Estado nutricional y características relacionadas en menores de cinco años en la ciudad de Bogotá, 2009

Introducción: La desnutrición infantil es una importante preocupación en países en desarrollo y se relaciona con condiciones de pobreza. Metodología: Estudio secundario de una muestra de 1.232 datos de menores de cinco años con diagnóstico nutricional obtenido en forma retrospectiva en la evaluación del SISVAN año 2009 para Bogotá. Se utilizó para el procesamiento de la información Epi Info 6.04 y SPSS 17.0. Resultados: Se encontró que el 37.2% de los menores está en riesgo de desnutrición, el 27.3% tiene desnutrición aguda y el 7.2% desnutrición crónica. Fontibón y Chapinero presentan la mayor desnutrición aguda y crónica respectivamente. Los menores con reducidos ingresos familiares, de estrato uno, con madres que estudian y trabajan, divorciadas o viudas, o que sean desplazados actuales presentan mayor riesgo de desnutrición. La desnutrición aguda es mayor en los niños con desplazamientos mayores de un año o con esquemas de vacunación incompleto. Cuando se presentan inadecuadas condiciones de saneamiento, peso al nacer inferior a 2000 gramos, madres con escolaridad primaria o grupos etáreos entre 3 y 5 años se observa mayor desnutrición crónica. Quienes reciben lactancia materna exclusiva presentan menor desnutrición aguda y crónica. Conclusiones: En la población estudiada, el riesgo de desnutrición está por encima de la desnutrición aguda y crónica. Los resultados sugieren que la desnutrición y el riesgo de desnutrición pueden ser reducidos mejorando educación materna, saneamiento, prolongando la lactancia y cumpliendo esquemas de vacunación.

Conflict-induced poverty: Evidence from Colombia

En Colombia, la pobreza y el conflicto están estrechamente relacionados. Este estudio usa medidas de disuasión del gobierno como instrumentos de varias variables específicas de conflicto para estimar el impacto del conflicto sobre la pobreza en Colombia. Usando datos del censo a nivel municipal para el año 2005, evalúo el efecto sobre la incidencia urbana y rural del recientemente-desarrollado Índice de Pobreza Multidimensional. Los resultados sugieren que el conflicto aumenta significativamente la pobreza rural. Esto es consistente con el hecho que la mayor parte del conflicto en Colombia ocurre en las áreas rurales. También evalúo el efecto rezagado del conflicto en la pobreza para concluir que éste dura por al menos tres años pero que decae en el tiempo. Finalmente, pruebo que mis resultados son robustos a una batería de especificaciones adicionales, incluyendo una versión modificada de mi variable dependiente y el uso de una base alternativa de conflicto.

Subchronic 3, 4-methylenedioximethamphetamine (mdma) reverts anxiety induced by chronic mild stress

Here we report the effects of subchronic 3, 4-Methylenedioximethamphetamine (MDMA) on the elevated plus-maze, a widely used animal model of anxiety. Rats exposed to a mild chronic stress (MCS) protocol received intracerebroventricular microinjections of the selective serotonin reuptake inhibitor (SSRI) – fluoxetine (2.0ug/ul) or 3, 4-Methylenedioximethamphetamine (MDMA, 2.0ug/ul) for seven days. On the eighth day rats were tested in the elevated plus-maze. Our results showed that sub-chronic MDMA interacted with MCS leading to a decrease in anxiety-related behaviors including: percentage of open arms entries (F[2,26]=4.00; P=0.031), time spent in the open arms (F[2,26]=3.656; P=0.040) and time spent in the open arms extremities (F[2,26]=5.842; P=0.008). These results suggest a potential effect of MDMA in the reversion of the emotional significance of aversive stimuli.

Quality of life and Chronic Obstructive Pulmonary Disease

The Chronic Obstructive Pulmonary Disease (COPD) has a progressive and irreversible character and it’s associated to the triad of dyspnea, exercise limitation and the evident deterioration of quality of life. In the United States the prevalence of COPD in adult population is approximately of 6% in men, and 1 to 3% in women and it’s the fourth cause of mortality by no transmissible chronic diseases. In 1993, the National Health Interview Surgery considered that 12 millions of Americans suffer from chronic bronchitis and 2 million had emphysema. These two affections are responsible for more than 13% of the hospitalizations. As this affection progresses, patients experience a diminution in quality of life related to health (CVRS), their capacity to work get worse and their participation in physical and social activities reduces. Nevertheless, it has been confirmed that the isolated evaluation of COPD seriousness, defined by the reduction of the Forced Expiratory Volume in the First Second (FEV1), does not provide enough information to know the health state perceived by the patients. The fact that the CVRS is the result of the interaction of multiple physical, psychological and social factors, unique for each individual, can explain this finding. This paper is a general and updated approach to the integral handling of patients with COPD, and it discusses the concept of quality of life, related to health improvement.

Poverty impacts of agricultural policy adjustments in an opening economy: the case of Colombia

We aim to contribute to the assessment of poverty impacts on the rural sector arising from agricultural policy adjustments in Colombia. For this we use an agriculture specialized static CGE model, jointly (sequentially) with a microsimulation model that allows for effective job relocation. Results indicate that the sectoral impact of the program implemented tends to be small and has considerable variability across crops. They also show that the highest impacts come from the irrigation and land improvements component of the program. Lastly, although it reduces poverty, poverty impacts are small and tend to concentrate in rural households toward the middle of the income distribution ladder.

Poverty impacts of increased openness and fiscal policies in a dollarized economy: a CGE-micro approach for Ecuador

We quantify the effects on poverty and income distribution in Ecuador of bilateral trade liberalization with the US and a budget-neutral value added tax increase which seeks to compensate tariff revenue losses. We stress the study of fiscal policies that the government could tap in order to compensate for tariff revenue loss. This is a very important issue for Ecuador because this country adopted the US dollar as its currency in 2000, forgiving the use of important policy instruments. To study these issues we combine a reduced-form micro household income and occupational choice model (using 2005/6 data from the Ecuadorian LSMS) with a standard single-country computable general equilibrium model (employing a 2004 SAM). We follow a sequential approach that simulates the full distributional impact of trade and tax policies. We find that the impact of these policy changes on extreme poverty and income distribution is small but positive.

The impact of a minimum pension on old age poverty and its budgetary cost. Evidence from Latin America

This paper examines the impact on old age poverty and the fiscal cost of universal minimum oldage pensions in Latin America using recent household survey data for 18 countries. Alleviatingold age poverty requires different approach from other age groups and a minimum pension islikely to be the only alternative available. First we measure old age poverty rates for all countries.Second we discuss the design of minimum pensions schemes, means-tested or not, as wellas the disincentive effects that they are expected to have on the economic and social behavior ofhouseholds including labor supply, saving and family solidarity. Third we use the household surveysto simulate the fiscal cost and the impact on poverty rates of alternative minimum pensionschemes in the 18 countries. We show that a universal minimum pension would substantiallyreduce poverty among the elderly except in Argentina, Brazil, Chile and Uruguay where minimumpension systems already exist and poverty rates are low. Such schemes have much tobe commended in terms of incentives, spillover effects and administrative simplicity but have ahigh fiscal cost. The latter is a function of the age at which benefits are awarded, the prevailinglongevity, the generosity of benefits, the efficacy of means testing, and naturally the fiscal capacityof the country.
