RESUMO
OBJECTIVES: The aim of this study was to determine the usual energy and micronutrient intake distributions and compare the prevalence of insufficient/excessive micronutrient intake in Brazilian para-athletes with and without scholarship support. METHODS: The study was conducted between September 2018 and August 2019 and included 101 athletes with a disability from 13 Paralympic disciplines living in Brasília, the Federal District. Food intake was estimated from two or four non-consecutive 24-h food recalls in which para-athletes reported all food, beverages, and supplements consumed in the previous 24-h. Dietary intake analysis was performed by implementing the National Cancer Institute method. Comparisons between scholarship and non-scholarship athletes were performed using Student's t tests for parametric variables and Wilcoxon signed-rank tests for nonparametric variables. RESULTS: Mean usual energy intake was significantly lower in scholarship para-athletes (2128 ± 125 kcal/d) than in non-scholarship para-athletes (2239 ± 116 kcal/d; P < 0.001). The prevalence of inadequacy for vitamin D, calcium, vitamin A, thiamine, riboflavin, and zinc was significantly higher in scholarship than in non-scholarship para-athletes (P < 0.001). The prevalence of risk for iron deficiency was 29.5% in female para-athletes. The prevalence of micronutrient inadequacy was >10% for eight (60%) and seven (54%) micronutrients among scholarship and non-scholarship para-athletes, respectively. CONCLUSIONS: The Brazilian Federal sport scholarship assistance program in its current format is insufficient to protect athletes from micronutrient inadequacies.

BACKGROUND: The Multiple Source Method (MSM) and the National Cancer Institute (NCI) method estimate usual dietary intake from short-term dietary assessment instruments, such as 24-hour recalls. Their performance varies according to sample size and nutrients distribution. A comparison of these methods among a multiethnic youth population, for which nutrient composition and dietary variability may differ from adults, is a gap in the literature. OBJECTIVE: To compare the performance of the NCI method relative to MSM in estimating usual dietary intakes in Hispanic/Latino adolescents. DESIGN: Data derived from the cross-sectional population-based Hispanic Community Health Study/Study of Latino Youth, an ancillary study of offspring of participants in the adult Hispanic Community Health Study/Study of Latino Youth cohort. Dietary data were obtained by two 24-hour recalls. PARTICIPANTS/SETTING: One thousand four hundred fifty-three Hispanic/Latino youth (aged 8 to 16 years) living in four urban US communities (Bronx, NY; Chicago, IL; Miami, FL; and San Diego, CA) during 2012 through 2014. MAIN OUTCOME MEASURES: The NCI method and the MSM were applied to estimate usual intake of total energy, macronutrients, minerals and vitamins, added sugar, and caffeine. STATISTICAL ANALYSES: Mean, standard deviation, minimum and maximum values, coefficient of variation, variance ratio, and differences between NCI and MSM methods and the 2-day mean were estimated in several percentiles of the distribution, as well as concordance correlation coefficients and Bland-Altman plot analysis. RESULTS: The distributions of all nutrients studied were very similar between NCI and MSM. The correlation between NCI and MSM was >0.80 for all nutrients (P<0.001), except dietary cholesterol, vitamin C, and n-3 fatty acids. In individual estimations, NCI method predicted higher estimates and lower variance than the MSM. The lowest level of agreement was observed in the values at the tails of the distribution, and for nutrients with high variance ratio. CONCLUSIONS: Overall, both MSM and NCI method provided acceptable estimates of the usual intake distribution using 24-hour recall, and they better represented the usual intake compared with 2-day mean, correcting for intraindividual variability.

OBJECTIVE: To estimate the usual intake and the prevalence of inadequacy of selected nutrients in the Mexican population and the potential effect that the nutrient retention factors (NRF) could have on these estimates. Likewise, document the methodology used in the analysis of the 24 hours of the mid-way National Health and Nutrition Survey 2016 (Ensanut MC 2016). MATERIALS AND METHODS: Dietary information from the Ensanut MC 2016 was analyzed with and without the use of NRFs. RESULTS: Results. Most nutrients evaluated showed a relevant inadequacy prevalence above 10% in all age groups. Likewise, we documented that, when NRFs were not applied, estimated intakes and prevalence were significantly under-estimated in a range of 2% to 55.5%. CONCLUSIONS: We documented the relevance of the application of NRFs for adequate estimation of the prevalence of inadequate intake of selected nutrients in population studies.

BACKGROUND: In Mexico, wheat and corn flour fortification with folic acid (FA) was implemented in 2001 and mandated in 2008, but without direct enforcement. Current Mexican nutrient-content tables do not account for FA contained in bakery bread and corn masa-based foods, which are dietary staples in Mexico. OBJECTIVE: The objective of this study was to examine the impact of FA fortification of dietary staples on the proportion of the population consuming below the Estimated Average Requirement (EAR) for folate or above the Tolerable Upper Intake Level (UL) for FA. METHODS: We measured FA and folate content in dietary staples (bakery bread and tortillas) using microbial assays and MS, and we recalculated FA intake from 24-h recall dietary intake data collected in the 2012 Mexican National Health and Nutrition Survey (Encuesta Nacional de Salud y Nutrición) utilizing estimates from our food measurements, using nutrient concentrations from tortillas to approximate nutrient content of other corn masa-derived foods. The revised FA intake estimates were used to examine population-level intake of FA and dietary folate equivalent (DFE) accounting for geographic differences in FA content with statistical models. RESULTS: FA content in dietary staples was variable, whereas use of FA-fortified flour in corn masa tortillas increased with population size in place of residence. Accounting for dietary staples' FA fortification increased population estimates for FA and DFE intake, resulting in a lower proportion with intake below the EAR and a higher proportion with intake above the UL. Despite accounting for FA-fortified staple foods, 9-33% of women of childbearing age still have intake below the EAR, whereas up to 12% of younger children have intake above the UL. CONCLUSIONS: Unregulated FA fortification of dietary staples leads to unpredictable total folate intake without adequately impacting the intended target. Our findings suggest that monitoring, evaluation, and enforcement of mandatory fortification policies are needed. Without these, alternate strategies may be needed in order to reach women of childbearing age while avoiding overexposing children.

BACKGROUND: The Mexican National Health and Nutrition Survey (ENSANUT) was carried out in 2012. Information from the survey is used to design and evaluate food and nutrition policies in Mexico. OBJECTIVE: The objective of this study was to estimate the usual intake of energy and macronutrients in the Mexican population by using the ENSANUT 2012. METHODS: Twenty-four-hour recall interviews were administered to a nationally representative subsample of 10,096 individuals aged ≥1 y from the ENSANUT 2012. Usual intake distributions and the prevalence of inadequate intakes were estimated by using the Iowa State University method. Student's t tests and tests on the equality of proportions were used to compare usual intakes and prevalence of inadequacy across socioeconomic status, area (rural or urban), and region of residence (North, Center, or South). RESULTS: Energy and macronutrient intakes and indicators of dietary adequacy are presented for children (ages 1-4 y and 5-11 y), adolescents (12-19 y), and adults (≥20 y). At the national level, the estimated mean fiber intake was below the Adequate Intake for all population subgroups, suggesting inadequacies. The estimated proportion with a usual added sugars intake of >10% of total energy intake was >64% in all age groups. The proportion with a usual saturated fat intake of >10% of total energy intake was estimated to be >78% in children, >66% in adolescents, and >50% in adults. Overall, fiber intake was lower and intakes of saturated fat and added sugars were higher in urban compared with rural areas, in the North compared with South regions, and among those with high compared with low socioeconomic status (P < 0.05). CONCLUSIONS: Fiber intake is lower and added sugar and saturated fat intakes are higher than recommended for >50% of the Mexican population aged ≥1 y. These results highlight the importance of improving the diets of the overall population to reduce the risk of noncommunicable chronic diseases.

BACKGROUND: A National Health and Nutrition Survey (ENSANUT) conducted in Mexico in 1999 identified a high prevalence of inadequate mineral intakes in the population by using 24-h recall questionnaires. However, the 1999 survey did not adjust for within-person variance. The 2012 ENSANUT implemented a more up-to-date 24-h recall methodology to estimate usual intake distributions and prevalence of inadequate intakes. OBJECTIVE: We examined the distribution of usual intakes and prevalences of inadequate intakes of calcium, iron, magnesium, and zinc in the Mexican population in groups defined according to sex, rural or urban area, geographic region of residence, and socioeconomic status (SES). METHODS: We used dietary intake data obtained through the 24-h recall automated multiple-pass method for 10,886 subjects as part of ENSANUT 2012. A second measurement on a nonconsecutive day was obtained for 9% of the sample. Distributions of usual intakes of the 4 minerals were obtained by using the Iowa State University method, and the prevalence of inadequacy was estimated by using the Institute of Medicine's Estimated Average Requirement cutoff. RESULTS: Calcium inadequacy was 25.6% in children aged 1-4 y and 54.5-88.1% in subjects >5 y old. More than 45% of subjects >5 y old had an inadequate intake of iron. Less than 5% of children aged <12 y and 25-35% of subjects aged >12 y had inadequate intakes of magnesium, whereas zinc inadequacy ranged from <10% in children aged <12 y to 21.6% in men aged ≥20 y. Few differences were found between rural and urban areas, regions, and tertiles of SES. CONCLUSIONS: Intakes of calcium, iron, magnesium, and zinc are inadequate in the Mexican population, especially among adolescents and adults. These results suggest a public health concern that must be addressed.

BACKGROUND: In the past several years, the consumption of high-energy, nutrient-poor foods has increased globally. Dietary intake data collected by the National Health and Nutrition Survey (ENSANUT) 2012 provide information to assess the quality of the Mexican diet and to guide food and nutrition policy. OBJECTIVE: The aim was to describe the usual intake and the prevalence of inadequate intakes of vitamins for the overall Mexican population and by subgroups defined by sex, age, region, urban or rural areas, and socioeconomic status (SES). METHODS: ENSANUT 2012 is a cross-sectional probabilistic survey representative of the Mexican population. Dietary information was collected by using the 24-h recall automated multiple-pass method (n = 10,096) with a repeated measurement on a subsample (n = 889) to permit adjustment for intraindividual variability with the use of the Iowa State University method. Mean usual intakes and the prevalence of inadequate intakes of thiamin, riboflavin, niacin, folate, and vitamins A, D, E, C, B-6, and B-12 were calculated for children aged 1-4 y (CH1-4y), children aged 5-11 y (CH5-11y), adolescents aged 12-19 y, and adults aged ≥20 y. RESULTS: In all of the age groups, prevalences of inadequate intakes of vitamins D and E were the highest (77-99% of adults and adolescents and 53-95% of CH5-11y and CH1-4y) and those of folate and vitamin A were intermediate (47-70% of adults and adolescents, 15-23% of CH5-11y and 8-13% of CH1-4y), whereas those of thiamin, riboflavin, niacin, and vitamins B-6, B-12, and C were the lowest (0-37% of adults, 1-27% of adolescents, and 0-2.4% of CH5-11y and CH1-4y). With few exceptions, the highest prevalences of inadequate intakes for vitamins were observed in the poorest populations (rural South region and the lowest tertile of SES). CONCLUSIONS: The intake of vitamins among Mexicans is inadequate overall. Information collected by ENSANUT can help target food assistance programs and develop strategies to prevent vitamin deficiencies.

This study, conducted among students from rural areas of Pujilí Canton, Cotopaxi Province, aged 8 to 15 years, allowed to determine: 1) The individual energy requirements by levels of physical activity; 2) the levels of energy and macronutrient sufficiency and balance of diet seen in the light of International standards. It was found that more than 70 % of schoolchildren do not meet the suggested range by the Joint Expert (World Health Organization / Food and Agriculture Organization of the United Nations/ United Nations University) for energy and fat intakes, but that percentage is less than 40 % for proteins and carbohydrates. Also, the results indicate that the percentage contribution from usual macronutrient intake of schoolchildren to their estimated energy intake reach respective goal requirements established.
El presente estudio, se realizó en estudiantes de áreas rurales del Cantón Pujilí, Provincia Cotopaxi, con edades entre 8 y 15 años, el que permitió determinar: 1) Los requerimientos energéticos individuales según los niveles de actividad física realizada; 2) los niveles de suficiencia de energía y macronutrientes y de equilibrio de la dieta a la luz de los estándares internacionales. Se encontró que más del 70% de los escolares no cumplían las metas fijadas por la Consulta Mixta de Expertos (Organización Mundial de la Salud/ Organización de las Naciones Unidas para la Agricultura y la Alimentación/ Universidad de las Naciones Unidas). En relación al consumo de energía y grasas; dicho porcentaje fue inferior al 40% en el caso de las proteínas y los carbohidratos; y que el aporte porcentual de la ingesta usual de macronutrientes respecto al consumo estimado de energía se encuentra enmarcado en los respectivos requerimientos-meta establecidos.

OBJECTIVE: To compare estimates from one day with usual intake estimates to evaluate how the adjustment for within-person variability affected nutrient intake and adequacy in Mexican children. DESIGN: In order to obtain usual nutrient intakes, the National Cancer Institute's method was used to correct the first 24 h dietary recall collected in the entire sample (n 2045) with a second 24 h recall collected in a sub-sample (n 178). We computed estimates of one-day and usual intakes of total energy, fat, Fe, Zn and Na. SETTING: 2012 Mexican National Health and Nutrition Survey. SUBJECTS: A total of 2045 children were included: 0-5·9 months old (n 182), 6-11·9 months old (n 228), 12-23·9 months old (n 537) and 24-47·9 months old (n 1098). From these, 178 provided an additional dietary recall. RESULTS: Although we found small or no differences in energy intake (kJ/d and kcal/d) between one-day v. usual intake means, the prevalence of inadequate and excessive energy intake decreased somewhat when using measures of usual intake relative to one day. Mean fat intake (g/d) was not different between one-day and usual intake among children >6 months old, but the prevalence of inadequate and excessive fat intake was overestimated among toddlers and pre-schoolers when using one-day intake (P6 months. CONCLUSIONS: There was overall low variability in energy and fat intakes but higher for micronutrients. Because the usual intake distributions are narrower, the prevalence of inadequate/excessive intakes may be biased when estimating nutrient adequacy if one day of data is used.

Coffee is central to the economy of many developing countries, as well as to the world economy. However, despite the widespread consumption of coffee, there are very few available data showing the usual intake of this beverage. Surveying usual coffee intake is a way of monitoring one aspect of a population's usual dietary intake. Thus, the present study aimed to characterise the usual daily coffee intake in the Brazilian population. We used data from the National Dietary Survey collected in 2008-9 from a probabilistic sample of 34,003 Brazilians aged 10 years and older. The National Cancer Institute method was applied to obtain the usual intake based on two nonconsecutive food diaries, and descriptive statistical analyses were performed by age and sex for Brazil and its regions. The estimated average usual daily coffee intake of the Brazilian population was 163 (SE 2.8) ml. The comparison by sex showed that males had a 12% greater usual coffee intake than females. In addition, the highest intake was recorded among older males. Among the five regions surveyed, the North-East had the highest usual coffee intake (175 ml). The most common method of brewing coffee was filtered/instant coffee (71%), and the main method of sweetening beverages was with sugar (87%). In Brazil, the mean usual coffee intake corresponds to 163 ml, or 1.5 cups/d. Differences in usual coffee intake according to sex and age differed among the five Brazilian regions.

In this research article, we propose a class of models for positive and zero responses by means of a zero-augmented mixed regression model. Under this class, we are particularly interested in studying positive responses whose distribution accommodates skewness. At the same time, responses can be zero, and therefore, we justify the use of a zero-augmented mixture model. We model the mean of the positive response in a logarithmic scale and the mixture probability in a logit scale, both as a function of fixed and random effects. Moreover, the random effects link the two random components through their joint distribution and incorporate within-subject correlation because of the repeated measurements and between-subject heterogeneity. A Markov chain Monte Carlo algorithm is tailored to obtain Bayesian posterior distributions of the unknown quantities of interest, and Bayesian case-deletion influence diagnostics based on the q-divergence measure is performed. We apply the proposed method to a dataset from a 24 hour dietary recall study conducted in the city of São Paulo and present a simulation study to evaluate the performance of the proposed methods.

Objective: To present and discuss the process of the development of a Quantitative Food Frequency Questionnaire (QFFQ) aimed to 7-10 year-old children. Methods: A methodological study was performed based on the application of a Food Diary (FD) fulfilled by 85 children. Based on registered foods, the diet composition in relation to energy and macronutrients was calculated. Foods were grouped into items and the percentage of the contribution of each item to the diet in terms of calories and macronutrients were calculated. Results: The QFFQ was constructed with 92 food items, 76 were selected by Block's method and 16 were identified from other instruments from literature developed for children and adolescents. The food items were grouped in 17 food groups with 3 serving sizes and 7 categories to measure food frequency. Conclusion: Among the food items, the rice was the one that showed the biggest percentage of contribution for energy and carbohydrates. For other nutrients, the meat and the milk were the ones that contributed most to the consumption of proteins and lipids, respectively. .
Objetivo: Apresentar e discutir o processo de construção de um Questionário de Frequência Alimentar Quantitativo (QFAQ) para crianças de 7 a 10 anos. Métodos: Para a construção do QFAQ realizou-se estudo metodológico com aplicação de três Diários Alimentares (DA) a uma população de 85 escolares de 7 a 10 anos. A partir dos alimentos registrados quantificou-se a composição da dieta em energia e macronutrientes e procedeu-se ao agrupamento dos alimentos em itens, com posterior cálculo do percentual de contribuição de cada item no consumo alimentar de energia e nutrientes. Resultados: Construiu-se um QFAQ com 92 itens alimentares, sendo 76 incluídos pelo método de Block e 16 selecionados de outros instrumentos já publicados, desenvolvidos para crianças e adolescentes. Os itens alimentares foram organizados em 17 grupos de alimentos e 3 opções de porções e 7 categorias de frequência alimentar. Conclusão: Entre os itens alimentares, o arroz foi o que apresentou maior contribuição percentual para energia e carboidratos. Para os demais macronutrientes, a carne bovina e o leite integral foram os que mais contribuíram para o consumo de proteínas e lipídios, respectivamente. .
