EVALUATION OF CARBOHYDRATE AND FIBER CONSUMPTION IN PATIENTS WITH IRRITABLE BOWEL SYNDROME IN OUTPATIENT TREATMENT.

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic functional condition, which main symptoms of pain, discomfort and abdominal distension, constipation, diarrhea, altered fecal consistency and sensation of incomplete evacuation can be influenced by the presence of dietary fiber and fermentable carbohydrates (FODMAPs). This study aimed to assess the relationship between the quantity of fermentable carbohydrates (FODMAP) and fiber consumed by individuals diagnosed with IBS, and their classification according to the Rome III criteria. METHODS: A transversal study was carried out in the Intestinal Outpatient Clinic of the Gastroenterology Discipline of UNIFESP. The nutrients of interest for the study were: fiber, general carbohydrates and FODMAPs, with intake quantity measured in grams, analyzed through portions consumed. A nutrition log was used, along with a semi-quantitative questionnaire of consumption frequency. RESULTS: The sample included 63 adult patients; 21 with constipated IBS, 21 with diarrhea IBS, and 21 with mixed IBS. Carbohydrate intake was suboptimal in 55.6% of patients in all groups; excessive consumption was identified in 38.1% of the diarrhea group, 14.3% of the mixed group and 38.1% of the constipated group. Low consumption of carbohydrates was found in 28.6% of diarrhea patients and 47.6% of the mixed group. A mean intake of 23 g of fiber per day was identified, lower than recommended. CONCLUSION: The study identified a number of inadequacies in the consumption of different nutrients, excessive carbohydrate intake, especially FODMAPs, identified by the respondents as responsible for a worsening of their conditions. By contrast, other food groups such as meat, eggs and dairy were consumed by the sample population in insufficient quantities.

Clinical value of anthropometric estimates of leg lean volume in nutritionally depleted and non-depleted patients with chronic obstructive pulmonary disease.

This study aimed to investigate the clinical usefulness of an anthropometrically based method for estimating leg lean volume (LLV) in patients with chronic obstructive pulmonary disease (COPD) who presented or not with nutritional depletion. We prospectively evaluated a group of forty-eight patients (thirty-eight males) with moderate to severe COPD (Global Initiative for Chronic Obstructive Lung disease stages II-IV) who underwent a 6 min walking test and knee isokinetic dynamometry. Leg lean mass (muscle mass plus bone) was determined by dual-energy X-ray absorptiometry (DEXA) with derivation of its respective volume: these values were compared with those obtained by the truncated cones method first described by Jones and Pearson in 1969. As expected, depleted patients (n 19) had reduced exercise capacity and impaired muscle performance as compared to non-depleted subjects (P < 0.01). The mean bias of the LLV differences between anthropometry and DEXA were 0.40 litre (95 % CI - 0.59, 1.39) and 0.50 litre (95 % CI - 1.08, 2.08) for depleted and non-depleted patients, respectively. Anthropometrically and DEXA-based estimates correlated similarly with muscle functional attributes. A ROC curve analysis revealed that leg height-corrected LLV values had acceptable sensitivity and specificity to identify depleted patients (area under the curve 0.93 (range 0.86-1.00); P < 0.001). Moreover, patients with LLV

Food and Nutrition Surveillance System/SISVAN: getting to know the feeding habits of infants under 24 months of age.

The objective of the Food and Nutrition Surveillance System (SISVAN) is to monitor the food intake of individuals attended by the Brazilian Unified Health System (SUS). The objective of this research was to identify the feeding practices of children under 24 months of age who were attended at Primary Healthcare Units (UBS), using SISVAN, and to assess the relationship with maternal sociodemographic profiles. A cross-sectional study was conducted in order to evaluate 350 children using the Food Consumption Marker Form of SISVAN, and maternal demographic data to identify sociodemographic profiles by exploratory factor analysis. Of the children assessed, 41.1% were under 6 months of age and 98.7% of those between 6 and 23 months had an inadequate intake. Two sociodemographic profiles were found: Profile 1 (mothers with lower income, less education, and recipients of the 'Bolsa Família' conditional family grant program) associated with the consumption of water/tea, cow's milk and salty baby food; and Profile 2 (older mothers with many children and with a larger number of residents in the household) associated with breast milk consumption (p = 0.048). The use of SISVAN made it possible to identify that children had inadequate feeding practices, and Profile 1 appears to be a risk profile for weaning.

Avaliação do consumo alimentar de pacientes com síndrome do intestino irritável em acompanhamento ambulatorial / Evaluation of carbohydrate and fiber consumption in patients with irritable bowel syndrome in outpatient treatment

ABSTRACT BACKGROUND: Irritable bowel syndrome (IBS) is a chronic functional condition, which main symptoms of pain, discomfort and abdominal distension, constipation, diarrhea, altered fecal consistency and sensation of incomplete evacuation can be influenced by the presence of dietary fiber and fermentable carbohydrates (FODMAPs). This study aimed to assess the relationship between the quantity of fermentable carbohydrates (FODMAP) and fiber consumed by individuals diagnosed with IBS, and their classification according to the Rome III criteria. METHODS: A transversal study was carried out in the Intestinal Outpatient Clinic of the Gastroenterology Discipline of UNIFESP. The nutrients of interest for the study were: fiber, general carbohydrates and FODMAPs, with intake quantity measured in grams, analyzed through portions consumed. A nutrition log was used, along with a semi-quantitative questionnaire of consumption frequency.

RESUMO CONTEXTO: A síndrome do intestino irritável é um distúrbio funcional crônico, no qual a dieta, principalmente o teor de fibra dietética e presença de carboidratos fermentativos (FODMAPs) podem influenciar nos principais sintomas: dores, desconforto e/ou distensão abdominal, constipação, diarreia, alteração na consistência das fezes, sensação de evacuação incompleta. OBJETIVO: Este estudo teve como objetivo avaliar as quantidades de carboidratos fermentativos (FODMAP) e fibras consumidas por indivíduos com o diagnóstico de síndrome do intestino irritável e relacionar com seu modelo da classificação, segundo os critérios Roma III. MÉTODOS: Estudo transversal, realizado no Ambulatório de Doenças Intestinais da Disciplina de Gastroenterologia/UNIFESP. Os nutrientes de interesse para o estudo foram: fibras, carboidratos em geral e FODMAPs, calculando-se suas quantidades em gramas, analisadas através das porções consumidas. Os instrumentos de pesquisa utilizados: ficha de acompanhamento nutricional e questionário de frequência alimentar semi-quantitativo. RESULTADOS: A amostra incluiu 63 pacientes adultos, com síndrome do intestino irritável constipado (21), diarreico (21) e misto (21). O consumo de carboidratos mostrou-se inadequado em 55,6% dos indivíduos em todos os grupos; os que tinham alto consumo (38,1%) pertenciam ao grupo diarreia, 14,3% ao misto e 38,1 % ao constipado. Baixo consumo deste nutriente foi 28,6% nos casos de diarreia e 47,6% do misto. Observamos uma ingestão média de fibras equivalente à 23 g/dia, nos três grupos, inferior ao recomendado. CONCLUSÃO: O estudo permitiu reconhecer várias inadequações no consumo dos diferentes grupos de alimentos, particularmente excesso de carboidratos, incluindo os classificados como FODMAPs, identificados pelos doentes como responsáveis pela piora das suas queixas. Em contrapartida, nutrientes fundamentais, como carnes, ovos, leite e derivados estiveram referidos em níveis abaixo do recomendado.

Validation of a quantitative food frequency questionnaire developed to under graduate students.

A validity test of a Food Frequency Questionnaire was carried out using 50 students of health occupation in São Paulo, Brazil. Therefore, a three day dietary record was used as reference method and variables such as energy, macronutrients and dietary fiber were analyzed. The accordance between the Food Frequency Questionnaire and average data from dietary record was tested with kappa statistics and intra-class correlation coefficients (ICC). Limits of agreement were estimated by the Bland-Altman's method. Better results were found for calories (ICC 0.43; 95%CI 0.17 - 0.63) and non-energy-adjusted nutrients, except dietary fiber (ICC 0.34; 95%CI 0.07 - 0.56). The percentage of individuals classified in the same category of consumption was nearly half (49.8%), while only 16% of them were classified in opposite categories. With the exception of lipids, other analyzed variables tended to be overestimated by the Food Frequency Questionnaire. The Food Frequency Questionnaire is recommended as a method of assessing food intake of university students in studies which focus on calorie estimates and also intend to classify groups into intake categories.

[Importance of nutritional counseling and dietary fiber content on glycemic control in type 2 diabetic patients under intensive educational intervention]. / Importância da orientação nutricional e do teor de fibras da dieta no controle glicêmico de pacientes diabéticos tipo 2 sob intervenção educacional intensiva.

OBJECTIVE: To evaluate the importance of nutritional counseling within a set of multidisciplinary interventions. SUBJECTS AND METHODS: Forty-seven patients with type 2 diabetes and hyperglycemia (A1C ≥ 8%), treated conventionally (n = 19, GC) or intensively in six weekly visits (n = 28, GI) were analyzed. We evaluated mean weekly blood glucose (MWG) at baseline and after 6 weeks in both groups. RESULTS: GI reduced caloric (p = 0.001), carbohydrate (p = 0.004), and fat (p = 0.001) intake, and increased fiber consumption, while GC reduced fiber intake (p = 0.018). Glycemic control (MWG ≤ 150 mg/dL) occurred in 75% of GI patients and in 31.6% of CG patients (p = 0.003), with negative correlation between changes in fiber intake and MWG values (r =-0.309; P = 0.035). Results were maintained after 12 weeks. CONCLUSION: Educational short-term intensive intervention was more effective than conventional treatment to achieve glycemic control. Our results also indicate that a more appropriate fiber content in the diet contributes for better blood glucose control in these patients.

[Efect of short term glycemic control on microalbuminuria and glomerular filtration rate in type 2 diabetic patients with poor glycemic control]. / Efeitos do controle glicêmico obtido em curto prazo sobre a microalbuminúria e a filtração glomerular em pacientes diabéticos do tipo 2 com controle glicêmico precário.

INTRODUCTION: The intensive glucose control significantly reduces the risk of microvascular complications, including nephropathy. OBJECTIVES: We assess the impact of glycemic control through calculation of weekly mean glycemia (WMG) and glycemic variability (GV) on 24 hours ambulatory blood pressure (ABPM), urinary albumin excretion (UAE) and glomerular filtration rate (GFR). METHODS: 53 patients with type 2 diabetes mellitus (DM2) were randomly divided into two groups to receive conventional or intensive treatment, which included weekly visits for medication adjustments and implementation of an educational plan for six weeks. RESULTS: We observed glycemic control (WMG < 150 mg/dL and VG < 50) in 75% (n = 21) of the patients on the intervention treatment (IT) (n = 28), and in 24% (n = 6) of the ones on the conventional treatment (CT) (n = 25) (p < 0.001). Considering patients of the two groups, 14 out of the 27 patients who achieved glycemic control showed initial mean systolic blood pressure (SBP) > 120 mmHg which was reduced from 138.4 ± 10.1 to 127.8 ± 11.6 mmHg (p = 0.023) at the end of week six. Reductions in SBP and diastolic BP (DBP) during wakefulness and sleep did not occur in the group (n = 17) without glycemic control and with SBP > 120 mmHg. Initially, 15 patients had GFR > 120 mL/min, and after six weeks, only the subgroup that achieved glycemic control (n = 7) showed a reduction of 137.2 ± 16 to 122.2 ± 25.2 mL/min (p = 0.02). At the beginning of the study, another fifteen patients presented with microalbuminuria. After six weeks, regardless of whether they achieved glycemic control or not, there was reduction in UAE, from 63.0 ± 43.1 to 24.8 ± 19.5 mg/g creatinine (p = 0.02). CONCLUSION: Thus short term glycemic control resulted in reductions of BP, GFR and the UAE in patients with DM2, which are beneficial for renal protection.

Nutritional and epidemiological aspects of patients with chronic renal failure undergoing hemodialysis from Brazil, 2010.

INTRODUCTION: The Nutrition Committee of the Brazilian Society of Nephrology (SBN) held in 2010 the first Brazilian Nutrition Census in hemodialysis patients. Multicenter data contribute to clinical development and nutritional intervention. OBJECTIVE: To describe epidemiological and nutritional aspects of hemodialysis patients. METHOD: Cross-sectional study in 36 dialysis clinics and 2,622 randomly selected participants. Socio-demographical, clinical, biochemical and anthropometric records were collected. RESULTS: 60.45% of the patients lived in the Brazilian Southeast. 13.53% came from Northeast region, while 12.81% from South, 10.33% from Midwest and 2.86% from North regions. Approximately 58% were male and 63.1% were below 60 years old. 58.5% of patients were married or in cohabitation. Around 80% of them depended on the government Unified Health System. Smoking showed a difference between gender and age. Presumptive etiologies were Hypertensive Nephrosclerosis (26.4%), Diabetic Nephropathy (24.6%), unknown/undiagnosed causes (19.9%), Glomerulopathies (13.6%) and others (11.2%). Both Hypertension and Diabetes Mellitus affect approximately 30% of patients, especially over 60 years. Body Mass Index did not differ between genders, although it differed between age groups and when used different evaluation criteria. Men and women average waist circumference were respectively 90.5 and 88.0 cm. Lipid profile did not differ between age groups, but it did between genders. Albumin values were lower in women and in patients older than 60 years. CONCLUSION: This study characterized Brazilian hemodialysis patients in 2010, and may support further studies to monitor nutrition and epidemiological transitions of the population.

Food and Nutrition Surveillance System/SISVAN: getting to know the feeding habits of infants under 24 months of age / Sistema de Vigilância Alimentar e Nutricional/SISVAN: conhecendo as práticas alimentares de crianças menores de 24 meses

The objective of the Food and Nutrition Surveillance System (SISVAN) is to monitor the food intake of individuals attended by the Brazilian Unified Health System (SUS). The objective of this research was to identify the feeding practices of children under 24 months of age who were attended at Primary Healthcare Units (UBS), using SISVAN, and to assess the relationship with maternal sociodemographic profiles. A cross-sectional study was conducted in order to evaluate 350 children using the Food Consumption Marker Form of SISVAN, and maternal demographic data to identify sociodemographic profiles by exploratory factor analysis. Of the children assessed, 41.1% were under 6 months of age and 98.7% of those between 6 and 23 months had an inadequate intake. Two sociodemographic profiles were found: Profile 1 (mothers with lower income, less education, and recipients of the 'Bolsa Família' conditional family grant program) associated with the consumption of water/tea, cow's milk and salty baby food; and Profile 2 (older mothers with many children and with a larger number of residents in the household) associated with breast milk consumption (p = 0.048). The use of SISVAN made it possible to identify that children had inadequate feeding practices, and Profile 1 appears to be a risk profile for weaning.

O Sistema de Vigilância Alimentar e Nutricional (SISVAN) objetiva monitorar as características do consumo alimentar de indivíduos atendidos pelo Sistema Único de Saúde. O objetivo deste estudo foi identificar as práticas alimentares de crianças menores de 24 meses que frequentam Unidades Básicas de Saúde (UBS), utilizando o SISVAN, e avaliar a relação com perfis sociodemográficos maternos. Estudo transversal que avaliou 350 crianças utilizando-se o Formulário de Marcadores de Consumo Alimentar do SISVAN, e dados sociodemográficos maternos para a identificação dos perfis a partir da análise fatorial exploratória. Das crianças avaliadas, 41,1% das menores de 6 meses e 98,7% daquelas entre 6 e 23 meses apresentaram consumo inadequado. Foram encontrados 2 perfis sociodemográficos: Perfil 1 (mães com menor renda, menor escolaridade e beneficiárias do Programa Bolsa Família) associado com o consumo de água/chá, leite de vaca e papa salgada; e Perfil 2 (mães com mais idade, com maior número de filhos e com maior número de residentes no domicílio) associado com o consumo de leite materno (p= 0,048). A utilização do SISVAN possibilitou identificar que as crianças apresentaram práticas alimentares inadequadas, e o Perfil 1 parece ser um perfil de risco para o desmame.

Fatores relacionados aos padrões alimentares de indivíduos com síndrome metabólica que frequentam ambulatório de nutrição em São Paulo / Dietary patterns associated factors for individuals with metabolic syndrome attending a nutrition ambulatory in São Paulo

OBJECTIVE: To identify the dietary patterns of individuals with metabolic syndrome and determine associations with sociodemographic, lifestyle, anthropometric and biochemical features. METHODS: We analyzed data of individuals with metabolic syndrome attending the nutrition outpatient clinic at a public university in São Paulo, from 2008 to 2011. We assessed food intake by 24-hour dietary recall and identified the dietary patterns using principal components analysis. Multivariate multiple linear regression models were applied to investigate possible associations between dietary patterns and the independent variables. We applied Pearson's correlations to evaluate possible associations between dietary patterns and biochemical and anthropometric variables. RESULTS: Of the 166 outpatients enrolled, 65.7% (109) were women; 63.0% (103) were adults (21-59 years) and 37.0% were elderly (60-79 years). Most people were married, sedentary and obese, with incomplete primary education, non-smoking and non- alcoholic. We identified nine dietary patterns. There was a positive association between the "traditional Brazilian" dietary pattern (rice, beans and red meat) with men and a negative association with age, and the "prudent" (whole grains, soups) with women. There was a positive correlation between the "traditional Brazilian", "compensatory" (snacks, sweeteners, light products) and "mixed" (refined grains, fruits, oils) patterns with fasting glucose, and negative correlation between the "healthy" (vegetables and oilseeds) and waist circumference. CONCLUSION: The results of this study indicate that these individuals with metabolic syndrome have dietary patterns characterized by the presence of refined foods, fats, red meat and alcohol, associated with biochemical disturbance, as impaired fasting glucose and hypertriglyceridemia

OBJETIVO: Caracterizar o padrão alimentar de indivíduos com síndrome metabólica e averiguar associações com dados sociodemográficos, estilo de vida, antropométricos e bioquímicos. MÉTODOS: Analisaram-se dados de indivíduos com síndrome metabólica em acompanhamento ambulatorial de nutrição de uma universidade pública na cidade de São Paulo, atendidos de 2008 a 2011. O consumo alimentar foi obtido por meio do Recordatório Alimentar de 24 horas. A identificação dos padrões alimentares se deu por análise fatorial por componentes principais com rotação varimax. Utilizaram-se modelos de regressão linear múltipla multivariada para verificar a relação entre os escores dos padrões alimentares e as variáveis independentes. Avaliaram-se as associações entre os padrões alimentares e variáveis bioquímicas e antropométricas por correlações de Pearson. RESULTADOS: Do total de 166 indivíduos incluídos, 65,7% (109) eram do sexo feminino; 63,0% (103) eram adultos (21 a 59 anos) e 37% eram idosos (60 a 79 anos). A maioria dos indivíduos era casada, sedentária e obesa, tinha ensino fundamental incompleto, não fumante e não etilista. Foram identificados nove padrões alimentares. Encontrou-se associação positiva entre o padrão "tradicional brasileiro" (arroz, feijão e carne vermelha) com o sexo masculino e negativa com a idade, e o padrão "prudente" (cereais integrais, sopas) com o sexo feminino. Observou-se correlação positiva entre os padrões "tradicional brasileiro", "compensatório" (lanches, adoçantes, produtos light) e "misto" (cereais refinados, frutas, óleos) com glicemia de jejum, e correlação negativa entre o padrão "saudável" (verduras e legumes e oleaginosas) e circunferência da cintura. CONCLUSÃO: Os resultados do presente estudo indicam que estes indivíduos com SM apresentam padrões alimentares caracterizados pela presença de alimentos refinados, gorduras, carnes vermelhas e bebida alcoólica, associados às alterações bioquímicas da SM, como glicemia de jejum alterada e hipertrigliceridemia

Estado nutricional e qualidade da dieta de nutrizes em amamentação exclusiva / Nutritional status and diet quality of nursing mothers on exclusive breastfeeding

OBJETIVO: Identificar o estado nutricional, o consumo alimentar e a qualidade da dieta de nutrizes em amamentação exclusiva. MÉTODOS: Estudo transversal realizado com nutrizes em aleitamento exclusivo a partir do 28º dia pós-parto. Foram utilizados instrumentos padronizados e foram avaliados o índice de massa corporal, consumo alimentar e qualidade da dieta. RESULTADOS: As nutrizes apresentaram sobrepeso, consumo energético abaixo do recomendado, porcentagens de macronutrientes adequadas exceto para proteína, que foi elevada. A dieta foi classificada como "precisando de melhorias", conforme o Índice de Alimentação Saudável. CONCLUSÃO: Os resultados mostraram que o sobrepeso associado a uma qualidade inadequada da dieta, indicou possíveis carências de micronutrientes.

OBJECTIVE: Identifying the nutritional status, dietary intake and diet quality of nursing mothers on exclusive breastfeeding. METHODS: Cross-sectional study carried out with nursing mothers on exclusive breastfeeding from day 28 postpartum. Standardized instruments were used, and body mass index, food consumption and diet quality were evaluated. RESULTS: The nursing mothers were overweight, presented energy consumption below the recommended and adequate percentage of macronutrients, except for protein, which was elevated. The diet was classified as "needs improvement" according to the Healthy Eating Index (HEI). CONCLUSION: The results show that the overweight associated with a diet of poor quality indicated possible deficiencies of micronutrients.

Validation of a quantitative food frequency questionnaire developed to under graduate students / Validacao de um questionario quantitativo de frequencia alimentar desenvolvido para universitarios

A validity test of a Food Frequency Questionnaire was carried out using 50 students of health occupation in São Paulo, Brazil. Therefore, a three day dietary record was used as reference method and variables such as energy, macronutrients and dietary fiber were analyzed. The accordance between the Food Frequency Questionnaire and average data from dietary record was tested with kappa statistics and intra-class correlation coefficients (ICC).

Better results were found for calories (ICC 0.43; 95%CI 0.17 - 0.63) and non-energy-adjusted nutrients, except dietary fiber (ICC 0.34; 95%CI 0.07 - 0.56). The percentage of individuals classified in the same category of consumption was nearly half (49.8%), while only 16% of them were classified in opposite categories. With the exception of lipids, other analyzed variables tended to be overestimated by the Food Frequency Questionnaire. The Food Frequency Questionnaire is recommended as a method of assessing food intake of university students in studies which focuson calorie estimates and also intend to classify groups into intake categories.

Efeitos do controle glicêmico obtido em curto prazo sobre a microalbuminúria e a filtração glomerular em pacientes diabéticos do tipo 2 com controle glicêmico precário / Efect of short term glycemic control on microalbuminuria and glomerular filtration rate in type 2 diabetic patients with poor glycemic control

INTRODUÇÃO: O controle intensivo da glicemia reduz significativamente o risco de desenvolvimento de complicações microvasculares, incluindo a nefropatia. OBJETIVOS: Foi avaliado o impacto do controle glicêmico, por meio do cálculo da glicemia média semanal (GMS) e variabilidade glicêmica (VG), sobre a pressão arterial (PA) nas 24 horas (MAPA), excreção urinária de albumina (EUA) e taxa de filtração glomerular (TFG). MÉTODOS: 53 pacientes com diabetes mellitus tipo 2 (DM2), dividida aleatoriamente em dois grupos para receber tratamento convencional ou intensivo. Esse último incluía visitas semanais para ajustes da medicação e aplicação de um plano educacional durante seis semanas. RESULTADOS: Observou-se controle glicêmico (GMS < 150 mg/dL e VG < 50) em 75% (n = 21) dos pacientes do grupo intervenção (GI) (n = 28) e em 24% (n = 6) do grupo convencional (GC) (n = 25) (p < 0,001). Dos 27 pacientes dos dois grupos que obtiveram controle glicêmico, 14 apresentavam inicialmente média da PA sistólica (PAS) > 120 mmHg e que se reduziu de 138,4 ± 10,1 para 127,8 ± 11,6 mmHg (p = 0,023) ao final das seis semanas. Foram observadas reduções da PAS e PA diastólica (PAD) na vigília e durante o sono, que não ocorreram no grupo (n = 17) sem controle glicêmico e PAS >120 mmHg. Inicialmente, 15 pacientes apresentavam TFG >120 mL/min, sendo que após seis semanas, apenas o subgrupo que alcançou controle glicêmico (n = 7) mostrou redução de 137,2 ± 16 para 122,2 ± 25,2 mL/min (p = 0,02). No inicio do estudo, outros quinze pacientes apresentavam microalbuminúria. Após seis semanas, independente de terem alcançado o controle glicêmico preconizado, observou-se redução da EUA de 63,0 ± 43,1 para 24,8 ± 19,5 mg/g de creatinina (p = 0,02). CONCLUSÃO: Assim, o controle glicêmico obtido em curto prazo resultou na redução da PA, da TFG e da EUA nos pacientes com DM2 que apresentavam alterações desses parâmetros, alterações benéficas no que se refere à proteção renal.

INTRODUCTION: The intensive glucose control significantly reduces the risk of microvascular complications, including nephropaty. OBJECTIVES: We assess the impact of glycemic control through calculation of weekly mean glycemia (WMG) and glycemic variability (GV) on 24 hours ambulatory blood pressure (ABPM), urinary albumin excretion (UAE) and glomerular filtration rate (GFR). METHODS: 53 patients with type 2 diabetes mellitus (DM2) were randomly divided into two groups to receive conventional or intensive treatment, which included weekly visits for medication adjustments and implementation of an educational plan for six weeks. RESULTS: We observed glycemic control (WMG < 150 mg/dL and VG < 50) in 75% (n = 21) of the patients on the intervention treatment (IT) (n = 28), and in 24% (n = 6) of the ones on the conventional treatment (CT) (n = 25) (p < 0.001). Considering patients of the two groups, 14 out of the 27 patients who achieved glycemic control showed initial mean systolic blood pressure (SBP) > 120 mmHg which was reduced from 138.4 ± 10.1 to 127.8 ± 11.6 mmHg (p = 0.023) at the end of week six. Reductions in SBP and diastolic BP (DBP) during wakefulness and sleep did not occur in the group (n = 17) without glycemic control and with SBP > 120 mmHg. Initially, 15 patients had GFR > 120 mL/min, and after six weeks, only the subgroup that achieved glycemic control (n = 7) showed a reduction of 137.2 ± 16 to 122.2 ± 25.2 mL/min (p = 0.02). At the beginning of the study, another fifteen patients presented with microalbuminuria. After six weeks, regardless of whether they achieved glycemic control or not, there was reduction in UAE, from 63.0 ± 43.1 to 24.8 ± 19.5 mg/g creatinine (p = 0.02). CONCLUSION: Thus short term glycemic control resulted in reductions of BP, GFR and the UAE in patients with DM2, which are beneficial for renal protection.

Importância da orientação nutricional e do teor de fibras da dieta no controle glicêmico de pacientes diabéticos tipo 2 sob intervenção educacional intensiva / Importance of nutritional counseling and dietary fiber content on glycemic control in type 2 diabetic patients under intensive educational intervention

OBJETIVO: Avaliar a orientação nutricional dentro de um conjunto de intervenções multidisciplinares. SUJEITOS E MÉTODOS: Quarenta e sete pacientes diabéticos tipo 2, hiperglicêmicos, tratados de forma convencional (n = 19) ou intensiva (n = 28) e avaliados pela glicemia média semanal (GMS) no início e após 6 semanas. RESULTADOS: GI reduziu o consumo de calorias (p = 0,001), carboidratos (p = 0,004), lipídios (p = 0,001) e aumentou o de fibras, enquanto o GC reduziu o consumo de fibras (p = 0,018). Controle glicêmico (GMS < 150 mg/dL) ocorreu em 75% do GI e, em 31,6% do GC (p = 0,003), houve correlação negativa entre as variações do consumo de fibras e a GMS (r =-0,309; p = 0,035). Os resultados mantiveram-se por 12 semanas. CONCLUSÃO: A intervenção educacional intensiva de curto prazo mostrou-se mais eficaz que o tratamento convencional para a obtenção do controle glicêmico. Nossos resultados ainda indicam que um consumo mais adequado de fibras na alimentação contribui para a obtenção de um melhor controle da glicemia.

OBJECTIVE: To evaluate the importance of nutritional counseling within a set of multidisciplinary interventions. SUBJECTS AND METHODS: Forty-seven patients with type 2 diabetes and hyperglycemia (A1C > 8%), treated conventionally (n = 19, GC) or intensively in six weekly visits (n = 28, GI) were analyzed. We evaluated mean weekly blood glucose (MWG) at baseline and after 6 weeks in both groups. RESULTS: GI reduced caloric (p = 0.001), carbohydrate (p = 0.004), and fat (p = 0.001) intake, and increased fiber consumption, while GC reduced fiber intake (p = 0.018). Glycemic control (MWG < 150 mg/dL) occurred in 75% of GI patients and in 31.6% of CG patients (p = 0.003), with negative correlation between changes in fiber intake and MWG values (r =-0.309; P = 0.035). Results were maintained after 12 weeks. CONCLUSION: Educational short-term intensive intervention was more effective than conventional treatment to achieve glycemic control. Our results also indicate that a more appropriate fiber content in the diet contributes for better blood glucose control in these patients.

Influence of the nutritional intervention in complementary feeding practices in infants

Avaliar a efetividade da orientação nutricional de lactentes em fase de introdução da alimentação complementar e verificar a associação das práticas alimentares com idade e escolaridade materna. Estudo de coorte histórica descritiva, avaliando-se dados secundários de 92 lactentes que realizaram pelo menos três consultas nutricionais, atendidos no Centro de Incentivo e Apoio ao Aleitamento Materno da Universidade Federal de São Paulo, no período de outubro de 2005 a março de 2010. As informações de consumo alimentar foram obtidas a partir dos Recordatórios Alimentares de 24 horas, analisados qualitativamente segundo a presença dos grupos alimentares (cereais/tubérculos, carnes/ovos, leguminosas, frutas/legumes/verduras). A orientação nutricional para a introdução da alimentação complementar foi baseada nos Dez Passos da Alimentação Saudável para Crianças Brasileiras Menores de Dois Anos, do Ministério da Saúde. Para a análise de variância em blocos não paramétrica separaram-se as crianças em dois grupos (grupo Lac A= que já recebiam alimentação complementar e grupo Lac B = que ainda não recebiam alimentação complementar). As médias e desvios-padrão do número de grupos alimentares consumidos nos momentos 0, 1 e 2 para o Lac A foram 2,3 (dp = 0,8), 2,9 (dp = 0,8) e 3,2 (dp = 0,6), respectivamente, enquanto que para o Lac B nos momentos 1 e 2 foram 2,6 (dp = 0,9) e 3,1 (dp = 0,7), respectivamente. Estatisticamente houve um aumento significativo dos grupos alimentares com o tempo para o Lac A (momentos 0 - 1 (p = 0,001), 0 - 2 (p <0, 001), 1 - 2 (p = 0,033)) e o Lac B (momentos 1 - 2 (p < 0,001)). Dentre os alimentos inadequados consumidos, aqueles que tiveram redução foram o açúcar de adição (de 22,2 por cento para 8,7 por cento) e o queijo petit suisse (de 11,1 por cento para 4,3 por cento). Não se observou relação entre a presença dos grupos alimentares com a idade e a escolaridade materna. A orientação nutricional ao longo do tempo foi efetiva, resultando na m...

Influence of the nutritional intervention in complementary feeding practices in infants / Influência da orientação nutricional nas práticas de alimentação complementar em lactentes

The objective of the present study was to evaluate the effectiveness of nutritional guidance to lactating infants undergoing the phase of complementary feeding introduction and to verify the association of food practices with age and maternal education. It is a descriptive historical cohort study in which secondary data were evaluated from 92 lactating infants who had at least 3 nutritional counselings at the "Center for Promotion and Support of Breastfeeding" from the Federal University of Sao Paulo (UNIFESP), between October 2005 and March 2010. The information of food consumption was obtained from 24 hours food records which were qualitatively analyzed according to the presence of food groups (cereals/tubers, beef/egg, legumes, fruits/vegetables). The nutritional guidance for the introduction of the complementary food was based on the 10 Steps of a Healthy Diet for Brazilian Children under 2 years of age from the Health Ministry. For the Block Non-parametric Variance Analyses children were separated in 2 groups (Lac A = those who were already on a supplementary feeding; Lac B = those who were not on a supplementary feeding). The means and standard deviations of the number of food groups consumed at moments 0,1 and 2 for Lac A were 2.3 (SD = 0.8); 2.9 (SD = 0.8) and 3.2 (SD = 0.6), respectively. For Lac B at times 1 and 2 were 2.6 (SD = 0.9) and 3.1 (SD = 0.7), respectively. There was a statistic increase of the food groups with time for Lac A (moments 0 - 1 (p = 0.001), 0 - 2 (p < 0.001), 1 - 2 (p = 0.033)) and Lac B (moments 1 - 2 (p < 0.001)). Among the inadequate offered foods, those which had reduction were sugar (from 22.2 percent to 8.7 percent) and "petit suisse" cheese (from 11.1 percent to 4.3 percent). No relation between the presence of food groups and age and maternal education was observed. The nutritional orientation over time was effective what resulted in a better quality of the complementary feeding, independent of ...(AU)

INTRODUÇÃO: O Comitê de Nutrição da Sociedade Brasileira de Nefrologia (SBN) realizou, em 2010, o primeiro Censo Brasileiro de Nutrição em pacientes em Hemodiálise. Dados multicêntricos contribuem para o desenvolvimento de condutas clínicas e intervenção nutricional. OBJETIVO: Descrever aspectos nutricionais e epidemiológicos de pacientes em hemodiálise. MÉTODO: Estudo transversal em 36 clínicas de diálise, 2.622 participantes selecionados aleatoriamente. Foram coletados: registros sociodemográficos, clínicos, bioquímicos e antropométricos. RESULTADOS: Dos pacientes, 60,45% era da região Sudeste, 13,53% Nordeste, 12,81% Sul, 10,33% Centro-Oeste e 2,86% Norte. Cerca de 58% eram homens e 63,1% tinham menos de 60 anos. Casados ou em união estável, 58,5% deles. Aproximadamente 80% dependia do Sistema Único de Saúde. O tabagismo apresentou diferença entre sexo e idade. As etiologias presuntivas foram nefroesclerose hipertensiva 26,4%, nefropatia diabética 24,6%, causas desconhecidas/não diagnosticadas 19,9%, glomerulopatias 13,6% e outros 11,2%. A hipertensão arterial e o Diabetes Mellitus acometiam aproximadamente 30% dos pacientes, principalmente aqueles acima de 60 anos. O Índice de Massa Corporal não diferiu entre sexos, embora tenha diferido entre grupos etários e quando utilizados critérios de avaliação distintos. A média de circunferência da cintura de homens e mulheres foi, respectivamente, 90,5 cm e 88,0 cm. O perfil lipídico não diferiu entre às faixas etárias, porém, houve diferenças entre sexos. Os valores de albumina estiveram menores nas mulheres e em pacientes com idade superior a 60 anos. CONCLUSÃO: O estudo caracterizou os pacientes em hemodiálise no Brasil em 2010, podendo subsidiar novos estudos para acompanhamento de transições nutricionais e epidemiológicas da população.

INTRODUCTION: The Nutrition Committee of the Brazilian Society of Nephrology (SBN) held in 2010 the first Brazilian Nutrition Census in hemodialysis patients. Multicenter data contribute to clinical development and nutritional intervention. OBJECTIVE: To describe epidemiological and nutritional aspects of hemodialysis patients. METHOD: Cross-sectional study in 36 dialysis clinics and 2,622 randomly selected participants. Socio-demographical, clinical, biochemical and anthropometric records were collected. RESULTS: 60.45% of the patients lived in the Brazilian Southeast. 13.53% came from Northeast region, while 12.81% from South, 10.33% from Midwest and 2.86% from North regions. Approximately 58% were male and 63.1% were below 60 years old. 58.5% of patients were married or in cohabitation. Around 80% of them depended on the government Unified Health System. Smoking showed a difference between gender and age. Presumptive etiologies were Hypertensive Nephrosclerosis (26.4%), Diabetic Nephropathy (24.6%), unknown/undiagnosed causes (19.9%), Glomerulopathies (13.6%) and others (11.2%). Both Hypertension and Diabetes Mellitus affect approximately 30% of patients, especially over 60 years. Body Mass Index did not differ between genders, although it differed between age groups and when used different evaluation criteria. Men and women average waist circumference were respectively 90.5 and 88.0 cm. Lipid profile did not differ between age groups, but it did between genders. Albumin values were lower in women and in patients older than 60 years. CONCLUSION: This study characterized Brazilian hemodialysis patients in 2010, and may support further studies to monitor nutrition and epidemiological transitions of the population.

Ingestão dietética de cálcio por lactantes em aleitamento materno exclusivo / Calcium dietary intake by lactating women on exclusive breastfeeding

Food intake studies on women have shown inadequacies in the consumption of nutrients, especially when calcium is concerned. Therefore, calciumin take of breast feeding women was assessed and compared to the Institute of Medicine (1997) recommendations, considering the women's nutritional requirements. Secondary data of 46 exclusively breastfeeding women were analyzed regarding food intake, collected from a validated food frequency questionnaire, and also socio-economic and anthropometric data. Statistical tests such as Student's t and ANOVA were performed,considering a 5% level of significance. As for the results, it could be observed that the mean macro nutrient consumption as well as calcium intake did not differ according to socio-economic or anthropometric variables. Besides, calcium intake was much lower (659.8mg) than the latest recommendation (1000mg), which suggests the need for health politicies that could encourage its intake by the population, particularly breastfeeding women.

Estudios de evaluación de consumo de alimentos en mujeres han mostrado inadecuación nutricional, especialmente en relación al calcio. Por esto, fue controlado el consumo de este nutriente en un grupo de mujeres durante lalactancia, a fin de determinar si está adecuado con las recomendaciones del Institute of Medicine (1997), para mujeres durante esta fase. Se utilizaron datos secundarios de 46 mujeres con lactancia materna exclusiva en relación con el consumo de alimentos, por medio del cuestionario de frecuencia de consumo de alimentos, características sociodemográficas y antropométricas. Las pruebas estadísticas utilizadas fueron Test t de Student y ANOVA, conun nivel de significancia de 5%. Se observó que el consumo promedio diario de macronutrientes y calcio no varían en función de los factores sociodemográficos y antropométricos analizados. Por otra parte, se constató que la ingestión de calcio (659,8mg) fue menor que la recomendada actualmente (1000mg), lo que sugiere la necesidad de programas que fomenten un mayor consumo de este nutriente en la población, especialmente de lactantes.

Estudos de avaliação do consumo de alimentos em mulheres têm mostrado inadequações nutricionais, especialmente no tocante ao cálcio. Desse modo, avaliou-se o consumo deste nutriente em mulheres na fase de lactação, de forma a identificar se o mesmo encontrava-se adequado às recomendações, de acordo com o Institute of Medicine (1997), considerando as necessidades nutricionais da mulher. Foram utilizados dados secundários de 46 mulheres em aleitamento materno exclusivo com relação ao consumo alimentar, a partir do questionário de frequência alimentar, características sociodemográficas e antropométricas. Foram realizados os testes estatísticos t de Student e ANOVA, com nível de significância de 5%. Observou-se que a média do consumo diário de macronutrientes e cálcio não variou de acordo com as variáveis sociodemográficas e antropométricas analisadas. Além disso, verificou-se que a ingestão de cálcio (659,8mg) foi inferior à recomendada atualmente (1000mg), o que sugere a necessidade de programas que incentivem o aumento no consumo desse nutriente entre a população, especialmente a de lactantes.

Identificação de risco cardiovascular em pacientes atendidos em abulatório de nutrição / Cardiovascular risk identification among patients treated at an outpatient nutrition clinic

Fundamentos: As doenças cardiovasculares são a principal causa de óbitos no Brasil. Cerca de 80 por cento dos casos poderiam ser evitados por meio de modificações no estilo de vida e alimentação. Objetivos: Descrever o consumo alimentar e fatores de risco cardiovascular presentes em pacientes ambulatoriais. Métodos: Estudo transversal incluindo 103 pacientes de ambos os sexos sem histórico de evento cardiovascular ou miocardiopatias. Foram utilizados dados de consumo alimentar, antropométricos, bioquímicos, de hábitos de vida e condições de saúde e o algoritmo de Framingham. Resultados: A idade média foi 51,91 +- 13,25 anos, predominando o sexo feminino. Da população estudada, 61,17 por cento eram obesos (31,91 +-5,96kg/m² adultos; 30,09+-4,87kg/m² idosos) e 92,23 por cento apresentaram aumento da circunferência da cintura, ambos mais prvalentes entre as mulheres. Na avaliação do consumo, verificou-se: dieta hipoglicídica (48,89+-9,01 por cento VCT) com alto consumo de ácidos graxos saturados...
