Measuring socioeconomic position (SEP) in population chronic disease and risk factor surveillance systems is essential for monitoring changes in socioeconomic inequities in health over time. A life course approach in epidemiology considers the long-term effects of physical and social exposures during gestation, childhood, adolescence, and later adult life on health. Previous studies provide evidence that socioeconomic factors at different stages of the life course influence current health status. Measures of SEP during early life to supplement existing indicators of current SEP are required to more adequately explain the contribution of socioeconomic factors to health status and monitor health inequities. The aim of this thesis was to examine how a life course perspective could enhance the monitoring of SEP in chronic disease and risk factor surveillance systems. The thesis reviewed indicators of early life SEP used in previous research, determined indicators of early life SEP that may be useful in South Australian surveillance systems, and examined the association of SEP over the life course and self-rated health in adulthood across different population groups to demonstrate that inclusion of indicators of early life SEP in surveillance systems could allow health inequities to be monitored among socially mobile and stable groups. A variety of indicators, such as parents’ education level and occupation, and financial circumstances and living conditions during childhood, have been used in different study designs in many countries. Indicators of early life SEP used to monitor trends in the health and SEP of populations over time, and to analyse long-term effects of policies on the changing health of populations, need to be feasible to measure retrospectively, and relevant to the historical, geographical and sociocultural context in which the surveillance system is operating. Retrospective recall of various indicators of early life SEP was examined in a telephone survey of a representative South Australian sample of adults. The highest proportions of missing data were observed for maternal grandfather’s occupation, and mother’s and father’s highest education level. Family structure, housing tenure, and family financial situation when the respondent was aged ten, and mother and father’s main occupation had lower item non-response. Respondents with missing data on early life SEP indicators were disadvantaged in terms of current SEP compared to those who provided this information. The differential response to early life SEP questions according to current circumstances has implications for chronic disease surveillance examining the life course impact of socioeconomic disadvantage. While face-to-face surveys are considered the gold standard of interviewing techniques, computer-assisted telephone interviewing is often preferred for cost and convenience. Recall of father’s and mother’s highest education level in the telephone survey was compared to that obtained in a face-to-face interview survey. The proportion of respondents who provided information about their father’s and mother’s highest education level was significantly higher in the face-to-face interview than in the telephone interview. Survey mode, however, did not influence the finding that respondents with missing data for parents’ education were more likely to be socioeconomically disadvantaged. Alternative indicators of early life SEP, such as material and financial circumstances, are likely to be more appropriate than parents’ education for life course analyses of health inequities using surveillance data. Questions about family financial situation and housing tenure during childhood and adulthood asked in the cross-sectional telephone survey were used to examine the association of SEP over the life course with self-rated health in adulthood. Disadvantaged SEP during both childhood and adulthood and upward social mobility in financial situation were associated with a reduced prevalence of excellent or very good health, although this relationship varied across gender, rurality, and country of birth groups. Trend data from a chronic disease and risk factor surveillance system indicated that socioeconomic disadvantage in adulthood was associated with poorer self-rated health. The surveillance system, however, does not currently contain any measures of early life SEP. Overlaying the social mobility variables on the surveillance data indicated how inequities in health could be differentiated in greater detail if early life SEP was measured in addition to current SEP. Inclusion of life course SEP measures in surveillance will enable monitoring of health inequities trends among socially mobile and stable groups. Life course measures are an innovative way to supplement other SEP indicators in surveillance systems. Considerable information can be gained with the addition of a few questions. This will provide further insight into the determinants of health and illness and enable improved monitoring of the effects of policies and interventions on health inequities and intergenerational disadvantage. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1367190 / Thesis (Ph.D.) - University of Adelaide, School of Population Health and Clinical Practice, 2009

This ethnography was undertaken in an AIDS hospice with the objective of understanding the functioning of the Centre holistically, including the experiences of the patients and the role of the Centre in the fight against HIV/AIDS. Organisational anthropology in a clinical setting involved gaining entry and rapport with the staff and patients. The methodology included interviewing and observation. The personnel structure and leadership of the Centre were explored, revealing communication, power and management relations that shape the organisational culture. The staff’s attitude towards their jobs and their commitment to assisting those suffering from AIDS revealed the underpinnings of the organisation. The care that patients receive at the Centre was examined along with adoption of the children and the effects of stigmatisation surrounding HIV/AIDS and its impact on patients and their families. The meaning of illness for patients and their sick role as well as the impact of death from HIV/AIDS are exposed. / Anthropology and Archaeology / M.A. (Anthropology)

Adolescent reproductive health services (ARHS) in Gauteng Province are not meeting the reproductive health needs of adolescents. There is also no formalised adolescent/youth policy laid down to assess the quality of care given to adolescents attending these clinics although the policy is currently in the process of being finalised. The purpose of the study therefore was to critically analyse the ARHS in Gauteng Province to determine which adolescents attended the clinics, whether the clinics were accessible and available and whether they provided comprehensive care, gave information and counselling to the adolescent and whether the clinics \\·ere adolescent-friendly. Using the quality care model as the conceptual framework for the study, the following research questions were asked to determine the quality of care in terms of the adolescent's needs at these clinics: Who is the adolescent using ARHS in Gauteng Province') Are the ARHS in Gauteng Province accessible and available to adolescents? Do the ARHS in Gauteng Province provide comprehensive care to adolescents? Are adolescents receiving information and counselling from the ARHS in Gauteng Province? Are the ARHS in Gauteng Province adolescent-friendly? A quantitative cross-sectional exploratory, descriptive research design using a self-administered, researcher­ designed questionnaire was used to collect data from a 203 nonprobability convenient sample, at selected ARHS in Gauteng Province. The analysed data indicated that females in the older age group. ie 18-19 years used the ARHS more than the female adolescents in the younger age group and males. Findings also indicated that the ARHS in Gauteng Province are geographically accessible and available to adolescents. However, there appeared to be a need to extend the days and hours of functioning of the ARHS so as to make them more accessible and available to adolescents. Comprehensive care is not given to adolescents attending ARHS. Adolescent gave contradictory mformation especially with regard to the attitudes of service providers. Recommendations made include management strategies that will attract the adolescent in the younger age group and in particular the male adolescent. This necessitated that service providers at ARHS be equipped with the appropriate information given in an outcome-based format in adolescent care. / Health Studies / D. Litt. et Phil.

Introdução - As doenças respiratórias - asma, doença pulmonar obstrutiva crônica (DPOC), rinite alérgica, sinusite e bronquite aguda - estão entre as principais causas de morbidade, mortalidade e de encargos financeiros para população e para o sistema de saúde. Objetivo - Estimar a prevalência e os fatores associados às doenças respiratórias no município de São Paulo entre 2008 e 2009. Métodos - Estudo transversal, de base populacional, utilizando-se os dados do Inquérito de Saúde no Município de São Paulo 2008 (ISA-Capital 2008), conduzido de 2008 a 2009, com amostra total de 3.271 pessoas de ambos os sexos. As informações foram coletadas por entrevistas domiciliares e os participantes foram selecionados por amostragem probabilística, estratificada por sexo e idade e por conglomerados em dois estágios: setores censitários e domicílios. Associação entre variáveis independentes e dependentes foi verificada na análise bivariada pelo teste 2 com nível de significância de 5 por cento. Foram utilizadas razões de prevalência e intervalos de confiança de 95 por cento e para análise ajustada utilizou-se regressão múltipla de Poisson. Resultados - A prevalência estimada para asma foi 9,1 por cento (IC95 por cento: 7,0-11,7 por cento), DPOC 4,2 por cento (IC95 por cento: 3,1-5,4 por cento), bronquite aguda 7,3 por cento (IC95 por cento: 5,5-9,8 por cento), rinite 22,6 por cento (IC95 por cento: 19,3-26,2 por cento), e para sinusite 15,3 por cento (IC95 por cento: 12,6-18,5 por cento). Após análise ajustada, identificaram-se os seguintes fatores independentemente associados à asma: idade entre 5 e 9 anos, alergia, rinite, problemas de saúde nos últimos 15 dias à entrevista, número menor de cômodos no domicílio e raça/cor da pele preta/parda; à DPOC: idade acima de 60 anos, número de cigarros fumados na vida, cansar-se com facilidade, problemas de saúde nos últimos 15 dias à entrevista e inatividade física; à bronquite aguda: idade entre 5 e 9 anos, alergia, raça/cor da pele preta/parda, número menor de cômodos no domicílio; à rinite: alergia, asma, idade entre 10 e 14 anos e residir em apartamento; à sinusite: alergia, idade entre 15 e 19 anos e obesidade. Conclusões - Os achados do presente estudo apontam para importância da abordagem integrada da asma com rinite e alergias, considerando o conceito da \"via aérea única\". Deve-se considerar idades de maior prevalência de asma (5 a 9 anos) e a cor da pele preta/parta, e ainda, residências com poucos cômodos, devido aglomeração e baixo padrão de moradia; para DPOC, considerando a tendência de seu aumento em virtude da crescente longevidade da população, o diagnóstico precoce e a necessidade de abordagem educacional para cessação do tabagismo e prática de atividades físicas, são importantes para qualidade de vida destes indivíduos e redução do impacto econômico da doença para o sistema de saúde; os fatores associados à bronquite aguda foram presença de alergia, cor da pele preta e parda, e morar em domicílios com poucos cômodos; a rinite alérgica associou-se com asma e residir em apartamento; e a sinusite esteve associada com alergia e obesidade / Introduction - Respiratory diseases - asthma, chronic obstructive pulmonary disease (COPD), allergic rhinitis, sinusitis and acute bronchitis - are among the leading causes of morbidity, mortality and financial burden for the population and the health system in Brazil and worldwide. Objective - To assess the prevalence of and the risk factors for respiratory diseases in São Paulo City, 2008-2009. Methods - A population based cross-sectional study, using data from the São Paulo City Health Survey 2008 (ISA-Capital 2008), conducted in this city along 2008 and 2009, with total sample of 3271 people of both sex. A two stage cluster sampling stratified by sex and age was used. Descriptive statistics were produced and associations were investigated through chi-square tests and prevalence ratios with 95 per cent confidence intervals. Multiple Poisson regression allowed adjustment of effect estimates. Results - The estimated prevalence of asthma was 9.1 per cent (95 per centCI: 7.0-11.7 per cent), COPD 4.2 per cent (95 per centCI: 3.1-5.4 per cent), acute bronchitis 7.3 per cent (95 per centCI: 5.5-9.8 per cent), rhinitis 22.6 per cent (95 per centCI: 19.3-26.2 per cent), and sinusitis 15.3 per cent (95 per centCI: 12.6-18.5 per cent). After adjustment, the following were identified as risk factor to asthma: age, allergy, rhinitis, health problems in the preceding fortnight, homes with few rooms and black and mixed individuals; to COPD: number of cigarettes smoked in life, easily weary, age, health problems in the preceding fortnight and free-time physical activity; to acute bronchitis: age, allergy, black and mixed individuals and homes with few rooms; to rhinitis: allergy, asthma, age and living in flats; and to sinusitis: allergic, age and obesity. Conclusions - The findings of this study indicate the importance of the integrated approach to asthma, rhinitis and allergies, considering the concept of air only, and seek preventive and treatment options that work in a systematic way with respect to these conditions, when present simultaneously. One must consider the age group that has a higher prevalence of asthma, between 5 to 9 years, and black and mixed individuals, and also consider homes with few rooms, because of household crowding and the low standard of housing; for COPD, considering the trend of its increase due to increasing longevity, the need for early diagnosis and educational approach to smoking cessation and physical activity are extremely important for quality of life related to health of these individuals and reducing the economic impact of disease to the health system; factors associated with acute bronchitis were the presence of allergy, black and mixed individuals and those who lived in homes with fewer rooms; rhinitis was associated with asthma and lived in an apartment; and sinusitis was associated with allergies and obesity

INTRODUÇÃO: Existem dúvidas em relação à atividade física (AF) de adultos residentes nas capitais brasileiras e no Distrito Federal no que tange à organização e à execução desta prática. Neste estudo avaliamos a prevalência de AF segundo cada uma das principais diretrizes internacionais que recomendam a AF para a promoção da saúde e exploramos as divergências e consensos na classificação do nível da AF. Avaliamos também a associação entre características sociodemográficas e comportamentais com a prática da AF, como os principais componentes da AF se relacionam na determinação do nível da AF individual e descrevemos o padrão nos portadores de doenças crônicas não transmissíveis (DCNT). METODOLOGIA: Os participantes foram selecionados a partir de dados prévios do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico para as estimativas sobre frequência e distribuição sociodemográfica de fatores de risco e proteção para doenças crônicas nas capitais dos 26 estados brasileiros e no Distrito Federal em 2006. RESULTADOS: Foram elegíveis 54.369 participantes sendo 51,5% classificados como inativos. Houve divergências importantes na graduação da AF pelas principais diretrizes entre os ativos (Kappa = 0,4). A frequência das sessões de AF foi o aspecto que mais contribuiu para a determinação do grau de AF. Recomendação que orienta a frequência diária resultou em uma prevalência menor de AF suficiente. As que orientam volume semanal, sem determinar frequência mínima tiveram as maiores prevalências de AF suficiente. Como decorrência dessa divergência, a prevalência de AF suficiente nas cidades abordadas variou, distinguindo diferentes rankings conforme a recomendação adotada. Cerca de 90% da população ativa realizava sessões com duração entre 30 a 60 minutos e não houve diferença significante entre o grupo que alcançou e o que não alcançou a meta da recomendação. A quase totalidade (90%) dos participantes que alcançou a meta se exercitava três ou mais vezes na semana e 80% dos que não alcançaram a meta se exercitavam entre 1 a 2 vezes na semana. A caminhada, o futebol e a musculação foram as modalidades de exercício físico ou esporte mais frequentes. Encontramos maior prevalência de AF em homens. Negros e amarelos foram fisicamente mais ativos, e a AF diminuiu com a idade, com menor escolaridade e com viuvez. Aproximadamente 65% da população consideraram a sua saúde boa ou excelente e entre os que a consideraram ruim, a maioria estava inativa. O deslocamento ativo e a dieta hipocalórica são características predominantes dos participantes ativos. O tabagismo foi mais frequente entre os inativos e o maior consumo de bebidas alcoólicas ocorreu entre os ativos. As pessoas fisicamente ativas mais frequentemente conheciam instalações próprias para a prática de AF nas proximidades de suas moradias. A inatividade física (62%) foi uma característica destacada entre os participantes portadores de DCNT. No conjunto 70% dos portadores de alguma DCNT não alcançaram a recomendação mínima de AF. CONCLUSÕES: O nível de AF variou muito entre as diretrizes que recomendam a AF. Para uma boa parte desta população, a resposta para a pergunta: \"estou fazendo AF suficiente para a minha saúde?\" Pode ser simultaneamente \"sim\" e \"não\", dependendo do critério da recomendação escolhida. Dentre os insuficientemente ativos, a duração do esforço em cada sessão foi adequada na maioria dos relatos, o que tornou a AF insuficiente foi a baixa frequência. Pensar estratégias que aumentem a frequência semanal para 2 a 3 dias pode elevar o nível de AF para 90% dos insuficientemente ativos / INTRODUCTION: In regards to the organization and implementation of physical activity (PA), there are many doubts related to the PA in adults residing in the capitals of the federation and in the Federal District. This study evaluated the prevalence of PA according to each of the main international guidelines that recommends the practice of PA for good health, explores its divergences, and also the concordances of the PA level classification. We also evaluated the association between the sociodemographic and behavioral characteristics to the practice of PA. More specifically, we focused on how the main components of the PA relates to themselves to determine the level of individual PA and which patterns are present in patients with chronic non-communicable diseases (CNCD). METHODOLOGY: Participants were selected from previous data that the System of Risk Factors Surveillance and Chronic Diseases Protection Telephone Survey, which was used for the estimation of frequency and sociodemographic distribution of risk and protective factors for chronic diseases in the 26 Brazilian state capitals and in the Federal District in 2006. RESULTS: There were 54,369 eligible participants of which 51.5% classified as inactive. There were important divergences in the PA graduation by the main guidelines among the active participants (Kappa = 0.4). The PA session frequency was the main reason that most contributed to the determination of the PA degree. The recommendation, which guides the daily frequency, resulted in the lowest prevalence of enough PA. The recommendations that guide weekly volume without determining minimum frequency had the highest prevalence of enough PA. As a result of this divergence, the prevalence of enough PA in the addressed cities ranged in different distinguishing rankings according to the adopted recommendation. About 90% of the active population performed sessions which lasted between 30 to 60 minutes. From this data, it was evident that there was no significant difference between the group which achieved the recommended PA and the the group which did not achieve the goal of the recommended PA level. Almost all of the participants (90%) who achieved the goal of recommended PA levels exercised three or more times a week and 80% of those who did not reach the goal exercised between 1 to 2 times a week. Trekking, soccer and weightlifting were the most frequent physical exercise modalities or sports performed. We found a higher prevalence of PA in men than in women. Furthermore, the study showed that Blacks and Yellows were more physically active. The amount PA level decreased with age, decreased amongst those with less education and amongst those who were widowed. Approximately 65% of the population considered their health good or excellent and among those who considered it bad, the majority were inactive. Active commuting and hypocaloric diets are predominant characteristics of the active participants. Smoking was more common among the inactive participants but higher alcohol consumption occurred among those that were active. Physically active people frequently knew more suitable facilities for the PA practice near their homes. Physical inactivity (62%) was a prominent characteristic among the participants suffering from CNCD. Overall, 70% of the participants suffering from any CNCD did not attain the minimum recommendations of PA. CONCLUSIONS: The PA levels varied widely among the guidelines that recommend PA. For a large portion of the population, the answer to the question of whether one is doing enough PA for ones health can simultaneously be \"yes\" and \"no\", depending on the criterion of the chosen recommendation. Among the insufficiently active population, the exercise duration in each session was adequate enough in most reports but what made the PA insufficient was the low frequency. Thinking about strategies to increase the weekly frequency for 2 to 3 days can raise the level of PA for 90% of the insufficiently active population

Introdução: O impacto positivo no curto e longo prazos do aleitamento materno exclusivo (AME) na saúde da criança, da mulher que amamenta e para a sociedade estão bem documentados. Apesar da tendência secular crescente do AME no Brasil, a prevalência de 36,6 por cento constatada na última Pesquisa Nacional de Saúde, realizada em 2013, está aquém dos 50 por cento considerados satisfatórios pela Organização Mundial da Saúde. Mediante esse cenário, faz-se importante identificar fatores de risco modificáveis para reduzir a interrupção precoce do AME. Embora o uso de chupeta seja apontado como um dos múltiplos determinantes do AME, não existe consenso sobre o efeito desse hábito na interrupção precoce dessa prática. Objetivo: Analisar a associação entre uso de chupeta e interrupção do AME, bem como a evolução do uso de chupeta e sua influência no AME em menores de 6 meses nas Capitais Brasileiras e no DF, 1999- 2008. Métodos: Foram produzidos 4 manuscritos. O primeiro consistiu de uma revisão sistemática e meta-análise para investigar a associação entre uso de chupeta e interrupção do AME nos menores de 6 meses. Para tanto, realizou-se uma busca ampla em cinco bases de dados (CINAHL, Scopus, Web of Science, LILACS, Medline) sem restrição de data ou idioma de publicação, o que resultou em 1.866 estudos submetidos à critérios de exclusão e inclusão previamente estabelecidos (Protocolo PROSPERO CDR42014014527). O segundo e o terceiro manuscritos utilizaram dados provenientes da I e II Pesquisa de Prevalência de Aleitamento Materno (PPAM) nas Capitais e DF realizadas em 1999 e 2008, respectivamente. Os inquéritos, metodologicamente equivalentes, utilizaram amostras representativas com sorteio em dois estágios. Os questionários foram compostos por questões fechadas relativas ao uso de chupeta e à alimentação da criança no dia anterior à pesquisa. No manuscrito 2, para testar a associação entre o uso de chupeta e o risco de interrupção do AME, foram utilizados modelos de regressão múltipla na amostra agrupada e para cada inquérito, ajustados por covariáveis socioeconômicas, demográficas e biomédicas da mãe da criança. No terceiro manuscrito, calculou-se a fração de impacto potencial (FIP) da influência da variação temporal do uso de chupeta no declínio da interrupção do AME. O manuscrito 4 resultou do aprofundamento na metodologia aplicada no manuscrito anterior, no qual se discute como as estimativas de FIP podem ser utilizadas na análise de mudanças em desfechos populacionais à luz de variações em seus fatores determinantes, tomando como exemplo os dados de AME e uso de chupeta no Brasil. Resultados: O efeito agrupado do uso de chupeta sobre a interrupção do AME em crianças menores de 6 meses dos estudos incluídos na meta-análise foi de OR 2,48 (IC95 por cento =2,16-2,85); entretanto, constatou-se alta heterogeneidade, explicada majoritariamente pelo delineamento do estudo (40,2 por cento ). Os dois ensaios clínicos randomizados incluídos apresentam validade externa limitada e encontraram associação nula; os 44 observacionais, incluindo 20 estudos de coorte prospectivos, encontraram associação consistente (OR=2,28; IC95 por cento =1,78-2,93). Essa associação foi confirmada pela análise agrupada das amostras da I e II PPAM (manuscrito 2), revelando o uso de chupeta como o fator mais fortemente associado à interrupção precoce do AME no Brasil no período de 1999 a 2008 (OR ajustado= 2,77; IC95 por cento =2,63-2,91). Nesse período, no Brasil, houve declínio de 15,2 pontos percentuais na prevalência de interrupção do AME (passando de 74,9 por cento para 59,7 por cento ) e uma redução de aproximadamente 17 pontos percentuais no uso de chupeta (passando de 58,5 por cento para 41,6 por cento ). Um terço do declínio na interrupção precoce do AME pôde ser atribuído à variação temporal do uso de chupeta (manuscrito 3). A redução no uso de chupeta como estratégia de prevenção para interrupção do AME no cenário 1999-2008 apresentou 41 por cento de eficácia potencial, 13,3 por cento de efetividade e 18,5 por cento de eficiência (manuscrito 4). Conclusões: O uso de chupeta é um fator de risco associado à interrupção do AME em crianças menores de 6 meses, sendo um forte determinante no declínio temporal da interrupção precoce dessa prática no Brasil. Como um fator de risco modificável, revelou-se seu potencial na prevenção da interrupção precoce do AME. Estratégias preventivas com abordagem universal e seletiva para redução do uso de chupeta em crianças amamentadas exclusivamente poderiam acelerar a melhoria das taxas da AME no Brasil, rumo às recomendações internacionais / Introduction: The short- and long-term health positive impact that exclusive breastfeeding (EBF) confers to children are well documented. Despite the secular trend for EBF in Brazil has increased, the prevalence of 36 per cent observed in the last national survey conducted in 2013 is still below the 50 per cent considered satisfactory by the World Health Organization. In this scenario, it is important to identify relevant modifiable key risk factors for the premature interruption of EBF. Although pacifier use has been pointed as one of the multiple determinants of exclusive breastfeeding there is no consensus on the effect of this habit in the early interruption of EBF. Objective: To analyze the association between pacifier use and EBF interruption as well as the influence of temporal trends of pacifier use on the EBF in children under 6 months old in Brazilian state capitals and Federal District, 1999-2008. Methods: 4 manuscripts were produced. The first consisted in systematic review and meta-analysis to investigate the association between pacifier use and interruption of exclusive breastfeeding in infants less than 6 months. A wide search in 5 databases (CINAHL, Scopus, Web of Science, LILACS, Medline) from inception through 30 December 2104 without restriction of language yielded 1.866 publications submitted to predetermined inclusion/exclusion criteria peer reviewed (PROSPERO protocol CDR42014014527). In the second and third manuscripts data from 2 waves of infant feeding surveys conducted in 1999 and in 2008 in the Brazilian state capitals and Federal District (I and II PPAM) was used. Methodologically equivalent surveys used representative samples selected based on complex sampling procedures and systematic random selection of children in the queue of each selected immunization center. Questionnaires were composed of closed-ended questions regarding the pacifier use and infant feeding on the day before the survey. In the second manuscript, to find out whether or not pacifier use is an independent risk factor for the EBF interruption were used multivariate regression models in the pooled sample and for each survey wave adjusting for socioeconomic, demographic and biomedical confounders. In the third paper, we calculated the potential impact fraction (IF) of the influence of temporal trends of pacifier use on the decline of EBF interruption. Manuscript 4 resulted from methodological deepening for application of the analysis strategy applied in the previous manuscript, into it we present how estimates of IF that might be used in the analysis of variation in the population outcomes considering shift in its determinants, taking as an example the data about EBF interruption and pacifier in Brazil. Results: The meta-analysis pooled effect was OR 2.48 (CI95 per cent =2.16-2.85) for the association between pacifier use and EBF interruption. The majority heterogeneity was explained by study design (40.2 per cent ). Two RCTs with very limited external validity found a null association, but 44 observational studies, including 20 prospective cohort studies, did find a consistent association between pacifier use and EBF interruption (OR=2.28; CI95 per cent =1.78-2.93). This association was confirmed by the pooled analysis for I and II PPAM (manuscript 2) revealing pacifier use as the strongest risk factor for EBF interruption in Brazil between 1999-2008 (OR adjusted= 2.77; CI95 per cent =2.63-2.91). In this period was observed 15.2 per cent of decline in EBF interruption prevalence (from 74.9 per cent to 59.7 per cent ) and a reduction of approximately 17 per cent in pacifier use (from 58.5 per cent to 41.6 per cent ). A third of the total decline of EBF interruption could be attributed to the temporal trends of pacifier use (manuscript 3). The decrease in the pacifier use as a prevention strategy for EBF interruption in the scenario 1999-2008 showed 41 per cent of potential effectiveness, 13.3 per cent effective and 18.5 per cent efficiency (manuscript 4). Conclusion: Pacifier use is a risk factor associated with EBF interruption, being a strong determinant in the temporal trends of EBF in Brazil. As a modifiable risk factor, the pacifier proved its potential in preventing EBF interruption. Preventive public health strategies with ecological and selective approach to reduce the pacifier use in exclusive breastfed infants could accelerate the improvement of the EBF rates in Brazil, towards the international recommendations
