Mortalidad por lesiones de tránsito en adultos mayores en la República de Ecuador entre los años 1990 y 2018: estudio descriptivo

The present study aimed to estimate the trend in road traffic injury mortality in older adults (60 years of age or older) and comparison with those <60 years of age in Ecuador (1990-2018). Official death records and population projections were used to calculate mortality rates per 100,000 population, rate ratios, years of potential life lost (YPLL), and trends. Those under 60 years of age had mortality rates of 16.7 (per 100,000) compared to 36.2 (per 100,000) for older adults, with an increasing trend in YPLL. Older adults recorded fewer deaths than the younger population. However, it is necessary to develop road safety strategies oriented to the progressive aging of the Ecuadorian population.

Health inequity in workers of Latin America and the Caribbean

Latin America and the Caribbean (LAC) is the world’s most inequitable region in terms of wealth distribution. The full scale of social inequalities in health has been hidden by the lack of reliable data. This study aimed to measure and compare health inequalities in the working population within and between 15 countries of LAC

Occupational safety and health in Ecuador

Background: The occupational safety and health diagnostic (OSH) constitutes a first step for the design of national programs and ongoing reviews of existing regulations.  The OSH diagnostic performed in Ecuador in 2011 is devastating due to the high labor accidents toll, the scarce official information, lack of high-level academic education, and insufficient research. Objective: To diagnose the current state of occupational safety and health in Ecuador from official sources of information. Methods: We examined the geographical situation, sociodemographic and public health data, legal regulations, statistics on occupational accidents and diseases, training and research on OSH in Ecuador between 2010 to 2015. The main sources of data and information were: national laws and regulations on OSH, conventions of the International Labor Organization, resolutions of the Andean Community of Nations, and official web pages of national public bodies. In addition, we analyzed the scientific production on OSH of authors with Ecuadorian affiliation, carried out in Ecuador, and published in journals indexed in the main scientific databases. Results: In Ecuador, the rate of employment is 94,3%, and 40% is recognized as adequate employment. The percentage of the working population covered by the social security has raised during the period of study, but it remains around 42% of this population. The country has ratified the 32 ILO OSH conventions and has adopted regional regulatory instruments. The national OSH legal body starts with the Constitution. A total of 99.156 occupational injuries and 2.733 occupational were notified, showing a significant increase from 2010 to 2015. Regarding fatal occupational accidents, 1.524 cases were notified. Training in OSH is focused on occupational risk prevention. Twelve scientific articles on OSH from authors of Ecuadorian affiliation and developed in a national context were identified. Conclusions: OSH status in Ecuador faces a persistent high toll of informal workers, an aging working population, an increase of work accidents, a scarce scientific evidence and an outdated legislation. The design of a OSH National Plan should become a priority in order to improve working conditions and health in Ecuador

Intervención psicosocial preventiva de estrés laboral y abuso en el consumo de alcohol en una empresa venezolana

  A descriptive, longitudinal, field and correlational investigation was carried out in the working population of a Venezuelan company. In order to prevent, through psychosocial intervention, negative effects generated by work stress and alcohol consumption abuse. The sample consisted of 127 workers from the operational area, who were given the questionnaire from the Universidad Astral de Chile for work stress and the AUDIT test. 29 workers with occupational stress and 43 with alcohol consumption abuse were identified, from which, only 11 exhibited both variables simultaneously, a sine qua non condition to perform the intervention. Therefore, the CoPsoQ 21 questionnaire was applied and the intervention was performed using expository methods as well as group and individual discussion with the relevant monitoring and observation. Once the intervention was completed, the corresponding impact on the workers was evaluated. Data were analyzed by using descriptive statistics. In conclusion, the level of work stress was reduced as the dimensions of emotional exhaustion and depersonalization continued at the low level and the personal achievement dimension was at the middle level. Regarding alcohol abuse, there was a reduction in the consumption of risk and harmful consumption. Likewise, CoPsoQ istas 21 showed that the dimensions of psychosocial requirements and double presence were within the most favorable level for health, the compensation dimension at the intermediate level and the rest of the dimensions social support in the company and quality of leadership and work active and professional development possibilities showed a more unfavorable level for health. The relationship between the variables labor stress and alcohol consumption was determined with the Spearman coefficient, whose results brought up 0.21, showing a direct, weak and positive relationship.Key words:  stress, work stress, alcohol abuse, alcohol dependency.  Con el objetivo de prevenir, mediante intervención psicosocial, efectos negativos generados por el Estrés Laboral y los Trastornos por el Consumo de Alcohol, se realizó investigación descriptiva, longitudinal, de campo y correlacional en una empresa venezolana. La muestra estuvo constituida por 127 trabajadores del área operativa, a quienes se les aplicó el cuestionario de la Universidad Astral de Chile para Estrés Laboral y el test AUDIT para Consumo de Alcohol. Se identificaron 29 trabajadores con Estrés Laboral y 43 con trastornos por Consumo de Alcohol, respectivamente, de los que solo 11 exhibieron simultáneamente ambas variables, condición sine qua non para ejecutar la intervención. Además, a estos 11 trabajadores se les aplico el cuestionario CoPsoQ istas 21 y se realizó la intervención previa validación de expertos en el área, utilizando métodos expositivos y de discusión grupal e individual con la pertinente vigilancia y observación. Posteriormente, se evaluó el impacto correspondiente en los trabajadores. Los datos obtenidos se analizaron mediante la estadística descriptiva. En conclusión, el nivel de Estrés Laboral se redujo por cuanto las dimensiones Agotamiento Emocional y Despersonalización continuaron en el nivel bajo y la dimensión Logros personales se ubicó en el nivel medio. Con respecto a los Trastornos por Consumo de alcohol, se observó reducción en el consumo de riesgo y consumo perjudicial. Asimismo, se evidenció que las dimensiones exigencias psicosociales y doble presencia estuvieron dentro del nivel más favorable para la salud, la dimensión compensación en el nivel intermedio y el resto de las dimensiones apoyo social en la empresa y calidad de liderazgo y trabajo activo y posibilidades de desarrollo profesional evidenció un nivel más desfavorable para la salud. La relación entre las variables Estrés Laboral y Trastornos por el Consumo de Alcohol mostró una relación positiva, directa y débil. Palabras clave: estrés, estrés laboral, trastornos por el consumo de alcohol, dependencia de alcohol

I Encuesta sobre Seguridad y Salud en el Trabajo en Quito: siniestralidad laboral

The objective of this article is to describe the occupational accident profiles from a socio-demographic and labor perspective through the results of the First Survey on Occupational Health and Safety Conditions conducted in Quito, Ecuador. The variables on work accidents included in the occupational health dimension are analyzed from the descriptive and inferential point of view (chi-square). 13% of the surveyed workers reported having suffered an accident at work in the last year, mainly men between the ages of 25 to 55 and more than 9 years in the company. Agriculture, livestock, forestry and fishing are the economic activities with greater occupational accidents. Men from the age of 35 years have greater accidents recidivism. The results of this first study show the need to formulate new policies on occupational safety and health.Este artículo tiene por objetivo describir los perfiles de siniestralidad laboral desde un enfoque socio-demográfico y laboral a través de los resultados de la Primera Encuesta sobre Condiciones de Seguridad y Salud en el Trabajo aplicada en Quito, Ecuador.

Monitoring Self-Perceived Occupational Health inequities in Central america, 2011 and 2018

Objectives. to analyze changes in occupational health inequity between 2011 and 2018 among workers in Central America. Methods. Data were collected by face-to-face interviews at the workers\u27 homes for the 2 Central America Working Conditions Surveys (n = 12 024 in 2011 and n = 9030 in 2018). We estimated health inequity gaps by means of absolute and relative population attributable risks and the weighted Keppel index. We stratified all analyses by gender. Results. Between 2011 and 2018, the proportion of workers reporting poor self-perceived health decreased both in women (from 32% to 29%) and men (from 33% to 30%). However, the health inequity gaps remained wide in the 4 stratifiers. Measured by the Keppel index, health inequity gaps between countries increased from 22% to 39% in women and from 20% to 29% in men. Conclusions. While health improved between 2011 and 2018, health inequity gaps remained wide. Wider health inequity gaps were observed between countries than by gender, age, occupation, or education. Public Health Implications. This first benchmark of occupational health inequities in Central America could be useful when developing and evaluating the impact of public policies on work

Jornadas laborales prolongadas y lesiones por accidentes de trabajo: estimaciones de la Primera Encuesta sobre Condiciones de Seguridad y Salud en el Trabajo en Ecuador

Objetivo: estimar la relación entre las jornadas de trabajo por semana y las lesiones por accidente de trabajo (LAT) en la población asalariada de la ciudad ecuatoriana de Guayaquil.  Métodos: estudio transversal que empleó datos de la Primera Encuesta de Condiciones de Seguridad y Salud en el Trabajo para el Ecuador en 2017. Los encuestados fueron 1 005 trabajadores asalariados y se dividieron en dos grupos según las horas de trabajo semanales, ?43 y ?44 horas. La relación entre las jornadas laborales prolongadas y LAT por sexo se analizó mediante regresión logística (OR; IC95%) ajustado por características sociodemográficas (Modelo 1) y añadiendo las ocupacionales (Modelo 2). Resultados: El 30,9% de los trabajadores declaró trabajar 44 horas o más a la semana (50,7±6,3 horas) y la frecuencia de LAT en este grupo fue superior en los hombres (24,2%) respecto a las mujeres (12%). Las LAT en jornadas laborales prolongadas aumentaron con la edad en los hombres. Además, la probabilidad de sufrir una LAT fue mayor entre los hombres en comparación con la jornada de trabajo estándar, también para los ajustes del Modelo 1 y del Modelo 2.  Conclusiones: Las jornadas laborales prolongadas están asociadas con las LAT en los hombres. En el caso de las mujeres no se observó una asociación estadísticamente significativa. La implementación de medidas preventivas que tomen en cuenta la duración de las jornadas de trabajo en las empresas podría resultar en una reducción de las LAT

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business.
