上海市宝山区减少居民食盐摄入干预效果评价

目的评价上海市宝山区减少居民食盐摄入干预效果,为控盐干预工作提供依据。方法采用免费派发控盐勺等方法对上海市宝山区居民实施控盐干预,分别于干预前、干预后半年、1年和2年对160户家庭及家庭成员进行调查,分析人均日食盐摄入量及居民控盐知信行变化。结果 2年中,社区居民4项盐与健康知识平均知晓率由58.5%上升至79.2%;3项控盐态度平均形成率由72.2%上升至77.4%;平时能劝阻家人烧菜时减少食盐用量的比例由60.7%上升至68.4%,上述指标差异均有统计学意义(P<0.05),且存在1年内持续上升,1年后有所下降的变化趋势。人均日食盐摄入量干预前和干预后半年、1年、2年分别为8.00克、7.94克、7.41克和7.78克,差异无统计学意义(P>0.05);在摄入的盐中,隐形盐人均日摄入达1.65克;食用低钠盐的家庭仅占3.7%。结论控盐干预活动取得了一定的效果,但没有产生食盐摄入量的变化,因此控盐工作要持之以恒,同时要积极倡导食用低钠盐。
