ABSTRACT Objective This study aimed at validating the associations between the consumption of antioxidant nutrients as well as lipid alterations and cardiometabolic risks in adolescents. Methods This cross-sectional study included 327 adolescents aged 14-19 years. Sociodemographic and dietary information, anthropometric and blood pressure measurements, and biochemical data were obtained. Cardiometabolic risk was calculated by aggregating the risk factors, which were expressed as the sum of Z-scores. Poisson regression was performed to estimate the prevalence ratios. Results In boys, low intake of zinc was associated with elevated total cholesterol and triglyceride levels, whereas it was associated with low high-density lipoprotein cholesterol levels and high low-density lipoprotein cholesterol and total cholesterol levels in girls, thus indicating a cardiometabolic risk. Furthermore, low intake of copper was associated with high triglyceride levels and cardiometabolic risk in girls. The high prevalence ratios of high low-density lipoprotein cholesterol and total cholesterol levels and cardiometabolic risk were higher in those with low intake of vitamin A. Among girls, associations were also observed between lower intake of vitamin A and high triglyceride levels. Low intake of vitamin C among boys was associated with elevated high low-density lipoprotein cholesterol and triglyceride levels. Among girls, the intake of this vitamin was associated with lower low high-density lipoprotein cholesterol levels. In girls, low intake of vitamin E was associated with low low high-density lipoprotein cholesterol levels and high total cholesterol levels. Conclusion The associations between antioxidant micronutrients as well as lipid alterations and cardiometabolic risk emphasize the importance of encouraging the consumption of foods that are rich in these nutrients to modulate lipid alterations and cardiometabolic risk.

ABSTRACT Objective To evaluate the predictive ability of adiposity indicators as MetS predictors in elderly individuals. Methods Cross-sectional study enrolled in the Estratégia Saúde da Família (Family Health Strategy). Anthropometric measurements were measured. Body Mass Index, Waist-Hip Ratio, Waist-Height Ratio, Conicity Index and Body Adiposity Index were calculated. Blood was collected and resting blood pressure was measured. MetS was classified according to the harmonizing criteria. The predictive ability of anthropometric variables was evaluated using Receiver Operating Characteristic curves. Results Regarding male individuals, our research indicates that the BMI, Waist-Height Ratio and Waist Hip Ratio are better predictors and they are equivalent to each other. As for female individuals, results show that the Body Mass Index and Waist-Height Ratio are better predictors and equivalent to each other. Conclusion Waist-Height Ratio and Body Mass Index are good MetS predictors for elderly individuals, especially among men. More research in this area is important.

ABSTRACT Objective The present study aimed at investigating the association between hematological profile and serum 25-hydroxyvitamin D (25[OH]D) levels and Fokl polymorphism of the vitamin D receptor gene in individuals with Cystic Fibrosis. Methods A cross-sectional study that involved 18 men and women aged 0-25 years with Cystic Fibrosis. Socio-demographic information and the factors associated with sun exposure were obtained. Weight, height, and arm circumference were also measured. Blood sample was collected for the analysis of biochemical parameters (25[OH]D, parathyroid hormone, and calcium levels and blood count) and for the validation of the presence of FokI polymorphism in the vitamin D receptor gene. Results Among the participants, 33.33% (n=6) had vitamin D deficiency (19.60±6.180 ng/mL), and 27.8% (n=5) presented with anemia and low weight for age. In terms of genotype, 5.6% (n=1) presented with the FF genotype, 72.3% (n=13) had the Ff genotype, and 22.2% (n=4) had the ff genotype. Serum 25(OH)D levels were associated with hemoglobin (p=0.008) and hematocrit (p=0.019) levels and leukocyte count (p=0.0114). No association was observed between 25(OH)D levels and the genotypes (FF, Ff, and ff) (p=0.2451). In addition, an association was observed between FokI polymorphism and the total leukocyte count (p=0.01). Conclusion An association was observed between serum 25(OH)D levels and hemoglobin and hematocrit levels and leukocyte count in individuals with Cystic Fibrosis. Moreover, FokI polymorphism was associated with total leukocyte count.

ABSTRACT Objective To compare perception and intake of fruit and vegetables, and to identify the factors associated with misperception of intake. Methods Cross-sectional study with 3,414 participants of the Health Academy Program from Belo Horizonte (MG), Brazil. Stages of change from Transtheoretical Model were used to evaluate perception of intake, and questions adapted from national surveys were used to assess intake of fruit and vegetables as separate groups. Individuals whose intake and perception were discordant were reclassified in pseudo-maintenance (wrongly believe their intake is adequate) or non-reflective action (wrongly believe their intake is inadequate). Results Insufficient intake of fruit and vegetables and misperception of intake were observed. Pseudo-maintenance was more prevalent, given that 45.1% of individuals were reclassified in this stage regarding their vegetable intake and 22.9% regarding fruit. According to multinomial logistic regression, pseudo-maintenance of fruit intake was associated with sex, schooling, food and nutrition security, weight satisfaction, and participation in nutrition interventions; pseudo-maintenance of vegetable intake was associated with schooling and weight satisfaction. Non-reflective action was associated with age. Conclusion An important discordance between perception and intake was found, with emphasis on pseudo-maintenance of vegetable intake. Misperception was associated with different factors regarding fruit and vegetables, including sociodemographic variables, participation in nutrition interventions, and weight satisfaction. These results can contribute to the design of interventions aligned with eating behavior, aimed to empower individuals for their food choices.

ABSTRACT Objective To verify the interference of the energy intake under-reporting in the determination of the dietary patterns and nutrient intakes reported by obese women in the waiting list for bariatric surgery. Methods The study included 412 women aged 20 to 45 years with a body mass index ranging from 35 to 60kg/m2 who were on waiting list for bariatric surgery. Data from three reported food intake and physical activity, body weight, and height were used for estimating the reported energy intake, physical activity level, and resting energy expenditure. Subsequently, it was checked the biological plausibility of the reported energy intakes, classifying all participants as plausible reporters or under-reporters. Exploratory factor analysis was used to determine the participants’ dietary patterns. The Mann-Whitney test assessed the reported energy and nutrient intakes between plausible reporters and under-reporters groups. The Z-test assessed the variables of plausible reporters or under-reporters in relation to all participants of the study. Results Six dietary patterns were determined for all participants of study. After excluding information from under-reporting women, only two dietary patterns remained similar to those of all participants, while three other dietary patterns presented different conformations from food subgroups to plausible reporters. The reported energy intake did not present difference for the subgroups of fruits, leaf vegetables and vegetables. However, the energetic value reported for the other food subgroups was higher for the plausible reporters. Conclusion The under-reporting of energy intake influenced the determination of dietary patterns of obese women waiting for bariatric surgery.

ABSTRACT Objective This study aimed to analyze the implementation of the Brazilian Breastfeeding and Feeding Strategy in a Brazilian northeast capital. Methods This exploratory research uses a qualitative approach that was served with five tutors and three managers related to the strategy. The approach elaborated a graphic representation of the problem tree of the Brazilian Breastfeeding and Feeding Strategy, and subsequently, a diagram with the strategy structure was developed per the components of Logframe model. Results The study identified weaknesses on the information shown in official documents from this strategy as well as principal issues in the implementation. Using the Logframe Model, the research proposed actions to modify this reality. Conclusion The Logframe Model is an important management instrument that can contribute to strengthening and expanding the Brazilian Breastfeeding and Feeding Strategy. Therefore, it can increase breastfeeding and healthy complementary feeding rates to reduce infant mortality and morbidity.

ABSTRACT Objective Nutritional diseases such as metabolic syndrome, cardiovascular disorder, chronic inflammation or even cancer are observed in people who sustain their lifestyle by Western diet due to high calorie intake. The origin of these diseases are the degraded deoxyribonucleic acid structure. In this study, we investigated whether Western diet produced endogenous oxidative deoxyribonucleic acid damage, apoptosis or inflammation. Methods Twenty-eight male Wistar rats, aged 10-12 weeks, were divided into four groups. The rats in control group received the standard diet and the remaining rats were given one of the following three diets for four weeks: a high-fat diet containing 35% fat, a high-sucrose diet containing 69% sucrose and Western diet comprising both two types of diets. After treatment the serum 8-hydroxy-2-deoxyguanosine, poly (adenosine diphosphate ribose) polymerase-1, chitinase-3-like protein 1, soluble urokinase-type plasminogen activator receptor, Fas ligand and cytochrome c levels were measured. Results It was observed no changes in the serum soluble urokinase-type plasminogen activator receptor, Fas ligand and cytochrome c levels whereas a statistically significant increase in the serum 8-hydroxy-2-deoxyguanosine, poly (adenosine diphosphate ribose) polymerase-1 and chitinase-3-like protein 1 levels were found only in rats that were given Western diet. Conclusion The findings show that Western diet produced endogenous oxidative deoxyribonucleic acid damage, which then increased serum poly (adenosine diphosphate ribose) polymerase-1 levels, eventually leading to inflammation.

ABSTRACT Objective To evaluate the effect of protein intake on body weight gain at pregnancy. Methods A cross-sectional study was carried out with 297 women who delivered a child at the maternity ward of Municipal Hospital Leonel de Moura Brizola in Mesquita city in the state of Rio de Janeiro. Sociodemographic and anthropometric data were collected through the use of a structured questionnaire at first week after delivery. Food intake was assessed by a food frequency questionnaire. Protein intake per kilogram of body weight (g/kg per day) during pregnancy was categorized as high or low protein intake according to overall median levels. Hierarchical multiple linear regression was fitted to estimate the effect of protein intake per kg during pregnancy on weight gain. Results Women presented an average weight gain of 12.8kg (SD=6.34) and 26.8kg/m2 (SD=4.78) of Body Mass Index. Those who consumed a diet with high levels of protein content significantly presented less weight at postpartum (p<0.01) lower Early-Pregnancy Body Mass Index (p<0.01). In the hierarchical linear regression, it was found a negative association of protein intake per kg and Weight gain (b=-4.3025; IC95%=-6.0215; -2.5836; p<0.01). In the final model, all others covariates (energy, schooling, family income and gestational age) were significantly associated with the outcome (p<0.05). The additional model showed a negatively association between Early-Pregnancy Body Mass Index and weight gain (b=-0.2951; IC95%= -0.4987; -0.0915; p<0.01). Conclusion Higher levels of protein intake per kg of body weight during pregnancy were associated with lower weight gain.

ABSTRACT Objective To describe children’s physical growth (body mass and height) velocity and body composition (fat percentage and Fat Free Mass); to investigate the magnitude of interindividual differences according to age, gender and birth weight categories, as well as to examine the differences in the average trajectories of children with Low Birth Weight and Normal Weight according to international references. Methods The sample consisted of 534 children (279 boys and 255 girls, 7 to 10 years old) evaluated in the first year of study and followed for 3 years with overlap between the ages of 7 and 9 years. Physical growth and body composition measurements included: height, body mass, fat percentage (%Fat) and Fat Free Mass. Multilevel Modelling was used. Results Birth weight was not associated with physical growth and body composition markers at 7 years old or with the velocity of their changes (p>0.05). There were significant interindividual differences in the trajectories of physical growth (height and body mass; p<0.001) and body composition (%Fat and Fat Free Mass; p<0.001). In plotting on international percentile charts, the trajectories of growth and body composition were within expected values for age and gender, regardless of birth weight. Conclusion There are significant differences in the dynamics of stature growth, body mass and Fat Free Mass, and Low Birth Weight has no influence on this trajectory. In addition, values are within the expected range for age and sex.

ABSTRACT Objective To evaluate the relationship between serum retinol concentrations and subclinical infection in children from rural settlements. Methods A cross-sectional population-based study was carried out in nine rural settlements in the northeastern region of Brazil, involving 118 children aged 6 to 59 months. The relationship between serum retinol and C-Reactive Protein levels, an important marker of infectious and inflammatory processes, was investigated by multiple linear regression, controlling for demographic, socioeconomic and nutritional variables. Serum retinol and C-Reactive Protein were measured, respectively, by High Performance Liquid Chromatography and immunoturbidimetric assay in automated equipment. Results Vitamin A deficiency (retinol <0.70μmol/L) was identified in 9.3% of the children. C-Reactive Protein was the only predictor of retinol concentrations in the final regression model, causing a 0.728μmol/L reduction in retinol concentrations in the studied children (p=0.008). Conclusion Vitamin A deficiency is a problem of mild/moderate severity and measures to control infectious diseases in this population are fundamental to prevent and/or combat this problem.

ABSTRACT Objective This study estimated the combined prevalence of insufficient number of hours of sleep per day and excess body adiposity among young students. The sociodemographic and behavioral characteristics associated with this concurrent health conditions were investigated. Methods This is a cross-sectional school-based study of 975 participants aged 11-14 years in Florianópolis, Santa Catarina state, Brazil. Body adiposity was assessed based on tricipital and subscapular skinfold measurements and classified according to Lohman. The total number of hours of sleep per day was reported by the students’ parents/guardians, and it was classified as follows: as <8 hours per day and ≥8 hours per day. Data on sociodemographic characteristics, food consumption, and physical activity were collected using a self-administered questionnaire. The chi-square test and multinomial logistic regression with a 5% significance level were used to evaluate the association between the variables. Results The combined prevalence of insufficient number of hours of sleep per day and excess body adiposity was 25.1% (CI95%:20.7-29.9). The sociodemographic and behavioral factors predictive of these conditions were as follows: 13-14 year age group and household monthly income in the intermediate tertile. Conclusion The concurrent presence of insufficient sleep and excess body adiposity was found in a little more than a quarter of the students investigated. The population subgroups belonging to the 13-14 year age group and intermediate tertile of income were more likely to have concurrent insufficient number of hours of sleep per day and excess body adiposity.

Methods The protocol for food research in bereavement is presented, based on the critical review of literature and the experience with food surveys applied to bereaved people. Results The conduct protocol is divided into three moments corresponding to the meetings and the steps of approach are discussed in these care services. This research seeks to problematize this investigation, outlining the phases of coping with bereavement that involve greater adherence, from these individuals, to food surveys. Conclusion The conduct protocol guiding the investigation of eating habits of bereaved individuals provides information that allows the professional to evaluate the influence of bereavement on food in addition to allowing a greater adherence of these individuals to the survey.

ABSTRACT Objective Produce food and nutrition education videos, post these on YouTube and evaluate their reception over a two-year period. Methods Afterward bibliographic searches, sixteen different themes were developed and explored. An educational objective was defined for each video, took into account food and nutrition aspects in Brazil. The reception of the videos was evaluated using the “YouTube Analytics” tool, which allows analysis of the number of times videos were played, average playing time, and profile of the viewers. Results Sixteen videos were produced from November 2013 to July 2015. Views for each video within two years of posting were calculated individually, giving a total of 78,546 views for all videos. Most of the videos delivered their educational message before the audience lost interest. Conclusion Videos successfully reached the YouTube users and delivered the food and nutrition education messages. Therefore, this pioneering work showed YouTube as a new setting for health promotion in Brazil, paving the way for further initiatives with this platform.

ABSTRACT Objective To evaluate the intake of antioxidant nutrients by pregnant women being cared for in the Brazilian public health system and associated factors. Methods A cross-sectional study was carried out with pregnant women cared for in the public health system in the city of Maceió, Brazil, in 2014, including 385 pregnant women and their newborns, and the collection of maternal information (socioeconomic, personal, prenatal, dietary and anthropometric data), and after the babies’ birth (gestational age, birth weight and length). Food intake was assessed by two 24-hour dietary reminders per pregnant woman with subsequent adjustments by the Estimated Average Requirement method. Data were processed and Pearson’s correlation was used to evaluate associations, considering p<0.05 as significant. Results A total of 388 pregnant women with a mean age of 24.06±5.92 years were studied, with inadequate intake and high variation of the following antioxidants: vitamin A (83.2%/62.7%), vitamin C (50.5%/75.7%), vitamin E (76.5%/60.2%), Selenium (60.8%/50.3%), Copper (98.5%/42.8%) and Zinc (79.6%/43.4%), respectively. Additionally, the following associations were observed: the intake of vitamin A (p=0.02), Copper (p=0.01), and Selenium (p=0.01) with the maternal Body Mass Index; the intake of vitamin A (0.04) and Selenium (p=0.02) with the birth weight; and between vitamin A (p=0.04) with the birth length. Conclusion The low intake of antioxidant nutrients by pregnant women is a reality, being associated to the maternal Body Mass Index and the birth weight and length of the newborn.

ABSTRACT Objective To evaluate the association between diet and constipation in children between four and seven years of age. Methods A cross-sectional study with 152 children between 4 and 7 years of age residing in Viçosa, Brazil. Constipation was defined in accordance with the Rome IV diagnostic criteria. Dietary habits were evaluated based on the frequency of food intake using a food diary for three days. Dietary analysis considered foods deemed healthy and unhealthy which could be associated with constipation, as well as the children’s consumption of fruits and vegetables. The amounts of fiber and water consumed were also rated as adequate or inadequate. As part of the analyses, Student’s t-test and the chi-square test were performed with a significance level of p<0.05. Results The prevalence of constipation was 32.2%. Constipation was more common among children who did not consume fruits (p=0.020) or greens (p=0.002), as well as among children who consumed “instant” chocolate drinks (p=0.033). An association was found between the frequent consumption of fried food (p=0.020), a daily water intake lower than 600mL, and constipation (p=0.028). Conclusion Unhealthy eating habits among children, such as the lack of fruit and greens intake and the consumption of “instant” chocolate drinks and fried foods, were found to be positively correlated with constipation. The low fruit and vegetable consumption observed herein reflects the need for changes in children’s eating habits and the implementation of measures to promote the intake of healthy foods.

ABSTRACT Objective To analyze the factors associated with the consumption of extra institutional foods and the food preferences of full-time students. Methods A cross-sectional study with students from full-time municipal schools in the city of Goiânia, Brazil, from 6 to 14 years of age, both sexes and without food restrictions. The per capita family income, maternal education, nutritional status, the consumption of extra institutional foods (meals not provided by the school) in each meal and their source, and foods with higher or lower preference in school eating habits were verified. Both a Chi-Square and a Linear Trend tests were used to analyze the data. Results Three hundred and fifty nine students participated, most of them aged between 6 and 10. More than one third consumed extra institutional foods (44.0%), with the highest frequency of consumption during the mid-morning snack (34.0%). These foods mainly originated from their own households (48.7%) and one of the main items consumed was carton juice. There was an association between adolescents and mothers with higher education levels and the consumption of these items during lunch, and between students who are non-overweight and their consumption in the afternoon snack. The preferred foods were chocolate milk and bread with butter/margarine, rice and beans, passion fruit juice, and bread with cheese/requeijão and less preferably: caramelized milk and salt biscuit, beans and beets, coconut porridge and bread with cheese. Conclusion There was a high frequency of extra institutional food consumption, associated to the age group, to a higher educational level of the mother and students who are non-overweight. Foods of higher and lower preference included dairy foods and beans.

ABSTRACT Objective To investigate the association between sociodemographic factors, lifestyle, health conditions and low Handgrip Strength in older adults. Methods A cross-sectional study was conducted in a sample of 598 older adults. The Handgrip Strength (first quartile) was verified using a dynamometer. Independent variables included age group, schooling, living arrangement, paid work, alcohol consumption, smoking, leisure-time physical activity and transportation, disability in activities of daily living and instrumental activities of daily living, history of falls and probable cognitive impairment. Logistic regression analyses were performed (crude and adjusted). Results Age group, disability in instrumental activities of daily living and physical inactivity were associated with low Handgrip Strength for women. For men, there was no association. Conclusion Low Handgrip Strength was positively associated with age, disability in instrumental activities of daily living, and negatively associated with the practice of physical activity in women.

ABSTRACT Objective Develop and test recipes for a cooking skills intervention program aimed at students of a Brazilian university. Methods Culinary recipes were selected for the Nutrition and Culinary in the Kitchen program, which offers cooking classes for participants to practice and develop their cooking skills. The Nutrition and Culinary in the Kitchen program is based on the Cooking with a Chef program of the United States of America. A literature search was conducted to establish criteria for the selection and development of recipes. A decision tree was constructed to determine if Cooking With a Chef recipes were appropriate for the Nutrition and Culinary in the Kitchen program. Recipes were evaluated in the laboratory by untrained university students using an acceptance test that comprised the analysis of sensorial attributes and healthiness criteria. Results Of the 32 developed recipes, nine were based on the Cooking With a Chef program. Recipes were adapted to increase the use of fresh fruits, whole grains, and vegetables; eliminate ultra-processed foods; and take into account local food habits and seasonality of ingredients. In the first test, 53.3% (n=16) of the dishes received an acceptance score of less than 70.0% mainly because of unsatisfactory taste. Culinary recipes considered inadequate were redesigned in terms of ingredients and/or cooking methods and were retested until achieving a score of 100.0%. Conclusion Culinary recipes adapted to the Brazilian food culture and the target audience with the use of healthy ingredients and cooking techniques were considered appropriate for the Nutrition and Culinary in the Kitchen cooking skills intervention program and might increase participants’ adherence to healthy eating habits.

ABSTRACT Objective To identify potentialities and limitations for the execution of a State Plan for Food and Nutrition Security. Methods This is a qualitative research, using as a case the State Plan of Food and Nutrition Security of the state of Santa Catarina. The data were collected from an interview with eight key informants nominated by the executive secretaries of the Food and Nutrition Security Council and the Inter-Sectoral Food and the state Nutrition Security Board. The analysis took place through the Collective Subject Discourse method. Results The main potentialities were the quality of the plan and the structuring of the National System of Food and Nutrition Security in the state. The main limitations were related to the financial resources, to political interests and to the structure of the Management Chamber. Conclusion It is hoped that this study may support strategies that strengthen potentialities and minimize the limitations identified in the case studied, as well as in similar state contexts, contributing to the qualification of the Plans and consequent execution of the Food and Nutrition Security Policy.

ABSTRACT Objective To determine the centesimal composition of minerals, fatty acids and vitamin C of leaves and tubers of crem, and to discuss the nutritional potential of the T. pentaphyllum species. Methods The centesimal composition of protein, lipid, fiber, ash and carbohydrate was determined by gravimetric analysis. Mineral composition was determined by optical emission spectrometry. Vitamin C was determined by dinitrophenylhydrazine method. Fatty acids were determined by gas chromatography. The percentage of recommended dietary intake of leaves and tubers of crem was calculated for each nutrient. Results A high content of fibrous fraction (63.07g/100g), potassium (4.55g/100g), magnesium (553.64mg/100g) and sulfur (480.79mg/100g) was observed in the chemical composition of leaves. In tubers, a high carbohydrate content was observed, with 62.60g/100g of starch and 3.43g/100g of fiber, as well as high potassium (0.58g/100g), sulfur (447.14g/100), calcium (205.54g/100g) and phosphorus (530.07g/100g) levels. The vitamin C content of tubers was 78.43mg/100g and the linoleic acid content was 0.455g/100g. The intake of 100g of crem leaves may contribute with 65% of the recommended dietary intake of sulfur. The intake of 100g of crem tuber may contribute with 106% of the recommended dietary intake of sulfur and 21% of the recommended dietary intake of Vitamin C. Conclusion The chemical composition of crem (Tropaeolum pentaphyllum Lam.) tubers and leaves demonstrated an important contribution of nutrients, mainly sulfur, vitamin C and linoleic acid in its tubers, indicating a high nutritional potential of this species.
