Health-related quality of life and sickness absence in community nursing home employees: randomized controlled trial of physical exercise.
BACKGROUND It is a common belief that physical exercise at the workplace decreases subjective health complaints and reduces sickness absence , but this is not supported by previous r and omized studies . AIMS To evaluate the effectiveness of physical exercise at the workplace . METHODS One hundred and twenty-nine employees in a community-based nursing home for the elderly were r and omized into physical exercise or control groups . A weekly exercise class consisting of light aerobic exercise , muscle strengthening and stretching was held for a 6-month period . The control group was told to continue their ordinary activity . The main outcome measures were aerobic fitness ( UKK , walking test ) , health-related quality of life ( COOP/WONCA ) and sickness absence . Blinded assessment s were carried out at baseline and following the 6-month intervention . Complete sickness absence data were collected from a community register for two comparable 7-month periods . RESULTS The average number of exercise sessions was 12 ( 0 - 26 ) . Self-reported physical activity increased in the intervention group compared with the control group ( P < 0.01 ) . Aerobic fitness improved in both groups ( P < 0.01 ) . Mean sickness absence increased from 6.8 to 15.6 days in the exercise group and from 10.4 to 14.5 in the control group . No differences between groups were found for aerobic fitness , health-related quality of life or sickness absence . CONCLUSION The intervention neither improved health-related quality of life nor reduced sickness absence
