179名居民食盐摄入量及相关因素分析

Analysis on salt intake and relevant factors of 179 residents

目的了解滨湖区居民食盐摄入情况,为减盐政策制定提供科学依据。方法采用多阶段整群随机抽样的方法 ,抽取滨湖区18~69岁居民180名,进行询问调查、体格测量和尿液收集。比较并分析不同特征调查对象和以不同特征分层后各食盐摄入量组间高血压患病率的差异。结果滨湖区居民每日食盐摄入量约为11.09 g;性别、年龄、文化程度、婚姻状况、职业与居民食盐摄入量差异无统计学意义;≤6g/d、>6~12g/d、>12g/d,3组人群的血压偏高率差异有统计学意义(X^2=6.19,P=-0.045);居民减盐知识知晓率与减盐行为率均不高,但减盐意愿较高。结论 2014年我区人均每日食盐摄入量过高,血压水平与食盐摄入量有关,需要制定减盐干预策略,加强健康教育,防控高盐饮食危害。
