The objective of this research was to identify environmental risk factors for cutaneous leishmaniasis (CL) in Colombia and map high-risk municipalities. The study area was the Colombian Andean region, comprising 715 rural and urban municipalities. We used 10 years of CL surveillance: 2000-2009. We used spatial-temporal analysis - conditional autoregressive Poisson random effects modelling - in a Bayesian framework to model the dependence of municipality-level incidence on land use, climate, elevation and population density. Bivariable spatial analysis identified rainforests, forests and secondary vegetation, temperature, and annual precipitation as positively associated with CL incidence. By contrast, livestock agroecosystems and temperature seasonality were negatively associated. Multivariable analysis identified land use - rainforests and agro-livestock - and climate - temperature, rainfall and temperature seasonality - as best predictors of CL. We conclude that climate and land use can be used to identify areas at high risk of CL and that this approach is potentially applicable elsewhere in Latin America.
Resumen Las enfermedades cardiovasculares (ECV) son la principal causa de muerte en el mundo y en Colombia siendo consideradas un serio problema de salud pública. El objetivo de este estudio fue analizar espacial y temporalmente la mortalidad por ECV en la región Pacifico de Colombia durante el periodo 2002-2015 y su asociación con algunos indicadores socioeconómicos municipales usando técnicas estadísticas de análisis espacial. Fue un estudio descriptivo-ecológico en los 177 municipios de la región Pacifico que usó datos de mortalidad por ECV, bajo los códigos I00-I99 de la Clasificación Internacional de Enfermedades (CIE-10), y siete indicadores socioeconómicos municipales. El análisis incluyó cálculo de tasas de mortalidad crudas y estandarizadas, según sexo, para las ECV y sus principales causas, y la modelación del conteo de defunciones usando modelos jerárquicos Bayesianos. Durante el periodo 2002-2015 las tasas estandarizadas de mortalidad por ECV mostraron una tendencia descendente en hombres (129,0 a 119,3) y en mujeres (129,0 a 110,0) siendo las principales causas de muerte las enfermedades isquémicas del corazón, seguidas de las cerebrovasculares. En general, el riesgo de mortalidad por ECV fue mayor en los municipios menos favorecidos económica y socialmente.
Objective: To describe the profile and trend of overall and cause-specific mortality, during the period 2002-2014, of the departments of the Pacific region of Colombia: Cauca, Chocó, Nariño and Valle del Cauca. Methodology: Descriptiveecological study that uses secondary data on mortality, births and population projections from the National Administrative Department of Statistics (dane). Annual overall and causespecific mortality rates were calculated (by age, sex and for six large groups of causes of death), using the short list of causes of death 6/67 of the Pan American Health Organization (paho) (communicable diseases, neoplasms/tumors, diseases of the circulatory system, conditions originating in the perinatal period, external causes and other causes). Trends were evaluated using a Poisson regression model with random effects. Results: Higher mortality was found in males (male/female ratio between 1.26-1.61) and in the population over 65 years of age. A downward trend was observed in overall mortality in the four departments, with Valle del Cauca having the highest overall and causespecific mortality rates. The main cause of death, and with an upward trend, were diseases of the circulatory system, followed by other causes, external causes and neoplasms. Conclusions: Overall mortality showed a downward trend, of greater magnitude in men, and differential risk according to sex from 15-19 years attributed to the group of external causes. The main cause of death was diseases of the circulatory system, followed by all other causes and neoplasms. External causes showed a marked downward trend.
<p class="Pa12"><span class="A4"><span>Este estudio tuvo como objetivo analizar la mortalidad por VIH/sida en Cali, Colombia, en el periodo 1986-2012, y a partir de ahí, comprender, desde el punto de vista conceptual, los determinantes sociales relacionados. Se llevó a cabo un estudio observacional, longitudinal, retrospectivo, con un total de 14 192 casos. Se encontró una tendencia creciente de la tasa de mortalidad, en especial a partir del año 1996; en el 2011 se presentó la mayor tasa de todo el periodo. La medición de la desigualdad reveló que se han producido más muertes en estratos medios y bajos, en comparación con el estrato alto. Este estudio aporta evidencia sobre las desigualdades persistentes en la mortalidad por VIH/sida como expresión de inequidades de tipo estructural en la ciudad de Cali. En la perspectiva de Breilh, son procesos críticos de determinación económica y social que pudieron afectar la mortalidad, especialmente de los grupos con más vulnerados socialmente. </span></span></p>
