Incidence of acute low-back injury among older workers in a cohort of material handlers

Abstract

Injuries to the low back are the most common cause for injury claims among material handlers. Previous studies have shown conflicting results about how age affects risk of low-back injury. This study describes the incidence of acute low-back injury by age, gender, length of employment, and lifting intensity measured by job classification in a cohort of material handlers. The cohort included all material handlers employed at a large home improvement retail chain in California from 1989 through 1994. The cohort accrued approximately 50,000 full time equivalents over the study period. A total of 2152 low-back injuries were reported during the study period. Compared to workers aged younger than 45, the crude rate ratio for workers aged 45 to 54 was 0.78, and for workers aged 55 and above was 0.84. However, this age difference was not apparent among length of employment strata or among jobs with low or medium lifting intensity. A higher proportion of workers over the age of 55 missed work time because of their injury, and workers over 45 had a higher average number of lost workdays per injury. This research indicates that workers over age 55 had similar injury rates to workers younger than age 55, even when considering lifting inten...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
