Objective To investigate migrant workers' medical compliance after receiving abnormal entry health examination results and relevant factors affecting compliance behavior, providing evidence to clinical treatment, nursing and health education. Methods 106 migrant workers who took part in entry health examination in our hospital and got abnormal results were accepted questionnaires and the relative factors were analyzed. Results 20 migrant workers had good compliance behavior, and 38 workers performed normally while 48 workers did bad. Age, gender, education, type of occupation, type of illness, and income all had influence on compliance behavior (P<0.01). Conclusion The recent condition of migrant workers' medical compliance on abnormal entry health examination results is not good. Therefore the country or province departments should carry out relative laws or policies, providing migrant workers with health support; Medical institutions should promote health education to improve migrant workers' health awareness and health behavior and reduce incidence of chronic diseases.
