- ItemSomente MetadadadosChronic lipoic acid treatment worsens energy imbalances in streptozotocin-induced diabetic rats(Masson Editeur, 2009-04-01) Luz, J. [UNIFESP]; Zemdegs, J. C. S. [UNIFESP]; Amaral, L. S. G. [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Aim. - Our objective was to verify the energy balance in streptozotocin-induced diabetic rats chronically treated with lipoic acid (LA).Methods. - Diabetes was induced in rats by streptozotocin and the animals divided into four groups, comprising controls and diabetic rats, with each group receiving either daily intraperitoneal LA (30 mg/kg) or a buffer solution for 30 days. Body weight, food intake and stool and urine collections were recorded daily. On day 30, animals were sacrificed and the carcasses, faeces and urine collected and processed for calorimetric analysis. Blood glucose and insulin were also determined.Results. - All parameters of energy balance were affected by diabetes. LA treatment reduced weight gain, energy gain and gross food efficiency in both control and diabetic animals. However, the LA-treated animals tended to show higher energy expenditure than non-treated animals. Body composition was also affected by diabetes: fat content was impaired by LA treatment in both control and diabetic animals. the latter also showed increased glycaemia and decreased insulinaemia, but LA had no effect on these parameters.Conclusion. - Our results indicate that chronic treatment with LA aggravates energy imbalances in diabetic animals. Moreover, our data suggest the need to reconsider the use of LA as an adjuvant in the prevention and treatment of type 1 diabetes. (C) 2008 Elsevier Masson SAS. All rights reserved.
- ItemAcesso aberto (Open Access)Densidade energetica da dieta de trabalhadores de São Paulo e fatores sociodemograficos associados*(Associação Brasileira de Saúde Coletiva, 2013-06-01) Canella, Daniela Silva; Bandoni, Daniel Henrique [UNIFESP]; Jaime, Patricia Constante; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)Objective: This paper aims at analyzing the energy density (ED) of the diet of workers from the city of São Paulo, Southeastern Brazil, and the way this is associated with socio-demographic characteristics, as well as evaluating the relationship between ED and nutrient intake. Methods: A cross-sectional study evaluated the diet of 852 workers using the 24-hour dietary recall; one recall was applied to all individuals and a second one was applied to a sub-sample in order to adjust intrapersonal variability. The ED of the diet was calculated using three methods: inclusion of all solid foods and beverages, excluding water (ED 1); inclusion of all solid foods and beverages containing at least 5 kcal/100g (ED 2); and inclusion of all solid foods, excluding all beverages (ED 3). Linear regression was used to analyze the relationship between ED and socio-demographic variables and the relationship between ED and nutrients was evaluated using Pearson coefficient correlation. Results: Considering the workers' diet, the ED values observed were 1.18 kcal/g, 1.22 kcal/g and 1.73 kcal/g for the ED 1, ED 2, ED 3 methods, respectively. In the multiple regression models, only the age variable was maintained in the final model and showed an inverse association with all ED methods. ED 3 showed an increase in energy density for non-white individuals. Of all studied nutrients, protein was the only one that was not significantly correlated with ED 3 (p = 0.899). Conclusion: The young adults studied had a higher energy-density diet, representing a priority group for nutrition interventions. Regardless of the calculation method used, there is a correlation between ED and nutrients.
- ItemAcesso aberto (Open Access)Densidade energética de refeições oferecidas em empresas inscritas no programa de alimentação do Trabalhador no município de São Paulo(Pontifícia Universidade Católica de Campinas, 2011-10-01) Canella, Daniela Silva; Bandoni, Daniel Henrique [UNIFESP]; Jaime, Patrícia Constante [UNIFESP]; Universidade de São Paulo (USP); Universidade Federal de São Paulo (UNIFESP)OBJECTIVE: This study estimated the energy density of meals served at a sample of companies registered in the Worker's Food Program and its associated factors, and assessed the relationship between energy density and nutrient supply. METHODS: This cross-sectional study encompassed 21 companies in the city of São Paulo . The energy density of the meals was calculated in two ways: inclusion of solid foods and drinks (energy density 1); inclusion of solid foods and exclusion of beverages (energy density 2). The mean energy (kcal) and food and beverage weights (g) were obtained by assessing the lunchtime menu during three consecutive days. The statistical analyses used non-parametric tests. RESULTS: The median energy density 1 was 1.10 kcal/g and for energy density 2 was 1.43 kcal/g. Some of the companies' characteristics were: 76.2% manufactured goods, the salary of the majority of the workers of 57.9% of the companies did not exceed 1562 USD per month; 85.7% of the food services were outsourced, 71.4% were supervised by a dietician and 61.9% planned the menu. The only significant difference observed was between energy density 2 and economic sector (p=0.039). Regarding macronutrient content of the meals, a positive correlation was seen between energy density 1 and the supply of protein, total fat and fibers, and between energy density 2 and the supply of total fat and saturated fat. CONCLUSION: The companies registered in the work's food program need to improve the quality of their meals. Total fat needs to be reduced. This nutrient correlates highly with high energy density.
- ItemAcesso aberto (Open Access)Dietary fiber, energy intake and nutritional status during the treatment of children with chronic constipation(Associação Brasileira de Divulgação Científica, 2003-06-01) Speridião, Patrícia da Graça Leite [UNIFESP]; Tahan, Soraia [UNIFESP]; Fagundes-Neto, Ulisses [UNIFESP]; Morais, Mauro Batista de [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)The present prospective study was carried out to determine dietary fiber and energy intake and nutritional status of children during the treatment of chronic constipation. Twenty-five patients aged 2 to 12 years with chronic constipation were submitted to clinical evaluation, assessment of dietary patterns, and anthropometry before and after 45 and 90 days of treatment. The treatment of chronic constipation included rectal disimpaction, ingestion of mineral oil and diet therapy. The standardized diet prescribed consisted of regular food without a fiber supplement and met the nutrient requirements according to the recommended daily allowance. The fiber content was 9.0 to 11.9 g for patients aged less than 6 years and 12.0 to 18.0 g for patients older than 6 years. Sixteen patients completed the 90-day follow-up and all presented clinical improvement. The anthropometric variables did not change, except midarm circumference and triceps skinfold thickness which were significantly increased. Statistically significant increases were also found in percent calorie intake adequacy in terms of recommended daily allowance (55.5 to 76.5% on day 45 and to 68.5% on day 90; P = 0.047). Percent adequacy of minimum recommended daily intake of dietary fiber (age + 5 g) increased during treatment (from 46.8 to 52.8% on day 45 and to 56.3% on day 90; P = 0.009). Food and dietary fiber intake and triceps skinfold thickness increased during follow-up. We conclude that the therapeutic program provided a good clinical outcome.
- ItemRestritoEfeito da estimulação transcraniana por corrente contínua no controle homeostático e hedônico do apetite e estados de humor em mulheres com síndrome pré-menstrual nas diferentes das fases do ciclo menstrual(Universidade Federal de São Paulo, 2023-01-05) Lima, Fernanda Santos [UNIFESP]; Gonçalves, Daniela Caetano [UNIFESP]; Panissa, Valéria Leme Gonçalves [UNIFESP]; http://lattes.cnpq.br/2597891356747368; http://lattes.cnpq.br/5735514073305152; https://lattes.cnpq.br/7216153580897329; Universidade Federal de São Paulo (UNIFESP)Objetivo: Este estudo investigou o efeito agudo da estimulação anódica transcraniana por corrente direta (a-tDCS) sobre o córtex pré-frontal dorsolateral esquerdo (DLPFC) sobre o apetite, mudanças na ingestão de energia, preferências alimentares e estado de humor nas fases lútea e folicular do ciclo menstrual em mulheres com síndrome pré-menstrual. Métodos: Dezesseis mulheres (26,5 ± 5,2 anos; 1,63 ± 0,1 m; 64,2 ± 12,8 kg; índice de massa corporal 24,0 ± 5,0 kg/m2; gordura corporal 27,6 ± 7,5%) com ciclo menstrual eumenorreico foram submetidas a a-ETCC e placebo -tDCS condições sobre suas fases folicular e lútea. No pré e pós-ETCC foram avaliados a fome e o desejo de comer algo saboroso (escala visual analógica), o perfil de estados de humor (POMS) e a preferência alimentar (Leeds Food Preference Questionnaire-BR). Os participantes registraram sua ingestão de alimentos para o resto do dia usando um registro diário. Resultados: houve um efeito principal da intervenção na fome autorreferida, desejo de comer gostoso e no gosto explícito por alimentos salgados com baixo teor de gordura, com valores mais baixos observados para a-ETCC (vs. sham-ETCC) independentemente da fase do ciclo menstrual e medição do ponto de tempo; a tensão diminuiu de pré para pós-ETCC independentemente da fase do ciclo menstrual. Houve valores mais altos na fase lútea em comparação com a fase folicular no gosto explícito por alimentos salgados com baixo teor de gordura, perturbação total do humor, depressão e estados de raiva, independentemente da condição e medição do ponto de tempo. Conclusões: a-ETCC reduziu a tensão em mulheres com síndrome pré-menstrual em ambas as fases do ciclo menstrual, enquanto as variáveis relacionadas ao apetite não foram afetadas.
- ItemSomente MetadadadosEnergy Intake in Socially Vulnerable Women Living in Brazil: Assessment of the Accuracy of Two Methods of Dietary Intake Recording Using Doubly Labeled Water(Elsevier Science Inc, 2016) Lopes Lins, Isabela Lays; Bueno, Nassib Bezerra; Grotti Clemente, Ana Paula; Pfrimer, Karina; Sawaya, Ana Lydia [UNIFESP]; de Menezes Toledo Florencio, Telma MariaBackground Diet is related to the prevention of chronic diseases, but assessing dietary intake is a complex task, especially in socially vulnerable populations. Objectives To assess the accuracy of the 24-hour food recall (24HFR) and the food frequency questionnaire (FFQ) methods in socially vulnerable women in Brazil and compare these methods against doubly labeled water (DLW). Design Cross-sectional study. Energy intake (EI) was measured using 3 24HFRs and 1 FFQ, Total energy expenditure (TEE) was measured using DLW. Cutoff points were calculated to assess underreporting and overreporting using both the difference and the ratio between the El and TEE. Participants/setting Sixty-seven socially vulnerable, nondieting adult women with stable body weight and mothers of malnourished children. Main outcome measures in kilocalories, derived from 24HFR and FFQ. Statistical analyses Repeated measures analysis of variance was used to compare El and TEE and Bland-Altman graphs were plotted to assess the agreement between these variables. Spearman correlation coefficient between the ratio of El to TEE and socioeconomic or anthropometric variables was calculated. Results Mean TEE was 2,186 kcal (95% CI 2,063 to 2,309 kcal). El obtained through 24HFR (mean=1,848.6 kcal [95% CI 1,737.5 to 1,959.7 kcal]) was significantly lower than TEE (P=0.01), and significantly lower than the EI obtained through FFQ (meth-1=2,084.5 [95% CI 1,929.0 to 2,240.0 kcal]
- ItemSomente MetadadadosGrowth of children with end-stage renal disease undergoing daily hemodialysis(Springer, 2014-03-01) Carvalho de Camargo, Maria Fernanda; Henriques, Cristina Lucia; Vieira, Simone; Komi, Shirlei; Leao, Eliseth Ribeiro; Nogueira, Paulo Cesar Koch [UNIFESP]; Hosp Samaritano São Paulo; Universidade Federal de São Paulo (UNIFESP)The aim of this report is to describe the effect of daily hemodialysis on the growth of children with end-stage renal disease (ESRD).We performed a prospective, observational study on 24 children with ESRD undergoing daily hemodialysis (DHD). the control group comprised 26 children on concurrent conventional hemodialysis (CHD), and the follow-up for both groups was 9.3 +/- 3.0 months. No patient received growth hormone (GH) therapy.At the onset of the study, the height-for-age Z-score was -2.12 +/- 1.54 in the CHD group and -2.84 +/- 2.27 in the DHD group (p = 0.313). Assuming an increase of 0.5 standard deviation scores (SDS) of the height-for-age parameter as an improvement of growth, there were 33 % of patients in the DHD group and 8 % in the CHD group (p = 0.035). the cumulative probability of gain in height for age at 12 months was 40 % in the DHD group versus 15 % in the CHD group (p = 0.047). Also, 98 % of patients in the DHD group had an adequate total caloric intake, whereas 38 % in the CHD group reached this goal (p < 0.001). No patient left the study due to intensification of the dialysis modality.Our data show that the DHD favored a 0.5 SDS height gain in a third of patients without GH treatment. Dialysis intensification was not a cause for treatment dropouts, and DHD should be considered as a treatment for selected cases, especially small children.
- ItemAcesso aberto (Open Access)O impacto da prática de corrida de aventura sobre a antropometria e o balanço energético de atletas(Universidade Federal de São Paulo (UNIFESP), 2016-03-17) Sureira, Thaiz Mattos [UNIFESP]; Amancio, Olga Maria Silverio [UNIFESP]; http://lattes.cnpq.br/8832817042816318; http://lattes.cnpq.br/2148739634320316; Universidade Federal de São Paulo (UNIFESP)The purpose of this work is to evaluate the wast and energetic intake, the anthropometrics and the handgrip strength, as well as the subjective perception of the athletes strain in an Adventure Race before, during and after the national competition circuit. Twenty-one athletes took place in this event from 24 to 48 years of age. This evaluation was held within six steps: step1 (30 days before the competition), step 2 (7 days before competion) step 3 (during the briefing), step 4 (during the competition), step 5 (at the end of the competition) and step 6 (7 days after the competition). The athlets were submitted to an anthropometric measure, handgrip strength and to energy intake and waste. Between step 3 and 5 we observe an average weight loss of 1,92kg (p<0,001), a decrease in fat percentage (an average of 0,74%), as well as within the anthropometric measures: the quantity of fat-free mass , rate of body mass and muscular area of the arm, reflecting the negative energetic balance. The evaluation of energy intake and macronutrients pointed out oscillation between the steps before and during and after the test, as much as in the hole consuming as in the relative one (g/kg of wheight). The results indicate that the Adventure Racers compete in a negative energy balance condition and the test structure directly affects the percentage of this deficit, as well as the food chosen during the competition.
- ItemAcesso aberto (Open Access)Manifestações clínicas, estado nutricional, ingestão energética, hídrica e de cálcio de indivíduos intolerantes à lactose(Universidade Federal de São Paulo, 2023-01-13) Silva, Samara Amorim da [UNIFESP]; Speridião, Patrícia da Graça Leite [UNIFESP]; http://lattes.cnpq.br/7520873457028761; http://lattes.cnpq.br/2547262551806054; Universidade Federal de São Paulo (UNIFESP)Objetivo: verificar o estado nutricional, ingestão energética, hídrica e de cálcio, manifestações clínicas, prevalência de doenças prévias, o padrão evacuatório e o uso de lactase de indivíduos com intolerância à lactose. Material e Método: trata-se de um estudo observacional e descritivo com casuística de conveniência que incluiu indivíduos de ambos os sexos, maiores de 18 anos, captados nas redes sociais (Facebook, Instagram e WhatsApp) por meio de convite. Todos os indivíduos concordaram e assinaram o Termo de Consentimento Livre e Esclarecido. Os dados foram obtidos com auxílio de um questionário estruturado, online, por meio da plataforma do Google Forms. O questionário contou com dados sociodemográficos e econômicos, alimentares e clínicos. Resultados: A pesquisa contou com 72 participantes, destes 13,9% são do sexo masculino e 86,1%, feminino. A frequência de 81,9% foi para a faixa etária entre 18 e 35 anos; o restante compreendeu a faixa etária entre 36 e 67 anos. O percentual de 57% deles, corresponde aos eutróficos e, 39% têm sobrepeso ou algum grau de obesidade. Em relação à raça, 73,6% são brancos e, 9,8% incluem os negros e amarelos. Quanto à renda, 66,7% não tem renda ou ganham até 2 salários mínimos; o restante ganha entre 2 e mais de 4 salários mínimos. Sobre o tipo de fezes, 58% têm fezes duras ou ressecadas; 15% fezes normais e 26% amolecidas. A grande maioria dos intolerantes têm doenças prévias (do trato digestório, respiratório e do sistema endócrino, entre outras). Apenas 32%, não referiu doença prévia. Entre as manifestações gastrointestinais se destacaram, diarreia (80%), flatulência (54%) e eructação (37,5%). A ingestão alimentar no sexo masculino com idade entre 19 e 30 anos foi menor para energia, cálcio e ingestão hídrica, quando comparada com a recomendação (p<0,001). Apenas as proteínas e os carboidratos se mostraram acima da recomendação, sendo a diferença significante (<0,001). Quanto ao sexo feminino, as faixas etárias entre 19 e 30 anos, 31 e 50 anos e 51 a 70 anos, também, mostraram diferenças significantes para energia, cálcio e ingestão hídrica, em relação à recomendação. O mesmo comportamento para as proteínas e carboidratos foi observado no sexo feminino. Sobre a enzima lactase, 68% dos intolerantes não fazem a reposição. Conclusões: os indivíduos intolerantes à lactose têm estado nutricional adequado, apesar da baixa ingestão energética e de não alcançaram níveis de cálcio, previstos pela recomendação vigente. Muitos deles têm doenças prévias e manifestações como diarreia, flatulência e eructação, sendo que a maioria da população observada, não faz reposição de enzima lactase. O acompanhamento nutricional e a elaboração de uma plano alimentar viável, acessível e individual é indispensável, que vise suprir as possíveis carências nutricionais e tornar o indivíduo autônomo de suas escolhas alimentares.
- ItemAcesso aberto (Open Access)Notificação imprecisa da ingestão energética na dieta de adolescentes(Sociedade Brasileira de Pediatria, 2010-10-01) Santos, Luana C. dos; Pascoal, Mariana N.; Fisberg, Mauro [UNIFESP]; Cintra, Isa de Pádua [UNIFESP]; Martini, Lígia A.; Universidade Federal de Minas Gerais Departamento de Enfermagem Materno-Infantil e Saúde Pública; Universidade Federal de São Paulo (UNIFESP); Universidade de São Paulo (USP)OBJECTIVES: To examine the prevalence of under and overreporting of energy intake in adolescents and their associated factors. METHODS: Cross-sectional study with 96 postpubertal adolescents (47 normal-weight and 49 obese), mean age of 16.6±1.3 years. Weight and height were measured, and body mass index was calculated. Body composition was assessed by dual energy X-ray absorptiometry. Dietary intake was evaluated by a 3-day dietary record. Biochemical assessment was performed (serum total cholesterol, LDL-cholesterol, HDL-cholesterol, plasma glucose, and insulin). Underreporters reported energy intake < 1.35 x basal metabolic rate (BMR), whereas overreporters reported energy intake > 2.4 x BMR. RESULTS: Energy intake misreporting (under or overreporting) was identified in 65.6% of adolescents (64.6 and 1% of under and overreporting, respectively). Obese adolescents were 5.0 times more likely to underreport energy intake (95%CI 2.0-12.7) than normal-weight participants. Underreporters showed higher rates of insufficient intake of carbohydrate (19.3 vs. 12.1%, p = 0.046) and lipids (11.3 vs. 0%, p < 0.001) than plausible reporters. Cholesterol intake was also lower in underreporters (p = 0.017). There were no significant differences in body composition and biochemical parameters in relation to misreporting. CONCLUSIONS: The results obtained demonstrated a high percentage of misreporting of energy intake among adolescents, especially among obese subjects, which suggests that energy-adjusted nutrient intake values should be employed in diet-disease risk analysis in order to contribute to a reduction in errors associated with misreporting.
- ItemSomente MetadadadosRegulation of energy intake may be impaired in nutritionally stunted children from the shantytowns of Sao Paulo, Brazil(Amer Inst Nutrition, 2000-09-01) Hoffman, Daniel Jay; Roberts, Susan B.; Verreschi, Ieda Therezinha do Nascimento [UNIFESP]; Martins, Paula Andrea [UNIFESP]; Nascimento, Celia de; Tucker, Katherine L.; Sawaya, Ana Lydia [UNIFESP]; Tufts Univ; Universidade Federal de São Paulo (UNIFESP)We tested the hypothesis that nutritionally stunted children have impaired regulation of energy intake (EI), a factor that could help explain the increased risk of obesity associated with stunting in developing countries. A 3-d residency study was conducted in 56 prepubertal boys and girls aged 8-11 y from the shantytowns of Sao Paulo, Brazil. Twenty-seven of the subjects were stunted and 29 were not stunted; weight-for-height Z-scores were not significantly different between the groups. Parents of the two groups had equivalent heights and body mass indices. Measurements were made of voluntary EI from a self-selection menu, resting energy expenditure (REE) and body composition. In addition, a 753-kJ yogurt supplement was administered at breakfast on one study day (with an equal number of children receiving the supplement on each of the 3 study days) and its effect on daily EI assessed. There was no change in EI over time in either group (P = 0.957), and no significant difference in EI between stunted and nonstunted children, even though the stunted children weighed 10% less. Energy intake per kilogram body weight was significantly higher n the stunted children (278 +/- 89 (so), vs. 333 +/- 67 kJ/kg, P < 0.05) and EI/REE was also significantly higher (1.91 +/- 0.34 vs. 1.68 +/- 0.38, P < 0.05). However, the relationship between EI and body weight was not significantly influenced by stunting (P = 0.12). There was no significant effect of the breakfast supplement on daily EI in either group although the absolute difference in EI between supplement and control days was greater in stunted than in nonstunted children (Delta EI: +460 +/- 1574 vs. -103 +/- 1916 kJ/d, P = 0.25). These data provide preliminary evidence consistent with the suggestion that stunted children tend to overeat opportunistically, but further studies are required to confirm these results in a larger study.
- ItemSomente MetadadadosWhat are the factors that influence the attainment of satisfactory energy intake in pediatric intensive care unit patients receiving enteral or parenteral nutrition?(Elsevier B.V., 2013-01-01) Menezes, Fernanda Souza de [UNIFESP]; Leite, Heitor Pons [UNIFESP]; Nogueira, Paulo Cesar Koch [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Objective: Children admitted to the intensive care unit (ICU) are at risk of inadequate energy intake. Although studies have identified factors contributing to an inadequate energy supply in critically ill children, they did not take into consideration the length of time during which patients received their estimated energy requirements after having achieved a satisfactory energy intake. This study aimed to identify factors associated with the non-attainment of estimated energy requirements and consider the time this energy intake is maintained.Methods: This was a prospective study involving 207 children hospitalized in the ICU who were receiving enteral and/or parenteral nutrition. the outcome variable studied was whether 90% of the estimated basal metabolic rate was maintained for at least half of the ICU stay (satisfactory energy intake). the exposure variables for outcome were gender, age, diagnosis, use of vasopressors, malnutrition, route of nutritional support, and Pediatric Index of Mortality and Pediatric Logistic Organ Dysfunction scores.Results: Satisfactory energy intake was attained by 20.8% of the patients, within a mean time of 5.07 +/- 2.48 d. in a multivariable analysis, a diagnosis of heart disease (odds ratio 3.62, 95% confidence interval 1.03-12.68, P = 0.045) increased the risk of insufficient energy intake, whereas malnutrition (odds ratio 0.43, 95% confidence interval 0.20-0.92, P = 0.030) and the use of parenteral nutrition (odds ratio 0.34, 95% confidence interval 0.15-0.77, P = 0.001) were protective factors against this outcome.Conclusion: A satisfactory energy intake was reached by a small proportion of patients during their ICU stay. Heart disease was an independent risk factor for the non-attainment of satisfactory energy intake, whereas malnutrition and the use of parenteral nutrition were protective factors against this outcome.
