To promote habitual participation in physical activity, a 3-month program for lifestyle physical activity intervention (L group) and structured exercise intervention (E group) was carried out in a community in Okayama Prefecture. One year later, we compared the two intervention groups in terms of cost-effectiveness and behavioral change in habitual physical activity. A total of 250 subjects voluntarily participated in the lifestyle physical activity intervention ; and a total of 42 subjects participated in the structured exercise intervention. The number of participants decreased to 115 (46%) and 21 (50%), respectively, one year later. However, the proportion of subjects who practice endurance exercise increased significantly in both L and E groups ; and an additional 35 subjects (30%) started to practice endurance exercise in L group and 5 (24%) in E group after the interventions. The cost-effectiveness for a person newly starting the endurance exercise practice in the L group intervention was 29,206 yen ; and the E group intervention was 124,731 yen, a ratio of 1/4.3. The study suggests that the cost-effectiveness for the lifestyle physical activity intervention was 4 times better than the structured exercise intervention.

Purpose: The present study aims to evaluate the effect of analgesics in cancer patients based on their pain descriptions. Methods: The relationship between the words that patients used to describe their pain due to cancer and the efficacy of treatment with analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs) or opioids was evaluated. Results: We recorded 529words that were used by 164patients to describe their pain and pain quality and classified them into 108types of pain.For patients who used the actual word 'dull' or one with a similar meaning, treatment with opioids was effective. However, treatment with opioids was less effective in patients who used words such as "numb" and "tingling". Conclusion: We were able to gain a good understanding of cancer pain by listening to the actual words that patients used when complaining of pain. These findings suggested that we could choose a suitable medication through evaluation of the actual words cancer patients used to describe their pain and successfully relieve their pain.
