Objective To understand the health-related life quality and its influencing factors in elderly community residents in Shanghai， and to provide reference for improving their life quality.
Methods During April to June 2021， a cross-sectional survey was conducted in five selected community health care centers， from Baoshan District， Minhang District， Songjiang District and Pudong New District of Shanghai， respectively. The elderly residents aged 65 and over who received physical examination were face-to-face interviewed using EQ-5D-5L scale. SPSS 26.0 and Stata 16 were used for statistical analysis. Binary logistic regression， multiple linear regression and Tobit regression were used to analyze influencing factors of each dimension in EQ-5D scale， EQ-VAS score and health utility value.
Results A total of 1302 elderly residents were included in the study， and the proportions of problems in the five dimensions of EQ-5D-5L scale were pain/discomfort （13.9%）， mobility （9.1%）， daily activity （5.8%）， self-care ability （4.8%） and anxiety/depression （3.6%）， while age was a factor influencing problems in each dimension. The average score of EQ-VAS was 84.28±10.32， and the average health utility value based on Chinese population was 0.97±0.08， which was higher than the rest of the country. Tobit regression analysis showed that female （t=-3.96， P<0.001）， age group over 75 （t=-5.28， P<0.001）， high school education or above （t=-2.53， P=0.012）， chronic disease （t=-5.12， P<0.001） had poor quality of life （P<0.05）.
Conclusion The overall quality of life of the elderly in Shanghai community is good， but the quality of life in the elderly women and in the group suffering from chronic diseases is relatively poor. It is necessary to pay more attention to the key populations to improve their health status.
