Utilizing the data of the 2010 survey on the health awareness of young migrant workers，this article investigates the condition of health integration and its influencing factors of the new-generation migrant workers. Results show that 21. 4% of the new-generation migrant workers rate their current health condition being better than that before migration，while 64.0% and 14.6% of the population regard their current health status being the same or worse respectively. The multi-variate analyses demonstrate that health condition tends to become better among men，among those whose sleeping time is at least 8 hours，and among those whose parents are both healthy，whereas health condition trends to become worse among the young migrant workers whose floating time is 5 years or over，and among those under greater pressure. The degree of health integration of the new-generation migrant workers is quite low，and therefore it is necessary to take actions to promote their health.
