RESUMO
OBJECTIVE: To determine the effectiveness and degree of implementation of interventions for the control of Aedes aegypti in Latin America and the Caribbean (LAC) as reported in scientific literature. METHODS: We searched MEDLINE, EMBASE, CENTRAL, SOCINDEX, and LILACS, for experimental and observational studies, economic assessments and qualitative experiences carried out in LAC from 2000 to 2016. We assessed incidence and morbimortality of Aedes aegypti-related diseases and entomological indices: Breteau (containers), House, and Pupae per Person. We used GRADE methodology for assessing quality of evidence. RESULTS: Of 1826 records retrieved, 75 were included and 9 cluster randomised clinical trials could be meta-analysed. We did not identify any intervention supported by a high certainty of evidence. In consistency with qualitative evidence, health education and community engagement probably reduces the entomological indices, as do the use of insecticide-treated materials, indoor residual spraying and the management of containers. There is low certainty of evidence supporting the use of ovitraps or larvitraps, and the integrated epidemiological surveillance strategy to improve indices and reduce the incidence of dengue. The reported degree of implementation of these vector control interventions was variable and most did not extend to whole cities and were not sustained beyond 2 years. CONCLUSIONS: We found a general lack of evidence on effectiveness of vector control in the region, despite a few interventions that showed moderate to low certainty of evidence. It is important to engage and educate the community, apart from achieving the implementation of integrated actions between the health and other sectors at national and regional level.
OBJECTIF: Déterminer l'efficacité et le degré d'implémentation des interventions de lutte contre Aedes aegypti en Amérique latine et dans les Caraïbes (ALC), tels que décrits dans la littérature scientifique. MÉTHODES: Nous avons effectué des recherches dans MEDLINE, EMBASE, CENTRAL, SOCINDEX et LILACS pour des études expérimentales et d'observation, des évaluations économiques et des expériences qualitatives réalisées dans la région ALC de 2000 à 2016. Nous avons évalué l'incidence et la morbimortalité des maladies liées à Aedes aegypti et les indices entomologiques: Breteau (conteneurs), Maison et Pupe par Personne. Nous avons utilisé la méthodologie GRADE pour évaluer la qualité des données. RÉSULTATS: Sur 1.826 articles retrouvés, 75 ont été inclus et 9 essais cliniques randomisés en grappes ont pu être méta-analysés. Nous n'avons identifié aucune intervention étayée par une certitude élevée. De manière cohérente avec les preuves qualitatives, l'éducation pour la santé et la participation de la communauté réduisent probablement les indices entomologiques, de même que l'utilisation de matériaux traités à l'insecticide, la pulvérisation de résidus à l'intérieur et la gestion des conteneurs. Il existe peu de certitude quant aux données soutenant l'utilisation des ovitraps ou des larvitraps et de la stratégie de surveillance épidémiologique intégrée visant à améliorer les indices et à réduire l'incidence de la dengue. Le degré d'implémentation rapporté pour ces interventions de lutte antivectorielle était variable et la plupart ne s'étendaient pas à l'entièreté des villes et ne duraient pas plus de deux ans. CONCLUSIONS: Nous avons constaté un manque général de preuves sur l'efficacité de la lutte antivectorielle dans la région, malgré quelques interventions montrant une certitude modérée à faible. Il est important d'impliquer et d'éduquer la communauté, outre la mise en Åuvre d'actions intégrées entre le secteur de la santé et d'autres secteurs aux niveaux national et régional.

RESUMEN Antecedentes Al momento no se ha logrado sintetizar toda la información cuali-cuantitativa relacionada al control de Aedes aegypti (A. aegypti) en América Latina y el Caribe (ALC). Objetivo Describir la existencia y el grado de ejecución de los programas específicos o actividades de control vectorial en ALC como parte de programas sanitarios, establecer los costos y/o costoefectividad de las estrategias de control vectorial e identificar barreras y facilitadores para la implementación de las estrategias. Métodos El estudio se llevará a cabo en dos fases complementarias. La primera fase será cuantitativa en la forma de una revisión sistemática, cuyos detalles han sido publicados en la base PROSPERO (CRD42016038067). La segunda fase será cualitativa y consistirá en la realización de entrevistas en profundidad semiestructuradas a informantes clave como investigadores, responsables programáticos,referentes nacionales, agentes del sistema sanitario y representantes de organizaciones no gubernamentales. Discusión El abordaje cualicuantitativo permitirá describir las estrategias y el nivel de implementación para el control de vector y su efectividad, sus costos programáticos y costo-efectividad. Permitirá también analizar factores influyentes en la implementación de programas.

OBJECTIVE: Determine the relationship between tobacco-use prevalence and smoker income level in Latin America and the Caribbean (LAC). METHODS: A systematic search was carried out in MEDLINE, EMBASE, CENTRAL, SOCINDEX, and LILACS databases. Studies from LAC published from January 1989 to December 2015 were included and were analyzed by subgroups disaggregated by decade of data, country, bias risk, sex, and age group. RESULTS: Of 1 254 studies evaluated by full text, 29 articles were included, of which 25 were chosen for meta-analysis. All included studies were cross-sectional or surveillance, primarily from Brazil and Mexico.Low income was associated with higher prevalence of active smoking (odds ratio [OR] 1.62; 95% confidence interval [95%CI] 1.34-1.96) than high income (reference). A dose-response effect trend was observed: middle income (OR 1.23; 95%CI 1.00-1.52) and low income (OR 1.64; 95%CI 1.17-2.30). This association was greater in men (OR 2.22; 95%CI 1.77-2.78) than in women (OR 1.6; 95%CI 1.11-2.47). CONCLUSIONS: An inverse relationship was observed between income and tobacco-use prevalence. Further efforts are required to determine this relationship in special populations, such as adolescents and pregnant women. This research can be useful for policymakers by improving tobacco control strategies and for characterizing public health equity issues.

RESUMEN Objetivo Determinar la relación entre la prevalencia de consumo actual de tabaco y los niveles de ingresos monetarios de fumadores en América Latina y el Caribe (ALC). Métodos Se realizó una búsqueda sistemática en bases de datos incluyendo MEDLINE, EMBASE, CENTRAL, SOCINDEX y LILACS. Se incluyeron estudios de ALC publicados desde enero 1989 hasta diciembre de 2015. Se realizaron análisis de subgrupos planeados por década calendario de los datos, país, riesgo de sesgo, sexo y grupos de edad. Resultados De un total de 1 254 estudios evaluados por texto completo se incluyeron 29 artículos, de los cuales 25 fueron incorporados en metaanálisis. Todos los estudios incluidos fueron de corte transversal o de vigilancia, la mayoría provenientes de Brasil y de México. Un bajo nivel de ingresos se asoció con una mayor prevalencia de tabaquismo activo (odds ratio [OR] 1,62; intervalo de confianza de 95% [IC95%] 1,34–1,96) con respecto al nivel alto (referencia). Se observó una tendencia de efecto dosis-respuesta: nivel medio de ingresos (OR 1,23; IC95% 1,00-1,52) y nivel bajo de ingresos (OR 1,64; IC95% 1,17-2,30). Esta asociación fue mayor en hombres (OR 2,22; IC95% 1,77-2,78) que en mujeres (OR 1,6; IC95% 1,11-2,47). Conclusiones Se observó una relación inversa entre el nivel de ingresos y la prevalencia de consumo de tabaco. Se requieren mayores esfuerzos para determinar esta relación en poblaciones especiales como adolescentes o embarazadas. Esta investigación puede ser útil para los decisores políticos al mejorar las estrategias de control del tabaco y para caracterizar cuestiones de equidad en la salud pública.
