Criminal Justice in Transition: The Northern Ireland Context

This book represents a critical examination of key aspects of crime and criminal justice in Northern Ireland which will have resonance elsewhere. It considers the core aspects of criminal justice policymaking in Northern Ireland which are central to the process of post-conflict transition, including reform of policing, judicial decision-making and correctional services such as probation and prisons. It examines contemporary trends in criminal justice in Northern Ireland as related to various dimensions of crime relating to female offenders, young offenders, sexual and violent offenders, race and criminal justice, community safety and restorative justice. The book also considers the extent to which crime and criminal justice issues in Northern Ireland are being affected by the broader processes of ‘policy transfer’, globalisation and transnationalism and the extent to which criminal justice in Northern Ireland is divergent from the other jurisdictions in the United Kingdom. Written by leading international authorities in the field, the book offers a snapshot of the cutting edge of critical thinking in criminal justice practice and transitional justice contexts.

Reliability of reports of childhood trauma in bipolar disorder: A test–retest study over 18 months

This study aimed to explore the reliability of self-reported trauma histories in a population with a diagnosis of Bipolar Disorder using the Childhood Trauma Questionnaire. Previous studies in other populations suggest high reliability of trauma histories over time and it was postulated that a similar high reliability would be demonstrated in this population. Thirty-nine patients with a confirmed diagnosis (DSM-IV criteria) were followed-up and re-administered the Childhood Trauma Questionnaire after 18 months. Cohen's kappa scores and intraclass correlations suggest reasonable test-retest reliability over the 18-month time period of the study for all types of childhood abuse, namely emotional, physical, sexual, and physical abuse and emotional neglect. Intraclass correlations ranged from r = .50 to (sexual abuse) to r = .96 (physical abuse). Cohen's kappas ranged from .44 (sexual abuse) to .76 (physical abuse). Retrospective reports of childhood trauma can be seen as reliable and are in keeping with results found with other mental health populations.

The role of knowledge in the contraceptive behaviour of sexually active young people in state care

Aim: To analyse the role of sex-focused knowledge in the contraceptive behaviour of sexually active young people in state care.

Methods: The sample consisted of 19 care leavers (young people previously in state care) aged 18-22 years, 16 females and 3 males. In-depth interviewing was the method of data collection, and a qualitative strategy resembling modified analytical induction was used to analyse data.

Findings: Findings indicated that a lack of information was not the sole, or even the primary reason for engaging in unsafe sexual practices. Other factors such as ambivalence to becoming pregnant also featured in participants’ accounts. Several participants conveyed a relatively weak sense of agency about consistently using contraception. A small number of participants expressed a strong determination to avoid pregnancy, and these appeared to have a level of anxiety about becoming pregnant that motivated them to engage with knowledge about contraception and its use.

Conclusion: Lack of sex-focused information is just one aspect of a myriad of complex factors, including socioeconomic disadvantage and/or emotional deprivation, that influences contraceptive behaviour.

Seven key actions to eradicate rheumatic heart disease in Africa: the Addis Ababa communiqué

Acute rheumatic fever (ARF) and rheumatic heart disease (RHD) remain major causes of heart failure, stroke and death among African women and children, despite being preventable and imminently treatable. From 21 to 22 February 2015, the Social Cluster of the Africa Union Commission (AUC) hosted a consultation with RHD experts convened by the Pan-African Society of Cardiology (PASCAR) in Addis Ababa, Ethiopia, to develop a 'roadmap' of key actions that need to be taken by governments to eliminate ARF and eradicate RHD in Africa. Seven priority areas for action were adopted: (1) create prospective disease registers at sentinel sites in affected countries to measure disease burden and track progress towards the reduction of mortality by 25% by the year 2025, (2) ensure an adequate supply of high-quality benzathine penicillin for the primary and secondary prevention of ARF/RHD, (3) improve access to reproductive health services for women with RHD and other non-communicable diseases (NCD), (4) decentralise technical expertise and technology for diagnosing and managing ARF and RHD (including ultrasound of the heart), (5) establish national and regional centres of excellence for essential cardiac surgery for the treatment of affected patients and training of cardiovascular practitioners of the future, (6) initiate national multi-sectoral RHD programmes within NCD control programmes of affected countries, and (7) foster international partnerships with multinational organisations for resource mobilisation, monitoring and evaluation of the programme to end RHD in Africa. This Addis Ababa communiqué has since been endorsed by African Union heads of state, and plans are underway to implement the roadmap in order to end ARF and RHD in Africa in our lifetime.

Linking Family Engagement with a Rights Perspective: Macro Factors Influencing Practice

While child welfare practitioners in many countries are struggling to develop methods of effective family engagement, they operate within different national and cultural contexts which influence, both positively and negatively, the ability to engage with families. Increasingly, international comparisons are necessary to further understanding of the development of social work practice. This is particularly necessary because most countries utilize international frameworks (such as the United National Convention on the Rights of the Child) to provide guidance in the development of policies, programs, and interventions. Each country (and locality) struggles to advance practice to be more effective and humane. Our paper offers a comparative analysis focused on family-oriented and rights-based frameworks of different countries. Based on a review of current national policies and a review of the literature regarding family based practices, we examine similarities and differences among four countries: the United Kingdom, Sweden, the United States, and South Korea. These countries were selected because they have some similarities (advanced industrialized democracies, professional social work, formal child protection systems) but have some differences in their social welfare systems (policies, specific practices, socio-cultural context). These differences can be utilized to advance understanding regarding the promise and potential for family engagement strategies. We then discuss the utility of this comparison for theory-building in the arena of child care practice and conclude by identifying the challenges and limitations of this work.

Avaliação do efeito de metais pesados na fertilidade do ratinho

A infertilidade é um problema actual que afecta cerca de 8 a 12% dos casais em idade fértil, sendo 50% dos casos atribuídos ao factor masculino. A exposição ocupacional e/ou ambiental a metais pesados representa uma das suas principais causas. O chumbo, o cádmio e o crómio são metais com elevada utilização industrial e muito persistentes no ambiente, sendo motivo de grande preocupação devido aos seus efeitos na saúde reprodutiva dos trabalhadores e da população em geral. Neste trabalho estudaram-se os efeitos do cloreto de chumbo (PbCl2), cloreto de cádmio (CdCl2) e cromato de potássio (K2CrO4) na fertilidade, usando como modelo ratinhos machos ICR-CD1. Os ratinhos foram injectados subcutaneamente com 74 e 100 mg de PbCl2/kg pc ou com 5 e 10 mg de K2CrO4/kg pc, respectivamente, durante 4 dias consecutivos ou com 1, 2 e 3 mg de CdCl2/kg pc numa única injecção. Nos ensaios com PbCl2 e K2CrO4 os animais foram sacrificados 5 e 35 dias após o início da exposição, enquanto que nos ensaios com CdCl2 os animais foram sacrificados após 24 horas e 35 dias. O cloreto de chumbo não alterou a histologia do testículo nem do epidídimo, mas induziu um aumento da percentagem de células em fase S no testículo. O cloreto de chumbo alterou também alguns parâmetros dos espermatozóides, tais como a motilidade, morfologia e integridade do acrossoma. Contudo, não foram observados efeitos na integridade do DNA ou na estrutura da cromatina. O cloreto de cádmio induziu lesões severas e não reversíveis nos testículos que, após 35 dias, reverteram em necrose testicular. O cloreto de cádmio alterou ainda as subpopulações de células testiculares após 24 horas e induziu IMS no testículo após 35 dias. Em consequência das lesões no testículo, a densidade espermática foi severamente afectada após 35 dias. A exposição ao cloreto de cádmio afectou também a morfologia, a motilidade e a integridade acrossómica nos espermatozóides. O cloreto de cádmio induziu ainda fragmentação do DNA nestas células após 35 dias. O cromato de potássio alterou a morfologia dos espermatozóides e a integridade do acrossoma, sobretudo nos animais sacrificados após 35 dias. Verificou-se ainda uma redução da motilidade dos espermatozóides. Não foram detectados efeitos genotóxicos nos espermatozóides, devido à acção do K2CrO4 nas doses testadas. Dos parâmetros avaliados neste trabalho, destacam-se duas novas abordagens, nomeadamente o programa informático Snakes e a análise do conteúdo em DNA de células de testículo, a partir de material incluído em parafina. O Snakes permitiu fazer medições rigorosas do diâmetro dos tubos seminíferos, enquanto que a fixação de amostras de testículo de ratinhos em formol tamponado e inclusão em parafina resultou numa boa preservação do DNA, possibilitando assim a quantificação das subpopulações de células testiculares por citometria de fluxo. Os resultados obtidos para os diferentes parâmetros testados indicam que a motilidade dos espermatozóides e a integridade do acrossoma sejam parâmetros sensíveis à toxicidade de metais. O acrossoma aparenta ser um dos principais alvos da toxicidade dos metais e cuja reacção acrossómica prematura pode reduzir a capacidade do espermatozóide para fertilizar o oócito. Assim, este trabalho representa uma contribuição para uma melhor compreensão dos efeitos do chumbo, cádmio e crómio na fertilidade masculina.

The role of the hypothalamic kisspeptin/GPR54 system in the control of GnRH neurons

Summary : The hypothalamus represents less than 1 % of the total volume of the brain tissue, yet it plays a crucial role in endocrine regulations. Puberty is defined as a process leading to physical, sexual and psychosocial maturation. The hypothalamus is central to this process, via the activation of GnRH neurons. Pulsatile GnRH secretion, minimal during childhood, increases with the onset of puberty. The primary function of GnRH is to regulate the growth, development and function of testes in boys and ovaries in girls, by stimulating the pituitary gland secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Several factors contribute to the timing of puberty, including sex and ethnicity, genetics, dietary intake and energy expenditure. Kisspeptins constitute a family of small peptides arising from the proteolytic cleavage of metastin, a peptide with 54 amino acids initially purified from human placenta. These kisspeptins were the subject of much attention following their discovery because of their antimetastatic properties, but it was more recently that their determining role in the reproductive function was demonstrated. It was shown that kisspeptins are ligands of a receptor, GPR54, whose natural inactivating mutation in humans, or knockout in the mouse, lead to infertility. GnRH neurons play a pivotal role in the central regulation of fertility. Kisspeptin greatly increases GnRH release and GnRH neuron firing activity, but the neurobiological mechanisms for these actions are unknown. Gprotein-coupled receptor 54, the receptor for kisspeptin, is expressed by GnRH neurons as well as other hypothalamic neurons, suggesting that both direct and indirect effects are possible. In the first part of my thesis, we investigated a possible connection between the acceleration of sexual development induced by leptin and hypothalamic metastin neurons. However, the data generated by our preliminary experiments confirmed that the commercially available antibodies are non-specific. This finding constituted a major drawback for our studies, which relied heavily upon the neuroanatomical study of the hypothalamic metastinergic pathways to elucidate their sensitivity to exogenous leptin. Therefore, we decided to postpone any further in vivo experiment until a better antibody becomes available, and focused on in vitro studies to better understand the mechanisms of action of kisspeptins in the modulation of the activity of GnRH neurons. We used two GnRH-expressing neuronal cell lines to investigate the cellular and molecular mechanisms of action of metastin in GnRH neurons. We demonstrated that kisspeptin induces an early activation of the MAP kinase intracellular signaling pathway in both cell lines, whereas the SAP/JNK or the Akt pathways were unaffected. Moreover, we found an increase in GnRH mRNA levels after 6h of metastin stimulation. Thus, we can conclude that kisspeptin regulates GnRH neurons both at the secretion and the gene expression levels. The MAPK pathway is the major pathway activated by metastin in GnRH expressing neurons. Taken together, these data provide the first mechanism of action of kisspeptin on GnRH neurons. Résumé : L'hypothalamus est une zone située au centre du cerveau, dont il représente moins de 1 du volume total. La puberté est la période de transition entre l'enfance et l'age adulte, qui s'accompagne de transformations somatiques, psychologiques, métaboliques et hormonales conduisant à la possibilité de procréer. La fonction principale de la GnRH est la régulation de la croissance, du développement et de la fonction des testicules chez les hommes, et des ovaires chez les femmes en stimulant la sécrétion de l'hormone lutéinisante (LH) et de l'hormone folliculostimulante (FSH) par la glande hypophysaire. Plusieurs facteurs contribuent au déclanchement de la puberté, y compris le sexe et l'appartenance ethnique, la génétique, l'apport alimentaire et la dépense énergétique. Les Kisspeptines constituent une famille de peptides résultant de la dissociation proteolytique de la métastine, un peptide de 54 acides aminés initialement purifié à partir de placenta humain. Ces kisspeptines ont fait l'objet de beaucoup d'attention à la suite de leur découverte en raison de leurs propriétés anti-metastatiques, et c'est plus récemment que leur rôle déterminant dans la fonction reproductive a été démontré. Les kisspeptines sont des ligands du récepteur GPR54, dont la mutation inactivatrice chez l'homme, ou le knockout chez la souris, conduisent à l'infertilité par hypogonadisme hypogonadotrope. Les neurones à GnRH jouent un rôle central dans le règlement des fonctions reproductrices et la kisspeptine stimule l'activité des neurones à GnRH et la libération de GnRH par ces neurones. Toutefois, les mécanismes neurobiologiques de ces actions ne sont pas connus. Dans la première partie de ma thèse, nous avons étudié le lien potentiel entre l'accélération du développement sexuel induite par la leptine et les neurones hypothalamiques à metastine. Les données générées dans cette première série d'expériences ont malheureusement confirmé que les anticorps anti-metastine disponibles dans le commerce sont aspécifiques. Ceci a constitué un inconvénient majeur pour nos études, qui devaient fortement s'appuyer sur l' étude neuroanatomique des neurones hypothalamiques à metastine pour évaluer leur sensibilité à la leptine exogène. Nous avons donc décidé de focaliser nos travaux sur une étude in vitro des mécanismes d'action de la kisspeptine pour moduler l'activité des neurones à GnRH. Nous avons utilisé deux lignées de cellules neuronales exprimant la GnRH pour étudier les mécanismes d'action cellulaires et moléculaires de la metastine dans des neurones. Nous avons ainsi pu démontrer que la kisspeptine induit une activation précoce de la voie f de signalisation de la MAP kinase dans les deux lignées cellulaires, alors que nous n'avons observé aucune activation de la voie de signalisation de la P13 Kinase et de la SAP/JNK. Nous avons en outre démontré une augmentation de l'expression de la GnRH par la stimulation avec la Kisspeptine. L'ensemble de ces données contribue à élucider le mécanisme d'action avec lequel la kisspeptine agit dans les neurones à GnRH, en démontrant un effet sur l'expression génique de la GnRH. Nous pouvons également conclure que la voie de la MAPK est la voie principale activée par la metastine dans les neurones exprimant la GnRH.

L’expérience de la maternité des Ouagalaises : d’une génération à l’autre

Ce mémoire porte sur l’expérience de la maternité des Ouagalaises et son évolution. Il s’intéresse au déroulement de la première grossesse, de l’accouchement et de l’entrée en maternité de deux générations de femmes. Privilégiant une approche holistico-inductive en méthodologie qualitative, notre recherche s’est appuyée sur 31 entretiens semi-directifs avec des Ouagalaises, sur 15 d’heures d’observation participante à la maternité ainsi que sur 10 d’entretiens semi-directifs avec des sages-femmes. Les résultats de l’analyse montrent que le savoir de la maternité se transmet toujours de génération en génération, et qu’il demeure encore fortement encadré par les aînées. Toutefois, les transformations en cours dans le système de santé et dans la société burkinabè ne sont pas sans incidence dans la capitale. Les jeunes femmes étant plus renseignées en matière de santé reproductive, elles ont davantage reconnu les signes de la grossesse et le début des douleurs de l’accouchement. Les accompagnantes n’ayant plus accès à la salle d’accouchement et le pouvoir des sages-femmes s’agrandissant, l’expérience de l’accouchement se modifie. Bien que les vieilles femmes n’aient plus le même contrôle sur les parturientes durant l’accouchement, leur influence est toutefois toujours très importante pendant la période post-partum. Les femmes de la jeune génération n’étant généralement pas encore mariées ou installées dans leur propre maison au moment de la grossesse, la promiscuité avec leur belle-mère à l’issue de l’accouchement augmente et le pouvoir de cette dernière est plus important qu’il ne l’était à l’époque de la génération précédente.

La pertinence et les enjeux éthiques d'interventions de santé publique envers l'infertilité et l'âge maternel avancé

Des études récentes ont démontré une augmentation de la prévalence de l’infertilité au Canada ainsi qu’une augmentation fulgurante de l’utilisation de la procréation assistée. Le Québec s’est doté en 2010 d’un programme de financement de la procréation assistée visant un accès universel ainsi que la protection de la santé des mères et des enfants. Les diverses parties prenantes attribuent un certain nombre de lacunes à ce programme, incluant l’absence de mesures de prévention et de promotion de la santé visant à réduire la prévalence de l’infertilité. En effet, une proportion significative de cas d’infertilité découle de facteurs modifiables et relatifs aux modes de vie tels que le tabagisme, les infections transmises sexuellement et par le sang, les problèmes de poids, les toxines environnementales et l’âge. De plus, l’âge maternel avancé ainsi que l’usage de la procréation assistée comportent des risques pour la santé des mères et des enfants au sujet desquels la population ne possède pas une connaissance suffisante. Des approches en amont ont été proposées par diverses organisations et dans divers pays, toutefois, peu ont été adoptées. Force est de constater que ces initiatives représentent de grands défis au point de vue de l’acceptabilité sociale, en raison de la nature sensible du sujet et d’une grande valorisation sociale de l’autonomie reproductive. L’éthique des communications en santé permet d’identifier ces défis qui touchent l’usage de tactiques persuasives, le risque de stigmatisation et l’attribution indue d’une responsabilité. Si leur élaboration tient compte de ces enjeux, les campagnes de communications en santé ont le potentiel d’informer adéquatement la population afin de favoriser l’autonomie et la santé reproductive des individus, sans causer de dommage iatrogénique. L’éthique de l’ « empowerment », qui requiert l’attribution d’une responsabilité individuelle de nature prospective, l’apport de ressources concrètes et l’implication des communautés, permet d’identifier les besoins en termes de solutions législatives favorisant des contextes socioéconomiques qui soutiennent la santé reproductive et l’autonomie reproductive.

Psychosexual aspects of vulvovaginal pain.

Vulvovaginal pain problems are major health concerns in women of childbearing age. Controlled studies have shown that vulvovaginal pain can adversely affect women and their partners’ general psychological well-being, relationship adjustment and overall quality of life. These women have significantly lower levels of sexual desire, arousal, and satisfaction, as well as a lower intercourse frequency than normal controls. They also report more anxiety and depression, in addition to more distress about their body image and genital self-image. Empirical studies indicate that specific psychological and relationship factors may increase vulvovaginal pain intensity and its psychosexual sequelae. Randomized clinical trials have shown that psychosexual interventions, namely cognitive-behavioral therapy (CBT), are efficacious in reducing vulvovaginal pain and improving associated psychosexual outcomes. Women reporting significant psychological, sexual and/or relationship distress should be referred for psychosexual treatment. A multimodal approach to care integrating psychosexual and medical management is thought to be optimal.

Determinantes socio-económicas de la desnutrición global infantil en la Localidad de Ciudad Bolívar (Bogotá, Colombia) en el año 2011

La desnutrición infantil y la pobreza se encuentran asociadas y estas a su vez con el progreso de los países. Conocer las determinantes sociales y económicas de la niñez que padece de bajo peso es necesario para crear escenarios propicios para el adecuado desarrollo de la primera infancia y de esta manera contribuir con la superación de la pobreza en el marco de sistemas sanitarios equitativos. Se realiza una descripción de las características socio-económicas y un análisis de posibles asociaciones entre estas y el bajo peso infantil de una muestra de infantes de uno de los sectores de mayor vulnerabilidad y pobreza de Bogotá (Colombia). La tasa del bajo peso infantil en la muestra del estudio en más alta a la presentada en Bogotá y Colombia (8.5%, 2.9% y 3.4% respectivamente). Al realizar el análisis de las posibles asociaciones entre el bajo peso y las variables de estudio, se evidencia que las relaciones son débiles entre la primera y las segundas, siendo la condición de desplazamiento la que mayor asociación positiva presenta con la deficiencia nutricional seguido del rango de edad entre los 25 y 36 meses. La situación que presenta mayor independencia con respecto al bajo peso infantil es contar con vivienda propia seguida del sexo. La desnutrición infantil se presenta en niveles importantes en sectores de mayor vulnerabilidad con implicaciones para el adecuado desarrollo de los infantes y para las intenciones de reducción de los índices de pobreza en el país. El fortalecimiento de las políticas públicas que favorezca el desarrollo infantil, la superación de la pobreza y las inequidades en los sistemas de salud deben contemplar acciones integrales dirigidas a los más vulnerables, con la participación de la sociedad civil y los sectores públicos y privados, el compromiso político y económico de los gobiernos y reglas claras que contribuyan a la solución estructural de la pobreza y que promueva el adecuado desarrollo infantil.

Asociación de estrés laboral y trastornos hipertensivos en el embarazo

Objetivo: Determinar la prevalencia de trastornos hipertensivos y estrés laboral en las gestantes trabajadoras atendidas en la Clínica Cafam en el mes de noviembre de 2012, y estimar la posible asociación entre estas dos variables. Metodología: Se realizó un estudio de corte transversal. Se incluyeron todas las pacientes gestantes trabajadoras entre 18 y 39 años, con gestación mayor de 20 semanas y feto vivo, sin antecedentes patológicos de importancia, que ingresaron al servicio de hospitalización general y la unidad de cuidado intermedio obstétrico del 1 al 30 de noviembre de 2012 (total de 252). Para medir el nivel de estrés laboral se aplicó una encuesta validada por el Ministerio de Protección social, previo consentimiento informado y se realizó revisión de las historias clínicas para identificar las pacientes con trastornos hipertensivos del embarazo. Resultados: Se incluyeron pacientes de 18 a 39 años encontrando una media de 26.9 años con una desviación estándar de 5,08. 208 pacientes (82.5%) tenían entre 36 y 40 semanas de gestación, 123 maternas cursaban su primera gestación (48.8%) y, la mayoría tienen una relación estable. Respecto al nivel educativo la formación técnica y el bachillerato fueron los más encontrados (38.49% y 35.32% respectivamente). 102 gestantes (40.48%) desempeñan cargos de auxiliar o asistente seguidos de los trabajos operativos en un 30.56% (77 personas). De las 252 pacientes del estudio, 22 maternas tenían hipertensión gestacional, 28 preeclampsia y 1 síndrome HELLP para un total de 20.24% de gestantes con patología. Hay un alto porcentaje de estrés laboral en la población estudiada (40.08%). Al realizar el análisis de los datos se encontró que la probabilidad que tienen las pacientes con algún trastorno hipertensivo de tener estrés laboral es mayor que la de las pacientes que no presentan patología (OR 1.43 con IC 95% de 0.8 a 2.55). Conclusiones. El estrés laboral tiene una alta prevalencia en la población gestante trabajadora y los resultados sugieren que puede ser uno de los factores contribuyentes en la aparición de trastornos hipertensivos en el embarazo.

¿Pluralismo o colonialidad médica? Un estudio alrededor del cáncer en diferentes sistemas médicos colombianos

En esta investigación se realiza un análisis del tipo de relaciones que se establecen entre la medicina alopática y la medicina indígena yagecera en el escenario urbano de Bogotá. Para ello, toma distancia de los estudios ya realizados sobre este tema en el campo de la antropología a partir de dos aspectos: en primer lugar, busca acercarse a esta relación a partir de las trayectorias profesionales de un conjunto de médicos (tanto indígenas como alopáticos); en segundo lugar, se aproxima a estas relaciones a partir de una enfermedad particular: el cáncer.

Narrowing socioeconomic inequality in child stunting: the Brazilian experience, 1974-2007

Objective To assess trends in the prevalence and social distribution of child stunting in Brazil to evaluate the effect of income and basic service redistribution policies implemented in that country in the recent past. Methods The prevalence of stunting (height-for-age z score below 2 using the Child Growth Standards of the World Health Organization) among children aged less than 5 years was estimated from data collected during national household surveys carried out in Brazil in 1974-75 (n = 34 409), 1989 (n = 7374), 1996 (n = 4149) and 2006-07 (n = 4414). Absolute and relative socioeconomic inequality in stunting was measured by means of the slope index and the concentration index of inequality, respectively. Findings Over a 33-year period, we documented a steady decline in the national prevalence of stunting from 37.1% to 7.1%. Prevalence dropped from 59.0% to 11.2% in the poorest quintile and from 12.1% to 3.3% among the wealthiest quintile. The decline was particularly steep in the last 10 years of the period (1996 to 2007), when the gaps between poor and wealthy families with children under 5 were also reduced in terms of purchasing power; access to education, health care and water and sanitation services; and reproductive health indicators. Conclusion In Brazil, socioeconomic development coupled with equity-oriented public policies have been accompanied by marked improvements in living conditions and a substantial decline in child undernutrition, as well as a reduction of the gap in nutritional status between children in the highest and lowest socioeconomic quintiles. Future studies will show whether these gains will be maintained under the current global economic crisis.
