Objective: To estimate the prevalence of inadequate nutrient intake among adolescents and the association between socio-economic variables and nutritional status. Design: Cross-sectional study with a population-based sample. Settings: The usual nutrient intake distribution was estimated using the Iowa State University method. The Estimated Average Requirement cut-off point method was used to determine the proportion of adolescents with inadequate intake for each nutrient, according to sex, income, parental educational level and nutritional status. Subjects: Twenty-four-hour dietary recalls were applied in 525 male and female Brazilian adolescents aged 14-18 years. Results: The highest prevalence of inadequate nutrient intake was observed for vitamin E (99% in both sexes). For male and female adolescents, the prevalence of inadequate intake was: Mg, 89% and 84%; vitamin A, 78% and 71 %; vitamin C, 79% and 53%; and vitamin B(6), 21% and 33%, respectively. The prevalence of inadequate intake for niacin, thiamin, riboflavin, Se, Cu and vitamin B(12) was <15 %. Individuals in the lower income and lower parental educational level strata had the highest risk of having inadequate intake for P, riboflavin and vitamins A, B(6) and B(12). Compared with non-overweight individuals...

Introdução: O aumento alarmante da obesidade em todo mundo é um fator independente para o aumento da prevalência de doenças crônicas, como diabetes, hipertensão arterial e doença hepática gordurosa não alcoólica (DHGNA). A DHGNA engloba um amplo espectro de doença desde esteatose simples sem sinais inflamatórios, evoluindo para esteatohepatite (ENA) e até cirrose. Por ser uma patologia multifatorial sua patogênese e terapêutica ainda apresentam pontos obscuros. A resistência à insulina é um dos fatores que já foram determinados como importantes na fisiopatogênese da DHGNA e, está diretamente relacionado ao estilo de vida e hábitos alimentares. Objetivo: Avaliar a correlação entre a presença da gordura visceral e subcutânea à resistência insulínica, síndrome metabólica, medidas antropométricas e hábitos alimentares em pacientes portadores DHGNA. Resultados: Sessenta por cento dos pacientes com DHGNA apresentavam Síndrome Plurimetabólica de acordo com os critérios do ATP III. Dentre os critérios mais prevalentes da síndrome metabólica, níveis baixos HDL e circunferência de cintura (CC) aumentada ocorreram em 56%. Ao dividirmos os pacientes em grupos, os critérios se modificaram. Nos pacientes portadores de esteatose simples...

Introdução - Atualmente, vários estudos epidemiológicos têm se direcionado à população de adolescentes, devido aos seus hábitos alimentares que, quando inadequados, podem favorecer o aparecimento de diversas doenças crônicas não transmissíveis na vida adulta. A vitamina D é um nutriente de fundamental importância durante os diversos ciclos de vida, porém sua determinação é inadequada através dos questionários/recordatórios alimentares. Níveis séricos reduzidos de vitamina D estão relacionados à patogênese de diversas doenças crônicas não transmissíveis. Objetivo - Objetivou-se investigar a ingestão e os níveis séricos de vitamina D em adolescentes saudáveis, assim como quais fatores influenciam a adequação da vitamina D e a associação entre o estado nutricional da vitamina D com a adiposidade e a pressão arterial. Métodos - Trata-se de estudo transversal, onde foram avaliados 205 adolescentes, sendo 106 meninos e 99 meninas, com média de idade de 18,25 (0,07). Avaliou-se a ingestão alimentar (diário alimentar de 3 dias), o estado nutricional (peso, altura, IMC, gordura corporal e massa magra pela bioimpedância elétrica), o nível de atividade física (questionário de atividade física...

O uso de praguicidas na agricultura e pecuária pode acarretar sérios problemas à saúde dos seres humanos e dos animais. O controle da presença destas substâncias nos alimentos e no meio ambiente são um instrumento importante para minimizar o risco da exposição a estas substâncias. No Brasil, as informações sobre resíduos de praguicidas são insuficientes, especialmente quando se trata de produtos de origem animal. Um importante nutriente na dieta dos seres humanos é o ovo, principalmente na dieta infantil. De acordo com a FAO o Brasil ocupa o 7° lugar na produção de ovos com 1,72 milhões de dúzias por ano e um consumo per capita de 1,7 kg/ano (IBGE, 2003). Embora o consumo de ovos no Brasil seja um aspecto importante a maior parte da produção é exportada para outros países, principalmente, Arábia Saudita, China, Japão e Holanda. Este estudo foi desenvolvido no período de Janeiro de 2004 a Dezembro de 2006, um total de 150 amostras de ovos foram coletadas no mercado e avaliadas para a presença de resíduos de praguicidas organoclorados, organofosforados e piretróides. O método utilizado nas analises para determinar os resíduos de praguicidas nas amostras foi o DFG S19. Este método consiste em extração com solvente orgânico...

Introdução: A carga de doenças crônicas está aumentando rapidamente em todo o mundo. A proporção de ácido graxo 6/3 é um indicador qualitativo da dieta e sua elevação tem se mostrado associada a doenças crônicas na idade adulta. Em diversos países os padrões alimentares modernos apresentam proporção elevada de ácido graxo 6/3, no Brasil esse dado é desconhecido. Objetivo: Identificar os padrões de consumo alimentar da população brasileira na faixa etária de 15 a 35 anos e investigar a associação desses padrões com fatores de risco biológicos para doenças crônicas. Métodos: Foram utilizados dados do inquérito de consumo alimentar individual (POF 7) da Pesquisa Orçamento Familiares (POF) 2008 a 2009. Para estimar os padrões alimentares utilizou-se a análise de componentes principais (ACP), com rotação varimax. Para determinar o número de componentes a serem retidos na análise, consideramos aqueles com eingenvalues 1 e, para caracterizá-los, as variáveis com loadings |0,20|. Realizou-se o teste de Kaiser-Meyer-Olkin (KMO) para indicar a adequação dos dados à ACP. As associações entre os padrões alimentares (escores fatoriais) e fatores de risco para doenças crônicas, sintetizados na razão 6/3 do consumo alimentar acima de 10:1...

PUSPOSE: To evaluate food intake of patients with urinary lithiasis and idiopathic hypercalciuria (IH). MATERIALS and METHODS: Between August 2007 and June 2008, 105 patients with lithiasis were distributed into 2 groups: Group 1 (n = 55) - patients with IH (urinary calcium excretion > 250 mg in women and 300 mg in men with normal serum calcium); Group 2 (n = 50) - normocalciuria (NC) patients . Inclusion criteria were: age over 18, normal renal function (creatinine clearance = 60 mL/min), absent proteinuria and negative urinary culture. Pregnant women, patients with some intestinal pathology, chronic diarrhea or using corticoids were excluded. The protocol of metabolic investigation was based on non-consecutive collection of two 24-hour samples for dosages of: calcium, sodium, uric acid, citrate, oxalate, magnesium and urinary volume. Food intake was evaluated through the quantitative method of Dietary Register of three days. RESULTS: Urinary excretion of calcium (433.33 ± 141.92 vs. 188.93 ± 53.09), sodium (280.08 ± 100.94 vs. 200.44.93 ± 65.81), uric acid (880.63 ± 281.50 vs. 646.74 ± 182.76) and magnesium (88.78 ± 37.53 vs. 64.34 ± 31.84) was significantly higher in the IH group in comparison to the NC group (p < 0.05). As regards the nutritional composition of food intake of IH and NC groups...

Chronic ethanol intake is associated with sex hormone disturbances, and it is well known that melatonin plays a key role in regulating several reproductive processes. We report the effects of ethanol intake and melatonin treatment (at doses of 100. μg/100. g. BW/day) on sex hormones and steroid receptors in the ovaries, oviducts and uteri of ethanol-preferring rats. After 150 days of treatment, animals were euthanized, and tissue samples were harvested to evaluate androgen, estrogen, progesterone and melatonin receptor subunits (AR, ER-α and ER-β, PRA, PRB and MT1R, respectively). Melatonin decreased estradiol (E2) and increased progesterone (P4) and 6-sulfatoxymelatonin (6-STM), while an ethanol-melatonin combination reduced both P4 and E2. Ovarian AR was not influenced by either treatment, and oviduct AR was reduced after ethanol-melatonin combination. Oviduct ER-α, ER-β and uterine ER-β were down-regulated by either ethanol or melatonin. Conversely, ovarian PRA and PRB were positively regulated by ethanol and ethanol-melatonin combination, whereas PRA was down-regulated in the uterus and oviduct after ethanol consumption. MT1R was increased in ovaries and uteri of melatonin-treated rats. Ethanol and melatonin exert opposite effects on E2 and P4...

OBJECTIVES: To examine dietary intake and practices of the adult Hong Kong Chinese population to provide a basis for future public health recommendations with regard to prevention of certain chronic diseases such as cardiovascular disease, hypertension, and osteoporosis. PARTICIPANTS: Age and sex stratified random sample of the Hong Kong Chinese population aged 25 to 74 years (500 men, 510 women). METHOD: A food frequency method over a one week period was used for nutrient quantification, and a separate questionnaire was used for assessment of dietary habits. Information was obtained by interview. RESULTS: Men had higher intakes of energy and higher nutrient density of vitamin D, monounsaturated fatty acids and cholesterol, but lower nutrient density of protein, many vitamins, calcium, iron, copper, and polyunsaturated fatty acids. There was an age related decrease in energy intake and other nutrients except for vitamin C, sodium, potassium, and percentage of total calorie from carbohydrate, which all increased with age. Approximately 50% of the population had a cholesterol intake of < or = 300 mg; 60% had a fat intake < or = 30% of total energy; and 85% had a percentage of energy from saturated fats < or = 10%; criteria considered desirable for cardiovascular health. Seventy eight per cent of the population had sodium intake values in the range shown to be associated with the age related rise in blood pressure with age. Mean calcium intake was lower than the FAO/WHO recommendations. The awareness of the value of wholemeal bread and polyunsaturated fat spreads was lower in this population compared with that in Australia. There was a marked difference in types of cooking oil compared with Singaporeans...

In this exploratory study, we evaluated weight status and dietary intake patterns during painful episodes in adult patients with SCD. Specifically, we explored the relation between pain severity and body mass index (BMI), and we tested the hypothesis that dietary intake would be reduced and dietary content altered during periods of increased pain. We conducted an analysis of survey data from 62 patients involved in a longitudinal evaluation of the relationship of medical and psychosocial factors to pain. Nearly half of patients with SCD were overweight, and 20% were obese. BMI was positively related to interference associated with pain. Although BMI was not statistically associated with reported pain severity, >40% of patients reported that they perceived their pain to be affected by their weight. Less than 20% of patients reported that they perceived that their weight affected their pain. Regarding dietary patterns, the majority of patients reported eating less during episodes of pain and significantly decreasing their intake of fats and proteins. We conclude that there is a need to better understand the relation among weight, dietary patterns and pain in patients with SCD in order to provide patients with accurate education and effective treatment recommendations for managing their disease and reducing current and future risks of lifestyle and disease-related morbidities.

Obesity contributes to an increased risk for chronic diseases, including diabetes, cardiovascular diseases, and certain types of cancer. The prevalence of obesity has increased in Korea. We compared the clinical and dietary characteristics of obese adults (n = 30, 17 men and 13 women, mean age 29.9) to those with a normal weight (n = 15, 8 men and 7 women, mean age 26.5). We determined lipid profiles, fasting blood sugar (FBS), blood pressure, and serum free fatty acid (FFA). Dietary intake was estimated using a food frequency questionnaire (FFQ) and a 3-day dietary record. Exercise patterns and average alcohol intake were determined. The average body mass index was 28.3 kg/m2 in the obese and 21.2 kg/m2 in the normal weight groups. The obese group had significantly higher levels of total cholesterol, LDL cholesterol, and triglycerides, lower levels of HDL cholesterol, and higher blood pressures compared to the normal weight group. FBS was not significantly different between the two groups. The obese group had significantly more subjects with metabolic syndrome (26.7%) compared to the normal weight group (0%). Serum FFA levels tended to be higher in the obese (P = 0.087). No significant difference in caloric intake was observed between the two groups. No differences in carbohydrate...

Down syndrome (DS) is a genetic abnormality in which has its own characteristics and inherent affecting nutritional status. Individuals with Down syndrome have a predisposition to overweight by genetic factors and / or environmental. The aim of this study was to evaluate the nutritional status and its association with dietary intake, physical activity levels and demographic variables of children and adolescents with Down syndrome living in the city of Pelotas, Brazil. Participants were 41 children and adolescents aged between six and 18 years. It was observed that about 20% of children and adolescents were overweight, and physical activity is rarely practiced by the population, since more than 60% subjects were classified as having insufficient active. The findings about food consumption, point to an excessive consumption of carbohydrates and proteins, contributing to the nutritional status found. The formation of healthy eating habits and behaviors occurs in childhood, and if they give up properly can prevent of chronic illnesses that are so increasingly early, affecting children and young people.; A S??ndrome de Down (SD) ?? uma anomalia gen??tica na qual possui caracter??sticas pr??prias e inerentes que afetam o estado nutricional.

This thesis presents studies relating to effects of different macronutrients, predominantly fat and carbohydrate, on gastrointestinal motility, hormone release/suppression, appetite and energy intake in healthy subjects, and on symptom generation in patients with functional dyspepsia. The three broad areas that have been investigated in these studies are: (i) the effect of load, and duration, of small intestinal nutrient exposure on gastric motility, gastrointestinal hormone release/suppression, appetite and energy intake in healthy subjects, (ii) the dietary factors that may contribute to symptom generation in patients with functional dyspepsia, through analysis of diet diaries and acute nutrient challenges, and (iii) the effects of the herbal medication, Iberogast®, on gastric motility in healthy subjects. The ingestion of nutrients, triggers a number of gastrointestinal responses, including the modulation of antropyloroduodenal motility, gastrointestinal hormone release/suppression, and the suppression of appetite and energy intake, resulting in a slowing of gastric emptying to an average rate of 1 - 3 kcal/min, which is required for efficient nutrient digestion and absorption. Additionally, the rate at which glucose enters the small intestine influences postprandial glycaemia and incretin responses. These responses have been demonstrated in animals to be dependent on the length...

We investigated dietary intake patterns (DIP) in adolescents (14-18 year-olds) and the association with demographic and socioeconomic characteristics and lifestyle variables. This school-based survey was carried out among high school students from the city of Maringa in the state of Parana (PR), Brazil (2007). The sample included 991 students (54.5% girls) from high schools. DIPs were investigated by the frequency of weekly consumption of each food group: vegetables, fruit, rice, beans, fried food, sweet food, milk, soda, meat, eggs, alcoholic drinks. Independent variables were: demographic and socioeconomic characteristics and lifestyle variables. DIPS were identified using principal component analysis with orthogonal rotation (varimax). Three components were extracted. Component 1 (fried foods, sweets and soft drinks) was positively associated with not having breakfast for girls and dinner for boys. Moreover, component 2 (consumption of fruit and vegetables) was positively associated with having breakfast at home for boys and number of meals for girls. Component 3 (beans, eggs and meat) was positively associated with having lunch, employment and sedentary behavior level for girls. However, it was negatively associated with having lunch and dinner for boys. Adolescents who have healthier eating patterns also had other healthier behaviors regardless of gender. However...

Little is published about dietary intake of children of ethnic populations found in Hawai‘i, due to an absence of national statistics collected on Hawai‘i's population. This information is needed to focus planning of food, agriculture and health programs aimed to prevent obesity and related chronic disease and to improve health. Dietary patterns of 156 Native Hawaiian (n=110), Filipino (n=28) and White (n=18) children and their caregivers were compared using socio-demographic, annual “food season,” and 24 hour dietary recall data from a baseline survey of four lower income communities selected for an intervention program in rural Hawai‘i. Ethnic differences were found in the Healthy Eating Index (HEI) dairy component, and in calcium and vitamin C nutrient intakes among caregivers only (adjusting for food season). Whites always had higher intakes of these foods and nutrients than Filipinos or Native Hawaiians. Vitamin C intake remained significantly different among ethnic groups after further adjusting for dairy food group intake. Dietary patterns showed low intake of fruits and vegetables, fiber and dairy foods among these understudied populations.

OBJECTIVE: This systematic review sought to identify the association of dietary intake and supplementation of specific polyunsaturated fatty acids with inflammation and function in people with chronic obstructive pulmonary disease (COPD). DATA SOURCES: We searched electronic databases including PubMed, CINAHL, MEDLINE, EMBASE, The Cochrane Library, ProQuest Dissertations and Theses, Scopus, Google Scholar, Trove, and WHO International Clinical Trials Registry Platform and reference lists of retrieved articles published prior to August 2014. INCLUSION CRITERIA: We considered observational studies that evaluated dietary intake of omega-3 (eicosapentaenoic acid, docosahexaenoic acid or α-linolenic acid) and/or omega-6 fatty acids (γ-linoleic acid or arachidonic acid), and experimental studies that evaluated omega-3 fatty acid supplementation (containing predominantly one or more omega-3 fatty acids) on airway and systemic inflammatory markers and/or functional capacity outcomes in people with COPD-related diagnoses. DATA SYNTHESIS: Since statistical pooling was not possible, the findings were presented in narrative form including tables and figures to aid in data presentation when appropriate. RESULTS: One 8-week randomized controlled trial conducted in 80 COPD patients in the Netherlands showed polyunsaturated fatty acid supplementation significantly improved exercise capacity compared with the control condition [between-group difference in mean peak workload was 9.7 W (2.5-17.0; P = 0.009); and mean duration was 4.3 min (0.6-7.9; P = 0.023)]. One cross-sectional study conducted in 250 COPD patients in Spain found associations of specific dietary omega-3 fatty acids with inflammation were inconsistent. CONCLUSIONS: Limited evidence provides weak support for the use of omega-3 fatty acid supplementation for reducing chronic inflammation and some support for improving functional capacity in COPD patients. There is no consistent evidence showing that low dietary intake of specific omega-3 fatty acids worsens inflammation and/or function. More evidence is required before routinely incorporating this therapy within COPD management plans.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 License...

OBJETIVO: Avaliar o risco crônico da ingestão de pesticidas pela dieta, em compostos registrados no Brasil para uso agrícola até 1999. MÉTODOS: Foi calculada a Ingestão Diária Máxima Teórica (IDMT) para cada pesticida, utilizando limites máximos de resíduos estabelecidos pela legislação brasileira e dados de consumo alimentar. A caracterização do risco foi feita comparando-se a IDMT com as doses diárias aceitáveis (IDA) de vários países e do Codex Alimentarius. RESULTADOS: A IDTM ultrapassou a IDA (%IDA>;100) em pelo menos uma região metropolitana brasileira para 23 pesticidas. Dezesseis compostos com maior %IDA são inseticidas organofosforados, sendo o paration metílico o composto cuja ingestão mais excedeu o parâmetro toxicológico (%IDA N=9.300). O arroz, o feijão, as frutas cítricas e o tomate foram os alimentos que mais contribuíram para a ingestão. Dos compostos que apresentaram maior risco, apenas 6 foram registrados de acordo com o Decreto 98.816/90, que dispõe sobre o uso de pesticidas no País. CONCLUSÕES: Os compostos identificados como sendo de potencial risco de exposição crônica para a população brasileira, e os alimentos que mais contribuíram para a sua ingestão, devem ser priorizados pelos órgãos de saúde em programas de monitoramento de resíduos de pesticidas.

Objectives: Given the relationship between chronic periodontitis and high levels of oxidative stress, this review aims to clarify what role can played the dietary intake of different antioxidants in maintaining a healthy periodontium and in reducing chronic periodontitis risk, as well as possible use of dietary therapies based on them for this disease treatment. Methods: The database of the National Library of Medicine, Washington, DC (MEDLINE PubMed) was used and all the studies in animals and humans are on the subject of interest in English writing online available from inception of the database until May 2015 were collected. Results: Antioxidants analyzed in this regard include vitamin C, vitamin A, carotenoids and some polyphenols, and coenzyme Q; as well as minerals iron, copper and zinc that are constituents of antioxidant enzymes. Still, there is a paucity of studies with few human studies, mostly observational. Among the various antioxidants, vitamin E and polyphenols seem to have more evidence for its beneficial effect, but in general the studies are insufficient to rule out or establish what antioxidants are useful and which are not. Conclusions: Overall, the data presented indicate that dietary antioxidants are beneficial for periodontal health...

Introduction: Semi-quantitative Food Frequency Questionnaires (FFQs) analyze average food and nutrient intake over extended periods to associate habitual dietary intake with health problems and chronic diseases. A tool of this nature applicable to both women and men is not presently available in Mexico. Objective: To validate a FFQ for adult men and women. Methods: The study was conducted on 97 participants, 61% were women. Two FFQs were administered (with a one-year interval) to measure reproducibility. To assess validity, the second FFQ was compared against dietary record (DR) covering nine days. Statistical analyses included Pearson correlations and Intraclass Correlation Coefficients (ICC). The de-attenuation of the ICC resulting from intraindividual variability was controlled. The validity analysis was complemented by comparing the classification ability of FFQ to that of DR through concordance between intake categories and Bland-Altman plots. Results: Reproducibility: ICC values for food groups ranged 0.42-0.87; the range for energy and nutrients was between 0.34 and 0.82. Validity: ICC values for food groups ranged 0.35-0.84; the range for energy and nutrients was between 0.36 and 0.77. Most subjects (56.776.3%) classified in the same or adjacent quintile for energy and nutrients using both methods. Extreme misclassification was <6.3% for all items. Bland-Altman plots reveal high concordance between FFQ and DR. Conclusions: FFQ produced sufficient levels of repro-ducibility and validity to determine average daily intake over one year. These results will enable the analysis of possible associations with chronic diseases and dietary diagnoses in adult populations of men and women.
