Objective  To understand the life expectancy and cause-eliminated life expectancy of residents in Pudong new district of Shanghai during 2005−2020 and provide reference to the adjustment of health resource distribution.

  Methods  Abridged life table and cause eliminated life table were used to calculate the life expectancy and cause-eliminated life expectancy of residents in Pudong, and temporal trend of life expectancy were evaluated by using software Join-point.

  Results  The life expectancy of residents in Pudong was 84.76 years in 2020, and the life expectancy was 82.58 years in men and 87.01 years in women. The growth of life expectancy of residents in Pudong remained from 2005 to 2020, with an average annual increase of 0.25 years. In the past 16 years, the life expectancy loss caused by respiratory diseases and injury showed a downward trend, and the life expectancy loss decreased from 1.50 years and 1.01 years to 0.79 years and 0.70 years, respectively. The life expectancy loss caused by tumor kept stable. The life expectancy loss caused by circulatory diseases and endocrine nutritional and metabolic diseases showed an upward trend, and the life expectancy loss increased from 4.92 years and 0.38 years to 9.73 years and 0.68 years, respectively¹. The rank of cause-eliminated life expectancy remained stable from 2005 to 2020, and the top 6 disease were circulatory diseases, tumor, respiratory diseases, injury/poisoning, endocrine nutritional and metabolic diseases and digestive system diseases.

  Conclusion  The life expectancy in residents in Pudong increased steadily, which has reached leading levels of developed countries. Chronic and non-communicable disease was the main cause for the loss of life expectancy. There was an accelerating trend of loss of life expectancy caused by circulatory diseases and endocrine nutritional and metabolic diseases, and the loss of life expectancy caused by tumor remained at a high level. More effort should be made in the future prevention against these diseases.
