Methods Two communities were selected where the external population was more concentrated. A group of 234 parents of 0 to 4 years old migrant children who lived more than six months in the City. Investigation was made before the health education, and after multi-form intervention was done the effect of the intervention was evaluated.
Results Before and after the intervention, the rate of the migrant children' parents about EPI knowledge increased from 43.47% to 86.17% (χ²=1 028.87, P<0.01), the rate of active attitude from 46.26% to 85.15% (χ²=314.10, P<0.01), the rate of active behavior from 42.95% to 92.95% (χ²=268.61, P<0.01).
