ABSTRACT
Background Work-related musculoskeletal disorders (WMSDs) are one of the major occupational health problems in the world. Pharmaceutical industry is an important part of China's national economy. At present, there are few related studies reported at home and abroad. Objective To investigate the status and influencing factors of WMSDs in chemical pharmaceutical industry. Methods A cross-sectional epidemiological survey was conducted among all workers from three chemical pharmaceutical enterprises in Guangzhou. The Musculoskeletal Disorders Questionnaire was used to collect information on demographic characteristics, symptoms of musculoskeletal disorders, types of work, work organization, and and work postures. Multiple logistic regression method was used to analyze the risk factors of WMSDs in chemical pharmaceutical workers. Results In this study, 563 workers were selected as subjects. The total prevalence rate of WMSDs symptoms in the chemical pharmaceutical workers was 43.9% (247/563), and the leading body part-specific prevalence rate from high to low was 34.3% in the lower back, 24.3% in the upper back, 24.0% in the shoulders, and 23.8% in the neck. The prevalence rate of WMSDs symptoms in multiple body parts (30.0%) was 2.16 times higher than that in single body part (13.9%), and the prevalence rate of WMSDs symptoms in four body parts was the highest (11.4%). The results of multiple logistic regression analysis showed that age ≥50 years (reference age <30 years) (OR=2.140, 95%CI: 1.054-4.345), often or very often (reference never/rarely) long-time head rotating (OR=2.695, 95%CI: 1.753-4.142) and long-time keeping arms above shoulders (OR=1.902, 95%CI: 1.108-3.265) increased the risk of reporting WMSDs symptoms (P<0.05). Regarding education level, workers with high school and technical secondary school (OR=0.333, 95%CI: 0.175-0.636) or college and above (OR=0.413, 95%CI: 0.216-0.790) education had a lower risk of reporting WMSDs symptoms than those with middle school or below (P<0.05). Conclusion The prevalence rate of reporting WMSDs symptoms in chemical pharmaceutical industry is high, the involving body parts are lower back, upper back, shoulders, and neck, and reporting simultaneous occurrence of WMSDs symptoms in multiple body parts is common. The chemical pharmaceutical manufacturers can reduce the risk of WMSDs by strengthening the training on workers' ergonomics knowledge, paying attention to the less educated personnel, protecting the elderly workers, and avoiding awkward work postures, like rotating head for a long time and raising arms over shoulders.
ABSTRACT
Objetivo: Determinar si existe relación entre el tipo de trabajo en empleados públicos y el desarrollo de síndrome metabólico. Materiales y métodos: Estudio de tipo descriptivo transversal observacional. La muestra son los empleados del Jurado Nacional de Elecciones (JNE) sede Lima, que acuden a su evaluación médico ocupacional 2013 y a quienes se aplica los criterios del panel (ATP-III), modificado (2005). La recolección de datos fue obtenida de la historia clínica ocupacional de los empleados en estudio. Resultados: Se evaluó a 322 empleados, cuya prevalencia de síndrome metabólico fue 2,17%, correspondiendo al sector administrativo 2,28% (p =1,0) frente al sector no administrativo que no presentó casos. La edad con mayor prevalencia con síndrome metabólico fue de 30 a 39 años (3.7%), p de 0,495. El estudio encontró significancia estadística en relación con el género masculino (p =0,019). Conclusiones: En los empleados administrativos del JNE, no se encontró relación entre el tipo de trabajo y el desarrollo de síndrome metabólico. El género masculino sí tuvo relación con el síndrome metabólico.
Objective: To determine the relationship between public employees' type of work and the development of metabolic syndrome. Materials and methods: Descriptive cross-sectional observational study. The sample consisted of employees of the National Electoral Board (JNE), Lima office, who underwent their 2013 occupational medical evaluation and were assessed according to the Adult Treatment Panel III (ATP - III) criteria, as amended in 2005. Data collection was obtained from the employees' occupational medical records. Results: Three hundred twenty-two (322) employees were evaluated. The metabolic syndrome prevalence was 2.17%. The administrative sector was affected in 2.28% (p = 1.0) compared to the non-administrative sector which showed no cases. The highest prevalence of metabolic syndrome was found in 30 - 39 years old employees (3.7%) (p=0.495). The study showed statistical significance in relation to male gender (p= 0.019). Conclusions: In administrative employees of the JNE, there was no relationship between the type of work and the development of metabolic syndrome. Male gender was associated with metabolic syndrome.
