【摘要】 目的 了解浙江省居民限盐勺使用情况，为优化减盐策略、防控慢性病提供依据。方法 采用多阶段分层随机抽样方法抽取浙江省5个县（市、区） 18～69岁居民为调查对象，收集基本情况、饮食行为和限盐勺使用等资料。分析限盐勺使用率和正确使用率，采用多因素logistic回归模型分析限盐勺使用的影响因素。结果 发放问卷7 601份，回收有效问卷7 509份，问卷有效率为98.79%。调查男性3 744人，占49.86%；女性3 765人，占50.14%。年龄为（44.81±14.03）岁。限盐勺使用率为11.97%，正确使用率为52.73%。多因素logistic回归分析结果显示，农村（OR=0.851,95%CI:0.731～0.991）、小学及以下文化程度（文盲/半文盲，OR=0.269,95%CI:0.172～0.420；小学，OR=0.595,95%CI:0.436～0.811）和食用盐摄入偏多（OR=0.718,95%CI:0.559～0.922）是居民使用限盐勺的阻碍因素；体育锻炼（OR=1.581,95%CI:1.362～1.836）和接受过低盐饮食健康教育（OR=2.082,95%CI:1.790～2.421）是居民使用限盐勺的促进因素。结论 浙江省居民限盐勺使用率较低，主要受到地区、文化程度、体育锻炼、食用盐摄入和接受过低盐饮食健康教育的影响；建议通过以技能提升和健康教育为核心，以渐进式干预为手段，推动居民使用限盐勺。更多还原

【Abstract】 Objective To investigate the status of salt-restriction spoons use among residents in Zhejiang Province,so as to provide evidence for optimizing salt-reduction intervention strategies and preventing chronic disease.Methods Residents aged 18-69 from five counties (cities/districts) in Zhejiang Province were selected using a multi-stage stratified random sampling method.Demographic characteristics,dietary habits,and salt-restriction spoons use were collected using questionnaires.The rate of salt-restriction spoons use and correct rate of salt-restriction spoons use were analyzed.Factors affecting salt-restriction spoons use among residents were analyzed by multivariable logistic regression model.Results Totally 7 601 questionnaires were allocated,and 7 509 valid questionnaires were recovered,with an effective recovery rate of 98.79%.The respondents included 3 744 males (49.86%) and 3 765 females (50.14%).The mean age was (44.81±14.03) years.The rate of salt-restriction spoons use was 11.97%,the correct rate of salt-restriction spoon use was 52.73%.Multivariable logistic regression analysis showed that rural (OR=0.851,95%CI:0.731-0.991),education level of primary school and below (illiterate or semi-literate,OR=0.269,95%CI:0.172-0.420;primary school,OR=0.595,95%CI:0.436-0.811),and excessive dietary salt intake (OR=0.718,95%CI:0.559-0.922) were inhibiting factors for salt-restriction spoons use among residents;physical exercise (OR=1.581,95%CI:1.362-1.836) and received health education on a low-salt diet (OR=2.082,95%CI:1.790-2.421) were promoting factors for salt-restriction spoons use among residents.Conclusions The rate of salt-restriction spoons use among residents in Zhejiang Province was relatively low,primarily influenced by region,educational level,physical activity,dietary salt intake,and health education on a low-salt diet.It is recommended that propose a multi-component intervention strategy centered on skill enhancement and health education,delivered through progressive staged implementation,to promote sustained adoption of salt-restriction spoons among residents.更多还原
