Abstract： Objective:To investigate the development trend of physical examination volume and revenue in health-checkup institutions in China from 2010 to 2019.Methods:In this longitudinal study, the annual income, annual physical examination volume and other indicators reflecting institutional size were collected with questionnaire from 374 health-checkup institutions in the year of 2010, 2015 and 2019. The geometric mean method is used to calculate the compound annual growth rate (CAGR) of the annual physical examination volume, annual income, mean per capita cost from 2010 to 2015 and 2015 to 2019.Results:The annual physical examination volume of health-checkup institutions increased from 1.81 (1.00, 3.20) ×10 4 person times in 2010 to 5.08(3.50, 7.28)×10 4 person times in 2019; the CAGR of the physical examination volume from 2010 to 2015 was 14.04%(8.14%, 23.78%), and it was 9.49%(3.39%, 19.07%) from 2015 to 2019. The annual revenue increased from 768.73 (350.00, 1 623.75) ×10 4 yuan in 2010 to 3 500.00 (1 997.73, 6 818.54) ×10 4 yuan in 2019; the CAGR of annual revenue from 2010 to 2015 was 25.75% (15.17%, 35.09%), and it was 15.67% (8.78%, 26.11%) from 2015 to 2019. The mean per capita cost increased from 434.26 (278.82, 666.66) yuan in 2010 to 755.80 (506.90, 1 005.42) yuan in 2019; the CAGR of the mean per capita cost was 9.82% (1.71%, 17.10%) from 2010 to 2015, and it was 5.37% (0.95%, 10.46%) from 2015 to 2019. Conclusion:From 2010 to 2019, health-checkup institutions in China developed rapidly, and the CAGR of the annual physical examination volume, annual revenue, mean per capita cost are high.
