Work and back pain: a prospective study of psychological, social and mechanical predictors of back pain severity

Abstract

Studies relating occupational psychological and social factors to back pain have traditionally investigated a small number of exposure factors. The current study explored longitudinally a comprehensive set of specific psychological/social and mechanical work factors as predictors of back pain severity (defined as the product of back pain intensity and duration). Employees from 28 organizations in Norway, representing a wide variety of occupations, were surveyed with a follow-up period of 2 years. Several designs were tested: (1) cross-sectional analyses at baseline and follow-up; (2) prospective analyses with baseline exposure; (3) prospective analyses with average exposure over time [(T1+T2)/2]; and (4) prospective analyses with measures of change in exposure from T1 to T2. A total of 2808 employees responded at both time points. Fourteen psychological/social and two mechanical exposures were measured. Odds ratios (ORs) were computed by ordinal logistic regressions. Several psychological/social factors predicted back pain severity. After adjustment for age, sex, skill level, back pain severity at T1 and other exposure factors estimated to be potential confounders, the most consistent predictors of back pain were the protective...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.
