目的评价北京市西城区居民使用改良盐勺的干预效果。方法采用方便抽样在北京市西城区抽出两个社区（一个干预社区，一个对照社区），进行为期半年的社区干预试验，对干预社区居民发放改良盐勺并给予健康教育，评价指标包括盐勺使用态度、使用率和盐摄人量。结果经半年干预后，在≥60岁的居民当中，干预组和对照组认为“没人教如何使用限盐勺”“不知道限盐勺的正确用法”“现有限盐勺不好用”“使用限盐勺反而不知道放多少盐”的比例分别为10．3％和33．7％、6．9％和28．4％、14．9％和30．5％以及10．3％和22．1％，经常使用限盐勺的比例分别为70．1％和56．9％，日均盐摄入量分别为（3．37±2．17）g和（4．01±2．27）g，组间差异均具有统计学意义（P〈0．05）；在〈60岁的居民当中，干预组和对照组认为“做饭计算用盐量太麻烦”的比例分别为20．4％和29．7％，差异具有统计学意义（P〈0．05），两组的盐勺使用率均升高，盐摄人量均降低，但组间差异无统计学意义。结论发放改良盐勺可以提高盐勺使用率，降低盐摄人量，老年居民的干预效果较为明显。

Objective To evaluate the intervention effect of an improved salt-restriction-spoon using among residents in Xicheng District in Beijing. Methods Convenience sampling method was used to select two communities in Xicheng District, including an intervention community and a control community, to conduct a community intervention trial for half a year. An improved salt-restriction-spoon and corresponding health education were given to the participants in the intervention group. The attitude on salt-restriction-spoon using, the using rate of salt-restriction-spoon and the actual salt in-take were indicators for evaluating the intervention effect. Results After 6-month intervention, the percentages of participants aged above 60 in the intervention group and the control group agreeing that ＂no one teach me how to use a sah-restriction-spoon＂, ＂I do not know the correct usage of the salt-restriction-spoon＂, ＂the salt-restriction-spoon is inconvenient for use＂ and ＂the salt-restriction-spoon makes it difficult for me to know the amount of salt I have added during cooking＂ were 10. 3% vs 33.7% , 6. 9% vs 28.4% , 14. 9% vs 30. 5% , and 10. 3% vs 22. 1%, respectively. The using rate of salt-restriction-spoon in the intervention group and the control group was 70. 1% and 56. 9% and the daily salt intake was （3.37 ± 2. 17） g and （4. 01 ±2. 27） g, respeciively. Significant inter-group differences existed in the above mentioned indicators （ P 〈 0.05 ）. As to those aged under 60, the percentage of participants agreed that ＂it is troublesome to calculate the amount of salt＂ in the intervention group was significantly less （20. 4% vs 29.7%, P 〈0. 05）. The using rate of salt-restriction-spoon increased and the actual salt intake decreased in both groups, but no significant difference was observed between groups. Conclusion The improved salt-restriction-spoon can increase the using rate of salt-restriction-spoon and decrease the salt intake of people, especially among elderly population.
