RESUMO Os resíduos orgânicos disponíveis na região Oeste do Maranhão, Brasil, são abundantes, devido à atividade agropecuária. Estes podem ser utilizados na composição de substratos para produção de mudas de mogno africano, porém há necessidade de demonstrar a eficiência técnica de resíduos orgânicos com solos da região. O objetivo foi avaliar substratos compostos de proporções varáveis de terra de diferente textura e resíduos orgânicos, para a obtenção de mudas de mogno africano de boa qualidade. O experimento foi conduzido em duas etapas, uma em viveiro florestal e outra no campo, ambos localizados no bioma Cerrado, Oeste do Maranhão, região Nordeste do Brasil. O delineamento foi em blocos casualizados, com onze tratamentos e sete repetições. As variáveis morfológicas de crescimento e qualidade foram avaliadas por 105 dias no viveiro e 270 dias no campo. Os resultados demonstraram que todos os substratos produziram mudas com índice de robustez e índice de qualidade de Dickson adequados, e as mudas de mogno africano produzidas nos substratos com proporção que vária entre 70 a 30% de solo, 15 a 30% de esterco bovino curtido e 15 a 20% de casca de arroz carbonizada apresentaram melhor padrão de qualidade considerando-se os maiores valores de teor de nutrientes, características morfológicas e índice de qualidade de Dickson. No entanto, ao serem plantadas no campo, apenas as mudas que foram produzidas nos substratos com terra de subsolo de textura argilosa, com até 20% de casca de arroz carbonizada, apresentaram maior crescimento em altura, pois o substrato permaneceu aderido à raiz ao serem retirados do recipiente. Portanto, a aderência do substrato ao sistema radicular das mudas foi o fator preponderante para o maior crescimento das mudas em condições de campo.

ABSTRACT The organic residues can be used in the composition of substrates, but there is a need to demonstrate the technical efficiency of organic residues. The objective was to evaluate substrates composed of varying proportions of soil of different texture and organic residues, in order to obtain good quality African mahogany seedlings. The experiment was carried out in two stages, one in a forest nursery and the other in the field, both located in the Cerrado biome, Western Maranhão, Northeast region of Brazil. The design was in randomized blocks, with eleven treatments and seven replications. The morphological variables of growth and quality were evaluated for 105 days in the nursery and 270 days in the field. The results showed that all substrates produced seedlings with adequate robustness and Dickson quality index. The seedlings produced in substrates with proportions ranging from 70 to 30% of soil, 15 to 30% of tanned cattle manure and 15 to 20% of carbonized rice husks presented a better quality standard, considering the higher values of nutrient content, morphological characteristics and Dickson quality index. However, when planted in the field, only seedlings that were produced in substrates with clayey textured soil, with up to 20% of carbonized rice husk, showed greater growth in height, as the substrate remained adhered to the root when removed from the container. Therefore, the adherence of the substrate to the root system of the seedlings was the main factor for the greater growth of the seedlings under field conditions.

ABSTRACT BACKGROUND: High prevalence of human immunodeficiency virus (HIV) infection and occurrence of drug-resistant strains have been recorded in northern Brazil. Abandonment of treatment and insufficient and inadequate adherence to antiretroviral therapy (ART) among people living with HIV/AIDS (PLWHA) have been recorded in the metropolitan area of Belém, the capital of the state of Pará. OBJECTIVES: To identify the sociodemographic profile and level of adherence to ART among women seen at a referral unit in the interior of Pará, northern Brazil. DESIGN AND SETTING: Cross-sectional study at a referral unit for care for PLWHA. METHODS: We included 86 women living with HIV/AIDS (WLWHA) in the Rio Caeté integrated region, northeastern Pará. Social, demographic and behavioral information, as well as the ART level, were obtained using forms that have been described in the scientific literature. Logistic regression models were used to assess associations of variables with ART. RESULTS: Most WLWHA were single (52.4%), young (47.7%) and heterosexual (97.7%), had low levels of education (63.0%), were unemployed (69.8%), had one sexual partner (75.7%), used condoms (46.7%) and were not using either licit drugs (68.7%) or illicit drugs (89.6%). Their adherence level was classified as insufficient , and only their viral load showed an association with ART. CONCLUSIONS: The participants’ low level of education and poor socioeconomic conditions may have been interfering with their adherence to ART. Such influences can be minimized through multiprofessional interventions that take the individuality of women served by the healthcare service into consideration.

ABSTRACT Chemical engineering optimization represents a significant challenge due to the complexity of the mathematical models that are frequently required in this area. These models are normally associated with nonlinear equations that represent mass, energy, and momentum balances, which are submitted to physical, constitutive, environmental, and design limitations. The design of chemical systems is generally carried out by considering the model, the vector of design variables, and system parameters as deterministic values, i.e., small variations in these quantities do not affect the objective function. In this contribution, a new methodology based on a double loop iteration process to evaluate the influence of uncertainties on chemical engineering design is proposed. The inner optimization loop is used to find the solution associated with the highest probability value by using the so-called Inverse Reliability Analysis and the outer loop is the regular optimization loop used to determine the vector of design variables. For this aim, the Multi-Objective Optimization Water Cycle Algorithm is improved, adopting a mechanism of neighborhood exploration. For illustration purposes, the proposed methodology is applied to mathematical functions and to chemical engineering design. The obtained results demonstrate that the proposed strategy represents an interesting alternative to reliability design in chemical engineering.

Abstract Aim: To verify the association between insufficient level of physical activity and multiple health risk behaviors (HRB) in adolescents. Methods: This is an epidemiological study with cross-sectional design carried out in 2016 with 3,617 adolescents aged 14-19 years and enrolled in the public-school system of Sergipe, northeast Brazil. Data were collected using the Global School-based Student Health Survey (GSHS/WHO). The insufficient level of physical activity was defined as not achieving at least 60 minutes of moderate to vigorous physical activity for 5 days a week. The HRB analyzed were smoking, alcohol consumption, low fruit consumption and exposure to sedentary behavior. The analysis of prevalence odds ratio was used to identify the association between insufficient level of physical activity and HRB, as well as unadjusted and adjusted binary logistic regression for the association between socioeconomic and demographic variables. Results: The prevalence of insufficient level of physical activity was 83.3%. There was association between physical inactivity and low fruit consumption and alcohol consumption (p<0.001). Insufficient level of physical activity was also associated with female sex (OR=1.90, 95% CI, 1.56-2.32), family income of up to 2 minimum wages (OR=1.57, 95% CI, 1.17-2.11), maternal schooling less than 8 years (OR=1.55, 95% CI, 1.28-1.86) and exposure to two different HRB at the same time (OR=1.76, 95% CI, 1.27-2.45). Conclusion: The prevalence of insufficient level of physical activity is high and was associated with multiple HRBs in this understudied population. These findings may support interventions focusing on the cluster of risk behaviors in youth.

Abstract INTRODUCTION: Female sex workers (FSWs) are considered a bridge for transmission of pathogens from high-risk to general populations. We assessed the epidemiological status of syphilis in FSWs along the Pará highway system. METHODS: Two hundred and twenty-two FSWs were interviewed and samples were analyzed using rapid qualitative tests and real-time polymerase chain reaction. RESULTS: The prevalence of syphilis was high (36.94%). The high rate of prostitution, use of illicit drugs, and search for financial resources increased Treponema pallidum transmission through unprotected sex. CONCLUSIONS: Several characteristics of FSWs were identified, which reinforce the need for measures guaranteeing their health and protection.

RESUMO Objetivo: Avaliar o desempenho do Pediatric Index of Mortality (PIM) 2 e do Escore de Risco Ajustado para Cirurgia Cardíaca Congênita (RACHS) no pós-operatório de cardiopatas congênitos. Métodos: Estudo transversal retrospectivo. Foram coletados dados de prontuário para gerar os escores e predições com as técnicas preconizadas, os dados demográficos e os desfechos. Para estatística, utilizaram-se o teste de Mann-Whitney, o teste de Hosmer-Lemeshow, a taxa de mortalidade padronizada, a área sobre a curva COR, qui quadrado, regressão de Poisson com variância robusta e teste de Spearman. Resultados: Foram avaliados 263 pacientes, e 72 foram a óbito (27,4%). Estes apresentaram valores de PIM-2 significativamente maiores que os sobreviventes (p < 0,001). Na classificação RACHS-1, a mortalidade foi progressivamente maior, de acordo com a complexidade do procedimento, com aumento de 3,24 vezes na comparação entre os grupos 6 e 2. A área abaixo da curva COR para o PIM-2 foi 0,81 (IC95% 0,75 - 0,87) e, para RACHS-1, de 0,70 (IC95% 0,63 - 0,77). A RACHS apresentou melhor poder de calibração na amostra analisada. Foi encontrada correlação significativamente positiva entre os resultados de ambos os escores (rs = 0,532; p < 0,001). Conclusão: A RACHS apresentou bom poder de calibração, e RACHS-1 e PIM-2 demonstraram bom desempenho quanto à capacidade de discriminação entre sobreviventes e não sobreviventes. Ainda, foi encontrada correlação positiva entre os resultados dos dois escores de risco.

ABSTRACT Objective: To assess the performance of the Pediatric Index of Mortality (PIM) 2 and the Risk Adjustment for Congenital Heart Surgery (RACHS) in the postoperative period of congenital heart disease patients. Methods: Retrospective cross-sectional study. Data were collected from patient records to generate the scores and predictions using recommended techniques, demographic data and outcomes. The Mann-Whitney test, Hosmer-Lemeshow test, standardized mortality rate, area under the receiver operating characteristic (ROC) curve, chi square test, Poisson regression with robust variance and Spearman's test were used for statistical analysis. Results: A total of 263 patients were evaluated, and 72 died (27.4%). These patients presented significantly higher PIM-2 values than survivors (p < 0.001). In the RACHS-1 classification, mortality was progressively higher according to the complexity of the procedure, with a 3.24-fold increase in the comparison between groups 6 and 2. The area under the ROC curve for PIM-2 was 0.81 (95%CI 0.75 - 0.87), while for RACHS-1, it was 0.70 (95%CI 0.63 - 0.77). The RACHS presented better calibration power in the sample analyzed. A significantly positive correlation was found between the results of both scores (rs = 0.532; p < 0.001). Conclusion: RACHS presented good calibration power, and RACHS-1 and PIM-2 demonstrated good performance with regard to their discriminating capacities between survivors and non-survivors. Moreover, a positive correlation was found between the results of the two risk scores.

RESUMO O artigo apresenta práticas que conformam a formação e a atuação de coordenadoras pedagógicas de cinco escolas da periferia do município de Belém, estado do Pará, tendo por base as novas diretrizes curriculares nacionais para a formação inicial e continuada dos profissionais do magistério da Educação Básica, de 1 de julho de 2015. Nossa intenção é analisar como o percurso formativo desses profissionais (des)favorece práticas pedagógicas atentas aos “sentidos de diversidade e desigualdade”. Analisaremos os processos formativos e as práticas pedagógicas das coordenadoras atuantes em escolas públicas de Ensino Fundamental e Médio, tendo a compreensão de que a interferência de técnicos pedagógicos sobre os procedimentos teóricos e metodológicos é decisiva para a condução do trabalho pedagógico de uma instituição escolar, uma vez que estes profissionais figuram entre os que atuam na definição de políticas educacionais internas. Entre as conclusões realizadas, constatamos, por meio de documentos escritos e orais, o descompasso entre a formação para uma escola ideal e o parco conhecimento das relações contextuais de desigualdades, afetando estruturalmente as práticas pedagógicas.

ABSTRACT This article presents practices that form the base of pedagogical coordinators’ formation and activities. The subjects work in five schools in the outskirts of Belém (Pará, Brazil), and try to imbed their methods on the new national curriculum guidelines for elementary teachers’ initial and ongoing formation, of July 1st, 2015. We intend to analyze how these professionals’ formation favors (or does not) teaching practices attentive to “the meanings of diversity and inequality”. We will analyze educational processes and teaching praxes of pedagogical coordinators who work at public primary and secondary schools, because we understand that pedagogical technicians grounded in theoretical and methodological procedures are crucial to the conduction of educational labor at school, since those professionals are among the ones who deal with the definition of internal educational policies. Through written and oral documents, conclusions suggest that the mismatch between formation for an ideal school and the meager knowledge of contextual relations of inequality structurally affects pedagogical practices.

Abstract In the present paper, a simplified homogenized beam theory is used in the context of a numerical investigation regarding the dynamic behavior of a rotating composite hollow shaft. For this aim, a horizontal flexible composite shaft and a rigid disc form the considered simple supported rotating system. The mathematical model of the rotor is derived from the Lagrange’s equation and the Rayleigh-Ritz method, which is obtained from the strain and kinetic energies of the disc and shaft, and the mass unbalance. In this case, a convergence procedure is carried out in terms of the vibration modes to obtain a representative model for the rotor system. Therefore, the proposed analysis is performed in both frequency and time domains, in which the frequency response functions, the unbalance responses, the Campbell diagram, and the orbits are numerically determined. Additionally, the instability threshold of the rotor system is obtained. This study illustrates the convenience of the composite hollow shafts for rotor dynamics applications.

Resumo O feijão-caupi tem grande importância econômica, alimentar e social. No Nordeste brasileiro, notadamente nas regiões semiáridas, sua produção é limitada pelo déficit hídrico, sendo necessário identificar genótipos tolerantes atrelados ao uso de tecnologias em seu cultivo. Com isto, objetivou-se avaliar o rendimento de fitomassa e as trocas gasosas de genótipos de feijão-caupi cultivados em diferentes técnicas de conservação de água. O experimento foi realizado em campo, no município de Pombal, na Paraíba, estudando-se quatro técnicas de retenção de água in situ (camalhão, sulco, bacia e sistema convencional) e seis genótipos de feijão-caupi (1. Costela de Vaca, 2. BRS Itaim, 3. BRS Guariba, 4. BR-17 Gurguéia, 5. BRS Potengi e 6. BRS Aracé) semeados no espaçamento de 0,5 m x 0,5 m, usando o delineamento experimental de blocos ao acaso, com quatro repetições. Os dados das estimativas do rendimento de fitomassa seca e das trocas gasosas das plantas foram submetidos à análise de variância, ao teste F, seguido de testes de comparação de médias, teste de Tukey. O cultivo em sulcos e em camalhão deram melhor resultados do que o sistema convencional de plantio e em bacia. As variedades BRS - Potengi, BRS - Aracé e BRS - Guariba tiveram melhor crescimento e trocas gasosas das plantas.

Abstract The cowpea bean has great economic, nutritive and social importance. In the Northeast, especially in semi-arid regions, cowpea production is limited due to a lack of water, making it necessary to identify tolerant genotypes and cultivation technologies. This study therefore aimed to analyze the dry matter yield and the gas exchange between cowpea genotypes cultivated using different water conservation techniques. The experiment was conducted in the field in the city of Pombal, Paraíba, in order to study four treatments that use different water retention techniques (ridge, groove, basin and conventional system) applying six genotypes of cowpea bean (1. Costela de Vaca, 2. BRS Itaim, 3. BRS Guariba, 4. BR-17 Gurgueia, 5. BRS Potengi e 6. BRS Arace) sowing with 0.5 m x 0.5 m spacing between plants, using the randomized blocks design with four replications. Dry matter yield and gas exchange data were subjected to ANOVA, F test, followed by mean comparison tests, Tukey test. The groove and ridge cultivation techniques had better results than the basin and conventional techniques. The BRS- Potengi, BRS - Aracé e BRS - Guariba genotypes had better growth and gas exchange potential.

Resumo Objetivo: Determinar a prevalência do consumo de frutas e vegetais e identificar a associação com o baixo nível de atividade física, exposição a comportamentos sedentários, consumo de refrigerantes e sobrepeso/obesidade em adolescentes. Métodos: Estudo transversal de base escolar com uma amostra representativa de 3.992 alunos entre 14 e 19 anos do Estado de Sergipe, Brasil. O desfecho foi o baixo consumo de frutas e vegetais (<5 porções/dia). As variáveis independentes foram: nível de atividade física, comportamento sedentário, consumo de refrigerantes e sobrepeso/obesidade. Foram usados o questionário Global Student Health Survey e o peso corporal e altura, bem como o teste do qui-quadrado e regressão logística binária (análise ajustada e bruta). O nível de significância adotado foi de 5%. Resultados: A prevalência de consumo inadequado de frutas e hortaliças foi alta - 88,6% (IC95%=87,6-89,5). Verificou-se maior probabilidade de baixo consumo de frutas e legumes em meninos que estavam expostos a comportamento sedentário (OR=1,63; IC95%=1,18-2,24), que consumiam refrigerantes (OR=3,04; IC95%=2,10-4,40) e com atividade física insuficiente (OR=1,98; IC95%=1,43-2,73) e meninas que consumiam refrigerantes (OR=1,88, IC95%=1,43-2,47) e aquelas com sobrepeso/obesidade (OR=1,63, IC95%=1,19-2,23). Conclusões: Há a necessidade de políticas públicas destinadas a incentivar o consumo de alimentos saudáveis entre os adolescentes.

Abstract Objective: To determine the prevalence of consumption of fruits and vegetables and identify the association with low level of physical activity, exposure to sedentary behavior, consumption of soft drinks and overweight/obesity in adolescents. Methods: This is a cross-sectional school-based study with a representative sample of 3992 students aged 14–19 years from the state of Sergipe, Brazil. The outcome was low consumption of fruits and vegetables (<5servings/day). Independent variables were: level of physical activity, sedentary behavior, consumption of soft drinks, and overweight/obesity. Global Student Health Survey questionnaire and body mass and height measurements were used, as well as chi-square test and crude and adjusted binary logistic regression. The significance level adopted was 5%. Results: The prevalence of inadequate consumption of fruits and vegetables was high – 88.6% (95%CI=87.6–89.5). Higher likelihood of low consumption of fruits and vegetables was verified among boys who were exposed to sedentary behavior (OR=1.63; 95%CI=1.18–2.24), who consumed soft drinks (OR=3.04; 95%CI=2.10–4.40), with insufficiently physical activity (OR=1.98; 95%CI=1.43–2.73) and girls who consumed soft drinks (OR=1.88; 95%CI=1.43–2.47) and those with overweight/obesity (OR=1.63; 95%CI=1.19–2.23). Conclusions: There is a need of public policies aimed at encouraging the consumption of healthy foods among adolescents.

RESUMO Introdução: Poucas evidências destacam aspectos das condições de vida em adolescentes residentes nas áreas urbana e rural. Objetivo: Verificar indicadores das condições de vida associados às prevalências do nível de atividade física abaixo das recomendações (NAFAR) e da exposição ao comportamento sedentário (ECS) em escolares de áreas urbanas e rurais de Sergipe, Brasil. Métodos: Realizou-se um estudo transversal de base escolar. Compuseram a amostra 3.992 escolares, com idade variando de 14 a 19 anos. Resultados: A prevalência de adolescentes com NAFAR foi de 77,5% (urbana 76%; rural 80%) e ECS de 46,7 % (urbana 50,2%; rural 41,2%). Em áreas urbanas, verificou-se a associação da ECS com o território, período de estudo, escolaridade materna, situação ocupacional do adolescente e renda familiar. O NAFAR associou-se com o fato de residir com o pai e com o trabalho do pai. Em áreas rurais, a ECS associou-se ao período de estudo, situação ocupacional do adolescente e a renda familiar. O NAFAR associou-se à situação ocupacional do adolescente. Conclusão: Os resultados mostraram que o NAFAR e a ECS estiveram relacionados a diferentes indicadores de condições de vida, sugerindo intervenções variadas considerando o local de residência.

ABSTRACT Introduction: Little evidence highlights aspects of living conditions in adolescents living in urban and rural areas. Objective: To valuate indicators of living conditions associated to prevalence of physical activity level below the re-commendations (NAFAR) and exposure to sedentary behavior (ECS) in students in urban and rural areas of Sergipe, Brazil. Methods: We conducted a cross-sectional school-based study. The sample was composed of 3,992 students, aged 14-19 years. Results: The prevalence of adolescents with NAFAR was 77.5% (urban, 76%; rural, 80.0%) and ECS 46.7% (urban, 50.2%; rural, 41.2%). In urban areas, there was an association of ECS with the territory, period of study, maternal level of education, the adolescent's occupation and family income. The NAFAR was associated with residing with father and the father's work. In rural areas, ECS was associated to the period of study, the adolescent's occupation and family income. The NAFAR was associated with the adolescent's occupation. Conclusion: The results showed that the NAFAR and ECS were related to different indicators of living conditions, suggesting several interventions considering the place of residence.

Introduction: Illicit drug users (DUs) are vulnerable to hepatitis C virus (HCV) infection. The shared use of illicit drugs is the main method of HCV transmission. Methods: A cross-sectional study was conducted in Breves, in northern Brazil. We surveyed 187 DUs to determine the prevalence of and factors associated with HCV infection. Results: The prevalence of anti-HCV antibodies was 36.9%, and the prevalence of hepatitis C virus-ribonucleic acid (HCV-RNA) was 31%. Hepatitis C virus infection was associated with tattoos, intravenous drug use, shared use of equipment for drug use, drug use for longer than 3 years, and daily drug use. Conclusions: Strategies for preventing and controlling HCV transmission should be implemented among DUs.

INTRODUÇÃO: A autoavaliação negativa da saúde parece estar associada a alguns tipos de neoplasias e à mortalidade na população em geral. OBJETIVO: O referido trabalho buscou verificar os fatores associados à autoavaliação positiva da saúde em jovens adultos e ativos. MATERIAIS E MÉTODOS: A amostra deste estudo, de corte transversal, foi composta por 695 rapazes, retirados da população de jovens, com 18 anos de idade, em processo de alistamento militar. As variáveis do estudo foram: classe socioeconômica, estado civil, escolaridade, trabalho, tabagismo, consumo de álcool, estresse, prática de atividade física habitual e autoavaliação da saúde. Para análise dos dados realizaram-se os testes da razão de verossimilhança e regressão logística hierarquizada. RESULTADOS: Verificou-se associação entre autoavaliação positiva da saúde com maior escolaridade (OR = 3,38; IC 95%; 1,83-6,23) e não tabagismo (OR = 3,42; IC 95%; 1,69-6,92). Na análise ajustada para as variáveis sociodemográficas - escolaridade (mais que oito anos de estudo) (OR = 3,05; IC 95%; 1,63-5,73) e não ser fumante (OR = 3,03; IC 95%; 1,47-6,25), permaneceram associados à autoavaliação positiva da saúde. CONCLUSÃO: Os achados apontam para a necessidade de enfatizar outros fatores comportamentais associados à autoavaliação da saúde em jovens do sexo masculino.

INTRODUCTION: Self-reported positive health seems to be associated with various factors in the general population. Among active men, the association with such traits seems to be unclear. OBJECTIVE: This work has aimed to verify the factors associated with self-reported positive health in active young men. Material and METHODS: cross sectional research was carried out with a sample of 695 male conscripts, taken from the male population (age of 18 years), in the mandatory army enlisting process. The study variables were: socioeconomic status, marital status, education, work, smoking, alcohol consumption, stress, regular physical activity practice and self-reported health. In order to analyze the data likelihood, ratio tests were calculated and hierarchical logistic regression analysis applied. RESULTS: Association between self-reported positive health and high education - eight or more years (OR=3.38; IC 95%; 1.83-6.23), and non- smoking (OR=3.42; IC 95%; 1.69-6.92) was found. When the analysis was adjusted to social-demographic variables, high education (OR=3.05; IC 95%; 1.63-5.73), and non-smoking (OR=3.03; IC 95%; 1.47-6.25) kept on the model being associated with self-reported positive health. CONCLUSION: Such findings suggest the need to develop intervention strategies in an intersectional and multi-professional manner in the public health departments, related to risk behavior and social factors.

Este trabalho teve por objetivo verificar a associação entre fatores da condição socioeconômica com a inatividade física, comportamento sedentário e excesso de peso corporal em jovens. A amostra deste estudo foi composta por 758 sujeitos, retirada da população de jovens em condição de alistamento militar. As variáveis independentes do estudo foram: classe econômica, estado civil, escolaridade, ser trabalhador. A inatividade física, exposição ao comportamento sedentário e excesso de peso corporal foram utilizados como variáveis dependentes. Após ajuste, verificou-se associação entre a inatividade física e os indicadores de condição econômica escolaridade (RP = 1,42; IC 95% = 1,00-2,01) e ser trabalhador (RP = 1,67; IC = 95% 1,21-2,32). O excesso de peso corporal associou-se com as classes econômicas "C" (RP = 2,60; IC 95% = 1,40-4,84) e "D/E" (RP = 2,08; IC 95% = 1,26-3,44). Conclui-se que jovens com maior escolaridade e que não trabalhavam foram mais inativos fisicamente e que os que estavam em menor condição econômica mostraram-se com excesso de peso corporal.

The purpose of this study was to verify the association between socioeconomic factors and physical activity, sedentary behavior and overweight in youth. The sample was composed of 758 subjects from the population of initial military service . The independent variables were: socioeconomic class, marital status, educational level, and be worker. Physical Inactivity, exposures to sedentary behavior and be overweight were used as dependent variables. After adjustment, it was verified an association between physical inactivity and the indicators of economic status: education level (PR = 1.42, 95% CI = 1.00 to 2.01) and be worker (PR = 1.67, CI95% =1.21 to 2.32). Overweight was associated with economic class "C" (PR = 2.60, 95% CI = 1.40 to 4.84) and "D/E" (PR = 2.08, CI95% = 1.26 to 3.44). It is concluded that youth with higher education level and not employed were more physically inactive. It was showed association between lower economic status and excess body weight.

Este estudio tiene como objetivo verificar la asociación entre los factores socioeconómicos con inactividad física, el sedentarismo y el sobrepeso en los jóvenes. La muestra de este estudio consistió de 758 sujetos, la retirada de la población joven en situación de alistamiento militar. Las variables independientes del estudio fueron: clase económica, estado civil, educación, ser trabajador. La inactividad física, el sedentarismo y la exposición al exceso de peso se utilizaron como la variable dependiente.
