The aim of the current study was to describe the sources of variation of energy and nutrient intake and to calculate the number of repetitions of diet measurements to estimate usual intake in adolescents from São Paulo, Brazil. Data was collected using 24-hour dietary recalls (24hR) in 273 adolescents between 2007 and 2008. Individuals completed a repeat 24hR around two months later. The sources of variation were estimated using the random effect model. Variance ratios (within-person to between-person variance ratio) and the number of repetitions of 24hR to estimate usual intake were calculated. The principal source of variation was due to within-person variance. The contribution of day of week and month of year was less than 8%. Variations ranged from 1.15 for calcium to 7.31 for vitamin E. The number of 24hR repeats required to estimate usual intake varied according to nutrient and gender, numbering 15 for males and 8 for females.; Este estudo propôs-se a descrever as fontes de variação da ingestão de energia e nutrientes e calcular o número de dias necessários para a estimativa da ingestão habitual em adolescentes do Município de São Paulo, Brasil.

Este estudo propôs-se a descrever as fontes de variação da ingestão de energia e nutrientes e calcular o número de dias necessários para a estimativa da ingestão habitual em adolescentes do Município de São Paulo, Brasil. Foi aplicado um recordatório alimentar de 24 horas (R24h) em 273 adolescentes, durante os anos de 2007 e 2008, e posteriormente cada indivíduo foi convidado a responder a outro R24h. Foram estimadas as fontes de variação da ingestão utilizando-se modelo de efeitos aleatórios. A variância intrapessoal foi o componente de variância que mais contribuiu para a variabilidade da ingestão de energia e nutrientes, ao passo que a contribuição do dia da semana e mês do ano foi pequena (< 8por cento ) para a variabilidade total da ingestão. As razões de variância variaram de 1,15 para o cálcio a 7,31 para a vitamina E. O número de R24h necessário para estimar a ingestão habitual variou de acordo com o nutriente: em torno de 15 para o sexo masculino e 8 para o feminino; The aim of the current study was to describe the sources of variation of energy and nutrient intake and to calculate the number of repetitions of diet measurements to estimate usual intake in adolescents from São Paulo, Brazil.

Dietary patterns have been related to health outcomes and morbi-mortality. Mediterranean diet indexes are correlated With adequate nutrient intake. The objective of the present study was to analyse the adequacy of nutrient intake of a posteriori defined Mediterranean (MDP) and Western (WDP) diet patterns in the Seguimiento Universidad de Navarra (SUN) cohort. A sample of 17 197 subjects participated in the study. Participants completed I 136-item validated semi-quantitative FFQ. Principal component analysis was used to define dietary patterns. Individuals were classified according to quintiles of adherence based on dietary pattern scores. Non-dietary variables, such as smoking and physical activity habits, were also taken into account. The probability approach was used to assess nutrient intake adequacy of certain vitamins (vitamins B(12), B(6), B(3), B(2), B(1), A, C, D and E) and minerals (Na, Zn, iodine, Se, folic acid, P, Mg, K, Fe and Ca). Logistic regression analysis was used to assess the adequacy of nutrient intake according to adherence to dietary patterns. WDP and MDP were defined. A higher quintile of adherence to an MDP was associated to I lower prevalence of inadequacy for the intake of Zn, iodine, vitamin E, Mg, Fe, vitamin B I...

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...

Nutritional deficiencies, especially micronutrient deficiencies, can occur in obese individuals. Surgical treatment may aggravate or cause these deficiencies, depending on the type of procedure, food intake and the use of multivitamins, minerals or other supplements. The objective of the study was to evaluate the nutrient intake of women who had undergone Roux-en-Y gastric bypass (RYGB) surgery. A cross-sectional, controlled study was conducted among 44 women after RYGB (operated-group, OG; mean years post-operation = 3.4) and a control group of 38 healthy women (non-operated group, NOG) matched by age and economic condition. The women reported their dietary intake using a 4-day record. The Dietary Reference Intakes was used as a reference. The macronutrient contributions to dietary energy intake presented an acceptable distribution for proteins and carbohydrates. Lipid intake was high among women in the OG and the NOG (43.2 and 55.3 %, respectively). In the evaluation of micronutrients, a statistically significant difference was observed between the groups for iron, zinc and vitamins B1 and B12. Both groups were at high risk for inadequate calcium intake, and the OG was at risk for inadequate zinc, iron and vitamin B1 intake. The nutrient intake of women who had undergone RYGB is very similar to that of non-operated women...

Introdução: A adolescência destaca-se como um período de elevada demanda de nutrientes. No entanto, a dieta deste grupo freqüentemente tem sido descrita como elevada em gorduras saturadas e sódio, e pobre em diversos nutrientes. Objetivo: estimar a prevalência de inadequação da ingestão de nutrientes e estimar os componentes de variância da ingestão de nutrientes entre adolescentes do município de São Paulo. Métodos: Estudo transversal, com amostra representativa da população de adolescentes do município de São Paulo, conduzido no ano de 2003. Foi coletado um recordatório de 24 horas (R24h) para cada participante (n=525), além de dados socioeconômicos e antropométricos. A medida de variabilidade da ingestão foi calculada por meio de duas replicações do R24h em uma subamostra desta população, nos anos de 2007 e 2008. A ingestão habitual foi estimada utilizando o software PC-SIDE, que utiliza o método desenvolvido pela Iowa State University. As prevalências de inadequação foram calculadas pelo método da EAR com ponto de corte, entre os sexos e entre os estratos de renda familiar per capita (RFPC), escolaridade do chefe da família, estado nutricional e etilismo, posteriormente comparados utilizando o teste de proporções. Para a estimativa da contribuição do dia da semana e do mês do ano para variância total da ingestão dos nutrientes e de energia...

Os anos 90 marcaram a expansão dos programas sociais em países em desenvolvimento, sendo que muitos desses programas consistem em aliviar a pobreza extrema e promover melhoras à vida dos indivíduos vulneráveis a tal condição. Com isso, tornou-se importante avaliar os efeitos de programas sociais a fim de verificar se o dinheiro designado pelos governos tinha o impacto esperado sobre seus beneficiados. Levando em consideração a importância dessa avaliação, diversos pesquisadores iniciaram estudos tendo como foco o principal programa federal brasileiro: o Bolsa Família. O presente estudo busca contribuir analisando os efeitos do Bolsa Família sobre o consumo de nutrientes e os índices antropométricos, utilizando dados da Pesquisa de Orçamentos Familiares (POF) de 2008-2009. Para o consumo de nutrientes, lançou-se mão de uma subamostra constituída por 25% da amostra original da POF, com pessoas com 10 anos ou mais de idade, às quais foi solicitado que registrassem todo o alimento consumido durante 24 horas em dois dias não consecutivos. A partir disso, a quantidade de alimentos da caderneta pessoal foi transformada em quantidades de nutrientes, as quais foram utilizadas nesse estudo para analisar os efeitos do PBF sobre o consumo de nutrientes. Os índices antropométricos...

Dietary patterns are a useful summary measure of diet. Few studies have examined the nutrient profiles underpinning the dietary patterns of young children. The study aim is to determine whether dietary patterns at 6 and 15 months of age are associated with nutrient intakes at 8 and 18 months, respectively. Participants were children from the Avon Longitudinal Study of Parents and Children who had complete dietary pattern and nutrient intake data (n = 725 at 6–8 months, n = 535 at 15–18 months). The association between tertiles of dietary pattern scores and nutrient intake was examined using a non-parametric test for trend. Scores on the home-made traditional pattern (6–8 months) were positively associated with median energy intake. Each dietary pattern had different associations with energy-adjusted intakes of macro- and micro-nutrients. At both times, the discretionary pattern was positively and the ready-prepared baby foods pattern was negatively associated with sodium intake. At 6–8 months, calcium and iron intakes decreased across scores on the home-made traditional and breastfeeding patterns, but increased across the ready-prepared baby food patterns. These findings highlight that dietary patterns in infants and toddlers vary in their underlying energy and nutrient composition.; Lisa G. Smithers...

Objective: To determine the plate waste, energy and selected-nutrient intake, from elderly residents living in a high-level care (HLC) and low-level care (LLC) facility. Design: Three, single, whole day assessments of plate waste, energy, and selected nutrients, using a visual rating plate waste scale. Setting: Long-term residential care establishment. Subjects: One hundred and sixty-nine (93 HLC and 76 LLC) individual daily intakes. Main findings: The mean energy wasted throughout the whole day was 17%. The energy wasted from main meals (16%) was significantly less than the energy wasted at mid-meals (22%, P=0.049). The lowest mean energy wastage occurred at breakfast (8%) compared to lunch (22%) and dinner (25%, P<0.001). The mean (s.d.) daily energy served and consumed was 8.1 (2.0) and 6.6 (2.2) MJ, respectively. There was no difference in energy served or consumed between HLC and LLC residents. On the observation day, 60% of residents consumed less than their estimated energy requirement. The mean calcium intake was 796 (346) mg, and the median (inter-quartile range) vitamin D intake was 1.78 (2.05) mug. Conclusion: On 1 day, more than half the residents surveyed were at risk of consuming an inadequate energy intake, which over-time...

This study presents the nutrient data collected from women who were being screened for premenstrual syndrome (PMS) for entry into an intervention study. Screening was by the Steiner self-rated questionnaire. One hundred and forty-four overweight women completed the screening process and eighty-eight met the criteria for PMS. All women kept 4 d diet diaries pre- and postmenstrually over two menstrual cycles. The mean energy and macronutrient intakes were compared between the pre- and postmenstrual phases. Energy and macronutrient intake was also calculated according to food categories. Goldberg's cut-off limit for the ratio of energy intake to estimated basal metabolic rate was used to exclude data that was incompatible with predicted energy requirements. The diet diaries were also used to determine the mean number of meals or snacks eaten pre- and postmenstrually. Nutrient analysis of the diet diaries of the women with PMS showed a significant increase (P<0.001) in total energy and all macronutrients premenstrually when compared to nutrient intake postmenstrually. Women who did not meet the criteria for PMS showed a significant increase in energy and fat intake (P<0.05) but not in the other macronutrients. When adjusted for energy...

Objective: To examine the relationship between sociodemographic factors (sex, age, education, occupation and region of birth) and absolute levels of energy, fat and fibre intake in adults at the national level. Design, setting and subjects: The 1983 National Dietary Survey of Adults (NDSA), covering six Australian capital cities, collected food and nutrient intake data using the 24-hour recall method, from subjects aged 25-64 years (n=6255). Results: Interactions of variables occurred, especially for males. The greatest effect on male intake of all three dietary components was a combination of age and education. For females, the main explanatory variable for fat and energy intake was age, but that for fibre was a combination of region of birth and education. Both education (alone or in combination) and region of birth (alone or in combination) had a greater effect than occupation (alone or in combination). Conclusions: Energy, fat and fibre intakes vary considerably between sociodemographic groups. Such variability must be taken into account in formulating policy and planning decisions and in assessing temporal change.

Aim: The aim of our study was to evaluate the inadequacy of voluntary energy and nutrient intake on the first day of hospital admission. Patients and methods: A cross-sectional study was carried out in two terciary care hospitals, with a probabilistic sample of 50% of in-patients. Dietary intake was evaluated by a 24-hour dietary recall, and undernutrition was screened through the Nutritional Risk Screening 2002 tool. The overall frequency of inadequate energy and nutrient intake was estimated using Dietary Reference Intakes. Results: Energy and nutrient intakes from 258 patients showed very low values for both men and women. No significant differences were found for energy and nutrient intakes across age groups (< 65 years and ≥ 65 years). When the proportion of study subjects with inadequate nutrient intakes was analysed, a high degree of inadequacy was found. The degree of inadequacy was higher for fibre, niacin, folate, vitamin B12, magnesium and zinc. No significant differences were found for energy and nutrients studied and for intakes below 1/3 of dietary recommendations from nutritionally-at-risk (n = 89) and well nourished (n = 169) patients. Conclusion: Voluntary nutrient and energy intakes in the first 24 hour of hospital admission are highly inadequate. No differences were found between undernourished and well-nourished patients or patients < 65 years and ≥ 65 years.

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.

OBJECTIVE: To describe energy and nutrient intake and adequacy percentages in Mexican adolescents included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) as well as the proportion of population at risk of dietary inadequacy. MATERIAL AND METHODS: Data were analyzed from 7-day food-frequency questionnaires for 8442 male and female adolescents 12-19 years old. Energy and nutrient adequacies as percentage of the Estimated Average Requirement were calculated and comparisons were done by region, residence area, and socioeconomic status (SES). RESULTS: Energy intake was 1903 kcal [adequacy percentage (AP=75%)] in boys, and 1 571 kcal (AP=79.2%) in girls. Intake of most nutrients (zinc, iron, vitamin C and A) was lower in subjects of low SES, living in the southern region and in rural areas. CONCLUSIONS: The rural area, the southern region, and the lower socioeconomic status show the lowest intakes and percentages of nutrient adequacy for both male and female adolescents, in particular vitamin A, folates, heme iron, zinc, and calcium.

The effects oí Moringa stenopetala leaf meal (MSLM) on nutrient intake and weight gain (WG) were evaluated. Forty unsexed Rhode Island Red chicks were randomly assigned to 4 treatment groups. The control diet (Tl) (MSLM 0%), the experimental diets contained MSML at a rate of 2% (T2), 4% (T3), and 6% (T4) of the diets (as fed basis) to replace 3%, 5.9% and 8.8% of the crude protein (CP) of the control diet. Daily feed, dry matter and CP intake of the chicks fed MSLM diets were higher (p<0.05) than those fed the control diet. Average weight gain (AWG) of birds fed MSLM diets were higher (p<0.05) than those fed the control diet. Chicks fed T4 showed higher (p<0.05) AWG than those on T2 and T3. Feed efficiency ratio (FER, g gain/g feed intake) and protein efficiency ratio (PER, g gain/g CP intake) were higher for chicks fed MSLM. MSLM elicited no deleterious effects in the birds. The results indicated that MSLM is a potential plant protein supplement and could be included to 6% in the diet of grower chicks to substitute expensive conventional protein sources.

OBJECTIVE: To estimate energy and nutrient intake and adequacy in preschool and school age Mexican children, using the National Nutrition Survey 1999 (NNS-1999). MATERIAL AND METHODS: Twenty four-h dietary recalls from pre-school (n=1 309) and school (n=2 611) children obtained from a representative sub-sample of the NNS-1999 were analyzed. Intakes and adequacies were estimated and compared across four regions, socio-economic strata, and between urban and rural areas, and indigenous vs. non-indigenous children. RESULTS: Median energy intake in pre-school children was 949 kcal and in school children 1 377 kcal, with adequacies <70% for both groups. Protein adequacy was >150% in both age groups. The North and Mexico City regions had the highest fat intake and the lowest fiber intake. Children in the South region, indigenous children, and those in the lowest socio-economic stratum had higher fiber and carbohydrate intakes and the lowest fat intake. These children also showed the highest risks of inadequacies for vitamin A, vitamin C, folate, iron, zinc and calcium. CONCLUSIONS: Mexico is experiencing a nutrition transition with internal inequalities across regions and socio-economic strata. Food policy must account for these differences in order to optimize resources directed at social programs.

The aim of the current study was to describe the sources of variation of energy and nutrient intake and to calculate the number of repetitions of diet measurements to estimate usual intake in adolescents from São Paulo, Brazil. Data was collected using 24-hour dietary recalls (24hR) in 273 adolescents between 2007 and 2008. Individuals completed a repeat 24hR around two months later. The sources of variation were estimated using the random effect model. Variance ratios (within-person to between-person variance ratio) and the number of repetitions of 24hR to estimate usual intake were calculated. The principal source of variation was due to within-person variance. The contribution of day of week and month of year was less than 8%. Variations ranged from 1.15 for calcium to 7.31 for vitamin E. The number of 24hR repeats required to estimate usual intake varied according to nutrient and gender, numbering 15 for males and 8 for females.

OBJECTIVE: To describe energy and nutrient intake and adequacy percentages in Mexican adolescents included in the Mexican National Health and Nutrition Survey 2006 (ENSANUT 2006) as well as the proportion of population at risk of dietary inadequacy. MATERIAL AND METHODS: Data were analyzed from 7-day food-frequency questionnaires for 8442 male and female adolescents 12-19 years old. Energy and nutrient adequacies as percentage of the Estimated Average Requirement were calculated and comparisons were done by region, residence area, and socioeconomic status (SES). RESULTS: Energy intake was 1903 kcal [adequacy percentage (AP=75%)] in boys, and 1 571 kcal (AP=79.2%) in girls. Intake of most nutrients (zinc, iron, vitamin C and A) was lower in subjects of low SES, living in the southern region and in rural areas. CONCLUSIONS: The rural area, the southern region, and the lower socioeconomic status show the lowest intakes and percentages of nutrient adequacy for both male and female adolescents, in particular vitamin A, folates, heme iron, zinc, and calcium.
