Objective To estimate healthy life expectancy of residents aged 30 and above in Jianyang, Sichuan province, and comprehensively evaluate the health status of the population, so as to provide reference and basis for the formulation of health-related public policies. Methods The population data, death data and health status data of Jianyang city in 2018 were collected, and the self-rated health life expectancy and life expectancy without chronic diseases of residents aged 30 and above were calculated by Sullivan method, and their proportion in life expectancy was calculated. Results A total of 4 482 residents aged 30 years and above were included in Jinyang city, of whom 3 989 were self-rated healthy, accounting for 89.00% of self-rated health, and 1 988 were suffering from chronic diseases, with a chronic disease prevalence rate of 44.36%. In the age group of 30-64, the self-rated health life expectancy of women was significantly higher than that of men (P<0.05), and in the age group of 40-44, the life expectancy without chronic diseases of women was significantly lower than that of men (P<0.05), and the differences were not statistically significant when comparing different genders in other age groups (P>0.05). With the increase of age, the proportion of residents’ self-rated health and the proportion of life expectancy without chronic diseases in healthy life expectancy gradually declined. Conclusions The chronic disease has become the main factor affecting the health of middle-aged and elderly population, especially female population. It is suggested that active measures should be taken to deal with chronic diseases and the elderly health support system should be strengthened to improve healthy life expectancy of residents in Jianyang city.
