Objective To observe the effect of comprehensive intervention on the incidence of lactation galactostasis in communities from the perspective of preventive medicine， so as to prevent the occurrence of the mammary ducts obstruction disease.
Methods A total of 400 women in the early stage of pregnancy were selected from four communities. Those in two communities were set up as the intervention group. Comprehensive intervention for the prevention and treatment of mammary ducts obstruction disease during pregnancy and "Six-step recanalization manual therapy" practical guidance were conducted on the intervention group. The pregnant women from the other two communities were the control group， who received no intervention or guidance training. The two groups were followed up at 1 month， 3 months and 5 months postpartum， and the occurrence of mammary ducts obstruction disease was investigated and interventions were carried out.
Results The incidence of galactostasis in the intervention group was 26.0%， 10.6% and 5.1%， respectively at 1， 3 and 5 months after delivery， and the incidence of galactostasis in the control group was 38.0%， 22.2% and 8.3%， respectively. The incidence of galactostasis at 1 month and 3 months after delivery was statistically different （P<0.05）， while the incidence of galactostasis 5 months after delivery was not statistically different （P>0.05）. The protection rates of comprehensive intervention on galactostasis were 31.58%， 52.25% and 38.55%， respectively.
Conclusion Publicity and education work of prevention and control of the mammary ducts obstruction disease and "Six-step recanalization manual therapy" practical guidance can effectively reduce the occurrence of plugged mammary ducts， and therefore should be promoted.
