Abstract The paper develops and illustrates a new multivariate approach to analysing inequity in health care. We measure multiple inequity in health care relating to multiple equity-relevant variables – including income, gender, ethnicity, rurality, insurance status and others – and decompose the contribution of each variable to multiple inequity. Our approach encompasses the standard bivariate approach as a special case in which there is only one equity-relevant variable, such as income. We illustrate through an application to physician visits in Brazil, using data from the Health and Health Care Supplement of the Brazilian National Household Sample Survey, comprising 391,868 individuals in the year 2008. We find that health insurance coverage and urban location both contribute more to multiple inequity than income. We hope this approach will help researchers and analysts shed light on the comparative size and importance of the many different inequities in health care of interest to decision makers, rather than focus narrowly on income-related inequity. Highlights • We developed methods for measuring multiple inequity in health care. • Multiple inequity relates to multiple equity-relevant variables, not just income. • We analysed multiple inequity in physician visits in Brazil using survey data. • Insurance coverage and geography contributed more to multiple inequity than income.

Abstract The Brazilian Unified Health System was created in the late 1980s to ensure free universal access to health care and was funded by taxes and social contributions. The persistent inequity in access to health services in favour of richer individuals in Brazil has been observed in the literature. However, to the best of our knowledge, no measurement of inequality in medicine use or private health insurance (PHI) among children has been performed with longitudinal data. This paper uses inequality indices and their decompositions to analyse the income-related inequalities/inequities in children's health care in the city of Pelotas, Brazil, using longitudinal data following children from 12 to 72 months of age. Our sample with data in all waves has between 1877 and 2638 children (varying according to outcome). We seek to answer three questions: i) How does the inequality/inequity in health care evolve as children grow up? ii) What are the main factors associated with inequality in children's health care? iii) How much of the change in inequality/inequity is explained by mobility in children's health care and income mobility? We found that inequities in health care have their beginnings in early childhood but that there was a reduction in inequity at 72 months of age. Ownership of children's PHI was associated with greater pro-rich inequity in health care. The reduction in inequality/inequity was linked to mobility in the sense that initially poorer children had greater gains in health care (a greater increase in PHI ownership and a lower reduction in medicine use). Despite this improvement among the poorest, apparently, the Brazilian public health service seems to fail to ensure equity in health care use among children, with possible long-term consequences on inequalities in health. Highlights • The inequities in health care have their beginnings even in early childhood. • Income and mother's education have a strong contribution in the inequalities. • Private health insurance has strong contribution in inequalities of medicine use. • There was reduction in inequity for children's health care in Pelotas/Brazil. • This improvement for poorest children occurred when they reached 72 months.

The paper asks why high levels of expressed satisfaction are recorded in settings where health care provision is manifestly inadequate. Qualitative interviews with 30 women aged 25–60 years from a rural district health system of Northeast Brazil were used to explore the applicability of three explanatory models of influences on the construction and expression of satisfaction: expectations; contextual dynamics; mediating filters. The first two of these models argue that a lack of information and a reluctance to be negative respectively lead to high expressed satisfaction that is artificial. The concept of mediating filters proposes that respondents construct an evaluation that takes account of wider issues, such that high levels of expressed satisfaction are, in this sense, real. All three models contribute towards answering the paper's question. However, our data suggest that it is an informed, but low, expectation of health care provision that leads to alternative strategies, including resort to patron–client networks, and success in gaining good health care that is important. Mediating filters identified in this study were culpability and the reference time-frame. We raise questions for practice and offer a combined explanatory model. [Copyright &y& Elsevier]

Since the 1990s, researchers have noted declining trends in crime and violence, particularly homicide, in Western countries. Studies have explored national and sub-national trends using latent trajectory analysis techniques and identified several factors associated with declining and/or increasing trajectories. Social disorganization (SD) has been consistently linked to increases in homicide rates over time, explaining at least some of the spatial and temporal heterogeneity of homicide. Similar studies have not yet been carried out in Latin America's cities. In this paper we use Group Based Trajectory models to study homicide mortality rate [HMR] trajectories in Brazilian municipalities between 1991 and 2010. Then, through binary and multinomial logistic regression we investigated the association between SD in 1991, and the likelihood of an increasing HMR trajectory. We carried out an ecological time series study using all Brazilian municipalities in the period between 1991 and 2010 (n = 4491). Data on homicide deaths were collected from the Mortality Information System of the Ministry of Health and standardized by age to calculate HMR per 100,000 population. Socioeconomic and demographic data for 1991 were used to compose the composite measure of SD. Our results highlight the spatial and temporal heterogeneity of homicide mortality in Brazilian municipalities. While national trends are steadily increasing, disaggregating municipal trajectories shows that this is driven by a small proportion of municipalities in the country. We found that SD is associated with an ascending homicide trajectory. This result generally supports the notion that poor social structural conditions can create ‘space’ for criminal behavior and groups and, consequently, violent death. [ABSTRACT FROM AUTHOR]

Although women's police stations have gained popularity as a measure to address intimate partner violence (IPV), there is little quantitative evaluation of their impacts on the incidence of IPV. This paper estimates the effects of women's police stations in Brazil on female homicides, a measure of the most severe form of IPV. Given that a high fraction of female deaths among women ages 15–49 years can be attributed to aggression by an intimate partner, female homicides appear the best proxy for severe IPV considering the scarcity of data on IPV in Brazil. We assemble a panel of 2074 municipalities from 2004 to 2009 and apply a difference-in-differences approach using location and timing to estimate the effect of establishing a women's police station on the municipal female homicide rate. Although we do not find a strong association on average, women's police stations appear to be highly effective among young women living in metropolitan areas. Establishing a women's police station in a metropolitan municipality is associated with a reduction in the female homicide rate by 1.23 deaths per 100,000 women ages 15–49 years (approximately a 17 percent reduction in the female homicide rate in metropolitan municipalities). The reduction in the homicide rate of women ages 15 to 24 is even higher: 5.57 deaths per 100,000 women. Better economic opportunities and less traditional social norms in metropolitan areas may explain the heterogeneous impacts of women's police stations. [ABSTRACT FROM AUTHOR]

Research on gene-environment interaction was facilitated by breakthroughs in molecular biology in the late 20th century, especially in the study of mental health. There is a reliable interaction between candidate genes for depression and childhood adversity in relation to mental health outcomes. The aim of this paper is to explore the role of culture in this process in an urban community in Brazil. The specific cultural factor examined is cultural consonance, or the degree to which individuals are able to successfully incorporate salient cultural models into their own beliefs and behaviors. It was hypothesized that cultural consonance in family life would mediate the interaction of genotype and childhood adversity. In a study of 402 adult Brazilians from diverse socioeconomic backgrounds, conducted from 2011 to 2014, the interaction of reported childhood adversity and a polymorphism in the 2A serotonin receptor was associated with higher depressive symptoms. Further analysis showed that the gene-environment interaction was mediated by cultural consonance in family life, and that these effects were more pronounced in lower social class neighborhoods. The findings reinforce the role of the serotonergic system in the regulation of stress response and learning and memory, and how these processes in turn interact with environmental events and circumstances. Furthermore, these results suggest that gene-environment interaction models should incorporate a wider range of environmental experience and more complex pathways to better understand how genes and the environment combine to influence mental health outcomes.

In the late 1990s researchers in Pelotas Southern Brazil began documenting what they considered to be unacceptably high rates of licensed psychotropic use among individuals of all ages, including youth. This came as a surprise, since the vast majority of psychiatrists in Pelotas draw on psychoanalytic theory and approach pharmaceutical use, especially for children and adolescents, in a consciously tempered way. Drawing from a longitudinal ethnographic sub-study, part of a larger 1982 birth cohort study, this paper follows the circuitous trajectories of emergent pharma-patterns among “shantytown” youth over a ten-year period, exploring the thickly layered and often moralized contingencies in which psychodynamic psychiatrists' intention to resist excessive pharmaceuticalization both succeed and crumble. I juxtapose these trajectories with the growing salience of an “anti-biologizing” explanatory framework that psychiatrists and researchers are using to pre-empt the kind of diagnostics-driven “biopsychiatrization” so prevalent in North America. My analysis suggests that psychiatrists' use of this framework ironically contributes to their failed attempts to “resist” pharmaceuticalization. [ABSTRACT FROM AUTHOR]

Attention Deficit Hyperactivity Disorder (ADHD) has been medicalized in the United States since the 1960s. Primarily used in North America until the 1990s, ADHD diagnosis and treatment have increasingly been applied internationally. After documenting the expansion of ADHD in a global context, this paper presents five brief international examples examining ADHD usage and expansion: the United Kingdom, Germany, France, Italy and Brazil. We then identify and describe several vehicles that facilitate the migration of the ADHD diagnosis: the transnational pharmaceutical industry; the influence of western psychiatry; moving from ICD to DSM diagnostic criteria; the role of the Internet including the related advent of easily accessible online screening checklists; and advocacy groups. Finally, we discuss what this globalization of a diagnosis reflects about the potential global medicalization of other conditions. [ABSTRACT FROM AUTHOR]

Abstract: There are few comprehensive studies available on barriers encountered from the initial seeking of healthcare through to the resolution of the health problem; in other words, on access in its broad domain. For Colombia and Brazil, countries with different healthcare systems but common stated principles, there have been no such analyses to date. This paper compares factors that influence access in its broad domain in two municipalities of each country, by means of a cross-sectional study based on a survey of a multistage probability sample of people who had had at least one health problem within the last three months (2163 in Colombia and 2155 in Brazil). The results reveal important barriers to healthcare access in both samples, with notable differences between and within countries, once differences in sociodemographic characteristics and health needs are accounted for. In the Colombian study areas, the greatest barriers were encountered in initial access to healthcare and in resolving the problem, and similarly when entering the health service in the Brazilian study areas. Differences can also be detected in the use of services: in Colombia greater geographical and economic barriers and the need for authorization from insurers are more relevant, whereas in Brazil, it is the limited availability of health centres, doctors and drugs that leads to longer waiting times. There are also differences according to enrolment status and insurance scheme in Colombia, and between areas in Brazil. The barriers appear to be related to the Colombian system's segmented, non-universal nature, and to the involvement of insurance companies, and to chronic underfunding of the public system in Brazil. Further research is required, but the results obtained reveal critical points to be tackled by health policies in both countries. [Copyright &y& Elsevier]

Ecosyndemics refer to disease interactions that result from environmental changes commonly caused by humans. In this paper, we push scholarship on ecosyndemics into new territory by using the ecosyndemic framework to compare two case studies—the Southern Interoceanic highway in Peru and the Belo Monte hydroelectric dam in Brazil—to assess the likelihood of socio-environmental factors interacting and leading to ill health in a syndemic fashion. Assessing these two case studies using an ecosyndemic perspective, we find that the construction of dams and highways in tropical forests create the conditions for increases in vector-borne illnesses, surges in sex work and sexually-transmitted infections, and increased psychological stress resulting from violence, delinquency, and the erosion of social cohesion. We suggest that these processes could interact synergistically to increase an individual's immune burden and a population's overall morbidity. However, we find differences in the impacts of the Interoceanic highway and the Belo Monte dam on food, water, and cultural systems, and observed that community and corporate-level actions may bolster health in the face of rapid socio-ecological change. Looking at the case studies together, a complex picture of vulnerability and resilience, risk and opportunity, complicates straight-forward predictions of ecosyndemic interactions resulting from these development projects but highlights the role that the ecosyndemic concept can play in informing health impact assessments and future research. We conclude by proposing a conceptual model of the potential interactions between psychological stress, vector-borne illnesses, and sexaully-transmitted infections and suggest that future investigations of synergistic interactions among these factors draw from the biological, social, and ecological sciences. • Ecosyndemics are disease interactions ignited by eco-social changes. • We compared two Amazonian mega-development projects using an ecosyndemic framing. • Projects were Belo Monte dam in Brazil and the Interoceanic highway in Peru. • Potential synergism among stress, vector-borne and sexually-transmitted infections. • Researchers should use interdisciplinary methods to further examine dynamics.

Abstract: Over the last decade, the Brazilian alcohol industry – which for years has ignored alcohol problems – inaugurated responsible drinking programs (RDPs). This paper reports findings from an exploratory study that investigated the RDP-related activities of six leading alcohol companies in Brazil (three national, three transnational) focusing on program goals and components, target populations and evaluation methods. Interviews were conducted from October 2007 to February 2008 with nine key-informants, and 71 corporate documents were collected along with additional web information about the programs. Content analysis of interviews and institutional documents was used to identify the companies’ RDP activities. Three types of RDPs were found that focused respectively on institutional action, drinking and driving, and underage drinking. All three transnational firms were involved in RDPs, whereas national firms demonstrated limited involvement. The majority of RDPs were implemented using television. No targeted research appears to have been undertaken by the companies to assess the efficacy of the strategies in terms of changes in drinking behavior. The evidence for both national and transnational firms means that is difficult to confirm that the responsible drinking programs produced so far in Brazil have been undertaken to systematically reduce alcohol problems, or mainly as part of a public relations strategy to reduce criticism and potentially forestall government regulations ().

Abstract: Community Health Workers (CHWs) play a pivotal role in primary care, serving as liaisons between community members and medical providers. However, the growing reliance of health care systems worldwide on CHWs has outpaced research explaining their praxis – how they combine indigenous and technical knowledge, overcome challenges and impact patient outcomes. This paper thus articulates the CHW Praxis and Patient Health Behavior Framework. Such a framework is needed to advance research on CHW impact on patient outcomes and to advance CHW training. The project that originated this framework followed Community-Based Participatory Research principles. A team of U.S.-Brazil research partners, including CHWs, worked together from conceptualization of the study to dissemination of its findings. The framework is built on an integrated conceptual foundation including learning/teaching and individual behavior theories. The empirical base of the framework comprises in-depth interviews with 30 CHWs in Brazil’s Unified Health System, Mesquita, Rio de Janeiro. Data collection for the project which originated this report occurred in 2008–10. Semi-structured questions examined how CHWs used their knowledge/skills; addressed personal and environmental challenges; and how they promoted patient health behaviors. This study advances an explanation of how CHWs use self-identified strategies – i.e., empathic communication and perseverance – to help patients engage in health behaviors. Grounded in our proposed framework, survey measures can be developed and used in predictive models testing the effects of CHW praxis on health behaviors. Training for CHWs can explicitly integrate indigenous and technical knowledge in order for CHWs to overcome contextual challenges and enhance service delivery. [Copyright &y& Elsevier]

Abstract: Explanations for the association between teen-childbearing and subsequent mental morbidity vary considerably, from those based on neurological theories of development to those investigating underlying social and economic determinants. Based on longitudinal epidemiological and ethnographic sub-studies of the 1982 Pelotas birth cohort study, this paper explores the hypothesis that teen childbearing and subsequent mental morbidity have become associated through the interplay of culture, society, and biology in situations where teen pregnancy has become a stigmatised object of scientific and public health attention. Results show that the effect of teen childbearing on subsequent mental morbidity remained significant in the multivariate analysis. Ethnographic analysis, together with epidemiological effect modification analyses, suggest that this association is partially accounted for by the fact that it is more pronounced amongst a specific subgroup of women of low socio-economic status who, being more politicised about societal injustice, were also more critically engaged with – and thus troubled by – the inequitable institutionalisation of life-cycle transitions. With time, these women became highly critical of the institutionalised identification of early childbearing as a key violation of life-cycle norms and the differential class-based application of scientific knowledge on its causes and consequences. Public health campaigns should consider how the age-based institutionalisation of developmental norms has enabled the stigmatisation of those identified as transgressors. [Copyright &y& Elsevier]

Abstract: Funds to promote access to water and sanitation in developing countries are scarce and most of the investments come from the national governments and households sources, not international resources. In many of these countries, mainly in middle income countries, households are paying direct taxes to access these services, and understanding what determines their choice and motivation is fundamental to promote access to them. It has been argued that is not enough to supply a wide range of alternatives unless the individuals can recognise their benefits and sustainability. The objective of this paper is to understand the choice of sanitation technology by residents in the city of Salvador, Brazil. We propose a unique hybrid choice model that incorporates a set of latent attitudinal variables and explains how the demographic factors within a household influence choice. The substantial difference of our hybrid choice model from descriptive frameworks is that it integrates choice and latent variables (such as attitudes and preferences) allowing us to model explicitly the cognitive process that influences sanitation adoption, draw conclusions from cognitive variables associated with individuals’ socio-economic and demographic characteristics, and establishes a causal pathway among these variables. The results show that the attributes of health protection, accessibility, privacy, and house modernisation were what households cared about when opting for flush toilet and sewerage connection, rather than the high cost and consequent household socio-economic status associated with them. The hybrid model is statistically consistent with these findings, and seems to fill the gap between behavioural theory and discrete choice models applied to sanitation. [Copyright &y& Elsevier]

Unintended pregnancies constitute a serious public health concern in Brazil, representing up to 55% of all pregnancies, and are prevalent among women with low income and low educational backgrounds. Lack of assistance to women in their decision-making has hindered the adoption of more effective contraceptive models. Although clinical consultations constitute an important locus to assist women in decision-making and to facilitate access to subsidized methods, our current knowledge of how contraception is discussed and decisions are reached in actual consultations is limited. Just as scarce is our knowledge of how patients respond and resist contraception recommendations and how physicians counter or accommodate patients. Using a corpus of 103 audio-recorded medical visits and conversation analytic (CA) methods, this paper examines recommendation sequences in the under-investigated gynecological consultations in the Brazilian public healthcare system (SUS). The quantitative analysis reveals a strong orientation to physicians as having primary rights to govern the oversight of women's bodies: 94% of the recommendations are delivered as pronouncements (e.g. , "You'll take X″), the most authoritative action type. Patients largely assume an agreeable and passive role (66%), leading to scarce negotiation and minimal involvement in decision-making. However, in a few cases (12%), all involving contraception, patients become overtly agentive, responding with active resistance. A qualitative analysis of that subset shows that despite women's gaining some agency over their sexual bodies, that agency is still limited. Whereas physicians accommodate patient resistance on grounds of biomedically-related side-effects and incorrect assumptions about the women's lives, they overlook patient resistance based on gendered struggles over contraceptive methods in the domestic sphere. By failing to consider women's lack of agency in choosing whether to have sex or to use condoms, doctors show unawareness of significant consequences of the recommended method, which might include domestic dispute and violence and, paradoxically, ultimately misfire, leading to unwanted pregnancy. • Unintended pregnancies constitute a serious public health concern in Brazil. • Lack of assistance with decision-making hinders best-suited contraception use. • Medical consultations are valuable interactional spaces to discuss contraception. • Women gain by resisting ill-suited recommendations to their own life circumstances. • Contraception decision and access demand partnership between doctors and patients.

Little evidence is available about the utility of web-based health education for students in low resource settings. This paper reports results from an evaluation of the TeenWeb project, a multi-year, web-based health education intervention implemented in two urban settings: Nairobi, Kenya (N =1178 school students) and Rio de Janeiro, Brazil (N =714 school students). A quasi-experimental, school-based pre-test/post-test design was implemented at each study site to determine if easy access to web-based reproductive health information, combined with intellectual “priming” about reproductive health topics, would result in improved knowledge and attitudes about topics such as condom use, access to HIV testing, emergency contraception and abortion laws. Students in web-access schools completed one web-based module approximately every 6–8 weeks, and in return, had access to the Internet for at least 30min after completing each module. Although students were encouraged to access project-supplied web-based health information, freedom of web navigation was an incentive, so they could choose to access other Internet content instead. Most measures showed statistically significant differences between students in “web” and “comparison” conditions at post-test, but only about half of the differences were in the hypothesized direction. Results of an embedded experiment employing more directed feedback tripled the likelihood of correctly reporting the duration of emergency contraception effectiveness. Review of URL logs suggests that the modest results were due to inadequate exposure to educational materials. Future intervention should focus on teen's purposeful searching for health information when they are in personal circumstances of unmet health needs. [Copyright &y& Elsevier]

Abstract: Cultural consonance refers to the degree to which individuals, in their own beliefs and behaviors, approximate the prototypes for belief and behavior encoded in shared cultural models. In previous cross-sectional studies, lower cultural consonance in several cultural domains was associated with worse health outcomes, including greater psychological distress. The current paper extends these findings in three ways. First, the effect of cultural consonance on depressive symptoms is tested in a prospective study. Second, it is hypothesized that the effect of cultural consonance in a specific cultural domain will depend on the degree of cultural consensus within that domain: the higher the cultural consensus, the greater the effect of change in cultural consonance in that domain on depressive symptoms. Third, it is hypothesized that cultural consonance will have an inverse effect on depressive symptoms independent of the occurrence of stressful life events (a well-known risk factor for depression). We tested these hypotheses in a study conducted in urban Brazil, and found that change in cultural consonance (assessed as a general construct) was associated with depressive symptoms at a 2-year follow-up. Furthermore, cultural consonance in the domains in which there was highest cultural consensus—the domains of family life and lifestyle—was more strongly associated with depressive symptoms at follow-up than cultural consonance in domains with lower cultural consensus. Finally, all of these effects were independent of stressful life events. These results lend further support to the importance of cultural consonance in relation to human health.

Abstract: Recent years have seen a burgeoning of intergenerational programmes aiming to improve the well being of participants. However, very few programmes have been formally evaluated. In this paper we report results from a randomised controlled trial of a school-based intergenerational intervention undertaken in Brazil. Randomly selected samples of 253 adolescents and 266 elders aged 60 and over resident in the school''s catchment area were administered a questionnaire including questions on cognitive components of social capital, family relationships, and self-rated health. Participants were then randomly allocated to control and intervention groups. The intervention comprised participation in a 4 month programme of intergenerational activities in which the elders shared their memories with the students. At the end of the intervention the questionnaire was re-administered to the samples. High proportions (85–95%) of both samples completed the questionnaires but compliance with the intervention was low in the elderly group. In the analysis of results from the elderly sample, we therefore compared the control group with the group assigned to the intervention (intention to treat analysis). Results showed that adolescents in the intervention group were nearly three times more likely to rate their health as good than those in the control group, but also more likely to judge that most people were selfish. In the elderly sample, those from the intervention group were over twice as likely as those from the control group to report positively on the helpfulness of neighbours; judge most people to be honest or consider their family relationships as good. There were no significant differences between groups on other outcome measures. These results suggest that structured intergenerational activities may have positive effects on some aspects of social capital for both adolescents and elderly people, although further research is needed to elucidate the processes involved and the extent to which the findings are context specific. This study is the first to use a controlled trial design to evaluate this type of intervention and is valuable in showing that this design can be used in interventions of this kind, and also the difficulties involved.

Abstract: In a country where quality HIV/AIDS prevention and care has been foremost on the national agenda, Brazil''s extensive and diverse borders are one of the last unstudied potential hotbeds of HIV vulnerability. We carried out a rapid assessment of HIV-related services and the social context of HIV/AIDS at the Brazilian borders including current governmental and community response. The assessment was implemented in six frontier municipalities using the WHO''s strategic approach methodology, which combines existing epidemiologic data with field-based qualitative data collection techniques, including observation of service delivery points and in-depth interviews and focus groups with local leaders, providers, and community members, in order to recommend context-specific HIV prevention strategies. This paper focuses on the qualitative findings regarding the role of the social context in shaping HIV vulnerability at the Brazilian borders. We documented a profound lack of governmental structure and response to HIV/AIDS at the borders as well as a notable absence of social cohesion and mobilization among the diverse population groups and communities situated at the borders with regard to HIV/AIDS. The weak governmental and community response is situated within a larger socio-political context of economic inequity and social division, which must be addressed if an effective response to HIV can be developed at Brazil''s international borders. Possibilities for encouraging a collective response among the diverse border populations are explored. [Copyright &y& Elsevier]

This paper explores the reproductive preferences and outcomes of HIV-positive women in two cities in Brazil. We used three types of data, all drawn from women who delivered in public sector hospitals: (1) clinical records of 427 HIV-positive women; (2) pre- and postpartum in-depth interviews with 60 HI V-positive women; and (3) a prospective survey carried out among 363 women drawn from the general population. The HI V-positive samples were collected on women who had prenatal care between July 1999 and June 2000, and the general population survey was conducted with women who started prenatal care between April 1998 and June 1999. Among the women in the clinic sample, we found dramatic differences in the proportion sterilized postpartum: 51 % in São Paulo vs. 4% in Porto Alegre, compared to 3.4% and 1.1 %, respectively, of women in the general population. Our qualitative data suggest that HIV-positive women in this study had strong preferences to have no more future children and that female sterilization was the preferred way to achieve this end. Therefore, we conclude that the large difference in rates is mainly due to HI V-positive women's differential access to sterilization in the two settings. In-depth interviews revealed that women in São Paulo were often encouraged by clinic staff to be sterilized postpartum. In contrast, HIV-positive women in Porto Alegre clinics were not offered sterilization as an option and those who requested it were repeatedly put off. The striking difference found in the frequency with which doctors provide postpartum sterilization to seropositive women in our study sites deserves attention and discussion in the respective medical communities. At the higher level of national policy on reproductive rights, there may be grounds for reopening discussion about the norms regarding postpartum procedures, and for devoting far more resources to expanding contraceptive options.

Abstract: In this paper, we examine trends and differentials in diarrhea prevalence and treatment in Brazil between 1986 and 1996. Our results indicate that there was a very modest decline in diarrhea prevalence in Brazil over this ten-year period. However, treatment with oral rehydration therapy (ORT) increased greatly. Although deaths due to diarrhea were reduced, high disease rates continue to place a large number of children at risk of adverse nutritional and developmental outcomes. There were dramatic differences in diarrhea prevalence across socioeconomic groups and regions that persisted over time, although the large regional differential in ORT treatment that was present in 1986 had disappeared by 1996. The persistence of high rates of diarrhea indicates that reducing the prevalence of the disease continues to be a major public health priority. The large differential in the prevalence of diarrhea across socioeconomic groups and regions means that interventions to prevent the disease should be targeted towards the most disadvantaged segments in Brazil, which also face the highest child mortality rates.

Much has been written about the socioeconomic distribution of nutritional status, both in more economically developed, and in developing nations. In general, persons of lower socioeconomic status suffer adverse consequences of poor nutritional status, although these consequences can vary depending on the level of development, i.e. in more developed countries the problem tends to be one of over-nutrition and obesity, while in developing countries the problem tends to be one of under-nutrition and nutritional deficiencies. In this paper, we explore the socioeconomic distribution of dietary intake in a Brazilian city, in an area that in some ways is neither prototypically developed or underdeveloped. The analysis presented here was stimulated by the surprising observation of no socioeconomic differences in total caloric intake in the context of extreme differences in income distribution. Further examination showed that socioeconomic differences in total caloric intake appeared after controlling for alcohol intake. A complete analysis of the data suggests that lower income leads to lower cultural consonance, which in turn leads to higher depression, higher alcohol intake, and higher total caloric intake. In this model, alcohol ingestion can be seen as both a psychological and nutritional adaptive strategy to economic, social and cultural marginality in a highly stratified society.

In this paper, we propose an approach to investigate the hypothesis that the residential concentration of poverty affects health status more deeply than when poverty is randomly scattered in a given geographical area. To characterize the geographic pattern of poverty in the city of Rio de Janeiro, Brazil, an index that measures the heterogeneity of poverty concentration among sub-areas was proposed. We used census data and defined poverty by means of the household head monthly income. The 153 neighborhoods that compose the city were used as the geographic units, and the census tracts as the sub-areas. The proposed index measures differences of poverty concentration across census tracts within a neighborhood. The effects of geographic poverty clustering on infant mortality related variables (early neonatal mortality rate; post-neonatal mortality rate; proportion of adolescent mothers; and fertility rate among adolescents) were estimated by partial correlation coefficients, controlling for the neighborhood poverty rate. Our study revealed that intra-city variations of the post-neonatal mortality rate are associated with geographic patterns of poverty, and that pregnancy in adolescence is strongly and contextually correlated with intra-neighborhood poverty clustering, even after adjustment for the poverty rate. The evidence of relevant health differences associated with the spatial concentration of poverty supports the hypothesis that properties of the environment of residence contextually influence health. Our findings suggest that prevention of some infant mortality related problems has to be focused directly on features of communities, considering their physical, cultural and psychosocial characteristics, being of particular concern the health of communities segregated from the society at large by extreme poverty.

The rapid spread of COVID-19 across the world has raised concerns about the responsiveness of cities and healthcare systems during pandemics. Recent studies try to model how the number of COVID-19 infections will likely grow and impact the demand for hospitalization services at national and regional levels. However, less attention has been paid to the geographic access to COVID-19 healthcare services and to hospitals' response capacity at the local level, particularly in urban areas in the Global South. This paper shows how transport accessibility analysis can provide actionable information to help improve healthcare coverage and responsiveness. It analyzes accessibility to COVID-19 healthcare at high spatial resolution in the 20 largest cities of Brazil. Using network-distance metrics, we estimate the vulnerable population living in areas with poor access to healthcare facilities that could either screen or hospitalize COVID-19 patients. We then use a new balanced floating catchment area (BFCA) indicator to estimate spatial, income, and racial inequalities in access to hospitals with intensive care unit (ICU) beds and mechanical ventilators while taking into account congestion effects. Based on this analysis, we identify substantial social and spatial inequalities in access to health services during the pandemic. The availability of ICU equipment varies considerably between cities, and it is substantially lower among black and poor communities. The study maps territorial inequalities in healthcare access and reflects on different policy lessons that can be learned for other countries based on the Brazilian case. • Use of a Balanced Floating Catchment Area to calculate accessibility to healthcare. • Estimates access to healthcare in the 20 largest Brazilian cities during COVID-19. • Over 1.6 million people have poor access to healthcare for severe cases of COVID-19. • 41% of vulnerable population have poor access to ICU beds and mechanical ventilators. • Low income and black communities in urban periphery have less healthcare access.

Despite having free access to the public health system, 25% of the Brazilian population have a private insurance plan, which is subsidized by the government by means of an income tax rebate. This paper explores this rebate to tackle the potential endogeneity between private insurance and the demand for health services, using the fiscal incentive as a source of quasi-experimental variation in insurance prices. We estimate the average effect of private insurance for the marginal individuals at the kink points by means of a nonseparable nonparametric regression model. Our data allow us to disentangle moral hazard from adverse selection effects and the results indicate that private insurance has a positive impact on the use of preventive services, health outcomes, physical exercises, and smoke quiting, and does not impact the use of nonpreventive health services, such as inpatient services and surgeries. • We estimate the effect of health insurance on health service utilization in Brazil. • We use a regression kink design exploring the piecewise income tax rebate rules. • The probability of health insurance increases around the tax rate cutoffs. • Supplemental coverage has a positive impact over preventive care utilization. • We find no effects on non-preventive care services.

This article explores the mobilization of power by health workers during policy implementation, showing how in a context of discretion and resource scarcity they can reproduce inequalities in access to health services. The argument innovates theoretically by supplementing the 'street-level bureaucracy' literature, which emphasizes frontline worker discretion, with a conceptualization of power as domination encompassing the shaping of behavior, the constitution of subjects and the reproduction of inequality. Empirically, the article focuses on Brazilian community health workers (agentes comunitários de saúde , CHWs). CHWs are a neglected but highly important segment of the health workforce that traditionally functions as a link between the health system and disadvantaged groups. The article examines how Brazilian CHWs act as street-level bureaucrats mobilizing power in their interactions with users. They operate within a severely under-resourced public health system, the Sistema Único de Saúde , which places constraints upon their action and forces them to make allocation decisions with little training and support. The article highlights the ways in which inequalities in access to health services are reproduced (inadvertently or not) through the practices, discursive styles and classifications of CHWs. Methodologically, the paper is based on ethnography with 24 CHWs and interviews with 77 other CHWs in Brazil. • Develops a novel framework for analysing health worker discretion and power. • Supplements the street-level bureaucracy approach with the concept of domination. • Explores the mobilization of power by Brazilian community health workers. • Shows how policy implementation can reproduce inequality in access to healthcare.
