AIMS: Low back pain (LBP) is a major public health problem in both Norway and Sweden. The aim of the study was to estimate the prevalence of LBP and sickness absence due to LBP in two neighbouring regions in Norway and Sweden. The two areas have similar socioeconomic status, but differ in health benefit systems. METHODS: A representative sample of 1,988 adults in Norway and 2,006 in Sweden completed questionnaires concerning LBP during 1999 and 2000. For this study only individuals in part or full time jobs, (n = 1,158 in Norway and n = 1,129 in Sweden) were included. RESULTS: In Norway the lifetime prevalence was 60.7% and in Sweden 69.6%, the one-year prevalence was 40.5% and 47.2%, and the point prevalence 13.4% and 18.2% respectively. There was a significantly higher risk of reporting LBP in Sweden, even after controlling for gender, age, education, and physical workload. There was no difference in risk of self-certified short-term sickness absence (1-3 days), but it was a 40% lower risk of sickness absence with medical sickness certification in Sweden compared with Norway. CONCLUSION: The prevalence of LBP was higher in the Swedish area than in the Norwegian. The risk of self-certified sickness absence, however, showed no differences and the risk of medically certified sickness absence was lower in the Swedish area. This contradiction might partly be explained by the economical 'disincentives' in the Swedish health compensation system. [ABSTRACT FROM AUTHOR]

Subjects and design: The study was based on the total patient sample (n =110) of a randomized controlled trial comparing two intervention methods advising cardiovascular high-risk men of lifestyle changes in general practice. Behaviour and risk factor changes during the one-year intervention study were analysed using multiple regression and logistic regression analyses with the above-mentioned independent variables. Setting: Twenty-two general practice centres in the county of Hordaland, western Norway. Results: Self-efficacy of increased physical exercise was the only variable significantly related to exercise change. Age and self-efficacy were statistical significant predictors of smoking cessation success. None of the independent variables was statistically significantly related to blood pressure or cholesterol change. Educational level related negatively, although statistically insignificantly, with total risk change. Conclusion: The study confirms the importance of self-efficacy in both human behaviour and motivation for behaviour change. Objectives: The objectives of the study were to explore the impact of possible predictors for cardiovascular risk behaviour change; predictors such as education, age, self-efficacy, doctors' interpersonal skills, and number of appointments.
