[Metabolic syndrome and other factors cardiovascular risk in workers of a plant of vinyl polychloride]. / Síndrome Metabólico y otros Factores de Riesgo Cardiovascular en Trabajadores de una Planta de Policloruro de Vinilo.

OBJECTIVE: To establish the prevalence of Metabolic Syndrome and other factors of cardiovascular risk in a population of masculine workers of the operative area of the plant of vinyl poly chloride of a petrochemical complex, in the occident of Venezuela. METHOD: An analytical cross sectional study was performed in 84 workers, they was determined size, weight, arterial pressure, abdominal circumference, body mass index, smoke, alcoholic habits and medicaments consumption. Additionally, 10 ml fasting venous blood sample was taken to determine glycemia, total cholesterol, HDL-C, LDL-C and VLDL-C. The diagnosis of the metabolic syndrome was carried out under the approaches of NCEP/ATP III criteria's. RESULTS: The prevalence of metabolic syndrome was of 27 cases (32 ,1 %), 21 cases (77,7 %) in ages among 26-40 years. The alcohol consumption (91 ,6 %), LDL-C (64,3 %), high systolic arterial pressure (59,5 %), obesity (56,6 %) and high triglycerides (55,9 %) were the principal's cardiovascular factors risk detected. The biochemical parameters were significantly higher in the men with clinical diagnosis of metabolic syndrome in comparison with those that didn't present the syndrome (p < 0.05). CONCLUSION: To weigh that the prevalence of metabolic syndrome was not so high, the factors of cardiovascular risk in an individual way were high, considering that the hard-working population is young is necessary to implement programs of prevention and changes of lifestyles to minimize the risk of coronary illness and vascular brain that lead to labour s disability.

Síndrome metabólico y otros factores de riesgo cardiovascular en trabajadores de una planta de policloruro de vinilo / Metabolic syndrome and other factors cardiovascular risk in workers of a plant of vinyl polychloride

Objetivo Establecer la prevalencia de Síndrome Metabólico y otros factores de riesgo cardiovascular en una población de trabajadores masculinos del área operativa de la planta de policloruro de vinilo de un complejo petroquímico, en el occidente de Venezuela. Métodos Estudio descriptivo, transversal realizado con 84 trabajadores a los cuales se les determinó talla, peso, presión arterial, circunferencia abdominal, índice de masa corporal, hábitos alcohólicos, tabáquicos y consumo de medicamentos. Adicionalmente se tomaron 10 ml de sangre venosa para glicemia en ayunas, colesterol total y HDL-C, los valores de LDL-C y VLDL-C. El diagnostico del síndrome metabólico se realizo bajo los criterios de NCEP/ATP III. Resultados La prevalencia de síndrome metabólico fue de 27 casos (32,1 por ciento), de los cuales 21 (77,7 por ciento) se encontró en edades entre 26 - 40 años. El consumo de alcohol (91,6 por ciento), LDL-C elevado (64,3 por ciento), presión arterial sistólica elevada (59,5 por ciento), obesidad (56,6 por ciento) e hipertrigliceridemia (55,9 por ciento), constituyeron los factores de riesgos cardiovascular más relevantes en esta población trabajadora. Los parámetros bioquímicos estuvieron significativamente más elevados en los hombres con diagnóstico clínico de síndrome metabólico en comparación con los que no presentaron el síndrome (p< 0,05). Conclusión A pesar que la prevalencia de síndrome metabólico no fue tan alta, los factores de riesgo cardiovascular de manera individual estuvieron elevados, considerando que la población trabajadora es joven, amerita la implementación de programas de prevención y cambios de estilos de vida para minimizar el riesgo de enfermedad coronaria y cerebro vascular que conducen a discapacidad laboral.

[A profile of workers' health in an olefins plant in the Venezuelan state of Zulia]. / Perfil de Salud de los Trabajadores de una Planta Procesadora de Olefinas del Estado Zulia, Venezuela.

OBJECTIVE: Determining the profile of health for people working in an olefin plant. METHODS: This was an observational, descriptive study carried out on 142 workers from technical-administrative, operator and maintenance areas. Each worker's employment and medical history was examined; they had a physical examination and laboratory, audiometric and visual tests. The degree of obesity was determined by WHO classification; cardiovascular risk was classified by using the European Societies' risk table. RESULTS: The workers had a mean age of 36,2+/-6,9. The operators presented mean weight and systolic pressure which was higher than that of the rest of the workers. A high risk factor frequency was determined for cardiovascular pathologies: alcohol consumption (89,4 %), obesity (62,7 %), hypertriglycerides in the blood (46,5 %) and high systolic pressure (45,1 %); operators were the most affected workers. A moderate frequency of workers having altered hepatic enzymes, AST (38 %) and GGT (29,6 %) were observed The most frequently encountered pathologies were ametropia (64,1 %), dyslipidaemia (57,8 %), obesity (50 %) and hypertension (45,1 %). Workers aged more than 40 presented higher systolic pressure. A significant correlation between IMC and systolic pressure was found. CONCLUSION: A high prevalence of cardiovascular risk factors was found. Health-care should be designed and promoted and action should be taken towards modifying lifestyles, aimed at reducing the risk of cardiovascular disease.

Perfil de Salud de los Trabajadores de una Planta Procesadora de Olefinas del Estado Zulia, Venezuela / A profile of workers' health in an olefins plant in the Venezuelan state of Zulia

Objetivo: Determinar el perfil de salud de los trabajadores de una Planta procesadora de Olefinas del Estado Zulia. Métodos: Se realizó un estudio observacional descriptivo, evaluando a 142 trabajadores de las áreas administrativa- técnica, operaciones y mantenimiento. A cada trabajador se le realizó una historia médico ocupacional, examen físico, exámenes de laboratorio, audiometría y evaluación visual. El grado de obesidad se determinó mediante la clasificación de la OMS, el riesgo cardiovascular se estableció aplicando las tablas de riesgo de las Sociedades Europeas. Resultados: El promedio de edad de los trabajadores fue de 36,2 ± 6,9 años. Los individuos del área de operaciones mostraron promedio de peso, y tensión arterial sistólica más elevada que el resto de las áreas. Se determinó una alta frecuencia de factores de riesgo cardiovascular predominando el consumo de alcohol (89,4 por ciento), obesidad (62,7 por ciento), hipertrigliceridemia (46,5 por ciento), y presión arterial sistólica elevada (45,1 por ciento); siendo los operadores los más afectados. Se encontró una frecuencia moderada de trabajadores con enzimas hepáticas alteradas AST (38 por ciento) y GGT (29,6 por ciento). Las patologías más frecuentes fueron ametropia (64,1 por ciento), dislipidemia (57,8 por ciento), obesidad I (50 por ciento), e hipertensión (45,1 por ciento). Los mayores de 40 años mostraron cifras de tensión arterial sistólica más elevadas. Se encontró una correlación positiva y significativa entre IMC y tensión sistólica. Conclusión: Existe una alta prevalencia de factores de riesgo cardiovascular. Se recomienda diseñar y aplicar acciones de promoción de la salud, encaminadas a modificar los estilos de vida para disminuir el riesgo de enfermedad cardiovascular.
