Effect of Lipid Profile Parameters on Noise Induced Hearing Loss.

Background: Noise induced hearing loss (NIHL) is an irreversible occupational disease among industrial workers. Recent studies have reported that changes in some metabolic factors such as the serum level of sugar and lipids might have a role in suffering from NIHL among workers exposed to noise. We designed this study to assess the association between lipid profile changes and NIHL occurrence among noise-exposed workers.

Impact of two ergonomics training on prevalence of upper and lower extremity complaints among nurses.

Background: Musculoskeletal disorders (MSDs) were known as one of the main occupational problems among health-care workers. However, we had some limitations and difficulties for transferring ergonomic concepts to the health-care workers, especially nurses due to heavy work task and insufficient time for that. This study compares the impacts of two ergonomic training methods (lecture and pamphlet) in nurses of an Iranian tertiary hospital on prevalence of their upper and lower extremity complaints.

Ergonomic intervention to reduce musculoskeletal disorders among flour factory workers.

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.

Occupational categories and cardiovascular diseases incidences: a cohort study in Iranian population.

Introduction: In spite of traditional cardiovascular risk factor, the different occupations can play an important role in cardiovascular disease (CVDs) incidence. We aimed to assess the correlation between the occupational classes, based on the International Standard Classification of Occupation (ISCO), and CVDs in Iran as a developing country.

Methods: We followed the 2440 men, aged 35-65 years and without history of CVDs over fourteen years; 2001 to 2015 during the Isfahan Cohort Study.

Functional parameters, wrist posture deviations and comfort: A comparison between a computer mouse and a touch pen as input devices.

Background: Performing common computer tasks such as pointing, clicking, and dragging requires repetitive movements that cause musculoskeletal disorders in the wrists and hands. Given the growing use of touch screens and touch pens, further studies on the ergonomics of these devices are needed. This study aimed to compare a touch pen and an ordinary computer mouse in terms of movement time, error rate, wrist posture, and comfort of use.
