Mapping the conceptual structure of ergonomics, musculoskeletal disorders, treatment and return to work in manual jobs: A systematic review.

BACKGROUND: Musculoskeletal disorders constitute one of the major health problems of workers exposed to manual work throughout the world. Nevertheless, there is no study that maps its conceptual structure based on a systematic methodology. OBJECTIVE: To identify the conceptual structure of ergonomics, MSDs, treatment and return to work in manual jobs in the last 12 years by applying a systematic co-word network analysis methodology which describes the replicability of the search filters and emphasizes the rigor that has to be followed in the creation of the network. METHODS: The search filter was customized for each bibliographic database, and followed the PRISMA 2020 flowchart for the screening process. For the creation of the network, the titles, abstracts, and keywords were used as the unit of analysis extracting the noun phrases of the first two units. In the normalization process, the terms of the search filter were deleted and their associated terms, and standardized the similar terms. Regarding the plotting of the network, Vosviewer was used applying the network settings based on content analysis. RESULTS: The co-word network shows three communities: Ergonomic assessment and workplace intervention tools, factors related to rehabilitation and return to work, and physical and mental overload management. For each community, there is a framework that explains the relationship within terms. CONCLUSION: This study is aligned with the replicability, robustness, and relevance recommendations in the implementation of rigorous scientometric studies. The occupational health community is encouraged to implement scientometric studies following a rigorous methodology and working in interdisciplinary team.

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 / Long working hours and occupational injuries: estimates from the First Survey on Safety and Health Conditions at Work in 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 (AU)

Objective: to estimate the association between weekly working hours and occupational injuries (OI) among the salaried population in Guayaquil, Ecuador. Methods: a cross-sectional study that used data from the First Survey on Safety and Health Conditions at Work in Ecuador in 2017. The respondents were 1005 salaried workers, divid-ed into two groups according to weekly working hours, ≤43 and ≥44 hours. The relationship between long working hours and OI by gender was analyzed by using logistic regression (OR; CI 95%) adjusted for sociodemographic characteristics (Model 1) and also for occupa-tional characteristics (Model 2). Results: 30.9% of the workers declared ≥44 weekly working hours (50.7±6.3 hours) and the OI percentages in this group were higher in men (24.2%) compared to women (12%). OI among those working long hours increased with age in men. In addition, the odds of sustaining an OI were higher among men working long hours as compared to the stan-dard working day (OR = 3.08; 95% CI: 1.87–5.07), for Model 1 settings (OR = 2, 98; 95% CI: 1.79–4.95) and Model 2 (OR = 3.05; 95% CI: 1.82–5.11). Conclusions: Long working hours are associated with OI in men. In the case of women, despite the fact that the frequency of OI was higher in those exposed to long working hours compared to those exposed to standard working hours, no statistically significant associ-ations were observed. Implementation of preventive measures that consider the length of working hours in companies could result in the reduction of OI. (AU)

Letalidad por desplazamientos domicilio-trabajo-domicilio en el Ecuador, 2014-2019 y 2020 / Home-workplace-home commuting lethality in Ecuador, 2014-2019 and 2020

Objetivo: Evidenciar las diferencias de letalidad según lugar de ocurrencia (desplazamientos = in itínere y en jornada laboral) en el periodo entre 2014 a 2019 y 2020 en el Ecuador. Material y Métodos: Análisis de 104.396 casos (1,2% mortales) utilizando registros oficiales. Se estimaron Tasas de Letalidad (TL) y Razón de Tasas de Letalidad (RTL) por lugar de ocurrencia y separadas por sexo. Resultados: Las TL y RTL mostraron descensos importantes. Sin embargo, las probabilidades de fallecimiento in itínere fueron mayores en comparación a los accidentes mortales ocurridos en jornada laboral, de forma global [1,51 (IC95% = 1,13-2,04); p = 0,006], en hombres, [1,58 (IC95% = 1,38-1,82); p = 0,000] y, en específico, en mujeres, [5,93 (IC95% = 1,86-16,34); p = 0,001]. Conclusiones: Se deberían realizar estudios epidemiológicos específicos y prestar mayor interés a este problema de seguridad vial laboral en el diseño de estrategias de salud pública y laboral. (AU)

Objective: To demonstrate the differences in fatality rates by place of occurrence (commuting = in itínere and during working hours) in the period from 2014 to 2019 and 2020 in Ecuador. Material and Methods: Analysis of 104,396 cases (1.2% fatal) using official records. Lethality Rates (LR) and Lethality Rate Ratio (LRR) were estimated by place of occurrence and separated by sex. Results: LR and LRR showed significant decreases. However, the odds of in itínere fatalities were higher in comparison to work-related fatalities, overall [1.51 (95%CI = 1.13-2.04); p = 0.006], in men, [1.58 (95%CI = 1.38-1.82); p = 0.000] and specifically in women, [5.93 (95%CI = 1.86-16.34); p = 0.001]. Conclusions: Specific epidemiological studies should be carried out and more interest should be given to this occupational road safety problem in the design of public and occupational health strategies.

Comportamiento de lesiones por accidente de trabajo no mortales y con incapacidad temporal, en personas afiliadas al régimen general de seguridad social en Ecuador. Análisis temporal y territorial en ocupaciones manuales de las industrias manufacturera y de construcción, 2014-2019 / Behavior of non-fatal occupational injuries with temporary disability among members of Ecuador's general social security system. Temporal and territorial analysis in manual occupations in the manufacturing and construction industry, 2014 - 2019 / Comportamento de lesões profissionais não fatais e temporariamente incapacitadas em pessoas filiadas ao sistema geral de segurança social no Equador. Análise temporal e territorial em ocupações manuais das indústrias manufatureiras e de construção, 2014-2019

El análisis de datos cuantitativos de siniestralidad laboral es importante para orientar la gestión preventiva en la República del Ecuador. Se presenta un estudio ecológico exploratorio de la incidencia de lesiones por accidente de trabajo no mortales y con incapacidad temporal, en ocupaciones manuales de las industrias manufacturera y de construcción en 23 provincias del país, para el período comprendido entre 2014 y 2019. Como fuente se utilizaron los registros oficiales de trabajadoras y trabajadores afiliados al régimen general de seguridad social. Se apli- có el programa estadístico SPSS versión 21.0 y Tableau versión 3.0; se agruparon las provincias del Ecuador en cuartiles según el valor de la tasa de incidencia de las lesiones por cada 1.000 personas afiliadas, considerando año y actividad económica. Las tasas de incidencia mues- tran patrones similares para los dos sectores económicos y un decrecimiento progresivo en el período analizado, con valores semejantes en 2019. Los valores más altos se presentan en las provincias de Azuay, Guayas, Pichincha y Tungurahua. Se concluye que existen importantes di- ferencias geográficas, lo que demanda estrategias de prevención y disminución de accidentes de trabajo con participación de los equipos interdisciplinarios relacionados, incluyendo terapeutas ocupacionales.

Analyzing quantitative data on occupational accidents is essential to guide preventive management in the Republic of Ecuador. An exploratory ecological study of the incidence of non-fatal and temporary incapacity occupational injuries in manual occupations in the manufacturing and construction industries in 23 provinces is presented for the period 2014-2019. Official registers of workers registered in the general social security system were used as a source. The statistical software SPSS version 21.0 and Tableau version 3.0 were applied; Ecuador provinces were grouped into quartiles according to the value of the incidence rate of injuries per 1,000 registered persons, considering the year and economic activity. Incidence rates show similar patterns for the two economic sectors and a progres- sive decrease over the period analyzed, with similar values in 2019. The highest values are found in Azuay, Guayas, Pichincha and Tungurahua provinces. It is concluded that there are significant geographical differences, which calls for strategies to prevent and reduce occupational accidents with the participation of related interdisciplinary teams, including occupational therapists.

Conclui-se que existem diferenças geográficas importantes, que demandam estratégias de prevenção e de redução dos aciden- tes de trabalho com a participação de equipes interdisciplinares relacionadas, incluindo terapeutas ocupacionais.

[Safety and Health at Work in Ecuador]. / Seguridad y salud en el trabajo en Ecuador.

La República del Ecuador (en adelante Ecuador) puede ser considerada como uno de los países latinoamericanos más privilegiados por sus contrastes geográficos, variedad climática y amplia biodiversidad. La Cordillera de los Andes divide al Ecuador en tres regiones (Amazonía, Sierra y Costa del Pacífico) con marcadas diferencias culturales. Además, existen el conjunto de las Islas Galápagos como cuarta región. La población (2020) es de 17,5 millones de habitantes (51% son mujeres) y la esperanza de vida aumentará significativamente en los próximos años (2010 fue de 75 años y para el 2030 será de 80,5 años). En contraste, los indicadores de salud, económicos y laborales muestran un paronarma preocupante. La tasa de mortalidad en los últimos años ha aumentado ligeramente, en 2014 fue de 4,1 por cada 1000 habitantes y en 2019 fue de 4,3 por cada 1000 habitantes. En 2019, la primera causa de muerte fueron las enfermedades isquémicas del corazón, tanto en mujeres y hombres, y en adultos de 30 a 64 años los accidentes de transporte. Aunque la economía de Ecuador ha mostrado un crecimiento hasta mediados de la última década, la caída del precio internacional del petróleo provocó una recesión económica, con pérdidas de plazas de empleo adecuado desde 2015 y que se mantienen progresivamente en la actualidad. El empleo informal ha crecido rápidamente, situándose en el 46,7% en 2019, y en condiciones precarias de trabajo y ausencia derechos de protección social. Desafortunadamente, la crisis sanitaria por el SARS-CoV-2 ha provocado aún más un entorno desfavorable y retroceso en los objetivos marcados para reducir las desigualdades sociales….

Association between informal employment and mortality rate by welfare regime in Latin America and the Caribbean: an ecological study.

OBJECTIVE: We aimed to estimate the association between informal employment and mortality in Latin America and the Caribbean (LAC) by comparing welfare state regimes. DESIGN: Ecological study using time-series cross-sectional analysis of countries. Informality was estimated from household surveys by the Center for Distributive, Labor and Social Studies in collaboration with the World Bank, and the adult mortality rates for 2000-2016 were obtained from the WHO databases. Countries were grouped by welfare state regimes: state productivist, state protectionist and familialist. We calculated the compound annual growth rate for each country and performed linear regression between the informality and the adult mortality rates stratified by sex and welfare state regime. SETTING: Seventeen countries from LAC with available data on informality and adult mortality rates for 2000-2016. PRIMARY OUTCOME MEASURE: The association between informality and mortality by welfare state regime. RESULTS: Between 2000 and 2016, mortality rates decreased an average 1.3% per year and informal employment rates 0.5% per year. We found a significant positive association between informality and mortality rates (women: R2=0.48; men: R2=0.36). The association was stronger among the state regime countries (women: R2=0.58; men: R2=0.77), with no significant association among the familialist countries. CONCLUSION: Informal employment negatively impacts population health, which is modified by welfare state regimes. Addressing informal employment could be an effective way to improve population health in LAC. However, linkage with public health and labour market agendas will be necessary.

Understanding the Relationship between Situational Strength and Burnout: A Multi-Sample Analysis.

Many studies have examined the effect of situational strength (clarity, consistency, constraints, and consequences) on organisational behaviour, but little has been investigated about its health effects. This study aimed to analyse the relationship between situational strength and burnout. Specifically, we examined whether situational strength characteristics may be associated with burnout, whether these characteristics are risk (or protective) factors for burnout, and whether a strong situation is related to higher levels of burnout. Examining three samples from different occupations, it was found that clarity and consistency are negatively associated with burnout, being protective factors, while constraints are positively associated with burnout, being risk factors. These results are consistent across the samples. In addition to the direct effects, interaction effects between clarity and consistency in the office employee's sample (two-way interaction), between constraints and consequences in the samples of office employees and teachers (two-way interaction), and among clarity, consistency, and constraints in the salespeople's sample (three-way interaction) were also significant, explaining from 20% to 33% of the variance of burnout. We concluded that situational strength is associated not only with behaviour but also with health. The theoretical and practical implications of these findings are discussed.

Salaried Workers' Self-Perceived Health and Psychosocial Risk in Guayaquil, Ecuador.

Self-perceived health is an important indicator of occupational health. This research explored the relationship between poor self-perceived health and exposure to psychosocial risk factors, taking into account potential socio-demographic, occupational, and employment determinants. Using data from the First Survey of Occupational Safety and Health Conditions, covering 1049 salaried workers in Guayaquil, Ecuador, descriptive and stratified binary logistic regression analyses (odds ratios with corresponding 95% confidence intervals) were carried out. A significant relationship was found between exposure to psychosocial risk factors and the probability of presenting poor self-perceived health by socio-demographic, occupational, and employment characteristics. Occupational exposure factors to psychosocial risks were predictors of self-perceived ill health and were related to the variables analyzed; the most frequently expressed factors among the respondents were cognitive demands (DCOG) and job insecurity (IL). The results have implications in terms of designing effective workplace interventions pursuant to ensuring the health and well-being of employees.

Health inequity in workers of Latin America and the Caribbean.

BACKGROUND: 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. METHODS: A sample of 180,163 workers aged 18 years and older was drawn from the most recent national surveys of working conditions or health in 15 LAC countries. Poor self-perceived health (P-SPH) was used as a health indicator, and age, education level, and occupational category as inequality stratifiers. We calculated four measures: absolute and relative population-attributable risks, the Kuznets and weighted Keppel indexes. RESULTS: P-SPH prevalence ranged from 9% in men from Uruguay to 50% in women from Nicaragua. It was higher in women than in men in most countries. A clear gradient was shown, in which young people in non-manual skilled jobs and high education had the lowest prevalence. Nearly 45% of cases that reported P-SPH among men and 35% among women could be avoided if all the groups received a higher level of education. Also, approximately 42% of P-SPH reported by men and 31% by women could be avoided if they all shared the working and employment conditions of non-manual skilled jobs. CONCLUSIONS: Wide health inequalities were found between occupational and educational groups in LAC. However, country borders appear to be an even more important stratifier in the production of health inequalities. Urgent interventions to improve worker's health are needed in countries where prevalence of poor self-perceived health is high. Strengthening occupational health surveillance system in LAC countries should become a priority, in order to track the interventions to reduce occupational health inequity.

Saúde do trabalhador no Equador: uma comparação com inquéritos sobre condições de trabalho na América Latina / Occupational health in Ecuador: a comparison with Latin-American surveys on working conditions / La salud ocupacional en Ecuador: una comparación con las encuestas sobre condiciones de trabajo en América Latina

Resumo Introdução: o Equador realizou recentemente seu primeiro inquérito sobre condições de trabalho. Objetivo: descrever as condições de trabalho e emprego e o estado de saúde dos trabalhadores equatorianos em uma amostra que permita comparação com inquéritos latino-americanos anteriores. Métodos: uma amostra de 1.713 trabalhadores foi selecionada do primeiro inquérito sobre condições de trabalho no Equador. Prevalências e intervalos de confiança de 95% (IC95%) foram calculados e comparados com inquéritos anteriores na Colômbia, Argentina, Chile, América Central e Uruguai. Resultados: homens foram frequentemente mais expostos a trabalho em condições perigosas, sendo as mais relatadas trabalho com ruído (81% dos homens e 69% das mulheres) e com movimentos repetitivos (56% dos homens e 48% das mulheres). Cerca de 31% dos homens e 19% das mulheres trabalhavam mais de 40 horas por semana. Quase 11% das mulheres e dos homens relataram uma autopercepção de saúde ruim. A prevalência de agravos ocupacionais foi a mais alta da região: 15% para homens e 8,4% para mulheres. Conclusão: este é um primeiro levantamento das condições de trabalho e emprego e do estado de saúde de trabalhadores no Equador. Harmonizar e aperfeiçoar os Inquéritos sobre Condições de Trabalho na América Latina deve ser uma meta prioritária para melhorar a vigilância em saúde do trabalhador na região.

Abstract Introduction: Ecuador has recently implemented its First Working Conditions Survey. Objective: to describe working and employment conditions and workers' health status in Ecuador in a sample that allows comparison with previous Latin American surveys. Methods: a sample of 1,713 workers was drawn from the First Working Conditions Survey in Ecuador. Prevalence and a 95% confidence Interval (95%CI) were calculated and compared with previous Latin American surveys in Colombia, Argentina, Chile, Central America, and Uruguay. Results: men were more often exposed to hazardous working conditions, with noise (81% of men and 69% of women), and repetitive movements (56% and 48%, respectively) being the most frequently reported. About 31% of men and 19% of women worked more than 40 hours per week. Almost 11% of both women and men reported poor self-perceived health status. The prevalence of occupational injury was the highest in the region: 15% for men and 8.4% for women. Conclusions: this is a first approach to the working and employment conditions and workers' health status in Ecuador. To harmonize and improve Working Conditions Surveys in Latin America should be a priority goal for enhancing regional occupational health surveillance.

Resumen Introducción: Ecuador ha realizado recientemente su primera encuesta sobre las condiciones de trabajo. Objetivo: describir las condiciones de trabajo y empleo y el estado de salud de los trabajadores en Ecuador en una muestra que permita la comparación con encuestas anteriores en América Latina. Métodos: se seleccionó una muestra de 1.713 trabajadores de la Primera Encuesta de Condiciones de Trabajo en el Ecuador. Se calculó la prevalencia y el intervalo de confianza del 95% (IC95%) y se comparó con las encuestas anteriores realizadas en América Latina - Colombia, Argentina, Chile, América Central y Uruguay. Resultados: hombres se exponen con mayor frecuencia a condiciones de trabajo peligrosas, siendo las más frecuentes el ruido (81% de los hombres y 69% de las mujeres) y los movimientos repetitivos (56% y 48%, respectivamente). Alrededor del 31% de los hombres y el 19% de las mujeres trabajan más de 40 horas por semana. Casi el 11% de las mujeres y de los hombres reportaron mala salud autopercibida. La prevalencia de lesiones ocupacionales fue la más alta de la región: el 15% para los hombres y el 8,4% para las mujeres. Conclusiones: este es un primer acercamiento a las condiciones de trabajo y empleo y al estado de salud de los trabajadores en el Ecuador. Armonizar y mejorar las Encuestas de Condiciones de Trabajo en América Latina debería ser un objetivo prioritario para mejorar la vigilancia de la salud ocupacional en esta región.

Accidentes de tránsito relacionados con el trabajo: una prioridad en salud laboral y pública para Ecuador / Work-related traffic accidents: a priority for occupational and public health in Ecuador

Introducción: En Ecuador, los accidentes de tránsito relacionados con el trabajo han experimentado un incremento en los últimos años y han sido poco estudiados en seguridad y salud en el trabajo. Objetivo: Estimar el riesgo relativo de sufrir accidentes in-itínere en comparación con los accidentes ocurridos en el lugar de trabajo mediante el análisis de fuentes oficiales de información secundaria en el período de 2014 a 2016. Material y métodos: Estudio descriptivo de los accidentes de trabajo relacionados con el trabajo recopilados a través de fuentes oficiales de información secundaria. Para el análisis se utilizaron estadísticos descriptivos, cálculo del riesgo relativo (R.R.-IC95%) y la prueba chicuadrado de Pearson. Resultados: Las mujeres presentan mayor prevalencia y riesgo (R.R. = 1,86; IC95%: 1,80-1,92) de sufrir accidentes in-itínere. Asimismo, los trabajadores del sector industrial y servicios con edades entre los 18 a 35 años (R.R. = 1,16; IC95%: 1,12-1,20) muestran mayor probabilidad que el resto de actividades económicas y grupos etarios. Se observa una tendencia al aumento y probabilidad de fallecer por accidentes in-itínere (R.R. = 1,66; IC95%: 1,43-1,92) que en lugar de trabajo. Conclusiones: Los resultados del presente estudio conllevan a plantearse esta problemática como prioritaria en salud laboral y pública debido al incremento de este tipo de accidentes de trabajo. Surge la necesidad de continuar con futuras investigaciones y atención a este tipo de riesgos laborales por parte de los organismos públicos y empresas del Ecuador(AU)

Background: In Ecuador, work-related traffic accidents have experienced an increase in recent years, but are understudied from the perspective of occupational safety and health. Objective: To estimate the relative risk of suffering accidents initínere compared to workplace accidents by analyzing official sources of secondary information in Ecuador for the period from 2014 to 2016. Material and methods: Descriptive study of work-related accidents collected through official secondary information sources. For the analysis, descriptive statistics, relative risk calculation (R.R. and 95% confidence intervals, -95%CI) and the Pearson chi-square test were used. Results: Women presented a higher prevalence and risk (R.R. = 1.86, 95%CI: 1.80-1.92) of suffering traffic-related accidents. Likewise, industrial sector workers in the 18 to 35 year age group (R.R. = 1.16, 95%CI: 1.12-1.20) are at greater risk oftraffic-related accidents than other economic activity sectors and age groups. There is a trend toward an increased likelihood of dying from a traffic-related accident (R.R. = 1.66, 95%CI: 1.43-1.92) than from an accident at the workplace. Conclusions: Our results identify traffic-related occupational accidents as a priority in occupational and public health. There is a need for more research and increased awareness of these accidents on the part of public authorities and employers in Ecuador(AU)

MATERIALES Y MÉTODOS: Estudio descriptivo a partir de fuentes secundarias reportadas al Seguro General de Riesgos de Trabajo del Instituto Ecuatoriano de Seguridad Social; se emplean frecuencias absolutas (n) y relativas (%), así como el cálculo de la tasa de incidencia en relación con las variables de interés. RESULTADOS: Se evidencia un incremento considerable del número de casos notificados por accidentes de trabajo y posibles enfermedades profesionales; la tasa de incidencia por accidentes aumentó de 381,2 en 2010 a 775,0 en 2015; asimismo, para los casos de enfermedades de 6,0 en 2010 a 28,4 en 2015. CONCLUSIONES: El aumento de registros de accidentes de trabajo y posibles enfermedades profesionales al Seguro General de Riesgos de Trabajo podría deberse a la entrada en vigor de normativas sobre la obligatoriedad de notificación en 2010 y 2011. No obstante, se evidencia la falta de implantación de medidas preventivas en los centros de trabajo, lo que supone plantearse una nueva reformulación de las políticas nacionales en seguridad y salud en el trabajo.

RESULTS: There is a considerable increase in the number of cases reported due to occupational accidents and possible occupational diseases; The incidence rate for accidents increased from 381.2 in 2010 to 775.0 in 2015; Likewise, for cases of diseases from 6.0 in 2010 to 28.4 in 2015. CONCLUSIONS: The increase of records of occupational accidents and possible occupational diseases to the General Insurance of Occupational Risks could be due to the regulations on the obligation of notification that became effective in 2010 and 2011.
