中国农村的限钠盐项目有助于降低钠盐摄入量

中国北方农村居民参加基于社区的限钠盐项目,并且能获得盐替代品之后,盐摄入量显著降低。作者Nicole Li博士(George全球健康研究所)介绍,“我们发现了一种低成本,实用的干预方法,可有效降低钠盐摄入量。” 中国农村健康行动限钠盐研究在120个村庄进行评估,平均钠盐摄入量为4.7~5.9 g/d,远高于世界卫生组织推荐的2 g/d的最大值。美国人平均每日摄入量为3

中国北方农村居民参加基于社区的限钠盐项目,并且能获得盐替代品之后,盐摄入量显著降低。作者Nicole Li博士(George全球健康研究所)介绍,“我们发现了一种低成本,实用的干预方法,可有效降低钠盐摄入量。”

中国农村健康行动限钠盐研究在120个村庄进行评估,平均钠盐摄入量为4.7~5.9 g/d,远高于世界卫生组织推荐的2 g/d的最大值。美国人平均每日摄入量为3.4 g/d.其中60个村庄未接受干预。其余村庄的居民接受社区卫生教育,建议其降低钠盐摄入量,对于心脏病高危的居民还有特殊信息。

此外,通过健康教育和农村便利店推广含钾的低钠盐。60个村庄进一步随机分为两组。30个村庄接受低钠盐的价格补贴。其余全价销售低钠盐。低钠盐价格约为普通盐2倍。

18个月后,研究者对每个村庄20个居民的24小时尿标本进行检测,计算其每日钠和钾摄入量。接受干预的村庄和未接受干预的村庄相比,每日钠摄入量降低13 mmol(17 mmol约等于1 g盐),钾摄入量增加7 mmol/L.接受低钠盐价格补贴的村庄每日钠摄入量降低17 mmol/L,钾摄入量增加9 mmol/L. Li介绍,“研究结果可在世界所有钠盐摄入以家庭烹饪用盐为主的类似环境中应用。”研究者正在同一地区进行更大规模的5年研究,以确定这一干预是否能降低高血压和卒中发生率。AHA目前推荐每日钠摄入量不超过1.5 g,以降低心血管疾病风险。
