Abstract The aim is to determine the prevalence of sarcopenia components and associations with socioeconomic variables in older persons living in rural areas in the state of Ceará, Brazil. We conducted a cross-sectional study with 274 older adults. Muscle mass was assessed using muscle mass index (MMI), measured by bioelectrical impedance analysis and calf circumference. Muscle strength (MS) was assessed using the handgrip test. Physical performance was measured using the walk test to calculate gait speed (GS) and the timed up-and-go test. Probable sarcopenia was defined as the presence of low MS, while confirmed sarcopenia was defined as the presence of low MS and low MMI. Severe sarcopenia was defined as the presence of the latter two criteria and slow GS. We tested for associations between sociodemographic characteristics and lifestyle habits and the components of sarcopenia. The logistic regression produced the following results: i) prevalence of low MS was higher among men, individuals aged >69 years, and in those not working at the time of the study; ii) the prevalence of low MMI was higher in individuals aged >69 years, those not living with a spouse, and those with an inadequate level of physical activity; iii) the prevalence of slow GS was higher in individuals aged >69 years, those who had lived in rural areas for less than 30 years, and those not working at the time of the study.

Resumo O objetivo é estimar prevalência de componentes da sarcopenia e associações com variáveis socioeconômicas em idosos de população rural do Ceará. Estudo transversal com 274 idosos. Massa muscular foi determinada por Índice de Massa Muscular (IMM) por bioimpedância elétrica e por circunferência da panturrilha; força muscular (FM) por teste de preensão palmar; e desempenho físico por testes da caminhada (VC) e Timed-up-and-go. Provável sarcopenia foi caracterizada por diminuição da FM, sarcopenia quando associada a diminuição do IMM, e sarcopenia grave quando estes dois foram acompanhados de baixa VC. Foram estimadas associações entre condições sociodemográficas, hábitos de vida e componentes da sarcopenia. Na regressão logística, foi observada frequência mais elevada: i) no sexo masculino, idade>69 anos, e nos que não trabalham, entre os idosos com FM diminuída; ii) com idade>69 anos, nos que não moram com o cônjuge, e nos que não praticam atividade física num nível adequado, entre os idosos com IMM diminuído; iii) com idade>69 anos, nos que residem na zona rural há menos que 30 anos, e nos que não trabalham, entre os idosos com VC diminuída.

Abstract This work describes the circulation over the continental slope and the São Paulo Plateau in the Santos Basin during the SANSED winter 2019 survey. The cruise consisted of four legs in the period between June, 11 and August, 03 2019. The observed circulation is dominated by the Atlantic southwestern boundary current regime and remotely-generated anticyclones and cyclones. The former is composed by the Brazil Current, the Intermediate Western Boundary Current and their mesoscale meanders; the latter are 300km vortical rings with origin in the eastern side of the South Atlantic Basin. A Lagrangian scheme applied over satellite altimeter maps indicate that the origin of these rings is primarily the Cape Basin of South Africa. The interaction between the boundary currents, their cyclonic meanders, and the anticyclonic rings is complex, and varies widely. During the SANSED winter 2019 survey period, three anticyclones interacted with the Brazil Current, instabilizing it, forming dipoles with the current cyclonic meanders, leading to their downstream propagation. Ancienter cyclonic eddies within Santos Basin may interfere with the propagation of the large anticyclones further south. In addition, the continuous arrival of remotely-originated anticyclones, the larger portion over the São Paulo Plateau presented a tendency of counter-clockwise circulation during the whole cruise period.

Abstract This study describes the hydrography and water masses of the Santos Basin Continental Shelf (SBCS) during two hydrographic campaigns (SANAGU, SANSED) in 2019. Coastal Water (CW) is the dominant water mass in the southern portion of the SBCS, with relatively low salinity values (S<35.5 g kg–1), and satellite data show that local precipitation and river discharge could not account for the low salinity observed during the cruises in the southern region of the domain. The low salinity observed is explained by the transport from the south influenced by Subtropical Shelf Water (STSW), which was influenced by the La Plata River discharge. In the northern region of the SBCS, the South Atlantic Central Water (SACW) dominates the bottom layers of the water column, with the wind playing a major role in the uplift of this water mass, as evidenced by a wind impulse analysis. In this part of the shelf, Tropical Water (TW) was the second water mass in volume and occupied the surface layers and offshore the shelf. CW is restricted to a thin surface layer, which reaches distances of a few kilometers from the coast. Our analysis show the differences in the hydrographic structure of the SBCS and suggests that the SBCS can be divided in two regions with distinct characteristics: 1) the area southwest of São Sebastião, where the hydrographic parameters were modulated by the presence of the Subtropical Shelf Water (STSW); 2) the area northeast of São Sebastião, where the uplifting of SACW was the dominant process.

Abstract This study evaluated the bioavailability of polycyclic aromatic hydrocarbons (PAHs) in Santos Bay (SB) and the adjacent Santos Continental Shelf (SCS) in Brazil. Biliary metabolites were measured in several fish species to establish a baseline for future monitoring programs. Bile samples from different species of fish were collected monthly from July to December 2005 in SB, and in August 2005 and February 2006 on SCS. Metabolite concentrations were determined using high-performance liquid chromatography with fluorescence detectors. Naphthalene, phenanthrene, and benzo[a]pyrene metabolite concentrations ranged from 24 to 810 µg g -1 of bile, 1.8 to 68 µg g -1 of bile, and below the limit of quantitation to 1.3 µg g -1 of bile, respectively. Despite its high concentrations, the levels of naphthalene metabolites were in regions of low-contamination, while benzo[a]pyrene metabolite were in the same range as those reported in moderately contaminated areas, which may indicate pyrolytic contamination by PAHs. No significant differences in the metabolite concentrations were found between the SB and the SCS samples or during the periods of collection. Future studies with a single biomonitoring species should be conducted, considering age, sex, and feeding condition of the individuals. The metabolite data presented in this study is an important baseline information for this urbanized region, which hosts several sources of contaminants.

Abstract The Santos Basin (SB) is the main petroliferous basin in the Brazilian continental margin and one of the most studied marine areas in Brazil. However, historical data suggest that new efforts should be carried out to acquire quantitative biological data, especially in the deep sea, to establish the baseline of essential ocean variables in different ecosystems for future monitoring programs. The Brazilian energy company Petrobras planned and executed 24 oceanographic cruises over a period of 2 years to assess the benthic (SANSED cruise) and pelagic (SANAGU cruise) systems of the SB (356 days at sea in 2019 and 2021/2022). These efforts were part of the Santos Project, which comprised a comprehensive environmental study aimed at investigating benthic and pelagic variables to characterize ecology, biogeochemistry, thermohaline properties of water masses, and ocean circulation patterns, geomorphology, and sedimentology, as well as organic and inorganic chemistry. Here we present the detailed sampling designs and the field methods employed on board, during the SB scientific cruises. All sampling protocols were based on standardized approaches. For the benthos analyses, triplicate sediment samples were performed using a GOMEX-type box corer (0.25 m²) or a large modified Van Veen grab (0.75 m²) at 100 stations ranging from 25 to 2400 m depth. At each station, 25 geochemical and physico-chemical parameters were analyzed in addition to micro-, meio-, and macrofauna and living foraminifera samples. For the pelagic system, 60 stations were selected to investigate the plankton community, ranging in size from pico- to macroplankton, through vertical, horizontal, and oblique net hauls (20, 200, and 500 μm mesh size), as well as 25 biogeochemical parameters collected with an aid of a CTD-rosette sampler. Part of this scientific information also serves the Regional Environmental Characterization Project (PCR-BS) in support of Petrobras’ Santos Basin drilling licensing process led by the Brazilian Environmental Agency – IBAMA. This project contributes to the sustainable development of the SB, in line with the guidelines of the United Nations Decade of Ocean Science for Sustainable Development.

The centralization of care for patients with sickle cell diseases through the creation of reference centers through the Ministry of Health Ordinance No. 1,018/2005, enabled better monitoring of these patients. This study characterized the sociodemographic and clinical profile of patients with sickle cell diseases treated at reference centers in the city of Salvador. Women represented the largest portion of patients registered at the centers and were older and more educated than men. More than 90.0% of patients are single, demonstrating the difficulty of people with sickle cell disease to socialize due to the stigma of the disease. The most common clinical manifestations were pain crises and jaundice, and the most common complications were hospitalizations due to pain crises and blood transfusion. Associations were observed between sex and stroke, between genotype and lower limb ulcers and blood transfusion. A low percentage of patients with osteonecrosis (8.8%) was also observed, indicating possible underreporting. The low percentages of patients who use morphine and hydroxyurea point to the need to expand the offer of these drugs to reduce pain crises and improve the quality of life of patients.

La centralización de la atención a los pacientes con anemia falciforme mediante la creación de centros de referencia a través de la Ordenanza del Ministerio de Salud Nº 1.018 / 2005, permitió un mejor seguimiento de estos pacientes. Este estudio caracterizó el perfil sociodemográfico y clínico de los pacientes con drepanocitosis atendidos en centros de referencia de la ciudad de Salvador. Las mujeres representaban la mayor parte de los pacientes registrados en los centros y eran mayores y tenían más educación que los hombres. Más del 90,0% de los pacientes son solteros, lo que demuestra la dificultad de las personas con anemia falciforme para socializar debido al estigma de la enfermedad. Las manifestaciones clínicas más frecuentes fueron crisis de dolor e ictericia, y las complicaciones más frecuentes fueron hospitalizaciones por crisis de dolor y transfusión de sangre. Se observaron asociaciones entre sexo y accidente cerebrovascular, entre genotipo y úlceras de miembros inferiores y transfusión de sangre. También se observó un bajo porcentaje de pacientes con osteonecrosis (8,8%), lo que indica un posible subregistro. Los bajos porcentajes de pacientes que utilizan morfina e hidroxiurea apuntan a la necesidad de ampliar la oferta de estos fármacos para reducir las crisis de dolor y mejorar la calidad de vida de los pacientes.

A centralização do atendimento dos pacientes com doenças falciformes através da criação de centros de referência possibilitou um melhor acompanhamento desses pacientes. Este estudo caracterizou o perfil sociodemográfico e clínico dos pacientes com doenças falciformes atendidos nos centros de referência no município de Salvador. Os resultados deste estudo corroboram com a literatura e podem ajudar a melhorar os serviços oferecidos nos centros de referência pesquisados. As mulheres representaram a maior parcela dos pacientes registrados nos centros e com maior faixa etária e escolaridade do que os homens. Mais de 90,0% dos pacientes são solteiros, demonstrando a dificuldade das pessoas com doenças falciformes se socializarem devido ao estigma da doença. As manifestações clínicas mais comuns foram as crises álgicas e a icterícia e as intercorrências mais comuns foram internações devido as crises álgicas e hemotransfusão. Foram observadas associações entre sexo e acidente vascular cerebral, entre o genótipo e úlceras de membros inferiores e hemotransfusão. Também foi observado um percentual baixo de pacientes com osteonecrose indicando possível subnotificação. Os percentuais baixos de pacientes que fazem uso da morfina e hidroxiureia apontam para a necessidade de ampliar a oferta desses medicamentos para diminuir as crises álgicas e melhorar a qualidade de vida dos pacientes.

RESUMO: Esta pesquisa avaliou os efeitos da irrigação no crescimento e na produtividade da mandioca irrigada nos Tabuleiros Costeiros alagoanos. O plantio foi feito em blocos casualizados, com seis tratamentos e quatro repetições. Os tratamentos foram níveis de irrigação em função da evapotranspiração da cultura - ETC (L0 = 0% (sequeiro), L1 = 40%, L2 = 80%, L3 = 120%, L4 = 160% e L5 = 200% da ETC). A lâmina total foi definida como o total da irrigação mais a chuva efetiva. A evapotranspiração anual da cultura da mandioca nos Tabuleiros Costeiros de Alagoas é 1.030 mm. O crescimento das plantas aumentou significativamente com a irrigação e os valores máximos das seguintes variáveis são: índice de área foliar = 7,6; comprimento de raízes comerciais = 49 cm; produtividades (física e econômica) máximas de raízes comerciais = 94 t ha-1 e biomassa total = 149 t ha-1 e o índice de colheita = 0,66, todos obtidos com lâminas de irrigação totais (chuva efetiva mais irrigação) entre 817 e 963 mm. Por fim, ratifica-se que entender o crescimento, as produtividades agrícola e economicamente viáveis da mandioca irrigada, é fator indispensável para se fazer um bom manejo da cultura, principalmente, em regiões com irregularidade de chuvas como o nordeste brasileiro.

ABSTRACT: This research evaluated the effects of the irrigation on growth and productivity of irrigated cassava in the Coastal Plateaus of Alagoas. The planting was done in randomized blocks, with six treatments and four replications. The treatments were irrigation levels in function of crop evapotranspiration - ETC (L0 = 0% (rainfed), L1 = 40%, L2 = 80%, L3 = 120%, L4 = 160% and L5 = 200% of ETC). The total water applied was defined as the total irrigation plus the effective rain. The annual evapotranspiration of the cassava plantations in the Costal Plateaus of Alagoas, was 1,030 mm. Plant growth increased significantly with irrigation and the maximum values of the following variables are: leaf area index = 7.6, length of commercial roots = 49 cm, maximum productivity (physical and economic) of commercial roots = 94 Mg ha-1 and total biomass = 149 Mg ha-1 and the harvest index = 0.66, all obtained with total irrigation depths (effective rain plus irrigation) between 817 and 963 mm. Finally, it is ratified that understanding the growth, the agricultural and economically viable productivity of irrigated cassava, is an indispensable factor for good management of the crop, especially in regions with irregular rainfall such as the Northeast of Brazil.

Abstract The banana is one of the most consumed fruits in the world, but it has little shelf life due to its high water activity. Drying is able to increase shelf life and pre-treatments can optimize the process. The objective was to study the solar drying kinetics and evaluate the effect of pre-treatments on the drying kinetics and physico-chemical quality of 'Prata' bananas. The drying was carried out in a solar dryer and the pre-treatments consisted of immersing the samples in solutions of water, citric acid (1%) and lemon juice (10%). Water loss, drying kinetics, mathematical models and physical-chemical and colorimetric characteristics of fresh and dried bananas were evaluated. The drying rate was higher at the beginning and stabilized after 20 hours. The mathematical model of Midilli and Kucuk was the one that best fit the experimental data. The water content, ascorbic acid and the parameters L *, b *, C * and h ° reduced after drying. Reducing sugars and a * coordinate increased and the acidity was not changed with drying. The solar drying of 'Prata' bananas is a sustainable and economical way to make a product available with a longer shelf life.

Abstract Microalgae are considered a rich source of biostimulants for plants, as an excellent business opportunity for the agricultural sector, as they can activate plant metabolism, contributing to the improvement in physiological performance, phytomass and, subsequently, vigor and quality of seedlings. The objective of this work was to evaluate the potential of Spirulina platensis biomass, in enabling improvements in physiological performance, phytomass and, subsequently, vigor and quality of cashew rootstock seedlings. The experiment was carried out in a greenhouse in a completely randomized design, in a 4 x 2 factorial scheme (concentrations x rootstock), with three replications. The concentrations used were 0%, 0.04%, 0.08%, and 0.12% and the FAGA and CCP 76 genotypes. The seeds were immersed in the solutions for 12 hours. Applications were made via the leaves at 30 days after sowing (DAS), with an interval of seven days between each application and at 90 DAS evaluations were made. The FAGA and CCP 76 genotypes showed a positive response to the supply of S. platensis, with concentrations 0.04% and 0.08% which provided greater root length, aerial part length, number of leaves, diameter and leaf area. Concentrations 0.04% and 0.08% also promoted better percentages in the physiology of the CCP 76 genotype, while the FAGA genotype showed opposite action, which may be related to the mode of action of the microalgae on the different genetic and phenotypic characteristics of each genotype. The 0.12% concentration provided greater accumulations of aerial part and total dry mass to the genotypes.

Resumo Esse estudo tem como objetivo refletir sobre os Determinantes Sociais da Saúde na cidade de Belém (PA) e a atuação da Atenção Primária à Saúde no enfrentamento à pandemia de COVID-19. A partir da utilização de dados secundários e da caracterização do município, foi possível refletir sobre os aspectos de habitação, saneamento básico e renda da população na distribuição dos casos de COVID-19 na cidade. Evidenciou-se que as desigualdades sociais entre os Distritos Administrativos são preponderantes, todavia não houve a elaboração de um plano de ação que considerasse os impactos de COVID-19 nas populações em vulnerabilidade social. Ao investigar o papel da Atenção Primária à Saúde no controle da pandemia, percebe-se que a baixa cobertura da Estratégia Saúde da Família aliada às ações desarticuladas entre município e estado podem ter contribuído para o agravamento epidemiológico da COVID-19 em Belém. O plano de contingência não conseguiu implementar políticas contundentes para o controle da doença, focando na medicalização e nas ações hospitalocêntricas para os casos graves, enquanto as unidades de saúde foram subutilizadas, faltando estabelecer um fluxo coordenado de cuidados para os pacientes com a COVID-19, uma doença fortemente atrelada às iniquidades sociais.

Abstract This study aims to reflect on the Social Determinants of Health in the city of Belém (PA) and the performance of Primary Health Care in coping with the COVID-19 pandemic. From the use of secondary data and the characterization of the municipality, it was possible to reflect on the aspects of housing, basic sanitation and income of the population in the distribution of COVID-19 cases in the city. It was evidenced that social inequalities between Administrative Districts are predominant, however there was no elaboration of an action plan that considered the impacts of COVID-19 on populations in social vulnerability. When investigating the role of Primary Health Care in pandemic control, it is perceived that the low coverage of the Family Health Strategy combined with the disjointed actions between municipality and state may have contributed to the epidemiological worsening of COVID-19 in Belém. The contingency plan failed to implement forceful policies for the control of the disease, focusing on medicalization and hospital-centered actions for severe cases, while health units were underutilized, lacking to establish a coordinated flow of care for patients with COVID-19, a disease strongly linked to social inequities.

SUMMARY The search describes the spectrophotometric reaction of the Cu (II)-PAN (1-(2-pyridilazo) -2-naphthol) complex and determines the concentration of copper (II) in manioc spirit (Tiquira). For this, we dimensioned the reaction for the studies of complex absorption, pH, stability, stoichiometric ratio, interferences, correlation, and recovery. After this step, we determined the concentration of copper (II) in five samples of beverages distilled artisanal from five municipalities of the State of Maranhão. The results show that the complex absorbs at 548 nm at pH 6, is stable at a time of 7 hours in minimum 1:1 stoichiometric proportions of the binder and metal, has a detection limit in 3.3 X 10-2 mg L-1, range (R2= 0.9990), standard deviation= 0.0035 and recovery at 104.54 ± 7.0, and the main interfering ions are iron (III) and cobalt (II). In the brandy, we find that the copper content is above that allowed by Brazilian legislation.

RESUMO A pesquisa descreve a reação espectrofotométrica do complexo Cu(II)-PAN (1-(2-piridilazo)-2-naftol) e determina a concentração de cobre (II) em aguardente de mandioca (Tiquira). Para isso, dimensionamos a reação para os estudos de absorção do complexo, pH, estabilidade, proporção estequiométrica, interferentes, correlação e recuperação. Após essa etapa, determinamos a concentração de cobre(II) em cinco amostras de bebidas destiladas artesanalmente de cinco municípios do Estado do Maranhão. O resultados mostram que o complexo absorve em 548 nm em pH 6, é estável em um tempo de 7 horas em proporções estequiométrica mínima de 1:1 do ligante e metal, possui limite de detecção em 3,3 X 10-2 mg L-1, faixa de linearidade de 1 X 10-6 a 1 X 10-5 mol L-1, correlação (R2= 0,9990), desvio padrão=0,0035 e recuperação em 104,54 ± 7,01 e os principais íons interferentes são o ferro (III) e o cobalto (II). Na aguardente, constatamos que o teor de cobre está acima do permitido pela legislação brasileira.

SUMMARY: Few studies have focused on the in vitro multiplication methods for Eucalyptus cloeziana. In this work we developed an indirect organogenesis protocol to obtain micropropagated plants. The interactions of plant growth regulators in juvenile tissues were evaluated. Hypocotyl, cotyledon and root tissues obtained from in vitro germinated seedlings were subjected to combinations of α-naphthaleneacetic acid (NAA), thidiazuron (TDZ) and 2,4-dichlorophenoxyacetic acid (2,4-D). In vitro callogenesis, adventitious bud induction, shoot elongation, and ex vitro survival and rooting were evaluated. Callogenic structures were observed in all evaluated tissues. Morphogenic characteristics related to the meristematic center was observed. The tissues that presented the callus mass were subcultured in a regeneration culture medium supplemented with 1.0 mg L-1 of 6-benzylaminopurine (BAP). Only hypocotyl and cotyledon induced adventitious bud and shoot elongation. Hypocotyl subjected to 2.0 mg L-1 TDZ had the highest number of elongated shoots. The two tissues (i.e., hypocotyl and cotyledon) combined with thidiazuron were characterized by the ex vitro survival of microcuttings and by adventitious rooting. Results confirmed tissue culture efficiency for microplants production by indirect organogenesis from hypocotyl and cotyledon cultivated with TDZ, and its implementation can be an alternative for forest tree breeding programs of E. cloeziana.

RESUMEN: Pocos estudios se han centrado en los métodos de multiplicación in vitro para Eucalyptus cloeziana. En este trabajo se desarrolló un protocolo de organogénesis indirecta para obtener plantas micropropagadas. Se evaluaron las interacciones de los reguladores del crecimiento en tejidos juveniles. Los tejidos del hipocótilo, cotiledón y raíces obtenidos de plántulas germinadas in vitro se sometieron a combinaciones de ácido α-naftaleneacético (ANA), tidiazurón (TDZ) y ácido 2,4-diclorofenoxiacético (2,4-D). Se evaluaron la callogénesis in vitro, la inducción adventicia de yemas, el alargamiento de brotes, y la sobrevivencia y enraizamiento ex vitro. Se observaron estructuras calogénicas en todos los tejidos evaluados. Se observaron características morfogénicas relacionadas con la formación de centros meristemáticos. Los tejidos que presentaron la masa del callo fueron subcultivados en medio de cultivo de regeneración suplementado con 1,0 mg L-1 de 6-bencilaminopurina (BAP), y solo los tejidos del hipocótilo y cotiledón formaron yemas adventicias y brotes alargados. Los tejidos del hipocótilo sometidos a 2,0 mg L-1 de tidiazuron obtuvieron mayor número de brotes alargados. Los dos tejidos (hipocótilo y cotiledón) combinados con TDZ se caracterizaron por sobrevivencia y el enraizamiento adventicio ex vitro de las microestacas. Los resultados confirmaron la eficiencia del cultivo de tejidos para la producción de microplantas por organogénesis indirecta a partir de tejidos del hipocótilo y cotiledón cultivados con TDZ y su implementación puede ser una alternativa para los programas de mejoramiento forestal de E. cloeziana.

RESUMO O objetivo deste estudo foi descrever comportamentos de riscos para a saúde em adolescentes e verificar as possíveis associações entre estes. Tratou-se de um estudo transversal, realizado na cidade de Teresina/PI, com 540 adolescentes de 14 a 19 anos. O instrumento utilizado para o levantamento de dados foi uma adaptação do questionário do projeto “COMPAC”. Cerca de 35% dos adolescentes relataram assistir televisão por quatro horas, apenas 22% relataram o uso do computador de uma a duas horas, enquanto 60% afirmaram usar o celular por mais de quatro horas durante a semana. O percentual de adolescentes considerados fisicamente inativos foi superior a 35%. Mais de 15% dos adolescentes consumia bebida alcóolica uma a duas vezes e 11% consumia até duas doses por semana. A quantidade de doses diárias de bebidas alcóolicas foi significativamente associada ao tempo assistindo televisão por semana (OR = 2,45; p = 0,040) e no fim de semana (OR = 2,05; p = 0,032). Foi encontrada alta prevalência de adolescentes fisicamente inativos e de tempo despendido em comportamentos sedentários. Além disso, o comportamento sedentário esteve associado ao consumo de bebidas alcoólicas, Assim, é importante repensar o uso da televisão e do uso álcool no cotidiano dos adolescentes.

Abstract The objective of this study was to describe health risk behaviors in adolescents and to verify the possible associations between them. It was a cross-sectional study conducted in Teresina / PI, with 540 adolescents aged 14 to 19 years. The instrument used for data collection was an adaptation of the “COMPAC” project questionnaire. About 35% of teens reported watching television for four hours, only 22% reported using their computer for one to two hours, while 60% reported using their cell phone for more than four hours during the week. The percentage of adolescents considered physically inactive was greater than 35%. More than 15% of adolescents consumed alcoholic beverages one to two times, and 11% consumed up to two doses per week. The amount of daily doses of alcoholic beverages was significantly associated with TV watching time per week (OR = 2.45, p = 0.040) and at the weekend (OR = 2.05, p = 0.032). It was found a high prevalence of physically inactive adolescents and time spent in sedentary behaviors. In addition, sedentary behavior was associated with alcohol consumption. Thus, it is important to rethink television and alcohol use in adolescents’ daily lives.
