[Basic questionnaire and methodological criteria for Surveys on Working Conditions, Employment, and Health in Latin America and the Caribbean]. / Cuestionario básico y criterios metodológicos para las Encuestas sobre Condiciones de Trabajo, Empleo y Salud en América Latina y el Caribe.

This article aimed to present a basic questionnaire and minimum methodological criteria for consideration in future Surveys on Working Conditions, Employment, and Health in Latin America and the Caribbean. A virtual and face-to-face consensus process was conducted with participation by a group of international experts who used the surveys available up until 2013 as the point of departure for defining the proposal. The final questionnaire included 77 questions grouped in six dimensions: socio-demographic characteristics of workers and companies; employment conditions; working conditions; health status; resources and preventive activities; and family characteristics. The minimum methodological criteria feature the interviewee's home as the place for the interview and aspects related to the quality of the fieldwork. These results can help improve the comparability of future surveys in Latin America and the Caribbean, which would in turn help improve information on workers' heath in the region.

[Social class, psychosocial occupational risk factors, and the association with self-rated health and mental health in Chile]. / Clase social, factores de riesgo psicosocial en el trabajo y su asociación con la salud autopercibida y mental en Chile.

The objective of this study was to analyze the association between social class and psychosocial occupational risk factors and self-rated health and mental health in a Chilean population. A cross-sectional study analyzed data from the First National Survey on Employment, Work, Quality of Life, and Male and Female Workers in Chile (N = 9,503). The dependent variables were self-rated health status and mental health. The independent variables were social class (neo-Marxist), psychosocial occupational risk factors, and material deprivation. Descriptive and logistic regression analyses were performed. There were inequalities in the distribution of psychosocial occupational risk factors by social class and sex. Furthermore, social class and psychosocial occupational risk factors were associated with unequal distribution of self-rated health and mental health among the working population in Chile. Occupational health interventions should consider workers' exposure to socioeconomic and psychosocial risk factors.

El objetivo fue examinar la relación entre clase social, riesgo psicosocial laboral y la salud autopercibida y mental en Chile. Se trata de un estudio transversal con los datos de la Primera Encuesta Nacional de Condiciones de Empleo, Trabajo, Calidad de Vida y Salud de los Trabajadores y Trabajadoras en Chile (N = 9.503). Las variables dependientes son: salud mental y salud autopercibida. Las variables explicativas son: clase social neo-marxista, factores de riesgo psicosocial y privación material. Se realizaron análisis descriptivos y de regresión logística. Existen desigualdades en la distribución de los factores exposición laboral a riesgos psicosociales, según clase social y sexo. Además, la clase social y los factores de riesgo psicosocial en el trabajo están asociados a una distribución desigual de la salud autopercibida y salud mental entre la población trabajadora en Chile. Las intervenciones en el área de la salud de los trabajadores deben considerar la clase social y los factores de riesgo psicosocial a que están expuestos los trabajadores.

Além disso, a classe social e os fatores de risco psicossociais no trabalho estão associados a uma distribuição desigual da saúde autopercebida e saúde mental. As intervenções na área da saúde dos trabalhadores devem considerar a classe social e fatores de risco psicossociais a que os trabalhadores estão expostos.

Factores asociados a accidentes, enfermedades y ausentismo laboral: análisis de una cohorte de trabajadores formales en Chile / Factors associated with accidents, illness and absenteeism: analysis of a cohort of formal workers in Chile

Objetivo: Estimar la asociación entre factores de riesgo y la ocurrencia de enfermedades, accidentes y ausentismo laboral en trabajadores formales. Método: Estudio de cohorte retrospectiva usando dos fuentes de información: registro de evaluaciones ocupacionales preventivas y de episodios de accidentes y enfermedades laborales (2009-2012). Se realizó un análisis descriptivo de variables de salud y de factores de riesgo. Regresiones logísticas para la ocurrencia de enfermedades y accidentes. Se usó una regresión Poisson-cero-inflado para el ausentismo laboral. Resultados: los > 60 años tienen un exceso de riesgo de enfermedad laboral (OR-ajustada 19,18 respecto a < 30 años) y los sedentarios una OR-ajustada 1,75. Los < 30 años tienen una OR-ajustada de 1,38, los que tienen circunferencia de cintura (CC) superior a la recomendada una OR-ajustada de 1,31 y los sedentarios 1,23 para la probabilidad de accidentes de trabajo. Las mujeres tienen una OR-ajustada 1,99 y CC-superior 1,29 para la probabilidad de accidente de trayecto. Ser mujer (IRR 1,45), tener > 60 años (IRR 2,69), trabajar en actividades inmobiliarias (IRR 2,37) y en explotación de minas (IRR 2,38), tienen una probabilidad mayor de más días de ausentismo. Conclusiones: Factores no modificables (sexo y edad), junto con factores modificables, como el sedentarismo y el estado nutricional, contribuyen a eventos laborales no deseados.

Objective: To determine the association among lifestyle-related risk factors and the occurrence of occupational diseases, accidents and absenteeism in a cohort of formal workers. Method: A retrospective cohort study was carried out by using two information sources: a registry of preventive occupational evaluations and another registry of episodes of occupational accidents and diseases (2009-2012). A descriptive analysis was performed of health variables and risk factors. Logistic regressions were used to calculate the likelihood of occupational accidents and diseases and a zero-inflated Poisson regression was used to model occupational absenteeism. Results: A total of 47.221 workers were included, of which 86,3% were men. The mean follow-up was 1,96 years. Workers aged >60 years had an excess risk of occupational diseases, with an OR of 19.18 compared with workers aged <30 years, while sedentary workers had an OR of 1,75. The likelihood of occupational accidents was higher in workers younger than 30 years (OR 1,38), those with a waist circumference (WC) higher than recommended (OR 1,31) and those who were sedentary (OR 1,23). Women had an OR of 1.99 and those with a WC higher than recommended had an OR of 1,29 for the likelihood of a commuting accident to and from work. Female sex (IRR 1,45), age >60 years (IRR 2,69), and working in the property sector (IRR 2,37) and in mining (IRR 2,38) conferred a higher probability of absenteeism. Conclusions: Unmodifiable factors (age and sex), as well as modifiable factors, such as sedentariness and nutritional status, contribute to undesired occupational events.

[Social class, health inequalities, and health-related behaviors of working people in Chile]. / Clase social, desigualdades en saludy conductas relacionadas con la saludde la población trabajadora en Chile.

OBJECTIVE: To analyze links between social class and health-related indicators and behaviors in Chilean workers, from a neo-Marxian perspective. METHODS: A cross-sectional study based on the First National Survey on Employment, Work, Health, and Quality of Life of Workers in Chile, done in 2009-2010 (n = 9 503). Dependent variables were self-perceived health status and mental health, examined using the General Health Questionnaire (GHQ-12). Health-related behavior variables included tobacco use and physical activity. The independent variable was neo-Marxian social class. Descriptive analyses of prevalence were performed and odds ratio (OR) models and 95% confidence intervals (95%CI) were estimated. RESULTS: Medium employers (between 2 and 10 employees) reported a lower prevalence of poor health (21.6% [OR 0.68; 95%CI 0.46-0.99]). Unskilled managers had the lowest mental health risk (OR 0.43; 95%CI 0.21-0.88), with differences between men and women. Large employers (more than 10 employees) reported smoking the least, while large employers, expert supervisors, and semi-skilled workers engaged in significantly more physical activity. CONCLUSIONS: Large employers and expert managers have the best health-related indicators and behaviors. Formal proletarians, informal proletarians, and unskilled supervisors, however, have the worst general health indicators, confirming that social class is a key determinant in the generation of population health inequalities.

Clase social, desigualdades en salud y conductas relacionadas con la salud de la población trabajadora en Chile / Social class, health inequalities, and health-related behaviors of working people in Chile

OBJETIVO: Analizar los vínculos entre la clase social y los diferentes indicadores y conductas relacionados con la salud, a partir de una perspectiva neomarxista en población trabajadora chilena. MÉTODOS: Se realizó un estudio transversal a partir de la Primera Encuesta Nacional de Condiciones de Empleo, Trabajo, Salud y Calidad de Vida de los Trabajadores y Trabajadoras en Chile, efectuada en 2009-2010 (n = 9 503). Las variables dependientes fueron el estado de salud autopercibido y la salud mental, examinada mediante el Cuestionario de Salud Global (GHQ-12, por sus siglas en inglés). Las variables de conductas relacionadas con la salud incluyeron el consumo de tabaco y la realización de actividad física. La variable independiente fue la clase social neomarxista. Se realizaron análisis descriptivos de prevalencia y se estimaron modelos de razón de probabilidades (RP) e intervalos de confianza de 95% (IC95%). RESULTADOS: Los medianos empresarios refirieron tener una menor prevalencia de mala salud (21,6% [RP 0,68; IC95% 0,46-0,99]). En relación a la salud mental, los que presentaban menor riesgo eran los gerentes básicos (RP 0,43; IC95% 0,21-0,88), observándose diferencias entre hombres y mujeres. Los que refirieron fumar con menor frecuencia fueron los empresarios, mientras que los que realizaban significativamente más actividad física fueron los empresarios, los supervisores expertos y los trabajadores semicalificados. CONCLUSIONES: Los empresarios y gerentes expertos son los que presentan mejores indicadores y conductas relacionados con la salud. El proletario formal, el proletario informal y los supervisores básicos, en cambio, son los que presentan los peores indicadores de salud global, confirmando así que la clase social es un determinante clave en la generación de desigualdades en materia de salud de la población.

[Social class and health in Latin America]. / Clase social y salud en América Latina.

This paper reviews the principal concepts of social class, occupation, and social stratification, and their contribution to the analysis of the social determinants of health (SDH), and reviews empirical studies conducted in Latin America that use employment relations as an SDH. The review focuses on studies of the relationship between health and social class based on neo-Weberian or neo-Marxist perspectives. A search of the BIREME Virtual Health Library and the SciELO database found 28 articles meeting these characteristics. This relative dearth contrasts with the profusion of papers that use these approaches written in Europe and in the United States, with a long tradition in the analysis of SDH. In this regard, the political and programmatic implications of research on social class and employment relations are different from and complementary to studies of health gradients associated with income and education. Globalization of employment relations requires the development of new concepts to explain and measure the mechanisms of action of the SDH going beyond what is strictly labor related; in particular, the importance in the current Latin American reality of the impact of informal work on health.

Clase social y salud en América Latina / Social class and health in Latin America

Se repasan los principales conceptos de clase social, ocupación y estratificación social, y su contribución al análisis de los determinantes sociales de la salud (DSS), y se revisan los estudios empíricos desarrollados en América Latina que utilicen las relaciones de empleo como DSS. La revisión se ha enfocado en los estudios sobre la relación entre salud y clase social basados en las perspectivas neoweberiana o neomarxista. La búsqueda en la Biblioteca Virtual en Salud de BIREME y en la base de datos SciELO permitió localizar 28 artículos de esas características. Esta relativa escasez contrasta con la abundancia de trabajos con tales enfoques realizados en Europa y en los Estados Unidos, con una larga tradición en el análisis de los DSS. En tal sentido, las implicaciones políticas y programáticas de la investigación sobre clase social y relaciones de empleo son diferentes y complementarias de los estudios de gradientes de salud asociados a los ingresos y la educación. La globalización en las relaciones de empleo exige nuevos conceptos para explicar y medir los mecanismos de acción de los DSS trascendiendo lo estrictamente laboral; en particular, la relevancia en la realidad latinoamericana actual del impacto del trabajo informal sobre la salud.

Enfermedades no transmisibles: emergencia de salud pública en cámara lenta: un desafío para Chile / Non communicable diseases: a slow speed emergency: a challenge for Chile

Las enfermedades no transmisibles (ENTs), cardiovasculares, cáncer, diabetes y enfermedades respiratorias crónicas son la principal causa de muerte en Chile y en el mundo. Cuatro factores de riesgo conductuales: tabaquismo, dieta no saludable, actividad física insuficiente y el consumo perjudicial de alcohol, asociados a la transición económica, la urbanización acelerada y el estilo de vida del siglo XXI, son en gran parte la causa de estas enfermedades, las que emergen como un desafío macroeconómico para el desarrollo. La pandemia de ENTs tiene su origen en la pobreza y afecta en forma desproporcionada a los más desposeídos. Las intervenciones que han demostrado ser más efectivas para reducir las ENTs son aquellas dirigidas a prevenir los factores de riesgo señalados a nivel poblacional. Aunque Chile ha suscrito las principales iniciativas propuestas por la OMS para combatir los factores de riesgo señalados, su implementación es aún incompleta. El país ha avanzado en muchos aspectos, pero tiene importantes desafíos en términos de la vigilancia de las ENTs, el fortalecimiento de la APS, incluyendo los recursos humanos y financiamiento, y la incorporación de tecnologías. Abordar los factores de riesgo y los determinantes sociales de la salud excede la capacidad del sector salud y requiere una respuesta multisectorial con la participación del sector público, privado, la sociedad civil y la colaboración internacional. La reunión de alto nivel en Naciones Unidas en septiembre 2011, sobre Prevención y Control de las Enfermedades no Transmisibles señala el inicio de un proceso para abordar las ENTs para el cual se requiere el liderazgo del Estado de Chile para prevenir o mitigar el impacto de estas enfermedades en las personas, particularmente en aquellas más vulnerables.

Non communicable diseases (NCDs) are the main cause of death worldwide and in Chile. Behavioural risk factors – tobacco, an unhealthy diet, insufficient physical exercise, and alcohol abuse, together with the economic transition, swift urbanization and the 21st century lifestyles are the main cause of these conditions, which in turn are a macroeconomic challenge to development. The NCDs pandemic is rooted in poverty and particularly affects the poor. The interventions that have proved to be most effective in reducing the NCDs are those aimed at the prevention, at population level, of the above mentioned factors. Although Chile has accepted the main initiatives proposed by WHO in order to fight those factors, their implementation is still not complete. Progress has been achieved in some aspects, but important challenges remain in the areas of epidemiological surveillance of NCDs, and of PHC strengthening particularly in regard to human, financial and technological resources. The task of addressing the risk factors and the social determinants of health excedes the capability of the health care sector and requires a multisectorial response, with the participation of the public and private sectors, civil society and international collaboration. The UN high level Meeting on Prevention and Control of NCDs, in September 2011, marks the beginning of a process for which the leadership of the Chilean Government is required in order to prevent or mitigate the impact of these diseases on individuals, and particulrly on the most vulnerable ones.

[Review and guidelines for treatment of diarrhea caused by Vibrio parahaemolyticus]. / Revisión y recomendaciones para el manejo de diarrea por Vibrio parahaemolyticus.

In Chile Vibrio parahaemolyticus has been detected in 3 gastroenteritis outbreaks since 1998. The most recent outbreak occurred during the summer of 2005, affecting over 10,000 people of whom one died. Affected individuals presented with one or more of the following symptoms: diarrhea, nausea, vomiting, abdominal pain and/or fever. Fecal white blood cells were detected in only 6% of patients. The predominant serotype in the 3 outbreaks was the pandemic O3:K6 strain. Diagnosis was confirmed by isolation and identification of V. parahaemolyticus in stool cultures and/or by establishing an epidemiological link. V. parahaemolyticus isolates were 100% susceptible to tetracycline, ciprofloxacin and chloramphenicol, and universally resistant to ampicillin. Due to the public health impact of the 2005 outbreak, the Ministry of Health called for a National Task Force mandated to review epidemiological, clinical and microbiological features of the outbreak and to propose management guidelines.
