Youth athletes are known to be at high risk of musculoskeletal (MSK) injuries. Children in developed countries are increasingly adopting a sedentary lifestyle. Although some risk factors related to sports activities have been reported, the effect of lifestyle (i.e. screen time behaviour) on MSK pain in youth athletes is not well known. This study aimed to examine the association of game playing and TV viewing with MSK pain among youth athletes. A self-administered questionnaire was mailed to youth athletes belonging to the Miyagi Amateur Sports Association. The final study population included 6,143 youth athletes (male, 71.1%; age range, 6–15 years). Multiple logistic regression analysis was used to examine the association of game playing and TV viewing behaviour with MSK pain. The point prevalence of MSK pain was 25.5%. The longest category of game playing time (≥3 h) was significantly associated with MSK pain as compared with the shortest category (<1 h) (odds ratio, 1.39; 95% confidence interval, 1.12–1.73, p = 0.003). There was no significant association between TV viewing time and MSK pain. These results suggest that game playing time might be an associated factor for MSK pain among youth athletes.  相似文献   

EDUCATION AND THE AGED: SOCIAL AND CONCEPTUAL CHANGES IN JAPAN     

Reiko W. Sekiguchi 《Educational gerontology》2013,39(4-5):277-293

Japan is moving into an aging society at a greater speed than any other country in the world has ever experienced. As this speed is very rapid, the concept of life in the aged life‐cycle stage which has emerged has not been fully established yet; here the cultural lag phenomenon is acutely observed. Among many possible activities, however, learning activities will be expected to have increasing popularity among aged persons as a source of happiness and inspiration for the fulfillment of their lives. Since not only young persons, but also aged persons, are involved in learning activities, the concept expressed by the term education is changing into a broader one to include the transmitting of values, knowledge, and skills through secondary communication.  相似文献
