant patients presented higher prevalence of overweight (58.1 and 65.2%) and abdominal obesity (70.0 and 68.2%) compared to non-constipated and lactose tolerant patients, respectively. CONCLUSION: Although were observed in the evaluated sample a considerable prevalence of constipation and lactose intolerance, higher mean scores in the questionnaires used for pain impact and intensity in constipated patients and longer migraine diagnosis time in those with lactose-intolerance, there was no statistical significance in the association between migraine and these two gastrointestinal disorders.
