- Índice inflamatório da dieta em indivíduos com sucesso na gestão do peso: associação com indicadores de comportamento alimentar e depressãoPublication . Rodrigues Paulino, Ana Catarina; Policarpo, Sara; Santos, InêsIntrodução: A manutenção do peso perdido a longo prazo é um desafio, pelo que é essencial compreender os fatores envolvidos. Objetivos: Analisar o índice inflamatório da dieta de indivíduos portugueses com sucesso na gestão do peso, explorando a sua associação com a magnitude de perda de peso e o índice de massa corporal, e com indicadores de comportamento alimentar e depressão, assim como explorar a relação destas variáveis entre si. Metodologia: Foram utilizados dados do Registo Nacional de Controlo do Peso (n=205; 59,5% mulheres; 38,97 ± 10,82 anos; 25,76 ± 3,99 kg/m2). A ingestão alimentar foi avaliada através do Questionário semi-quantitativo de Frequência Alimentar, a partir do qual foi calculado o índice inflamatório da dieta; o comportamento alimentar (alimentação emocional e externa) através do Dutch Eating Behaviour Questionnaire; e o nível de depressão através do Beck Depression Index. Resultados: O índice inflamatório da dieta variou de -3,67 a 3,64. Observou-se uma associação negativa entre o índice inflamatório da dieta e a magnitude de perda de peso na amostra total (r=-0,151, p=0,043) e no sexo feminino (r=-0,225, p=0,021). Relativamente ao índice de massa corporal, encontrou-se uma associação positiva com o índice de depressão (r=0,276, p<0,001) e com a alimentação emocional (r=0,284, p<0,001). Adicionalmente, o índice de depressão associou-se de forma positiva com a alimentação externa (r=0,322, p<0,001) e emocional (r=0,403, p<0,001). Conclusões: Uma alimentação anti-inflamatória parece associar-se a maior magnitude de perda de peso em mulheres com sucesso na manutenção do peso perdido, o que sugere que o índice inflamatório da dieta poderá ser um fator relevante no que diz respeito à gestão do peso nesta população em particular. À medida que o índice de massa corporal aumenta, parece aumentar também o nível de depressão e a alimentação emocional não só nestas mulheres, mas também nos homens. Uma melhor compreensão da relação entre estes e outros fatores envolvidos na gestão do peso com sucesso poderá́ contribuir para o delineamento de intervenções do estilo de vida mais apropriadas.
- Capacitação para hábitos alimentares adequados em contexto de cirurgia bariátricaPublication . Camolas, JoséTrindade e Trindade defendem a ilicitude de retardar a indicação para cirurgia bariátrica em doentes portadores de obesidade grave. Reportando-se ao trabalho de Ribeiro et al, destacam que os resultados derivam de um estudo transversal, não sendo possível inferir se o desempenho cognitivo abaixo do valor médio da população portuguesa (para a memória imediata, visuoperceção, resistência à interferência e flexibilidade cognitiva), a reserva cognitiva maioritariamente baixa e a significativa elevação do desajustamento emocional são causa ou consequência da obesidade grave.
- NAFLD nutritional management: results from a multidisciplinary approachPublication . Policarpo, Sara; Machado, Mariana; Pires Barreira, David; Cortez-Pinto, HelenaIntroduction: Lifestyle changes are the mainstay treatment of nonalcoholic fatty liver disease (NAFLD). We aimed to assess the magnitude of weight loss in a group of NAFLD patients followed on a combined lifestyle intervention by a multidisciplinary team. Methods: Patients were assessed before and after a 12-month dietary intervention (Mediterranean diet aiming at weight loss). Patients who received a structured dietary plan along with general lifestyle recommendations were designated as the multidisciplinary treatment (MdT) group. Patients who declined follow-up still received general lifestyle recommendations and were designated as the conventional treatment group, being used as a control group. Results: From the 77 patients with documented NAFLD, 31.2% of patients were overweight and 55.8% obese; 66 patients constituted the MdT group and 11 the conventional treatment group. After 3 months, 89% of patients lost weight; at 6 months, 75.4% maintained the weight lost. At 12 months, 65% of patients still decreased their weight, with 92.2% of patients in the MdT group still maintaining a lower weight than baseline versus just 50% in the conventional group (p = 0.008). Only patients in the MdT group presented a weight loss higher than 10% (9.6%; n = 6). At 12 months patients in the MdT group presented an average reduction of 4.2 kg versus a reduction of just 0.6 kg in the conventional treatment group (p = 0.016). The MdT group, but not the conventional group, presented significant differences in liver enzymes at 12 months compared to baseline. Conclusion: Adherence to a multidisciplinary approach, compared to management solely by a hepatologist, in NAFLD patients, is effective with greater weight loss after a 12-month follow-up and a lower rate of weight gain recurrence.
- Digital home-based multidisciplinary cardiac rehabilitation: how to counteract physical inactivity during the COVID-19 pandemicPublication . Pinto, Rita; Pires, Madalena; Borges, Mariana; Liñan Pinto, Mariana; Guerreiro, Catarina Sousa; Miguel, Sandra; Santos, Olga; Ricardo, Inês; Cunha, Nelson; Alves da Silva, Pedro; Correia, Ana Luísa; Fiúza, Sílvia; Caldeira, Edite; Salazar, Fátima; Rodrigues, Carla; Cordeiro Ferreira, Mariana; Afonso, Gisela; Araújo, Graça; Martins, Joana; Ramalhinho, Marta; Sousa, Paula; Pires, Susana; Jordão, Alda; Pinto, Fausto J.; Abreu, AnaIntroduction and objectives: Center-based cardiac rehabilitation (CR) programs have been forced to close due to COVID-19. Alternative delivery models to maintain access to CR programs and to avoid physical inactivity should be considered. The aim of this study was to assess physical activity (PA) levels after completing a home-based digital CR program. Methods: A total of 116 cardiovascular disease (CVD) patients (62.6±8.9 years, 95 male) who had been attending a face-to-face CR program were recruited and assessed (baseline and at three months) on the following parameters: PA, sedentary behavior, adherence, cardiovascular and non-cardiovascular symptoms, feelings toward the pandemic, dietary habits, risk factor control, safety and adverse events. The intervention consisted of a multidisciplinary digital CR program, including regular patient assessment, and exercise, educational and psychological group sessions. Results: Ninety-eight CVD patients successfully completed all the online assessments (15.5% drop-out rate). A favorable main effect of time was an increase in moderate to vigorous PA and a decrease in sedentary time at three months. Almost half of the participants completed at least one online exercise training session per week and attended at least one of the online educational sessions. No major adverse events were reported and only one minor event occurred. Conclusion: During the pandemic, levels of moderate to vigorous PA improved after three months of home-based CR in CVD patients with previous experience in a face-to-face CR model. Diversified CR programs with a greater variety of content tailored to individual preferences are needed to meet the motivational and clinical requirements of CVD patients.
- Qual o perfil nutricional e de estilos de vida do doente oncológico? Estudo transversalPublication . Rolão, Andreia; Monteiro Grillo, Isabel; Camilo, Maria; Ravasco, PaulaBackground: Cancer aetiology is multifactorial and risk factors include: obesity, central adiposity, sedentarism, excessive or deficient intake of foods and/or nutrients with pro-carcinogenic effects vs protective ones. Objectives: To evaluate the pattern of nutritional status, life styles, physical activity and diet in a cohort of cancer patients. Methods: This pilot cross-sectional study was conducted in 64 patients referred for radiotherapy at the Radiotherapy Department of the University Hospital of Santa Maria (CHLN). Evaluations were: waist circumference associated with potential cardio-metabolic risk, body composition by Tetrapolar Bioimpedance Analysis (XITRON®), Body Mass Index, dietary intake pattern with a short food frequency questionnaire, physical activity with Jackson questionnaire. Results: The most frequent diagnosis were breast and colorectal cancers; 53% of patients were overweight/obese, and there was a significant correlation between this nutritional pattern and weight gain in comparison with usual weight (p<0.005). There were 78% of patients with a waist circumference above the maximum cut-off limit, indicating moderate/ high cardio-metabolic risk, and most were female patients (87%). The great majority of patients (61%) had excessive fat mass highly above the maximum recommended cut-off value, especially male patients (74%). The dietary pattern was poor in vegetables (55%) and excessive in meat and simple carbohydrates (78%); physical activity was low with a high prevalence of sedentarism. Conclusions: This population presented excessive body weight, excessive fat mass, high cardio-metabolic risk, sedentarism and an unbalanced diet poor in protective foods/nutrients. This population's life styles and nutritional pattern, may be considered of risk in oncology disease. The elevated and growing incidence of cancer in Portugal, reinforces the need for further research in order to identify nutritional factors involved in the etiology/evolution and probably prognosis of cancer.
- Terão os adolescentes portugueses uma alimentação adequada? Resultados do estudo HBSC de 2018Publication . Peralta, Miguel; Marques, Adilson; Gaspar, Susana; Sousa, Joana; Diniz, José Alves; Matos, Margarida Gaspar deThe aim of this study was to characterize the eating habits and body image perceptions of Portuguese young people. A total of 6997 Portuguese young people (51.7% girls) attending the 6th, 8th and 10th grades participated in the study, integrated in the Health Behaviour in School aged Children. Young people were asked about their weight, height, eating habits and body image perception. About 70% of the adolescents presented normal/healthy weight. More girls than boys considered their waist “large” and that their body “fat”. Approximately 45% and 33% of the adolescents reported daily consumption of fruits and vegetables respectively. Consumption of sweets and soft drinks showed an increasing tendency between the 6th and 10th grades and girls reported consuming these foods every day, more than once a day, less frequently than boys. Excessive consumption of sugar together with the scarce consumption of fruits and vegetables reveals frailties in the diet of Portuguese young.
