    The aging-related problems China faces are complex. One of the most important of these issues is depression. The purpose of this study is to clarify the relationship between depression and the physical, mental and social environment of elderly urban Chinese. We conducted a health survey of elderly Chinese aged 65 years or over living in Tianjin. The subjects included 65 males (70.8±5.1 years old) and 69 females (71.2±5.3 years old). Their depression status was evaluated according to the Chinese version of the Geriatric Depression Scale short form (GDS-S). Using a questionnaire survey, we evaluated physical factors (namely measurement of physical fitness and self-rated physical strength), lifestyle factors, mental factors (subjective health, purpose of life), and social environmental factors (social support networks : Measurement of Social Support-Elderly) and other home background factors. The male subjects recorded a GDS-S score of 3.4±3.5 (score mean±SD) and the female subjects (3.1±3.5). Multivariate logistic regression analysis was used to analyze the data. Self-rated physical strength (odds ratio=0.16, 95% confidence interval=0.03-0.85) appeared to be closely related to a decrease in GDS-S score. Life events and a decline in physical strength are inevitable. However, we demonstrated that inhibition of depression increased self-rated physical strength. In China, there are aggressive moves to expand measures aimed at maintaining the strength of elderly people. However, it is important to extend healthy life expectancy measures aimed at improving QOL rather than focusing merely on longevity.

    Purpose : Concerning the effect of high temperature, knowledge is limited in developing countries, because public health infrastructure is not yet established in these countries including those in Asia in particular. In this study, we analyzed the effect of extreme temperature in three cities in China.
    Methods : We conducted the study in three cities in China using distributed lag nonlinear models (dlnm). The “dlnm” is a flexible package to evaluate a non-linear effect itself and its lag simultaneously. We obtained a data from database made by the Ministry of Health in China for daily number of deaths from 1998 to 2002.
    Results : Regarding high temperature, mortality has increased acutely and the effect did not last long. Regarding cold temperature, the mortality has tendency to stay to be more than 1.0 for more than 10 days in Guangzhou and in Nanjing. The RR for Nanjing at lag=0, and temperature=0 showed the different pattern from previous research.
    Conclusion : The result showed that heat effect observed in the three Chinese cities and the cold effect in Guangzhou and Harbin were consistent with the previous researches. The cold effect of Nanjin was not consistent in the point of showing direct impact in lag0, 0°C.
