In order to evaluate the intervention effect of the school-based salt reduction model, 28 primary schools were selected in Shandong Province in September 2014 and randomly divided into intervention group (1 361 students, 1 306 parents) and control group (1 364 students,1 340 parents). A series of "small hands and big hands" salt reduction intervention activities were conducted in intervention group for 8 months. After the intervention, the total awareness rate of salt reduction knowledge, the total holding rate of related beliefs and the total reporting rate of related behaviors were 70.65%, 80.30% and 67.03% among students, and 85.66%, 93.77% and 87.93% among parents, in the intervention group, which were higher than those in the control group (37.12%, 66.52% and 50.07% among students; 55.11%, 87.52% and 57.96% among parents) (all为评价以学校带动家庭的减盐模式的干预效果，于2014年9月在山东省抽取28所小学，随机分为干预组（学生1 361名，家长1 306名）和对照组（学生1 364名，家长1 340名），干预组开展8个月的"小手拉大手"系列减盐干预活动。干预后，干预组学生减盐知识总知晓率、减盐相关信念总持有率和减盐相关行为总报告率分别为70.65%、80.30%、67.03%；家长分别为85.66%、93.77%、87.93%，均高于对照组（学生分别为37.12%、66.52%和50.07%；家长分别为55.11%、87.52%和57.96%）（
