目的:以学生为纽带,开展学校减盐宣传与教育,将减盐干预活动辐射到整个家庭,提高学生及家长低盐膳食和高血压防治知晓率及定量盐勺正确使用率,探索、完善以学校为基础推广家庭减盐的干预模式。方法:以小学四年级学生及其家长为目标人群,干预8个月。通过干预对象干预前后自身比较和与同时期对照对象比较,以KAP问卷调查、食盐摄入情况、体格检测和24小时尿钠检测结果为依据,评价“小手拉大手”学生及家长减盐干预模式的效果。结果:干预组膳食习惯正确率、盐与高血压相关知识知晓率,168名家长分别提高14.29%和36.53%,168名学生分别提高8.33%和62.95%;干预组人均食盐摄入量降低1.69g/人/天;干预组24h平均尿钠降低29.54mmol/L。结论:“小手拉大手”人群减盐干预系列活动的开展取得了明显效果,以学生为纽带、学校为基础带动家庭减盐的干预模式值得推广。
Aims: With the students as a link, carry out school salt reduction publicity and education, reduce salt intervention activities to the entire family, improve students and their parents awareness of low salt diet and hypertension prevention and control, and quantify the correct utilization rate of salt spoons, explore and improve School-based family promotion of salt intervention model. Methods: The fourth-grade students and their parents as the target population, intervention for 8 months. Compared with the control subjects in the same period before and after the intervention, the KAP questionnaire, salt intake, physical examination and 24-hour urine test were used to evaluate the effects of salt reduction Effect of intervention mode. Results: In the intervention group, the correct rate of dietary habits and the knowledge of salt and hypertension were raised. 168 parents increased by 14.29% and 36.53% respectively, and 168 students increased by 8.33% and 62.95% respectively. The per capita salt intake in the intervention group decreased by 1.69g / Person / day; 24h intervention group average urinary sodium decreased 29.54mmol / L. CONCLUSION: The series of “salt reduction intervention with small hand-pull-big-hand” have achieved remarkable results. The model of intervention based on student-linkages and school-based reduction of salt is worth popularizing.
