Disease control and management

Globally, the main contributors to morbidity and mortality are chronic conditions, including cardiovascular disease and diabetes. Chronic disease is costly and partially avoidable, with around 60% of deaths and nearly 50% of the global disease burden attributable to these conditions. By 2020, chronic illnesses will likely be the leading cause of disability worldwide. Existing healthcare systems that focus on acute episodic health conditions, both national and international, cannot address the worldwide transition to chronic illness; nor are they appropriate for the ongoing care and management of those already dealing with chronic diseases. As such, chronic disease management requires integrated approaches that incorporate interventions targeted at both individuals and populations, and emphasise the shared risk factors of different conditions. International and Australian strategic planning documents articulate similar elements to manage chronic disease, including the need for aligning sectoral policies for health, forming partnerships, and engaging communities in decision-making. Infectious diseases are also a common and significant contributor to ill health throughout the world. In many countries, this impact has been minimised by the combined efforts of preventative health measures and improved treatment methods. However, in low-income countries, infectious diseases remain the dominant cause of death and disability. The World Health Organization (WHO) estimates that infectious diseases (including respiratory infections) still account for around 23% (or around 14 million) of all deaths each year, and result in over 4.6 billion episodes of diarrhoeal disease and 243 million cases of malaria each year (Lozano et al. 2012, WHO 2009). In addition to the high level of mortality, infectious diseases disable many hundreds of millions of people each year, mainly in developing countries, with the global burden of disease from infectious diseases estimated to be around 300 million DALYs (disability-adjusted life years) (WHO 2012). The aim of this chapter is to outline the impact that infectious diseases and chronic diseases have on the health of the community, describe the public health strategies used to reduce the burden of those diseases, and discuss the historic and emerging disease risks to public health. This chapter examines the comprehensive approaches implemented to prevent both chronic and infectious diseases, and to manage and care for communities with these conditions.

Determinants of institutional care at older ages in Finland

Väitöskirjassa selvitettiin ikäihmisten laitoshoitoon siirtymisen todennäköisyyttä ja sen taustoja kansainvälisesti ainutlaatuisen rekisteriaineiston avulla. Selvitettäviä asioita olivat eri sairauksien, sosioekonomisten tekijöiden, puolison olemassaolon ja leskeksi jäämisen yhteys laitoshoitoon siirtymiseen yli 65-vuotiailla suomalaisilla. Tutkimuksessa havaittiin, että dementia, Parkinsonin tauti, aivohalvaus, masennusoireet ja muut mielenterveysongelmat, lonkkamurtuma sekä diabetes lisäsivät ikäihmisten todennäköisyyttä siirtyä laitoshoitoon yli 50 prosentilla, kun muut sairaudet ja sosiodemografiset tekijät oli otettu huomioon. Korkeat tulot vähensivät laitoshoidon todennäköisyyttä, kun taas puutteellinen asuminen (ilman peseytymistiloja tai keskus- tai sähkölämmitystä) sekä erittäin puutteellinen asuminen (ilman lämmintä vettä, vesijohtoa, viemäriä tai vesivessaa) lisäsivät todennäkösyyttä, kun muut sosiodemografiset tekijät, sairaudet ja asuinalue oli huomioitu. Kerrostalon hissittömyys ei ollut yhteydessä laitoshoidon todennäköisyyteen. Todennäköisyys siirtyä laitoshoitoon oli jostain syystä korkeampaa niillä ikäihmisillä, jotka asuivat vuokralla ja matalampaa omakotitalossa asuvilla ja niillä, joilla oli auto. Puolison olemassaolo vähensi ja leskeksi jääminen lisäsi laitoshoidon todennäköisyyttä huomattavasti. Todennäköisyys oli erityisen suuri, yli kolminkertainen, kun puolison kuolemasta oli kulunut enintään kuukausi verrattuna niihin, joiden puoliso oli elossa. Todennäköisyys laski, kun puolison kuolemasta kului aikaa. Miesten ja naisten tulokset olivat samansuuntaisia. Korkeat tulot tai koulutus eivät suojanneet riskiltä joutua laitoshoitoon puolison kuoltua. Puolison kuolema näyttää lisäävän hoidon tarvetta, kun kotona ei ole enää puolisoa tukemassa ja huolehtimassa kodin askareista. Laitoshoidon tarve vähenee, jos ja kun lesket ajan kuluessa oppivat elämään yksin. Toisaalta tutkimustulokset saattavat viitata myös siihen, että kaikkein huonokuntoisimmat lesket, jotka eivät pärjää yksin asuessaan, siirtyvät laitoshoitoon hyvin nopeasti puolison kuoltua. Tutkimuksessa oli mukana yhteensä yli 280 000 yli 65-vuotiasta henkilöä, joiden pitkäaikaiseen laitoshoitoon siirtymistä seurattiin tammikuusta 1998 syyskuuhun 2003. Laitoshoidoksi määriteltiin terveyskeskuksissa, sairaaloissa ja vanhainkodeissa tai vastaavissa yksiköissä tapahtuva pitkäaikainen hoito, joka kesti yli 90 vuorokautta tai oli vahvistettu pitkäaikaishoidon päätöksellä. Tutkimuksessa käytetty aineisto koottiin väestörekistereistä, sosiaali- ja terveydenhuollon rekistereistä ja lääkerekistereistä.

Not in all Walks of Life? : Social Differences in Suicide Mortality

In Finland, the suicide mortality trend has been decreasing during the last decade and a half, yet suicide was the fourth most common cause of death among both Finnish men and women aged 15 64 years in 2006. However, suicide does not occur equally among population sub-groups. Two notable social factors that position people at different risk of suicide are socioeconomic and employment status: those with low education, employed in manual occupations, having low income and those who are unemployed have been found to have an elevated suicide risk. The purpose of this study was to provide a systematic analysis of these social differences in suicide mortality in Finland. Besides studying socioeconomic trends and differences in suicide according to age and sex, different indicators for socioeconomic status were used simultaneously, taking account of their pathways and mutual associations while also paying attention to confounding and mediatory effects of living arrangements and employment status. Register data obtained from Statistics Finland were used in this study. In some analyses suicides were divided into two groups according to contributory causes of death: the first group consisted of suicide deaths that had alcohol intoxication as one of the contributory causes, and the other group is comprised of all other suicide deaths. Methods included Poisson and Cox regression models. Despite the decrease in suicide mortality trend, social differences still exist. Low occupation-based social class proved to be an important determinant of suicide risk among both men and women, but the strong independent effect of education on alcohol-associated suicide indicates that the roots of these differences are probably established in early adulthood when educational qualifications are obtained and health-behavioural patterns set. High relative suicide mortality among the unemployed during times of economic boom suggests that selective processes may be responsible for some of the employment status differences in suicide. However, long-term unemployment seems to have causal effects on suicide, which, especially among men, partly stem from low income. In conclusion, the results in this study suggest that education, occupation-based social class and employment status have causal effects on suicide risk, but to some extent selection into low education and unemployment are also involved in the explanations for excess suicide mortality among the socially deprived. It is also conceivable that alcohol use is to some extent behind social differences in suicide. In addition to those with low education, manual workers and the unemployed, young people, whose health-related behaviour is still to be adopted, would most probably benefit from suicide prevention programmes.

Sosiaalipalveluja kaikille ja kaiken ikää? : Tutkimus suomalaisten mielipiteistä ja kokemuksista sosiaalipalveluista sekä niiden suhteesta legitimiteettiin

This research analyses opinions on the system of social welfare services from the point of view of clients and the public in general in Finland. The approach is quantitative, drawing on theories of the welfare-state tradition. The data used comes from the comprehensive Welfare and Services in Finland survey compiled by STAKES. While previous research on the welfare state has predominantly focused on surveying public opinion on social protection, this research focuses on social welfare services. The main focus of this research is on publicly funded care provided by municipal social welfare services. In this research, social welfare services include child day care, services for people with disabilities, home-help services, counselling by social workers and social assistance. The research considered in particular whether the clients or the population has different opinions towards social welfare services or social benefits. In addition, the research partly covers areas of informal care provided by family and friends. The research material consisted of the STAKES Welfare and Services in Finland survey. The data was compiled in 2004 and 2006 by Statistics Finland. The research comprises five articles. Additional data have been extracted from social welfare statistics and registers. Multiple approaches were applied in the survey on welfare and services the methods in this research included interviews by phone and mail, and register data. The sample size was 5 810 people in 2004 and 5 798 in 2006. The response rates were 82.7% and 83.7%, respectively. The results indicate that a large majority (90%) of the Finnish population is of the opinion that the public sector should bear the main responsibility for organising social and health services. The system of social welfare services and its personnel have strong public support 73% and 80% respectively. However, new and even negative tones have emerged in the Finnish debate on social welfare services. Women are increasingly critical of the performance of social welfare services and the level of social protection. Furthermore, this study shows that women more often than men wish to see an increase in the amount of privately organised social welfare services. Another group critical of the performance of social welfare services are pensioners. People who had used social welfare services were more critical than those who had not used them. Thus, the severest criticism was received from the groups who use and gain most from public services and benefits. However, the education and income variables identified in earlier studies no longer formed a significant dividing line, although people with higher education tend to foster a more positive view of the performance of social welfare services as well as the level of social protection. Income differences did not bear any significance, that is, belonging to a high or low income group was not a determining factor in the attitude towards social welfare services or social benefits. According to the research, family and friends still form an informal yet significant support network in people's everyday lives, and its importance has not been diminished by services provided by the welfare state. The Finnish public considers child day care the most reliable form of social welfare services. Indeed, child day care has become the most universal sector of our system of social welfare services. Other services that instil confidence included counselling by social workers and services for people with disabilities. On the other hand, social assistance and home-help services received negative feedback. The negative views were based on a number of arguments. One argument contends that the home-help service system, which was originally intended for universal use, is crumbling. The preventive role of home-help services has been reduced. These results mirror the increasingly popular opinion that social welfare services are not produced for all those who need them, but to an increasing extent for a select few of them. Municipalities are struggling with their finances and this, combined with negative publicity, has damaged the public's trust in some municipal social welfare services. A welfare state never achieves a stable condition, but must develop over time, as the world around it changes. Following the 1990's recession, we are now in a position where we can start to develop a system that responds to the needs of the next generation. Study results indicating new areas of dissatisfaction reflect the need to develop and improve the services provided. It is also increasingly essential that social welfare services pay attention to the opinions of clients and the public. Should the gap between opinions and actual activities increase, the legitimacy of the whole system would be questioned. Currently, the vast majority of Finns consider the system of social welfare services adequate, which provides us with the continuity required to maintain and improve client-oriented and reasonably priced social welfare services. Paying attention to the signals given by clients and the general public, and reacting to them accordingly, will also secure the development and legitimacy of the system in the future.

Arrested Drunk Drivers : Trends, social background, recidivism and mortality

The aim of this study was to examine the trends, incidence and recidivism of drunken driving during a 20-year period (1988 - 2007) using the data on all suspected drunken driving in this period. Furthermore, the association between social background and drunken driving, and the mortality of drunk drivers were studied by using administrative register data provided by Statistics Finland. The study was completely register-based. In 1989 - 1991, every year 30,000 drivers were suspected of drunken driving, but the number fell to less than 20,000 by 1994, during the economic recession. The changes in the arrest incidence of the youngest age groups were especially pronounced, most of all in the age group of 18 - 19-year olds. Even though the incidence among youth decreased dramatically, their incidence rate was still twice that of the general population aged 15 - 84 years. Drunken driving was associated with a poor social background among youth and working-aged men and women. For example, a low level of education, unemployment, divorce, and parental factors in youth were associated with a higher risk of being arrested for drunken driving. While a low income was related to more drunken driving among working-aged people, the effect among young persons was the opposite. Every third drunk driver got rearrested during a 15-year period, whereas the estimated rearrest rate was 44%. Findings of drugs only or in combination with alcohol increased the risk of rearrest. The highest rearrest rates were seen among drivers who were under the influence of amphetamines or cannabis. Also male gender, young age, high blood alcohol concentration, and arrest during weekdays and in the daytime predicted rearrest. When compared to the general population, arrested drunk drivers had significant excess mortality. The greatest relative differences were seen in alcohol-related causes of death (including alcohol diseases and alcohol poisoning), accidents, suicides and violence. Also mortality due to other than alcohol-related diseases was elevated among drunk drivers. Drunken driving was associated with multiple factors linked to traffic safety, health and social problems. Social marginalization may expose a person to harmful use of alcohol and drunken driving, and the associations are seen already among the youth. Recidivism is common among drunk drivers, and driving under the influence of illicit and/or medicinal drugs is likely to indicate worse substance abuse problems, judging from the high rearrest rates. High alcohol-related mortality in this population shows that drunken driving is clearly an indicator of alcohol abuse. More effective measures of preventing alcohol-related harms are needed, than merely preventing convicted drunk drivers from driving again.

Mother-Infant Antibodies to Pneumococcal Polysaccharides and Proteins : Transfer and Persistence of Maternal Antibodies and Development of Vaccine-Induced and Naturally Acquired Antibodies in Infants

Symptomless nasopharyngeal carriage of Streptococcus pneumoniae (pneumococcus) is very common in young children. Occasionally the carriage proceeds into mild mucosal diseases, such as sinusitis or acute otitis media, or into serious life-threatening diseases, such as pneumonia, sepsis or meningitis. Each year, up to one million children less than five years of age worldwide die of invasive pneumococcal diseases (IPD). Especially in the low-income countries IPD is a leading health problem in infants; 75% of all IPD cases occur before one year of age. This stresses the need of increased protection against pneumococcus in infancy. Anti-pneumococcal antibodies form an important component in the defence against pneumococcal infection. Maternal immunisation and early infant immunisation are two possible ways by which potentially protective antibody concentrations against pneumococci could be achieved in early infancy. The aim of this thesis is to increase the knowledge of antibody mediated protection against pneumococcal disease in infants and young children. We investigated the transfer of maternal anti-pneumococcal antibodies from Filipino mothers to their infants, the persistence of the transferred antibodies in the infants, the immunogenicity of the 23-valent pneumococcal polysaccharide vaccine (PPV) in infants and the response of the children to a second dose of PPV at three years of age. We also investigated the development of antibodies to pneumococcal protein antigens in relation to culture-confirmed pneumococcal carriage in infants. Serum samples were collected from the mothers, the umbilical cords and from the infants at young age as well as at three years of age. The samples were used to determine the antibody concentrations to pneumococcal serotypes 1, 5, 6B, 14, 18C and 19F, as well as to the pneumococcal proteins PspA, PsaA, Ply, PspC, PhtD, PhtDC and LytC by the enzyme immunoassay. The findings of the present study confirm previously obtained results and add to the global knowledge of responses to PPV in young children. Immunising pregnant women with PPV provides the infants with increased concentrations of pneumococcal polysaccharide antibodies. Of the six serotypes examined, serotypes 1 and 5 were immunogenic already in infants. At three years of age, the children responded well to the second dose of PPV suggesting that maternal and early infant immunisations might not induce hyporesponsiveness to polysaccharide antigens after subsequent immunisations. The anti-protein antibody findings provide useful information for the development of pneumococcal protein vaccines. All six proteins studied were immunogenic in infancy and the development of anti-protein antibodies started early in life in relation to pneumococcal carriage.

Social and material deprivation among youth in Finland : causes, consequences, and coping.

Background: Social and material deprivation is associated with poor health, decreased subjective well-being, and limited opportunities for personal development. To date, little is known about the lived experiences of Finnish low-income youths and the general purpose of this study is to fill this gap. Despite the extensive research on socioeconomic income disparities, only a few scholars have addressed the question of how low socioeconomic position is experienced by disadvantaged people themselves. Little is known about the everyday social processes that lead to decreased well-being of economically and socially disadvantaged citizens. Data: The study is based on the data of 65 autobiographical essays written by Finnish low-income youths aged 14-29 (M=23.51, SD=3.95). The research data were originally collected in a Finnish nationwide writing contest “Arkipäivän kokemuksia köyhyydestä” [Everyday Experiences of Poverty] between June and September of 2006. The contest was partaken by 850 Finnish writers. Methods and key concepts: Autobiographical narratives (N=65) of low-income youths were analyzed based on grounded theory methodology (GTM). The analysis was not built on specific pre-conceived categorizations; it was guided by the paradigm model and so-called “sensitizing concepts”. The concepts this study utilized were based on the research literature on socioeconomic inequalities, resilience, and coping. Socioeconomic inequalities refer to unequal distribution of resources, such as income, social status, and health, between social groups. The concept of resilience refers to an individual’s capacity to cope despite existing risk factors and conditions that are harmful to health and well-being. Coping strategies can be understood as ways by which a person tries to cope with psychological stress in a situation where internal or externals demands exceed one’s resources. The ways to cope are cognitive or behavioral efforts by which individual tries to relieve the stress and gain new resources. Lack of material and social resources is associated with increased exposure to health-related stressors during the life-course. Aims: The first aim of this study is to illustrate how youths with low socioeconomic status perceive the causes and consequences of their social and material deprivation. The second aim is to describe what kind of coping strategies youths employ to cope in their everyday life. The third aim is to build an integrative conceptual framework based on the relationships between causes, consequences, and individual coping strategies associated with deprivation. The analysis was carried out through systematic coding and orderly treatment of the data based on the grounded theory methodology. Results: Finnish low-income youths attributed the primary causes of deprivation to their family background, current socioeconomic status, sudden life changes, and contextual factors. Material and social deprivation was associated with various kinds of negative psychological, social, and material consequences. Youths used a variety of coping strategies that were identified as psychological, social, material, and functional-behavioral. Finally, a conceptual framework was formulated to link the findings together. In the discussion, the results were compared and contrasted to the existing research literature. The main references of the study were: Coping: Aldwin (2007); Lazarus & Folkman (1984); Hobfoll (1989, 2001, 2002).

Framework for morphometric classification of cells in imaging flow cytometry

Imaging flow cytometry is an emerging technology that combines the statistical power of flow cytometry with spatial and quantitative morphology of digital microscopy. It allows high-throughput imaging of cells with good spatial resolution, while they are in flow. This paper proposes a general framework for the processing/classification of cells imaged using imaging flow cytometer. Each cell is localized by finding an accurate cell contour. Then, features reflecting cell size, circularity and complexity are extracted for the classification using SVM. Unlike the conventional iterative, semi-automatic segmentation algorithms such as active contour, we propose a noniterative, fully automatic graph-based cell localization. In order to evaluate the performance of the proposed framework, we have successfully classified unstained label-free leukaemia cell-lines MOLT, K562 and HL60 from video streams captured using custom fabricated cost-effective microfluidics-based imaging flow cytometer. The proposed system is a significant development in the direction of building a cost-effective cell analysis platform that would facilitate affordable mass screening camps looking cellular morphology for disease diagnosis. Lay description In this article, we propose a novel framework for processing the raw data generated using microfluidics based imaging flow cytometers. Microfluidics microscopy or microfluidics based imaging flow cytometry (mIFC) is a recent microscopy paradigm, that combines the statistical power of flow cytometry with spatial and quantitative morphology of digital microscopy, which allows us imaging cells while they are in flow. In comparison to the conventional slide-based imaging systems, mIFC is a nascent technology enabling high throughput imaging of cells and is yet to take the form of a clinical diagnostic tool. The proposed framework process the raw data generated by the mIFC systems. The framework incorporates several steps: beginning from pre-processing of the raw video frames to enhance the contents of the cell, localising the cell by a novel, fully automatic, non-iterative graph based algorithm, extraction of different quantitative morphological parameters and subsequent classification of cells. In order to evaluate the performance of the proposed framework, we have successfully classified unstained label-free leukaemia cell-lines MOLT, K562 and HL60 from video streams captured using cost-effective microfluidics based imaging flow cytometer. The cell lines of HL60, K562 and MOLT were obtained from ATCC (American Type Culture Collection) and are separately cultured in the lab. Thus, each culture contains cells from its own category alone and thereby provides the ground truth. Each cell is localised by finding a closed cell contour by defining a directed, weighted graph from the Canny edge images of the cell such that the closed contour lies along the shortest weighted path surrounding the centroid of the cell from a starting point on a good curve segment to an immediate endpoint. Once the cell is localised, morphological features reflecting size, shape and complexity of the cells are extracted and used to develop a support vector machine based classification system. We could classify the cell-lines with good accuracy and the results were quite consistent across different cross validation experiments. We hope that imaging flow cytometers equipped with the proposed framework for image processing would enable cost-effective, automated and reliable disease screening in over-loaded facilities, which cannot afford to hire skilled personnel in large numbers. Such platforms would potentially facilitate screening camps in low income group countries; thereby transforming the current health care paradigms by enabling rapid, automated diagnosis for diseases like cancer.

Academic spin-offs incubation strategies: the case of the Andalusian region

[EN] The objective of this paper is to analyze the incubation strategies developed in the universities of Andalusia, a relatively low-income region of Spain, to promote the creation of university spin-offs. These strategies are also compared to the incubation models noted in the literature. The performance of the university spin-offs created and its relation to the incubation strategies developed by the university are also analysed. The analysis is based on data from a survey of nine public universities that carry out strategies for the promotion of university spin-offs. The result of the analysis shows that university spin-off incubation strategies in Andalusia present specific characteristics not covered by certain models that are well-known in the literature on innovation. Then, a new stage in the process of the university spin-off incubation is proposed. We consider it to be a pre-strategic stage to the academic spin-off incubation strategies. The analysis also finds certain environmental factors associated to those spin-offs promoted by Andalusian universities that achieve the highest level of performance. This result suggests that previous to making any decision involving investment into developing incubation strategies, universities should gauge whether they have sufficient resources and the possibilities of connecting with a Technology Park.

Mecanismos federais de coordenação de políticas sociais e capacidades institucionais locais : o caso do Programa Bolsa Família

Este trabalho analisa o Programa Bolsa Família (PBF), tratando de sua evolução ao longo do governo Lula, tanto no que diz respeito ao seu escopo quanto a seu desenho institucional e as alterações que foi sofrendo em seus objetivos. Tendo em vista a natureza federativa do Estado brasileiro, o objetivo do trabalho é mostrar os desafios enfrentados pelo poder central para garantir a implementação homogênea de um programa nacional de transferência condicionada de renda a ser gerido pelos municípios. Para tanto, são analisados, de um lado, os recursos institucionais e as estratégias de que dispunha o governo federal para alcançar os seus objetivos para o PBF, e de outro, os resultados e a dinâmica da gestão municipal do programa em dois grandes centros urbanos, São Paulo e Salvador. São analisadas informações relativas ao desempenho nacional do programa e também referentes à implementação municipal do PBF nos casos escolhidos, por meio de dados de surveys realizados com a população de baixa renda e de entrevistas semi-estruturadas com gestores municipais do programa nessas duas cidades. A tese identifica os mecanismos que asseguram o crescente poder de coordenação do governo federal no sentido de fazer com que suas principais diretrizes para o programa sejam de fato implementadas no plano municipal. Mostra também que o processo de implementação do PBF é afetado não só por seu desenho institucional, definido no plano federal, mas também pelas diferentes capacidades institucionais disponíveis no plano local recursos humanos, capacidade de gestão e articulação entre diversos serviços e políticas, infra-estrutura disponível, entre outros aspectos e pelos diferentes interesses políticos na maior ou menor coordenação dos programas locais de transferência com o programa nacional. Finalmente, o trabalho examina ainda os limites e possibilidades para a articulação do PBF com uma política mais ampla de assistência social.

Efectos macroeconómicos de la progresividad en los sistemas de seguridad social: una aplicación al caso de los Estados Unidos

[ES] Este trabajo estudia los potenciales efectos macroeconómicos de una reforma que aumente la progresividad del sistema de Seguridad Social de los Estados Unidos de América. Condicionados por los supuestos del modelo, los resultados abogan por un aumento en el bienestar social con un determinado aumento de la progresividad. Esto es debido a que la redistribución total de la renta de los más pudientes a los que cuentan con menos recursos origina un contexto de menor bienestar social. Además, los resultados respaldan la validez del tipo de cotización como herramienta para ajustar el nivel de progresividad del sistema y rechazan la tasa de reemplazo de la pensión como mecanismo para conseguir dicho fin.

Incidência de tuberculose por município, Brasil 2001-2003: uma abordagem sobre o programa de controle e fatores determinantes da doença

Esta pesquisa avaliou a situação da tuberculose no Brasil, no período de 2001 a 2003, segundo indicadores do processo de operacionalização do Programa Nacional de Controle de Tuberculose (PNCT), e estimou os efeitos de fatores determinantes da taxa de incidência da doença. Para a avaliação utilizou-se a análise de cluster não-hierárquica, visando agrupar os municípios brasileiros de acordo com a morbidade por tuberculose (TB) e AIDS, e pelo desempenho do PNCT. Estes clusters foram mapeados, comparando-se a distribuição nos municípios, em regiões metropolitanas, municípios prioritários, e segundo o tamanho da população. O qui-quadrado de Pearson foi utilizado para testar associação nas categorias. A modelagem longitudinal multinível foi usada para identificar e estimar os efeitos dos determinantes da doença. Os agregados foram: anos, municípios e regiões metropolitanas. O modelo foi de intercepto e inclinação aleatória. Foram retidas as variáveis capazes de diminuir a variância dos níveis, pois, desta forma, explicam a variabilidade hierárquica da doença. Incluiu-se renda, densidade populacional, proporção de cura, taxa de incidência de AIDS e as grandes regiões brasileiras. A avaliação mostrou que a situação epidemiológica preocupante ocorreu nos municípios com Baixa TB e Alta AIDS, e Alta TB e AIDS. O cluster de Muito baixa TB e AIDS concentrou 50% dos municípios, o que pode configurar problemas de notificação. São 6 clusters de desempenho do programa. Bom e Bom com baixo DOTS predominando nos municípios pequenos, não prioritários e fora das regiões metropolitanas. No desempenho Moderado houve maior proporção de municípios prioritários. Clusters Regular e Fraco concentraram 10% dos municípios, com abandono de tratamento elevado e cura muito baixa. O cluster Muito Fraco caracterizou-se pela falta de dados nos indicadores de desempenho. O modelo multinível identificou a AIDS como fator impactante na tuberculose, anteriormente não encontrado em outros estudos; a interação entre renda e AIDS, e importante contribuição das regiões metropolitanas na distribuição da tuberculose, que se manifesta heterogeneamente nas grandes regiões do país. A análise discriminou municípios, e mostrou não haver associação entre maior morbidade e melhor desempenho do PNCT, retratando inadequação da vigilância à realidade epidemiológica do Brasil. O programa necessita ser reforçado, no sentido de considerar a AIDS ao estabelecer suas estratégias de controle. Ademais, os aspectos de baixa renda da população e densidade populacional, já analisados em diversas pesquisas, também se manifestaram de forma importante nestes resultados.

Representação social dos políticos em uma comunidade

Buscamos com este trabalho investigar a representação social que moradores de comunidades de baixa renda têm em relação aos políticos. A Teoria das Representações Sociais de Moscovici fundamenta o estudo, que conta ainda com o Modelo Estrutural de Abric, conceitos da Lógica Natural de Grize e procedimentos básicos de estatística descritiva para a análise dos dados. O instrumento da pesquisa foi subdividido em quatro partes, dedicadas às coletas de dados de caracterização socioeconômica dos sujeitos, evocações livres a partir do termo indutor "político", respostas às perguntas do questionário semi-aberto e relatos de casos que envolvessem políticos nas entrevistas abertas. Com as evocações, procuramos determinar os prováveis elementos centrais e periféricos da representação social; com as entrevistas, verificamos relações de causalidade entre os temas mais recorrentes nos discursos. Com a análise, as evocações indicaram um núcleo central com elementos que estão consistentemente em torno da noção de "corrupto": "ladrão", "mentiroso" e "safado". A estrutura da representação social parece, a despeito disso, revelar a possibilidade de uma visão embrionária, por parte dos sujeitos, onde os aspectos mais sociais se sobrepõe à percepção mais pessoal e individualista a respeito dos políticos. As respostas ao questionário denotaram interesse e desconhecimento sobre a atividade política, além de um pensamento marcadamente crítico em relação à questão da representatividade: os políticos são vistos como individualistas, defensores de seus próprios interesses e não acessíveis ao eleitor. As entrevistas revelaram seis temas gerais ("são corruptos", "só querem o voto", "fazem falsas promessas", "manipulam as pessoas", "somem depois das eleições" e "não resolvem os problemas") que foram organizados em uma estrutura, formada pelos seus significados articulados entre si como causa ou efeito, para descrição da representação. Esta, parte de uma condição implícita, a corrupção e o individualismo, passa pelas falsas promessas e pela manipulação das pessoas, e termina na incompetência, na não resolução dos problemas.

Fatores associados a transtornos mentais comuns e desejo de engravidar em gestantes adolescentes

De acordo com a Organização Mundial da Saúde, o período da adolescência é aquele compreendido entre os 10 e os 19 anos de idade, a população de adolescentes é crescente e um em cada cinco indivíduos encontra-se nessa faixa etária. Anualmente, 60 em cada mil jovens se tornam mães, o que faz da gravidez na adolescência tema de interesse por parte de pesquisadores de todo o mundo. No município do Rio de Janeiro, observou-se o acompanhamento da tendência nacional de aumento de gravidez precoce, com maior variação positiva encontrada na faixa etária de 10 a 14 anos. O objetivo no Artigo I: Determinar a prevalência de transtornos mentais comuns (TMC) em uma população de adolescentes grávidas e avaliar sua associação com características da gravidez e fatores socioeconômicos, demográficos e de rede social de apoio. Artigo II: Determinar a prevalência de desejo de engravidar em uma população de gestantes adolescente, verificar possíveis associações com fatores socioeconômicos, demográficos e de rede social de apoio e avaliar o papel da idade como modificador de efeito dessas associações. Foram utilizados nos Artigos I e II o método de estudo seccional de base ambulatorial realizado com 232 adolescentes grávidas, em qualquer trimestre gestacional, regularmente atendidas nos serviços de pré-natal de dois hospitais públicos especializados do município do Rio de Janeiro, de maio a outubro de 2007. Foi utilizado questionário autopreenchível para a avaliação das características da gravidez, rede social de apoio, idade, renda, escolaridade, abandono escolar, situação conjugal, raça/cor e trabalho. As análises dos TMC foram conduzidas através do GHQ-12. Os resultados no Artigo I foram, a prevalência de TMC foi de 45,3%. O modelo final ajustado mostrou associação com TMC para as seguintes variáveis: renda familiar menor que três salários mínimos (RP = 2,32; IC 95% 1,15 - 4,67), não ter apoio familiar (RP = 2,18; IC 95% 1,69-2,81), não ter amigas para conversar (RP = 1,48; IC 95% 1,13-1,92) e não ter religião (RP = 1,72; IC 95% 1,25 - 2,36). No Artigo II, foram a prevalência de desejo de engravidar entre as gestantes adolescentes foi de 46,2%. No modelo final ajustado, as variáveis que apresentaram razões de prevalência (RP) estatisticamente significantes para associação com desejo de engravidar foram: ser casada ou viver em união estável (RP = 1,80; IC 95% 1,27-2,56), não ter amigas ou amigos com quem conversar (RP = 1,48; IC 95% 1,15-1,90). Adolescentes entre 12 e 16 anos e cursando o primeiro grau desejavam menos a gravidez (RP = 0,57; IC 95% 0,38- 0,88). Artigo I: Os resultados encontrados mostram que, frente à forte associação entre TMC e gravidez em adolescentes, temos a necessidade de implementação de políticas públicas que busquem minimizar os danos decorrentes das gestações em adolescentes, através da promoção de programas que incentivem a participação familiar no processo de aceitação da gravidez, bem como propiciando espaços para discussão, onde essas jovens possam ser ouvidas e orientadas. Artigo II: Os resultados deste estudo comprovam que a gravidez na adolescência não é necessariamente indesejada. Assim, fatores como viver em união estável e não ter amigas(os) para conversar aumentam o desejo de engravidar. Por outro lado, ter entre 12 e 16 anos e ainda estar no primeiro grau diminui este desejo. Tais achados podem ajudar os profissionais de saúde que lidam com essa faixa etária a identificar possíveis situações de risco para a gravidez e assim direcionar sua orientação de forma precisa e adequada.
