Sick Leave in Colombia in the 2016-2018 period: A Retrospective Cross-Sectional Observational Study / Licencia por enfermedad en Colombia en el período 2016-2018: Estudio observacional transversal retrospectivo

Introduction: To understand the sick leave situation and the causes and effects of a temporary loss of capacity to work allows for the strengthening of policies and management in the provision of health services. Objective: To analyze sick leave in Colombia in the 2016-2018 period. Materials and methods: A retrospective cross-sectional observational study and the relative risk was calculated. Sick leave reports were provided by the Ministry of Health and Social Protection. 12,410,837 reports from formal workers between the ages of 18-70 years and had at least one temporary disability were processed. Results: The average age of people with sick leave was 37.11 years, 53% corresponding to females. On average, sick leave was 90.6% and 5.6% for dependent and independent workers, respectively. The principal causes of disability were musculoskeletal diseases and were more likely in men and adults according to RR. Men in comparison to females and adults in comparison to youths are less likely to have sick leave due to respiratory disease. Conclusions: In Colombia, females presented more temporary sick leave, even if males had more days of disability, even though the median was three days in both genders. Youth and adults had more sick leave days.

Introducción: Comprender la situación de incapacidad por enfermedad, causas y efectos de una pérdida temporal de la capacidad de trabajo fortalece las políticas y la gestión en la prestación de servicios de salud. Objetivo: Analizar las incapacidades por enfermedad en Colombia en el período 2016-2018. Materiales y métodos: Estudio observacional transversal retrospectivo, con cálculo del riesgo relativo. Se procesaron 12.410.837 registros de trabajadores formales entre 18 y 70 años de edad y con al menos una incapacidad temporal, según los informes del Ministerio de Salud y Protección Social. Resultados: La edad promedio de las personas fue de 37,11 años, 53% fueron mujeres. En promedio, el 90,6% de las incapacidades fue para trabajadores dependientes y el 5,6% trabajadores independientes. Las principales causas de incapacidad fueron las enfermedades del sistema musculoesquelético más frecuentes en hombres adultos según RR. Los hombres en comparación con las mujeres y los adultos en comparación con los jóvenes tienen menos probabilidades de tener licencia por enfermedad respiratoria. Conclusiones: Las mujeres presentaron más incapacidades temporales por enfermedad, aunque los hombres tuvieron más días de incapacidad, la mediana fue de tres días en ambos géneros. Los jóvenes y los adultos tenían más días de baja por enfermedad.

Biomarkers of susceptibility and effect in car painters exposed to organic solvents.

INTRODUCTION: Car painters are routinely exposed to organic solvents classified as carcinogenic and mutagenic substances. OBJECTIVE: To characterize the population susceptibility and evaluate the genotoxic effects of exposure to organic solvents. METHODS: A cross-sectional study comparing a group of car painters exposed to organic solvents with a non-exposed group. CYP2E1 polymorphisms and the presence of micronuclei in lymphocytes were determined. RESULTS: One hundred twenty-two workers participated in the study: 62 who worked in car paint shops and were exposed to solvents, and 60 who were not exposed. There were statistically significant differences between the two groups regarding micronucleated cells and nucleoplasmic bridges frequencies (p= 0.042 and p= 0.046, respectively; exact likelihood ratio). Significant differences were found at the interaction between the CYP2E1 genotype c1c1 and occupational exposure to solvents, with higher frequencies of micronuclei (p= 0.013) and micronucleated cells (p= 0.015). However, when the frequencies of micronuclei, micronucleated cells and nucleoplasmic bridges in the exposure group were compared between the c1c1 and c2c2/c1c2 allele groups of the CYP2E1 polymorphism, statistically significant differences were found. CONCLUSIONS: This study confirms that when workers with CYP2E1 polymorphisms, specifically the c1c1 genotype, are exposed to organic solvents, they are more likely to have somatic cell mutations, a condition associated with increased susceptibility to diseases such as cancer.

INTRODUCCIÓN: Los pintores de vehículos automotores están rutinariamente expuestos a agentes como los solventes orgánicos, capaces de producir efectos mutágenos y carcinógenos. OBJETIVO: Caracterizar la susceptibilidad poblacional y evaluar los efectos genotóxicos debidos a la exposición a solventes orgánicos. MÉTODOS: Estudio de corte transversal que comparó a un grupo de pintores de carros expuestos a solventes orgánicos con un grupo de personas no expuestas. Fueron determinados tanto los polimorfismos de CYP2E1 como la presencia de micronúcleos en linfocitos. RESULTADOS: Participaron 122 personas, 62 trabajadores de talleres de pintura de autos expuestos a solventes y 60 personas no expuestas. Con relación al cuestionario Q 16, 32% de los expuestos refirieron síntomas sugestivos de neurotoxicidad. Las frecuencias de células micronucleadas y de puentes nucleoplásmicos fueron significativamente mayores en los expuestos que en los no expuestos: p= 0.042 y p= 0.046, respectivamente, Razón de verosimilitud exacta). Fueron halladas diferencias significativas en la interacción de CYP2E1 (c1c1) y la exposición ocupacional a solventes, con mayores frecuencias de micronúcleos (p= 0.013) y de células micronucleadas (p= 0.015). CONCLUSIONES: Este estudio reafirma que los trabajadores expuestos a solventes orgánicos con polimorfismos de CYP2E1, específicamente con genotipo c1c1, tienen mayor probabilidad de presentar mutaciones en las células somáticas, condición asociada con una mayor susceptibilidad a enfermedades como el cáncer.

Exposure to pesticide mixtures and DNA damage among rice field workers.

This study describes the use of pesticides mixtures and their potential association with comet assay results in 223 rice field workers in Colombia. Thirty-one pesticides were quantified in blood, serum, and urine (15 organochlorines, 10 organophosphorus, 5 carbamates, and ethylenethiourea), and the comet assay was performed. Twenty-four (77.42%) pesticides were present in the workers. The use of the maximum-likelihood factor analysis identified 8 different mixtures. Afterwards, robust regressions were used to explore associations between the factors identified and the comet assay. Two groups of mixtures--α-benzene hexachloride (α-BHC), hexachlorobenzene (HCB), and ß-BHC (ß: 1.21, 95% confidence interval [CI]: 0.33-2.10) and pirimiphos-methyl, malathion, bromophos-methyl, and bromophos-ethyl (ß: 11.97, 95% CI: 2.34-21.60)--were associated with a higher percentage of DNA damage and comet tail length, respectively. The findings suggest that exposure to pesticides varies greatly among rice field workers.

Servicios de medicina del trabajo en Colombia / Occupational medicine services in Colombia

Objetivo: Caracterizar la calidad técnica de los servicios que en el área de medicina del trabajo ofertan las instituciones prestadoras de servicios de salud ocupacional (IPSSO) en las principales ciudades del país. Métodos: Corresponde a un estudio descriptivo de corte transversal (2009-2010) de cobertura nacional (15 ciudades) en el que mediante la aplicación de una encuesta diagnóstica se obtuvo información de 192 Instituciones Prestadoras de Servicios de Salud Ocupacional (IPSSO). Resultados: El estudio evidenció que el 74,7 % de las IPSSO cuentan con licencia vigente para la prestación de servicios en el área de medicina del trabajo, que la oferta de servicios se realiza sobre la base de la subcontratación tanto de profesionales como de equipos y que el uso de las guías de atención integral en salud ocupacional basadas en la evidencia (GATISO), es muy incipiente. Conclusiones: Se identificaron, entre otras, deficiencias técnicas, administrativas, de gestión, de infraestructura y de personal, que afectan la calidad de los servicios de medicina del trabajo ofertados por las IPSSO, las cuales no permiten asegurar que se estén estudiando a profundidad y con suficiencia los efectos de los factores de riesgo en la salud de los trabajadores.

Objective: Characterizing the technical quality of occupational medicine services being provided by occupational health supply providing institutions (OHSPI) in Colombia’s main cities. Materials and Methods: This was a national descriptive cross-sectional study (2009- 2010) in which a diagnostic survey was used for obtaining data regarding 192 OHSPI. Results: The study demonstrated that 76 % of the OHSPI had a license for offering occupational medicine services. Institutions provide services by subcontracting professionals and the necessary equipment. It also revealed infrequent use of integral attention for evidence-based occupational health guidelines (EBOHG). Conclusion: Deficiencies affecting the quality of occupational medicine services were identified. Such deficiencies hampered in-depth studies about the effects of the risk factors on workers’ health, meaning that monitoring and controlling occupational health care services offered by the OHSPI must be reinforced to assure the availability of resources and the execution of disease prevention programs to maintain and improve workers’ state of health.
