Atuação sobre os determinantes sociais da saúde em uma iniciativa de Campo Grande, MS - Projeto Viva Seu Bairro / Acting on the social determinants of health on an initiative of Campo Grande-MS: Project Live Your Neighborhood

Gonçalves, Crhistinne Cavalheiro Maymone 09 March 2010 (has links)
Introdução: O Projeto Viva Seu Bairro (PVSB) foi uma iniciativa desenvolvida em seis regiões urbanas da cidade de Campo Grande MS, no período de 2001 a 2004, nas áreas de maior risco social, identificadas pelas equipes de agentes comunitários de saúde e saúde da família. O projeto teve como objetivo a redução das desigualdades sociais por meio de ações que atuaram sobre Determinantes Sociais da Saúde (DSS). Objetivo: A pesquisa buscou conhecer a relação entre o PVSB e os determinantes sociais da saúde, bem como identificar a presença da participação social e da intersetorialidade nas ações desenvolvidas. Material e Métodos: Trata-se de pesquisa de abordagem qualitativa. Foram realizadas entrevistas individuais com gestores da administração municipal e com técnicos da Unidade Técnica Central (UTC), responsável pelo gerenciamento do projeto. Seis grupos focais foram realizados, um em cada região urbana que teve a implementação da iniciativa, com representantes dos Conselhos Regionais Urbanos (CRU). Além disto, foi feita a análise de documentos relacionados ao PVSB. Para a análise dos dados, utilizou-se a análise de conteúdo, por meio da análise temática com a triangulação dos dados obtidos. Resultados: Os resultados da pesquisa apontam uma série de ações que incidiram sobre as condições materiais e psicossociais nas quais as pessoas vivem e trabalham, como proposto pelo modelo adotado nas recomendações do Relatório Final da Comissão Nacional sobre Determinantes Sociais da Saúde (2008). As mais descritas pelos participantes foram as que visaram assegurar saneamento básico, habitação adequada, emprego, serviços de saúde e de educação de qualidade. Verificou-se o protagonismo do setor saúde no desencadeamento da iniciativa. Conclusões: A participação social foi fortalecida na cidade durante e após a iniciativa. Quanto à intersetorialidade, houve a busca por parcerias e o reconhecimento, por parte dos representantes de governo, da necessidade de se implementar redes sociais, o que, no entanto, não se institucionalizou como práticas da administração municipal. A discussão sobre a sustentabilidade ocorreu de modo insuficiente e a avaliação da iniciativa começou um ano e meio após o seu início, o que comprometeu a avaliação de processo. Os participantes da pesquisa reconheceram que o PVSB interferiu na melhoria da qualidade de vida da população local. Conclui-se que o PVSB configurou-se como iniciativa do campo da promoção da saúde, atuou sobre os DSS, fortaleceu os mecanismos de participação nos CRU e buscou mecanismos de ação intersetorial / Introduction - The Project \"Viva Seu Bairro\" (PVSB) was an initiative developed in six urban regions of the city of Campo Grande - MS, from 2001 until 2004, in the areas of greater social risk, identified by the teams of community health and family health agents. The project had as its aim to reduce the social inequalities through actions, which acted on the Social Determinants of Health (SHD). Objective - The research tried to know the relation between PVSB and the Social Determinants of Health, as well as to identify the presence of the social participation and the intersectoriality in the developed actions. Material and Methods - It is about a research of qualitative approach. Individual interviews were performed with managers of the municipal administration and with technicians from Central Technical Unity, responsible for the project administration. Six focal groups were carried out, one in each urban region that had the initiative implementation, with representatives from the Urban Regional Councils. Moreover, an analysis of the documents related to PVSB was done. The Content Analysis was used for the analysis of the data through the thematic analysis and then the triangulation of the obtained data. Results - The results of the research point out a series of actions that occurred to the material and psychosocial conditions in which the people lived and worked, as proposed by the model adopted in the recommendations of the Final Report of the National Commission on Social Determinants of Health (2008). The items most described by the participants were the ones that targeted to assure basic sanitation, appropriate dwelling, employment, health and education services of quality. It was verified the prognostic of the health sector in the breaking of the initiative. Conclusions - The social participation was strengthened in the city during and after the initiative. In relation to the intersectoriality, there was a search for partnerships and the recognition, from the government representatives, of the necessity to implement social nets, which however, was not institutionalized as a practice in the municipal administration. The discussion about the sustainability occurred in an insufficient way and the initiative evaluation started one year and a half after its beginning, which compromised the process of evaluation. The research participants recognized that PVSB interfered in the improvement of the local population life quality. It was concluded that PVSB configured as an initiative in the field of health promotion, acted on SHD, strengthened the mechanisms of participation in the CRU and looked for mechanisms of intersectorial action.

Determinantes da atividade exportadora: uma análise das empresas paulistas / Determinants of export activity: an evaluation of paulista industries

Cava, Patrícia Benites 01 October 2010 (has links)
As importantes mudanças macroeconômicas e a abertura comercial ocorridas na década de 90 tiveram como uma de suas conseqüências a reversão dos superávits comerciais. Esse fato gerou uma série de análises sobre a composição das importações e exportações das firmas brasileiras. Com a abertura comercial, as empresas passaram a investir na racionalização de processos produtivos e gerenciais para se tornarem competitivas. A desvalorização da taxa de câmbio, no final da década de 90, implicou no aumento significativo da parcela exportada pela indústria brasileira e mudanças ocorreram na estratégia competitiva da indústria. A análise destas diferenças e do caminho percorrido por elas contribuem para um melhor mapeamento e discussão das condições competitivas da indústria no mercado internacional. Diante desse contexto, o objetivo do presente trabalho é identificar os principais determinantes da atividade exportadora de indústrias paulistas. Para alcançar o objetivo proposto, utilizou-se dados referentes aos anos de 1996 e 2001 de indústrias paulistas, disponíveis na Pesquisa da Atividade Econômica Paulista (PAEP), realizada pela Fundação Estadual de Análise de Dados (SEADE). Os dois períodos de análise apresentam características distintas no que se refere ao contexto econômico, o que pode ter acarretado na adoção de estratégias competitivas diferentes pelas empresas. Para a estimação dos parâmetros das variáveis explicativas adotou-se os métodos Probit e Logit. Os resultados da pesquisa permitiram identificar o tamanho da empresa, participação estrangeira no capital, idade, importação e inovação tecnológica como determinantes da atividade exportadora das indústrias paulistas. A produtividade do trabalho e a qualificação do trabalho apresentaram resultados distintos para os anos de 1996 e 2001. / Major macroeconomic changes and trade liberalization occurred in the 90s had as one of their consequences the reversal of trade surpluses. This has raised a number of reviews on the composition of imports and exports of Brazilian firms. With the trade liberalization, companies started to invest in the rationalization of production processes and management in order to become competitive. The devaluation of the exchange rate in the end of the 90s, resulted in significant increase in the share exported by the Brazilian industry and changes occurred in the competitive strategy of the industry. The analysis of these differences contributes to a better mapping and discussion of competitive conditions in the industry internationally. In this context, the objective of this study is to identify the main determinants of export activity of Paulistas industries. To achieve the proposed objective, we used data for the years 1996 and 2001 from Paulistas industries, available on the Pesquisa da Atividade Econômica Paulista (PAEP) held by the Fundação Estadual de Análise de Dados (SEADE). These periods have different characteristics with regard to the economic context, which may have led to the adoption of different competitive strategies by companies. For the estimation of the explanatory variables we adopted the methods Probit and Logit. The research results have identified the company size, foreign ownership, age, import and technological innovation as determinants of export activity of the Paulistas industries. The labor productivity and skilled labor showed different results for the years 1996 and 2001.

Direcionadores de valor econômico agregado para instituições financeiras: um estudo dos principais bancos comerciais no Brasil / Determinants of economic value added to financial institutions: a study of main multiple commercial banks in Brazil

Vilela, Dirley Lemos 08 April 2013 (has links)
A eficiência na criação do valor para o acionista é o foco principal das empresas. Uma das formas de se medir essa eficiência é por meio do Valor Econômico Agregado (VEA). Em uma instituição financeira, limitada nesse estudo aos maiores bancos comerciais e múltiplos com ações cotadas na BM&FBOVESPA, os tomadores de decisão também devem buscar essa eficiência. Além disso, a necessidade dos bancos por financiamentos, da mesma forma que nas empresas privadas, exige o atendimento dos requisitos impostos pelo agente que irá fornecer o capital. Nesse sentido, para atender ao acionista, o banco deve promover a agregação de valor. O VEA demonstra essa criação de valor e, para melhor gerenciá-lo, devem ser identificadas, monitoradas e gerenciadas as variáveis que influenciam nessa medida. Diante disso, o presente estudo identificou os principais direcionadores do valor econômico agregado dos maiores bancos comerciais no Brasil: Banco do Brasil, Itaú e Bradesco, utilizando regressão linear múltipla. Por meio da análise dos dados individualizados, referentes ao período de 1996 a 2009, constatou-se que existe um grupo de direcionadores que explicam grande parte das alterações do VEA. Esses direcionadores não foram iguais para os bancos privados e o público em análise, e mesmo entre os privados os resultados não foram coincidentes. Embora algumas variáveis tenham influenciado o VEA, identificou-se que os direcionadores exercem diferentes impactos em cada uma das instituições. Isso indica que a análise deve ser individual e que o tipo de controle também não define as variáveis que mais impactam o VEA. / The efficiency in the creation of the value for the shareholder is the main focus of the companies. One of the ways of measuring this efficiency is through the Economic Value Added (EVA). In a financial institution, limited in this study to the largest and multiple commercial banks and with shares quoted in BM&FBOVESPA, the decision makers should also look for that efficiency. Besides, the need of the banks for financings, in the same way that in the private companies, demands the fulfillment of the requirements imposed by the agent that will supply the capital. In that sense, to assist the shareholder, the bank should promote the aggregation of value. EVA demonstrates this creation of value and, for its better management, the variables that influence in that measure should be identified, monitored and managed. Hence, the present study identified the main determinants of the economical value added from the largest commercial banks in Brazil: Bank of Brazil, Itaú and Bradesco, using multiple linear regression. Through the analyze of the individualized data, regarding the period from 1996 through 2009, it was verified that there is a group of determinants that explain great part of the alterations of EVA. These determinants were not the same for the private and the public banks in analysis, and even among the private ones the results were not coincident. Although some variables have influenced EVA, it has been identified that the determinants provoke different impacts in each one of the institutions. That indicates that the analysis should be individual and that the control type also does not define the variables that impact EVA the most.

Consumption of organic fruits among consumers in Sweden : Theroy of planned behavior and the role of the determinants of intention

Hammarlund, Ludvig, Edhag, Andreas January 2019 (has links)
The increased global consumption has a severe effect on the environment. In order to reduce the environmental impact, there is a need for more environmentally friendly consumption choices. Several studies have confirmed that consumers have a positive attitude towards environmentally friendly products, but that the attitude is, in most cases, not put in to practice. To increase the degree of explanation behind the gap between Swedish consumers intention and behavior regarding the consumption of organic fruits, this study used Ajzen’s (1985) theory of planned behavior. The purpose of this bachelor thesis was to examine if attitude, social norms and experinced behavior control can explain the consumption behavior regarding organic fruits in Sweden. An online-survey with several Likert items was conducted in order to gather data. The respondents were asked about their age, income, education, attitudes, social norms and their experienced behavior control. A correlation test and a multiple regression analysis was conducted in order to see how the determinants of intention correlated with the behavior and how well they could influence the behavior. The results showed that attitude was the determinant that had the strongest correlation (0.522) and contributed the most to the behavior of buying organic fruits. Subjective norm (0.294) and perceived behavior control (0.245) had not as strong correlation as attitude and subjective norm could only influence the behavior to a minimal level. However, it was found that perceived behavior control could influence the behavior. The total rate of explanation for all determinants of intention on the behavior was R2 = 0.568 (56.8%). The conclusions that were made from this study were, firstly, that attitude can influence most of the behavior regarding consumption of organic fruits among Swedish consumers. Secondly, subjective norm can to a minimal degree influence the behavior regarding consumption of organic fruits among Swedish consumers. Thirdly, perceived behavior control can to a minimal degree influence behavior regarding consumption of organic fruits among Swedish consumers. Furthermore, there is a need for more studies who includes behavioral data and more added variables to the TpB model in order to deepen the knowledge about environmentally friendly consumption behaviors.

Le Bitcoin, une monnaie en devenir ? / Bitcoin, the future or a gamble ?

Selmi, Refk 17 May 2019 (has links)
Le Bitcoin jouit d’une histoire très riche malgré son jeune âge. C’est la première cryptomonnaie au monde et la plus répandue. Le Bitcoin repose sur une technologie appelée blockchain capable d’enregistrer des transactions entre deux parties de manière très efficace et vérifiable sans avoir recours à un intermédiaire financier. Cette technologie a propriétés diverses, en particulier la transparence des transactions, l’anonymat, l’absence d’autorité centrale (décentralisation), la limitation de la quantité en circulation… Aussi, comme toute devise, la dynamique du prix du Bitcoin depend-elle de plusieurs facteurs. Nous allons, tout au long de cette dissertation, essayer de mieux comprendre ce phénomène, les principaux facteurs responsables de la variation de sa valeur, les enjeux qu’il soulève, ses propriétés ainsi que ses difficultés à surmonter pour qu’il devienne une véritable monnaie. / In spite of its young age, Bitcoin has a rich history. It is the first and most widespread cryptocurrency in the world. Bitcoin is based on a technology called blockchain that can record transactions between two parties in a very efficient and verifiable way without resorting to a financial intermediary. This technology has various properties, in particular transaction transparency and anonymity, the absence of a central authority (decentralization), the limited and finite supply, among others. Also, like any currency, the Bitcoin’s price dynamics depend on several factors. Throughout this dissertation, we will try to better understand this phenomenon, the main factors responsible for the variation of its value, the issues it raises, its properties as well as its difficulties to overcome so that it becomes a real money.

Determinants of serum perfluoroalkyl acid concentrations in Swedish adolescents and the importance of drinking water as a source of exposure

Nyström, Jennifer January 2019 (has links)
The persistent and toxic perfluoroalkyl acids (PFAAs) are ubiquitously present in the environment and reach humans predominantly via food and drinking water. The aim of the present study was to investigate the effect of low-grade (<10 ng L-1 of single PFAAs) contaminated PFAAs drinking water on serum PFAA concentrations in a representative Swedish adolescent population, and to examine the influence of potential determinants on the variation of the PFAAs serum concentrations. This was done by using multivariate regression analysis on the possible determinants of blood serum PFAA concentrations in 479 Swedish adolescents, 10 to 21 years of age, who had left complete dietary and life style information in 2016-17 in the nation-wide food consumption survey Riksmaten Ungdom. Raw and drinking water samples (DW) from water treatment plants (WTPs) that delivered DW to participants schools were sampled in 2018, analysed for PFAAs, and used for assessing the participants DW PFAA exposure. Maternal education level and maternal birth country, consumption of fish, as well as age and sex were significantly associated with the participants PFAAs serum concentrations. DW concentrations as low as <1 ng L for PFOA and PFHxS, <0.45 ng L-1 for PFNA and <4 ng L-1 for PFOS were significantly associated with increased adolescent serum concentrations of the PFAAs in question, which suggests that low-grade contaminated drinking water is an important exposure route for Swedish adolescents. For risk assessment purposes, it was investigated whether parts of the adolescent population exceeded the serum PFOS and PFOA concentrations corresponding to the current health-based reference intakes as assessed by the European Food Safety Authority (EFSA) and the U.S. Agency for Toxic Substances and Disease Registry (ATSDR). Around 1.7% and 2.7% of participants had PFOS serum concentrations exceeding serum levels used to derive the tolerable daily intake (TDI) (EFSA) and the minimum risk level (MRL) (ATSDR), respectively and a cause for concern was consequently identified. However, the high serum concentrations of participants exceeding the TDI and MRL serum concentrations belong to participants suspected to have been previously exposed to highly contaminated drinking water and not from consuming foods and beverages containing background concentrations of PFAAs.

Análise da evolução diferenciada dos salários e empregos entre as regiões metropolitanas e não metropolitana do estado de São Paulo no período de 1998 a 2012 / Differentiated evolution of wages and employment between metropolitan and non-metropolitan areas of Brazil\'s State of Sao Paulo from 1998 through 2012

Kretzmann, Camila Kraide 15 July 2014 (has links)
A segunda metade do século passado presenciou crescimento populacional e do emprego mais acelerado nos grandes centros urbanos, gerando as metrópoles brasileiras e criando grandes clusters urbanos, como no caso do Estado de São Paulo. No entanto, observa-se que, a partir da segunda metade da década de 1990, nas áreas não metropolitanas os salários têm crescido mais do que nas metropolitanas e há estados em que o volume de emprego cresce mais no seu interior do que na sua região metropolitana. O Estado de São Paulo possui uma região metropolitana federal e mais três regiões metropolitanas estaduais que detinham, em 1998, quase 72% do número de empregos formais do estado, mas este percentual caiu para 69,5% em 2012. Simultaneamente, o diferencial de salário médio real entre o empregado formal das regiões metropolitanas e não metropolitanas caiu 53% no mesmo período. Diante deste contexto, o objetivo da tese foi analisar os determinantes do emprego e do salário das pessoas empregadas formalmente nas regiões metropolitanas e não metropolitanas do Estado de São Paulo, no período de 1998 a 2012, fazendo uso de dados da RAIS, que informa sobre o emprego e o salário médio por município. As equações reduzidas de salário e de emprego foram deduzidas a partir da síntese neoclássica, nas quais as variáveis explicativas abordaram aspectos regionais (alguns de primeira natureza) e econômicos (de segunda natureza), as características pessoais dos trabalhadores, bem como efeitos de inércia. Os testes de autocorrelação espacial I de Moran para os salários e para o emprego sugerem o uso de defasagem espacial nas equações de determinação de salário e emprego. As equações foram estimadas a partir de um painel balanceado de 645 municípios de 1999 a 2011, considerando o método dos momentos generalizados (GMM-SYS) dentro da econometria espacial. Concluiu-se que os coeficientes associados às defasagens espaciais na determinação dos salários são maiores do que os coeficientes relacionados aos efeitos de inércia salarial, já o inverso ocorre para o emprego. Entre as variáveis de primeira natureza, o clima não apresentou impactos estatisticamente significativos sobre os salários e o emprego. O fato de o município ter área de litoral (o que poderia implicar no trabalhador abrir mão de salário em favor de lazer) não impactou os salários, mas gerou mais emprego no município, provavelmente devido aos serviços que atendem aos turistas. Quanto às variáveis de segunda natureza, o PIB per capita teve impacto positivo sobre o salário e o emprego, bem como a participação do setor serviços no PIB do município. Os municípios mais populosos impactaram positivamente o emprego, mas não apresentaram efeitos estatisticamente significativos sobre os salários. Além disso, a variável dummy incluída para separar os municípios não metropolitanos dos demais foi estatisticamente significativa em ambas as equações estimadas, confirmando os resultados de que há maior crescimento do emprego e dos salários no interior do Estado de São Paulo. E, em relação aos efeitos de transbordamento, estes foram de maior magnitude no emprego do que nos salários. / The second half of the last century saw the most rapid population and employment growth toward to large urban centers, generating the Brazilian metropolis and continuous clusters of population, such as the case of São Paulo State. However, since the second half of the 1990s, salaries have grown more into non-metropolitan areas than into metropolitan ones and also there are states in which the number of jobs has growing further inland than into the metropolitan area. The richest Brazilian State of Sao Paulo has one federal metropolitan area and three more state-established metropolitan areas which hold 72% of the formal jobs in 1998, felling to 69.5% in 2012. Simultaneously, the average real wage gap between metropolitan and non-metropolitan employees felt 53% between these two years. In this context, this papers aims to analyze the determinants of employment and wages of the formally employed persons in both metropolitan and non-metropolitan regions of Sao Paulo State, during the time period from 1998 through 2012. Data from Annual Report of Social Information (RAIS in Portuguese), provided by formal enterprises and aggregated by municipalities, is used. A neoclassical-based model for labor supply and demand was built up and two reduced employment and wage equations were deducted, in which the explanatory variables emphasize personal characteristics of the worker, regional and economic features (some of them are classified as first or second nature) as well as including inertia effects in determining the wages and employment. Spatial autocorrelation tests among wages paid in each city and among employment generated in each city were run using the Moran\'s I statistic and the results allowed to use spatial lags for dependent variables at both employment and wage equations. The equations were estimated considering a balanced panel comprised of 645 municipalities over 13 years. Salary and employment equations were run using the generalized method of moments (GMM-SYS) and among the results, we have: (1st) coefficient related to spatial lags in wage determination is larger than the one related to wage inertia effect; however, the opposite was verified for employment. (2nd) Among the variables of first nature, the climate has no statistically significant impact on both wages and employment. The fact that the municipality is located into the coastal area (which could result in a worker to trade off salary in favor of leisure) has no impact on wages, but it creates more jobs in that city, probably due to services that cater to tourists. Among the economics and second nature explanatory variables, the higher the municipal GDP per capita the higher its average salary and formal employment. Also, the higher share of services sector into the municipal GDP, the higher its average salary and more jobs are created. A dummy variable to separate municipalities out of metropolitan areas showed statistically significant at both wage and employment equations, confirming the evidence that both employment and salaries have grown faster in inland areas of the State of São Paulo. The spillover effects were higher for employment than for salaries.

Preferências de elementos da gamification e determinantes do engajamento de discentes de ciências contábeis

Oliveira, André Luiz de Castro January 2018 (has links)
O engajamento dos discentes é um dos assuntos em voga na Educação hoje em dia. Observa-se que os novos alunos possuem uma forma diferente de encarar o processo de aprendizagem, uma vez que o modelo tradicional ainda impõe ao aluno o papel passivo em sala de aula. Nessa perspectiva, o uso da gamification surge como uma proposta de estratégia capaz de auxiliar os professores a atrair os seus alunos, uma vez que a estrutura do gamification possui potencial de engajamento. Seu formato é adequado aos anseios atuais, principalmente quando o assunto é aprendizagem em uma época em que os professores disputam a atenção dos alunos com a tecnologia. Assim, esta pesquisa descreve quais as preferências e os determinantes do engajamento de discentes de Ciências Contábeis em relação aos elementos da gamification. São apresentados os fatores determinantes do engajamento de discentes em relação à aceitação de elementos de gamification. Utiliza-se uma abordagem quanti-qualitativa e descritiva como método para coleta dos dados da pesquisa. O campo de pesquisa explorado foi o curso de Ciências Contábeis da UFRGS, no qual participaram 355 alunos de todo curso (43%). A pesquisa revela que os alunos de graduação são experientes com jogos (quase 95% utilizam jogos digitais) e que eles se envolvem com frequência nessa atividade (54,4% frequência pelo menos mensal). Os resultados permitiram identificar que a percepção dos alunos sobre gamification é positiva: 36,62% disseram que se sentem confortável com a ideia. Além desses, 27% demonstraram animação com essa proposta. Os estudantes indicaram serem favoráveis a um sistema com elementos de gamification no ensino, considerando os seguintes elementos: Pontos, Progressão, Equipes, Medalhas, Perfil e Ajudas. Por fim, esta pesquisa contribui na identificação dos fatores determinantes do engajamento dos discentes em relação à aceitação de elementos de gamification (seção 4.5). Acrescenta ainda informações sobre o relacionamento dos discentes com os jogos, tornando possível encontrar uma linha orientadora que possa auxiliar professores a aplicar com sucesso atividades com gamification. / Engagement of learners is one of the most important topics in Education nowadays. It is observed that the new students have a different way of looking at the learning process, since the traditional model still imposes on the student the passive role in the classroom. In this perspective, the use of gamification appears as a strategy proposal capable of helping teachers to attract their students, since the structure of gamification has potential for engagement. Its format is well suited to current yearnings, especially when it comes to learning in a time when teachers challenge students' attention to technology. Thus, this research describes the preferences and determinants of accounting student engagement in relation to the elements of gamification. The determinants of student engagement in relation to the acceptance of gamification elements are presented. A quantitative-qualitative and descriptive approach is used as a method for collecting research data. The field of research explored was the Accounting Sciences course of UFRGS, in which 355 students from all over the course participated (43%). Research shows that undergraduates are experienced with games (almost 95% use digital games) and that they engage frequently in this activity (54.4% at least monthly frequency). The results allowed to identify that the students' perception about gamification is positive: 36.62% said they feel comfortable with the idea. In addition, 27% demonstrated animation with this proposal. The students indicated that they favor a system with elements of gamification in teaching, considering the following elements: Points, Progression, Teams, Medals, Profile and Helps. Finally, this research contributes to the identification of the determinants of students' engagement in relation to the acceptance of gamification elements (section 4.5). It also adds information about the students' relationship with the games, making it possible to find a guideline that can help teachers to successfully apply gamification activities.

No. of bitstreams: 1 Tese final Karen.pdf: 183529 bytes, checksum: 1ae46938a43097e892ceef4b88e47eeb (MD5) Previous issue date: 2003-02-28 / Objective: To evaluate the prevalence and determinants of common mental disorders (CMD) among adolescents in a southern Brazilian city. Methods: A cross-sectional study, using a multiple stage sampling, was conducted from December 2001 to June 2002. A sample of adolescents aged between 15 and 18 years old, who live in the urban area of Pelotas, a southern Brazilian city, was studied. All male adolescents who obtained scores equal or higher to 5 and female adolescents who scored equal to 6 or more in the twenty questions Self-Report Questionnaire (SRQ) were considered as having CMD. The multivarieted analysis with Poisson regression was performed taking into consideration the hierarchic pattern of variables associated to CMD. Results: 960 adolescents were interviewed. The CMD prevalence was 28,8%. It wasn t verified an association between CMD and age. Adolescents aged 17 years old presented a prevalence 1,37 (95% CI 1,06 1,78) times higher than those 15 years old. Maternal schooling showed that mothers between 5 and 8 years of education had 1,42 (95% CI 1,09 1,85) more prevalence than mothers with more than 8 years of schooling. Adolescents who smoked 16 or more cigaretes per day presented a prevalence 1,66 (95% CI 1,05 2,64) higher than no smokers. Sedentarium people had 1,24 (95% CI 1,01 1,51) more prevalence that non-sedentariun and dissatisfaction with body image 1,47 (95% CI 1,07 2,02). Conclusions: Mother education, smoking habit, sedentariness and body image dissatisfaction are factors related to CMD, which has a high prevalence in the studied population / Objetivo: Descrever a prevalência e os fatores associados a Transtornos Mentais Comuns (TMC) entre adolescentes em uma amostra representativa de base populacional de zona urbana no Sul do Brasil. Métodos: De dezembro de 2001 a junho de 2002, foi realizado um estudo transversal com amostragem em múltiplos estágios, dos adolescentes de 15 a 18 anos, residentes na zona urbana da cidade de Pelotas, extremo sul do Brasil. Foram definidos como tendo transtornos mentais comuns (TMC) todos aqueles adolescentes do sexo masculino com pontuação igual ou superior a 5, e do sexo feminino, com 6 pontos ou mais no Self- Report Questinnaire (SRQ), versão de 20 questões. A análise multivariada com regressão de Poisson foi realizada considerando o modelo hierárquico das variáveis associadas à TMC. Resultados: Foram entrevistados 960 adolescentes. A prevalência TMC foi de 28,8%. Não verificou-se uma associação significativa entre TMC e idade. Os adolescentes de 17 anos, entretanto, apresentaram uma prevalência 1,37 (95% IC 1,06 1,78) vezes maior que os de 15 anos; Mães com escolaridade de 5 a 8 anos têm prevalência 1,42 (95% IC 1,09 1,85) vezes mais que as com mais de oito anos; hábito de fumar, indivíduos consumidores de 16 a 40 cigarros apresentaram prevalência 1,66 (95% IC1,05 2,64) vezes maior que os não fumantes; sujeitos sedentários tem 1,24 (95% IC 1,01 1,51) vezes mais prevalência que não sedentários; e insatisfação com a imagem corporal tem prevalência 1,47 vezes maior (95% IC 1,07 2,02). Conclusões: Escolaridade materna, hábito de fumar, sedentarismo e insatisfação corporal são fatores associados a TMC, que apresentam taxa elevada de prevalência na população estudada
