摘要
目的了解北京市城区和郊区中小学生家庭钠盐摄入量与相关知识行为情况,为制定相关的减盐策略和措施提供依据。方法方便选择北京市城区和郊区小学、初中各2所,整群抽取其中三～五年级小学生和七～八年级初中生,对愿意配合的903户学生家庭采用＂家庭1周钠盐摄入估算法＂测定钠盐摄入量,同时调查学生家长（常做饭的）钠盐相关知识和行为。结果北京市城区和郊区中小学生家庭的钠盐摄入量为（12.5±7.8）g/标准人日,在外就餐的摄入量高达（16.5±11.1）g/标准人日。家长（常做饭的）钠盐摄入相关知识行为总得分平均为（30.0±19.0）分。控制了地区、家长文化程度、2010年家庭年均总收入因素后,在家钠盐摄入量与知识行为总得分、行为得分和使用低钠盐得分呈负相关,回归系数分别为-0.030,-0.017,-0.017。结论北京市城区和郊区中小学生家庭的钠盐摄入量仍很高。普及减盐相关知识和技能、推广低钠盐、控制餐饮行业钠盐使用的社会活动或政策将是解决居民钠盐摄入过多的有效途径。
Objective To explore the relationship between sodium salt intake and related knowledge and behavior among family members of primary and middle students in urban and suburban of Beijing,and to provide the basis and strategy for followup health intervention.Methods The ＂ One week salt intake estimation method＂ was used to investigate the dietary salt intake of903 families who were willing to participate,chosen from students grade 3-5 in 4 primary schools and grade 7-8 in 4 middle schools in urban and suburban Beijing.A self-report questionnaire was used to survey the parents（often cook） related knowledge and behavior.Results The sodium salt intake of primary and middle students and their families in urban and suburban of Beijing was 12.5 ± 7.8 g per standard person day.When eating outside,the salt consumption reached 16.5 ± 11.1g per standard person day.The average score of sodium salt related knowledge and behaviors of parents（often cook） was 30.0 ± 19.0（full score 100points）.After controlling the area,parental education level and family annual income in 2010,the sodium salt intake eating at home was negatively related with the total score of knowledge and behavior,score of behavior and low-sodium salt usage,with the regression coefficient being-0.030,-0.017,-0.017,respectively.Conclusion The sodium salt intake of family members of primary and middle students in urban and suburban of Beijing is still high.Campaign and policies in improving salt reduction knowledge and skills,promoting the use of low-sodium salt and controlling the salt consumption in food industry will be the main solutions in salt reduction.
