          Abstract

          Resumen 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 (OR = 3,08; IC95%: 1,87-5,07), también para los ajustes del Modelo 1 (OR = 2,98; IC95%: 1,79-4,95) y del Modelo 2 (OR = 3,05; IC95%: 1,82-5,11). Conclusiones: Las jornadas laborales prolongadas están asociadas con las LAT en los hombres. En el caso de las mujeres, pese a que la frecuencia de LAT fue mayor en las expuestas a jornadas laborales prolongadas respecto a las expuestas a jornadas estándar, 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.

          Abstract 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, divided 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 occupational 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 standard 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 associations were observed. Implementation of preventive measures that consider the length of working hours in companies could result in the reduction of OI.

            The association between long working hours and health: a systematic review of epidemiological evidence.

            Many studies have investigated the association between long working hours and health. By focusing on differences in the definition of long working hours and the influence of shift work, we attempt to explain why the results of these studies remain inconclusive. We defined long working hours as working time greater than around 40 hours per week or 8 hours per day. Since previous studies have indicated that shift work is detrimental to health, we minimized the influence of shift work in the studies. We also placed importance on the existence of reference groups since this made the results clearer. Based on these points, we analyzed previous studies to clarify the epidemiological evidence regarding the association between long working hours and health. We established inclusion criteria and carried out a systematic search for articles published in the Medline and PsycINFO databases between 1995-2012. We identified a total of 17 articles and 19 studies (12 prospective cohort and 7 cross-sectional studies). The outcomes were all-cause mortality, circulatory disease, diabetes mellitus, metabolic syndrome, depressive state, anxiety, other psychological disorders, sleep condition, cognitive function, and health-related behavior. Long working hours had significant adverse effects on most health outcomes. We concluded that working long hours is associated with depressive state, anxiety, sleep condition, and coronary heart disease. However, further studies that appropriately deal with the definition of long working hours and shift work are needed.

              Long workhours and health.

              This paper summarizes the associations between long workhours and health, with special attention for the physiological recovery and behavioral life-style mechanisms that may explain the relationship. The evidence for these mechanisms has not been systematically reviewed earlier. A total of 27 recent empirical studies met the selection criteria. They showed that long workhours are associated with adverse health as measured by several indicators (cardiovascular disease, diabetes, disability retirement, subjectively reported physical health, subjective fatigue). Furthermore, some evidence exists for an association between long workhours and physiological changes (cardiovascular and immunologic parameters) and changes in health-related behavior (reduced sleep hours). Support for the physiological recovery mechanism seems stronger than support for the behavioral life-style mechanism. However, the evidence is inconclusive because many studies did not control for potential confounders. Due to the gaps in the current evidence and the methodological shortcomings of the studies in the review, further research is needed.
