SawadaTokyo Gas Health Promotion Center, Tokyo, JapanIn Japan, cancer is the leading cause of death. Also, all over the world, cancer is one of the leadingcauses of death. Nowadays, a lot of evidences suggests, that physical activity or high cardiorespiratory fitnessmay prevent certain types of cancers. But, limited data are available on the relationship betweencardiorespiratory fitness and cancer mortality in Japanese. We evaluated the cardiorespiratory fitness and riskof cancer mortality of 9,039 Japanese men who were given a submaximal exercise test and a medicalexamination between 1982 and 1988. Cardiorespiratory fitness was measured using a cycle ergometer test,and maximal oxygen uptake was estimated. The mean follow-up period was slightly more than 16 years,producing a total of 148,491 person-years of observation. There were 231 deaths, with 123 deaths due tocancer. Relative risks and 95% confidence intervals (CI) for cancer mortality were obtained using the Coxproportional hazards model. Taking into consideration age, systolic blood pressure, body mass index, smokinghabit, and alcohol habit and using the lowest cardiorespiratory fitness group as the reference, the relative risksfor increasing quartiles of fitness were 0.75 (95% CI: 0.48 - 1.16), 0.43 (95% CI: 0.25 - 0.74), and 0.41 (95% CI:0.23 - 0.74); p for trend < 0.001. These results indicate that low cardiorespiratory fitness is an independent riskfactor for cancer mortality in Japanese men. It suggests that maintaining an active lifestyle may contribute tocancer prevention.338
