    Purpose: Analyze the association between school shift and the physical activities (PA) and sedentary behaviors (SB) performed in and out of the school setting among students from the second to fifth grade of elementary public school. Methods: Participants of this cross-sectional study (n=390, 50.3% girls, 9.53±1.53 years old) reported PA and SB on a web-based questionnaire (Web-CAAFE). We obtained information about shift and school grade, age and gender, and weight and height were measured for body mass index calculation and weight status classification. Results: Compared to afternoon shift students, the morning shift students reported 23% more daily PA, especially of moderate intensity (RP= 1,32; IC95%: 1,13-1,54). Students in the morning shift reported 27% more PA in school (RP= 1,27; IC95%: 1,07-1,51) and 36% more PA after school (RP= 1,36; IC95%: 1,12-1,65), at which time they also reported 62% more SB (RP= 1,62; IC95%: 1,26-2,10). There was no difference on PA and SB performed at night. Conclusion: The morning school shift was positively associated with the high amount of daily PA and, simultaneously, a slightly higher amount of CS.Objetivo: analisar a associação entre turno escolar e as atividades físicas (AF) e comportamentos sedentários (CS) desempenhados dentro e fora do ambiente escolar em escolares do segundo ao quinto ano do ensino fundamental. Método: Estudo transversal com estudantes de uma escola pública (n=390; 50,3% meninas; 9,53±1,53 anos), que relataram AF e CS através de um questionário baseado na internet (Web-CAAFE). Informações sobre turno e ano escolar, idade e gênero foram obtidas na secretaria da escola e a massa corporal e a estatura foram mensuradas para o cálculo do índice de massa corporal, utilizado para classificação do estado nutricional. Resultados: Estudantes do turno matutino relataram 23% a mais de AF diárias, sobretudo de intensidade moderada (RP= 1,32; IC95%: 1,13-1,54). Quando comparados aos estudantes do turno vespertino, os do turno matutino relataram 27% a mais de AF pela manhã (RP= 1,27; IC95%: 1,07-1,51) e 36% a mais pela tarde (RP= 1,36; IC95%: 1,12-1,65), quando também relataram 62% a mais de CS (RP= 1,62; IC95%: 1,26-2,10). Não houve diferença nas AF e CS desempenhados à noite. Conclusão: O turno escolar matutino mostrou-se positivamente associado à maior quantidade de AF diárias entre os estudantes, ainda que eles tenham relatado simultaneamente maior quantidade de CS

    Este relato descreve a criação e consolidação da linha de pesquisa “Consumo alimentar, atividade física e comportamento sedentário de crianças e adolescentes”, no Núcleo de Estudos e Pesquisas em Atividade Física e Saúde (NEPAFIS), em uma Universidade Estadual Baiana. A realização do estudo de validação do Web-CAAFE, uma ferramenta online de vigilância em saúde de escolares, foi o ponto de partida para a criação da linha de pesquisa e sua consolidação ocorreu, em 2019, após realização de uma pesquisa de base escolar, utilizando o Web-CAAFE para avaliar consumo alimentar, atividade física, comportamentos sedentários, modos de deslocamento para/da escola e o estado nutricional de uma amostra de 2.654 estudantes do segundo ao quinto ano do Ensino Fundamental de Feira de Santana, Bahia. Os achados mostraram que: 1) há sobreposição de comportamentos saudáveis e não saudáveis entre os participantes; 2) há marcantes diferenças de gênero nas atividades físicas; 3) um número expressivo de estudantes estava com sobrepeso/obesidade; 4) o uso de telas se associa ao consumo de alimentos não saudáveis; 5) a infraestrutura escolar para a prática de esportes, atividades físicas e de lazer, assim como a participação nas aulas de educação física, influenciam as atividades físicas e os comportamentos sedentários dos estudantes. Atualmente, a linha de pesquisa desenvolve estudo com comunidades Quilombolas da zona rural do município, cujos resultados esperados podem possibilitar conhecer os comportamentos de movimento dos estudantes dessas comunidades, estado nutricional, consumo alimentar e a adequação do cardápio da alimentação escolar às especificidades culturais das comunidades.This report describes rise and consolidation of the research line “Food consumption, physical activity and sedentary behavior of children and adolescents”, at the Núcleo de Estudos e Pesquisas em Atividade Física e Saúde (NEPAFIS), in a State University from Bahia. The validation study of the Web-CAAFE, an online health surveillance tool for schoolchildren, was the starting point for the rise of the line of research that was consolidated in 2019, after carrying out a school-based survey, using the Web-CAAFE to assess food consumption, physical activity, sedentary behaviors, commuting to/from school and the weight status of 2,654 students from the second to the fifth year of Elementary School in Feira de Santana, Bahia. The findings showed that: 1) there is an overlap of healthy and unhealthy behaviors among the participants; 2) there are marked gender differences in physical activities; 3) a significant number of students were overweight/obese; 4) the use of screens is associated with the consumption of unhealthy foods; 5) school infrastructure for sports, physical and leisure-time physical activities, as well as participation in physical education classes, influence students' physical activities and sedentary behaviors. Currently, the line of research is developing a study with Quilombola communities in the rural areas of Feira de Santana, and the expected results will make it possible to know the movement behaviors of students in these communities, the weight status, food consumption and the adequacy of the school meal menu to the cultural specificities of Quilombola communities.Este informe describe la creación y consolidación de la línea de investigación “Consumo de alimentos, actividad física y comportamiento sedentario de niños y adolescentes”, en el Centro de Estudios e Investigaciones en Actividad Física y Salud (NEPAFIS), de una Universidad del Nordeste de Brasil.

    Implementation of a Brazilian Cardioprotective Nutritional (BALANCE) Program for improvement on quality of diet and secondary prevention of cardiovascular events: A randomized, multicenter trial

    Get PDF
    Background: Appropriate dietary recommendations represent a key part of secondary prevention in cardiovascular disease (CVD). We evaluated the effectiveness of the implementation of a nutritional program on quality of diet, cardiovascular events, and death in patients with established CVD. Methods: In this open-label, multicenter trial conducted in 35 sites in Brazil, we randomly assigned (1:1) patients aged 45 years or older to receive either the BALANCE Program (experimental group) or conventional nutrition advice (control group). The BALANCE Program included a unique nutritional education strategy to implement recommendations from guidelines, adapted to the use of affordable and regional foods. Adherence to diet was evaluated by the modified Alternative Healthy Eating Index. The primary end point was a composite of all-cause mortality, cardiovascular death, cardiac arrest, myocardial infarction, stroke, myocardial revascularization, amputation, or hospitalization for unstable angina. Secondary end points included biochemical and anthropometric data, and blood pressure levels. Results: From March 5, 2013, to Abril 7, 2015, a total of 2534 eligible patients were randomly assigned to either the BALANCE Program group (n = 1,266) or the control group (n = 1,268) and were followed up for a median of 3.5 years. In total, 235 (9.3%) participants had been lost to follow-up. After 3 years of follow-up, mean modified Alternative Healthy Eating Index (scale 0-70) was only slightly higher in the BALANCE group versus the control group (26.2 ± 8.4 vs 24.7 ± 8.6, P <.01), mainly due to a 0.5-serving/d greater intake of fruits and of vegetables in the BALANCE group. Primary end point events occurred in 236 participants (18.8%) in the BALANCE group and in 207 participants (16.4%) in the control group (hazard ratio, 1.15; 95% CI 0.95-1.38; P =.15). Secondary end points did not differ between groups after follow-up. Conclusions: The BALANCE Program only slightly improved adherence to a healthy diet in patients with established CVD and had no significant effect on the incidence of cardiovascular events or death. © 2019 The Author

    NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

    No full text
    Xenarthrans—anteaters, sloths, and armadillos—have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, 10 anteaters, and 6 sloths. Our data set includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the southern United States, Mexico, and Caribbean countries at the northern portion of the Neotropics, to the austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n = 5,941), and Cyclopes sp. have the fewest (n = 240). The armadillo species with the most data is Dasypus novemcinctus (n = 11,588), and the fewest data are recorded for Calyptophractus retusus (n = 33). With regard to sloth species, Bradypus variegatus has the most records (n = 962), and Bradypus pygmaeus has the fewest (n = 12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other data sets of Neotropical Series that will become available very soon (i.e., Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans data set. Please cite this data paper when using its data in publications. We also request that researchers and teachers inform us of how they are using these data

    NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics

    No full text
    Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data

    Search for a charged Higgs boson decaying into a heavy neutral Higgs boson and a W boson in proton-proton collisions at s=\sqrt{s} = 13 TeV

    No full text
    A search for a charged Higgs boson H~±{\mathrm{\tilde{H}^{\pm}}} decaying into a heavy neutral Higgs boson H and a W boson is presented. The analysis targets the H decay into a pair of tau leptons with at least one of them decaying hadronically and with an additional electron or muon present in the event. The search is based on proton-proton collision data recorded by the CMS experiment during 2016-2018 at s=\sqrt{s} = 13 TeV, corresponding to an integrated luminosity of 138 fb1^{-1}. The data are consistent with standard model background expectations. Upper limits at 95% confidence level are set on the product of the cross section and branching fraction for an H~±{\mathrm{\tilde{H}^{\pm}}} in the mass range of 300-700 GeV, assuming an H with a mass of 200 GeV. The observed limits range from 0.085 pb for an H~±{\mathrm{\tilde{H}^{\pm}}} mass of 300 GeV to 0.019 pb for a mass of 700 GeV. These are the first limits on H~±{\mathrm{\tilde{H}^{\pm}}} production in the H~±HW±{\mathrm{\tilde{H}^{\pm}}} \to \mathrm{H} \mathrm{W^{\pm}} decay channel at the LHC.A search for a charged Higgs boson H±^{±} decaying into a heavy neutral Higgs boson H and a W boson is presented.

    Measurement of the double-differential inclusive jet cross section in proton-proton collisions at s\sqrt{s} = 5.02 TeV

    No full text
    International audienceThe inclusive jet cross section is measured as a function of jet transverse momentum pTp_\mathrm{T} and rapidity yy. The measurement is performed using proton-proton collision data at s\sqrt{s} = 5.02 TeV, recorded by the CMS experiment at the LHC, corresponding to an integrated luminosity of 27.4 pb1^{-1}. The jets are reconstructed with the anti-kTk_\mathrm{T} algorithm using a distance parameter of RR = 0.4, within the rapidity interval y\lvert y\rvert<\lt 2, and across the kinematic range 0.06 <\ltpTp_\mathrm{T}<\lt 1 TeV. The jet cross section is unfolded from detector to particle level using the determined jet response and resolution. The results are compared to predictions of perturbative quantum chromodynamics, calculated at both next-to-leading order and next-to-next-to-leading order. The predictions are corrected for nonperturbative effects, and presented for a variety of parton distribution functions and choices of the renormalization/factorization scales and the strong coupling αS\alpha_\mathrm{S}
