Abstract Excess dietary sodium is a modifiable cause of high blood pressure. The World Health Organization has targeted a 30 % reduction in mean population sodium consumption by 2025. In 2008, members of the International Food and Beverage Alliance (IFBA) made commitments to lower sodium content in their products. The aim of this study was to determine recent changes in sodium levels between 2013 and 2017 in foods and beverages produced by companies that are IFBA members (n = 10) and non-IFBA members (n = 6) that were included in the 2018 Global Access to Nutrition Index operating in Australia. Independent Samples t-tests and Mann Whitney U tests were used to test the differences in sodium levels. There was no clear difference in sodium content between 2013 and 2017 detectable for the IFBA members (mean difference 17 mg/100 g, 95 % confidence interval (CI), –82 to +48; p = 0.612; median difference 27 mg/100 g, p = 0.582). For the non-IFBA companies there was a decrease in median sodium content (−30 mg/100 g; P = 0.002) but not mean sodium content (−52 mg/100 g, 95 % CI −106 to +3; p = 0.064). Sodium reduction in IFBA companies appear to have had slow progress in Australia. Stronger implementation and monitoring programs are needed to drive industry action.

澳大利亚国际食品饮料协会会员企业加工食品钠含量变化：2013-2017

摘要 饮食中过量的钠是高血压的一个可改变的原因。世界卫生组织的目标是到 2025 年将平均人口钠消耗量减少 30%。2008 年，国际食品和饮料联盟 (IFBA) 的成员承诺降低其产品中的钠含量。本研究的目的是确定 2013 年至 2017 年间由 IFBA 成员（n = 10）和非 IFBA 成员（n = 6）的公司生产的食品和饮料中钠含量的近期变化，这些公司被列入 2018 年全球获取在澳大利亚运营的营养指数。独立样本 t 检验和 Mann Whitney U 检验用于测试钠水平的差异。IFBA 成员在 2013 年和 2017 年之间检测到的钠含量没有明显差异（平均差异 17 毫克/100 克，95% 置信区间 (CI)，–82 至 +48；p = 0.612；中值差异 27 毫克/100 克，p = 0.582）。对于非 IFBA 公司，钠含量中位数（-30 毫克/100 克；P = 0.002）有所下降，但钠含量没有下降（-52 毫克/100 克，95 % CI -106 至 +3；p = 0.064）。在澳大利亚，IFBA 公司的钠减少似乎进展缓慢。需要更强有力的实施和监测计划来推动行业行动。
