Zika virus epidemiology in Bolivia: A seroprevalence study in volunteer blood donors.

Saba Villarroel, Paola Mariela; Nurtop, Elif; Pastorino, Boris; Roca, Yelin; Drexler, Jan Felix; Gallian, Pierre; Jaenisch, Thomas; Leparc-Goffart, Isabelle; Priet, Stéphane; Ninove, Laetitia; de Lamballerie, Xavier

BACKGROUND: Zika virus (ZIKV), was widely reported in Latin America and has been associated with neuropathologies, as microcephaly, but only few seroprevalence studies have been published to date. Our objective was to determine the seroprevalence amongst Bolivian blood donors and estimate the future potential circulation of the virus. METHODOLOGY: A ZIKV seroprevalence study was conducted between December 2016 and April 2017 in 814 asymptomatic Bolivian volunteer blood donors residing in various eco-environments corresponding to contrasting entomological activities. It was based on detection of IgG to ZIKV using NS1 ELISA screening, followed by a seroneutralisation test in case of positive or equivocal ELISA result. CONCLUSIONS/SIGNIFICANCE: Analysis revealed that ZIKV circulation occurred in tropical areas (Beni: 39%; Santa Cruz de la Sierra: 21.5%) but not in highlands (~0% in Cochabamba, La Paz, Tarija). It was modulated by Aedes aegypti activity and the virus spread was not limited by previous immunity to dengue. Cases were geo-localised in a wide range of urban areas in Santa Cruz and Trinidad. No differences in seroprevalence related to gender or age-groups could be identified. It is concluded that ZIKV has been intensely circulating in the Beni region and has still a significant potential for propagating in the area of Santa Cruz.

Factores socioeconómicos y zona de residencia como estratificadores de desigualdades en salud en Bolivia

Alarcon, Wilson René
| Idioma(s): Español
Objetivo. Describir las desigualdades en salud respecto a indicadores de cobertura estratificado por factores socioeconómicos y lugar de residencia. Métodos. Se realizó un estudio ecológico con datos de las Encuestas de Demografía y Salud 2003, 2008 y la Encuesta Nacional de Salud y Nutrición 2012. Con un análisis de 15 variables respecto a estratificadores socioeconómicos y de lugar de residencia. Resultados. El Índice Compuesto de Cobertura (ICC) calculado mostró que los grupos más pobres se han acercado a los grupos más ricos reduciendo la brecha de desigualdad, el cambio en los quintiles más ricos no ha sido tan acelerado como en los quintiles más pobres. Varios de los indicadores han tenido avances más acelerados para el grupo más pobre como el de partos atendidos por personal de salud, otros indicadores han presentado condiciones de crecimiento reducido en la disminución de la desigualdad. La desnutrición crónica en niños menores de 5 años ha disminuido, sin embargo, la anemia en el mismo grupo de edad se ha incrementado. Conclusiones. Los indicadores mostraron avances en la reducción de la desigualdad y disminución en la brecha entre los grupos más pobres y los más ricos. El uso de métodos de planificación familiar, por la presencia de bonos de transferencia condicionada podría no haber logrado el crecimiento esperado. Se deben evaluar estrategias como la suplementación con hierro a niños menores de 5 años, que ha crecido en la provisión del suplemento, pero no ha tenido impacto en la reducción de la anemia. Objective. Describe health inequalities with regard to coverage indicators stratified by socioeconomic factors and place of residence. Methods. An ecological study was conducted with data from the 2003 and 2008 Demographic and Health Surveys and the 2012 National Health and Nutrition Survey, with analysis of 15 variables for socioeconomic and place-of-residence stratifiers. Results. Calculation of the composite coverage index showed that the poorest groups have moved closer to the richest groups, bridging the inequality gap; change in the richest quintiles has not been as rapid as in the poorest quintiles. Several of the indicators have seen more rapid progress in the poorest group, such as that for deliveries attended by health personnel; other indicators showed reduced growth in reduction of inequality. Chronic malnutrition in children under 5 has decreased; however, anemia in this age group has increased. Conclusions. The indicators showed advances in reduction of inequality and reduction in the gap between the poorest and richest groups. Expected growth in the use of family planning methods may not have been reached because of the existence of conditional cash transfers. Strategies should be evaluated, such as iron supplementation in children under 5, where provision of the supplement has increased, but it has not had an impact on anemia reduction. Objetivo. Descrever as desigualdades em saúde segundo indicadores de cobertura estratificados por fatores socioeconômicos e área de residência. Métodos. Foi realizado um estudo ecológico com dados obtidos das Pesquisas de Demografia e Saúde de 2003 e 2008 e da Pesquisa Nacional de Saúde e Nutrição de 2012 baseado na análise de 15 variáveis relacionadas a variáveis de estratificação por fatores socioeconômicos e área de residência. Resultados. O índice de cobertura composto (ICC) calculado demonstrou que os estratos de menor renda estão mais próximos aos estratos de maior renda, diminuindo o hiato de desigualdade, mas a mudança nos quintis de maior renda não foi tão acelerada como nos quintis de menor renda. Observou-se progresso mais acentuado em vários indicadores no estrato de menor renda como o número de partos assistidos por profissionais da saúde, mas pouco avanço em outros indicadores para reduzir as desigualdades. Em crianças menores de cinco anos, o número de casos de desnutrição crônica diminuiu, mas de anemia aumentou. Conclusões. Os indicadores apontam avanços na redução da desigualdade em saúde, com menor hiato entre os estratos de menor e maior renda. O uso de métodos de planejamento familiar, como parte de programa de transferência de renda condicionada, possivelmente não teve o crescimento esperado. Algumas estratégias precisam ser reavaliadas, por exemplo a suplementação de ferro em crianças menores de cinco anos: houve um aumento na provisão de ferro, porém ele não surtiu efeito na redução da anemia.

RESUMEN Objetivo Estimar los costos médicos directos atribuibles al tabaquismo en los sistemas de salud de América Latina. Métodos Se utilizó un modelo de microsimulación para cuantificar el impacto económico en enfermedad cardiovascular y cerebrovascular, enfermedad pulmonar obstructiva crónica (EPOC), neumonía, cáncer de pulmón y otras nueve neoplasias. Se realizó una búsqueda sistemática de datos epidemiológicos y de costos de los eventos. El modelo se calibró y validó para Argentina, Bolivia, Brasil, Chile, Colombia, México y Perú, países que representan el 78% de la población de América Latina; luego se extrapolaron los resultados a nivel regional. Resultados Cada año el tabaquismo es responsable de 33 576 millones de dólares en costos directos para el sistema de salud. Esto equivale a 0,7% del producto interno bruto (PIB) de la región y a 8,3% del presupuesto sanitario. La enfermedad cardiovascular, la EPOC y el cáncer fueron responsables de 30,3%, 26,9% y 23,7% de este gasto, respectivamente. El costo atribuible al tabaquismo varió entre 0,4% (México y Perú) y 0,9% (Chile) del PIB y entre 5,2% (Brasil) y 12,7% (Bolivia) del gasto en salud. En la región, la recaudación impositiva por la venta de cigarrillos apenas cubre 37% del gasto sanitario atribuible al tabaquismo (8,1% en Bolivia y 67,3% en Argentina). Conclusiones El tabaquismo es responsable de una importante proporción del gasto sanitario en América Latina, y la recaudación impositiva por la venta de cigarrillos está lejos de llegar a cubrirlo. La profundización de medidas como el aumento de impuestos al tabaco debería ser seriamente considerada por los países de la región. ABSTRACT Objective Estimate smoking-attributable direct medical costs in Latin American health systems. Methods A microsimulation model was used to quantify financial impact of cardiovascular and cerebrovascular disease, chronic obstructive pulmonary disease (COPD), pneumonia, lung cancer, and nine other neoplasms. A systematic search for epidemiological data and event costs was carried out. The model was calibrated and validated for Argentina, Bolivia, Brazil, Chile, Colombia, Mexico, and Peru, countries that account for 78% of Latin America’s population; the results were then extrapolated to the regional level. Results Every year, smoking is responsible for 33 576 billion dollars in direct costs to health systems. This amounts to 0.7% of the region’s gross domestic product (GDP) and 8.3% of its health budget. Cardiovascular disease, COPD, and cancer were responsible for 30.3%, 26.9%, and 23.7% of these expenditures, respectively. Smoking-attributable costs ranged from 0.4% (Mexico and Peru) to 0.9% (Chile) of GDP and from 5.2% (Brazil) to 12.7% (Bolivia) of health expenditures. In the region, tax revenues from cigarette sales barely cover 37% of smoking-attributable health expenditures (8.1% in Bolivia and 67.3% in Argentina). Conclusions Smoking is responsible for a significant proportion of health spending in Latin America, and tax revenues from cigarette sales are far from covering it. The region’s countries should seriously consider stronger measures, such as an increase in tobacco taxes.

Hunger and Behavioral Risk Factors for Noncommunicable Diseases in School-Going Adolescents in Bolivia, 2012.

Romo, Matthew L
| Idioma(s): Inglés
Hunger may play a role in noncommunicable disease (NCD) risk. This study used the 2012 Global School-based Student Health Survey from Bolivia to determine the association between hunger and risk factors for NCDs among adolescents. Hunger was associated with increased odds of nondaily fruit and vegetable consumption (adjusted odds ratio [AOR] = 1.21; P < .001), inadequate physical activity (AOR = 1.21; P = .001), and current tobacco use (hunger sometimes [AOR = 1.83; P < .001] or most of the time/always [AOR = 2.12; P < .001]). Interventions to reduce the burden of NCDs in Bolivia should address hunger, in addition to traditional behavioral risk factors.

Different Patterns in Health Care Use Among Immigrants in Spain.

Villarroel, Nazmy; Artazcoz, Lucía
| Idioma(s): Inglés
This study aims to analyze the differences in the use of primary care (PC), hospital, and emergency services between people born in Spain and immigrants. Data were obtained from the 2006 Spanish National Health Survey. The sample was composed of individuals aged 16-64 years from Spain and the seven countries with most immigrants in Spain (n = 22,224). Hierarchical multiple logistic regression models were fitted. Romanian men were less likely to use health care at all levels compared to men from other countries. Women from Argentina, Bolivia and Ecuador reported a lower use of PC. Among women, there were no differences in emergency visits or hospitalizations between countries. Bolivian men reported more hospitalizations than Spanish men, whereas Argentinean men reported more emergency visits than their Spanish counterparts. In Spain, most immigrants made less than, or about the same use of health care services as the native Spanish population.

The effects of community income inequality on health: Evidence from a randomized control trial in the Bolivian Amazon.

Undurraga, Eduardo A; Behrman, Jere R; Leonard, William R; Godoy, Ricardo A
| Idioma(s): Inglés
Research suggests that poorer people have worse health than the better-off and, more controversially, that income inequality harms health. But causal interpretations suffer from endogeneity. We addressed the gap by using a randomized control trial among a society of forager-farmers in the Bolivian Amazon. Treatments included one-time unconditional income transfers (T1) to all households and (T2) only to the poorest 20% of households, with other villages as controls. We assessed the effects of income inequality, absolute income, and spillovers within villages on self-reported health, objective indicators of health and nutrition, and adults' substance consumption. Most effects came from relative income. Targeted transfers increased the perceived stress of participants in better-off households. Evidence suggests increased work efforts among better-off households when the lot of the poor improved, possibly due to a preference for rank preservation. The study points to new paths by which inequality might affect health.

Progress in reducing inequalities in reproductive, maternal, newborn,' and child health in Latin America and the Caribbean: an unfinished agenda/ Avances en la reducción de las desigualdades en materia de salud reproductiva, materna, neonatal e infantil en América Latina y el Caribe: un programa inacabado

Restrepo-Méndez, María Clara; Barros, Aluísio J. D.; Requejo, Jennifer; Durán, Pablo; Serpa, Luis Andrés de Francisco; França, Giovanny V. A.; Wehrmeister, Fernando C.; Victora, Cesar G.

OBJECTIVE: To expand the "Countdown to 2015" analyses of health inequalities beyond the 75 countries being monitored worldwide to include all countries in Latin America and the Caribbean (LAC) that have adequate data available. METHODS: Demographic and Health Surveys and Multiple Indicator Cluster Surveys were used to monitor progress in health intervention coverage and inequalities in 13 LAC countries, five of which are included in the Countdown (Bolivia, Brazil, Guatemala, Haiti, and Peru) and eight that are not (Belize, Colombia, Costa Rica, Dominican Republic, Guyana, Honduras, Nicaragua, and Suriname). The outcomes included neonatal and under-5 year mortality rates, child stunting prevalence, and the composite coverage index-a weighted average of eight indicators of coverage in reproductive, maternal, newborn, and child health. The slope index of inequality and concentration index were used to assess absolute and relative inequalities. RESULTS: The composite coverage index showed monotonic patterns over wealth quintiles, with lowest levels in the poorest quintile. Under-5 and neonatal mortality as well as stunting prevalence were highest among the poor. In most countries, intervention coverage increased, while under-5 mortality and stunting prevalence fell most rapidly among the poor, so that inequalities were reduced over time. However, Bolivia, Guatemala, Haiti, Nicaragua, and Peru still show marked inequalities. Brazil has practically eliminated inequalities in stunting. CONCLUSIONS: LAC countries presented substantial progress in terms of reducing inequalities in reproductive, maternal, newborn, and child health interventions, child mortality, and nutrition. However, the poorest 20% of the population in most countries is still lagging behind, and renewed actions are needed to improve equity. OBJETIVO: Extender los análisis de la "Cuenta Regresiva para 2015" de las desigualdades en materia de salud más allá de los 75 países sometidos a vigilancia en todo el mundo para incluir a todos los países de América Latina y el Caribe (ALC) que disponen de datos adecuados. MÉTODOS: Se utilizaron encuestas de demografía y salud y encuestas agrupadas de indicadores múltiples para vigilar el progreso de la cobertura de las intervenciones de salud y de las desigualdades en 13 países de ALC, 5 de ellos incluidos en la Cuenta Regresiva (Bolivia, Brasil, Guatemala, Haití y Perú) y 8 no incluidos (Belice, Colombia, Costa Rica, Guyana, Honduras, Nicaragua, República Dominicana y Suriname). Los resultados incluyeron las tasas de mortalidad neonatal y en menores de 5 años, la prevalencia del retraso del crecimiento en niños y el índice compuesto de cobertura (un promedio ponderado de 8 indicadores de cobertura en materia de salud reproductiva, materna, neonatal e infantil. Para evaluar las desigualdades absolutas y relativas, se emplearon el índice de desigualdad de la pendiente y el índice de concentración. RESULTADOS: El índice compuesto de cobertura mostró patrones monotónicos en función de los quintiles de riqueza, con los niveles más bajos en el quintil más pobre. La mortalidad neonatal y en menores de 5 años, así como la prevalencia del retraso del crecimiento, fueron más elevadas entre los pobres. En la mayor parte de los países aumentó la cobertura de las intervenciones, mientras que la mortalidad en menores de 5 años y la prevalencia del retraso del crecimiento disminuyeron más rápidamente entre los pobres, de manera que las desigualdades se redujeron con el transcurso del tiempo. Sin embargo, en Bolivia, Guatemala, Haití, Nicaragua y Perú aún se observan marcadas desigualdades. Brasil prácticamente ha eliminado las desigualdades en cuanto a retraso del crecimiento. CONCLUSIONES: Los países de ALC mostraron avances considerables en la reducción de las desigualdades con respecto a las intervenciones de salud reproductiva, materna, neonatal e infantil, y en materia de mortalidad y nutrición infantil. Sin embargo, el 20% más pobre de la población en la mayor parte de los países sigue quedándose a la zaga, y son necesarias iniciativas renovadas para mejorar la equidad.

Este libro representa un trabajo pionero sobre las condiciones en las que mujeres de pueblos indígenas en Bolivia, confrontan sus problemas de salud, en un escenario marcado por carencias institucionales y tratos discriminatorios asentados en los servicios existentes. El libro, producido en el marco de una intensa interacción reflexiva entre las investigadoras, también hace referencia a las formas culturales que le son propias a las poblaciones indígenas y sobre las cuales se han erigido concepciones particulares acerca de la vinculación entre humanidad y naturaleza, en este caso fuertemente enfocada a la salud materna. En ese sentido, el libro ofrece referencias fundamentales para nutrir la visión intercultural, la misma que adquiere connotaciones propias cuando se trata de la salud de las mujeres, atrapadas en el entretejido complejo que supone la relación entre tradición y modernidad y la disyuntiva entre derechos culturales y universalismo.
