【摘要】：目的了解广州市小学生膳食营养知识健康教育干预效果,为改善小学生营养状况提供依据。方法以等比例概率抽样的方法抽取广州市15所小学1 608名学生作为研究对象,干预形式为健康教育。干预前后分别进行问卷调查,最后进行干预的效果评价。结果干预后与干预前比较,相关营养知识总知晓率从68.07%上升到81.21%,差异有统计学意义(χ2=1 000.00,P0.01)。经过调整之后,除关于素食的正确观点干预前后无统计学意义(Z=-0.08,P=0.940),其他13项调查内容均有统计学意义(P值均0.05),且知晓率均为干预后高于干预前。经过调整混杂因素后,营养知识总知晓率干预后(81.39%)高于干预前(66.46%)(Z=-35.92,P0.01)。结论开展健康教育的干预手段对小学生膳食营养知识的提高是有效的。但是部分知识的干预效果相对较差,是今后健康教育的重点干预方向。
[Abstract]:Objective to investigate the effect of dietary nutrition knowledge and health education in primary school students in Guangzhou, and to provide evidence for improving primary school students' nutritional status. Methods 1 608 students from 15 primary schools in Guangzhou were selected by the method of equal proportion probability sampling. The intervention was in the form of health education. Questionnaire survey was conducted before and after intervention, and finally the effect of intervention was evaluated. Results compared with before intervention, the total awareness rate of related nutrition knowledge increased from 68.07% to 81.21, and the difference was statistically significant (蠂 2 / 1 000.000. 00g / P0.01). After adjustment, except for the correct view of vegetarian diet before and after intervention, there was no statistical significance before and after intervention (ZAI-0.08P0. 940), the other 13 items of investigation all had statistical significance (P 0.05). The rate of awareness after intervention was higher than that before intervention. After adjusting the confounding factors, the total awareness rate of nutrition knowledge after intervention (81.39%) was higher than that before intervention (66.46%) (ZJ-35.92 P0.01). Conclusion the intervention of health education is effective to improve the knowledge of dietary nutrition of primary school students. But the intervention effect of some knowledge is relatively poor, which is the key intervention direction of health education in the future.
