P181 Developing an intervention program to reduce ergonomic risk factors among office employees

BACKGROUND: Work-related musculoskeletal disorders are the most common occupational health hazards. In the flour production industry, the fast pace of work, high frequency of repetitive movements, manual handling of loads, and awkward postures put a lot of pressure on the worker’s body. OBJECTIVE: Given the high exposure of the workers of the flour production industry to ergonomic risk factors, this study aimed to reduce the rate of musculoskeletal disorders among a group of flour factory workers through ergonomic interventions. MATERIALS AND METHODS: This interventional study was performed using the census method on the eligible workers of a flour factory. An ergonomic intervention program was planned and implemented with the goal of reducing musculoskeletal disorders. The effectiveness of the program was evaluated by measuring the prevalence of musculoskeletal disorders before and six months after the interventions. RESULTS: Before the intervention, musculoskeletal disorders were most prevalent in the lower back, arms, shoulders, legs, thighs, knees, neck and wrists, respectively. Evaluation of the prevalence of musculoskeletal disorders after the intervention showed the positive effect of the ergonomic intervention program on musculoskeletal disorders in the neck, shoulders, lower back, thighs, knees, and legs (P < 0.05). CONCLUSION: Engineering and management interventions implemented in this study led to a significant reduction in the level of ergonomic risk factors and a reduced rate of musculoskeletal disorders among workers of different units in the flour factory.

Ergonomic Risk

Prevention of health disorders and sexual development of society is a priority area of hygiene and preventive medicine. The introduction of information and communication technologies into the educational process is a new risk factor for the development of disorders of the musculoskeletal system in adolescents. Purpose of the study: assessment of ergonomic risk factors for the development of disorders of the musculoskeletal system in adolescents using personal electronic computers as teaching aids. Objects of research: sanitary-hygienic and ergonomic factors of learning conditions with the use of personal computers and the state of the musculoskeletal system of college students. Research in accordance with the requirements of bioethics, after signing the informed consent and their parents. The hygienic factors of the learning environment and the ergonomic characteristics of furniture (tables, work chairs) in computer science classes of the Saratov college were studied. Their assessment is given for compliance with sanitary and epidemiological requirements and anthropometric indicators of students. A questionnaire survey and physical examination of 308 adolescents were carried out to identify complaints and assess the condition of the musculoskeletal system. It has been established that the organization and ergonomic characteristics of workplaces equipped with electronic computers fully comply with hygienic and ergonomic requirements. This is the cause of postural disorders and the development of disorders of the condition of the musculoskeletal system of students. A high prevalence of clinical signs of disorders of the musculoskeletal system among adolescents was revealed. It has been established that compliance with ergonomic requirements in the organization of workplaces when using personal electronic computers is a prerequisite for the primary prevention of disorders of the musculoskeletal system in adolescents. To solve this problem, first of all, it is necessary to provide educational institutions with modern furniture that meets ergonomic requirements.
