ABSTRACT Objective To assess the effect of an educational intervention program focused on health risk conditions, based on an assessment of the hygiene and quality of food sold in school cafeterias. Methods This is a controlled, parallel, randomized, two-arm, community study. Public and private schools with cafeterias were invited to participate. This study was conducted in 27 school cafeterias in northern and northwestern Rio Grande do Sul, a state in southern Brazil. Representatives of the school communities in the intervention group received an educational program consisting of 160-hour distance training. The most relevant outcomes were the assessment of the hygienic conditions and composition of the menus sold in school cafeterias. All outcomes were analyzed as intention-to-treat and per-protocol. For the analysis of continuous data with normal distribution, an analysis of covariance and the Generalized Linear Model were used. The level of statistical significance considered was p<0.05 for a 95% CI. Results No statistically significant difference was observed between the intervention group and the control group in the studied outcomes. There was a reduction of 76.2 points in the score for hygienic handling conditions (95% CI: -205 to 357; p=0.581). Regarding menu composition, the difference between groups was 0.48% (95% CI: -2.69 to 3.64; p=0.760) for ultra-processed foods, 0.23% (95% CI: -1.13 to 1.60; p=0.740) for processed foods, and 1.02% (95% CI: -2.59 to 4.64; p=0.581) for fresh foods. Conclusion There is not enough evidence to conclude that the intervention had a positive impact on any of the outcomes studied.

ABSTRACT Objective Food and nutritional evaluation of children can support public policies to combat early overweight and obesity. This study developed and validated a quantitative food frequency questionnaire for assessing the dietary intake of children. Methods This is a cross-sectional study of the development of a food frequency questionnaire for 130 children of both genders aged 7 to 10 years old. For the food frequency questionnaire list, 81 food items were selected. The validity of the food frequency questionnaire was evaluated by comparison with 24-hour recalls and reproducibility was performed by comparing two food frequency questionnaires. Results Most of the foods with 95% relative contribution were ultra-processed, such as packaged snacks and powdered juice. In validation, correlation coefficients were found between 0.45 (p<0.000) for lipids and 0.37 (p<0.000) for carbohydrates. An adjustment for energy reduced the correlations, but there was an increase in the correlation in calcium (r=0.75) and retinol (r=0.20). In terms of reproducibility, all macronutrients and calcium showed a satisfactory intraclass correlation coefficient (>0.400) and moderate correlations [proteins (0.54; p<0.000) and lipids (0.41; p<0.000)]. Conclusion The food frequency questionnaire developed was valid and able to assess the local food consumption by children from northeastern Brazil.

ABSTRACT Objective To characterize food consumption, considering the degree of industrial food processing by public schools’ adolescents. Methods Cross-sectional study involving adolescents aged 14 to 19 years, of both genders, attending public schools in Juiz de Fora, MG. Food consumption was assessed using two 24-hour dietary recalls. Foods were classified into three groups according to the degree of industrial processing: (1) unprocessed foods or minimally processed foods, culinary ingredients and preparations based on these foods; (2) processed foods; (3) ultra-processed foods. In addition, weight and height information was collected, with subsequent calculation of body mass index/age to assess the individuals’ nutritional status according to the gender. Pearson’s chi-square, Mann-Whitney and Kruskal-Wallis tests were performed, adopting a value of p<0.05. Results The sample consisted of 804 adolescents, with a predominance of females (57.5%). In the sample, 29.9% and 26.1%, of girls and boys, respectively, were overweight. There was a difference in the daily consumption of ready-made sweet-tasting foods, being higher in females (26.2%) when compared to males (18.1%), whereas the consumption of soft drinks (one to four times a week) was 47.2% and 55.6% in girls and boys, respectively (p<0.05). Higher consumption of ultra-processed foods was observed in females (p=0.02) and processed foods in males (p=0.008). Conclusion There was a high contribution of ultra-processed foods in the diet of adolescents in public schools; a high prevalence of overweight was observed in both genders.
【摘要】目的了解公立学校青少年食品消费特征，并考虑其工业化食品加工程度。方法横断面研究纳入14至19岁的青少年，男女，在Juiz de Fora, MG公立学校就读。通过两次24小时饮食回顾来评估食物消耗。根据工业加工程度将食品分为三类:(1)未加工食品或最低限度加工食品、烹饪配料和基于这些食品的制剂;(二)加工食品;(3)超加工食品。此外，收集体重和身高信息，随后计算体重指数/年龄，根据性别评估个体的营养状况。采用Pearson卡方检验、Mann-Whitney检验和Kruskal-Wallis检验，p<0.05。结果青少年804人，以女性为主(57.5%)。在样本中，分别有29.9%的女孩和26.1%的男孩超重。在每日食用现成甜味食物方面，女性的比例(26.2%)高于男性(18.1%)，而饮用软饮料(每周一至四次)的女孩和男孩分别为47.2%和55.6% (p<0.05)。女性(p=0.02)和男性(p=0.008)对超加工食品的消费较高。结论公立学校青少年饮食中超加工食品的比例较高;在两性中均观察到较高的超重患病率。

ABSTRACT Objective To describe and compare the duration of breastfeeding of children enrolled in municipal preschools in Pelotas (RS), Brazil, in 2004 and 2018, taking into account sociodemographic and health factors. Methods Cross-sectional study, with children aged zero to six years. Data collection included interview with parents and children anthropometric assessment. Data was entered on EpiData 3.1 and analyzed on Stata 14.0. Median duration of breastfeeding was assessed according to the independent variables. Two children life tables were elaborated for the years 2004 and 2018. The statistical significance of the median analysis was based on the Wilcoxon Rank Sum test for dichotomic exposure and Kruskal Wallis test for polytomous exposure. Results A total of 1902 children were studied. In 2004, the median duration of breastfeeding was five months (IQR: 2.0;12.0) which increased one month for each weight category increase at birth. In 2018, the median was six months (IQR: 2.0;17.0) and increased two months for each weight category increase at birth. The life table showed that around 20.0% of the children in 2004 and 33% of the children in 2018 continued to be breastfed after 11 months of age. Conclusion The breastfeeding median increased in the period under review. The greater the birth weight, the longer the breastfeeding median duration.

ABSTRACT Objective To describe the nutritional profiles of children under five years of age in the state of Rondônia, comparing them with those from the Northern Region of Brazil and from Brazil. Methods This was a time series ecological study. Data were collected from the Food and Nutrition Surveillance System. The information concerned Body Mass Index by age, gender and place of residence. A time-trend analysis was performed using linear regression applying the Prais-Winsten technique and serial autocorrelation verification using the Durbin and Watson test in Stata®16.0. Results There was an annual increasing trend for the thinness, risk of overweight, overweight and obesity regardless of gender, age and location and for extreme thinness, with the exception of girls and for the age of 2 to 5 years, which revealed a stationary trend. Among boys and children of both genders under two years of age, annual growth trends were higher for non-eutrophic nutritional status when compared to the other groups. The growth rates of nutritional disorders found in the Northern region were higher than in the state of Rondônia and in Brazil. Conclusion It is necessary to review health policies aiming at the promotion and prevention of nutritional problems considering the current situation where extreme conditions such as thinness and obesity coexist, with special attention to male children under 2 years of age.

ABSTRACT Objective To investigate the relationship between calcidiol (25(OH)D3) concentrations and iron parameters in patients with chronic kidney disease. Methods This is a cross-sectional, descriptive, and quantitative study. The sample consisted of 86 adult patients of both sexes undergoing dialysis. 25(OH)D3 concentrations were determined by chemiluminescence; food consumption was assessed using 24-hour recalls, and the serum levels of hemoglobin, iron, ferritin, and transferrin saturation were assessed. Data analysis was performed using the program Stata, with a significance level of p<0.05. Results The results pointed to 25(OH)D3 concentrations compatible with sufficiency, iron levels consistent with normality, and ferritin and transferrin saturation above the reference values. The consumption of carbohydrates and lipids was higher in females. There was no relationship between the adequacy of 25(OH)D3 and the presence of anemia and iron parameters. Conclusion Considering that the mean serum levels of iron and 25(OH)D3 were adequate, it is suggested that resistance to erythropoietin and the inflammatory process may have contributed to the percentage of anemic individuals found in the study.

ABSTRACT Objective To compare the availability of healthy and unhealthy foods in families with and without elderly and oldest-old people. Methods This is an observational, cross-sectional study with secondary data from the Household Budget Survey, conducted by the Brazilian Institute of Geography and Statistics between 2017 and 2018. Families were characterized based on the oldest member: Control (without elderly and oldest-old) or with elderly and oldest-old. The sociodemographic characteristics of the families and the foods purchased by the families were obtained, according to the Nova classification (in natura, processed and ultra-processed foods, in addition to culinary ingredients). Results Families with elderly and oldest-old people had greater availability of fresh foods and fewer ultra-processed foods. In contrast, young families showed greater acquisition of all ultra-processed food items. Conclusion The unfavorable nutritional transition process with fewer in natura foods seemed to be less evident in families with higher age groups. It is concluded that the presence of the elderly and oldest-old in the family could be related to a better quality of the family diet, with a greater presence of fresh foods and a lower acquisition of ultra-processed foods.

ABSTRACT Objective This scoping review aimed to map evidence on açai supplementation combined with exercise in animal and/or human experimental studies. Methods The search considered six electronic databases and screening of relevant references. The selection process and data extraction were performed by two independent authors. The study characteristics, and AS (e.g., form, intervention time, amount ingested) and exercise (e.g., types, intensity, and duration) strategies were summarized, as well as their reported results. Results From an initial total of 342 studies identified; 11 (5 with animal and 6 with human models) were eligible. In animals, açai supplementation and exercise led to benefits in exercise tolerance and improvements in several hemodynamic parameters, as well as significant improvements in liver markers and glucose metabolism. In humans, açai supplementation indicated positive results in increasing exhaustion time to 90% of VO2max and increasing intensity at the anaerobic threshold. Conclusion We conclude that future research involving animals and humans should examine açai supplementation and exercise with (a) obesity models to test the effect of adiponectin on body composition with analysis of histological and histochemical parameters; (b) eccentric injury protocols with the incorporation of muscle quality variables to assess recovery; (c) chronic açai supplementation and strength training; (d) comparison of different forms of açai supplementation in exercise protocols.

The study characteristics, and AS (e.g., form, intervention time, amount ingested) and exercise (e.g., types, intensity, and duration) strategies were summarized, as well as their reported results. Results From an initial total of 342 studies identified; 11 (5 with animal and 6 with human models) were eligible. In animals, açai supplementation and exercise led to benefits in exercise tolerance and improvements in several hemodynamic parameters, as well as significant improvements in liver markers and glucose metabolism. In humans, açai supplementation indicated positive results in increasing exhaustion time to 90% of VO2max and increasing intensity at the anaerobic threshold. Conclusion We conclude that future research involving animals and humans should examine açai supplementation and exercise with (a) obesity models to test the effect of adiponectin on body composition with analysis of histological and histochemical parameters; (b) eccentric injury protocols with the incorporation of muscle quality variables to assess recovery; (c) chronic açai supplementation and strength training; (d) comparison of different forms of açai supplementation in exercise protocols.","PeriodicalId":21305,"journal":{"name":"Revista De Nutricao-brazilian Journal of Nutrition","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67561720","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Objective This study aimed to evaluate the perception and sensory acceptance of sweet taste by individuals who work/study on different shifts. Methods Three groups of individuals were recruited: the Control group (individuals that study during the day and do not work at night), Group 1 (individuals that study in the evening) and Group 2 (individuals that work overnight). The individuals were submitted to a detection threshold test using sucrose solutions and a sensory acceptance test using a structured hedonic scale and a Just-About-Right scale for sweet taste in blancmange. Results The detection thresholds were significantly higher for Groups 1 and 2. Individuals of Group 2 had a preference by blancmanges when having high sucrose concentrations, as well as had an ideal concentration of 10.50% sucrose against 5.95% sucrose for the Control group. Conclusion Our study shows a relationship between changes in the circadian cycle and the sensory perception and acceptance of sweet taste. More studies need to be performed to understand such relationships and their repercussions better.

ABSTRACT: Objctive: Fructose consumption has increased worldwide. Excessive fructose intake has been a risk factor for the increased metabolic syndrome disorder incidence. This study aimed to investigate the possible influence of two different exercise training methods, continuous and interval, on fructose intake. Methods: Thirty two-months-old female Wistar rats were divided into six groups: sedentary + water ; sedentary + fructose ; continuous training + water ; interval training + water ; continuous training + fructose ; interval training + fructose . Fructose was given in drinking water (10%). Continuous (40 minutes at 40% maximal speed) or interval training (28 minutes, 1 minute at 70%; 3 minutes at 35% maximal speed) sessions were carried out 3 days/week for 8 weeks. Results: Fructose consumption decreased food intake with a concomitant increase in fluid intake. Continuous and interval training did not modify food intake but progressively reduced fructose ingestion. In the 8th week, interval training + fructose and continuous training + fructose groups drank less fructose solution, 35% and 23%, respectively, than sedentary + fructose group. Conclusion: The findings indicate that both continuous and interval aerobic exercise training seem to modulate food behavior, possibly by mitigating the craving for sweetness, with interval training being more effective in reducing fructose intake than continuous exercise.
