Objective To estimate the health life expectancy （HALE）of residents aged 18 years and over in Suzhou, and to provide scientific basis for the establishment of health assessment system and the development of accurate prevention and control in Suzhou. Methods A total of 6208 adults aged 18 and above were chosen by multi-stage stratified random cluster sampling in 2019 to gather self-reported health data. Life expectancy table was based on annual official population and mortality data. Sullivan’s method and Hierarchical Ordered Probit（HOPIT）model were used to calculate HALE. Results In 2019, the HALE of the 18-year-old adults in Suzhou is 36.30 years, and that of the 60-year-old group is 7.80 years. The percentage of life lost is 45.17% and 69.56% respectively. With the increase of age, the percentage of life loss increases gradually. The loss of HALE and the percentage of life lost due to disability in all age groups of men were lower than those of women, and the difference increases with age. Conclusion The health level of female adults in Suzhou is lower than that of men, and the health problems of the elderly have a major impact on the quality of the rest of their lives.
