Analýza programů primární prevence v libereckém kraji / The analysis of the primary prevention programmes in Liberec region

Tkáčová, Drahuše January 2012 (has links)
Topic of my thesis covers the analysis of programmes, related to primary prevention within the Liberec region. Theoretical part of my thesis comprises the identification of basic terms that are related to the development of socio-pathological phenomena and risk behaviour of children and youth. Furthermore, the thesis depicts the prevention system, which is focused on primary prevention of the risk behaviour. An important part of the thesis is the primary prevention as a part of the upbringing process. The theoretical part of my thesis ends with a chapter that is dealing with the community planning process of villages. By means of an empiric investigation, practical part of the thesis analyses the situation within the primary prevention at elementary schools, information on the number of providers and programmes for primary prevention are investigated in the thesis as well. Another important output lies within the needs and attitudes of the villages in the given region.

Prevenção de deiscência da aponeurose com uso profilático de tela pré-aponeurótica em laparotomias de emergência: ensaio clínico randomizado / Prevention of fascial dehiscence with prophylactic use of onlay mesh in emergency laparotomies: a randomized clinical trial

Lima, Helber Vidal Gadelha 11 June 2019 (has links)
INTRODUÇÃO: Laparotomias de emergência apresentam alto risco de complicações e evoluem com deiscência da aponeurose (DA) em até 14,9% dos casos. O uso profilático de tela no fechamento da parede abdominal reduz a incidência de hérnia incisional após cirurgias eletivas, sem aumento significativo de morbidade. Porém, não há estudos que comprovem seu benefício na prevenção de DA e seu uso ainda é controverso em laparotomias de emergência e em cirurgias contaminadas ou infectadas. OBJETIVOS: Avaliar se o uso profilático de tela no fechamento da parede abdominal reduz a incidência de DA em pacientes submetidos a laparotomia de emergência, assim como a morbidade de sua aplicação. MÉTODOS: Foi realizado um ensaio clínico randomizado no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo. Indivíduos com alto risco para DA e indicação de laparotomia mediana de emergência foram randomizados em grupos de sutura (síntese contínua da aponeurose com fio de polidioxanona e agulha de 36 mm, com objetivo de alcançar a relação entre os comprimentos do fio e da incisão igual ou superior a quatro) ou de tela profilática (síntese da aponeurose como no grupo de sutura, reforçada com tela pré-aponeurótica de polipropileno). Alto risco foi definido segundo escore de risco pré-operatório de Rotterdam adaptado. A equipe cirúrgica permaneceu cega no intraoperatório (randomização somente após síntese completa da aponeurose). RESULTADOS: De junho de 2015 a fevereiro de 2018, foram randomizados 145 pacientes, dos quais 30 foram excluídos (20,7%) por óbito ou reoperação nos primeiros 30 dias, não relacionados a intervenção do estudo; 52 foram alocados no grupo de sutura e 63 no de tela profilática. Ambos foram equivalentes quanto a dados demográficos e características clínicas, exceto idade, cuja média foi maior no grupo de sutura (66,1 anos vs 61,0 anos, p = 0,03). Os pacientes foram classificados como ASA III ou IV em 44 (38,3%) casos. Dentre as operações, 49 (42,6%) foram contaminadas ou infectadas, 63 (54,8%) envolveram a realização de ostomia e 89 (77,4%) foram cirurgias colorretais. Os tempos de internação hospitalar e em UTI foram semelhantes. O tempo operatório médio foi 50,8 minutos mais longo no grupo de tela profilática (p = 0,01). A DA ocorreu em sete casos do grupo de sutura (13,5%) e em nenhum do grupo de tela profilática (p = 0,003). Não houve diferença estatística em relação ao número de participantes que apresentou ocorrências de sítio cirúrgico (SSO) [15 (28,8%) vs 27 (42,9%), p = 0,12] ou ocorrências de sítio cirúrgico que necessitaram de intervenção (SSOPI) [9 (17,3%) vs 14 (22,2%), p = 0,51]. Porém, algumas SSO foram mais frequentes no grupo de tela profilática: seroma [3 (5,8%) vs 12 (19,0%), p = 0,03], infecção de sítio cirúrgico (SSI) [4 (7,7%) vs 13 (20,6%), p = 0,05] e deiscência superficial de ferida operatória [3 (5,8%) vs 15 (23,8%), p = 0,008]. Sete casos do grupo de tela profilática tiveram deiscência superficial com exposição de tela e foram tratados com curativos locais e cicatrização por segunda intenção, havendo resolução completa em menos de 90 dias. Nenhum caso necessitou de remoção completa da tela. Das SSO do grupo de tela profilática, 92,3% tiveram resolução espontânea ou com intervenções à beira-leito, o que aconteceu em 73,3% do grupo de sutura. CONCLUSÕES: A tela profilática pré-aponeurótica em laparotomias de emergência é segura e evita DA, com morbidade aceitável, em 30 dias / INTRODUCTION: Emergency laparotomies have a high risk of complication with reports of fascial dehiscence (FD) in up to 14.9% of cases. The use of onlay mesh in the closure of abdominal wall reduces incidence of incisional hernia after elective surgeries without increased morbidity. However, there are no studies demonstrating its benefit in FD prevention and its use is controversial in emergency laparotomies and in contaminated or infected surgeries. OBJECTIVES: To evaluate whether the use of onlay mesh in the closure of the abdominal wall reduces the incidence of FD in patients submitted to emergency laparotomy, as well as the morbidity of its application. METHODS: A randomized clinical trial was conducted at the Hospital das Clínicas, Faculdade de Medicina, Universidade de São Paulo. Patients at high risk for FD and indication of emergency midline laparotomy were randomized either to the suture group (running suture with polidioxanone thread and 36 mm needle size, aiming to achieve suture-to-wound length ratio of 4:1) or to the prophylactic mesh group (fascial closure as in the suture group, reinforced with polypropylene onlay mesh). High risk was defined according to the adapted Rotterdam preoperative risk model. The surgical team was blinded to the groups during the intraoperative period (randomization occurred only after complete fascial suture). RESULTS: From June 2015 to February 2018, 145 patients were randomized, 30 of whom were excluded (20.7%) because of death or reoperation, not related to the mesh procedure, in the first 30 days; 52 were allocated in the suture group and 63 in the prophylactic mesh group. Both groups were equivalent for demographic data and clinical characteristics, except for age, whose mean was higher in the suture group (66.1 years vs 61.0 years, p = 0.03). Patients were classified as ASA III or IV in 44 (38.3%) cases. Among the operations, 49 (42.6%) were contaminated or infected, 63 (54,8%) involved ostomy formation and 89 (77.4%) were colorectal surgeries. Hospital length of stay (LOS) and intensive care unit LOS were similar. Mean operative time was 50.8 minutes longer in the prophylactic mesh group (p = 0.01). FD occurred in seven cases of the suture group (13.5%) and none in the prophylactic mesh group (p = 0.003). There was no statistical difference between the groups regarding the number of patients with surgical site occurrence (SSO) [15 (28.8%) vs 27 (42.9%), p = 0.12], or surgical site occurrences that required procedural interventions (SSOPI) [9 (17.3%) vs 14 (22.2%), p = 0.51]. However, some SSO were more frequent in the prophylactic mesh group: seroma [3 (5.8%) vs 12 (19.0%), p = 0.03], surgical site infection (SSI) [4 (7, 7%) vs 13 (20.6%), p = 0.05] and superficial wound dehiscence [3 (5.8%) vs 15 (23.8%), p = 0.008)]. Seven cases of the prophylactic mesh group had superficial wound dehiscence with mesh exposure, treated with local dressings and healing by second intention, with complete resolution in less than 90 days. No case required complete removal of mesh. Of the SSO in the prophylactic mesh group, 92.3% had spontaneous resolution or with bedside interventions; the same occurred in 73.3% of the suture group. CONCLUSIONS: The onlay prophylactic mesh in emergency laparotomy is safe and avoids FD, with acceptable morbidity in 30 days

Risco de câncer e comportamentos preventivos: a persuasão como uma estratégia de intervenção / Cancer risk and preventive behaviors: persuasion as an intervention strategy

Tonani, Marcela 11 September 2007 (has links)
O câncer configura-se como um problema de saúde pública e seu controle depende essencialmente de ações nas áreas da promoção da saúde, proteção específica e do diagnóstico precoce da doença. A efetividade das intervenções designadas para seu controle pode contar com o auxílio do processo de persuasão empregado. O presente estudo buscou avaliar o grau de risco para apresentação de câncer contemplando os fatores de risco pertinentes, bem como, avaliar a presença e as características da persuasão na comunicação para prevenção e detecção precoce de câncer. Trata-se de um estudo observacional, com caráter transversal, onde foram empregados dois instrumentos para o alcance dos objetivos; a população abordada foi de um bairro da cidade de Ribeirão Preto/SP. Constatou-se que os altos riscos foram para os cânceres de cólon/reto, cérvico e de endométrio; e moderados riscos para estes acrescidos de pulmão e mama. Quanto à persuasão, observou-se que houve o desencadeamento das informações acerca do câncer, no entanto estas não conseguiram manter-se efetivas por longos períodos; também não se identificou o reforço dessas informações. Portanto, diante do risco de câncer e dos comportamentos preventivos levantados, considera-se que a persuasão é uma estratégia útil para diminuição desses riscos e, de incentivo e manutenção de comportamentos preventivos; porém, ela deve conter todas as etapas do processo a fim de que não se perca a oportunidade de gerar comportamentos preventivos ou de detecção precoce. / The cancer is configured as a problem of public health and its control depends essentially on action in the areas of the promotion of the health, specific protection and of the precocious diagnosis of the illness. The effectiveness of interventions assigned for its control can count with auxiliare of the process of persuasion employed. This study aims to evaluate the risk level of developing cancer, considering the pertinent risk factors, and the presence of persuasion and characteristics in the communication regarding cancer prevention and early detection. It is an observational study, conducted on 110 inhabitants of a neighborhood in the city of Ribeirao Preto, Sao Paulo, Brazil. It was confirmed there are high risks for colon/rectum, cervical, and endometrial cancer; and moderate risks for these and also lung and breast cancer. In terms of persuasion, it was observed that cancer information was spread but was not sustained for long periods. Moreover, there was no reinforcement. In view of cancer risk and the identified preventive behaviors, persuasion is considered a useful strategy to reduce these risks as well as to encourage and sustain preventive behaviors, however it must contain all the stages of these process for doesn\'t lose the chance to develope preventive behaviors or precocious detection.

Rizikové chování na sociálních sítích a jeho prevence u žáků základních a středních škol / Risky Behaviour of Elementary and Secondary School Pupils on Social Networks and Its Prevention

Botlík, Tomáš January 2019 (has links)
The following final thesis "Risky behaviour of lower and upper secondary school students on social networks and its prevention" introduces the topic of primary prevention of cyberbullying and security on social networks with regards to their current use by lower and upper secondary school students. Another aim of the thesis is to ascertain which forms of risky social behaviour the target groups currently encounter on social networks and to find out the ways in which these social networks are used (the most commonly used applications, the frequency of their use etc.). The thesis doesn't focus solely on social networks, it also addresses the subject matter of critical thinking since one of the problematic aspects of using social networks by young people is the fact that they use multiple sources of information without further verification. Following the results of the research, short-term activities of primary prevention for both target groups are proposed. They aim to encourage the development of critical thinking and media studies. The proposed activities can be further incorporated into long-term prevention programmes. They include recommendations for teacher lesson planning and self-study tips. The content of the activities is based on the study of both theoretical and methodological...

Efeitos do consumo de álcool combinado a bebidas energéticas (AmED) entre motoristas de caminhão no Estado de São Paulo: uma combinação de risco / Influence of AmED consumption on traffic risk behaviors among truck drivers of the State of São Paulo: combination of risks

Eckschmidt, Frederico 17 November 2015 (has links)
INTRODUÇÃO O consumo de álcool combinado com bebidas energéticas (AmED) tem se mostrado associado tanto a um padrão pesado de ingestão de bebidas alcoólicas, quanto a comportamentos de risco no trânsito (CRTs) entre jovens adultos. Devido ao grave impacto causado pelas incapacidades e mortes no trânsito serem decorrentes de comportamentos previsíveis e em grande parte evitáveis, o presente estudo procura investigar a influência do consumo de AmED sobre os comportamentos de risco no trânsito entre os motoristas de caminhão. MÉTODOS Dados de uma amostra de profissionais que trafegavam pelas rodovias do Estado de São Paulo entre junho de 2012 e setembro de 2013 (N=535) foram separados em três grupos: (a) os que afirmaram ingerir AmED (n=90), (b) que relataram consumir apenas bebidas alcoólicas (n=326) e (c) o restante da amostra (n=445). Análises bivariadas foram realizadas com os relatos positivos nos últimos 12 meses que antecederam a pesquisa. O nível de significância foi estipulado para um alfa de 5% e, posteriormente, a analise múltipla utilizou a regressão logística. RESULTADOS Comparando os condutores que ingeriram AmED com os que consumiram apenas bebidas alcoólicas, os primeiros tiveram mais chances de possuir idades entre 20 e 24 anos (OR=3,3), de trabalhar como profissional a menos de 5 anos (OR=2,5), apresentaram maiores riscos de dirigir sem cinto de segurança (OR=2,2), em alta velocidade (OR=1,9), ter brigado ou discutido no trânsito (OR=2,1), ter consumido bebidas alcoólicas em um padrão pesado (OR=3,4), bebendo mais doses alcoólicas por ocasião (mediana 5 vs 2 doses, p < 0,008); em maior frequência (OR=1,9), bebendo mais frequentemente no padrão binge drinking (OR=2,3) e consumindo drogas ilícitas em maior frequência (OR=2,3), além de maiores chances de apresentar uma qualidade de sono ruim (OR=1,7). Comparados ao restante da amostra, observou-se que os motoristas de caminhão que ingeriram AmED apresentaram maior risco de dirigir sem cinto de segurança (OR=2,2), em alta velocidade (OR=1,9), alcoolizado (OR=2,6), de brigar ou discutir no trânsito (OR=2,0), apresentaram maiores chances de ingerir mais doses alcoólicas por ocasião (medianas 5 vs 2 doses, p < 0,001), beber mais frequentemente (OR=2,6), inclusive no padrão binge drinking (OR=2,1), também em maior frequência em binge drinking (OR=3,2), consumir álcool em um padrão pesado (OR=3,4) e usar drogas ilícitas (OR=2,6). A regressão logística ajustada por idade indicou que os motoristas que brigaram ou discutiram no trânsito (OR=2,2), que dirigiram sem cinto de segurança (OR=1,9) e que relataram o uso de drogas ilícitas nos últimos 12 meses (OR=2,0) tiveram maiores chances de ter ingerido AmED. CONCLUSÃO O estudo indica uma associação entre a ingestão conjunta de álcool com bebidas energéticas e maiores chances de apresentar CRTs. São necessários investimentos em pesquisas e ações preventivas voltadas para essa população / INTRODUCTION: Consumption of alcohol mixed with energy drinks (AmED) has been shown associated with both a heavy pattern of alcohol intake as well as the traffic risk behaviors (TRB) among young adults. Due to the serious impact caused by disabilities and traffic deaths arising from predictable and largely preventable behaviors, the present study investigates the influence of AmED consumption on traffic risk behaviors among truck drivers. METHODS: Data from a sample of professional driving along the highways of the State of São Paulo (Brazil) between June 2012 and September 2013 (N=535) were divided into three groups: (a) those who reported drinking AmED (n=90), (b) who reported consuming alcohol only (n=326) and (c) the rest of the sample (n=445). Bivariate analyzes were performed with positive reports in the last 12 months preceding the survey. The level of significance was set for an alpha of 5% and, subsequently, it was made a multiple logistic regression analysis. RESULTS: Comparing the drivers who drink AmED with those who consumed only alcohol, the first were more likely to have between 20 and 24 years (OR=3.3), to work as a professional less than five years (OR=2.5), had higher risks of driving without a seat belt (OR=2.2), in high speed (OR=1.9), have a fight or discussion in traffic (OR=2.1), having consumed alcohol in a heavy pattern (OR=3.4), drinking more alcoholic drinks per occasion (median 5 vs 2 doses, p < 0.008); at higher frequency (OR=1.9), more often in binge drinking (OR=2.3), consuming illicit drugs more frequently (OR=2.3), as well as more likely to have a bad quality sleep (OR=1.7). Compared to the rest of the sample, it was found that truck drivers who drink AmED had higher risk of driving without a seat belt (OR=2.2), in high speed (OR=1.9), drunk (OR=2 , 6), to fight or discuss in traffic (OR=2.0), were more likely to consume more alcoholic drinks per occasion (median 5 vs 2 doses, p < 0.001), drinking more often (OR=2.6), including in binge drinking (OR=2.1), also in higher frequency in binge drinking (OR=3.2), consuming alcohol in a heavy pattern (OR=3.4) and use illicit drugs (OR=2 6). Logistic regression adjusted for age indicated that drivers who fought or discussed in traffic (OR = 2.2), which drove without a seat belt (OR = 1.9) and that reported using illicit drugs in the last 12 months (OR = 2.0) had higher chances of having ingested AmED. CONCLUSION: This study indicates an association between the combined intake of alcohol with energy drinks and more likely to have TRBs. Investment is needed in research and preventive actions for this population

Prevenção do dirigir sob efeito de álcool entre estudantes de medicina / Prevention of driving under the influence of alcohol among medical students

Amaral, Ricardo Abrantes do 15 December 2010 (has links)
INTRODUÇÃO: Estudantes universitários apresentam frequências maiores de Dirigir sob efeito do álcool (DEA) e de uso pesado de álcool, assim como de uso nos últimos trinta dias, do que não-estudantes da mesma idade. O objetivo principal deste estudo foi avaliar a efetividade da Intervenção Preventiva (IP) relacionada a esses comportamentos entre estudantes da Faculdade de Medicina da Universidade de São Paulo (FMUSP), da cidade de São Paulo. Este estudo teve como objetivo secundário a tradução e a validação do Questionário baseado na Teoria de Proteção e Motivação (QPMT) para identificar aspectos cognitivos relacionados à avaliação de ameaças e de adaptação quanto ao DEA. MÉTODOS: O QPMT foi traduzido pela equipe técnica de acordo com metodologia da Organização Mundial da Saúde. A etapa de validação (EV), com desenho de estudo transversal, ocorreu entre estudantes do 1º ano da FMUSP/2007. Na Etapa de Intervenção (EI), o desenho do estudo foi o de seguimento. Estudantes do 2º ano da FMUSP/2007 responderam o QPMT e o AUDIT, para avaliação do padrão de consumo de álcool, no tempo zero (T0), no tempo um (T1) logo após as IP, e após um ano, no tempo dois (T2). Em T0, os estudantes foram divididos por sorteio em dois grupos, o grupo de intervenção (GI), que recebeu cinco IP de 15 minutos cada, e grupo controle (GC), que não recebeu IP. RESULTADOS: Todos os estudantes presentes à aula aceitaram participar da EV e responderam os questionários (n = 63). A consistência interna do QPMT foi satisfatória. Na EI, entre 106 estudantes presentes à aula, 91 concordaram em participar e responder os questionários, índice de resposta de 85,9%. Com relação ao DEA 40,5% dos estudantes do GI (n = 17/42) e 38,8% do GC (n = 19/49) referiram o comportamento, em T0 (p = 1,00). A regressão linear múltipla (RLM) demonstrou que, para o GI, aumentos na pontuação do AUDIT e menor percepção de ameaças e de respostas adaptativas para o DEA tiveram efeito preditivo na frequência da intenção de DEA (IDEA). Para o GC, apenas aumentos nas pontuações do AUDIT foram preditivos de maior IDEA. Quando comparados T0 e T2, apenas o GI apresentou redução significativa da média do AUDIT (p = 0,012). Em T2, o DEA foi referido por 45,4% dos estudantes do GI e 63,6% do GC (p = 0,027, comparando o GC entre T0 e T2) e o GI apresentou redução na IDEA. Na RLM em T2, aumentos na pontuação do AUDIT foram preditivos para a IDEA apenas para o GC. O Risco Relativo (RR) para o DEA foi 4,3% maior no GI do que no GC em T0, enquanto na avaliação em T2, o GC teve um RR 28,6% maior. CONCLUSÃO: Reduções no padrão de consumo de álcool e na proporção de IDEA são sugestivos de efetividade da IP em estudantes da FMUSP / INTRODUCTION: College students have higher rates of Driving Under the Influence of alcohol (DUI) and of heavy or last 30-days alcohol consumption than same age non-students. The main objective of this study was to evaluate the effectiveness of a Preventive Intervention (PI) related to these behaviors among university students of the Faculty of Medicine of the University of São Paulo (FMUSP), São Paulo City. A secondary objective was to translate and validate a questionnaire with the Protection Motivation Theory (PMT) in order to recognize cognitive aspects related to threat and coping appraisals process of the DUI behavior METHODS: The PMT was translated by the research team according to the World Health Organization methodology. The Validation Phase (VP), with a cross-sectional design, assessed FMUSP 2007 first-year students. At the Intervention Phase (IP) a follow-up study was conducted. FMUSP 2007 second-year students answered the PMT and the AUDIT, to assess the pattern of alcohol consumption, at baseline, just after PI, and one year later. At baseline, students were randomly selected to an intervention group (IG) or a control group (CG). The IG was submitted to five PI of 15 minutes each. The CG didnt receive any intervention. RESULTS: All of the first-year students attending to a lecture accepted to participate and answered the questionnaires (n = 63). Internal consistency of the PMT was satisfactory. At the IP, from 106 students attending to a lecture, 91 accepted to participate and answered the questionnaires, a response rate of 85.9%. Rates of DUI at baseline were 40.5% for the IG (n = 17/42) and of 38.8% for the CG (n = 19/49, p = 1.00). The multiple linear regression (MLR) showed that for the IG, increasing of AUDIT scores and lower perceptions of threat and coping appraisals for DUI prevention were strong predictors of intention to DUI (IDUI). For the CG increasing of AUDIT scores were predictive of IDUI. Comparison between baseline and one-year follow-up showed that just the IG had significant reductions of the mean AUDIT score (p = 0.012). At follow-up, DUI was reported by 45.4% and by 63.6% of IG and CG students, respectively (p = 0.027 comparing CG results from baseline and follow-up), and the IG showed reductions in IDUI. MLR at follow-up showed that increasing AUDIT scores predicted IDUI just among the CG. Relative Risk (RR) for DUI among IG was 4.3% higher than for the CG at baseline, meanwhile, at follow-up, CG reached a 28.6% higher RR for DUI. CONCLUSION: Reductions in the pattern of alcohol use and in the proportion of IDUI were suggestive of effectiveness of PI among FMUSP students

Efeito da prática de atividade fí­sica na prevenção primária de alterações morfológicas corporais e metabólicas e na qualidade de vida de pessoas vivendo com HIV que iniciam terapia antirretroviral: ensaio clínico pragmático / Effect of physical activity on the primary prevention of body changes and metabolic disturbances in the quality of life of people living with HIV who initiate antiretroviral therapy: a pragmatic clinical trial

Santos, Elisabete Cristina Morandi dos 01 March 2018 (has links)
A terapia antirretroviral (TARV) determinou o aumento da sobrevida das pessoas que vivem com HIV (PVH), porém eventos adversos relacionados à síndrome lipodistrófica, como alterações morfológicas corporais e distúrbios metabólicos vem sendo descritos como fatores de risco cardiovascular nessa população. Objetivo: Avaliar o efeito da prática de atividade física na prevenção primária de alterações morfológicas corporais e metabólicas e na qualidade de vida de PVH que iniciam TARV. Métodos: PVH que estavam em TARV há no máximo quatro meses e não apresentavam alterações metabólicas e morfológicas corporais foram convidadas a participar deste ensaio clínico randomizado pragmático, sendo alocadas aleatoriamente para grupos intervenção ou controle, na proporção de 1:1. A intervenção consistiu de atividade física orientada presencialmente e/ou à distância, com sessões programadas para ocorrer três vezes por semana, sendo duas com treinamento misto/concorrente (cardiorrespiratório e de força) e uma de treinamento simples, cardiorrespiratório, com duração aproximada de 60 minutos, durante seis meses. Foi conduzida no próprio serviço ambulatorial no qual o paciente estava em acompanhamento ou utilizando-se espaços e equipamentos disponíveis em locais públicos (equipamentos de ginástica a céu aberto, arquibancadas, escadas, pista de caminhada e corrida) e elásticos disponibilizados para o projeto. Os desfechos do estudo (atividade física, aptidão cardiorrespiratória, avaliação física, qualidade de vida e dados laboratoriais) foram aferidos à inclusão e depois de concluída a intervenção ou o acompanhamento dos controles. Para testar a hipótese de não modificação do grupo experimental no tempo, em comparação ao grupo controle, um modelo de ANOVA de medidas repetidas não paramétrico foi utilizado com nível de significância de 0,05. Resultados: A população estudada consistiu de 38 PVH, majoritariamente do sexo masculino (87,0%), autodeclarados pretos ou pardos (65,8%), com média de idade de 32,6 anos. À inclusão no estudo apresentavam pouca frequência de atividade física moderada e baixa autoeficácia para a prática de atividades físicas. Ao final do estudo, os níveis de atividade física não apresentaram diferença significativa intergrupos (atividades praticadas na semana precedente, medidas pelo questionário IPAQ e com uso de acelerômetro). Analogamente, não houve diferença significativa intergrupos nas variáveis relacionadas à avaliação física (circunferências da cintura e do abdome, força de preensão manual e de resistência, flexibilidade e aptidão cardiorrespiratória, obtida em teste de ergoespirometria) e na qualidade de vida, avaliada pelo questionário WHOQoLHIV-Bref. Tampouco foram encontradas diferenças significativas na análise intergrupos nas concentrações de glicose em jejum, triglicérides e PCR. Apesar do grupo intervenção ter exibido aumento significativo nas concentrações séricas de LDL-colesterol na análise intergrupos, os valores observados não apresentaram relevância clínica. Conclusões: A realização de ensaio clínico randomizado pragmático para avaliar os efeitos da atividade física na prevenção primária de alterações morfológicas corporais e alterações metabólicas relacionadas à síndrome lipodistrófica, e na qualidade de vida de PVH que iniciam a TARV mostrou-se factível em serviço ambulatorial universitário especializado da cidade de São Paulo. Contudo, não se verificou efeito significativo da intervenção sobre o acúmulo de gordura abdominal, a aptidão cardiorrespiratória, a glicemia de jejum e as concentrações de triglicérides e PCR e sobre a qualidade de vida dos participantes. A baixa autoeficácia para a prática de atividades físicas na população estudada, o reduzido número de participantes e o tempo de intervenção proposto podem ter contribuído para os achados. Para investigação mais aprofundada sobre o tema sugere-se conduzir ensaios clínicos pragmáticos multicêntricos que atentem para as limitações observadas neste estudo / Antiretroviral therapy (ART) has led to increased survival of people living with HIV (PLHIV), but adverse events related to the lipodystrophy syndrome, such as body changes and metabolic disturbances have been described as cardiovascular risk factors in this population. Objective: To evaluate the effect of physical activity on the primary prevention of body changes and metabolic disturbances and in the quality of life of PLHIV who initiate ART. Methods: PLHIV on ART for not more than four months with no body changes and metabolic disturbances were invited to participate in this pragmatic randomized clinical trial. Participants were randomly assigned to intervention or control groups in a 1:1 ratio. The intervention consisted of onsite and/or remotely supervised physical activity sessions, three times a week, two of them with mixed/concurrent training (cardiorespiratory and strength training) and one simple cardiorespiratory training, for approximately 60 minutes, during six months. The intervention was carried out at the clinic where patients were being followed up or using equipment in public open spaces (gym equipment or bleachers, stairs, walking and running lanes) and elastic bands made available for the project. Study outcomes (physical activity, cardiorespiratory fitness, and physical evaluation, quality of life and blood test results) were assessed at admission and after six months. The intervention and control groups were compared over time using a non-parametric repeated-measures ANOVA model, with a significance level of 0.05. Results: The study cohort consisted of 38 PLHIV, mostly males (87.0%), self-reportedly black or mulatto (65.8%), with a mean age of 32.6 years. At inclusion they presented low frequency of moderate physical activity and low self-efficacy for physical activity. At the end of follow-up physical activity levels did not show significant intergroup differences (activities practiced in the previous week, measured by the IPAQ questionnaire and accelerometer). Likewise, no significant intergroup differences were seen in variables related to physical evaluation (waist and abdomen circumferences, hand grip and resistance strength, flexibility and cardiorespiratory fitness) and to quality of life assessed by WHOQoLHIV-Bref. In addition, the intervention yielded no significant differences on fasting glucose, triglyceride and CRP concentrations in intergroup analysis. Although the intervention group presented a significant increase in serum LDL-cholesterol concentrations in intergroup analysis, this was not considered clinically relevant. Conclusions: A pragmatic randomized clinical trial to evaluate the effect of physical activity on the primary prevention of body changes and metabolic disturbances related to the lipodystrophic syndrome and in the quality of life of PLHIV who initiate ART was feasible at a university outpatient clinic in the city of São Paulo. However, no significant effect of the intervention was demonstrated on abdominal fat, cardiorespiratory fitness, fasting glucose, triglyceride and CRP concentrations and on the participants\' quality of life. The low self-efficacy for physical activities in the study population, the reduced number of participants and the proposed duration may have contributed to the findings. For further investigation on the subject, multicenter pragmatic clinical trials are warranted, taking the limitations observed in this study into account

Freitas, Fernanda Lins e. January 2008 (has links)
Orientador: Tânia Moron saes Braga / Banca: Raul Aragão Martins / Banca: Alessandra Turini Bolsoni Silva / Resumo: O tabagismo define-se como uma doença epidêmica, pediátrica, crônica e contagiosa, relacionando-se a uma das maiores causas mundiais de morbi-mortalidade. O contexto escolar apresenta-se como principal local para o desenvolvimento de medidas preventivas de caráter primário, tendo como alvo a população pré-adolescente. O treino de habilidades sociais pertinentes à exposição tabágica, bem como o uso da instrução verbal na aquisição de conhecimentos relativos aos malefícios do cigarro parecem indicar fatores de proteção à iniciação ao tabagismo. Esta dissertação caracteriza pré-adolescentes da 5ª série de duas escolas públicas e seus familiares quanto aos conhecimentos prévios sobre tabagismo, perfil sócio-econômico e história tabagística, e avalia, por meio de delineamento de pesquisa quase-experimental, a eficiência de uma intervenção educativa de prevenção primária ao tabagismo nas escolas participantes, sendo uma caracterizada como grupo Experimental (n=27) e a outra, grupo Controle (n=34). Foram realizadas avaliações com os pré-adolescentes distribuídos por sexo, antes e após a intervenção por meio de um Instrumento de Avaliação de Conhecimento e pela medida de auto-relato do Inventário Multimídia de Habilidades Sociais para Crianças (IMHSC-Del-Prette). A intervenção educativa constituiu-se de 8 sessões, com duas horas de duração cada, às quais ocorreram com freqüência de duas vezes por semana. As sessões foram intercaladas quanto ao conteúdo abordado, sendo as sessões ímpares de caráter informativo (utilização da técnica da instrução verbal) e, as pares, de caráter vivencial (realização do treino de desempenhos sociais adequados para lidar com exposição tabágica). Os resultados obtidos indicam diferença estatisticamente significativa entre os grupos Controle e Experimental nas fases...

The school context is presented as the main place for the development of preventive measures that are primary, targeting the preadolescent population. The social skills training relevant to tobacco exposure and the use of verbal instruction in the acquisition of knowledge concerning the harm caused by cigarette seem to prevent smoking initiation. This dissertation characterize preadolescents in the 5th grade of two public schools and their families as to previous knowledge about smoking, social-economic profile and smoking history, and evaluates, through design of quasi-experimental research, the efficiency of an educational intervention for primary prevention of smoking among the participating schools, being characterized as Experimental group (n = 27) and the other, Control group (n = 34). Evaluations were conducted with preadolescents distributed by sex, before and after an intervention through a Knowledge Assessment Instrument and through the self-report measure of Multimedia Social Skills Inventory for Children (MUSSIC - Del-Prette). The educational intervention consisted of 8 sessions, with the duration of two hours each, which occurred twice a week. The sessions were interspersed according to the discussed subject, the odd sessions had an informative character (using the verbal instruction technique) and, the even ones, living character (realization of social performance training appropriate to dealing with smoking exposure). The results show a statistically significant difference between the Experimental and Control groups in pre and pos-intervention stages of the Knowledge Assessment measures, but did not show significant difference between these groups in the self-report of social behavior frequency of MUSSIC in the different studied...

Videotrénink interakcí a možnost jeho využití v programech primární prevence / Video Interaction Guidance and possibilities of its use at primary prevention programms

Jelínková, Hana January 2012 (has links)
Video Interaction Guidance (VIG) or Video Home Training (VHT) was introduced to the Czech Republic in 1993. SPIN is a provider of education, training and supervision, a non- governmental organization dedicated to VIG/VHT in Czech Republic. The method was conceived in the Netherlands in the 80's, the country from where it is still spread to the whole world, especially to Europe. The method's theory is broadly based on developmental psychology theories, ethnology, learning theories and theories of communication. Initially, the VHT was used as an intervention method focused on families with children, later it entered the fields of education and other professional help and was known as VIG. This Diploma Thesis brings essential information about the VHT/VIG Method, its theoretical basis and applications. The thesis also deals with the programmes of primary prevention in the Czech Republic and Europe. The theoretical part concludes with a description of field where VHT/VIG can be used in primary prevention programmes. In the qualitative study, we describe case studies of seven lecturers of primary prevention who undertook the method VHT/VIG. The data were acquired in the process of observation (participative observation and video-analysis), via semi-structured interviews and questionnaires. We attempted...

Beyond the established risk factors of myocardial infarction : lifestyle factors and novel biomarkers

Wennberg, Patrik January 2009 (has links)
Age, male sex, hypertension, smoking, diabetes, dyslipidaemia, and obesity are considered as established risk factors for cardiovascular diseases. Several of these established cardiovascular risk factors are strongly influenced by lifestyle. Novel biomarkers from different mechanistic pathways have been associated with cardiovascular risk, but their clinical utility is still uncertain. The overall objective of the thesis was to evaluate the associations between certain lifestyle factors (physical activity and snuff use), biomarkers reflecting the haemostatic and the inflammatory systems and risk of a future first-ever myocardial infarction.  A prospective incident nested case-control study design was used with a total of 651 cases of myocardial infarction and 2238 matched controls from the population-based Northern Sweden Health and Disease Study.  The effects of commuting activity, occupational and leisure time physical activity on risk of myocardial infarction were studied. A clearly increased risk of myocardial infarction was found for car commuting compared to active commuting (walking, cycling or going by bus). High versus low leisure time physical activity was associated with decreased risk of myocardial infarction. Low occupational physical activity was associated with risk of myocardial infarction in men.  The risk of myocardial infarction or sudden cardiac death was studied in male snuff users compared to non-tobacco users. No increased risk was found for myocardial infarction or sudden cardiac death among snuff users without a previous history of smoking. However, for sudden cardiac death the study did not have statistical power to detect small differences in risk.  Plasma levels of haemostatic markers have previously shown to be associated with risk of myocardial infarction, but as haemostatic markers are also acute-phase reactants, it is not clear if their association with myocardial infarction is independent of inflammatory markers. In the present study, the haemostatic markers D-dimer, von Willebrand factor (VWF), tissue plasminogen activator (t-PA), and tissue plasminogen activator/plasminogen activator inhibitor-1 complex (t-PA/PAI-1 complex) were associated with risk of myocardial infarction after adjustment for established risk factors and the inflammatory markers C-reactive protein (CRP) and interleukin 6 (IL-6). Furthermore, the addition of eight haemostatic and inflammatory markers could improve the predictive ability for future myocardial infarction beyond that of a model utilizing only established risk factors.  Established risk factors and novel biomarkers were explored as potential mediators of the reduced risk of myocardial infarction related to active commuting. A combination of established risk factors, haemostatic and inflammatory markers appeared to explain a substantial proportion (40%) of the difference in risk for myocardial infarction between active commuters and car commuters. IL-6, t-PA, t-PA/PAI-1 complex, apo B/apo A-1 ratio, and BMI seemed to be the largest potential mediators when tested individually. In conclusion, regular physical activity such as active commuting is associated with reduced risk of a first-ever myocardial infarction. This effect could in part be mediated through a beneficial influence on haemostasis and inflammation, as well as a positive impact on established risk factors. Several haemostatic markers are associated with risk of myocardial infarction independent of established risk factors and inflammatory markers. The combination of haemostatic and inflammatory markers may enhance predictive ability beyond established risk factors. Our findings do not support the hypothesis that snuff use increases the risk of myocardial infarction.
