This 12-month aerobic jumping and circuit training intervention completely prevented femoral neck bone loss in premenopausal breast cancer patients, whereas no effect on BMD was seen in postmenopausal women.

BackgroundScreening for colorectal cancer (CRC) with guaiac-based faecal occult-blood test (FOBT) has been reported to reduce CRC mortality in randomised trials in the 1990s, but not in routine screening, so far. In Finland, a large randomised study on biennial FOB screening for CRC was gradually nested as part of the routine health services from 2004. We evaluate the effectiveness of screening as a public health policy in the largest population so far reported.MethodsWe randomly allocated (1:1) men and women aged 60–69 years to those invited for screening and those not invited (controls), between 2004 and 2012. This resulted in 180 210 subjects in the screening arm and 180 282 in the control arm. In 2012, the programme covered 43% of the target age population in Finland.ResultsThe median follow-up time was 4.5 years (maximum 8.3 years), with a total of 1.6 million person-years. The CRC incidence rate ratio between the screening and control arm was 1.11 (95% CI 1.01 to 1.23). The mortality rate ratio from CRC between the screening and control arm was 1.04 (0.84 to 1.28), respectively. The CRC mortality risk ratio was 0.88 (0.66 to 1.16) and 1.33 (0.94 to 1.87) in males and females, respectively.ConclusionsWe did not find any effect in a randomised health services study of FOBT screening on CRC mortality. The substantial effect difference between males and females is inconsistent with the evidence from randomised clinical trials and with the recommendations of several international organisations. Even if our findings are still inconclusive, they highlight the importance of randomised evaluation when new health policies are implemented.Trial registration002_2010_august.

This study aimed to develop a theoretical basis for the promotion of school staff's occupational well-being. The 'Content Model for the Promotion of School Community Staff's Occupational Well-being' describes the four aspects of the promotion of occupational well-being ('working conditions', 'worker and work', 'working community' and 'professional competence') as well as the functionality and structure of the model. The content model was examined empirically by means of a structural equation model. The project was developed with school staff and occupational health nurses and implemented in 2001-2004. The target group consisted of the staff of 12 comprehensive schools in Eastern Finland in 2002 (n = 211) and 2004 (n = 266). The data were collected using a 'well-being at your work index' questionnaire at both times. A structural equation model for the school staff's occupational well-being, i.e. the 'Occupational Well-being of School Staff Model' (baseline OWSS Model: Study I in the year 2002), was produced. The model was tested with the 2004 data. Based on this, the model was further developed into the final OWSS Model (Study II). The theoretical Content Model for the Promotion of School Community Staff's Occupational Well-being can be used as a framework for planning, implementing and evaluating school staff's occupational well-being.

By 2007, organized colorectal cancer screening covered one-third of the target population in Finland. Implementation of screening measured with response rate was successful and met the criteria for a public health programme, but performance in terms of positive predictive value needs monitoring.
