RÉSUMÉ

ABSTRACT BACKGROUND: Fat, muscle, and bone are endocrine organs capable of affecting the metabolic profile and cardiovascular risk. Relating these components is important to the establishment of early intervention strategies for overweight patients. AIMS: This study aimed to evaluate the influence of body mass components on the metabolic profile and cardiovascular risk in the preoperative period of bariatric surgery. METHODS: A cross-sectional study was conducted with patients admitted for bariatric surgery at a university hospital in the city of Recife, Brazil, between 2018 and 2019. Body composition was determined using dual-energy x-ray absorptiometry. Cardiovascular risk was assessed using the Framingham risk score. Data were collected on anthropometric, clinical, and lifestyle characteristics. The lipid profile (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and triglycerides), blood glucose, and vitamin D were determined using the standard methods of the hospital laboratory. RESULTS: A total of 60 patients were analyzed, 86.7% of whom had comorbidities, 33.3% had moderate/high cardiovascular risk, and 71.4% had vitamin D insufficiency/deficiency. Lower lean body mass (adjusted PR 3.24; 95%CI 1.19-5.77) was independently associated with the severity of obesity. The body mass index and waist circumference were negatively correlated with lean body mass (r=-0.52; p<0.01)/r=-0.36; p<0.01). Lean body mass was negatively correlated with fat mass (r=-0.26; p<0.05), trunk fat (r=-0.29; p<0.05), fasting glucose (r=-0.26; p<0.05), and bone mineral density (r=-0.26; p<0.05). A total of 84.2% of individuals with less trunk fat tended to have low cardiovascular risk (p=0.05). However, physical inactivity (adjusted PR 2.14; 95%CI 1.19-5.54) and the risk of alcohol dependence (adjusted PR 2.41; 95%CI 1.76-4.15) were the only variables independently associated with cardiovascular risk. CONCLUSION: Obese patients in the preoperative period of bariatric surgery with less trunk fat tended to have low cardiovascular risk. However, the other components of body mass were also not associated with cardiovascular risk.


RESUMO RACIONAL: O tecido adiposo, músculos e ossos representam órgãos endócrinos, capazes de interferir no perfil metabólico e risco cardiovascular. Relacionar esses componentes será importante para estratégias de intervenção precoce, em obesos. OBJETIVOS: Avaliar a influência dos compartimentos da massa corporal, sobre o perfil metabólico e risco cardiovascular, no pré-operatório de cirurgia bariátrica. MÉTODOS: Estudo transversal, com pacientes admitidos para cirurgia bariátrica, em hospital universitário. A composição corporal foi avaliada pela absortometria radiológica de dupla energia e o risco cardiovascular pelo escore de risco de Framingham. Foram analisadas variáveis antropométricas, clínicas e de estilo de vida. Foi avaliado perfil lipídico (colesterol total, HDL-c, LDL-c, triglicerídeos), glicemia e vitamina D, utilizando a metodologia padrão. RESULTADOS: Foram analisados 60 pacientes, 86,7% apresentavam comorbidades, 33,3% risco cardiovascular moderado/elevado e 71,4% insuficiência/deficiência de vitamina D. Menor massa corporal magra associou-se à gravidade da obesidade. O índice de massa corpórea e a circunferência da cintura correlacionaram-se negativamente com a massa corporal magra (r=-0,52; p<0,01)/r=-0,36; p<0,01). A massa corporal magra correlacionou-se negativamente com a massa gorda (r=-0,26; p<0,05), gordura troncular (r=-0,29; p<0,05), glicemia de jejum (r=-0,26; p<0,05) e densidade mineral óssea (r=-0,26; p<0,05). Ao todo, 84,2% dos indivíduos com menos gordura troncular apresentaram tendência a baixo risco cardiovascular (p=0,05). Contudo, inatividade física (razão de prevalência ajustada 2,14; IC95% 1,19-5,54) e risco de dependência alcoólica foram as únicas variáveis independentemente associadas ao risco cardiovascular. CONCLUSÕES: Os pacientes obesos em pré-operatório de cirurgia bariátrica com menos gordura troncular, apresentaram tendência a baixo risco cadiovascular. Contudo, o risco cardiovascular também não foi associado aos demais componentes da massa corporal.

RÉSUMÉ

Introduction: Bariatric surgery is considered the most effective obesity treatment. Obese patients have a high prevalence of eating disorders. Objectives: Evaluate the occurrence of eating disorders and eating patterns in candidates for bariatric surgery and associate eating disorders with sociodemographic and clinical characteristics. Methods: A retrospective study was conducted using electronic charts of candidates for bariatric surgery. Data were collected on sex, age, marital status, schooling, occupation, non-communicable diseases, body mass index (BMI), eating disorders, and eating patterns. Results: Among the 281 patients evaluated, eating disorders were detected in 26.7%; 10.3% had binge eating disorder, 6.6% had bulimia nervosa, and 5.3% had the night-eating syndrome. The specific eating patterns were overeating (46.6%), binge eating during periods of stress (9.3%), eating sweets (4%), and snaking (1.3%). BMI ranged from 35.38 to 59.03 kg/m² (mean: 44.37 ± 5.89). All individuals (100%) had systemic arterial hypertension, and 23.3% had type 2 diabetes mellitus or dyslipidemia. Conclusions: The frequency of eating disorders was low in the sample studied, the most common of which was binge eating disorder. Non-communicable diseases were associated with eating disorders. Among the eating patterns observed, the most frequent was overeating (AU)


Introdução: A cirurgia bariátrica é considerada o tratamento mais eficaz para a obesidade. Pacientes obesos possuem elevada prevalência de transtornos alimentares. Objetivos: Avaliar a presença de transtornos alimentares e padrões alimentares em candidatos à cirurgia bariátrica, associando os transtornos alimentares aos dados sociodemográficos e clínicos. Métodos: Estudo retrospectivo de cunho documental, com base em prontuários eletrônicos de pacientes candidatos à cirurgia bariátrica. Foram obtidas variáveis como sexo, idade, estado civil, nível de escolaridade, ocupação, doenças crônicas não transmissíveis, índice de massa corporal (IMC), transtorno e padrão alimentar. Resultados: Dos 281 pacientes avaliados, foi detectado 26,7% de transtornos alimentares, sendo 10,3% transtorno de compulsão alimentar periódica, 6,6% de bulimia nervosa e 5,3% de síndrome do comer noturno. Os padrões alimentares específicos encontrados foram: glutões (46,6%), compulsivos alimentares em períodos de estresse (9,3%), comedores de doces (4%) e beliscadores (1,3%). O IMC variou de 35,38 a 59,03 kg/m² (44,37±5,89), com 100% do grupo apresentando Hipertensão Arterial Sistêmica e 23,3% com Diabetes Mellitus tipo 2 ou dislipidemia. Conclusões: Constatou-se baixa frequência de transtornos alimentares na amostra estudada, sendo o transtorno de compulsão alimentar periódica o mais observado. Doenças crônicas não transmissíveis foram associadas com a presença de transtornos alimentares. Dentre os padrões alimentares observados, os glutões foram os mais frequentes (AU)

RÉSUMÉ

ABSTRACT Objective: To investigate the discriminative power of Nutritional Risk Screening 2002. Methods: A cross sectional study involving one hundred participants aged ≥60 years. The original and adapted versions of Nutritional Risk Screening 2002 and the Mini Nutritional Assessment were used. Nutritional Risk Screening 2002 adaptation consisted of a lower age cutoff (60 years or older) for addition of one extra point to the final score. Results: Screening using Nutritional Risk Screening 2002 revealed higher nutritional risk among patients aged ≥70 years (p=0.009), whereas screening using the adapted version of Nutritional Risk Screening 2002 revealed similar nutritional risk in both age groups (60-69 years and ≥70 years; p=0.117). Frequency of nutritional risk was highest when the Mini Nutritional Assessment was administered (52.7%), followed by the adapted and original versions of Nutritional Risk Screening 2002 (35.5% and 29.1%, respectively). Conclusion: The adapted version of Nutritional Risk Screening 2002 was more effective than the original version. However, further studies are needed to confirm these findings.


RESUMO Objetivo: Avaliar o poder de discriminação diagnóstica da ferramenta Nutritional Risk Screening 2002. Métodos: Estudo transversal com cem participantes com idade ≥60 anos. Foram aplicados o Nutritional Risk Screening 2002 original, o Nutritional Risk Screening 2002 adaptado e o Mini Nutritional Assessment. A adaptação do Nutritional Risk Screening 2002 consistiu em diminuir o critério de idade, incluindo pontuação adicional para 60 anos de idade ou mais. Resultados: Maior risco nutricional ocorreu nos ≥70 anos quando aplicado o Nutritional Risk Screening 2002 original (p=0,009), enquanto o Nutritional Risk Screening 2002 adaptado apresentou risco nutricional semelhante em ambos os grupos (60-69 anos e ≥70 anos; p=0,117). A frequência de risco nutricional foi maior no Mini Nutritional Assessment (52,7%), seguido do Nutritional Risk Screening 2002 adaptado (35,5%) e do Nutritional Risk Screening 2002 original (29,1%). Conclusão: A adaptação do Nutritional Risk Screening 2002 mostrou-se descritivamente mais eficaz do que a original, porém mais estudos devem ser realizados para confirmar os achados.
