Methods: Through multi?鄄stage cluster sampling, 2000 migrants were selected. These migrants centralized in factories, constructive area and entertainment area of Minghang District， Shanghai City were recruited into control and intervention team， respectively. The control group received the ordinary contraceptive service. Besides the ordinary service, the intervention group also received many sorts of interventions, including training, advisory service, follow?鄄up service, and so on. Twelve months after the intervention, evaluation survey were conducted, to evaluate the effects of contraceptive intervention program on the service and demand of family planning. Results: Total 2 001 migrants were surveyed in the baseline and 1 791 migrants were followed in the evaluation survey. There was significant increase on terms of the proportion of who possessed marriage certification among the intervention group（P＜0.000 1）. Evaluation survey showed that, as regards the proportion of services received, the intervention group was higher than the control group including counseling, technology, and follow?鄄up services. Multi?鄄logistic regression analysis showed that education, the workplace, the average monthly income, flow patterns and the household registration were the influencing factors on demand for educational and counseling services, while marital status, gender, and residence time in the current place also had an impact on communication and education service. Conclusions: The workplace?鄄based integrated intervention can improve migrants to accept family planning communication and education, counseling, follow?鄄up and technical services, but no influence on demand for educational and consulting services can be found.
