To analysis the usage status of salt control spoon and explore its influencing factors among student caregivers of four cities.
The data of 2014 salt knowledge, attitude, practice(KAP) survey among urban residents in China was used, which a total of 12 848 student caregivers(male 4862, female 7986) were recruited from Guangzhou, Wuhan, Chengdu and Shenyang by stratified random cluster sampling method. A self-filling questionnaire survey was used to collect information about knowledge of salt and usage of salt control spoon. Logistic regression model was used to explore influencing factors of salt control spoon usage effected by gender, education level, family income, salt related knowledge, etc. .
The proportion of student caregivers who didn't know salt control spoon was 33. 3%, and 41. 9% of them knew salt control spoon but hadn't it. Only 24. 8% of them have heard of salt control spoon and had it at home. The proportion of having not heard salt control spoon among Wuhan, male, junior high school and below, other occupation and low family income group was higher than other groups. The proportion of having salt control spoon of groups in Guangzhou, female, high school and above, professional technical and clerical personnel, high family income was higher than other groups, and the difference was statistically significant(P<0. 01). Among the student caregivers having salt control spoon, the proportion of did not used salt control spoon, used it occasionally or used it without controlling the quantity and used it often and controlled the quantity was 10. 0%, 60. 6% and 29. 5%, respectively. The student caregivers of Shenyang, male, high family income groups used salt control spoon and controlled the quantity more often than the other groups, and the difference was statistically significant(P<0. 05). As shown in multivariate logistic regression analysis, the OR(95%CI) of high school and above, high income level, knowing the recommended intake of salt, knowing that high salt diet can cause high blood pressure on the influence of having salt control spoon was 1. 328(1. 221-1. 445), 1. 268(1. 029-1. 563), 1. 243(1. 145-1. 348)and 0. 838(0. 763-0. 921), respectively. Among the student caregivers who having salt control spoon, the OR(95%CI) of knowing the recommended intake of salt, knowing that high salt diet can cause high blood pressure, and source of salt control spoon(community/unit, friends/relatives) on the influence of using salt control spoon was 1. 473(1. 259-1. 722), 1. 249(1. 040-1. 501)and 0. 505(0. 415-0. 615)/0. 603(0. 441-0. 823), respectively.
There still existed lower proportion of awareness and usage of salt control spoon.
分析控盐勺的使用状况，并探究中国四个城市学生家长群体中其使用的影响因素。
采用2014年中国城市居民盐知识、态度和行为（KAP）调查数据，通过分层随机整群抽样方法从广州、武汉、成都和沈阳招募了12848名学生家长（男4862名，女7986名）。采用自填式问卷调查收集盐知识及控盐勺使用情况等信息。运用Logistic回归模型探究性别、文化程度、家庭收入、盐相关知识等因素对控盐勺使用的影响。
不知道控盐勺的学生家长比例为33.3%，知道但家中没有控盐勺的占41.9%。仅有24.8%的学生家长听说过控盐勺且家中有控盐勺。武汉、男性、初中及以下文化程度、其他职业及家庭收入低的群体中没听说过控盐勺的比例高于其他群体。广州、女性、高中及以上文化程度、专业技术及文职人员、家庭收入高的群体中控盐勺拥有比例高于其他群体，差异有统计学意义（P<0.01）。在拥有控盐勺的学生家长中，未使用、偶尔使用或使用但不控制用量、经常使用且控制用量的比例分别为10.0%、60.6%和29.5%。沈阳、男性、家庭收入高的学生家长群体使用控盐勺并控制用量的情况多于其他群体，差异有统计学意义（P<0.05）。多因素Logistic回归分析显示，高中及以上文化程度、高收入水平、知晓盐推荐摄入量、知晓高盐饮食可致高血压对拥有控盐勺的影响的OR（95%CI）分别为1.328（1.221 - 1.445）、1.268（1.029 - 1.563）、1.243（1.145 - 1.348）和0.838（0.763 - 0.921）。在拥有控盐勺的学生家长中，知晓盐推荐摄入量、知晓高盐饮食可致高血压以及控盐勺来源（社区/单位、朋友/亲戚）对使用控盐勺影响的OR（95%CI）分别为1.473（1.259 - 1.722）、1.249（1.040 - 1.501）和0.505（0.415 - 0.615）/0.603（0.441 - 0.823）。
控盐勺的知晓率和使用率仍较低。
