Low back and neck-shoulder pain : Work and heritability

摘要: Low back pain (LBP) and neck-shoulder (NSP) represent a large public health problem being common disorders that often lead to negative consequences for the individual costs Society. The main goal of thesis is explore how factors relating aetiology, i.e. influences genetic work-related physical load, as well in terms sickness absence are associated with different combinations LBP NSP. This based on three data materials; MUSIC-Norrtalje study, STAGE Swedish orchestra study. Paper I used study material during 5-year period (1995-2001) subjects consistent Solely LBP, NSP, Concurrent NSP (n= 817). results showed odds ratio was OR 1.69 (95% confidence interval 1.14-2.51) long-term 2.48 CI 1.324.66), compared those or In paper II, estimate heritability using classical twin methodology 20,946). 60% total variance could be explained by additive effects, which twice (30%) more than (24%).
