不同宣教模式对小学生钙营养知识、态度、行为的影响

目的 了解不同营养宣教方式对小学生钙营养知识、态度、行为的影响.方法 采用整群抽样的方式随机抽取4所小学的三～五年级的小学生作为研究对象,按析因设计原理随机分成4组后分别进行不同模式的营养宣教,在营养宣教前后分别调查他们的钙营养知识、态度、行为（K-A-P）方面的变化.结果 对小学生及其家长进行营养宣教对小学生的钙营养知识、态度和行为具有交互作用.小学生及其家长都接受营养宣教的小学生的钙营养知识、态度和行为得分营养宣教前后变化最大,在营养宣教前、后得分均值的95%可信区间分别为：钙营养知识0.441～0.464、0.538～0.561,营养态度0.684～0.723、0.743～0.780,膳食行为2.835～2.940、3.080～3.180.结论 为提高小学生的钙营养知识水平,端正营养态度,养成良好的膳食习惯,必须对小学生及其家长都进行营养宣教.

Influence of the mode of nutrition education on K-A-P about calcium nutrition in pupils

Objective To study the influence of different modes of nutrition education on the calcium nutrition knowledge,attitude and behavior(K-A-P) in pupils.?Methods Third-to-fifth-grade pupils drawn from four primary schools in Xuzhou using cluster sampling method,were divided into four groups according to the principle of factorial design to implement different-mode education.?Results There was interaction among pupils and their parents on K-A-P about calcium nutrition.The knowledge,attitude and behavior of the pupils in the group where both the pupils and their parents had attended the nutrition education,were improved significantly.The 95% confidence interval(95%CI) of the scores of knowledge before and after intervention were 0.441-0.464 vs 0.583-0.561;that of attitude,0.684-0.723 vs 0.743-0.780;and that of behavior,2.835-(2.940) vs 3.080-3.180.?Conclusion To implement nutrition education among both pupils and their parents is the preferable approach in promoting nutrition health among pupils.
