Men who are continually active at work may have a decreased risk of prostate cancer

Date:2/12/2008

Men with jobs that require them to be physically active may be getting benefits beyond salary and health insurance - they may be at a decreased risk of developing prostate cancer, according to a study at UCLAs Jonsson Cancer Center.

Researchers studied more than 2,100 men who worked at the Rocketdyne facility in the San Fernando Valley, many of whom were exposed to radiation and chemicals that may have increased their risk for certain cancers. The research team identified 362 men who developed prostate cancer and compared them to 1,805 men of similar age and socioeconomic status who did not get prostate cancer.

The study, done in conjunction with researchers at the Olive View-UCLA Education and Research Institute and the University of Michigan, appears in the February issue of the journal Cancer Causes Control.

The message from this study for today is that if youre more active, you may be able to prevent this cancer from happening, said Beate Ritz, a Jonsson Cancer Center researcher, an associate professor of epidemiology in the UCLA School of Public Health and the studys senior author. If you have a desk job, do something physically active to counterbalance it. The case-control study nested within a larger cohort of more than 10,000 subjects focused on men who worked at the nuclear and rocket engine testing facility from the 1950s to the early 1990s. The cases of prostate cancer were diagnosed between January 1988 and December 1999. Researchers obtained cancer incidence data for the workers from the California Cancer Registry and seven other cancer registries in neighboring states where workers may have moved after retirement.

Data from Rocketdyne company records was used to construct a job exposure matrix that ranked job descriptions by the amount of physical activity required and any harmful exposures the workers might have experienced.

Physical activity was separated into jobs with low, moderate and high
