Abstract: Background　In the process of achieving Healthy China 2030，one target of urbanization promotion is healthy urbanization. The national evaluation and prevention of sub-health of urban residents is of great significance for healthy urbanization. Although there have been some regional studies on sub-health status of Chinese urban residents，similar national studies are rather sparse. Objective　To explore the reliability and validity of Sub-health Measurement Scale Version 1.0（SHMS V1.0） in assessing the sub-health status of urban residents in China，and to analyze the sub-health status of this population. Methods　Multi-stage stratified sampling was used to select 17 339 urban residents from 6 geographical regions of China （East China，North China，Northeast China，South-central China，Southwest China and Northwest China） from December 2017 to October 2018. All participants attended a survey with the SHMS V1.0 scale，by which reliability and validity of the scale was assessed，and the sub-health status of this group was measured. The response rate of the survey was 86.89%（15 066/17 339）. Results　The Cronbach's α coefficient of the SHMS V1.0 was 0.922，and that of each of its three subscales was higher than 0.800，and that of every dimension was higher than 0.690. The odd-even reliability and front-rear reliability of the SHMS V1.0 were 0.955 and 0.822，respectively. Also，we found the scale had good discriminant validity and convergent validity. Exploratory factor analysis found that the cumulative variance explained by nine common factors was 64.16%，and these factors were completely consistent with the theoretical structure of the scale. Confirmatory factor analysis revealed good fitting effect. The detection rates of general，physical，mental and social sub-health were 68.06%（10 254/15 066），67.47%（10 165/15 066），65.96%（9 938/15 066） and 70.76%（10 660/15 066），respectively. There was significant regional difference in the detection rate of general，physical or social sub-health among the urban residents（P<0.05）. Women had a higher detection rate of mental sub-health，but a lower detection rate of social sub-health than men（P<0.05）. The detection rate of mental sub-health differed significantly across age groups（P<0.05）. And that of social sub-health also varied significantly across age groups（P<0.05）. Conclusion　The SHMS V1.0 scale demonstrated high reliability and validity for sub-health assessment of Chinese urban residents. The detection rate of sub-health differed by region，sex and age group，hence，targeted interventions are needed to improve sub-health.
